The film winding mechanism further includes a second device, engaged with the other end of the cartridge spool when the film cartridge is in the camera, for transmitting rotation of the cartridge spool in a film advancing direction to advance the film out of the film cartridge to the take-up spool so as to rotate the take-up spool in a film winding direction to wind the film.

Abstract: A remote control apparatus of a camera is provided which includes a signal emitter for emitting a remote release signal light, a camera body having a view finder, and an electromagnetic shutter. A half mirror is provided in the optical path of the view finder to partly transmit the remote release signal light therethrough and partly reflect the same. A light receiving element is provided behind the half mirror on the transmission side thereof, and a releasing device which releases the electromagnetic shutter of the camera body when the light receiving element receives the remote release signal light from the signal emitter is provided.

Abstract: A stereoscopic camera is provided with a mechanism to move reflective members into and out of an optical path such that the camera may take stereoscopic photographs in one position of the moving mechanism. The camera may also take normal full-frame photographs in a second position of the moving mechanism.

Abstract: A stereo photographing system having a stereo adapter for photographing two separate images of a same subject viewed from different points and formed onto one picture frame next to each other, and a camera including a finder and a photographing lens to which the stereo adapter can be detachably attached at the front end of the photographing lens. The stereo photographing system further includes a finder viewing field determining means provided in an optical path of the finder for selectively determining either a regular viewing field or a stereo viewing field, a detecting means which detects the stereo adapter when the stereo adapter is mounted to the camera, and a switching means which swatches between the regular viewing field and the stereo viewing field determined by the viewing field determining means in accordance with the detecting means.

Abstract: A camera having a remote controller provided separate from a body of the camera, wherein, based upon a signal outputted from the remote controller, a zoom lens of the camera is driven in accordance with calculated distance measuring data and a shutter of the camera is released. The camera includes a focal length detecting mechanism for detecting all existing focal length of the zoom lens, a mechanism for setting a framing mode in which a photographer carrying a remote controller is framed in a predetermined manner when the signal is output from the remote controller, a control mechanism for comparing a first focal length detected by the focal length detecting mechanism with a second focal length determined in the framing mode set by the setting mechanism, and for releasing the shutter under the condition that the first focal length is equal to or shorter than the second focal length.

Abstract: A camera is capable of photographing with a plurality of photographing aperture sizes, the largest one of the plurality of photographing aperture sizes being defined. At least one movable plate member is provided for converting a photographing aperture size into one, which is smaller than the largest of the plurality of predetermined photographing aperture sizes, and an optical system capable of advancing and retracting with respect to the camera body intersects with the movement plane of the at least one movable plate member when the optical system retracts. In such a camera, the at least one movable plate member is moved so as not to interfere with retraction of the optical system when it retracts.

Abstract: A camera capable of photographing with a plurality of photographing aperture sizes. Circuitry is provided to which electrical power is to be supplied; and a single operating member is capable of setting at least three different operating conditions. The circuitry is turned ON or OFF and a photographing aperture size is set to one of the plurality of photographing aperture sizes depending upon the operation condition set by the single operating member.

Abstract: In a camera system having a camera body and a remote controller detachably coupled to the camera body, at least one operation button is provided on the remote controller. A predetermined operation signal is transmitted from the remote controller to the camera body when the operation button is operated. Upon operation of the at least one operation button, selected one of predetermined operations is executed when the remote controller is coupled to the camera body. Another one of the predetermined operations is executed when the remote controller is detached from the camera body.

Abstract: A view finder of a zoom lens camera including a zoom lens, an object distance measuring device having a light emitter and a light receiver, and a zoom finder device which varies the field of view of the finder in association with the zoom lens. The zoom finder device is placed between the light emitter and the light receiver of the object distance measuring device.
