Abstract
A card C having a predetermined thickness is guided by guide grooves formed in corresponding projecting portions of a card slot to enter. When the leading end of the card C is brought into contact with the lower edges of contact portions of a shutter member, the shutter member is pivoted about the front end sides of arm portions. A shutter plate arranged on the rear end side of the shutter member is moved upward to allow the card C having the predetermined thickness to pass deep. If a card C' having a thickness smaller than the predetermined thickness enters, a regulation portion projecting from the lower portion of the shutter plate of the shutter member is located lower than the bottom surface of a card passage. The leading end of the card C' having the smaller thickness is brought into contact with the regulation portion to prevent the card C' from entering deep. Even if the thin card C' is forcibly inserted, downward movement of the leading end of the card C' is regulated by the regulation portion, thereby preventing passage of the card C' and a card jam.
