However, when the photographer removes his or her line of sight from the viewfinder and checks the surroundings, it is difficult to perform agile operation if the camera body 61 is turned downward each time. The operability of the camera may be reduced. In addition, it takes extra time to return the camera body 61 to the normal shooting position from when the user looks away from the viewfinder to check the surroundings and starts shooting, and the shooting timing may be missed. For this reason, the workability of photographing may be reduced.

A major cause of the obstruction of the view to the surroundings is that the position of the line of sight looking into the viewfinder 64 is below the height of the front top wall of the camera body 61, and the camera body when looking around the surroundings. 61 is a barrier that hinders visibility. Therefore, viewfinder 64
Cameras whose gaze position is below the height of the front top wall of the camera body 61 are difficult to overlook the surroundings when the photographer removes his / her gaze from the viewfinder while carrying the camera. Is difficult to see through the camera body.

Accordingly, the present invention has been made in view of such a conventional problem. When a photographer looks around with a camera on his shoulder, the height of the front top wall of the camera body is reduced. The camera body 61, the slide mechanism 63, and the gripping member 65 are disposed at a position lower than the height of the line of sight when the camera is held.
So that the view of the photographer is not obstructed as much as possible,
An object of the present invention is to improve operability of a camera and workability of photographing.
