摘要： An automatic winding camera wherein winding operations such as wind-up, rewinding, frame feed, etc. of a film are automatically performed.In the camera according to the present invention, when the absence of the film in a film running path in a camera is detected by a film detecting device during winding of the film, a control device controls a driving device for driving a film winding mechanism to operate until a film winding detecting device detects that at least a predetermined length of the film is wound up. With this arrangement, when the film is rewound into a magazine after the takings, the forward end portion of the film can be entirely received in the magazine, so that such disadvantages can be obviated that dust intrudes into and light falls into the magazine.

摘要： An electronic flash charging circuit for use with a camera having a power source common to a microcomputer that controls a plurality of camera functions and to an electronic flash. The charging circuit has a booster circuit for boosting a charging voltage with which a main capacitor of the electronic flash is charged and a controller that causes the booster circuit to operate intermittently, thereby intermittently charging the main capacitor.
