Abstract

PURPOSE: To obtain a simplified, small-sized space saving shutter mechanism for preventing unjust intrusion of a card into a card reader or the like. CONSTITUTION: The card shutter mechanism comprises a shutter plate 2a for preventing intrusion of a card, and a thin electromagnet 1 for operating a movable member 2 having the shutter plate 2a at the forward end thereof. When the electromagnet 1 is conducted, the movable member 2 made of a thin spring plate is attracted to the electromagnet 1. Consequently, the shutter plate 2a at the forward end thereof projects into a card carrying path 3 which is thereby blocked. When conduction of the electromagnet 1 is interrupted, the movable member 2 is recovered by the spring force and the card carrying path 3 is opened to allow intrusion of the card.
