[Embodiments of the invention]

1 and 2 show a state in which a film supply magazine 10 according to this embodiment is set in a developing device 12. As shown in FIG.

As shown in FIG. 3, the magazine 10 has a box-shaped magazine body 14 that is open at the top.
A lid 16 is attached to this opening so that it can be opened and closed.

Inside the magazine body 14, a pair of intermediate walls 18 are erected at the center in the width direction, and elongated cartridge accommodating portions 20, 2 extend along the longitudinal direction inside the magazine body 14.
It is divided into 2. These cartridge storage parts 2
0 and 22 can accommodate a large number of film cartridges 24, and a portion of the photographed film 26 stored in these cartridges 24 protrudes from the cartridge 24 and has an adhesive tape attached to its tip. A thin-walled leader 30 is attached by 28.

This thin reader 30 has a cartridge housing section 20.
Since the films 26 protruding from the two cartridges 24 housed in and 22 are connected together, the thin leader 30 is placed on the intermediate wall 18.

Furthermore, as shown in FIG. 1, the cartridge accommodating sections 20 and 22 in the magazine 10 can accommodate a large number of cartridges 24 from the front end (right direction in FIG. 1) to the rear end. The thin-walled leaders 30 connected to the cartridges 24 are stacked on top of each other, but the front end of the cartridge accommodated in the front end is arranged so that the tip of the thin-walled leader 30 protrudes more than the next cartridge, and the cartridge placed further behind it is The 24 thin-walled leaders 30 are arranged so that their tips are sequentially retracted and housed.

An endless belt 36 is wound around gears (not shown) fixed to shafts 32 and 34 between the pair of intermediate walls 18. A claw 3 is attached to the outer periphery of this endless belt 36.
A plurality of holes 8 protrude at regular intervals, and correspond to through rectangular holes 40 drilled at regular intervals into the thin leader 30. 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 thin-walled leader 30 to the right in FIG. 1.

The shaft 34 is protruded into the cartridge accommodating section 20,
A gear 42 is fixed near the tip. This gear 42 corresponds to a rack 44. This rack 44 is fixed to the tip 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 projecting into the cartridge accommodating portion 20. A compression coil spring 52 is interposed between a ring 50 fixed to the intermediate portion of the rod 46 and the block 48, and biases the rack 44 in the direction of separating it from the gear 42 and moving it forward. ing.

Also, the tip of the rod 46 is attached to the cartridge housing section 2.
It protrudes into a small box 54 disposed within 0. The inside of this small box 54 is in a light-shielded state from the inside of the cartridge accommodating section 20. The bottom of this small box 54 is formed with a notch 56 and corresponds to a drive means 60 arranged on the protruding bracket 58 of the developing device 12.
This protruding bracket 58 protrudes from a bracket 57 fixed to the developing device 12.

A cam 66 is fixed to the output shaft 64 of a motor 62 in the drive means 60 . This cam 66 has one end that corresponds to an intermediate roller 72 of an arm 70 that is pivotally supported on the protruding bracket 58 by a pin 68, and is adapted 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 inserts the small box 54.
It is designed to be inserted inside.

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 the motor 62 causes the cam 66 to rotate once. By applying a compressive force to the rod 46 and rotating the gear 42 by a predetermined angle clockwise in FIG. 1, each thin-walled leader 30 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, and the rod 46 returns to the state shown in FIG. 1 by the biasing force of the compression coil spring 52. To prevent the gear 42 from reversing the endless belt 36 during this return, the gear 42 is
A one-way clutch (not shown) is built in between the shaft 34 and the shaft 34.

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

This moderation mechanism 81 is a disk 8 fixed to the shaft 34.
Recesses 85A are formed at regular intervals on the outer periphery of the arm 86, and the rollers 86A of the arm 86 correspond to the recesses 85A.
This arm 86 is pivotally supported at one end by a pin 86B,
The other end is biased by a tension coil spring 87 and the roller 8
6A is pushed into the recess 85A.

The distance between the concave portions 85A is the same as the distance between the front and rear of the cartridge 24 stored in the magazine 10, so that even if the endless belt 36 is fed somewhat inaccurately by the motor 62, the roller 86A does not move between the concave portions 85A.
By entering into A, the endless belt 36 can be stopped at an accurate position.

A pair of opening/closing plates 8 are provided at the front end of the magazine body 14, each corresponding to the cartridge housing sections 20 and 22.
2 is pivotally supported, and the biasing force of a torsion coil spring 84 generates a biasing force in a direction to close the front end of the magazine body 14.

