Abstract
A film or paper drive system for use in photographic film or paper cutters allows the operator to position the film or paper accurately and rapidly by actuating a switch. The film or paper is driven a predetermined distance at a first rate in response to actuation of the switch. If the switch remains actuated after a first period, the film or paper is driven at a second rate. If the switch still remains actuated after a second period, the film or paper is driven at a third, higher rate.
