摘要： A plurality of lens groups are moveable in the direction of an optical axis. A plurality of motors are provided for the lens groups, respectively. A driving circuit drives the motors. A switching section sequentially selects the motors and connects the selected motors to the driving circuit. A lens position-detecting section detects the positions of the lens groups. A driving control section sequentially drives the lens groups in accordance with intermediate target position data, respectively, via the switching section and the driving section, and determines whether the lens groups have reached their respective intermediate target positions, on the basis of the detection performed by the lens position-detecting section. When the driving control section determines that the lens groups have reached their respective intermediate target positions, it demands next intermediate target positions, which are slightly away from the initially-determined intermediate target positions. On the basis of the next intermediate target positions, the lens groups are driven again. With this operation repeated, the driving control section controls the driving of the lens groups until these lens groups reach their respective final target positions.

摘要： In a camera dedicated to a film feed type Patrone, one end of a spool axis of the Patrone or of an axis coupled with the spool axis is bared on the outer surface of the camera so that the spool axis can be driven externally. Bared contacts are provided to externally detect conditions within the camera.

摘要： Disclosed is a camera loaded selectively with either a first film having perforations formed in side edges or a second film having the same width as that of the first film and no perforations formed in side edges. The camera comprises: a picture size changeover device for selectively setting a photographing picture frame to a first picture size corresponding to the first film and a second picture size corresponding to the second film; a first lens installable and removable in and from the camera and having an image circle corresponding to the first picture size; a second lens installable and removable in and from the camera and having an image circle corresponding to the second picture size; and a device for judging which lens, the first lens or the second lens, to install in the camera. When the judging device judges that the first lens is installed in a state where the picture size is set to the second picture size, the picture size is so set as to be forcibly changed over to the first picture size.
