A card carrier including pairs of rollers disposed at predetermined spacings along a card conveyer passageway such that the respective pairs of rollers hold both sides of a card therebetween. A driver including a single motor, a power transmission including a plurality of timing pulleys and a plurality of timing belts for transmitting the drive force of the motor to all the rollers, and power interrupting means including a clutch mechanism disposed between the power transmission and the motor for transmitting the drive force of the motor to the power transmission when the motor arrives at a predetermined rated rotational speed and a brake mechanism for stopping the operation of the power transmission instantaneously. When the motor arrives at the rated rotational speed, the clutch mechanism is actuated to drive all the rollers. When the card is to be stopped at a predetermined position, the drive force of all the rollers is stopped instantaneously by the clutch mechanism and the brake mechanism.
