Description

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

[Background Art and Problems to be Solved] An automatic developing device that connects a thin leader to the tip of a film protruding from a cartridge, and automatically develops the film by pulling out the film by sequentially moving the leader into each developing tank. There is. According to this automatic developing 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, once all the films have been pulled out from the cartridge and development has been completed, the operator must reattach the leader to the next cartridge and set it in the developing machine. For this reason, although developing is done automatically, it is necessary to manually load the film into the developing machine.
This will cause a decrease in work efficiency.

For this reason, the applicant of the present invention has already proposed a film supplying device that enables automatic development by setting a large number of films in a developing machine (Japanese Patent Application No. 59-278990).
By using the magazine used in this device, it is possible to set multiple cartridges in the magazine and automatically send the film pulled out from the cartridges to the developing device. By preparing a large number of magazines in advance, it is possible to quickly The magazine can be exchanged and a large number of films can be developed automatically in sequence.

The magazine set in the developing machine in this way is
A leader attached to the leading end of the film protrudes from the magazine body, and the leader is held between feed rollers of a developing machine, thereby applying driving force to the leader.

Therefore, in order to ensure that the leader is held between the nipping rollers of the developing machine, it is necessary to accurately attach the leader to the magazine and to the developing machine.

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, it is an object of the present invention to provide a film feeding device that can reliably feed a film leader to a developing machine when a magazine is attached to the developing machine.

[Summary and operation of the invention] In the film supply device according to the present invention, a film winding cartridge is housed in a magazine main body, and a leader attached to the leading end of the film is made to protrude from the magazine main body, and a limiting means is used to prevent the film from entering the magazine. This is a film feeding device that limits the amount of insertion, attaches the magazine to the developing machine, and feeds the leader and film to the developing machine.With the magazine body attached to the developing machine, the tip of the leader reaches the conveyance roller of the developing machine. The biased arrangement is characterized in that the leading end of the leader is held between transport rollers and the film is sent to the developing machine.

Therefore, in the present invention, the mounting position of the leader with respect to the magazine is uniformly determined, so that when the magazine is properly installed in the developing machine, the leader is reliably held by the supply roller of the developing machine and pulled out. It turns out.

The magazine is arranged so that when the magazine is attached to the developing machine, the leader tip comes into contact with the conveyance roller and the leader is bent, so that the leader tip can be easily held between the conveyance rollers.

[Embodiment of the Invention] FIG. 1 shows a magazine 10 used in this embodiment,
FIG. 2 shows the magazine 10 in a state before it is attached to the developing machine 12.

As shown in FIG. 1, the magazine 10 is formed into a box shape with the top of the magazine body 14 open, and a cover 18 pivotally supported at one end by a hinge 16 (see FIG. 2) opens and closes the inside of the magazine body 14. It is possible. An arm 22 protruding from near the tip of the cover 18 is engaged with a click 24 provided on the magazine body 14 when the cover 18 is closed, thereby maintaining the closed state.

The interior of the magazine main body 14 is a cartridge and film housing section 26, and in this embodiment, a pair of cartridges 28 can be accommodated therein. Between these cartridges 28 is a housing section 2.
A rib 30 is formed on the bottom surface of the magazine body 14 along the longitudinal direction of the magazine body 14 to restrict movement of the pair of cartridges 28 in the axial direction and prevent them from interfering with each other.

Further, the cartridge 28 accommodated in one end of the accommodating portion 26 in the state shown in FIG.
It is movable toward a pair of film outlet ports 32, which are openings formed at the other end, until it comes into contact with the front end wall 14A.

A negative film 36, most of which is wound up and housed on a reel 34 in the cartridge 28, has a thin flexible leader 40 attached to its drawn-out end portion with an adhesive tape 38. This reader 4
0 has a width sufficient to connect two negative films 36 in parallel with an adhesive tape 38, and its longitudinal dimension is such that the cartridge 28 is at the end of the accommodating portion 26 as shown in FIG. The length is such that the distal end portion 40A can protrude from the film outlet 32 even in the state where the film is disposed.

Projections 41A and 41B protruding toward each other from the magazine body 14 and the cover 18 are formed between the pair of film ejection ports 32, and felts 42A and 42B are attached to these projections. 42A and 42B are designed to tightly hold the leader 40 when the cover 18 is closed.

