PURPOSE: To shorten the distance between a top plate and a film, and provide a picture with high sharpness.

CONSTITUTION: A guide wheel is mounted on the lower part in a snapshot case 4, and a film holder 7 is guided and supported by the guide wheel and received in the case. A guide rail 8 is mounted on the upper surface of the snapshot case 4, and a cassette 12 supported by a dividing mask or cassette auxiliary frame 11 is installed on it. Thus, the guide rail 8 is commonly used in cassette photographing and snapshot dividing photographing, whereby it is not required to provide a cassette rail for supporting the cassette 12 in the inner part of the snapshot case 4, the distance between the top plate and a film can be shortened to provide a picture having a high sharpness. Since the guide rail 8 is commonly used, the number of parts for use are reduced, resulting in reduction in cost.
