Document Type and Number:
Japanese Patent JPS5164926
Kind Code:
A
Abstract:
A movie sound camera wherein the motor for the sound shaft of the sound recording unit is started by a self-arresting rotary programming device prior to completion of the circuit of a sound amplifier, and the circuit of the amplifier is completed prior to starting of the motor for the pull down in response to movement of camera release from the idle position. When the release is returned to the idle position, the programming device automatically arrests the motor for the pull-down prior and the motor for the sound shaft subsequent to opening of the amplifier circuit. The programming device further controls the sequence in which the film is pressed against the sound shaft and biased against the second recording head of the recording unit in response to movement of release from the idle position. The programming device forms part of a control unit and is rotated by a motor which is started in response to movement of release to or from the idle position.
