Abstract
PURPOSE: To make automatic focusing easy by using the power source of the automatic winder of the camera for the automatic focusing mechanism incorporated in the camera and performing the automatic focusing of the photographing lens through the use of the rotating region of the winding mechanism of the camera at the time of its resetting to its original position upon completion of winding operation of the winding mechanism.
CONSTITUTION: A power winding drive motor 1 is connected to a power source 2, motor drive control circuit 3 and camera connection terminals 4, 4. The output shaft 5 of the motor 1 gives its revolving force to the winding drive system by a drive gear 7 via gear 6 to drive a winding drive shaft 8 via clutch mechanism 10. On the other hand, the focus drive system 26 of the photographing lens moves the rack rod 28 having a rack gear 27 which moves helicoid forward or backward. At the winding, the winding drive shaft 8 is turned in the winding direction by the motor 1 and when the winding drive is completed, the driving force is cut off by the clutch mechanism 10, causing a transmission gear 36 to be intermeshed with the drive gear 7. A focus drive system 26 is thereby driven.
