〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view showing a magazine according to the present invention.

The magazine 10 has a rectangular shape as a whole, and the magazine body 11 includes a storage section 14 for storing the negative film 12 in a roll shape, and a film passage 15 for introducing the negative film 12 into the storage section 14. is formed.

The storage section 14 is composed of a cylindrical cavity. The film passage 15 is formed tangentially to the peripheral wall of the storage section 14. In addition, a cover plate 17 is attached to the magazine body 11 so as to cover the storage section 14 and the passage 15.
It is attached via 8 so that it can be opened and closed freely. The cover plate 17 is
It is biased in the closing direction by a torsion spring 20. Also,
A recess 21 is formed on both sides of the lower part of the magazine body 11, and a locking portion 22 protruding from the center of the recess 21 is formed to lock a magazine set member 60, 80, which will be described later.

As shown in FIG. 2, a film feeding device 24 is used to store the developed negative film 12 in the magazine guide. This film feeding device 24 is
A pair of feed rollers 25 is provided. The lower roller 26 of the feed roller pair 25 is rotated by a pulse motor 28 via a timing belt 27, and feeds the negative film 12 into the storage section 14. The negative film 12 is stored in the storage section 14
When the film is almost stored in the magazine 10, the trailing end or the leading end of the film leaves the feed roller pair 25, so the film feeding is stopped and the film storage ends with the film end 12A slightly protruding from the magazine 10.

Next, a feeding device that uses the magazine 10 of the present invention to feed the negative film 12 to the exposure position of the printer will be described.

As shown in FIG. 3, a film carrier 32 is set in the center of a workbench 30 of the film feeding device. For example, a light source section of a printer is disposed below the film carrier 32, and a printing and exposure section (both not shown) is disposed above the film carrier 32.

On the workbench 10 on the film inlet side of the film carrier 32, there is an endless belt 36 for supplying film on which a large number of real magazines 10 are placed side by side in a horizontal direction, and an endless belt 36 for supplying film is set at the film extraction position of this supply side belt 36. A film pull-out means 38 is provided for pulling out the negative film 12 from the real magazine 10. Further, on the workbench 30 on the film exit side of the film carrier 32, there is an endless belt 40 on the film recovery side provided parallel to the supply side belt 36, and a film exit position of the film carrier 32 on the recovery side belt 40. A film storage means 39 for feeding the negative film 12 into the empty magazine IOA set in is disposed.

The moving belts 36, 40 on the supply side and the recovery side have a length that allows a large number of magazines 1O to be placed side by side in the horizontal direction, and are stretched horizontally between rollers 41, 42 and 43, 44. Each of these moving belts 36, 40 is rotated by pulse motors 45, 46. Also, on both sides of each moving belt 36,40 there is a magazine 10.4 on the belt.
Magazine guide 48 to prevent IOA from falling out.
is installed. Furthermore, a tip guide 51 is attached to the side of the moving belt 36 where the film end 12A of the magazine 10 is located, for guiding the film end 12A to the gap between the pair of pull-out rollers 50 of the film pull-out means 38. .

The tip guide 51 is connected to the lower guide 5 as shown in FIG.
2 and an upper guide plate 53. A gap is formed between each of these guide plates 52 and 53,
The film leading end 12A moves within this gap. The upper guide plate 53 is attached to the lower guide plate 52 so as to open upward, and the actual magazine 10 is attached to the moving belt 36.
When setting the film, the upper guide plate 53 is opened upward and the film end 12A is set.

Further, a magazine detection sensor 55 for detecting the actual magazine 10 set in front of the film extracting means 38 is arranged within the film extracting means 38 . Although an optical sensor is used as the sensor 55, a limit switch may also be used. A magazine detection signal output from the sensor 55 is sent to a controller (not shown).

The controller 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. Then, based on the magazine detection signal, the controller stops the rotation of the pulse motor 45 of the moving belt 36, stops the actual magazine 15 at the film draw-out position, and causes the magazine setting means 60 to move the magazine 15 to the film draw-out position. Fix it.

As shown in FIG. 5, the magazine setting means 60 includes a lock lever 61 that locks onto the locking portion 22 of the magazine 10. As shown in FIG. The lock lever 61 is rotatably attached to a base 62, and is displaced by a solenoid 63 between a retracted position in which it is flipped upward and a locking position in which it is horizontal.

A lock lever 61 is attached to the plunger 64 of the solenoid 63.
A coil spring 65 is attached to urge the solenoid 63 downward, and when the solenoid 63 is turned off, the lock lever 61 is set to the locking position. Further, when the solenoid 63 is turned on, the lock lever 61 is lifted upward and set to the retracted position so that it does not become an obstacle to the movement of the magazine IO. The tip of the lock lever 61 is bifurcated, and the locking portion 22 of the magazine 10 is held between both sides by this tip.

