is placed.

On the workbench 10 on the film loading side of the film carrier 12, there is an endless belt 16 for supplying film on which a large number of actual magazines 15 are placed side by side, and a film is set at the film drawer position of this supply side belt 16. A film pull-out means 18 is provided for pulling out the negative film 17 from the real magazine 15. Further, on the workbench 10 on the film exit side of the film carrier 12, there is an endless belt 20 on the film recovery side provided parallel to the supply side belt 16, and a film exit position of the film carrier 12 on the recovery side belt 20. Empty magazine 1 set in
A film storage means 19 for feeding a negative film 17 into the inside of the film 5A is arranged.

The magazine 15, as shown in FIGS. 2 and 3,
a storage section 25 that stores the negative film 17 in a roll;
The storage section 25 is provided with a film passage 26 through which the negative film 17 is introduced.

The film passage 26 is formed tangentially to the peripheral wall of the storage section 25. Further, a cover plate 27 covering the storage section 25 and the passage 26 is attached to the magazine body 29 via a shaft 28 so as to be openable and closable. The lid plate 27 is biased in the closing direction by a torsion spring 30. Negative film 1
As shown in FIG. 1, the film 7 is stored in such a way that the front or rear end of the film protrudes from the outer surface of the magazine 15 by about 20 mm.

In addition, there are recesses 31 and 32 on the front and rear lower sides of the magazine 150.
is formed, and a locking portion 33 is formed to protrude from the center of this recess. A setting member 35, which will be described later, is engaged with this engagement portion 33, thereby setting each magazine 15.15A at the film extraction position.

As shown in FIG. 1, the moving belts 16.20 on the supply side and the recovery side have a length that allows a large number of magazines 15 to be lined up in the horizontal direction, and are arranged between rollers 37° and 39.4°.
It is stretched horizontally between 0 and 0.

Each of these moving bells) 16.20 is driven by a pulse motor 41.
42. Also, each moving bell) 16.20
Magazine guides 42 are attached to both sides of the belt to prevent the magazine 15.15A on the belt from falling off. Furthermore, the film leading end 1 of the supply side moving belt 16
A leading end guide 46 for guiding the film leading end 17A to the gap between the pair of drawing rollers 45 of the film drawing means 18 is attached to the side where film drawing device 7A is located. As shown in FIG. 4, the tip guide 46 is composed of a lower guide 47 and an upper guide plate 48.

A gap is formed between each of these guide plates 47, 48, and the film leading end 17A moves within this gap. The upper guide plate 48 is attached to the lower guide plate 47 so as to open upward, and when setting the magazine 15 on the moving belt 16, open the upper guide plate 48 upward and set the film leading edge 17. do. Further, a stopper 49 for the magazine 15.15A is provided at the end of each moving belt 16.20, and each magazine that has finished transporting the film is stored at the end position. At this time, each magazine stopped by the stopper 49 slips on the belt when the belt 16.20 rotates.

A magazine detection sensor 50 for detecting the actual magazine 15 set in front of the film pull-out means 18 is arranged on the workbench 10. Although an optical sensor is used as the sensor 50, a limit switch may also be used. A magazine detection signal output from the sensor 50 is sent to the controller 51.

The controller 51 is composed of a well-known microcomputer, and controls each pulse motor and solenoid based on a control program stored in a ROM, signals from each sensor, and command signals from a keyboard 52. Then, based on the magazine detection signal, the controller 5
1 stops the rotation of the pulse motor 41 of the moving belt 16 to stop the actual magazine 15 at the film drawing position, and also causes the magazine setting means 52 to
to the film drawer position.

As shown in FIG. 3, the magazine setting means 52 includes a lock lever 53 that locks onto the locking portion 33 of the magazine 15. The lock lever 53 is rotatably attached to the base 54, and is displaced by a solenoid 55 between a retracted position in which it is flipped upward and a locking position in which it is horizontal.

A lock lever 53 is attached to the plunger 56 of the solenoid 55.
A coil spring 57 is attached to urge the solenoid 53 downward, and when the solenoid 55 is turned off, the lock lever 53 is set to the locking position. Further, when the solenoid 55 is turned on, the lock lever 53 is lifted upward and set to the retracted position so that it does not become an obstacle to the movement of the magazine 15. The tip of the lock lever 53 is bifurcated, and the locking portion 33 of the magazine 15 is held between both sides by this tip.

