ABSTRACT:
When a photo film package is inserted into a film holder body, a clip abuts against a slide lever to move the slide lever, whereby stopper pieces are projected into a passing area. When the photo film package is inserted into the final position, the clip is engaged with engageable pawls. At the time of photographing, a light shielding envelope is pulled out to expose a film F. During the operation of pulling out the light shielding envelope, a stopper tape abuts against the stopper pieces, a slide plate is slidably moved through the pulling force of the light shielding envelope, a control plate interlocking this movement is moved, and push vanes of the control plate push guide vanes, whereby the engageable pawls are retracted from the positions of being engaged with the clips. When the slide plate is moved, a push plate is raised to push a film unit toward a top lid. When the photographing is completed, the light shielding envelope is moved in a direction of inserting, the slide plate is returned to the initial position and the push plate is returned to the initial position. Then, the film unit is housed in the light shielding envelope, and thereafter, the light shielding envelope together with the film unit are taken out of the film holder body.
