Lead-in FF and Return FF Lead-in FF . . . . This FF is set by pressingthe S/S (START/STOP) switch when the tonearm is on the arm rest, and is reset by a descend signal, or when the power switch is turned on. Return FF . . . . This FF is set by pressingthe S/S switch when the tonearm is not on the arm rest, and also by the end detector. It is reset when the power is turned on, or by the descend signal, or when the tonearm returns to the arm rest. b. When either of the above 2 FFs has been ser, an "AUTO on" signal is generated (as well as AUTO on), resulting in the arm elevator being set to the UP position, and inhibition of manual drive. I 5.2 END DETECTOR STAGE The end sensor input signal is rectified and then applied to the detector stage consisting of a differential circuit, integration circuit, and a monostable multivibrator. When the detector stage detects the arrival of 2 consecutive input signals within the fixed time constant period, an output signal is generated. This output, however, is inhibited by the EV Up signal when the arm elevator is in the Up position. OUTPUI E Vu p s q n a Fig. 5_1 5.3 ARM ELEVATION CONTROL STAGE This stage consists of a J-K-type FF with a reset (clear) input and preset input. The arm elevator is raised (Up position) as a result of the initial resetting, or by the AUTO operation signal from the tonearm control stage. The eleyator descend again (DOWN position) when the FF is preset by the descend signal. Furthermore, whenever the EV switch is pressed, Q and Q are generated alternately, resulting in the arm elevator being raised and lowered correspondingly. The FF output is applied to a logical ,,and" circuit with the outputs from the elevator Up and DOWN switches,the resultant output being applied to the EV motor drive stage. s.iA SIZE SELECTORSTAGE This stage consists of a J-K FF 2-stage ring counter and the QUQ2 logical ,,and,' gate. As a result of the initial resetting, Ql = Q2 = L for automatic switching of the size selector to the B0cm position. Every time the size selector switch is pressed after that, the selector is switched from the 30 to 25 and 17 positions in turn, and then back to 30 again. Note, however, that switching is inhibited when AUTO operation signals are received from the tonearm control stage (i.e. during lead-in, return, and repeat operations). 5.5 R E P E A TC O N T R O L S T A G E Consisting of a T-type FF, e and Q are inverted by Repeat switch operation. Note that the FF is also turned off by the initial reset, and that there is no inversion while the tonearm control stage return FF remains set (i.e. during return and repeat operations). Furthermore. the FF is also turned off as a result of auto-cut operation during repeat mode. 5.8 By motol senso f,onea opera is DC return 5.9 Thr CdS r voltag ment. the d to pa the to EITOT senso ./ 7V 5.6 LOWERING POSITION DETECTOR, PLUNGER CONTROL STAGE, AND D E S C E N DS I G N A L G E N E R A T O R When the tonearm shutter passesbetween the sensors corresponding to the designated record size (sensors being mounted in positions corresponding to each record size), a lowering position detector output signal is generated. This signal is then applied to the plunger control stage (a monstable multivibrator), resulting in a fixed time constant pulse signal being generated to activate the plunger (during lead-in and repeat modes). The down stroke of the pulse signal is differentiated and a descend position signal generated. Each of the tonearm control stageFFs is also cleared. 5.7 DISPLAYSTAGE AND PLUNGER DRIVER This stage is responsible for the LED display of elevator position, repeat mode, and selected record size, in addition to plunger drive. \ PL-L1 5.8 MANUAL DRIVE STAGE By amplifying the input to the power generator motor mounted in the locate stage, the tracking sensor stage balance is upset, permitting the tonearm to be moved back and forth. Such operation is inhibited, however, when the elevator is DOWN during auto operation modes (lead-in, retum, and repeat). 5.9 T R A C K I N G S E N S O RS T A G E A N D TONEARM DRIVER STAGE The tracking sensor stage (consisting of lamp, CdS element, and shutter) generates * and voltage differences in response to tonearm movement. These output signals are then applied to the driver stage where they are amplified, and to pass a current through the drive coil to drive the tonearm in such a way as to eliminate tracking elror (i.e. to avoid the generation of tracking sensoroutputs). 000 5.10 D.D. MOTOR CONTROL STAGE AND D.D. MOTOR STOP CONTROL The phono motor stop control stage stops the motor when the rest sensor detects the presence of the tonearm back on the arm rest. As long as the tonearm remains off the arm rest, the motor will continue to rotate. The phono motor control stage employs 3 specially designed ICs - PA2005, PA2OA4, and PD1003. These control stagesalso include the speed selector, speed indicator, and qtartz lock indicator circuits. End detector Loweringpositioi detector Restsensor Fis.5-2 PL-L1 c,Clc' €i.