The film drawing means 18 is constructed as shown in FIGS. 3 and 4. FIG. 3 shows a state in which the leading end 17A of the film of the actual magazine 15 is inserted into the pull-out roller pair 45 of the film pull-out means 18.

As mentioned above, since the film leading end 17A protrudes from the outer surface of the real magazine 15, when the real magazine 15 is set at the pull-out position, the film leading edge 17A will come into contact with the nip of the pull-out roller pair 45. It turns out. For this reason, when the actual magazine 15 is set at the pull-out position, the controller 51 releases the nip between the pull-out roller pair 45 and lifts the upper roller 60 upward. The upper roller 60 is rotatably attached to a movable frame 61 that moves in parallel in the vertical direction.

The movable frame 61 is urged downward by a coil spring 62, and is lifted upward by the solenoid 63 when the solenoid 63 is turned on.

When the magazine detection sensor 50 detects that the real magazine 15 is set in the drawer position, the controller 51
In this case, the solenoid 63 is turned OFF, the upper roller 60 is displaced downward by the force of the spring 62, and the film leading edge 1 is moved downward.
7A is nipped between the pull-out roller pair 45. After nipping, as shown in FIG. 4, the lower roller 66 is rotated by a predetermined amount via the timing belt 64 and pulse motor 65.
The negative film 17 is transferred to the exposure position of the film carrier 12. At this time, a screen detection sensor (not shown) of the film carrier 12 detects the screen position, and based on this, the screen is set at the exposure position.

Then, printing exposure is performed at this position. In addition to setting the screens using the screen detection sensor, each screen can also be set by detecting notches provided in advance corresponding to each screen of the negative film 17, as is well known. Furthermore, instead of automatic frame advance, it is also possible to set the screen to the exposure position while operating the frame advance key.

The film storage means 19 and the film recovery side moving belt 20 are constructed in the same way as the film drawer means 18 and the film supply side moving belt 16, and the same constituent members are given the same reference numerals and the explanation thereof will be omitted. . Further, the magazine setting means 67 attached to the film collection side belt 20 is also connected to the magazine setting means 52 on the film supply side.
The configuration is similar to that, and the explanation thereof will be omitted.

A film detection sensor 68 is arranged on the film exit side of the film carrier 12 to detect the film leading end 17A. Based on the film leading edge detection signal from the sensor 68, the controller 51 rotates the motor 65 of the film storage means 19 to feed the negative film 17 into the empty magazine 15A. Further, when the film detection sensor 68 detects a film end signal, the controller 51 rotates the motor 65 by a predetermined amount to store the negative film 17 in the empty magazine 15A. At this time, when the rear end of the negative film 17 leaves the pair of feed rollers of the film storage means 19, the negative film 17 is no longer sent into the empty magazine 15A, and the rear end of the negative film 17 leaves the magazine 15. It is stored with a slight protrusion. This makes it possible to easily pull out the negative film 17 from the magazine 15. After storing the film in the magazine 15, the nip between each pair of rollers 45 of the film extracting means 1B and the film storing means 19 is released, and the setting of the magazine setting means 52, 67 is released. Thereafter, each moving belt 16.degree. 20 is rotated to set the next magazine at each position.

Next, the operation of this embodiment will be explained.

First, the actual magazine 15 is moved to the film supply side moving belt 16.
Set multiple pieces on top. At this time, open the upper guide plate 48 of the tip guide 46 and insert the film tip 17 into the guide 46.
Also set. Further, a large number of empty magazines 15A are set on the film recovery side moving belt 20. At this time,
It is only necessary to appropriately place each magazine 15.15A on the belt, and the setting can be easily performed. Next, when the start button on the keyboard 52 is operated by the operator, the controller 51 rotates each moving belt 16.degree. 20 to place the first magazine in the film draw-out position and the film storage position. This setting is performed based on the signals from each magazine detection sensor 50.

Next, the magazine setting means 52.67 is operated to fix the magazines 15.15A at each position.

Next, the film pulling means 18 is operated to set the negative film 17 at the exposure position of the film carrier 12 and perform printing exposure. When each screen is sequentially printed and exposed to the color heparin, the controller 51 uses the tip detection signal from the film detection sensor 68 to control the film extraction means 19.
The negative film 17 is fed into the empty magazine 15 by rotating the pulse motor 65. Storage section 25 of magazine 15
is a cylindrical cavity, so the film tip 17A is stored in a roll along the peripheral wall.

