<p>A dispenser for tickets comprises a feed hopper and a high speed drive mechanism. Tickets are dispensed from a hopper by means of a dispensing unit comprising a drive roller and an accelerator roller. The rollers are driven by a motor capable of dynamic braking and the rollers are adapted to operate at different speeds. The dispenser also comprises an infrared sensor, which counts the number of cards being dispensed. The dispenser is capable of accurate and high speed vending of tickets. A microprocessor circuit is used to control the drive motor, process signals from the sensor and monitor the inventory level in the feed hopper.</p> |