Herein, the reader 40 is shown in detail in FIG.
Both ends of the rear end portion 40B in the width direction protrude beyond both ends of the negative film 36 in the width direction, and correspond to stoppers 44 as limiting means projecting into the housing portion 26 of the magazine body 14. That is, the stopper 44 is formed at the end of a wall portion that protrudes in a direction that reduces the width of the housing portion 26, and when the rear end portion 40B comes into contact with this stopper 44, the leader 40 is not inserted into the housing portion 26. Quantity is limited.

As shown in FIG. 2, the magazine 10 mounted on a movable table 46 adjacent to the developing device 12 is manually fitted into a magazine tip receiving portion 52 of the developing device 12. This magazine tip receiving part 5
The magazine 10 may be moved by the driving force of a fluid cylinder or the like, or by forming a rack gear on the side surface of the magazine body 14 and pushing the magazine 10 by the rotation of a pinion that meshes with the rack gear. You may also take the following measures.

When the magazine body 14 is fitted into the magazine tip receiving portion 52 in this manner, the tip portion of the leader 40 protruding from the magazine body 14 is sized to be held between the conveyance rollers 54 and 56 of the developing device 12. . These conveyance rollers 54 and 56 are rotationally driven before the magazine body 14 is fitted into the magazine tip receiving section 52, and the conveyance rollers 54 and 56 are driven to rotate before the magazine body 14 is fitted into the magazine tip receiving section 52, and the leader 40 being held therebetween is rotated.
is sent to a developing tank 58.

In particular, the magazine body 14 is
2, the leader 40 is preferably disposed so that its tip abuts against or between the conveying rollers 54 or 56, and the intermediate portion of the leader 40 is bent. As a result, the tip of the leader 40 is urged between the conveyance rollers 54 and 56, ensuring secure gripping.

The supply device 14 is provided with a drive device 60 for driving the moving table 46, so that the moving table 46 can be moved toward and away from the magazine tip receiving section 52, and the magazine body 14 can be dropped from the chute 62 after taking out the film. It's getting old.

Next, the operation of this embodiment will be explained.

The cartridge 28 is accommodated in the housing section 26 in the state shown in FIG. 1, and after the cover 18 is closed, the magazine body 14 is
is placed on the moving table 46.

Here, the magazine body 14 is manually fitted into the magazine tip receiving portion 52. Conveyance rollers 54 and 56 are rotationally driven simultaneously with this movement of the magazine body 14, and the leader 40 protruding from the magazine body 14 has its tip end 40A connected to the conveyance roller 54,
It is inserted between 56 and 56. Therefore, the leader 40 receives the driving force and is sent to the developing tank 58.

In this case, as shown in FIG. 4, the insertion amount of the rear end portion 40B of the leader 40 into the magazine body 14 is limited by the stopper 44, so that the magazine body 14 is fitted into the magazine tip receiving portion 52. Then, make sure that the tip 40A is the conveyor roller 5.
4,56. Therefore, the leader 40 reliably transfers the negative film 36 to the development processing tank 58 without causing a failure in drawing it into the conveyance rollers 54 and 56.
can be sent to.

Especially when the magazine body 14 is installed, the reader 40
If the arrangement is such that the leader 40 is bent, the leading end of the leader 40 will be reliably urged and held between the conveying rollers 54 and 56.

If the stopper 44 is not provided, the leader 40 will move inadvertently within the magazine 10, and the leading end 40A will be securely held between the conveying rollers 54 and 56 with the magazine 10 fitted into the magazine leading end receiving portion 52. This will cause it to become impossible to do so.

When all the negative films 36 are sent to the developing tank 58, the cartridge 28 is moved to the magazine front end wall 14.
By detecting the movement of the cartridge 28 when it is pulled in the A direction, the end of the negative film 36 is cut with a cutter (not shown), and the magazine body 1
4 is removed from the magazine tip receiving portion 52 and then slid on the chute 62 to be discharged.

Incidentally, if a large number of magazines 10 are stacked and placed on the moving table 46, dropped onto the moving table 46 one after another, and then supplied to the magazine tip receiving section 52 by driving force, a large number of magazines 10 can be automatically developed. Machine 1
It can be sent to 2.