The film drawing means 38 is constructed as shown in FIGS. 4 and 5. FIG. 5 shows a state in which the leading end 12A of the film of the actual magazine 10 is set on the pull-out roller pair 50 of the film pull-out means 38.

As mentioned above, since the film leading end 12A protrudes from the outer surface of the real magazine 10, when the real magazine 10 is set at the pull-out position, the film leading edge 12A will come into contact with the nip of the pull-out roller pair 50. It turns out. For this reason, when setting the actual magazine IO to the pull-out position, the controller releases the nip between the pull-out roller pair 50 and lifts the upper roller 67 upward.

The upper roller 67 is mounted on a pivot arm 68,69. The swing arms 68 and 69 are swingably attached to the frame 71 via a pivot shaft 70. A pulse motor 72 is attached to one swing arm 68, and the pulse motor 72 rotates the upper roller 67 via pulleys 73, 74 and a belt 75. Also,
A solenoid 77 is attached within the frame 71, and the solenoid 77 lifts the arm 68 upward when it is in the ON state. Further, in the OFF state, the arm 68 is biased in a direction to rotate downward by the torsion spring 78. - Therefore, when setting the magazine 10 to the pull-out position, the solenoid 77 is turned on to release the nip between the pull-out roller pair 50 and create a gap between the upper and lower rollers 72 and 79 for insertion of the film leading edge 12A. . After setting the magazine, the solenoid 77 is turned off and the pulse motor 72 also rotates to load the negative film 1.
2 is transferred to the exposure position of the film carrier 32. At this time, a screen detection sensor (not shown) of the film carrier 32 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 12, 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 39 has the same structure as the film feeding device 24 shown in FIG. 2, and its explanation will be omitted. Further, the collection side moving belt 40 and the magazine setting means 80 attached thereto are also constructed in the same manner as the film supply side moving belt 36 and the magazine setting means 60 described above, and the explanation thereof will be omitted.

A film detection sensor is arranged on the film exit side of the film carrier 32 to detect the film leading edge 12A. Based on the film leading edge detection signal from this sensor,
The controller rotates the motor of the film storage means 39 to feed the negative film 12 into the empty magazine IOA. Further, when the film detection sensor detects the film end signal, the controller rotates the motor of the film storage means 39 by a predetermined amount to transfer the negative film 12 to the empty magazine I.
After storing it in the OA, its rotation is stopped. At this time,
When the end of the negative film 12 leaves the pair of feed rollers of the film storage means 39, the negative film 12 is no longer fed into the empty magazine 10A, and the end of the negative film 12 slightly protrudes from the magazine 10. Stored in good condition.

Thereby, the negative film 12 can be easily pulled out from the magazine 10 when setting the magazine 10 in a negative cutter (not shown) for the next process.

After storing the negative film 12 in the magazine 10, the nip between the pair of drawing rollers of the film drawing means 3 is released, and the setting of the magazine setting means 60.degree. 80 is released. Then, each moving belt 36.40 is rotated,
Set the next magazine 10.1OA in each position.

Below is the first magazine 10. Similarly to IOA, the second
The negative film 12 is pulled out from the second real magazine IOA, and after the printing exposure of each screen, the negative film 12 is pulled out from the second empty magazine IOA.
stored inside. The new real magazine 10 is a moving belt 3
Since it is appropriately set on the magazine supply side of No. 6, printing processing can be performed continuously. In addition, empty magazines 10 accumulated on the outlet side of the magazine supply side moving belt 36
A is transferred to the film recovery side moving belt 40 as appropriate. Further, the magazine 10 containing the negative film 12 that has been subjected to printing exposure is appropriately taken out from the recovery side moving belt 40 and set in a negative cutter for the next process.

The above embodiment describes a feeding magazine for setting developed film at the exposure position of a printer, but it can also be used when transporting film for negative inspection or film cutting. The magazine of the present invention can also be used for.

Further, in the above embodiment, the rotation of each moving belt 36, 40 is controlled by the signal from the magazine detection sensor 55,
Each magazine 10. The IOA 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, and the magazine is moved to each position by this stopper. You can also set it.

〔Effect of the invention〕

4. As explained above, according to the present invention, a film storage section consisting of a cylindrical cavity is provided, and the film is inserted into this storage section so that the end of the film is aligned with the peripheral wall inside the storage section. , just feed the film into the storage compartment.
The film can be stored in a roll, and there is no need to provide a reel for winding up the film, making the configuration simple. Moreover, since the film is stored with the end of the film left protruding from the magazine, it becomes easy to pull out the film from the magazine, and it becomes possible to automate film feeding with a simple configuration. Further, since the film is stored in a storage section that is partitioned off from the outside, the film does not come into direct contact with the hands and can be prevented from being scratched or dusted. Furthermore, by providing a lid that can be opened and closed to cover the film passage and the side opening of the storage section, the film can be easily taken out of the storage section in its rolled form without having to pull the film out of the storage section.
