Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a photographic printing paper magazine for supplying photographic printing paper to a photographic printing apparatus.

[Prior art]

When supplying photographic printing paper to a photographic printing apparatus, there is one in which the photographic printing paper stored in a roll is pulled out from the outer periphery and supplied.

In this case, the photographic printing paper is stored in a magazine, and this magazine is loaded into the photographic printing apparatus. The printing paper is sequentially drawn from the outer circumference of the roll-shaped portion and supplied to the photo printing apparatus.

However, since it is necessary to properly use photographic papers having different widths in the photo printing apparatus, it is necessary to store photographic papers having different widths in a plurality of magazines and use these as necessary. In order to change the width of the photographic paper used here, the used magazine must be removed from the printing device.If the leading edge of the photographic paper is exposed from the magazine, this exposed part becomes the cover part when removing the magazine. Therefore, reuse becomes impossible.

For this reason, a photographic paper transport roller is provided between the roll-shaped portion of the photographic paper and the photographic paper outlet of the magazine, and this roller is manually driven before the magazine is detached from the printing apparatus, and the leading end of the photographic paper is inserted into the magazine. It is convenient to have a configuration that pulls in.

For this reason, when the magazine is loaded into the printing apparatus again, the photographic paper is pulled into the magazine, so a mechanism for pulling it out is required. As this mechanism,
There is one in which the outer periphery of a roll of photographic printing paper is always pressed by a drive roller, and the axial end of this drive roller is projected outside the magazine. As a result, when the drive roller is axially rotated, a rotational force is applied to the roll-shaped photographic printing paper, and the leading end of the photographic printing paper can be sent to the printing apparatus.

However, since the printing paper is conveyed during the printing process by being pulled by the drive system on the side of the printing apparatus, the pressing force of the drive roller acts as a load and adversely affects the printing paper conveyance system.

Therefore, a structure is conceivable in which the drive roller is separated from the outer periphery of the roll-shaped printing paper by an urging force, and the drive roller is brought into contact with the outer periphery of the photographic paper against the urging force when necessary. There is. In this case, the operating knob for applying the rotational force to the drive roller and the operating knob for bringing the drive roller into contact with the outer periphery of the printing paper are the same. That is,
A rotating roller is hung in parallel with the drive roller on both side surfaces of the rolled photographic paper on which the rotating shaft is rotatably supported, one end of which is projected out of the magazine, and an operation knob is attached. Gears are attached to the drive roller and the rotary roller, respectively, but these gears are usually offset from each other in the axial direction, and the gears mesh with each other when the operation knob is moved in the axial direction. The gears are opposed to each other in the shape of a bevel gear, and when meshed, the drive roller is moved against the biasing force, and the gears are structured to mesh with each other in the maximum radius portion. In this state, by rotating the operation knob, a rotational force is applied to the drive roller via the gear, and the photographic paper can be sent out by the rotation of the drive roller.

[Problems to be solved by the device]

However, the movement of the operation knob for engaging the gears corresponds to the width direction of the printing paper, and since this operation is performed after the magazine is loaded in the printing apparatus, the magazine may shift in the width direction of the printing paper. . This misalignment causes a meandering in the conveyance during the printing process, which makes it impossible to accurately position the printing paper.

In consideration of the above facts, the present invention is a photographic printing paper which can properly send the printing paper to the main body of the printing apparatus when the printing paper is pulled out after the magazine is loaded, and does not cause meandering in the conveyance of the printing paper during the printing process. The purpose is to get a magazine.

[Means for Solving the Problems]

In the photographic printing paper magazine according to the present invention, a long photographic printing paper is wound into a roll and accommodated in the main body of the printing apparatus, and a photographic printing paper pulled out from the photographic printing paper roll is arranged in the middle of the conveyance path. A pair of rollers provided for nipping and transporting the printing paper, a biasing means for biasing the pair of rollers in directions away from each other, and a direction of loading the magazine main body to the printing apparatus main body in the same direction. An operating portion that is operated in a direction, and a moving means that moves at least one roller in a direction in which the photographic paper is pinched against the urging force of the urging means when the operating portion is operated. .

