PROBLEM TO BE SOLVED: To prevent damage such as tearing at a part between perforations by preventing film from being caught by a sprocket when a film cartridge is loaded. SOLUTION: The cartridge loading chamber 36 of the camera 2 has shape fitted to the outer circumferential surface of the cartridge 4, so that the cartridge 4 can drop in a shaft direction. A plurality of teeth are formed on the sprocket 42 and the lower surface side of an outer periphery is an inclined surface. A detection part 51 is provided inside the cartridge loading chamber 36 and is turned on when the cartridge 4 is loaded. When the loading of the cartridge 4 is detected, a motor transmits rotational driving to the sprocket 42 to rotate the sprocket. COPYRIGHT: (C)2005,JPO&NCIPI
