When, based on a detection signal from a cover opening/closing detection portion 25 , a CPU 20 recognizes that a cover is open, that is, a switch 61 is in an OFF state, the CPU 20 forbids wireless communication between a first transmitter-receiver 26 and a wireless tag 30 . By contrast, when, based on the detection signal from the cover opening/closing detection portion 25 , the CPU 20 recognizes that the cover is closed, that is, the switch 61 is in an ON state, the CPU 20 permits wireless communication between the first transmitter-receiver and the wireless tag 30.
