  • Patent number: 5257054
    Abstract: A continuous taking camera, having eight consecutive exposure apertures, creates a picture frame having a size defined by alignment of two frames of 35 mm full size. Scenes for eight sub-frames are taken using the two full-size frames. Behind the exposure apertures, there are horizontally aligned two pressure plates each having a size corresponding to one frame of full size. When a photographic film is in the exposure station, the pressure plates hold the film flat. In a preferred embodiment, a spring plate biases the pressure plates to press the film. The pressure plates are retained on a rear door of the camera against the bias of the spring plate, so that the pressure plates are prevented from being dismounted from the rear door.

  • Patent number: 4903059
    Abstract: A camera is disclosed which is capable of winding and rewinding a film and adjusting a focal distance by use of a single motor. In the camera, the forward rotation of the motor is used to wind the film, and when the film winding operation is completed after termination of photographing, on detecting the end of the film, a torque detect mechanism switches a planetary clutch mechanism to connect the motor with a film rewinding mechanism. Thus, it is possible to perform both the film winding and rewinding operations by use of the rotation of the motor in the same direction. Also, when, with the planetary clutch mechanism connected with the film winding mechanism, the motor is rotated reversely, then the power transmission system is switched over to a focal distance varying mechanism, whereby the focal distance can be adjusted.
