The internal temperature sensor part 2 is arranged on the inside of the information reader 1 to measure an internal temperature of the information reader 1 at predetermined time intervals. The comparison determination part 4 determines whether unauthorized working is carried out or not based on the internal temperature measured by the internal temperature sensor part 2. The anomaly notification part 5 notifies unauthorized working when the comparison determination part 4 determines that unauthorized working has been carried out. <P>COPYRIGHT: (C)2008,JPO&INPIT |
