Abstract
A changeover mechanism in the transmission of rotation of a drive source such as a reversible motor to an operating mechanism for the camera comprises a planetary clutch and is provided with a planetary changeover limiting member pivotally mounted on a common shaft of a planetary gear of the planetary clutch and frictionally connected thereto, whereby when the motor rotates in such a direction that the planetary gear engages a gear which is drivingly connected to the operating mechanism, release of the planetary gear from the engagement is inhibited, and when in the reverse direction, the planetary gear is permitted to disengage from the gear of the mechanism.
