An upper guide 60 is arranged above the upper roller 36 to guide the transport leader 15 in and out, and a lower guide 61 is similarly arranged below the lower roller 40 to guide the transport leader 15. and return it.

The conveyance leader 15 is constructed as shown in FIGS. 6 and 7.

The conveyance leader 15 has an engagement hole 15b that engages with the conveyance leader sprocket 43 formed in the center of the leader body 15a. Disk mounting holes 15 are provided at symmetrical positions across the engagement hole 15b on the rear side of the conveyance leader body 15a in the conveyance direction.
c is formed, and a semicircular guide hole 15d through which the processing liquid passes is further formed around this.

As shown in FIG. 7, a disk film 62 and a roll film 63 are attached to this conveyance leader 15.

The roll film 63 is attached to the rear side of the conveyance leader 15 in the conveyance direction, for example, with a tape 64 or the like at its leading end. The disk film 62 is removably attached to the conveyance leader 15 by an attachment means 65 formed separately from the conveyance leader 15 .

Next, the operation of this embodiment will be explained.

When processing the disc film 62, a mounting means 65 is prepared, and for example, the disc film 6 is attached to the transport leader 15.
Install 2. This transport leader 15 is inserted from the dark bag 18 and set in the leader setting section 26.

When inserting the disc film 62 into the dark bag 18, even if some external light may enter the set box from the dark bag 18, the shutter 32 of the shielding means 30 is closed, and no light is allowed to pass through the film insertion slot 31. is prevented from entering the processing section. At this time, the roll film supply section 2 is shielded from light by the roller 3 to prevent external light from entering the processing section.

Next, this conveyance leader 15 is pushed in by hand, inserted into the leader insertion path 28 to a predetermined position, and set. When conveyance starts, the solenoid 34 is activated in conjunction with the shutter 32.
is opened and the disc film 62 is conveyed.

Then, the leading end of the conveyance leader 15 is guided by the upper guide 60, and the engagement hole 15c of the conveyance leader 15 engages with the conveyance leader sprocket 43 provided on the upper roller 36. As a result, the conveyance leader 15 is automatically drawn into the processing tank and conveyed by the intermediate rollers 37, 38, 39 and the conveyance leader sprocket 43 of the lower roller 40, and is guided by the lower roller 40 and the lower guide 61 and returned. Then, it is further transported from the upper guide 60 to the next processing tank.

The transport leader 15 is similarly transported and processed in the processing tank of the next step.

In addition, when processing the roll film 62, the mounting means 65 is removed from the conveyance leader 15, and the roll film 62 is attached to the rear end of the conveyance leader 15 externally as shown in FIG.
2 with tape 64 or the like. Then, open 417 of the set box 16, set the roll film 62 attached to the transport leader 15 in the holder receiver 19, insert and push the transport leader 15 into the transport port, and close the lid 17, and the roll film 62 will be automatically transported.

When opening this lid 17, the shutter 32 of the light shielding means 30
is closed to prevent outside light from entering the processing section.

FIG. 8 shows another embodiment, in which a sensor 66 is provided in the reader insertion path 28.

When the disc film 62 is transported through the transport leader 15, this sensor 66 detects the transport and turns on the solenoid 34 of the blocking means 30 to open the shutter 32 and allow the disc film 62 to pass through. It has become.

When the disc film 62 is not being conveyed, the solenoid 34 is in the OFF state, and the shutter 32 is closed by the return spring 33.
The film insertion port 31 is closed to block external light.

FIG. 9 shows yet another embodiment in which the light shielding means 30 is composed of a pair of light shielding rollers 67. This light-shielding roller 67 is pressed and pressed by, for example, a spring (not shown). When the disc film 62 passes, a spring is stretched by the transport leader 15 and the disc film 62 to create a gap so that the disc film 62 can pass through.

Further, the light-shielding roller 67 may be configured to create a gap when the disk film 62 passes by the action of a solenoid (not shown) to convey it.

In the above embodiment, the light shielding means 30 is the set box 1.
Although the disc film 62 is arranged inside the set box 6, a light shielding means 30 may be provided outside to shield the film insertion opening 31 of the set box 16 from light, and it may be opened when the disc film 62 is transported.

Although this embodiment has been described with respect to a photosensitive material processing apparatus that processes a disc film 62 and a roll film 63, the present invention is also applicable to an apparatus that processes only the disc film 62.

(Effects of the Invention) As described above, this invention is equipped with a light shielding means that opens when the disc film passes through the film insertion opening of the photosensitive material supply section, so when setting the disc film on the photosensitive material, etc. External light does not enter the processing section. Therefore,
Good processing is possible without causing fog on the photosensitive material.