When the printing exposure of one magazine's worth of negative film 17 is completed, the controller 57 controls each moving bell l-1 in response to a film end signal from the film leading edge detection sensor 68.
6 and 20, the magazines 15A and 15 that have been transferred are ejected from the film drawer position and the film storage position, and new magazines 15 and 15A are set at each position. Thereafter, the negative film 17 is pulled out from the second real magazine 15 in the same manner as the first magazine 15.15A, and after each screen is printed and exposed, it is stored in the second empty magazine 15A. New real magazine 15
By appropriately setting the cartridges in empty spaces on the magazine supply side of the moving belt 16, printing processing can be performed continuously. Further, the empty magazines 15A accumulated on the exit side stopper 49 of the magazine supply side moving belt 16 are transferred to the film recovery side moving belt 20 as appropriate. Further, the magazine 15 containing all the negative films 17 that have been subjected to printing exposure is appropriately taken out from the recovery side moving belt 20 and set in the negative cutter for the next process.

The above embodiment describes a feeding device for setting developed film at the exposure position of a printer. The present invention can also be practiced.

In the above embodiment, the end signal from the film detection sensor 68 disposed at the film output side position of the film carrier 12 causes the first and second moving bells) 16.2
0 are operated at the same time, but instead of this, film end sensors may be provided on both the first and second moving belts, and the respective moving belts may be operated individually based on this signal.

Further, in the above embodiment, the rotation of each moving bell (16, 20) is controlled by the signal from the magazine detection sensor 50,
Each magazine 15.15A is set at the film drawer position and the film storage position, but instead of this, a magazine stopper is provided at each position, and this magazine stopper is made to appear and retract on each moving belt. You can also set the magazine in the position.

Further, in the above embodiment, the magazine 15 provided with the cylindrical storage portion 25 is used, but a magazine having a reel rotatably provided within the case may also be used. In this case, the film storage means is constituted by a reel rotating roller that rotates the reel in the magazine instead of the feeding means 19 that forcibly feeds the film into the magazine 15. Then, the reel rotating roller is swingably attached by an arm or the like so as to retreat from the magazine transfer path so that the reel rotating roller does not hit the magazine case when the magazine is moved.

Further, the film drawer means and the film storage means may be constructed as shown in FIG. In this case, the upper roller 72 of the pull-out roller pair 71 is moved by the swinging arm 73 .
74. The swinging arms 73 and 74 are swingably attached to the frame 76 via the pivot shaft 75.

A pulse motor 77 is attached to one swing arm 73, and the pulse motor 77 rotates the upper roller 72 via pulleys 78, 79 and a belt 80.

In addition, a solenoid 82 is installed inside the frame 76 via a bracket 81, and the solenoid 82 is turned on.
In this state, the arm 73 is urged downward via the first coil spring 83. Further, in the OFF state, the second coil spring 84 urges the arm 73 upward. Therefore, when setting the magazine 85 to the draw-out position, the solenoid 82 is turned off and the pull-out roller pair 7I
Release the nip and set the leading edge of the film 86A between the upper and lower rollers 72 and 87. After the magazine is set, the solenoid 82 is turned on and the pulse motor 77 is also rotated to transport the negative film 86 to the film carrier side.

[Effects of the Invention] As explained above, according to the present invention, a large number of magazines for storing film in rolls are provided, developed films are stored in these magazines, and the developed films are moved to the film drawer position by a moving belt. The film is set one by one, the leading edge of the film is pulled out from the magazine at the film drawer position, and work such as printing exposure and negative inspection is performed. After this work is completed, the film is sequentially stored in the empty magazine lined up on the second moving belt. Since the film is set in various devices through the magazine, the film is not directly touched by the hands (and dirt is prevented from adhering to it). This protects the film from being scratched when loading it into various devices.Furthermore, the leading edge of the film can be pulled out from the magazine and stored in an empty magazine after the work is completed. , film can be automatically set in a printer, etc., and printing exposure can be performed efficiently.Furthermore, since each magazine is lined up on an endless moving belt, the movement of the moving belt is easier. By setting the next magazine in the empty space, printing processing etc. can be performed almost continuously, improving efficiency.
