Abstract

The printer built-in electric still camera has a pack chamber for loading a film pack, and a pack chamber door for opening and closing the pack chamber. On an inner face of the pack chamber door, plural film pressing devices are attached. When the pack chamber door is closed, the film pressing devices enter in a pack case from access openings formed on the pack case. The film pressing device has a frame and two pressure levers. The frame has a channel-shaped form and its bottom face is fixed on the pack chamber door. First and second shafts are attached to side plates of the frame, and ends of first and second pressure levers are rotatably fitted on the shafts. The first and second pressure levers are rotated by the bias of a strong spring and a weak spring. Other ends of the levers press the film unit.
