PURPOSE:To previously prevent insertion failure of a printed board by electrically judging whether or not an inserted printed board is correct by making use of contact between an electrode part provided on the side of a guide rail and an electrode part provided on the side of the printed board. CONSTITUTION:There is provided an electrode part 8 for identifying any printed board on the side of a guide rail 10 constituting an insertion path for a printed board 1, and are provided card edge connectors 3 each independently connected to identification information supply circuit on the side of the printed board 1. Provided the printed board 1 is inserted until it makes contact with a stepper 12 provided on the side of the guide rail 10, the card edge connectors 3 and the electrode parts 8 make contact with each other, and correctness of the inserted printed board 1 is electrically judged through a control part 80 connected to the electrode part 8 and a display part 90 and is displaced. For the printed board 1, the card edge connector 3 makes contact with the electrode parts 8 provided on the side of the guide rail 10 when the head part of the printed board 1 inserted along the guide rail 10 in the direction of an arrow x makes contact with the stepper 12. |
