Title: Motor controller for focal distance switching camera
Inventor: KOMATSUZAKI HIROSHI
IPC: G03B17/00
Filed: 1988-01-08
Abstract: PURPOSE:To prevent a shutter device from being actuated in the middle of releasing operation by allowing a release switch to intervene between a 2nd motor switch and a focal distance switching switch, a frame feeding switch. CONSTITUTION:In a motor controller, a current is applied to the shutter device 31 after a main switch 18 becomes on by interlocking with a lens cover opening and closing knob. In such a case, the AF shutter device 31 is not actuated because a voltage is not put on an inhibiting terminal 31a and said terminal 31a is in an L signal state. When a release button is depressed and a movable armature of the release switch 20 is switched in such a state, an AF shutter actuating device 31 actuates the shutter so as to complete the photographing of one frame because the voltage of an electron 12 works on the inhibiting terminal 31a, which becomes in an H signal state. And when a TW switching operation and a frame feeding operation are performed, power supply to the shutter device 31 is prevented, so that the shutter device 31 is not actuated even in case of depressing the release button.

Abstract: PURPOSE: To provide a position detecting apparatus for moving body which can highly precisely detect the position of window glass, etc., of a power window apparatus, and besides, can set an initial position without complicated adjustment with a simple mechanism at a low cost. CONSTITUTION: As for the position detecting apparatus 30, a ring gear 46 rotates together with a motor output shaft and a prescribed rotary position is detected by a movable contact point 50 and a fixed contact point 60. In this case, the projected part 66 of a gear base 56 is brought into contact with a contact face 35 of a base plate 34, the difference of loss torque is widened between the gear base and the ring gear 46 and a planetary gear 54 does not rotate unnecessarily. At the time when the output shaft rotates after that, a carrier 56 is released from being held by a wave washer 58 and the rotation of the output shaft is not transmitted to the ring gear 46. Consequently, an initial state is automatically restored by sufficiently rotating the output shaft at the time of assembling.
