Terminal device
A terminal device including a plurality of logical ports as ports for providing logical connections, the logical ports logically connecting external devices to the terminal device, the terminal device comprising: a receiver configured 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 connections are deactivated; and a controller configured to control the logical ports, wherein the controller deactivates the logical connections corresponding to the logical ports, in response to the execution instruction for the unmount process.
1. A terminal device comprising:
a plurality of logical ports as ports for providing logical connections, the logical ports logically connecting external devices to the terminal device, and each external device is logically connected only to the terminal device by the logical ports;
a receiver configured 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 connections are deactivated;
a controller configured to control the logical ports, wherein the controller deactivates the logical connections corresponding to all the logical ports in response to the execution instruction for the unmount process without the external devices communicating with each other; and
a press part configured to be pressed by a user, wherein the pressed part is on the terminal device and the receiver receives the execution instruction for the unmount process after the press part is pressed.
2. The terminal device according to claim 1 , wherein the controller deactivates the logical connections corresponding to all the logical ports in response to the execution instruction for the unmount process, and maintains the deactivate state of the logical connections until a predetermined condition is satisfied.
3. The terminal device according to claim 2 , wherein the predetermined condition is physical removal of any of the external devices.
4. The terminal device according to claim 2 , wherein the receiver receives an execution instruction for a mount process which is a process of transition from the deactivated state to the activated state, and
the predetermined condition is that the execution instruction for the mount process is received.
5. The terminal device according to claim 2 , wherein the predetermined condition is an elapse of a predetermined period of time after a receipt of the execution instruction for the unmount process.
6. The terminal device according to claim 1 , further comprising an annunciator configured to annunciate that execution of the unmount process is completed, when the transition from the activated state to the deactivated state is completed.
7. The terminal device according to claim 1 , wherein
the receiver receives an execution instruction for a mount process which is a process of transition from the deactivated state to the activated state,
the receiver manages a number of pressing actions in each of which the press part is pressed once, and when the press part is pressed, the receiver determines whether the receiver has received the execution instruction for the 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 external devices to the terminal device, each external device is logically connected only to the terminal device by the logical ports;
a receiver configured 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 connections are deactivated; and
a controller configured to control the logical ports, wherein the controller deactivates the logical connections corresponding to all the logical ports in response to the execution instruction for the unmount process without the external device communicating with each other, and maintains the deactivate state of the logical connections until a predetermined condition is satisfied.
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 receiver receives an execution instruction for a mount process to transition from the deactivated state to the activated state, and the predetermined condition is that the execution instruction 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 the unmount process.
12. The terminal device according to claim 8 , further comprising an annunciator configured to annunciate that execution 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 comprising a press part configured 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 deactivated 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 receiver has received the execution instruction for the 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.