Note that in order to urge the leader 40 toward the conveyance rollers 54 and 56 when the magazine 10 is attached, in addition to arranging the leader 40 to flex, an elastic body that presses the magazine 10 toward the conveyance rollers 54 and 56 is provided. Other biasing force applying means such as the above can also be applied.

Modified examples of the magazine will be explained below.
In either embodiment, the tip of the leader 40 is supplied to the developing device 12 in a biased state, as in the first embodiment.

Next, FIG. 5 shows a magazine body 14 according to a second embodiment of the present invention.

In this embodiment, the stopper 64 is not formed as a wall-like protrusion as in the previous embodiment, but protrudes from a portion of the magazine body 14 in the shape of a rib. The protruding position of the stopper 64 is at the longitudinally intermediate portion of the leader 40, and therefore the leader 40 is provided with a notch 66 to reduce its width. Therefore, the stopper 64 corresponds to the end surface 68 formed by the notch 66 and limits the amount of insertion of the leader 40 into the magazine body 14.

Further, in the third embodiment of the present invention shown in FIG. 6, a pair of pins 70 protrude from the bottom surface of the accommodating portion 26 and serve as a stopper. These pins 70 correspond to both ends in the width direction of the rear end portion 40B,
This limits the amount of insertion of the leader 40 into the magazine body 14.

In the fourth embodiment shown in FIG. 7, unlike the third embodiment, a single pin 72 protrudes from the bottom surface of the accommodating portion 26 and corresponds to the rear end 40B of the widthwise central portion of the leader 40. I'm starting to get a similar effect.

Next, a fifth embodiment of the present invention is shown in FIGS. 8 to 10. In this embodiment, a recess 80 shown in FIG. 10 is formed near both sides of the cover 18, and a stopper 82 is housed in the recess 80. The stopper 82 has its base pivoted to the cover 18 by a pin 84, and its tip extends from the recess 80 to the housing 26.
It is now possible to visit. Also stoppa 8
A leaf spring 86 disposed behind the housing 26 connects its tip end to a circular hole 88 formed in the leader 40 within the receiving portion 26.
It is protruding towards.

This protrusion is a vertical wall portion 82A with one side facing the feed direction of the leader 40 and along the thickness direction of the leader 40.
The opposite side is a slope 82B that is inclined from this.

Therefore, this stopper 82 allows movement of the leader 40 only in the direction to remove it from the magazine body 14. That is, the reader 40 is the magazine body 14
When pulling out from the hole (moving to the right in Figure 5), use the circular hole 8.
8 rotates the slope 82B and the stopper 82 is attached to the leaf spring 8.
6 into the recess 80,
It can be easily moved, and when inserted into the magazine body 14, the circular hole 88 comes into contact with the standing wall 82A, and the stopper 82 cannot be pushed into the recess 80, so movement is prevented.

Therefore, also in this fifth embodiment, the reader 40
can be pulled out from the magazine body 14,
Pushing into the magazine body 14 is restricted, making it possible to obtain the same effect as in the previous embodiment.

Note that in order to make the tip of the stopper 82 protrude into the accommodation portion 26, it is not necessary to use the leaf spring 86 as in this embodiment, but instead, another elastic body or the stopper 82 may be used.
The distal end portion may be inserted into the housing portion 26 by its own weight.

FIG. 11 shows a sixth embodiment of the invention. This embodiment differs from the previous embodiment in that the stopper 82 of the previous embodiment is arranged at the center of the cover 18 in the width direction, and the corresponding circular hole 88 is also provided at the center of the leader 40 in the width direction. .

Furthermore, in a seventh embodiment of the present invention shown in FIG.
A plurality of openings 92 are formed along the longitudinal direction of the leader 40 at the center in the width direction, and the stopper 82 corresponds to one of these openings 92.

These openings 92 connect the reader 40 to the developing section 58.
(See FIG. 2).

Next, FIGS. 13 and 14 show an eighth embodiment of the present invention. In this embodiment, the magazine body 14
A sprocket wheel 94 is pivotally supported by a pin 96, and a protrusion 98 of the sprocket wheel 94 is inserted into the opening 92. Therefore, it is preferable that the intervals between the plurality of protrusions 98 be equal to the intervals between the openings 92.

