UNAUTHORIZED DEVICE-USE PREVENTION SYSTEM AND DEVICE
First Claim
1. An unauthorized device-use prevention system that prevents an unauthorized use of a device by a third party, said system comprising:
- a device body; and
an attachment unit that is removably mounted on or connected to said device body;
whereinsaid attachment unit comprises a unit-side short-range wireless communication section that performs short-range wireless communication, which is a wireless communication over a preset short distance, with said device body; and
whereinsaid device body comprises;
a body-side short-range wireless communication section that performs short-range wireless communication with said attachment unit;
a unit authentication section that detects an attachment unit existing in a predetermined distance range via the short-range wireless communication to determine whether or not the detected attachment unit is a legitimate attachment unit; and
a lock control section that sets said device body in a lock state, in which a use of said device body is regulated, if said unit authentication section does not detect the legitimate attachment unit within a predetermined distance range.

Abstract
Disclosed is a system including a device which has a short-range wireless communication section in a device body and an attachment unit, removably mounted on or connected to the device body, for performing weak, short-range wireless communication between the device and the attachment unit. When it is detected that the device body and the attachment unit are disconnected, the weak communication is started between the body-side short-range wireless communication section and the unit-side short-range wireless communication section. If a body-side attachment unit authentication section does not detect a legitimate attachment unit within a weak communication range or if it is detected that the attachment unit is mounted on or connected to the device body, a controller of the device body notifies an error and the lock function of the controller inhibits the use of the device.
