发明名称 Mechanical power switching apparatus and camera
摘要 If a sun gear is rotated in the clockwise direction, a planetary arm is also rotated in the clockwise direction so as to permit the planetary gear and a transmission gear to be meshed with each other. If the sun gear is rotated in the clockwise direction under this state, a cam plate driven by a pin is rotated in the counterclockwise direction. A first engaging lever is rotated in the clockwise direction by a cam mounted to the rotary edge of the cam plate so as to release the engagement of the rotary edge of the planetary arm. If the sun gear is rotated in the counterclockwise direction under this state, the planetary arm is rotated in the counterclockwise direction so as to permit the planetary gear to be meshed with an idle gear. The planetary arm is engaged with a second engaging lever so as to maintain the meshed state between the planetary gear and the idle gear. If the sun gear is rotated in the counterclockwise direction under this state, a photographic film is wound up within a cartridge.
