ABSTRACT:
A film reader includes individual drive systems for driving a storage reel to rewind a film strip and a take-up reel to unwind the film strip by pulling the film strip from the opposite reel. Each drive system is the same and includes a fast drive motor and a slow drive motor. A speed reduction pulley train has a first stage and a second stage connected in series with a first stage output pulley in drive coupling to an input pulley of the second stage by a one-way clutch. A slow speed motor is connected to the first stage. A one-way clutch connects a high speed motor in drive coupling to the opposite side of the input pulley. The output shaft is connected to the pulley train by a spring output clutch having a pulsed release control to disconnect the output shaft from the pulley train and permit free rotation thereof. The output clutch has a first drive coil wound on the shaft when driven and a second larger coil with the outer end turn slidably engaging a hub, which is reversely rotated to release the drive coil. Each one-way clutch is a simple wire coil wrapped about a shaft and having an end coupled to the driving member such that it winds the coil onto the shaft to transmit the rotation. A solid state control includes a switch unit having an interlock to insure proper setting of the output clutches before switchover of the drive systems.
