具えた自己診断装置。 In a self-diagnosis device for the board in a system in which a CPU, an IO register, and a board are respectively connected to a common bus, the same number of switches corresponding to all the boards required by the system are connected to the IO register, and , a photocoupler is provided in the bus connector of the common bus, and when the board is connected to the bus connector of the common bus, the board is simultaneously inserted into the socket of the photocoupler, and the board is connected to the bus connector of the common bus. When correctly inserted into the bus connector, the photocoupler operates through the individually provided small hole corresponding to the board and operates the switch corresponding to the board via the IO register, so that the board is properly inserted into the bus connector. 1. A self-diagnosis device equipped with a circuit board connection detection device, characterized in that a photocoupler is inoperative when the circuit board is not inserted into the circuit board, and detects whether the circuit board connection is good or not.
