Abstract
A photographic camera has a camera back body on which are mounted an electronic circuit assembly including an external display system and the like and a pressure plate which is movable in the direction of the optical axis of a taking lens of the camera and supports the back side of a film loaded in the camera. A spring structure for urging the pressure plate toward the film includes a pair of torsion springs each having a linear shaft portion and a plurality of abutment portions extending substantially perpendicular to the shaft portion. The springs are disposed between the pressure plate and the camera back body so that the shaft portions of the respective torsion springs extend along opposite side edges of the pressure plate and a part of the abutment portions abuts against the pressure plate with the other abutment portions in abutment against a fixed portion on the camera back body. The shaft portions and the abutment portions of the respective torsion springs are disposed in spaces on opposite sides of the electronic circuit assembly without interference with the electronic circuit assembly.
