Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magazine for storing a cartridge and used in a film feeding device for feeding the film in the cartridge to a developing machine.

[Background Art] A film supply device has been proposed in which a thin leader is connected to the tip of the film protruding from a cartridge, and the leader is sequentially moved into each developing tank to pull out the film and automatically perform development. . According to this film supply device, an operator can automatically develop the film by simply connecting the leader with an adhesive tape or the like to the film whose leading end has been pulled out from the cartridge and setting it in the developing machine.

However, in such a developing machine, when all the films have been pulled out from the cartridge and development has been completed, the operator must again attach the leader to the next cartridge and set it in the developing machine. For this reason, although development is performed automatically, it is necessary to manually set the film into the developing machine, which causes a decrease in work efficiency.

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, it is an object of the present invention to provide a magazine for a film supply device that enables automatic development by setting a large number of films in a developing machine in advance.

[Summary and operation of the invention] The magazine for a film supply device according to the present invention is a magazine that accommodates a film winding cartridge in a magazine main body, is loaded into the film supply device, and delivers the leading end of the film to a developing machine. A cartridge accommodating portion provided in the magazine body to accommodate the cartridge so as to be movable by a predetermined stroke in the film extraction direction, a film outlet formed in the magazine body, and a leader provided in the film outlet and attached to the tip of the film. It has a clamping and guiding means that clamps and reliably delivers the leader tip protruding from the magazine body to the developing machine.

Therefore, in the magazine for a film feeder according to the present invention, when the operator stores the cartridge in the storage section and the leader attached to the leading end of the film is held by the holding and guiding means, the leader is accurately positioned and transferred to the developing machine. and can be delivered.

When the cartridge is housed in the magazine, the film in the cartridge will not be exposed inadvertently even if the inside of the magazine is not light-shielded. When the reader is pulled out after the magazine is connected to the developing machine and the film ejection port is securely shielded from light, the cartridge moves with the leader to the stroke end, and then the tension of the leader pulls out the film from the cartridge, and the film is It is sent to the developing machine in a light-blocked state.

[Embodiments of the Invention] Figs. 1 and 2 show a film feeding device used to feed film to a developing machine P, and a frame-shaped stand 10 serving as a storage means is attached to a machine base 1.
The stand 10 is erected from 1 and is shown loaded with a large number of magazines 12.

Details of the magazine 12 are shown in FIGS. 3 and 4, and the magazine body 14 is formed into a box shape with an open top, and a cover is pivotally supported at one end by a hinge 15 (see FIG. 1). 16 allows the inside of the magazine body 14 to be opened and closed. This cover 1
An arm 18 protruding from near the tip of the magazine 6 is engaged with a click 20 provided on the magazine body 14 when the cover 16 is closed, thereby maintaining the closed state.

The inside of the magazine body 14 is a cartridge housing section 2.
In this embodiment, a pair of cartridges 24 can be accommodated. A rib 26 along the longitudinal direction of the magazine body 14 is formed on the bottom surface of the cartridge accommodating portion 22 between these cartridges 24.
movement in the width direction is restricted to prevent them from interfering with each other.

In addition, as shown in FIG.
The cartridge 24 housed in one end of the magazine body 14 is movable in the direction of a film outlet 28, which is an opening formed at the other end of the magazine body 14, until it comes into contact with the front end wall 14A.

A negative film 30, most of which is stored in a reel 25 in a cartridge 24, is attached to a thin flexible leader 34 by an adhesive tape 32 at its leading end.
is installed. This leader 34 has a width dimension that allows two negative films 30 to be connected in parallel using an adhesive tape 32, and its longitudinal dimension is as shown in FIG.
Even when the tip 34A is placed at the end of the cartridge accommodating portion 22, the tip 34A is not connected to the film outlet 28.
It is long enough to protrude from the top.

A felt 36 is installed around the opening of the film outlet 28 as a clamping guide means.
As a result, the felt 36 tightly clamps the leader 34 and positions the leader tip 34A in a fixed position.
This ensures reliable delivery to the developing machine P.