[Action]

Before loading the magazine body into the printing apparatus body, the photographic paper is kept shielded from light. Here, when the magazine body is loaded into the printing apparatus body, the magazine body and the printing apparatus body communicate with each other.

When the operating portion is operated in this state, the guide roller is moved by the moving means against the urging force of the urging means, and the photographic printing paper pulled out from the outer periphery of the roll-shaped photographic printing paper is nipped by the pair of rollers. The photographic paper can be guided to the main body of the printing apparatus by rotating. The operation of the operation unit is the same as the loading direction of the magazine main body into the printing apparatus main body. In other words, if the operation direction is not the same as the loading direction, the loading accuracy between the magazine body and the printing apparatus body may be affected by the force operated by the operator,
Problems such as lifting of the magazine or flexing of the magazine occur, and defective conveyance (meandering or jamming) easily occurs. In this respect, in the present invention, since the operation direction of the operation portion is the same as the loading direction, the loaded state can be ensured and the force is not applied in the width direction of the printing paper so that the meandering or the like does not occur.

Further, when the printing paper reaches the main body of the printing apparatus, it is usually pulled out by the transport system on the main body side of the printing apparatus. In this case, the rollers are separated from each other by the urging force of the urging means. You can pull out the paper freely.

On the other hand, even when rewinding the photographic paper into the magazine body, the pair of rollers are separated from each other (non-operation of the operation part), so the rewinding load is reduced and scratches on the photographic paper surface are prevented. You can

〔Example〕

As shown in FIGS. 1 to 3, in the magazine according to the present embodiment, a synthetic resin lower case 10 and an upper case 12 constituting the magazine body are rotatable with respect to each other via a hinge 14. Therefore, the insides of the lower case 10 and the upper case 12 can be brought into a light-shielding state by making their openings coincide with each other around the hinge 14.

Semi-circular notches 16 and 18 are formed on the opening end faces that are in close contact with each other when the lower case 10 and the upper case 12 are closed, so that the lower case 10 and the upper case 12 form a circular shape when closed. It has become.

The rotary dials 20 and 22 are housed in the notches 16 and 18, respectively. These rotary dials 20 and 22 have a configuration in which cylindrical portions 20B and 22B are continuous with the outer circumferences of the discoid portions 20A and 22A.
The shaft cylinders 20C and 22C project from the 0A and 22A to the opposite sides of the cylinder parts 20B and 22B.
By rotating the outer circumference of C with the inner circumference of the notches 16 and 18, the rotary dials 20 and 22 can be rotated about their axes.

A ring protrusion 20 is provided at an axially intermediate portion of the shaft cylinders 20C and 22C.
D and 22D are projected and enter the ring groove formed in the notches 16 and 18. This makes the cutout 1
The light shielding structure prevents external light from entering between the lower case 10 and the upper case 12 from between the shafts 6 and 18 and the shaft cylinders 20C and 22C.

Inside the shaft cylinders 20C and 22C, small cylinder portions 24A and 26A formed at one end of cylindrical spools 24 and 26 that form the main part of the roll-shaped photographic paper supporting means are inserted and fixed. A support shaft 28 is stretched between the spools 24 and 26, and a support cylinder 30 is axially supported at an axially intermediate portion of the support shaft 28. As shown in FIG. 5, the central portion of the leaf spring 31 is fixed to the support cylinder 30 with screws 31A, and the inner periphery of the roll-shaped portion R of the photographic printing paper P inserted into the outer periphery of the spools 24 and 26 is fixed. It is designed to be pressed.

A plurality of ring grooves 32 are formed on the outer circumferences of the spools 24 and 26 so as to accommodate the partition plates 34 and 36. These partition plates 34, 36 have a semicircular shape, and semicircular cutouts 34A, 36A are formed in the axial center portions thereof to serve as accommodating portions for the ring groove 32.

