Description

  The present invention relates to a camera that includes a photographic optical system and an image sensor, and forms image data on the image sensor by the photographic optical system to generate image data.

  In recent years, a so-called digital camera of a type that forms an image of an object on an image sensor and generates image data has been rapidly spread, and the size and thickness of the camera have been increasing. In addition, various shapes have appeared in terms of design.

  One problem in such a flow is, for example, the problem of dimensional accuracy between the housing members or between the housing and the sliding door (sliding cover) on the front surface of the housing and in the meshing portion.

  If the dimensional accuracy of the connecting portion of the members is poor, a gap is opened in the connecting portion of the members when assembled, which may cause a design problem and may cause a function problem.

Patent Documents 1 and 2 show a state in which a plurality of members are combined in a camera or a photographing apparatus.
