ABSTRACT:
A ticket dispenser includes a drive roller and an idler roller so that power rotation of the drive roller advances tickets between them; the drive roller is movable toward and away from the idler roller and is so disposed and supported that a manual pull on the tickets to withdraw them when the power is off will serve to bind the tickets firmly between the rollers and prevent them from being pulled out.