These partition plates 34, 36 are formed in a disc shape in a state of being fitted to each other, but a projection 38 is provided on one of the facing surfaces and a groove 40 for receiving the projection 38 is provided on the other surface.
Are formed. A pin 42 is projected from the groove 40,
It is adapted to be accommodated in an elongated hole 44 formed in the protrusion 38. Therefore, the partition plates 34 and 36 can be brought into and out of contact with each other by an allowable amount of the pin 42 and the long hole 44 in the assembled state, and the tension coil spring 46 stretched between these partition plates 34 and 36. The urging forces of the two bring them closer to each other.

Therefore, the partition plates 34 and 36 are engaged with the ring groove 32 by the urging force of the tension coil spring 46. However, when the width dimension of the printing paper P attached to the spools 24 and 26 is changed, the partition plate 34 is changed. , 36 are spaced apart and accommodated in different ring grooves 32, so that they can be attached to the spools 24, 26 in correspondence with both ends of the photographic printing paper P in the width direction. Therefore, the ring groove 32 is formed at a position corresponding to the printing paper P having different width dimensions.

As shown in FIGS. 3 and 5, a ratchet wheel 48 is fixed to the side surface of the cylindrical spool 24 with a bolt 47. This ratchet wheel 48 is a cylindrical spool 24,
It constitutes a part of a blocking means for blocking the rotation of 26 in the winding direction of the printing paper.

The bottom plate 10A of the lower case 10 as shown in FIG.
Is partially shaped to follow the roll-shaped portion R of the photographic printing paper P, and the support bracket 52 is fixed to the other portion by screws 54. Side plates 56, 58 are formed from the support bracket 52 and are erected parallel to each other with a proper spacing. The upper parts of the side plates 56, 58 are designed to be inserted into the upper case 12.

A winding roller 60, which is one of a pair of rollers, is axially supported near the upper ends of the side plates 56 and 58, and the photographic printing paper P pulled out from the roll-shaped portion R is wound around and reversed, and the bottom plate 10 is rotated.
The opening 10B formed in A and the opening 62A of the light shielding plate 62 attached to the lower surface of the opening 10B are drawn out. A photographic paper drawing portion is provided between the winding roller 60 and the opening 62A.

A pressing roller 64, which is the other of the pair of rollers, corresponds to the winding roller 60, so that the intermediate portion of the photographic printing paper P can be sandwiched. The pressing roller 64 is pivotally supported on one of a pair of moving plates 110 forming a part of the moving means. The moving plate 110 has a substantially triangular shape, and the supporting shaft 1 is provided at the center thereof.

Gears 113A and 113B are attached to the support shaft 112 and the rotary shaft 64A of the pressing roller 64, and these gears 113A and 113B mesh with each other. Thus, when the support shaft is rotated by the handle 68, the gears A, 113
This rotational force is transmitted to the pressing roller 64 via B. Also, the rotating shaft 64A and the gear 113B
Is connected by a one-way clutch (not shown), and when the pressing roller 64 rotates faster than the rotating shaft 64A (when the printing paper reaches the printing apparatus side transport system described later), the two rotate relative to each other. It is supposed to be done.

A connecting pin 114 is fixed to the other side of the movable plate 110, and the connecting pin 114 is inserted into a long hole 118 provided in one side of the arm 116. Arm 1
Reference numeral 16 constitutes a moving means together with the moving plate 110, and the other of the arms 116 is pivotally supported by a bracket 122 attached to the upper case 12 via a shaft 120. Here, when the arm 116 changes from the solid line state in FIG.
The connecting pin 114 inserted into the guide hole is guided and moved from one side of the elongated hole 118 to the other side, and accordingly, the moving plate 110 is rotated around the support shaft 112 in the clockwise direction of FIG. The roller 64 contacts the winding roller 60. Therefore, when the printing paper is wound around the winding roller 60, the printing paper can be sandwiched by the winding roller 60 and the pressing roller 64.

