The interrupted film can be developed.

Example of Invention

FIG. 3 shows a state in which the leader 10 used in this embodiment is attached to the leading end of the film 14 protruding from the cartridge 12. The base end of the film 14 is locked to the winding core 12A in the cartridge 12. The leader 10 is made of a thin sheet material such as synthetic resin and has a plurality of openings 16 formed along the longitudinal direction thereof.

The film 14 and the leader 10 are bonded to each other with the adhesive tape 2
0 is used. An identification line 22 as an identification mark is applied in a narrow width to the other end of the reader 10 over the entire width direction.

FIG. 4 shows a magazine 24 in which the reader 10 and the film 14 are stored. This magazine 24 is box-shaped, and has a hinge 24A at the upper end of the magazine body 25.
When the lid 26 that can be opened and closed via the is closed, the inside is shielded except the film supply port 24B.

Inside the magazine body 25, a pair of standing walls 2 is provided at the center in the width direction.
8 and 30 are formed along the longitudinal direction. The top surfaces of these standing walls 28 and 30 are reader mounting surfaces, and the space between the magazine main body side walls 25A and 25B is the accommodation space for the cartridge 12, respectively.

The standing walls 28 and 30 are the film supply ports 2 of the magazine body 25.
A recess 32, the height of which is temporarily reduced, is formed in the vicinity of 4B to form a support surface of the reader 10. That is, since the leader 10 is made of a flexible thin material such as synthetic resin and maintains a flat state in the free state, the recess 32 is formed even when it is placed on the standing walls 28 and 30. Nevertheless, it remains flat. However, when a compressive force is applied in the longitudinal direction thereof, it elastically bends to be bent along the concave portion 32, and the vicinity of the tip can be in a state of being directed obliquely upward as compared with the free state.

As shown in FIG. 6, a gear (spout wheel) 34 is axially supported between the standing walls 28 and 30, and a part of the inner circumference of the endless conveyor belt 36 serving as the leader feeding means is engaged with the engagement protrusion 36A. There is. Also, this endless conveyor belt 3
The other part of the inner circumference of 6 has standing walls 28 and 30 and a magazine rear wall 25.
It is wound around and engaged with a gear 38 which is arranged between C and C. The gear 38 is fixed to a rotary shaft 40, and both ends of the rotary shaft 40 are pivotally supported by the magazine main body 25 via brackets 42 and 44.

For this reason, the endless conveyor belt 36 is in a parallel state between the gears 34 and 38, and the engaging protrusions 36B protruding at regular intervals on the outer periphery protrude from the top surfaces of the side walls 25A and 25B, and the standing wall 2
It is adapted to engage with the opening 16 of the reader 10 placed on the 8 and 30.

The plurality of engaging protrusions 36 </ b> B projecting to the outer periphery of the endless transport belt 36 are inserted into the openings 16 formed in the reader 10 to drive the reader 10.

An L-shaped engaging projection 46 projects upward from the standing walls 28 and 30 so that the film mounting end of the leader 10 can be inserted. At the intervals of these engaging protrusions 46,
The reader 10 is attached and positioned.

Therefore, the end portions of the plurality of leaders 10 are connected to the engaging protrusions 4 respectively.
6 and the opening 16 is engaged with the engagement protrusion 36B, the reader 10 is placed on the standing walls 28 and 30 at regular intervals and the identification line 22 at the tip is exposed at regular intervals. Can accurately detect the state in which the reader 10 is attached.

The lid 26 has a pair of ribs 26A, 26 at the center in the width direction.
B are formed parallel to each other along the longitudinal direction. These ribs 26A and 26B cover the lid 26 with the magazine body 25.
In the closed state, they are arranged so as to face the upper end portions of the upright walls 28 and 30, respectively, and the vicinity of the tip end portion of the engagement protrusion 36B is accommodated. Therefore, it is taken into consideration that the reader 10 is not accidentally disengaged from the engagement protrusion 36B when the lid 26 is closed to the magazine body 25.

The ribs 26A and 26B may be provided with projections that enter the recesses 32 of the standing walls 28 and 30, and the reader 10 may be bent with the lid 26 closed.

