ABSTRACT:
A ticket dispenser includes an adjustable tension device and a driver. The driver includes at least one sharp pin configured to pierce at least a portion of a thickness of a ticket strip and to pull the ticket strip in a direction along a ticket path. The ticket strip passes through the tension device as it is pulled by the driver. The tension device exerts a force on the ticket strip in a direction opposite the pulled direction. The driver can be a roller that is rotated by a motor. In addition, the ticket dispenser includes a driver guide which is adjacent and in close proximity to the driver. The ticket strip passes between the driver guide and the driver, thereby biasing the ticket strip in close proximity to the driver, and facilitating piercing of the ticket strip by the sharp pins. The driver guide includes rollers which have a groove extending around a circumference of the rollers. The sharp pins of the driver are aligned with and pass through the grooves which thereby further facilitate piercing of the ticket strip.
