Description

  The present invention relates to an internal arrangement of a camera provided with an imaging optical system unit configured with a bending optical system.

  Instead of a conventional film camera, an electronic camera is generally used that photoelectrically converts a subject image using a solid-state imaging device, performs predetermined processing, and converts the image into data to be recorded on a recording medium.

  In recent years, a reflective optical element has been placed in the optical system and the optical axis is bent at a substantially right angle, and the optical system does not protrude from the camera even when zooming is performed. Maintained cameras are also common. Similarly, lens barriers are also common.

With regard to the internal arrangement of the camera equipped with such a bending imaging optical system, when the camera is viewed from the subject side in order to eliminate the viewfinder parallax and the shift in the rotation direction of the captured image and the visually recognized image, the bending of the upper front of the camera A finder light incident aperture and a flash light emitting unit are arranged on the right side of the subject light incident aperture of the imaging optical system, and a battery is arranged on the left side of the bent imaging optical system (see, for example, Patent Document 1). .
