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.

Film holder

A sheet film pack has a pack housing for receiving a plurality of sheet film units, a lid for closing an opening of the pack housing, a film recovery mouth for recovering exposed sheet films, and a cap for closing the film recovery mouth and holding the lid in the close position. A film pack holder holds the sheet film pack in a sliding tray which is slidable in a holder housing. A cover having an exposure aperture is hinged to the holder housing and pivotally opened for loading the sheet film pack. When the cover is closed, the cap is released from the lid and the pack housing, and the cap is held in the holder housing. By sliding the lid out of and then back into the holder housing, the topmost sheet film unit is positioned in the exposure aperture and pressed by the lid into proper position. After photographing, by sliding lid out of and then back into the holder housing, the sliding tray is moved relative to the holder housing together with the lid, so that the exposed sheet film unit is fed into the bottom side of the pack housing through the film recovery mouth. A latch mechanism for preventing wrong motion of the lid and the sliding tray is incorporated in the film pack holder or in the pack housing. A counter disc is mounted in the sheet film pack, which can be coupled to a counter advancing mechanism mounted in the film pack holder, so as to advance the counter disc by one unit response to one reciprocating movement of the sliding tray.

A developer supply apparatus for a processing head which develops an image exposure-formed on an electrophotographic film by a developer. The developer, which is stored in a bottle, is pumped up to a switching valve by the expansion and contraction of a bellows. The switching valve is selectively set in two positions, that is, a first position for returning the pumped developer to the bottle thereby stirring the developer, and a second position for delivering the developer to the processing head to effect development. The bellows is capable of supplying an amount of developer which is required for the processing head to effect one developing operation with one stroke, thus enabling development to be reliably carried out.

Disclosed is a film cassette of a kind which contains an electrophotographic film therein and which is adapted to be loaded in an electrophotographic camera processor-reader. The film cassette includes a cassette casing formed with a reflecting-mirror insertion cavity into which a reflecting mirror is inserted in inclined relation for reflecting light emitted from a projecting light source to direct the light toward a projecting lens. Because of no necessity for incorporation of the elements including the projecting light source and reflecting mirror in the cassette casing, the size and weight of the film cassette itself can be reduced.
