In a conventional processing apparatus capable of performing a process from development to printing of a film, that is, a so-called simultaneous printing process, since the film is discharged through a printing section, a large amount of film is discharged. When the film is continuously processed, there is an inconvenience that reheating or additional printing of another film cannot be performed during the processing.

In addition, since the baking process requires a long time for the development process, in continuous processing of the film, the film is supplied to the film developing section at a required interval between the films, and the film is overlapped in the baking section. Need to be prevented. For this reason, even when the film is subjected to only the development processing, it is necessary to provide the same interval between the film and the preceding film as in the case of simultaneous printing processing, and there is a problem that the processing capacity is low.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and makes it possible to carry out reworking and reprinting operations during the continuous processing of a large number of films. The technical task is to improve the processing capacity.

The developer is sequentially transported into a plurality of processing tanks 23 filled with various processing liquids and developed.

A bypass path 32 for guiding the developed film to a second outlet 31 is branched from a film transport path 30 extending from the film developing section 1 to the printing section 10, and the transport path of the film F is switched to the branched section. Switching guide 33
Is provided.

FIG. 2 shows an example in which a switching guide 33 is provided downstream of the branch of the bypass passage 32. The rear end of the switching guide 33 in the transport direction of the film F is supported by a pin 34 so as to be swingable. The switching guide 33 and the motor 3
An arm 36 attached to the rotary shaft 5 is connected by a link 37, and the switching guide 33 is swung about the pin 34 by the drive of the motor 35.

FIG. 3 shows an example in which a switching guide 33 is provided above the branch portion of the bypass passage 32. Switching guide 3
3 is pivotally supported by a pin 34, and its switching guide 33 is connected to an arm 36 attached to the rotating shaft of a motor 35 by a link 37. The switching guide is driven by the motor 35. 33 is made to swing.

A film detector 38 and a feed roller 39 are provided in the film transport path 30 leading to the branch of the bypass path 32.
Are provided in order, and a feed roller 40 is also provided in the film transfer path from the branching section to the printing section 10.
The film feed speed of these feed rollers 39 and 40 is
The moving speed of the film F moving in the film developing section 1 is substantially equal to the moving speed.