A rack 38 is provided on the side surface of the magazine body 14 with a plurality of protrusions extending perpendicularly to the longitudinal direction of the magazine body and arranged parallel to each other. These racks 38 are adapted to mesh with a worm gear 40 which is pivotally supported on the machine base 11 as shown in FIGS. 2 and 5. A small gear 42 is coaxially fixed to this worm gear 40, and meshes with a large gear 44. This large gear 44 is fixed to an output shaft 48 of a motor 46.

Therefore, the motor 46 is connected to the worm gear 40 during operation.
rotate the magazine body 1 through the rack 38.
4 to the film intake section 52 of the film developing machine P. The combination of the rack 38 and the worm gear 40 also constitutes a part of ejecting means for extracting the magazine 12 from the intake portion 52 by reversing the motor 46 when the film supply from the magazine 12 is completed.

The engagement between the worm gear 40 and the rack 38 generates a driving force that presses the bottom surface of the magazine body 14 against the support base 54 when the magazine body 14 moves in the direction of the film intake section 52 of the developing machine P. It is preferred that the protrusions of the rack 38 are arranged vertically or inclinedly for this purpose.

The support base 54 is the lowest magazine body 14 among the plurality of magazines 12 loaded into the stand 10.
This lowermost magazine body 14
It is designed to constitute a guide surface that slides when the film is moved in the direction of the film intake section 52. A rack 56 is fixed to the abutment 54 on the opposite side of the contact surface with the magazine body 14, that is, on the lower surface thereof, and is engaged with a spur gear 58. This spur gear 5
8 rotates under the driving force of the motor 60, and the supporting base 5
4 can be retracted from the state shown in FIG. 1 to the state shown in FIG.

As shown in FIG. 5, receiving pins 62 are coaxially screwed into the inner wall of the stand 10 and are arranged facing each other. These receiving pins 62 are attached to the magazine main body 14 located at the bottom layer.
This corresponds to the width direction protrusion 64 formed on the cover 16 of. That is, the receiving pin 62 is attached to the support base 54 when the magazine body 14 falls inside the magazine body 14.
The widthwise protruding portion 64 is supported in a state in which it is in contact with the support base 54, and the right-hand end portion of the magazine body 14 in FIG. When the magazine body 14 moves rightward in FIG. 1 by the driving force of the motor 60, this receiving pin 62 fits into the magazine body tip intake portion 66 formed in the film intake portion 52 as shown in FIG. The length is such that it supports the magazine 12 until just before it.
When the distal end of the magazine main body 14 reaches the support end 66A of the magazine main body distal end receiving portion 66, the end 64A of the width direction protrusion 64 comes off from the receiving pin 62.

In the film intake section 52, the tip of a stopper 68 projects into the magazine main body tip receiving section 66. This stopper 68 is pivotally supported by a pin 70 to the frame 72 of the film intake section 52, and is inserted into the magazine main body distal end receiving section 66 through a notch opening 74 at the distal end of the magazine main body 14 (see FIG. 4).
It enters from the inside and is arranged in the cartridge accommodating section 22.

To explain this stopper 68 in more detail, as shown in FIG.
When the stopper 68 is fitted into the magazine body tip receiving portion 66, the stopper 68 receives the urging force of the tension coil spring 76 interposed between the frame 72 and the stopper 68 in the direction of entering into the cartridge housing portion 22. There is. However, Patrone 2 up to the imaginary line state in Figure 6
4 moves, it rotates around the pin 70 in the direction of being ejected from the cartridge accommodating portion 22 against the biasing force of the tension coil spring 76.

When the stopper 68 is rotated in this manner, the limit switch 78 attached to the frame 72
detects the rotational state of the stopper 68 and sends a detection signal to a control device (not shown), so that the control device can determine the film end state.
A conveyance roller 80 is pivotally supported within the film intake section 52, and a plurality of pressing rollers 82 abut against the conveyance roller 80 with force. These pressing rollers 82 are connected to the film intake section 5.
It is attached to the lid 84 of No. 2, and is separated from the conveying roller 80 when the lid 84 is opened and the light shielding inside the film intake section 52 is released.

As shown in FIG. 6, when the magazine body 14 is connected to the film intake section 52, the leader 3 protrudes from the film outlet 28 of the magazine body 14.
4 is held between a pressure roller 82 and a conveyance roller 80, and is sent out toward the developing machine P by the rotational force of the conveyance roller 80.

