Abstract

Where card readers are provided in public places, it is desirable to prevent insertion of foreign objects into the card reading mechanism. The steps taken, however, must permit easy entrance or exit to properly positioned cards. Described is a gate suitable for use in the exit path of a card reader, which will prevent the insertion or entry of foreign objects into the card discharge chute. The gate member illustrated is pivoted at its upward end and as the card passes through the discharge chute, it engages the angled surface causing the gate to swing out of the way and permits the card to pass underneath the open gate as seen in dot and dashed lines. If an object is inserted in the wrong direction, the gate will not permit passage of the object since it is restricted in this movement by the adjacent wall structure.
