Description of the Related Art Conventionally, in a camera of this type, a mounting board which constitutes an electric control circuit and the like is arranged along a built-in part having a plane part in the camera. In addition, a flexible printed circuit board (hereinafter referred to as an FPC) that is a connecting means for connecting to an electric circuit board, such as various electric parts in a camera
When a connector for electrical connection for electrically connecting (for example, a board) is to be provided, in order to allow the thickness of the mounting substrate and the connector for electrical connection to be arranged, a large mounting occupying area is required. It was what I needed.

FIG. 11 shows an example of a conventional camera of this type, and is a cross-sectional view showing one side of the camera in a partially enlarged manner. In the figure, the camera body, generally designated by reference numeral 1, includes a cartridge chamber 2 as a film chamber in which a well-known film cartridge F is loaded, and an aperture portion 3 through which a film drawn or drawn from the cartridge chamber 2 runs. I have it.

Reference numeral 4 denotes a well-known shutter unit arranged on the front side of the aperture portion 3 as shown by an imaginary line in the figure.
Reference numeral 5 denotes a dark box member which is a structural member disposed on the front surface side of the dark box member 5 so as to surround a shooting optical path from a shooting lens to a film. It is formed as an outer wall 5a.

Reference numeral 6 denotes a front body provided on the front side of the main body 1 so as to cover the dark box member 5 and the like by a joint portion 1a, and on the back side of the main body 1, as is well known, a camera back cover. (Not shown) and the like are arranged. Reference numeral 7 in the figure denotes a film rewinding fork that faces the inside of the cartridge chamber 2 and engages with the cartridge shaft of the film cartridge F loaded in the chamber 2 to rewind the film.

Reference numeral 2a in the drawing denotes a side flat surface portion of an outer wall forming the cartridge chamber 2, which is arranged so as to face the flat outer wall 5a of the dark box member 5 and is located on the outer wall 5a side of the dark box member 5 between them.