A cutter 88 is provided in the film intake section 52 between the conveyance roller 80 and the magazine main body leading end receiving section 66, and a cutter 88 is provided between the conveyance roller 80 and the magazine main body leading end receiving section 66.
It is possible to move both inside and outside of the movement trajectory. This cutter 88 is retracted out of the movement trajectory when the leader 34 and the negative film 30 are being conveyed, but when the limit switch 78 detects the rotating state of the stopper 68, it receives the driving force of the solenoid 89 and moves into the movement trajectory of the negative film 30. It moves to cut the negative film 30 near the end, and most of the negative film 30 that has reached the developing machine P is cut from the end of the negative film in the cartridge 24.

A discharge path 90 for the magazine 12 is provided between the film intake section 52 and the support 54.
The magazine 12 is guided by a bent portion 54A and a chute 92 formed at the tip of the magazine 12 to be dropped.

Next, the operation of this embodiment will be explained.

As shown in FIG. 4, the plurality of magazines 12 accommodate cartridges 24 each having a leader 34 attached to the tip of a negative film 30 with an adhesive tape 32, with the cover 16 open. A plurality of pieces are loaded into the stand 10.

In this state, light enters into the magazine 12 from the outside through the film outlet 28, but the part where the image of the film 30 is taken is the cartridge 2.
4, so there is no chance of inadvertent exposure. Therefore, an arbitrary number of additional magazines 12 can be loaded into the stand 10 at any time if necessary.

In this loaded state, the support base 54 is placed close to the film intake section 52, as shown in FIG.
is supported by the support base 54, and the widthwise protrusion 64 comes into contact with the receiving pin 62, so that it is housed in the stand 10 in the horizontal state shown in FIG.

Next, the motor 46 drives the rack 38 via the worm gear 40, so that the lowermost magazine 12
moves to the right in Figure 1. During this rightward movement, the distal end of the magazine 12 is gradually pushed out from the support 54 , and its own weight generates a force that forces the distal end downward. Because they are in contact, magazine 1
2, the leading end thereof is accurately delivered to the leading end receiving portion 66 of the magazine main body.

When the magazine 12 is fitted into the magazine main body tip receiving portion 66 as shown in FIG.
operation stops. When the magazine 12 is fitted into the magazine main body tip receiving portion 66 in this way,
The leader 34 protruding from the film outlet 28 of the magazine 12 is connected to the conveying roller 80 and the pressing roller 8.
It is inserted between 2 and 2.

The conveying roller 80 is driven and rotated in advance before the magazine body 14 is fitted into the magazine body leading end receiving portion 66, and the conveyance roller 80 is driven to rotate before the magazine body 14 is fitted into the magazine body leading end receiving portion 66.
send it off to When the front end of the magazine body 14 is fitted into the magazine main body front end receiving part 66 in this way, the front end notch 74 formed at the front end of the magazine main body 14 is shielded from light by the magazine main body front end receiving part 66. Therefore, the inside of the magazine main body 14 is maintained in a light-shielded state, and the film 30 is removed from the cartridge 24.
Even if it is pulled out, it will not be inadvertently exposed.

When the leader 34 is pulled in the direction of the developing machine P by the driving force of the conveying roller 80, the cartridge 24 receives this pulling force and moves rightward within the cartridge storage section 22 from the solid line state in FIG. The moved cartridge 24 comes into contact with the stopper 68, but the force is not strong enough to move the stopper 68 against the biasing force of the tension coil spring 76, and the cartridge 24 comes into contact with the stopper 68 and stops. As a result, the image capturing portions of the negative films 30 housed in the cartridge 24 are sequentially pulled out and conveyed to the developing machine P, where they are developed.

When the negative film 30 wound in layers on the reel 25 in the cartridge 24 is completely unloaded, the cartridge 24 is moved with a large force by the driving force of the transport roller 80 via the reel 25. It will be pulled in the direction of the intake part 52. Therefore, the cartridge 24 rotates the stopper 68 clockwise in FIG. 6 around the pin 70 against the biasing force of the tension coil spring 76.

