Abstract
PURPOSE: To reduce the number of power source batteries to the minimum by decreasing the winding-up torque and using the motor torque efficiently, by performing the reciprocal motions of iris control mechanism and shutter charge mechanism by means of notch gears.
CONSTITUTION: Rotations of the motor are transmitted to a notch gear 35b through speed reducing gear train, and a winding-up plate 42 is rotated by way of a two- stage gear 41. Slide plates 43 and 44 are moved by the winding-up plate 42 to make linear motions to charge the shutter and iris control mechanism. After completion of charge, the engagement of the notch gear 35b and two-stage gear 41 is cleared, and the winding-up plate is rotated in the reverse direction by the elastic force of a spring 44b. Since the motor torque of the motor-driven winding-up mechanism can be efficiently used by the reciprocal motions of the slide plates 43 and 44, the number of power source batteries built in may be reduced to the minimum quantity, so that an extremely compact, and high performance camera may be constituted.