The shaft 120 has a torsion coil spring 1 as a biasing means.
24 is attached, one end of the torsion coil spring 124 to the bracket 122 and the other end to the screw 126.
It is attached to the arm 116 via. As a result, the arm 116 is urged to rotate counterclockwise around the shaft 120 in FIG. 1 (B).

The concave portion 1 is provided on the arm 116 so as to face the upper surface of the upper case 12.
28 is provided and is in contact with the tip of the shaft 130 that constitutes the operation unit. This shaft 130 axially moves in the direction of arrow A in FIG.
6 is moved clockwise from the solid line state in FIG. 1 (B) to the imaginary line state against the biasing force of the torsion coil spring 124.

The shaft 130 has a circular hole 134 provided in the support cylinder 132.
And the other end projects from the upper surface of the upper case 12. In addition, the support cylinder 132 in the shaft 130
A stop ring 136 is attached to the lower end side of the so as to restrict the movement in the axial direction. That is, the torsion coil spring 12
When the arm 116 pushes up the shaft 130 by the urging force of 4, the pushing force is blocked when the retaining ring 136 comes into contact with the support cylinder 132 (see FIG. 1 (B)). Solid state).

The shaft 130 has an operation knob 13 on the side protruding from the upper case 12, which constitutes an operation unit together with the shaft 130.
8 is fixed via screws 140. Operation knob 1
On the back side of 38, that is, on the side facing the support tube 132, large-diameter and small-diameter ribs 142 and 144 are provided upright and a ring-shaped groove 146 is formed. The support cylinder 1 is placed in the groove 146.
32 is inserted to ensure the attachment of the operation knob 138 and to improve the light blocking effect. The upper case 12 is provided with a concave portion 12A, and when the operation knob 138 is pressed, the concave portion 12A enters the concave portion 12A, and at the same time, the shaft 130 moves axially (moves in the direction of arrow A in FIG. 1 (B)).
Then, the arm 116 can be brought into the imaginary line state of FIG. 1 (B). This axial movement is the same as the direction in which the magazine is loaded into the printing apparatus 103 (see FIG. 1A).

Both end portions of a mounting bar 70 shown in FIG. 4 are fixed to the side plates 56 and 58. The mounting bar 70 has a plurality of mounting holes 72 formed in the middle thereof, and a screw 74 passing through the mounting hole 72 is provided with a pair of guide brackets 76, 78.
These guide brackets 76 by tightening
78 can be supported. As shown in FIG. 4, these guide brackets 76 and 78 are thin plate materials bent in a U-shape to prevent the photographic paper P from meandering in correspondence with both sides of the photographic paper P. There is. For this reason, the guide brackets 76 and 78 are designed so that the mounting positions of the screws 74 in the mounting holes 72 are always changed so as to correspond to both sides of the printing paper P. The mounting holes 72 are formed at predetermined positions so that the guide brackets 76 and 78 can be mounted in correspondence with the preset width dimensions of the plurality of printing papers P.

A rotary shaft 82 is penetratingly supported by the side plates 56 and 58,
One end of the rotating arm 84 is fixed to the middle portion in the longitudinal direction. The side wall 56 of the rotary arm 84 is arranged so that the tip of the rotary arm 84 is always pressed by a light biasing force to the photographic printing paper P linearly arranged between the winding roller 60 and the opening 62A.
A torsion coil spring 90 (see FIG. 3) is interposed between and. Therefore, the photographic paper P is wrapped around the winding roller 60 and the opening 62.
The rotation arm 84 is in the imaginary line state of FIG. 1 (A) when it is interposed between A and A, and the solid line of FIG. 1 (A) when the printing paper P is not interposed in this portion. It becomes a state.

One end of the connecting arm 92 is fixed to one end of the rotating arm 84 in the axial direction. A claw 94 is formed at the tip of the connecting arm 92 and corresponds to the ratchet wheel 48 of the cylindrical spool 24 that supports the rolled photographic paper.

