Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a film transport device for transporting a film of a new type film cartridge into a photographic printing apparatus.

[0002]

2. Description of the Related Art When a film of a new type film cartridge is sent to various processing devices such as a photoprinting processing device,
The spool of the film cartridge is rotatably driven to feed the leading edge of the film, and the drive roller and pressure roller provided in the middle of the transport path presses the film further to feed the film, and when the film is completely pulled out from the cartridge, the end mark of the film is detected. It is a general transportation method to rewind the cartridge again.

A photoprinting processing apparatus employing such a transport method is known from Japanese Patent Laid-Open No. 7-36120. In this processing apparatus, a rotary table is provided on the substrate, and a plurality of cartridge holders are provided on the rotary table.
When the opposing holder is at a predetermined rotation position, the scanner unit and the printing / exposure unit are arranged on the substrate so as to face each other on a straight line passing through the holder, and the cartridge feeding unit is arranged at a right angle to the straight line. ing.

When the opposing cartridge holders of the above processing device come to the position facing the scanner section and the printing / exposure means, the film is transported between the cartridge holder and the scanner section, and between the cartridge holder and the printing / exposure means. By the method.

[0005]

By the way, in the case where the film is fed from the film cartridge fed to the cartridge holder on the rotary table in the above-mentioned transport path and the scanner processing or the printing exposure processing is performed,
The film is guided by the film guide and is gradually taken up by the film winder at the opposite end.

If the film cannot be conveyed due to a failure of the cartridge or other reasons during the conveyance of the film, the rotary table system cannot rotate the cartridge to the next phase position. This is because the film remains unwound between the film cartridge on the turntable and the winder.

In such a case, in order to remove the film, the film guide is removed from the substrate and taken out from the transport section in a state where the film is connected to the cartridge, and a thin film-like film removing plate (detaching tool) having elasticity is attached to the film cartridge. The film is inserted in the cartridge and the film is removed from the spool in the cartridge.

However, when a failure occurs in such film feeding, the work of removing the film guide each time is extremely troublesome and troublesome, and failure countermeasure processing cannot be performed quickly. Also, the cartridge, spool, or film may be damaged when the cartridge is removed.

In view of such a problem, the present invention removes the film from the cartridge spool without removing the film guide or the like, even if the film cannot be conveyed due to a failure of the cartridge or the like even while the film is being conveyed. An object of the present invention is to provide a transfer device that can be taken out from a container.

[0010]

As a means for solving the above-mentioned problems, the present invention has an elastic film detachment in a film conveying path adapted to guide and feed a film fed from a film cartridge through a film guide. The film transporting device for the photographic processing device is provided with a film insertion portion into which a tool can be inserted, and the film can be detached from the spool of the cartridge.

In such a film transport device, the film is fed through the film guide, and the film guide is provided with a film detection sensor, an end mark detection sensor, a feed roller, a scanner unit, a printing unit, and a viewer unit. Etc. are provided.

Therefore, if a failure occurs in the cartridge holder, the feed roller, or the like while the film is being fed out and a part of the film is being wound around the opponent of the winder or the processing device, the film is sandwiched between the film cartridges. Will remain.

In order to take out the film without damaging the film in such a state, it is conventionally necessary to disassemble the film cartridge and remove the film cartridge and the winder. In the present invention, however, the film cartridge is disassembled. The film can be taken out without.

The new type of film cartridge has its inner end locked to a protrusion in the spool of the film cartridge. Therefore, in order to remove the film end from the spool protrusion, most of the film is wound on the other side.
When the film reaches the end of the film, insert the tool insertion part in that state and separate the end from the spool.

Then, the film is further taken up by the winder, and all the remaining portion in the film guide is sent to the winder. In this winding machine, a winding machine is provided at the end of the film guide, and a part of the winding machine case can be opened and closed so that the film can be pulled out from the winding machine case. You can open the part and take out the film. As a result, the film can be taken out without removing the film guide.
