Tape recorder with counter drive mechanism responsive to tape movement

Abstract

A counter drive mechanism for use in a tape recorder having a resettable counter includes movable means preferably in the form of a rotatable disc having a tape engaging peripheral surface which abuts the tape such that the disc is rotated as the tape moves. The rotation of the disc is mechanically transferred to the counter to index same. Since the counter is driven in accordance with the movement of the tape, and not by the tape drive mechanism as is conventional, the accuracy of the counter is significantly enhanced. The peripheral surface of the disc is provided with a pair of electrically isolated conductive strips which, when electrically connected by contacting an electrically conductive foil strip on the tape, complete a circuit to energize the counter resetting means such that the counter is automatically reset at the appropriate tape position.