A ratchet foil 100 is fixed coaxially to the sprocket foil 94, and the tip of a leaf spring 102 is in contact with this ratchet foil 100.
The ratchet foil 100 is attached to the magazine body 14 with rivets 104.

Therefore, in this embodiment, the sprocket foil 9
4 is rotatable only in the clockwise direction in Figure 14, and the leader 4
When the leader 40 is about to be inserted into the magazine body 14, the sprocket wheel 94 is prevented from rotating counterclockwise, thereby limiting the insertion amount of the leader 40. are doing.

Next, FIG. 15 shows a ninth embodiment of the present invention. In this embodiment, rectangular notches 113 are formed on both sides of the leader 40 in a direction that reduces the width of the leader 40, and correspond to stoppers 115 attached to the magazine body 14. That is, the stoppers 115 are housed in recesses 117 formed in the openings of the side walls of the magazine body 14, and are pivotally supported to the magazine body 14 by pins 119. The stopper 115 is biased by the biasing force of the compression coil spring 121 interposed between the bottom of the recess 117 and the bottom of the recess 117.
The tip of the cutout 113 is adapted to fit into the notch 113.

Therefore, when the tip of the stopper 115 enters the notch 113, the stopper 115 is configured to limit the amount of insertion of the leader 40 into the magazine body 14. However, in this state, the longitudinal direction of the stopper 115 is inclined with respect to the longitudinal direction of the leader 40, so when the leader 40 moves in the direction of pulling out from the magazine body 14, the notch 113 moves the stopper 115 toward the compression coil spring 121.
The reader 40 is pushed into the recess 117 against the urging force of the magazine body 14, thereby making it possible to extract the leader 40 from the magazine body 14.

Therefore, the compression coil spring 12 of the stopper 115
The surface opposite to 1 connects the reader 40 to the magazine body 1.
The stopper 11 constitutes a slope for pulling out from the stopper 11.
5 serves as an engagement surface that maintains the stopper 115 inserted into the notch 113 and limits the insertion amount of the leader 40.

FIG. 16 shows a magazine body 14 according to a tenth embodiment of the present invention.

In this embodiment as well, the leader 40 is formed with a rectangular notch 123 similar to that of the previous embodiment, but in this embodiment, the stopper 11 of the previous embodiment is
5, a stopper 125 formed of a leaf spring is used.

This stopper 125 has one end connected to the magazine body 14.
The intermediate part is an inclined part 125A forming a slope approaching the longitudinal axis of the leader 40 while being inclined with the longitudinal direction of the leader 40, and the tip part is bent in the width direction of the leader 40 to form an engagement surface. The engaging portion 125B constitutes the engaging portion 125B.

Therefore, the stopper 125 of this embodiment is configured to also have the compression coil spring 121 of the previous embodiment, and when the leader 40 is inserted into the magazine body 14, the notch 123 engages with the engaging portion 125B.
It engages with the notch 1 to limit the amount of insertion, and when withdrawing, the notch 1
23 pushes the engaging portion 125B into the recess 117, thereby making it possible to remove the leader 40.

Next, FIG. 17 shows an eleventh embodiment of the present invention.

In this embodiment, the notch 1 formed in the leader 40
28 has a slope 128A in the direction of the negative film 36, and a block 130 that is inserted into the recess 117 and receives the biasing force of the compression coil spring 121 has a slope 130A at its tip, which corresponds to the slope 128A of the notch 128. , and its side surface is an engagement surface 13
0B and corresponds to the engagement surface 128B formed in the width direction of the notch 128.

Therefore, also in this embodiment, when the leader 40 is pulled out from the magazine body 14, the slope 1
28A pushes up the slope 130A of the block 130 to retract the block 130 into the recess 117, thereby allowing the leader 40 to be extracted, while being engaged when the leader 40 is pushed into the magazine body 14. Surface 128B engages engagement surface 130B to limit the amount of insertion.

Next, FIG. 18 and FIG. 20 show a twelfth embodiment of the present invention.

