Digital camera

Abstract

A digital camera having an airtight chamber formed by a transparent dustproof plate placed adjacent a lens and pressure compensating or mitigating means. A main camera body and a transparent plate form an airtight chamber in a digital camera. A bellows or deflectable diaphragm is placed within the airtight chamber and coupled to a vent hole open to atmosphere outside of the main camera body. In an embodiment, a position adjusting mechanism moves an image pickup element in a vertical and lateral direction providing a perspective control mechanism.

What is claimed is: 
     
         1 . A digital camera that visually checks an image to be imaged on an image pickup element on an electronic display,
 wherein the image pickup element is provided at the rear portion of a camera main body,   a mount for an interchangeable lens is provided at the front portion of the camera main body,   a dustproof plate made of glass or resin is fastened to the inner side of the mount so as to prevent dust or the like from entering the camera main body, the dustproof glass or the resin plate is fixed as the dustproof plate to a position just after the interchangeable lens in the camera main body.   
     
     
         2 . A digital camera comprising:
 a camera main body having an inner rear surface on a rear portion and an inner front surface on a front portion, the inner rear surface opposing the inner front surface;   an image pickup element placed at the inner rear surface on the rear portion of said camera body;   an electronic display coupled to said camera main body, whereby said electronic display is capable of providing a visual check on an image formed by said image pickup element;   an interchangeable lens mount provided at the front portion of said camera main body; and   a dustproof plate fastened to the inner side of said interchangeable lens mount,   whereby dust is prevented from entering said camera main body at the time of interchanging an interchangeable lens.   
     
     
         3 . A digital camera comprising:
 a camera main body having an inner rear surface on a rear portion and an inner front surface on a front portion, the inner rear surface opposing the inner front surface;   an image pickup element placed at the inner rear surface on the rear portion of said camera body;   an electronic display coupled to said camera main body, whereby said electronic display is capable of providing a visual check on an image formed by said image pickup element;   an interchangeable lens section having a mount;   an interchangeable lens mount having an inner side mounted to the inner front surface on the front portion of said camera main body, said interchangeable lens mount corresponding to the mount of said interchangeable lens section, whereby said interchangeable lens section is capable of being mounted on said interchangeable lens mount; and   a dustproof plate fastened to the inner side of said interchangeable lens mount immediately adjacent said interchangeable lens section,   whereby dust is prevented from entering said camera main body at the time of interchanging said interchangeable lens section.