The gear 34 arranged in the standing walls 28, 30 is pivotally supported by a pin 54 via a sleeve 52 as shown in FIG. 7, and the pin 54 is pivotally supported by the standing walls 28, 30.
A pinion 58 is pivotally supported on the outer periphery of the sleeve 52 via a one-way clutch 56. The one-way clutch 56 transmits only the clockwise rotation of the pinion 58 shown in FIGS. 6 and 7 as the clockwise rotation of the sleeve 52 and the gear 34. The pinion 58 has standing walls 28 and 30.
A rack 62 guided so as to be linearly movable between the two meshes. One end of the rack 62 is connected to a rod 64, and the rod 64 is guided linearly by penetrating a guide block 66 attached to the magazine body 25. The front end of the rod 64 is exposed from the film supply port 24B of the magazine body 25, and when it is pushed into the magazine body 25, the rack 62 rotates the pinion 58 clockwise in FIGS. The endless conveyor belt 36 is moved by the required feeding length of the reader 10 via the intermediary end. As a result, the tip of the reader 10 is sent to the developing device 68.

Since the rod 64 is urged by the urging force of the compression coil spring 70 in the direction of projecting to the film supply port 24B of the magazine body 25, the rack 62 is restored when the pressing force on the rod 64 is released, but the one-way clutch is released. Since the gear 56 is arranged, the gear 34 does not rotate in the counterclockwise direction in FIGS.

On the other hand, the gear 38, which wraps and supports another part of the endless conveyor belt 36, has its rotation shaft 40 rotated at a constant angle by a moderating means. That is, the block 72 is fixed to the rotary shaft 40 between the gear 38 and the bracket 44. Recesses 72A are formed at three locations on the outer peripheral portion of the block 72 so that rollers 74 can be inserted therein. The roller 74 is attached to the tip of an arm 78 that is pivotally supported by the magazine body 25 via a bracket 76, and a tension coil spring 80 is interposed between the arm 78 and the standing wall 30. Therefore, when the endless conveyor belt 36 is rotated by the required feeding length of the reader 10, the roller 74 enters the recess 72A and stops the endless conveyor belt 36.

In order to ensure this stopped state, a stopper pin 82 corresponds to the gear 34 as shown in FIG. That is, the stopper pin 82 projects from the rack 62 and is inserted between the tooth tips of the gear 34. However, with this stopper pin 82, the rack 62 moves to the left in FIG.
8 and the one-way clutch 56, when the gear 34 receives a rotational force, it moves together with the rack 62 and projects out of the rotation track of the gear 34 to enable the gear 34 to rotate.

Therefore, the gear 34 is rotated by the required angle and the rack 62 is rotated.
Is restored, the gear is again inserted into the rotation locus of the gear 34, that is, between the tooth tips to stop the rotation of the gear 34. As a result, when a plurality of leaders 10 are in close contact with each other and the leader 10 at the leading end receives a tensile force and is sent to the developing device,
Even when a force for inadvertently rotating the endless conveyor belt 36 is generated by receiving the tensile force due to the frictional force of the next leader 10 or the like, the endless conveyor belt 36 is surely prevented from rotating and moves. There is no such thing.

The magazine body 25 and the lid 26 have small-diameter portions 25E and 26B in the vicinity of their leading ends through stepped portions 25D and 26A, and serve as insertion portions into the developing device 68. A pair of projections 25F and 25G each having a planar semi-circular shape project from the inner walls of the side walls 25A and 25B in the magazine body 25, and the space between the standing walls 28 and 30 and the projections 28 and 30 serves as a guide space for the cartridge 12. ing.

Between the pair of protrusions 25F is a mounting portion of a magnet 84 for maintaining the lid 26 in the magazine main body 25 in a closed state. The attracting member 8 is attached to the lid 26 corresponding to the magnet 84.
6 is attached.

The magazine body 25 has side walls 25A, 25 near the tip thereof.
Guide ridges 88 and 90 are formed on the upper end of the inner periphery of B, and the protruding ribs 26 of the lid 26 are inserted into these guide ridges 88 and 90.
C is accommodated so that the inside of the magazine body 25 is shielded from light.

