A waterproof lens-fitted photo film unit includes a lens-fitted photo film unit. Between a case body and a rear lid, the lens-fitted photo film unit is contained in a watertight manner. A separation opening is formed in the case body. A separation access chamber has an entrance connected to the separation opening, and closes the separation opening in a watertight manner in a position interior with reference to the case body. The separation access chamber includes a thin wall having a small thickness, and is breakable by a separator tool having a long shape with a small width.

A film winding unit is removably attached to a film unit so as to engage a coupling gear with a film winding wheel. The coupling gear is connectable to a gear train through a clutch member. While the film winding wheel of the film unit is unlocked, the clutch member is placed in a power transmitting position for transmitting rotational movement of a motor to the coupling gear through the gear train. Upon the film winding mechanism being locked, a large load is applied to the clutch member, so that the clutch member slips into a disconnecting position to disconnect the motor from the coupling gear. In cooperation with the movement of the clutch member into the disconnecting position, a motor inactivating device inactivates the motor. After a release button of a film winding unit is depressed to depress a shutter button of the film unit, a motor activating device activates the motor in cooperation with returning movement of the release button. The rotational movement of the motor causes the clutch member to return to the power transmitting position, and is transmitted to the film winding wheel through the coupling gear.

A price printer for printing prices relative to photographic processing, which is suitable for a printer-processor for printing image recorded on photographic films onto photographic papers. The price printer is disposed in a position where each image printed on the photographic paper is detected. The number of defective prints selected by detection is input by an operator. The number of the defective prints is subtracted from the total number of prints which is automatically input from the printer-processor to calculate the number of prints to be delivered to a customer and compute a print price to be printed. Therefore, a proper statement of delivery can be made at a time and the efficiency of work can be improved. A photographic-film carrier capable of automatically detecting information about the length of a processed photographic film can be provided. The price printer can read the length information so as to determine the kind of the photographic film and automatically set and print a development price. A process for determining the development price by the operator can be eliminated and a further improvement in the work efficiency can be made.
