ABSTRACT:
A card upside-down insertion preventive apparatus comprises a truncated corner portion formed at one end of a leading edge portion of a square card, a card tray disposed in a card insertion chamber communicating with a card inlet port, the card tray having a front abutment member and capable of moving in accordance with insertion of the card, the leading edge of the card being brought into abutment with the front abutment portion when the card is inserted through the card inlet port, a lock claw formed on the card tray, the lock claw being capable of displacing upwardly and downwardly in a direction perpendicular to the card insertion direction, a pressure receiving portion formed on the claw in a region within the truncated corner portion of the card which is in abutment with the front abutment member, the pressure receiving portion causing the lock claw to displace downwardly by being pressed by a non-truncated corner portion formed at the other end of the front edge portion of the card when the card is inserted upside down, and an engagement portion formed at a location corresponding to a lower surface of the card tray and adapted to engage the lock claw when the lock claw has displaced downwardly.
