Therefore, in the present invention, the cassettes each containing the film after shooting can be stacked and stored in the stock section, and the lowest cassette of the cassettes in this stock section is separated by the separating means, and after separation, The cassette is temporarily supported by the supporting means, and the feeding means connects the cassette to a processing device, and the film inside is fed into a processing device such as a developing device. After the film inside has been fed into the processing device, the feed means returns the cassette to the support means, the support means releases the support of the cassette, and the next cassette is transferred from the stock part to the support means in a common ratio. 1 (to be done)

In this way, by loading the photographed film into a cassette in advance and preparing a large number of cassettes, these films are automatically supplied to the processing device, so that automatic film supply is possible.

[Embodiments of the invention]

Figure 1.2 shows a film feeding device 1 to which the present invention is applied.
0 is shown. In this film supplying device 10, the lowest cassette 12 is separated from the stock section 14 in which a large number of cassettes 12 are stacked and stored, by the separating means 16 and supported by the supporting means 18j-, and then transferred to the processing device by the feeding means 20. The developing device ff22 is connected to the developing device ff22.

In the stator section 14, a vertical wall guide 24 covers the periphery of the stacked cassettes 12, and stacks a large number of cassettes 12 below -L.

FIG. 5 shows the cassette 1-12 used in this embodiment. The cassette body 26 of the cassette 12 is formed into a box shape, and a cartridge 28 and an inner magazine 30 can be housed inside.

As shown in FIG. 7, the inner magazine 30 includes a magazine main body 32, which is partially open and has a storage section inside which can store photographed film, and a magazine main body 32.
A cover plate 36 is pivotally supported by a hinge 34 to the open end of the cover plate 36 . A flange 38 is protruded from a part of the magazine body 32 so that when the cover brake 1/36 is brought into close contact with the magazine body 32, the interior of the magazine body 32 is shielded and a film outlet is formed. The cover plate 36 is tightly attached to the flange 38 of the magazine body 3 so that it is in the state shown in FIG.

It is preferable to attach felt or the like to the magazine body 32 and cover plate 36 to protect the film and prevent light reflection.

As shown in FIG. 5, the width of this inner magazine 300 is larger than the width of the cartridge 28, so that it can accommodate a film 44 wider than the film 42 accommodated in the cartridge 28. There is.

A thin leader 4B is connected to the tips of the films 42 and 44 protruding from the cartridge 28 and the inner magazine 30 by an adhesive tape 46, for example.

The thin leader 48 is a plate made of synthetic resin, and a perforation 50 is formed in the center along the longitudinal direction, and is used for league drive within the developing device 22.

The cassette main body 26 is provided with an opening/closing lid 52 that is hinged to a fixed lid 51 so that the inside can be opened, and after storing the cartridge 28 and the inner magazine 30, by closing this opening/closing 1i52, a thin-walled reader can be opened. 48 is adapted to protrude from the cassette 12.

Note that the hatched area in FIG. 6 indicates the fixed portion between the fixed lid 51 and the cassette body 26, and both ends of the fixed lid 51 protrude slightly from the cassette body 26.

Further, guide protrusions 26A, 26 are provided on the side of the cassette body 26.
B protrudes, and the space between these is for engagement with the feeding means 20.

In the separating means 16, a rotation block 56 is pivotally supported by support shafts 54 arranged in parallel to each other on both sides below the vertical wall guide 24. This rotation block 56 has a stopper plate 58.
are fixed to each other, and this stopper plate 58
The lower end portions of the two protrude toward each other to form a stopper piece 60. In other words, these stopper pieces 60 are arranged horizontally, and are adapted to support the lowermost cassette 12 of the stopper section 14 with its fixed lid 51 portion.

