A mounting structure for a pressure plate in a camera 10. The camera 10 has i) a camera body with a back door 14 provided at the back of the camera body and ii) a pressure plate 18 disposed in the camera body. The mounting structure is designed for mounting the pressure plate 18 to the back door 14. The mounting structure comprises a leaf-spring member 20 disposed between the back door 14 and the pressure plate 18 for urging the pressure plate 18 in the forward direction of the camera 10. The three parts, i.e., the back door 14, the pressure plate 18 and the leaf-spring member 20, have various engaging portions provided on them, through which any two of the three parts are engageable with each other. The engagement between the back door 14 and the pressure plate 18, the engagement between the back door 14 and the leaf-spring member 20 and the engagement between the pressure plate 18 and the leaf-spring member 20 are maintained by means of the spring force provided by the leaf-spring member 20. The mounting structure uses only the three parts 14, 18 and 20. It uses no setscrew, no additional support member nor any other fixtures such as pins and clips, unlike any of prior art pressure plate mounting structures. The pressure plate mounting structure of the present invention can achieve considerable reduction in assembly costs of cameras.
