The present invention has been made in consideration of the above facts, and an object of the present invention is to obtain a film supply magazine that can automatically supply a large number of films to a developing device.

[Summary and operation of the invention]

The present invention is a film supply magazine in which a leader is attached to the leading end of the film protruding from a film storage container, and the film is fed into a developing device while being guided by the leader. A magazine body in which jX number of film storage containers are arranged one after the other, and leaders connected to the films of these storage containers are arranged one on top of the other so that the tip positions of the leaders are sequentially different; The magazine is characterized in that it includes a feeding means for sequentially protruding the plurality of leaders from the magazine main body.

For this reason, in the magazine of the present invention, when a large number of film storage containers are housed side by side in the magazine main body, the feeding means rotates and sequentially feeds the film storage containers from the leader at the front end to the developing device.

After the film in the first film storage container is developed, the next film storage container is sent from the magazine to the developing device by the feeding means and developed.

As a result, a large number of films stored in the magazine are sequentially developed, so that the operator only has to set the magazine containing a large number of films into the developing device (this greatly improves work efficiency).

(Embodiment of the invention) Figure 1.2 shows a film supply magazine l according to this embodiment.
A state in which O is set in the developing device 12 is shown.

As shown in FIG. 3, the magazine lO is a magazine body 14.
It has a box shape with an open top, and a lid 16 is attached to this opening so that it can be opened and closed.

Inside the magazine body 14, there is a pair of intermediate walls 1 at the center in the width direction.
8 are erected to partition the inside of the magazine body 14 into elongated cartridge accommodating portions 20 and 22 along the longitudinal direction. These cartridge storage sections 20122 can accommodate a large number of cartridges 24, which are film storage containers, and some of the exposed films 26 protrude from the cartridges 24 and are stored in these cartridges 24. A thin leader 30 is attached to the tip with adhesive tape 28.

Since the films 26 protruding from the two cartridges 24 accommodated in the cartridge accommodating portions 20 and 22 are connected to the thin leader 30, the thin leader 30 is placed on the intermediate wall 18. It has become.

Further, as shown in FIG. 1, a plurality of cartridges 24 are arranged at the front end (
Since a large number of cartridges can be accommodated from the right side in Fig. 1 to the rear end, the thin-walled leaders 30 connected to these cartridges 24 are stacked on top of each other, but the cartridges housed in the front end cannot be used for the next cartridge. Thinner leader than 3
The leading end of the cartridge 24 is arranged so that the leading end of the cartridge 24 protrudes, and the thin leader 30 of the cartridge 24 is located behind the leading end of the cartridge 24 so that the leading end thereof is sequentially retracted and accommodated.

An fi end belt 36 is wound around a gear (not shown) fixed to a shaft 32, 34 between the pair of intermediate walls.

A plurality of pawls 38 are protruded from the outer periphery of the endless belt 36 at regular intervals, and correspond to through rectangular holes 40 drilled into the thin leader 30 at regular intervals. The pawl 38 protrudes beyond the upper end of the intermediate wall 18 when rotated, and is rotated clockwise in FIG. 1. Therefore, during rotation, it has the role of sending out each three-bar leader 30 to the right in FIG.

The shaft 34 projects into the cartridge accommodating portion 20, and has a gear 42 fixed near its tip. This gear 42 corresponds to a rack 44. The rack 44 is fixed to the distal end of a rod 46, and the rod 46 is movable in the axial direction with its intermediate portion being pivotally supported by a block 48 protruding into the cartridge accommodating portion 20. A compression coil spring 52 is interposed between a ring 50 fixed to the middle portion of the rod 46 and the block 48, and a compression coil spring 52 is inserted between the rack 44 and the gear 42.
It is designed to be biased in the direction of moving it forward and away from it.

Further, the tip of the rod 46 protrudes into a small box 54 disposed within the cartridge accommodating section 20. The inside of this small box 54 is in a light-shielded state from the inside of the cartridge accommodating section 20. A notch 56 is formed at the bottom of the small box 54, and the developing device 1
The driving means 60 corresponds to the drive means 60 arranged on the protruding bracket 58 of No. 2.

This protruding bracket 58 protrudes from a bracket 57 fixed to the developing device 12.

A cam 66 to an output shaft 64 of a motor 62 is fixed to the drive means 60 . This cam 66 has a pin 68 at one end and corresponds to an intermediate roller 72 of an arm 70 that is pivotally supported on the protruding bracket 58, and is designed to reciprocate and rotate a roller 74 that is pivotally supported on the tip of the arm 70. There is.

The arm 70 passes through a notch 78 formed in a guide tube 76 that protrudes from the protruding bracket 58 for insertion of the magazine 10, passes through the notch 56 of the magazine body 14 inserted into the guide tube 76, and enters the small box 54. It is meant to be inserted.