LdenotesLlevel. HdenotesHlevelEV denotes arm elevator, UP denotes that arm elevator is in UP position, while DN that elevator is in the DOWN position. The Full Auto Logic section is made up of the following 5 main stages. (1) Tonearm control stage (2) End detector stage (3) Elevation control stage (4) Record size selector stage (5) Repeat control stage 6 . 1 . 1 T O N E A R M C O N T R O LS T A G E 1. When the power switch is turned on . . . . . . . . the lead-in FF and retum FF are reset by the initial reset signal (passed from C29lF-55 to IC16,-+ICI7,->IC9, and IC10). . . . . the phono motor will remain stationary if the tonearm is on the arm rest, but commence to rotate if it has alreadv been moved away. 2. When the START/STOP switch is then pressed with the tonearm on the arm rest, * Pin (8) of IC8 is switched to L level. * Pin (10) of IC8 is switched to H level, and this appears at pin (3) of IC10, resulting in the lead-in FF being set (and pin (10) of IC10 also being switched to H level). * Once pin (10) of IC10 is switched to H level, pin (3) of IC8 is switched to L level, resulting in pin (8) of IC1L being likewise switched to L level, thereby inhibiting manual drive (locate operation). Pin (13) of IC14 is also switched to L level, resulting in pin (12) of IC12 being switched to H level, and the elevator being consequently raised to the UP position. * Pin ( ) of IC11 is switched to H level, resulting in the inhibition of any further START/ STOP switch inputs after a delay of about lms (in order to prevent the return FF from being set when the tonearm leavesthe arm rest). At the same time, pin (12) of IC18 is switched to H level to inhibit switching of the size selector. Hence, the relevant FFs are set, the arm elevator raised, and record size selector switching inhibited. Pin (11-) of IC10 is switched to L, and this is transferred to pin (6) of ICS. Once the elevator is properly in the UP position, the UP detector switch is switched to the NO position, resulting in pin (5) of IC8 being switched to L level, and pin (4) of IC8 switched to H level. This IC8 pin (4) H level signal then turns Q7 on, resulting in a current being passedfrom VR8 to VRb and R99 via R93. If the potential at TP8 drops below the potential at TP10, the difference is amplified and a current passed through the coil to subsequently drive the czrlrier. The carrier is thus shifted across towards the record. (Assume size selector set to 30cm). When the carrier reachesa position about 20mm in front of the 30cm position, the carrier shutter will block the light of the 30cm sensor. Pin (13) of IC9 is thereby switched to L level, and pin (10) of IC9 switched to H level. This serves as a trigger for the monostable multivibrator incorporated in IC13, resulting in the generation of an H level signal of r = 2.2 sec. This is applied to TP3 and pin (9) of lCL2, presetting the EV FF for lowering of the tonearm. The TPB H level signal is used to drive IC7, and in turn attracts the plunger and raise the index plate. The carrier continues to move further, coming to a stop when the swing pin strikes the index plate. TP3 is switched back to L level 2.2 seconds later, the signal being differentiated by C34 and R44 to provide the tonearm descend signal which is passed via IC1-7, IC9 and IC10 to clear the FFs and stop the carrier drive current. The elevator UP, locate inhibition, and size selector switching inhibition are dlso cancelled at the sametime. As a further result of TPB being switched to L level, the charge held by C35 is dischargedvia R43 and the IC7 base resistance. During this discharge period (0.3 to 0.5 sec.) the plunger is maintained in the attracted position, but is forced back (by a spring) once the discharge has been eompleted. The elevator is thereby retumed to DOWN position for start of play. l 3. START/STOP switch pressed when tonearm is not on the arm rest x Pin (8) of IC8 is switched to L level. * The IC8 pin (10) change to H level results in pin (4) of IC10 being changed to L level for the retum FF to be set. * This then results in the