PURPOSE:To prevent the generation of malfunction in a CPU by connecting a part of terminals of an ordered connector to the terminal of a power supply circuit and then resetting a microprocessor(MC) by signals generated by other terminals connected thereafter. CONSTITUTION:A device, e.g. a printed board 1, provided with an MC 4 and actively loaded/ejected to/from an external circuit, e.g. a case body side circuit 2 through an ordered connector 3 is constituted so that a part of terminals in the connector 3 is connected to the power supply circuit terminal at the time of connecting the connector 3, and the MC 4 is started by reset signals generated by other terminals 3-p, 3-q connected thereafter. Since the CPU 4 is not started in a state that the printed board 1 is actively loaded and only a power supply voltage is impressed to the board 1, the completion of connection of other connector terminals 3-p, 3-q is detected thereafter and the CPU 4 is started only by its detection signal. |
