<p>PROBLEM TO BE SOLVED: To prevent breakage of an inner electric part when live-line withdrawal is performed while suppressing cost increase.SOLUTION: A coin processor 1 comprises: a coin selection part 3; a coin storage part 2; and a harness 4. The coin storage part comprises a first connector 21 having a first terminal TH2, a second terminal TL1, and a first ground terminal TG1. The coin selection part comprises: a second connector 31 having a third terminal TH4 coupled to the first connector via the harness, to which high voltage is supplied via the first terminal, a fourth terminal TL2 for supplying low voltage to the second terminal, and a second ground terminal TG2 which is grounding via the first ground terminal; a low voltage power source circuit 32 for generating low voltage from the high voltage supplied to the third terminal and then outputting the low voltage from the low voltage output terminal 32t; and a switch circuit 34. The switch circuit blocks electric connection between the low voltage output terminal and the fourth terminal when difference between the voltage of the second ground terminal and the voltage of the low voltage output terminal is less than a threshold.</p> |