As shown in FIG. 1, the developing device 68 is provided with a supply cover 106 on the main body 102 via a pin 104. The supply unit cover 106 covers the supply unit 110 for sending the film 14 sent out from the magazine 24 to the developing unit 108 of the developing device 68.

The supply unit lid 106 has a cylindrical portion 112 as a magazine connecting portion.
Protrudes obliquely upward, and accommodates the small diameter portions 25E and 26B of the magazine body 25. Therefore, the lid 26 does not open when the small diameter portions 25E and 26B are inserted into the tubular portion 112.

A lock unit 114 is provided in the supply unit 110 to prevent the magazine 24 from being pulled out and the supply unit lid 106 from being opened carelessly when the developing operation is started with the magazine 24 inserted. ing.

That is, the middle portion of the arm 118 is pivotally supported by the pin 112 on the tubular portion 112. This arm 118 has a tip hook 1
18A constitutes a magazine extraction preventing means corresponding to the opening 25H formed near the tip of the magazine main body 25, but is biased by its own weight in a direction away from the opening 25H.

However, the end of the arm 118 opposite to the hook 118A corresponds to the arm 120, and the hook 118A is engaged with the opening 25H by the driving force of the arm 120. This arm 120 is fixed to one end of an arm 122, and the middle part of the arm 122 is pin 1
It is pivotally supported at 24 on the main body 102. A hook portion 122A is formed near the end of the arm 122 to which the arm 120 is attached, and a lid opening preventing means is provided corresponding to the hook 106A protruding inside the supply portion lid 106 by the biasing force of the compression coil spring 125. I am configuring.

The end of the arm 122 opposite to the hook 122A is pivotally supported by the plunger 128 of the solenoid 126. The solenoid 126 is adapted to receive a driving force by the control circuit 130 of the developing device 68. This control circuit 13
When the development is started, 0 energizes the solenoid 126 to rotate the arm 122 against the biasing force of the compression coil spring 125, engage the hook portion 122A with the hook 106A, and via the arm 120, the arm 118. Rotate
The hook portion 118A is adapted to engage with the opening 25H. Therefore, during the developing operation, the supply unit lid 106 is not opened carelessly, and the magazine 24 is not carelessly pulled out from the cylindrical portion 112.

Adjacent to these locking means 114 is provided drive means 142 for actuating the rod 64 of the magazine 24. As shown in FIG. 9, the drive means 142 is provided with a drive rod 144 which is guided by a cylinder 143 and is slidable in the axial direction, with its tip end corresponding to the tip end of the rod 64. A roller 146 corresponds to the other end of the.

The roller 146 is pivotally supported on the tip of the crank arm 148, and the base end of the crank arm 148 is fixed and the base end of the crank arm 152 is fixed on the rotary shaft 150 pivotally supported on the main body 102. Has been done. A roller 154 is pivotally supported at the tip of the crank arm 152 and is in contact with the outer circumference of the eccentric cam 156. The fixed shaft 158 of the eccentric cam 156 is attached to the output shaft of the motor 160.

The motor 160 is controlled by the control circuit 130, and at the time of rotation, the eccentric cam 156 rotates the crank arm 152 around the axis of the rotary shaft 150, which causes the drive rod 144 via the crank arm 148 and the roller 146.
Drive rod 144 is pushed up by drive rod 144.
4 is pushed into the magazine 24, the leader 10 is pushed out of the magazine 24, and the leading end portion is driven by the endless belt 162.
Is designed to engage with.

The drive endless belt 162 is wound around the pair of gears 164 and 166 in the supply unit 110, and the projection 162A protruding from the inner peripheral portion is meshed with the gears 164 and 166, like the endless conveyor belt 36 in the magazine 24. . Further, the protrusion 162B formed on the outer periphery of the drive endless belt 162
Is the opening 16 of the reader 10 sent out from the magazine 24.
And the leader 10 is sent out to the developing unit 108. Therefore, the drive endless belt 162 is arranged at a position corresponding to the tip of the leader 10 sent from the magazine 24.

