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 supply device for supplying 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 leading end 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, one worker 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, an operator must reattach the leader to the cartridge and set it in the developing machine. For this reason, although development is performed automatically, it is necessary to manually set the film in the developing machine, which causes a reduction in the working ratio.

In consideration of the above-mentioned facts, the present invention aims 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 a film supply device, and delivers the leading end of the film to a developing machine, A cartridge accommodating part provided in the magazine body to accommodate the cartridge, a film ejection port formed in the magazine main body, and a leader tip provided in the film ejection port and protruding from the magazine main body while holding a leader attached to the film tip. and a clamping guide means for reliably delivering the part to the developing machine.

Therefore, the film supply according to the present invention? In the case of a magazine for carrying a film, if the operator stores the patrone in the storage section and causes the leader attached to the leading edge of the film to be held by the holding and guiding means, the leader can be accurately positioned and delivered to the developing machine.

[Embodiments of the Invention] Fig. 1.2 shows a film supply device used for supplying film to a developing machine P, in which a frame-shaped stand 10 serving as a storage means is erected from a machine stand 11. This stand IO is shown loaded with a multi-l1cv-y magazine 12.

FIG. 3.4 shows details of the magazine 12, and the magazine body 14 is formed into a box shape with an open top, and a cover 16 is pivotally supported at one end by a hinge 15 (see FIG. 1). allows the inside of the magazine body 14 to be opened and closed. An arm 18 protruding from near the tip of the cover 16 is engaged with a click 20 provided on the magazine body 14 when the cover 16 is closed, thereby maintaining the closed state.

The interior of the magazine main body 14 is a cartridge accommodating section 22, which can accommodate a pair of cartridges 24 in this embodiment. Between these cartridges 24, ribs 26 are formed on the bottom surface of the cartridge storage section 22 along the longitudinal direction of the magazine body 14, and restrict the movement of the pair of cartridges 24 in the width direction so that they do not interfere with each other. That's what I do.

Further, as shown in FIG. 4, the cartridge 24 housed in one end of the cartridge accommodating section 22 is movable in the direction of the 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. It becomes.

The negative film 30, most of which is accommodated in the glue 25 in the cartridge 24, is pulled out and attached to the adhesive tape 3.
A thin flexible leader 34 is attached by 2.

This leader 34 has a width that allows two pieces of negative film 30 to be connected in parallel using adhesive tape 32.
Further, its longitudinal dimension is such that the tip portion 34A can protrude from the film outlet 28 even when the cartridge 24 is placed at the end of the cartridge accommodating portion 22, as shown in FIG.

A felt 36 as a clamping and guiding means is implanted at the periphery of the opening of the film outlet 28, so that 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 formed on the side surface of the magazine body 14 by a plurality of protrusions extending perpendicularly to the longitudinal direction of the magazine body and arranged parallel to each other. These racks 38 are attached to the machine base 11 as shown in FIGS. 2 and 5.
It is designed to mesh with a worm gear 40 that is pivotally supported. 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 constitutes a magazine drive means that rotates the worm gear 4° during operation and sends out the magazine body 14 to the film intake section 52 of the film developing machine P via the rack 38. Furthermore, this combination of the rack 38 and the worm gear 40 is such that when the film supply from the magazine 12 is finished, the motor 46 is reversely rotated, and the magazine 1
2 from the intake portion 52.

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 and sends it out when the magazine body 14 moves in the direction of the film intake section 52 of the developing RP. is preferable,
For this reason, the plurality of protrusions of the rack 38 are arranged 2 at an angle from the vertical plane.

The support base 54 comes into contact with the bottom surface of the lowermost magazine body 14 of the plurality of magazines 12 loaded into the stand 10, and this lowermost magazine body 14 is connected to the film intake section 52.
It forms a guide surface that slides when moved in the direction. A rack 56 is fixed to the support base 54 on the opposite side of the contact surface with the magazine main body 14, that is, on the lower surface thereof, and meshes with a spur gear 58. This spur gear 5
8 rotates in response to the driving force of the motor 60, so that the support base 54 can be retracted from the state shown in FIG. 1 to the state shown in FIG.

As shown in FIG. 5, on the inner wall of the stand 10, pins 62 are coaxially disposed and are screwed into pins 62, which are disposed facing each other. The pins 62 of these receivers correspond to the widthwise protrusions 64 formed on the cover 16 of the magazine body 14 disposed at the lowest level. In other words, the receiver is pin 62
The magazine body 14 falls inside the magazine body 14 and supports the width direction protrusion 64 in a state where it comes into contact with the abutment 54, and the right end of the magazine body 14 in the figure 1 is unnecessarily attached to the abutment 54.
It is restricted so that it does not go below 4.