In this embodiment, a plurality of openings 92 are formed in the reader 40 along the longitudinal direction, similar to the seventh and eighth embodiments shown in FIGS. 12 and 13. These openings 92 correspond to stoppers 140 projecting from the ribs 30 of the magazine body 14. This stopper 140 has the function of restricting the insertion of the leader 40 into the magazine body 14 and making it possible to remove the leader 40, as in each of the embodiments described above, but unlike each of the embodiments described above, the stopper 140 is integrally attached to the magazine body 14. is formed.

That is, as shown in FIGS. 19 and 20, this stopper 140 has a slope 140 on the cartridge 28 side.
A, the outlet side of the magazine body 14 is the engagement surface 140B
It is designed to be inserted into the opening 92 in the attached state.

On the other hand, a leaf spring 142 is attached to the cover 18 in correspondence with the stopper 140, and the tip of the leaf spring 142 projects toward the outlet side of the magazine main body 14 and comes into contact with the stopper 140. A biasing force is generated.

Therefore, in this embodiment, as shown in FIG. 19, the opening 92 of the leader 40 enters into the stopper 140, and when the leader 40 is extracted, the portion between the openings 92 enters the stopper 140, as shown in FIG.
It is now possible to move beyond this.

Further, as shown in FIG. 18, an elastic body 144 such as a sponge is fixed to the cover 18, and is adapted to bias the cover 18 in the direction of releasing it when the cover 18 is in the closed state.

In this embodiment, the cover 18 is configured such that a recess 146 formed at the distal end thereof engages with the distal end of a latch member 148 attached to the magazine body 14 to maintain the magazine body 14 in a closed state. This latch member 148 is also attached to the cover 1.
8 has an elastic body (not shown) in a direction that is biased toward the recess 146 in the closed state. A fixed lid 150 is provided at the attachment portion of the latch member 148 and forms a film outlet 32 between it and the magazine body 14.

Therefore, in this embodiment as well, the reader 40 and the cartridge 28 are attached as shown in FIG.
By arranging the leading end of the leader 40 to be in contact with the conveying rollers 54 and 56 and to be slightly bent, the leader 40 can be reliably sent to the developing machine 12.

Next, FIGS. 21 to 23 show a thirteenth embodiment of the present invention. This embodiment has a magazine body 14 having the same structure as the previous embodiment, and a stopper 140 is similarly formed on the rib 30. However, the elastic body 1 used in the above embodiment
44 is not used.

Also, an elastic body 152 similar to the elastic body 144 of the previous embodiment is attached to the rib 30 and corresponds to the tail end of the leader 40 in the attached state. This elastic body 15
2 has the role of preventing the reader 40 from inadvertently moving toward the cartridge 28, and also has the role of urging the cover 18 in the opening direction.

Therefore, in this embodiment, as shown in FIG. 22, the magazine 1 has a narrow distance between the rib 30 and the cover 18.
It is best used at 0.

Further, in this embodiment, the film outlet 32, more specifically, the protrusion 42B protruding from the film outlet 32 presses the leader 40 downward and presses the stopper 1.
40 so that the opening 92 can be easily engaged with the opening 92. However, a protrusion for pressing the leader 40 may be provided on the cover 18 or the like at a portion other than the film outlet 32, for example near the stopper 140.

Furthermore, in this embodiment, the cartridge 2 is attached to the cover 18.
Leaf springs 154 are attached corresponding to the cartridges 8 and 8 to press the cartridge 28 against the bottom surface of the magazine body 14.

In this embodiment, when the cover 18 is closed, the reader 4
0 is in a state where the opening 92 is inserted into the stopper 140 as shown in FIG. 22, so the amount of insertion of the leader 40 into the magazine body 14 is limited, and the same effect as in each of the above embodiments is obtained. It is now possible to do so.

[Effects of the Invention] As explained above, in the film feeding device according to the present invention, the film winding cartridge is accommodated in the magazine body, and the leader attached to the tip of the film is made to protrude from the magazine body, and the limiting means is used to prevent the film from entering the magazine. This is a film feeding device that limits the amount of insertion into the developing machine, attaches the magazine to the developing machine, and feeds the leader and film to the developing machine. As an arrangement that is biased toward the roller,
Since the film is fed to the developing device by holding the tip of the leader between the conveying rollers, it has an excellent effect of being able to reliably feed the leader to the developing device.