Feed rubber rollers 170 and 172 are attached to the central shaft 168 of the gear 166 as shown in FIG. 2, and are for feeding the film 14 connected to the leader 10. The feeding rubber rollers 170 and 172 are provided with a feeder cover 1.
The pressing roller 174 attached to the contact member 06 is brought into contact with the pressing roller 174, so that the film 14 is reliably sent to the developing unit 108. These feed rubber rollers 170,
A film sensor 176 is provided between the developing unit 108 and the developing unit 108.
Is attached, and the rear end of the film is detected and its signal is sent to the control circuit 130.

A guide plate 178 is arranged above the gear 164 so that the leader 10 is surely engaged with the protrusion 162B of the drive endless belt 162 and that the film 14 is surely sent to the rubber rollers 170 and 172. .

Further, as shown in FIGS. 2 and 8, a cartridge support plate 180 is arranged on each side of the gear 164. When the leader 10 is sent to the developing section 108 by the drive endless belt 162, these patrone support plates 180 support the patrone 12 connected to the leader 10 via the film 14 and support only the film 14 from the patrone 12. It can be pulled out to the developing unit 108.

Further, these cartridge support plates 180 can be moved in the contacting / separating direction with respect to the developing section 108 by a guide means (not shown), and are normally pressed by the elastic body urging force in the direction away from the developing section 108. However, when all the film 14 in the cartridge 12 is pulled out, the tension acting on the film 14 is received through the core 12A, and the developing unit 108 can be accessed. This approaching state is detected by a limit switch (not shown), and the signal is detected by the control circuit 13.
It is supposed to be sent to 0.

When this film end state is detected, the control circuit 13
A cutter 186 driven by 0 is arranged between the cartridge support plate 180 and the developing section 108. In this cutter 186, the upper blade 188 and the lower blade 190 have a film 14
Are arranged above and below the movement locus of the above, and the lower blade 190 is lifted by a driving means such as a solenoid (not shown) and the film 14 is sandwiched between the lower blade 190 and the upper blade 188 for cutting.

Next, the operation of this embodiment will be described.

Prepare a plurality of readers 10 that are connected to the film 14 by the adhesive tape 20 in advance, and place them in the magazine 2 at regular intervals.
Install in 4. In this case, the leader 10 may be brought into contact with the engaging projections 46 at the film connection end portions in order from the frontmost portion thereof, whereby the identification lines 22 are arranged at regular intervals, so that the two leaders 10 are arranged in a stack. If they are attached at different intervals, this can be quickly detected and corrected. If the distance between the engagement protrusion 46 and the top surfaces of the standing walls 28 and 30 is set to a size such that only one reader 10 can be inserted, it is possible to reliably prevent the two readers 10 from being stacked.

With the lid 26 closed to the magazine body 25, the small diameter portions 25E and 26B of the magazine 24 are inserted into the cylindrical portion 112.

If a development start button (not shown) is operated, the development work starts. When the developing work is started, the control circuit 130
Activates the solenoid 126, the hook portion 122A,
118A is a hook 106A of the supply unit lid 106,
The supply portion lid 10 is engaged with the opening 25H of the magazine body 25.
The opening of 6 and the withdrawal of the magazine 24 are prevented. Therefore, the magazine 24 will not be carelessly taken out during the developing operation, and the supply section lid 106 will not be opened to expose the film being developed to light.

On the other hand, the control circuit 130 drives the motor 160 and the eccentric cam 156 rotates. Therefore, the crank arm 152,
148 rotates and drive rod 144 pushes rod 64 into magazine 24. This rotational force is transmitted to the rack 62, and the pin 54 fixed to the rack 62 projects from between the tooth tips of the pinion 58 to rotate the pinion 58.
The rotation of the pinion 58 causes the endless conveyor belt 36 to rotate, and the leader 10 is pushed out from the tip of the magazine 24 by the engagement protrusion 36B.

As a result, the leading end of the leader 10 is brought into contact with the driving endless belt 162 in the supply unit 110. In this case, since the drive endless belt 162 is rotated at the same speed as the film transport speed in the developing unit 108, its rotation speed is relatively low, and the feed speed of the reader 10 is relatively high. Therefore, the leader 10 is bent by receiving the compressive force. The bent leader 10 is formed in the recess 3 of the standing walls 28 and 30.
2, so that the leader 10 drives the endless belt 16
Endless conveyor belt 16 in a state in which it is susceptible to the rotational force of 2
2 is bent along the traveling direction of the drive endless belt 162, and the protrusion 162B is rotated by the rotation of the drive endless belt 162.
Securely engages the opening 16 of the developing unit 108,
Will be drawn to.