In addition, the pin 62 of this receiver is connected to the magazine body 14 by the motor 60.
It moves to the right in FIG. 1 by the driving force of , and has a length that supports the magazine 12 until just before it is fitted into the magazine main body tip receiving section 66 formed in the film intake section 52 as shown in FIG. 6. .

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 6 of the width direction protrusion 64
The receiver 4A can be removed from the pin 62.

In the film intake section 52, the magazine main body tip receiving section 66
The tip of the stopper 68 projects inward. 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 body 14's front end notch opening 74 (
(see FIG. 4) and is arranged in the cartridge accommodating section 22.

To explain this stopper 68 in more detail, as shown in FIG. The biasing force of the spring 76 is applied in the direction of entering the cartridge accommodating portion 22. However, when the cartridge 24 moves to the state shown in the imaginary line in FIG. 6, it rotates around the pin 70 in a direction in which it is ejected from the cartridge storage section 22 against the biasing force of the tension coil spring 76.

When the stopper 68 is rotated in this way, the frame 7
A limit switch 78 attached to the film intake section 52 detects the rotating state of the stopper 68. A conveyance roller 80 is pivotally supported within the film intake section 52, and a plurality of suppression rollers 82 are attached to the conveyance roller 80. They are now facing each other with force. These suppression rollers 82 are attached to a lid 84 of the film intake section 52, and are separated from the conveyance 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 34 protruding from the film outlet 28 of the magazine body 14 is held between the pressure roller 82 and the conveyance roller 80, and the leader 34 is held between the pressure roller 82 and the conveyance roller 80. It is configured to receive a rotational force from 80 and be sent out in the direction of the developing machine P.

A cutter 88 is provided in the film intake section 52 between the conveyance roller 80 and the magazine main body tip receiving section 66.
The reader 34 and the negative film 30 are movable both inside and outside of the movement locus. This cutter 88 is the leader 3
4 and the negative film 30, the IJ is placed outside the movement trajectory.
! However, the limit switch 78 suddenly
8 is detected, it receives the driving force of the solenoid 89 and moves into the movement trajectory of the negative film 30, cuts the vicinity of the end of the negative film 30, and cuts most of the negative film 30 that has reached the developing @P. The negative film inside the cartridge 24 is cut from the end.

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

Next, the operation of this embodiment will be explained.

A plurality of magazines 12 are covered with covers as shown in FIG.
With the cartridges 16 opened, cartridges 24 each having a leader 34 attached to the leading end of a negative film 30 with an adhesive tape 32 are accommodated, and a plurality of magazine bodies 14 are loaded into the stand 10.

Although light enters the magazine 12 from the outside through the film outlet 28 in this 7m length, the part of the film 30 where the image is taken is housed in the cartridge 24, so it will not be exposed inadvertently. Therefore, an arbitrary number of magazines 12 can be additionally loaded into the stand 10 at any time if necessary.

In this loaded state, the support stand 54 is placed close to the film intake section 52, as shown in FIG. 1, and the loaded magazine body 14 is supported by the support stand 54. Since the widthwise protruding portion 64 contacts the pin 62, it is housed in the stand 10 in the horizontal state shown in FIG.

Next, the motor 46 is connected to the rack 38 via the worm gear 40.
In order to drive the magazine 12, the lowest magazine 12 moves to the right in FIG. During this rightward movement, the leading end of the magazine 12 is gradually pushed out from the support base 54, and its own weight generates a force that pushes the leading end downward. Since they are in contact with each other, the leading end of the magazine 12 is accurately transferred to the leading end receiving portion 66 of the magazine body.

As shown in FIG. 6, when the magazine 12 is fitted into the magazine main body tip receiving portion 66, the operation of the motor 46 is stopped. In this state, the magazine 12 is fitted into the magazine main body tip receiving portion 66.

The leader 34 protruding from the film outlet 28 of the magazine 12 is inserted between the conveying roller 80 and the pressing roller 82.

This conveyance roller 80 is driven and rotated in advance before the magazine body 14 is fitted into the magazine body tip receiving portion 66, and feeds the leader 34 to the developing JaP. When fitted into the leading end receiving portion 66, the leading end notch 74 formed at the leading end of the magazine body 14 is fitted into the leading end receiving portion 66 of the magazine body 14.
6, the interior of the magazine body 14 is maintained in a light-shielded state, and even if the film 30 is pulled out from the cartridge 24, it will not be exposed inadvertently.

When the leader 34 is pulled in the direction of the developing machine P by the driving force of the transport roller 80, the cartridge 24 receives this pulling force and is retracted from the solid line state in FIG.