Therefore, the stopper 8 operates the limit switch 78, and the limit switch 78 excites the solenoid 89 via a control device (not shown). Therefore, cutter 88 is negative film 30
enters the moving trajectory and cuts the negative film 30. As a result, the photographed portion of the negative film 30 that has reached the inside of the developing machine P and the cartridge 24
The end, which is locked to the inner reel 25, is cut off.

Here, the control device reverses the motor 46, returns the magazine 12 by a slight amount, and extracts the leading end from the magazine main body leading end receiving portion 66, resulting in the state shown in solid line in FIG. At the same time, the spur gear 58 of the motor 60 is driven, so that the abutment 54 is retracted in a direction away from the film intake section 52 and reaches the state shown by the solid line in FIG.
As a result, the magazine 12 loses its support and the ejection section 90
Fall inwards. At the time of this fall, the width direction protrusion 64 is already located at a position that does not correspond to the receiving pin 62, so the receiving pin 62 does not interfere with the falling operation of the magazine 12.

When the lowest magazine 12 is dropped on the chute 92, the next magazine 12 is dropped to the lowest level, and the above operation is repeated.

Next, FIGS. 9 and 10 show a film feeding apparatus to which a second embodiment of the present invention is applied.

In this embodiment, a rack 94 is formed in the longitudinal direction of the bottom surface of the magazine body 14, and is engaged with a spur gear 98 that partially projects from a support 96. This spur gear 98 is rotated by the driving force of a motor 99. This support 96 is pivotally supported by a hinge 100 to the frame 72 of the film intake section 52, and a drive shaft 102 is pivotally supported near the tip. This drive shaft 102 can rotate around a hinge 100 by receiving the driving force of a solenoid 104 attached to the machine base 11. Instead of this solenoid 104, a motor with a linear motion mechanism such as a motor with a linear head may be used.

Therefore, in this embodiment, when moving the magazine 12 in the direction of the film intake section 52, the motor 9
9 causes the spur gear 98 to drive the magazine 12 through the rack 94 toward the film intake section 52 and to fit it into the magazine main body leading end receiving section 66, thereby enabling the negative film 30 to be fed out.

Further, when the feeding of the negative film 30 is finished, the magazine 12 is pulled out from the magazine main body tip receiving part 66 by the reverse rotation of the motor 99, and the magazine 12 is removed from the 10th
As shown in the figure, the solenoid 104 is driven to tilt the support base 96, and the magazine 12 is dropped and discharged on the support base 96 by the reverse rotation of the motor 99.

Next, FIGS. 11 and 12 show a film feeding apparatus to which a third embodiment of the present invention is applied.

In this embodiment, the width direction protrusion 6 of the magazine 12
4 is formed over the entire length of the magazine 12, and a notch 110 is formed in the middle part. Further, the base of a leaf spring 112 is engaged with the widthwise protruding portion 64 adjacent to the film intake portion 52 side of the notch 110, and the intermediate portion of the leaf spring 112 is inclined and disposed below the notch 110. The notch 110 is arranged in a direction that gradually moves away from the notch 110 toward the distal end.

Therefore, in this embodiment, the lowest magazine 1
2 moves toward the film intake section 52, the receiving pin 62 elastically deforms the leaf spring 112 to enable the magazine 12 to move toward the right in FIG. When pulled out from the tip receiving portion 66 and returned, the receiving pin 62 enters above the leaf spring 112 and corresponds to the notch 110.

Furthermore, in this embodiment, even when the protruding amount of the magazine 12 from the support base 54 is large, the distal end of the magazine 12 is reliably supported and the distal end of the magazine 12 is prevented from accidentally entering the ejection path 90. We are guiding you.

Further, in this embodiment, a light shielding plate 114 is pivotally supported by the magazine tip receiving portion 66. This light shielding plate 11
When the magazine 12 is unloaded, the magazine 12 closes the entrance opening of the magazine tip receiving section 66 with its own weight to prevent light from entering the film intake section 52.
2 is pushed up by the magazine tip to open the magazine tip receiving section 66.

Note that the present invention is not limited to the ejection structure shown in the above embodiment, and other structures such as ejecting the lowermost magazine 12 to the left in FIG. 1 can also be applied. In addition, by maintaining the entire magazine loading stand 10 in a light-shielded state, the magazine 1
2 and the film intake portion 52 can be omitted.
