A simple and compact apparatus for removing film from a film magazine includes a film slot opening/closing mechanism which is operated by a film slot opening/closing lever, and a spool driving shaft which is turned by a spool revolving knob. The apparatus further includes a film releasing mechanism. The mechanism has a structure such that a film releasing jig is inserted into a cartridge loaded with a film magazine through the film outlet slot of the cartridge by operating a film releasing jig lever.. The apparatus is used with a film magazine whose spool shaft has a film engagement claw therein. A hole formed in the tail end of film is engaged with the engagement claw. When the film releasing jig is inserted into the cartridge, the film is disengaged from the engagement claw. The film slot opening/closing lever, spool revolving knob, and film releasing jig lever are operated manually.

Photograph processing apparatus

A film-rewinding apparatus to rewind a film from a cartridge into a container which can accommodate the film therein by inserting the film from an opening of the container. The apparatus comprises a cartridge-supporting portion which supports the cartridge; a shielding door driving mechanism for opening and closing the shielding door; a spool-driving mechanism for feeding the film out by driving the spool; a container-supporting portion for supporting the container; an opening and closing driving mechanism for opening and closing the opening; and a film-dismounting mechanism for dismounting the film from the spool. The film-rewinding apparatus can easily perform rewinding by only operating a handle or lever, or by a switching operation, after the cartridge and the intermediate magazine are set and the cover is locked.

Film rewinding apparatus

Determination is made whether a film stored in a new type of film cartridge is developed or not before the film is processed. A detection sensor detects whether or not there is a nail on an outer wall of the new type of film cartridge to judge whether the film stored in the cartridge is developed or not. Infrared sensors and visible light sensors detect whether or not the film fed from the cartridge under the instruction of a control circuit is developed or not. If both the nail detection sensor and the infrared and visible light sensors give the same result, the result is judged to be correct.

A film winding apparatus for winding a film into a cartridge includes a film winding mechanism provided in an apparatus housing for turning a spool housed in the cartridge to wind the film around the spool. The film is inserted through a film inlet located on one side of the apparatus housing and fed toward the film winder. The cartridge loaded on a cartridge mount provided on another side of the apparatus housing is conveyed up to the film winding mechanism, where the cartridge is set in a film loading position. The film winding apparatus thus constructed offers easy operation without any special adjustment or treatment of the film or cartridge, yet featuring single-unit construction and portability.

Apparatus for attaching film on to a spool in a cartridge and winding

A film rewinder for rewinding film from a film cartridge to an intermediate cartridge. Its driving unit for rotating the film cartridge spool is also used to drive a tool for separating the film trailing end from the film cartridge spool. The film cartridge has a tool guide, so that the entire device is sufficiently compact. The film rewinder has a film cartridge receptacle and a winding unit for winding the film fed from the film cartridge into the intermediate cartridge. A film guide is provided between the receptacle and the winding unit. The spools of the two cartridges are driven by separate motors independently of each other. The tool is an arcuate member adapted to be pivoted in a circular path by the motor for the film cartridge. In order to minimize the length of the film guide and thus to minimize the size of the entire film rewinder, the film guide is provided with a release guide.

A film cartridge permits efficient resetting of a film stored in a film container. A cover is mounted on a cartridge body so as to be movable between an open position and a closed position. In the closed position, a film storage space is defined by the cover and the cartridge body. A film inlet/outlet slit communicates with the outside of the film storage space. A mounted in the film storage space are a spool and a guide plate for guiding a film inserted into the film storage space onto the outer periphery of the spool. The guide plate is pivotally supported. A roller is rotatably mounted on the end of the guide plate opposite the outer periphery of the spool. The guide plate is biased by a spring so that the roller is pressed against the spool. A film inserted through the film inlet/outlet into the film storage space is guided into between the spool and the roller by the guide plate. The spool is rotated in this state to wind the film around the spool.

Film cartridge

An automatic film developing apparatus for developing a photographic film being guided by a leader, comprising a film separating and forming mechanism for separating the developed film conveyed from the developing section of the apparatus from the leader, and forming the separated portion of the film into a specified shape. The developed film is automatically separated from the leader by the film separating and forming mechanism, and, at the same time, the separated portion is formed in a predetermined shape so as not to be caught in the guide of the negative mask or in a predetermined shape so as to be easily wound up in the cartridge, thereby saving the labor and enhancing the job efficiency.

An automatic film developing apparatus comprising a film drawing section for drawing out an exposed film wound in a cartridge, a developing section for developing the exposed film, a film wind-up section for winding up the developed film into the cartridge, and a cartridge conveying section for transferring the cartridge from the film drawing section to the film wind-up section. The cartridge from which the film is drawn out in the film drawing section is conveyed into the film wind-up section by the cartridge conveying section, so that the film can be securely put back into the original cartridge. Therefore, the film is not put into wrong cartridge by mistake. These film processing steps are carried out automatically, and hence the labor in the work is saved.
