发明名称 STEPPING MECHANISM FOR AUTOMATIC FOCUSING UTILIZING DRIVING POWER OF ELECTROMAGNETIC DRIVE SHUTTER
摘要 PURPOSE:To facilitate the adjustment of the setting mechanism of AF controlling by permitting driving of both of automatic focusing control and shutter control by using an electromagnetic device having a moving coil. CONSTITUTION:In a camera wherein a shutter exposure mechanism and an automatic focusing mechanism are controlled by a rotor 36 having a moving coil 37 provided in a magnetic field, a rotor 36 is turned like pulses by flowing pulse electric currents to a moving coil 37, and an AF control lever 8 of an automatic focusing (AF) mechanism is stepped when the pawl 21a of a clamping lever 21 hooks the next pawl of the position pawls 8a of the AF control lever 8. A distance lever 22 is moved to a correct photographing position by the lever 8.
