Next, the operation of the above embodiment will be explained.

First, the cover 13 of the feeding frame 8 is opened, the cartridge collecting box 14 inside is taken out, and the reader lock frame 20 is opened.

Next, as shown in FIG. 3, a plurality of films are made by connecting the leading end of the film 42 pulled out from the cartridge 41 to the rear end of the leader 22 using adhesive tape, etc., and the rear end of the first leader 22 is connected to the cartridge collecting box. 14, and the rear end of the next leader 22 is engaged with the second claw 18 from the front end of the cartridge collecting box 14.

When a plurality of readers 22 are installed in the stacking box 14 in this way, as shown in FIG.
The cartridges other than No. 1 are set in the collection box 14 with the leader 22 superimposed on the top.

Although the leader 22 is flexible, it has a certain degree of hardness, so when it is attached to the collection box 14 as described above, the rear edge of the leader 22 is pressed down on the stopper 24, and the hook of the detection piece 27 is pressed down. 29 is pushed rearward and the detection piece 27 is rotated as shown in FIG. 7, the stopper 24 engages with the perforation 23 at the rear end by the restoring force of the spring piece 25 as shown in FIG.

In this way, the upper end of the detection piece 27 is pushed backward by each leader 22, and the lower end of the detection piece 27 moves forward.

By the above operation, all the readers 22 are placed in the collection box 1.
4, close the reader lock frame 20 as shown in FIG.
The front part of each leader 22 protruding forward is placed on the protrusion 38, and each perforation 2
3 meshes with sprocket 36.

At this time, as shown in FIG. 7, the lower end of each detection piece 27 is within the detection range between the U-shaped sensors 40, and the signals from each sensor are used to display the display provided at a suitable location on the insertion box 1, etc. In the section, a display indicating that a reader is present is displayed and, for example, when 10 readers 22 are attached, a display of 10 is displayed.

Next, the cover 13 is closed to shield the interior of the cartridge collection box 14 from light, and the cartridge collection box 14 is set in the feed frame 8, after which the feed frame 8 is returned to the position shown by the solid line in FIG. At this time, the tip of the first leader 22 protruding from the cartridge collection box 14 has reached just before the cutter 43 in the insertion box 1. After that, when an automatic insertion start signal is sent from the keyboard to the control circuit, the interlocks (not shown) provided on the insertion cover 4 and the feed frame 8 to prevent them from being opened accidentally during processing are turned on, and the feed motor 33 is turned on. Turns on and infeed sprocket 3
6 starts rotating.

In this way, each leader 22 advances and moves along the guide frame 7, and the tip of the first leader 22 passes through the open cutter 43 and is detected by a detector provided in front of the drive roller 44 and the pressure roller 45. After that, the pressure roller 45 is attached to the drive roller 4.
4. Crimp.

At about the same time, infeed sprocket 36
When the feed sprocket 36 has rotated a quarter of a turn from the start of rotation, the constant feed detector detects the protrusion protruding from the side of the feed sprocket 36, and the feed motor 33 starts rotating.
It becomes OFF and the feed sprocket 36 stops.

At this point, the last hole of the perforation 23 of the first leader 22 is connected to the infeed sprocket 36.
Since it is further away, the first leader 2 that is crimped
Only the reader 2 is pulled out from the cartridge collection box 14 and sent.
mesh with.

Thereafter, the pressure roller 45 separates from the drive roller 44, and the leading leader 22 is fed into the developing section 2 by the feed sprocket 46 of the developing section 2.

Thereafter, when the cartridge 41 containing the film 42 connected to the rear end of the leading leader 22 comes off the front end of the feed frame 8, the cartridge 41 falls under its own weight and engages with a cartridge holder (not shown). , as the first leader 22 is fed, the film 42 stored in the cartridge 41 is pulled out, and when all the films 42 are pulled out, the cartridge 4
1 and the cartridge holder move forward along a guide rod (not shown) while compressing the spring, and when the cartridge holder reaches a predetermined position, the detector operates and presses the pressure roller 45 to the drive roller 44.
Thereafter, the drive means of the cutter 43 operates to separate the rear end of the film 42 from the cartridge 41. As a result, the cartridge holder rapidly retreats together with the cartridge 41 due to the repulsive force of the compressed spring, and the cartridge 41, which has been flipped up from the cartridge holder, falls into a cartridge collection box (not shown).

As mentioned above, the cutter 43 works and the film 42
After cutting off the rear end, the pressure roller 45 separates from the drive roller 44 and the sprocket 4 of the developing section 2
6, the cut film 42 is transferred to the developing section 2.
Send it to. Film 4 sent to developing section 2
When the detector detects the rear end of 2, the feed motor 33 is turned on, the sprocket 36 begins to rotate, and the next process begins.

By repeating the above process, the patrone collection box 1
4, the leader 22 disappears, and the final film 4
When the detector detects the rear end of 2, a termination alarm is issued.

In the above operation, every time one reader 22 is pulled out, all the readers 22 in the cartridge collection box 14 are removed.
moves forward together with the film 42 and the cartridge 41, and each trailing edge of all the leaders 22 slips out of the hook 18 as shown in FIG. Therefore, the rearmost detection piece 27, which was pushed by the rear end of the rearmost leader 22 and rotated and was sunk in the opening 26, returns due to the action of the spring 30, and its lower end becomes the detection range of the sensor 40. It comes off outside. As a result, the signal from the sensor 40 that was detecting the rearmost detection piece 27 is interrupted.
At this time, the other detection pieces 27 also try to return, but the rear ends of the shifted and stacked leaders 22 come into contact with the hooks 29 of these detection pieces 27 and press them down, so the hooks 29 close to the opening. Since the lower end of the other detection piece 27 is within the detection range of the sensor 40 and outputs a detection signal, the number of images displayed on the reader 22 is reduced by one.

In this way, each time the rear end of the rearmost reader 22 passes over the detection piece 27, the number of displayed sheets of the reader decreases, and when all the readers 22 come out, the displayed number becomes 0.

As described above, in this embodiment, along with the movement of the rear end of the rearmost reader 22, each detection piece 27 is returned sequentially to display the remaining number of sheets of the reader 22 installed in the patrone collection box 14. However, the present invention is not limited to this. For example, by setting the protrusion of the detection piece 27 from the opening 26 to the same height as the claw 18 or lower, the leading leader 22 is pulled out, and the trailing edge of all the leaders 22 is All the detection pieces 27 may be returned to their original positions at the time when the detection pieces 27 are removed from the claws 18. In this case, the signal from the sensor 40 when all the readers 22 are set is stored in the storage section, and the number of sheets set in the reader 22 is displayed. Thereafter, each time a sensor (not shown) separately provided at the tip of the feeding frame 8 detects the rear end of the leader 22 being pulled out, the display of the number of sheets set decreases by one, as in the above embodiment. .