Further, when the motor 62 is at the stop position, the arm 70 separates the roller 74 from the tip of the rod 46 by the biasing force of the tension coil spring 80, but when the cam 66 is rotated once by the motor 62, the rod Applying compressive force to 46,
By rotating the gear 42 by a predetermined angle clockwise in FIG. 1, each thin-walled leader 3° is moved rightward in FIG. 1 by a predetermined amount. Therefore, when the motor 62 rotates once, the roller 74 returns to its original position, so the rod 46
is returned to the state shown in FIG. 1 by the biasing force of the compression coil spring 52. In order to prevent the gear 42 from reversing the endless belt 36 during this return, a one-way clutch (not shown) is built in between the gear 42 and the shaft 34.

A moderation mechanism 81 shown in FIGS. 2 and 4 is provided to move the endless belt 36 accurately by a predetermined pitch and then stop it at a predetermined position when the motor 62 rotates.

This moderation mechanism 81 has recesses 85A formed at regular intervals on the outer periphery of a disk 85 fixed to the shaft 34, and the rollers 86A of the arm 86 correspond to the recesses 85A. One end of this arm 86 is pivotally supported by a pin 86B, and the other end is biased by a tension coil spring 87 to push the roller 86A into the recess 85A.

The distance between the recesses 85A is the same as the distance between the front and back of the cartridge 24 accommodated in the magazine 10, and the distance between the motor 6
Even if the feeding of the endless belt 36 by the roller 86A is somewhat inaccurate, the endless belt 36 can be stopped at an accurate position by the roller 86A entering the recess 85A.

A pair of opening/closing devices 82 corresponding to the cartridge housing portions 20 and 22 are pivotally supported at the front end of the magazine body 14, and the magazine body 1 is opened by the biasing force of a torsion coil spring 84.
A biasing force is generated in the direction of closing the front end of 4.

Corresponding to the front end of the magazine 10 inserted into the guide tube 76 of the protruding bracket 58, the bracket 57 has a movable plate 90 guided by a pair of guide bars 88 as shown in FIG.
is provided. The cartridge 24 sent into the protruding bracket 57 comes into contact with these movable plates 90, and the biasing force of the compression coil spring 92 generates a force that pushes the cartridge 24 back toward the magazine 10. .

When the cartridge 24 moves the movable plate 90 to the right in FIG. 1.2 against the biasing force of the compression coil spring 92, the limit switch 94 can detect this.

A small bracket 98 projects between the pair of guide bars 88 from an intermediate wall 96 that supports the ends of the pair of guide bars 88, and pivotally supports the gear 100. A portion of an endless belt 102 is wound around this gear 100.

This endless belt 102 is wound around gears 104 and 106 interposed between the gear 100 and the developing device 12, and has pawls 10B similar to the endless belt 36 at regular intervals on the outer circumference.
is prominent. For this reason, the endless belt 102 engages with the through rectangular hole 40 of the thin-walled leader 30 during rotation, and guides the thin-walled leader 30 between the feed rollers 110 and 112, 114.

The feed roller 110 is fixed to the shaft 116 of the gear 104, and the feed rollers 112 and 114 are in contact with the outer periphery of the feed roller 110, and the thin leader 30 that has been sent out is held between the feed roller 110 and the developing device. This configuration sends the data to 12. This shaft 116 is configured to rotate by receiving the driving force of a motor (not shown).

The endless belt 102 engages with the thin leader 30 between the gears 104 and 106 and moves in the horizontal direction, but the endless belt 102 moves horizontally so that the engaged thin leader 30 does not detach inadvertently. A guide 118 is provided correspondingly. As shown in FIG. 2, cutters 120 are arranged on both sides of this guide 118, and cut the rear end of the film when the limit switch 94 is activated.

Inside the developer W 12, the tip of the thin leader 30 fed out in the horizontal direction from the feed roller 110 is guided to the developer tank 126 by a winding roller 122 and a bending guide 124. In this developing tank 126, a holding means (not shown) for the thin leader 30 is arranged, and a driving force is applied to the thin leader 30 so that the thin leader 30 is sequentially sent to a washing tank, a fixing stabilizing tank, and a drying device.

Incidentally, at the lower part of the bracket 57.5, there is provided a staggered chute 130 in which the lower end of the inclined plate 128 corresponds to the middle of the lower inclined plate 128, and the inclined direction is different in sequence. Patrone 24 after use in storage box
It is possible to fall. This chute 130 opens the inside and outside of the protruding bracket 58, but can maintain a light shielding state.

Next, the operation of this embodiment will be explained.

