invention is to be de?ned solely by the features of the present
invention according to the scope of claims appropriate from
the above descriptions.
What is claimed is:
1. A terminal device comprising:
a plurality of logical ports as ports for providing logical
unmount process or the execution instruction for the
mount process, on the basis of Whether the managed
number of pressing actions is an odd number or an even
number.
8. A terminal device comprising:
a plurality of logical ports as ports for providing logical
connections, the logical ports logically connecting
connections, the logical ports logically connecting
external devices to the terminal device, each external
device is logically connected only to the terminal device
external devices to the terminal device, and each exter
nal device is logically connected only to the terminal
by the logical ports;
device by the logical ports;
a receiver con?gured to receive an execution instruction for
an unmount process Which is a process of transition from
an activated state in Which the logical connections are
activated to a deactivated state in Which the logical con
nections are deactivated; and
a receiver con?gured to receive an execution instruction for
an unmount process Which is a process of transition from
an activated state in Which the logical connections are
activated to a deactivated state in Which the logical con
nections are deactivated;
a controller con?gured to control the logical ports, Wherein
the controller deactivates the logical connections corre
sponding to all the logical ports in response to the execu
a controller con?gured to control the logical ports, Wherein
the controller deactivates the logical connections corre
sponding to all the logical ports in response to the execu

prising an annunciator con?gured to annunciate that execu
tion of the unmount process is completed, When the transition
from the activated state to the deactivated state is completed.
13. The terminal device according to claim 8, further com
prising a press part con?gured to be pressed by a user,
Wherein the receiver receives the execution instruction for the
unmount process When the press part is pressed.
14. The terminal device according to claim 8, Wherein
the receiver receives an execution instruction for a mount

process Which is a process of transition from the deac
tivated state to the activated state,
the receiver manages a number of pressing actions in each
of Which a press part is pressed once, and When the press
part is pressed, the receiver determines Whether the
the receiver receives an execution instruction for a mount
process Which is a process of transition from the deac
tivated state to the activated state,
the receiver manages a number of pressing actions in each
tion for the mount process is received.
11. The terminal device according to claim 8, Wherein the
predetermined condition is an elapse of a predetermined
period of time after a receipt of the execution instruction for

receiver receives an execution instruction for a mount process
Which is a process of transition from the deactivated state to
external device communicating With each other, and
maintains the deactivate state of the logical connections
until a predetermined condition is satis?ed.
9. The terminal device according to claim 8, Wherein the
predetermined condition is physical removal of any of the
external devices.
10. The terminal device according to claim 8, Wherein the