elevator being raised, and inhibition of size selector switching, S/S switch input after a delay of 1ms, and locate. * The L level signal on pin (9) of IC9 is transferred to pins (5) and (6) of 1C72, thereby inhibiting inversion of the repeat FF. Furthermore, the IC10 pin (4) L level change is transferred to pin (4) of IC12 via pin (8) of IC14 to clear the repeat FF. The purpose of the 1ms delay circuit referred to above is to permit sufficient time for the generation of the time pulse employed in clearing this FF. * In a similar fashion to the lead-in operation, the L level signal appearing at pin (9) of IC9 once the elevator has been completely raised, is converted into an H signal at pin (11) of IC8, resulting in Q8 being turned on. In this case, however, the TP10 potential drops below the TP8 potential, resulting in the carrier being retumed towards the arm rest. x When the shutter cuts across the sensor light beam during the retum motion, pin (10) of IC9 is switched to H level, but since the repeat mode has been switched off, pin (1) of IC13 will be at H level, thereby preventing operation of the monostable multivator. t Once the carrier reaches the arm rest position, the rest sensor transfers and L level signal to pin (3) of IC16, resulting in pin (11) of IC11 being switched to L level to stop the phono motor. + When pin (11) of IC11 is switched to L level, the charge stored on C43 is discharged via R71, the return FF being cleared after the potential on pin (1) of IC9 is reduced to 1/2Vcc (delay circuit). During this period, the cauier remains pressedagainst the arm rest. 4. End detector operation * When the repeat mode is off, pin (3) of IC9 is switched to L level by the end detector, and the retum FF is consequently set. Subsequent steps are the same as during normal return mode. * When the repeat mode is on, the retum FF is again set in the same way for normal return operation. However, when the shutter cuts across the size sensor, the plunger is activated (TP3 switched to H level), followed by the generation of the descend signal in the same way as during lead-in. The elevator is thus lowered for recommencement of play. .Jl 6 . 1 . 2 E N D D E T E C T O RS T A G E 1.

When the left edge of the shutter slits reaches that position, the stylus tip will be at the R62.5mm position. That is, there is 20mm between the 62.5mm position and the point of entry into the detection range. Once the detection range is entered, the sensor commences to generate output signals with a waveform like that shown in Fig. 6-1-2 above. This out put is applied to the Schmitt trigger clcuit composed of 2 inverters in IC16 where it is rectified into the square wave as shown in Fig. 6-1-3. This output is then differentiated by C39/R61 and applied to pin (5) of IC14, while another portion of the same output is integrated by R62|C4O and applied to the monostable multivibrator composed of 2 NOR gates in IC18, resulting in the generationof a 1.06 1 0.1 secH level signal.(TPb). Although this signal is applied to pin (6) of IC14, there is no detection by pin (5) because of the delay by the integration circuit. If, however, the next differential pulse is applied to pin (5) of IC14 while the H level signal is being generated at TP5, that pulse will be detected. Apart from this case, there is no detection because the differential pulse involves a slight delay before switching TP5 q FL-L1 clclcl to H level. Furthermore, when the elevator FF Q is connected to pin (6) of IC18 to make Q = H (i.e. Up -position), the monostable multivibrator is inhibit_ ed, thereby inhibiting the detector circuit. Q = H also when the power switch is tumed on, again inhibiting the multivibrator. 6 . 1 . 