Abstract
A card-feeding mechanism has two rollers positioned before a limiting device, and a roller and a sensor positioned after the limiting device. When a motor rotates clockwise, a transmission device drives the three rollers simultaneously to deliver a card from a front end toward a rear end. When the sensor detects an edge of the card, the motor rotates counterclockwise, and only drives the roller after the limiting device. Then, the card is only driven by the roller after the limiting device, and the rollers before the limiting device are driven by the card.
