Abstract
A video record player includes a common drive belt for selectively translating a pickup stylus carriage. The player is equipped with a first drive mechanism, including a turntable-driven pulley, for utilizing the common drive belt for translating the carriage during playback toward the center of a turntable at a speed correlated to the speed of rotation of the turntable while stylus/record engagement is effected. A manually-actuated second drive mechanism is employed for utilizing the common drive belt for translating the carriage during active searching toward and away from the turntable center at a speed independent of the speed of rotation of the turntable while the stylus is in engagement with the record. The first drive mechanism includes a slip clutch interposed between the common drive belt and the turntable-driven pulley, whereby wresting of the control of the common drive belt by the manually-actuated, second drive mechanism from the first drive mechanism is permitted by the slip clutch upon actuation of the second drive mechanism. A mechanism for applying a constant drag on the turntable-driven pulley is provided to deter the rotation of the turntable-driven pulley in a reverse direction during operation of the manually-actuated, second drive mechanism in the reverse direction, whereby normal translation of the carriage by the first drive mechanism in the forward direction is resumed upon cessation of actuation of the second drive mechanism without delays due to effects of backlash in the first drive chain.