A movable plate 90 is provided on the bracket 57 corresponding to the front end of the magazine 10 inserted into the guide tube 76 of the protruding bracket 58, as shown in FIG. 2, and guided by a pair of guide bars 88. The cartridge 24 sent into the protruding bracket 57 comes into contact with these movable plates 90, and the cartridge 24 is moved by the biasing force of the compression coil spring 92.
4 in the direction of the magazine 10.

When the cartridge 24 moves the movable plate 90 rightward in FIGS. 1 and 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 claws 108 similar to the endless belt 36 are protruded from the outer periphery at regular intervals. Therefore, when the endless belt 102 rotates, it engages with the rectangular through hole 40 of the thin-walled leader 30 and guides the thin-walled leader 30 between the feed rollers 110 and 112, 114.

The feed roller 110 is connected to the shaft 116 of the gear 104.
The feeding rollers 112, 11
4 contacts the outer periphery of the feed roller 110 and transfers the fed thin leader 30 to the feed roller 11.
The structure is such that it is fed into the developing device 12 while being sandwiched between the two. This shaft 116 is adapted to rotate in response to 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 disposed on both sides of the guide 118, and are adapted to cut the rear end of the film when the limit switch 94 is activated.

Inside the developing device 12, the tip of the thin leader 30 fed out in the horizontal direction from the feeding roller 110 is guided to a developing tank 126 by a winding roller 122 and a bending guide 124. In this developer tank 126, an engaging 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 the fixing stabilizing tank, the washing tank, and the drying device.

Incidentally, at the lower part of the brackets 57 and 58, a staggered chute 130 is provided, in which the lower end of the inclined plate 128 corresponds to the middle of the lower inclined plate 128, and the inclined directions are sequentially different. The cartridge 24 can be dropped after use. 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 sequentially accommodates a plurality of cartridges 24 to which thin-walled leaders 30 are attached in cartridge storage sections 20 and 22 with the lid 16 open. In this case, the thin-walled leader 30 fixed to the cartridge 24 that is sequentially stored in the rear of the cartridge 24 shown in FIG. It will be placed backwards. For this reason, the plurality of cartridges 24 to be accommodated are arranged such that the tips of their thin leaders 30 are retreated into the magazine 10 by the pitch of the cartridges 24 to be accommodated one after another.

After all the cartridges 24 are stored, the lid 16 is closed.
The magazine 10 is then inserted into the guide tube 76 of the developing device 12 as shown in FIG. 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 pin 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 cause each thin leader 30 to protrude toward the developing device 12 by a predetermined length. Therefore, the thin leader 30 at the tip
engages with the pawl 108 of the endless belt 102.

Endless belt 1 which is rotated in advance here
02 engages with the protruding thin-walled leader 30 and feeds this thin-walled leader 30 to the rollers 110 and 11.
2,114. Therefore, the thin leader 30 is fed into the developing device 12, and the cartridge 24 at the tip abuts against the opening/closing plate 82 to support the reaction force of drawing out the film. Therefore, the film 26 is guided by the thin leader 30 to the pyrone 2.
4 and sent into the developing device 12, where development proceeds.

When all the films 26 in the cartridge 24 are pulled out, the film 26 fixed to the reel shaft of the cartridge 24 pulls the cartridge 24, so the opening/closing plate 82 is opened against the urging force of the torsion coil spring 84, and the magazine 10 The cartridge 24 pulled out from inside comes into contact with the movable plate 90, and the opening/closing plate 82 is closed by the biasing force of the torsion coil spring 84. Furthermore, this cartridge 24 has a movable plate 90.
is moved toward the developing device 12 against the biasing force of the compression coil spring 92.

When the leader 30 is pulled by the driving force of the feed rollers 110, 112, 114, the cartridge 24 opens the opening/closing plate 82 and hits the moving plate 90.
The biasing forces of the torsion coil spring 84 and the compression coil spring 92 may be set so that the reaction force for pulling out the film during development is supported by the moving plate 90.

The limit switch 94 is actuated by this movement of the moving plate 90, and the cutter 120 cuts the film 26 near the end and transfers the film 26 to the cartridge 2.
Separate from 4. 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 are stored in the storage box through the staggered chute 130.

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.

In this way, 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. Just take it out and load the next magazine 10 into the guide tube 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 tilted to the guide tube 76.
However, the rest of the structure is the same as that of the previous embodiment, and the same function is achieved.

Further, in the present invention, the magazine 10 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 end with a guide plate or the like. As a result, the magazine 10 does not protrude in the lateral direction of the developing device 12, and the installation space can be reduced.

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