The intrinsic wiring of the printed board 10 is connected to a rear-surface connector 31 through a connector 12 for the intrinsic wiring. Pins 13 which are passed through through holes 25 of the back wiring board 21 are provided adjacent to the connector 12 and the positions and number of the pins 13 are decided in accordance with the kind of the printed board 10. Pin inserting terminals are provided on the rear-surface connector 31 in corresponding to the positions and number of the pins 13. |
