摘要:
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.
