Abstract
An apparatus comprises a lever provided in a housing. The lever has a stop piece on its first end which is located near a card insertion slot. The lever also has contact rollers on its second end which is opposite to the first end. The lever is rotatable around an axis with respect to a card passageway. The axis extends perpendicular to the passageway between the first and second ends. The lever is urged by a tension spring so that the contact rollers can contact a card being transferred in the passageway and that the stop piece cannot block the passageway. If a card is inserted from the insertion slot into the housing and transferred along the passageway, the card abuts the contact rollers to rotate the lever. As a result, the stop piece blocks the passageway to prevent successive insertion of two cards.