3 E L E V A T I O N C O N T R O LS T A G E x When the power switch is turned on, an initial reset sigrral is passed to pin (12) of IC14 from R551C29, resulting in pin (11) of IC14 and pin (14) of IC12 being switched to H level (Q = H). This corresponds to the elevator being in the UP position, or in other words, Up priority is given when the power is first turned on. * Since Q = H, one of the ICZ transistors will be turned on to light up the Up indicator lamp. x Until the elevator reaches the Up position the UP detector switch remains in the NC position, resulting in pins (13) and (I2) of IC1Z being both switched to L level, and e13 and e16 of the elevator drive stage being both turned on to start up the motor. x Once the elevator is properly in the Up position, the UP detector switch is switched to the NO position, resulting in pin (18) of IC1? being switched to H level, and pin (11) of IC1Z being switched to L level. Q1B and e16 are both turned off and the motor stopped. x If the elevator switch is then pressed, a falling edge differential pulse is generated on pins (1) and (2) of lCL4, and a rising edge clock pulse on pin (13) of IC12. This results in Q = H and Q = L for lowering of the elevator (DN). * And since = H, the DN indicator lamp will be Q lit up, and the UP indicator turned off. x The DN detector switch remains in the NC position until the elevator is right down. During this period, pins (9) and (8) of IC1T will be both at L level, while pin (10) of IC1? will be at H level. The elevator drive stage e14 and Q15 will thus be on and the motor rotating. x If the elevator switch is pressed during this condition, Q will switch to L and Q to H (Up) to reversethe motor. The above description relates to the opera_ tion of the elevator circuit itself. In addition, * automatic mode UP (as described under the tonearm control stage),and * DN at the lowering position, may be controlled via the elevator FF preset and clear terminals. 6 . 1 . 4 R E C O R DS I Z E S E L E C T O RS T A G E x When the power is turned on, the initial reset signal from P"55lC29 is passed to IC16 to switch pin (11) to H level, resulting in IClb being cleared. * Pin (1) (Q1) and pin (15) (e2) of rClb are both switched to L level, this then being transferred to pins (8) and (9) of IC18. pin (10) of IC18 is thus switched to H level and the BOcm indicator lamp is lit up. * If the size selector is then pressed, the falling ' edge differential pulse applied to pin (18) of IC18 when pin (12) of this IC was at L level (i.e. when none of the lead-in, return, or repeat modes was operative), is instead applied to pin (11) of IC18 as a rising edge clock pulse, thereby activating the ring counter in IC1b. As a result, Q1 = H and Q2 = L. The BOcm indicator lamp is turned off, and the 2bcm indicator lamp turned on. * If the size selector is pressed again, the 17cm indicator lamp is turned on. Every time the selector is pressed, the size is switched in a cyclic order 30 -->25 -> L7. 6 . 1 . 5 R E P E A TC O N T R O L S T A G E * When the power is turned on, the intial reset signal from R55/C29 is applied to pin (g) of ICI4, resulting in pin (10) of this IC being switched to H level, and pin (1) (e) of. lCL2 being switched to L level. * The repeat indicator lamp will thus be turned off(sinceQ=L). x If the repeat switch is then pressed, a falling edge differential pulse will be applied to pins (5) and (6) of lCL7, and a rising edge clock pulse generated at pin (4). As long as the repeat or return modes are not operative at this time, pin (5) (K) and (6) (J) of IC12 will both be at H level, resulting in e - H, and Q = L for the repeat indicator to be turned on. At the same time, pin (13) of IC13 is switched to L level, thereby enabling the monostable multivibrator consisting of 2 gate circuits in IC1B to operate during repeat. x If the repeat switch is then pressed again, the J = K = H status will be inverted. In addition to the above repeat control stage, x The START/STOP switch may be pressed to activate return mode. In this case, a falling edge pulse is generated on pin (4) of IC10, and then applied to pin (S) of ICL . pin (10) of IC14 is thus switched to H level, and the IC12 FF cleared (repeat off), resulting in Q=LandQ=H. * When the retum FF is set (during return or repeat mode), pin (9) of IC9 is switched to L level, this being transferred to the J and K terminals of the repeat FF, thereby inhibiting any inversion.