Therefore, when the drawing paper P is present in the drawer of the connecting arm 92, the connecting arm 92 is pushed out by the printing paper P to the imaginary line state of FIG.
4 is separated from the ratchet foil 48, but when the front end portion of the photographic printing paper P is pulled into the lower case 10 by a predetermined amount, the torsion coil spring 90 rotates clockwise in FIG. It engages with the ratchet wheel 48 to prevent the roll-shaped portion R from rotating in the winding direction (clockwise rotation in FIG. 1A).

It should be noted that guide plates 96 and 97 as shown in FIG. 4 are arranged on both sides of the movement locus of the photographic paper drawing portion to which the rotary arm 84 corresponds, and the guide plate 97 includes a part of the rotary arm 84. An opening 96A for allowing passage is formed. A roller 98 is axially supported on the guide plate 97 corresponding to one side of the printing paper passing therethrough.
When there is no printing paper, the tip of the rotating arm 84 approaches the small diameter portion 98A of the roller 98.

As shown in FIG. 1 (A), a release block 99 is arranged on one side of the connecting arm 92, and a pin 100 protruding from the release block 99 is pivotally supported on the lower case 10. The release block 99 receives a rotational force in the counterclockwise direction in FIG. 1 (A) by the urging force of a torsion coil spring (not shown), and forcibly rotates the connecting arm 92 in the counterclockwise direction in FIG. 1 (A). And has a role as a releasing means for separating the claw 94 from the ratchet wheel 48. The releasing block 99 corresponds to the releasing projection 101 as shown in FIG. The releasing projection 101 is attached to a part of the upper case 12, and is released when the upper case 12 is rotated clockwise around the hinge 14 in FIG. The release block 99 is separated from the block 99 and can be rotated counterclockwise by the urging force of the torsion coil spring.
In the state shown in FIG. 1 (A) in which the lower case 10 is fitted to the lower case 10, the release block 99 is rotated clockwise around the pin 100 to a position not corresponding to the connecting arm 92.

A guide bracket 102 is attached to the bottom plate 10A so that the opening 62A and the printing paper guide 10 of the printing apparatus 103 can be installed.
The photographic printing paper P is guided between it and 3A, and the light shielding plate 62 is slidably held between it and the bottom plate 10A.

The light shielding plate 62 makes the opening 10B in a light shielding state by interposing the compression coil spring 106 between the light shielding plate 62 and the lower case 10. However, when the lower case 10 and the upper case 12 are mounted on the printing apparatus 103, this printing is performed. The front end of the block 108 protruding from the device 103 is moved against the biasing force of the compression coil spring 106 corresponding to the inclined portion 62B, so that the opening 62A can move the printing paper P corresponding to the opening 10B. The configuration is

Next, the operation of this embodiment will be described.

Printing paper P with this magazine removed from the printing device
The upper case 12 is relatively rotated with respect to the lower case 10 to be opened. Therefore, the release projection 101 is separated from the release block 99, and the release block 9 is released.
9 is rotated counterclockwise in FIG. 1 (A) by the urging force of a torsion coil spring (not shown), and the connecting arm 92 is rotated by the rotating shaft 8
Since it is rotated in the counterclockwise direction in FIG.
4 is separated from the ratchet wheel 48, and the roll-shaped portion R becomes rotatable.