Further, since the bent leader 10 is separated from the following leader 10 in the thickness direction, even when the engaging opening 16 is deformed and enters the opening of the next leader, this is released, and the next leader is carelessly taken. Does not receive tensile force.

When the leader 10 is engaged with the drive endless belt 162, the leader 10 has a dimensional relationship in which the engagement with the engagement protrusion 36B is released.

When the leader 10 is pulled out to the developing unit 108, the film 14 and the cartridge 12 connected to the leader 10 are also pulled out from the magazine 24 and reach the supply unit 110. However, the cartridge 12 that has reached the inside of the supply unit 110 contacts the cartridge support plate 180, and the movement to the developing unit 108 is stopped. Therefore, the film 14 pulled by the reader 10 is taken out from the cartridge 12 and is transferred to the developing unit 10.
8 and the developing work is carried out.

When the entire amount of the film 14 is pulled out from the cartridge 12, the film 14 connected to the end of the winding core 12A transfers the cartridge 12 to the developing unit 108 via the winding core 12A.
Since it is pulled to, the cartridge support plate 180 is
Move in 8 directions. As a result, the cutter 186 operates and the end of the film 14 is cut off. At the same time, the cartridge 12 from which the tensile force has been released falls inside the supply unit 110 and is discharged.

The end of the cut film 14 is the film sensor 176.
Control circuit 130 again drives motor 160 to raise drive rod 144 and push rod 64 up. Therefore, the next reader 10 is projected into the supply unit 110, and the developing work is performed as in the previous time.

Next, a plurality of cartridges 1 stored in the magazine 24
A case will be described in which it is necessary to interrupt the separate urgent development processing film and develop it first while continuous development of No. 2 is performed. In this case, the operator operates the operation button for interrupt development work. In this case, in the state where the end of the film being developed during the operation is detected by the film sensor 176, unlike the continuous development, the motor 160 is deactivated. Further, in this state, the power supply to the plunger 128 is released, and the magazine 24 can be extracted and the supply unit lid 106 can be opened.

Therefore, the operator opens the supply unit cover 106 in the clockwise direction in FIG. 1 around the pin 104 and manually drives the leader 10 with the film set in the state shown in FIG.
2 and the cartridge 12 is engaged with the cartridge support plate 1
The supply unit lid 106 is closed again while being in contact with 80.
As a result, the plunger 128 is excited again, the opening of the supply unit lid 106 and the withdrawal of the magazine 24 are blocked, and the developing operation is started. After that, when the development of the manually supplied film 14 is completed, the film in the magazine 24, which has been interrupted until then, is sent to the supply unit 110 again.

Further, when the work is interrupted in this way to develop separate films, if there are a large number of the films, these urgently processed films are accommodated in separate magazines, and this magazine is already connected to the tube portion 112. By replacing the magazine 24 and supplying the same, the interrupt developing work similar to the case where the supply cover 106 is opened is carried out, and when the developing work is completed, the interrupted films are accommodated again. The magazine 24 that has the cylinder 112
You can set it.

In this way, when the developing work of the film in the magazine 24 is interrupted, after the developing film which has been pulled out to the developing device 68 with the operation button for the interrupting development work being pushed to the end, Since the next reader in the magazine is not sent to the supply unit 110 and the interrupt development work is performed, the unprocessed film in the magazine 24 in which the development is interrupted is not inadvertently exposed.

When all the films in the magazine 24 have been developed, the solenoid 126 is de-energized and the locking means 114 is released. Therefore, the worker pulls out the magazine 24 and again loads the magazine 24 into which the new film is loaded. 11
Attach it to 2. The supply unit cover 106 may be provided with a latch mechanism that can be manually released to prevent accidental opening.

〔The invention's effect〕

Since the present invention is configured as described above, even when a large number of films contained in the magazine are sequentially developed, it is possible to develop separate films by interruption between them. Have an effect.