When the stylus is positioned exactly at right angles to the carrier, the lamp Coil Ass'y beam is directed practically equally onto both P X B - I I 8 CdS elements, which means that the resistance in R=73t5rl (or 25('C) both elements will also be more or less equal. These 2 elements form part of a Wheatstone bridge with R93, R94, and VR8, this latter variable control being adjusted so that no potential difference is generated across TP8 and TP10 when the stylus is located at right angles to the carrier. If the stylus should happen to move to either left or right, the amount of light striking the CdS elements will change, resulting in the resistance of one element being increased, and the resistance in the other element being decreased. A potential difference will thus be generated across TP8 and TP10. The relation between stylus movement and the potential difference generated is shown in grasp form in Fig. 6-4. VR? is used for adjustment purposes. i< When the stylus is positioned at right angles to the carrier, the bridge is balanced, and the carrier remains stationary. * If the stylus should tend towards the left of the ca"rrier, a (+) potential will be generated across TP8 and TP10: This signal is amplified in the tonearm drive circuit (sec. 2.2 below), resulting in a coil current to move the carrier to the Ieft. (During record trace, or when moved to the left by hand). * If the stylus should happen to tend towards the right, a (-) potential will be generated TPlO@ across TP8 and TP10. After amplification in vol t the tonearm drive circuit, the resultant coil current serves to move the carrier to the right. (During record trace, or when moved to the right by hand). {€ During lead-in Q7 is turned on, and a current is pumsedfrom R93 to R99 via VR5. A (+) potential difference is generated between TP8 and TP10 by the voltage drop across R93, resulting in the carrier being moved to the left. Speed is controlled by adjusting the current Fis.6-4 passingthrough VR5. R PL-L1 clclcl * During return and repeat modes, Q8 is turned on, resulting in a current being passed from R94 to R98 via VR6. Consequently, a (-) potential difference is generated between TP8 and TP10 by the voltage drop across R94, thereby moving the carrier to the right. In this case, speed is controlled by adjusting the current passingthrough VR6. 6.2.2 TONEARM DRIVE CIRCUIT The tonearm drive circuit consists of a current booster formed by a differential amplifier and Qe - Q12. 1. Differential amplifier Consisting of a pair of op amps. 6.2.3 MANUAL OPERATION CIRCUIT (LOCATE OPERATIONCIRCUIT) x When elevator not completely in UP position (UP detector switch in NC position). x During automatic modes (lead-in, return, repeat). Under the above conditions, pin (10) of IC1l in the full auto logic stage is switched to H level, thereby tuming Q4 and Q5 on. The collector voltage of these 2 transistors will thus be almost zero. Current will also flow through the D10 R82 - Q4 and Dg - R81 - Q5 routes, resulting in the base of Q6 being biased in the reverse direction due to the voltage drop of Vp of D9 and D10 in respect to the emitter. eO is this tumed off to inhibit locate operation. * When locate dial is rotated. * When the motor generatespower. * When the motor rpm is low (slow rotation of the dial), the amplifier gain is determined by R76 + R7? + 1, but once the motor rpm is R7g increased to a certain rate, the gain will be clamped by the voltage determined by D7 and D8, or D5 and D6. * When the differential amplifier is activated, one side of Q6 is turned on according to the rotational direction of the dial, resulting in a voltage drop across R93 or R94, and the generation of a potential difference between TP8 and TP10. This is subsequently ampli fied, and results in a current being passed through the coil to move the carrier. Coil current Fis.6-5 7.
