ELECTRIC DEVICE AND SERVICE METHOD OF ELECTRIC DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide an electric device capable of easily replacing a control board by supplying electricity to an exchanged-side control board and an exchanging-side control board from one power source, storing an integrated amount stored in a nonvolatile storing means of the exchanged-side control board in a nonvolatile storing means of the exchanging-side control board, and replacing the exchanged-side control board with the exchanging-side control board. PSOLUTION: This electric device has the control board having the nonvolatile storing means for storing the integrated amount of use time or use electric energy of the electric device, and a microcomputer for performing the writing to the nonvolatile storing means, and the control board has a connector integrally comprising a power source terminal for receiving or supplying electricity, and a transmission terminal for transmitting the integrated amount called up from the nonvolatile storing means by the microcomputer.
