PURPOSE: To obtain a panorama switching device constituted so that shutter efficiency is high, operability is excellent and a camera main body is not obstructed to be made compact by realizing a full-size photographing and a panoramic photographing by operating a light shielding member.

CONSTITUTION: The upper and the lower light shielding plates 8 and 9 are disposed between the photographing aperture party (full-size photographing picture frame 5a) and the shutter of the camera main body and the supporting parts thereof are provided on the side surface of a shutter substrate part 1b so that they can be slid up and down. Besides, coupling levers 15 and 16 are positioned at the bottom dead point of a cam plate 12, and the light shielding of the frame 5a is executed by the plates 8 and 9. At this time, a closing action is executed by the plates 8 and 9 by a spring hung to the plates 8 and 9. Therefore, the picture frame is switched to the frame 5a by retreating the plates 8 and 9. On the contrary, the picture frame is switched to a panoramic photographing picture frame by actuating the light-shielding plates 8 and 9 to a prescribed light shielding position.