As shown in FIG. 3, the magazine 10 is inserted into the cartridge accommodating portion 20, 22 with the thin-walled leader 30 with the lid 16 open.
A plurality of cartridges 24 with attached cartridges are sequentially accommodated. In this case, the thin leader 30 fixed to the cartridge 24 which is sequentially housed in the rear of the cartridge 24 shown in FIG. It will be placed backwards. Are you being detained for this? j!
A number of cartridges 24 are arranged in the magazine 10 by the pitch of the cartridges 24 in which the tips of the thin leaders 30 are successively accommodated.
It is placed retreating inward.

After all the cartridges 24 are stored, the magazine 1116 is closed and the magazine IO is transferred to the developing device 1 as shown in FIG.
2 into the guide tube 76. In this inserted state, the tip of the rod 46 is separated from the tip of the arm 70, and the gear 42 is not receiving any rotational force.

When the motor 62 is driven to rotate the cam 66 once, the arm 70 reciprocates once around the bin 68, causing the roller 74 to press the rod 46 to the left in FIG. 1 and return. Therefore, the rod 46 engages the rack 44 with the gear 42, rotates the endless belt 36 clockwise in FIG. 1 by a predetermined angle, and returns. As a result, the claws 38 of the endless belt 36
causes each of the three thin blades 7j-da to protrude by a predetermined length toward the developing device 120,000. Therefore, the thin leader 30 at the tip engages with the pawl 108 of the endless belt 102.

At this point, the endless belt 102 which is rotated for caulking engages with the protruding thin-walled leader 30, and the thin-walled leader 30
is held between the feed rollers 110 and 112 and 114. Therefore, the thinner 30 is fed into the developing device 12, and the leading end (C), O-, i, 24 comes into contact with the opening/closing plate 82 to support the reaction force of drawing out the film. Therefore, guided by this thin leader 30, the film 26 is pulled out from the cartridge 24 and sent into the developing device 12, where development proceeds.

When all the film 26 in the cartridge 24 is pulled out, the film 2 fixed to the reel shaft of the cartridge 24
6 pulls the cartridge 24, so the opening/closing plate 82 is opened against the biasing force of the torsion coil spring 84, and the magazine 1
The cartridge 24 pulled out from inside 0 comes into contact with the movable plate 9o, and the opening/closing plate 82 is closed by the biasing force of the torsion coil spring 84. The developing device 1 is moved against the biasing force of the compression coil spring 92.
Move in two directions.

When the leader 3o is pulled by the driving force of the feed rollers 110 and 112, 114, the opening/closing plate 8
The biasing forces of the torsion coil spring 84 and the compression coil spring 92 may be set so that the film pull-out reaction force during development is supported by the movable plate 90 when the torsion coil spring 84 and the compression coil spring 92 are released.

This movement of the moving plate 90 activates the limit switch 94, and the cutter 120 cuts the film 26 near the end to separate the film 26 from the cartridge 24. At the same time, the cartridge 24 whose tensile force has been released is pushed out to the left in FIG. and the movable plate 90, and fall through the staggered chute 130 to be stored in the storage box.

Thereafter, the motor 62 rotates once again and the cam 66 feeds out the next cartridge 24, so that the same operation as described above is repeated and the films in the magazine 10 are sequentially developed.

The operator does not need to perform any special operations until all the films 26 of the cartridge 24 stored in the magazine 10 are developed, and after all the films have been developed, the magazine 10 is removed from the guide tube 76. Take it out and
Just load the next magazine 10 into the guide cylinder 76.

Next, FIG. 5 shows a second embodiment of the present invention. In this embodiment, the guide cylinder 76 in the previous embodiment is attached to the developing device 12 not in a horizontal direction but in an inclined state. Accordingly, the magazine 10 is also inserted into the guide tube 76 in an inclined state, but the other configurations are the same as those of the previous embodiment and have the same effect.

Further, in the present invention, the magazine IO may be placed not only in an inclined position but also in a vertical position. That is, the magazine body 14 is arranged vertically with the opening/closing plate 82, which is the outlet of the magazine body 14, facing upward or downward. The leader 30 protruding from the magazine body 14 may be guided between the feed rollers 110 and 112 by bending the tip with a guide plate or the like.

As a result, the magazine IO does not protrude in the lateral direction of the developing device 12, and the installation space can be reduced.

In the above embodiment, an endless belt 36, a gear 42, a rod 46, etc. are used to sequentially feed out the cartridges 24 in the magazine 10, but other driving means such as directly rotating the shaft 34 by a motor (not shown) may be used. It is possible.

〔Effect of the invention〕

As explained above, the present invention is a film supply magazine in which a leader is attached to the leading end of a film protruding from a film storage container, and the film is fed into a developing device while being guided by the leader. A magazine body which is arranged one above the other so that the tips of the leaders which are housed in front and back and are connected to the films of these storage containers are sequentially aligned; Since it has a feeding means that protrudes from the main body, it has an excellent effect of automatically feeding a large number of films to the developing machine.