A roller 64 is supported by a pin 62 on the rotation block 56 with its axis perpendicular, and corresponds to the cam 66. This cam 66 is fixed to a rotary ring 68 whose axis is vertically supported. Among the rotating shafts 68 disposed on both sides of the stopper portion 14, a bevel gear 7 is disposed at an intermediate portion of one rotating shaft 68.
0.72, and this driving force is transmitted to the other rotating shaft via the pulley 75 and the endless helmet 75A that bypasses the stock portion 14. Further, a tension coil spring 76 (FIG. 4) is interposed in the rotation block 56 so that the roller 64 is always in contact with the outer periphery of the cam 66.

As shown in FIG. 4, the small radius part of the cam 66 corresponds to the roller 64 in the normal state, but when the motor 74 rotates, the large radius part of the cam 66 corresponds to the roller 64.
The rotation block 56 is rotated to move the stopper pieces 60 in directions away from each other. Therefore, in this state, the distance between the pair of stopper pieces 60 is smaller than that of the fixed lid 5.
1, and the lowest cassette 12 falls.

In order to prevent the fixed lid 5I of the next stage cassette 12 from falling in this state, a stopper piece 78 protrudes horizontally from the end opposite to the stopper piece 60 of the stopper plate 58. The protruding dimension of this stopper piece 7 is smaller than that of the stopper piece 60, and when the cam 06 returns to the state shown in FIG. When the distance between the stopper pieces 78 becomes larger than the distance between the fixed lids 51, the stopper pieces 78 fall, and the stopper pieces 60 stop the cassettes 12 at the bottom.
becomes.

In the support means 18, a pair of support shafts 80 are attached below the support shaft 54, and are parallel to the support shaft 54. A rotation block 82 is pivotally supported on each of these support shafts 80 . 11-shaped stopper plates 84 are fixed to the lower ends of these rotation blocks 82, respectively.
One side of these stopper plates 84 extends horizontally to form a stopper portion 86, which can receive and support the fixed lid 51 of the cassette 2 dropped from the separating means 16.

On the other hand, a roller 90 is pivotally supported on the upper part of the rotation block 82 by a pin 88 like the rotation block 56, and a cam 92 is supported by a pin 88.
It corresponds to This cam 92 is fixed to the rotating shaft 68 together with the cam 66, but its phase is different from that of the cam 66.

For this reason, when the motor 74 rotates, the cam 92 rotates the rotating block 82 to separate the stopper parts 86 from each other, releasing support for the spent force cellar 1-12 and allowing the chute 94'' to fall. .

The feeding means 20 is movable by being guided by a slide block 98 to guide bars 96 which are arranged on both sides of the chute 94 and have a longitudinal direction in the horizontal direction. A feed screw 100, which is supported in parallel with the guide bar 96, is threaded through the slide block 98. This feed screw 10
0 rotates by receiving the driving force of the motor 102.

Note that the driving force of this motor 102 is derived from one feed screw 10.
The driving force transmitted to the feed screw 100 is also transmitted to the other feed screw 100 via a transmission means such as a chino.

The slide block 98 has a feeding bin 104 whose longitudinal direction is perpendicular to the direction of movement of the slide block 98.
is passed through the feed bottle 104, and the bottle 10 is fixed to the slide block 98 into the long hole 106 formed in the feed bottle 104.
8 is passing through.

For this purpose, the feeding bin], 04 is the elongated hole 106 and the bin 108.
It is possible to move in the left-right direction in FIG. 2 by a stroke determined by .

The tip of the feed bottle 104 is placed within the falling trajectory of the cassette 12, and is inserted between the guide protrusions 26A and 26B of the cassette 12 supported by the support means 18.

Therefore, when the slide block 98 is moved along the feed screw 100 by the motor 102, the feed screw 100 can reciprocate the cassette 12 between it and the developer bag W22.

A notch 110 is formed in the middle of the feeding bin 04, into which a retaining protrusion 112 constituting another part of the stopper brake L84 in the support means 18 is inserted.

Therefore, when the rotating block 82 of the support means 18 rotates, the feeding bin 104 receives this rotational force and moves in directions away from each other, so that it does not interfere with the falling operation of the falling cassette 12.