Move inside the container 22 to the right. This moved cartridge 24 comes into contact with the stopper 68, but the tension coil spring 76
The cartridge 24 is not large enough to generate a force that moves the stopper 68 against the urging force of the cartridge 24, and the cartridge 24 comes into contact with the stopper 68 and stops. As a result, the image capturing portions of the negative film 30 housed in the cartridge 24 are sequentially pulled out and conveyed to the developing machine P, where they are subjected to development processing.

When the negative film 30 wound in layers on the reel 25 inside the cartridge 24 has all the imaged parts pulled out, the driving force of the transport roller 80 moves the cartridge 24 through the reel 25 with a large force to the film intake section. It will be pulled in 52 directions. For this reason, the cartridge 24 pulls the stopper 68 against the urging force of the tension coil spring 76 so that the pin 70
Rotate clockwise as shown in Figure 6.

Therefore, the stopper 68 operates the limit switch 78, and the limit switch 78 excites the solenoid 89 via a control device (not shown). Therefore, the cutter 88 enters the movement trajectory of the negative film 30,
Cut 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 tail end that is locked to the glue ring 25 in the cartridge 24 are cut off.

The controller now reverses the motor 46 and causes the magazine 12 to
The distal end portion is pulled out from the magazine main body distal end receiving portion 66 by slightly hanging the door, and the state shown in solid line in FIG. 7 is obtained. At the same time, the motor 60 drives the spur gear 58, so that the abutment 54 is retracted in the direction in which the film intake section 52 is also moved away from it, resulting in the state shown by the solid line in FIG.

As a result, the magazine 12 loses its support and falls into the discharge path 90. At the time of this fall, the width direction protrusion 64 is already located at a position that does not correspond to the receiver pin 62, so the receiver 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, FIG. i9 and FIG. 10 show a film feeding device 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 meshes 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 abutment 9
6 is pivotally supported by a hinge lOO to the frame 72 of the film intake section 52, and a drive shirt (1) is located near the tip.
02 is pivotally supported. This drive shaft lO2 can rotate around the hinge 100 by receiving the driving force of a solenoid 104 attached to the machine base 11.

It has become a Noh performance. 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 the magazine 12 is moved toward the film intake section 52, the rotation of the motor 99 causes the spur gear 98 to drive the magazine 12 toward the film intake section 52 via the rack 94, and the front end of the magazine body is received. 66 to enable feeding operation of the negative film 30.

Also, when the negative film 30 is finished being fed, the motor 99
As shown in FIG. 10, when the magazine 12 is pulled out from the magazine main body tip receiving part 66 due to the reverse rotation of the
2 is caused to fall and be discharged on a support base 96 by reverse rotation of a motor 99.

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

In this embodiment, the widthwise protrusion 64 of the magazine 12 is formed over the entire length of the magazine 12, and a cutout 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 arranged 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 l.

2 moves in the direction of the film intake section 52, the pin 62 elastically deforms the plate spring 112 to enable the magazine 12 to move to the right in FIG. When the main body tip receiving portion 66 is pulled out and returned, the pin 62 of the receiver is inserted into the plate spring 112.
It enters above and corresponds to the notch 110.

Further, in this embodiment, the magazine 1 protruding from the support base 54
Even when the amount of protrusion of the magazine 2 is large, the distal end of the magazine 12 is surely supported and guided so that the distal end of the magazine 12 does not enter the discharge path 90 unintentionally.

Further, in this embodiment, the light shielding plate 1 is attached to the magazine tip receiving portion 66.
14 is pivotally supported. This light shielding plate 114 is
In the extracted state of 2, the entrance opening of the magazine tip receiving section 66 is blocked by its own weight to prevent light from entering the film intake section 52, but when the magazine 12 is inserted, it is pushed up by the magazine tip and the magazine tip receiving section 66 is opened. It is supposed to be done.

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. Furthermore, by maintaining the entire magazine loading stand 10 in a light-shielded state, it is possible to eliminate the light-shielding structure when the magazine 12 and the film intake section 52 are coupled.

[Effects of the Invention] As explained above, in the magazine for a film supply device according to the present invention, a film winding cartridge is housed in the magazine main body, the magazine is loaded into the film supply device, and the leading edge of the film is delivered to the developing machine. The cartridge protrudes from the magazine body while sandwiching a cartridge accommodating part provided in the magazine body to accommodate the cartridge, a film outlet formed in the magazine body, and a leader provided in the film outlet and attached to the leading edge of the film. Since the present invention includes a nipping and guiding means for reliably delivering the leader tip to the developing machine, it has an excellent effect of reliably guiding the leader to the developing machine and enabling automatic development.
