To reproduce an image on the same condition as a recording state by forming an identically shaped hole tightly engaged with either positioning pin near to one side of rectangular film and forming a slot fit to the other positioning pin and extended in the arraying direction of both positioning pins.

When the reference pin being reference which is either of the positioning pins on the side of a viewer has a large diameter and the other pin has a small diameter, either positioning hole 191a of the positioning holes 191a and 191b formed on the film 191 for recording a stereoscopic image is tightly fit to the reference pin. On the other hand, the other positioning hole 191b is formed as the slot having the same diameter as the pin so that it is fit to the other pin and guided. Then, the positioning hole 191b being a slot is formed to be fit to the other positioning pin and extended in the arraying direction of both positioning pins. Thus, the film 191 is positioned on the same condition as a recording condition which is recorded.