The developing device 22 is provided with a cassette receiving section 114 into which the tip of the cassette 12 engages, and when the cassette 12 engages with the cassette receiving section 114, the thin leader 48 is received through the window 116, and the conveying roller 118 is inserted into the developing device 22. and 1.20
, ]22, and a thin-walled leader 48 is sandwiched and conveyed between them.

A cutter 124 is provided adjacent to the booklet set receiving part 1.14, and a cutter 124 is provided adjacent to the booklet set receiving part 1.14.
When each of the films 42 and bins 44 in 0 is pulled out to the end, the ends of these films 42 and bins 44 are cut.

This end detection is performed in the cassette receiving section 1 of this cassette 12.
14, the limit switch 1.2 is pushed into the notch 126 provided at the tip of the cassette body 26.
This configuration is detected in 8. This limit switch 12
8 is detected when the detection arm 130 is pushed into the notch 126 and the detection arm 130 is moved when the cartridge 28 or the inner magazine 30 is moved by the increased tension of the film 42 and the bottle 44. .

Next, the operation of this embodiment will be explained.

As shown in FIG. 5, a thin leader 48 is attached to the protruding tip of the film 42 housed in the cartridge 28. Further, a film 42 having a width dimension different from the general width dimension is housed in the inner magazine 30, and a part thereof is made to protrude and is similarly attached to the thin leader 48. The work of storing the film 42 into the inner magazine 30 is carried out by inserting the film 42 into the cover plates 1 and 3 via the hinge 34, as shown in FIG.
6 is rotated while resisting the biasing force of the torsion coil spring 40, and after storage, the cover plate 36 is brought into close contact with the magazine body 32 by the biasing force of the torsion coil spring 40, so that the internal film 42 may be inadvertently damaged. It is never exposed to light.

In this way, a large number of cassettes 12 containing cartridges 28 and inner magazines 30 are stacked and stored in the stock section 14.

The lowermost fixing M51 of this cassette 12 is locked to the stopper piece 60 of the separating means 16.

As the motor 74 rotates, the cam 66 rotates the rotation block 56 via the roller 64, so the stopper piece 60
The cassettes 12 are separated from each other and the lowest cassette 12 is dropped downward. At the same time, the stopper piece 78 is attached to the next fixed lid 51.
and temporarily hold it. Furthermore, the motor 74
When the rotating block 56 rotates, the rotating block 56 returns to the state shown in FIG. 2, so that the next stage cassette 12 is supported by the stopper piece 60.

On the other hand, the cassette 12 dropped from the separation means 16 is supported by the stopper portion 86 of the support means 18 and stopped. At the same time, the tip of the feed bottle 104 enters between the guide projections 26A and 26B of the cassette 12.

When the feed screw motor 102 rotates, the slide block 98 is moved toward the developing device 22 by the feed screw 1.00 and engages with the cassette receiving portion 114.

Therefore, the thin-walled leader 48 protruding from the cassette 12
is sandwiched between the conveyance roller 118 and the conveyance rollers 120 and 122 and receives the rotational force of the conveyance roller 118, and the developing device 2
Drawn into 2. Guided by this thin leader 48, the film 42 and pin 44 are developed in the developing device 22. When the ends of the film 42 and the pin 44 are pulled out from the cartridge 28 and the inner magazine 30, respectively, the limit switch 128 detects this and closes the cutter 12.
4 cut the ends of the films 42, 44 simultaneously or separately.

Thereafter, as the motor 102 reverses, the slide block 98 and the feed pin 104 return to the state shown in FIG. At the same time, the motor 74 further rotates, causing the cam 92 to rotate the rotation block 82. Therefore, the stopper part 8
6 and the feed pin 104 move out of the falling trajectory of the cassette 12, and the holding of the cassette I2 is released, so that the cassette 12 is dropped through the chute 94.

Thereafter, the rotation of the motor 74 causes the moving block 56 to rotate again to rotation 1, and the lowermost cassette 12 is dropped onto the support means 18. The subsequent steps are the same as described above.