After removing the roll-shaped portion R, a new roll-shaped portion R is attached to the outer circumferences of the cylindrical spools 24 and 26 and the support cylinder 30, and the rotary dials 20 and 22 are fitted into the notches 16. Here, when the upper case 12 is tightly closed to the lower case 10, the rotary dials 20 and 22 also come into contact with the notches 16 so that the lower case 10 and the upper case 12 are shielded from light. Before the lower case 10 and the upper case 12 are closed, the photographic printing paper P pulled out from the roll-shaped portion R is wound around the winding roller 60 and inverted, and the vicinity of the leading end is guided by the guide plates 96, 97 and the guide bracket 76. , 78 to contact the light shielding plate 62. Therefore, the rotating arm 84 is maintained in the state of being rotated counterclockwise in FIG. 1 (A) by the rigidity of the printing paper drawing portion. Therefore, even when the upper case 12 is closed to the lower case 10 and the release projection 101 rotates the release block 99 to the state shown by the solid line in FIG. 1 (A), the connecting arm 92 has the connection arm 92 shown in FIG. 1 (A). Keep the imaginary line, nail 94
Does not engage the ratchet foil 48.

Here, the lower case 10 and the upper case 12 are loaded into the printing apparatus 103. For this reason, the block 1 protruding from the printing device
Reference numeral 08 moves the light shielding plate 62 against the biasing force of the compression coil spring 106 to open the opening 10B. Here, the worker carries out the work of feeding the leading end of the printing paper to the printing apparatus 103. In this state, however, the winding roller 60 and the pressing roller 64 are separated from each other, so that the handle 68 is rotated. However, the conveying force is not transmitted to the photographic paper. The procedure for feeding the printing paper to the printing apparatus 103 will be described in detail below.

First, when the loading of the magazine into the printing apparatus is completed as described above, the worker presses the operation knob 138 installed on the upper surface of the upper case 12. This pressing force is transmitted to the shaft 130, and the shaft 130 axially moves in the direction of arrow A in FIG. 1 (B). Since the axially moved tip of the shaft 130 is in contact with the concave portion 128 of the arm 116, the movement of the shaft 130 causes the arm 116 to resist the urging force of the torsion coil spring 124 and move around the shaft 120.
It rotates clockwise in the figure (B). Accordingly, the long hole 11
8 is guided and moved from one side of the elongated hole 118 to the other side, and the movable plate 110 is moved to the support shaft 112.
Is rotated in the clockwise direction in FIG. 1 (B). As a result, the pressing roller 64 is moved in the direction in which it comes into contact with the winding roller 60, and the photographic paper wound around the winding roller 60 can be held by the winding roller 60 and the pressing roller 64. When the handle 68 is rotated in this state, the support shaft 11
2 and the rotating shaft of the pressing roller 64 are gears 113A, 113
Since they are connected by B, a conveying force can be applied to the printing paper.

The leading end of the photographic printing paper to which the carrying force is applied is sent to the printing apparatus through the opening 10B, reaches the printing apparatus side carrying system, and is thereafter moved by the printing apparatus side carrying system.

As described above, in this embodiment, the operation direction for imparting the conveying force to the printing paper in the magazine is the same as the loading direction of the magazine in the printing apparatus, so that the loading of the magazine in the printing apparatus is ensured. You can Further, since the one-way clutch is interposed between the rotating shaft 64A and the gear 113B, the impact immediately after reaching the conveying system on the side of the printing apparatus is affected by the gear 11
Since it is not transmitted to the handle 68 by the relative rotation of 3B and the rotating shaft 64A, there is no danger in the operation of the worker.

The printing device 103 pulls in the printing paper P and performs a predetermined amount of printing work, but since there is no portion in the drawing-out portion of the printing paper that causes a large resistance, the drawing operation is smooth and there is no meandering or the like. When it becomes necessary to mount a magazine containing another printing paper, the magazine set in the printing apparatus 103 is removed. In this case, rotate the dial 2 before removing this magazine from the printing device 103.
0 and 22 are reversed and the photographic paper P is drawn into this magazine.

When the front end of the photographic paper P passes near the front end of the rotary arm 84, the rotary arm 84 is moved by the urging force of the torsion coil spring 90 within the movement locus of the photographic paper P as shown by the solid line in FIG. And the connecting arm 92 has a claw 94.
Is engaged with the ratchet foil 48, so that the roll portion R is prevented from winding. For this reason, the worker is
Can detect the state that the
The application of rotational force to the rotary dials 20 and 22 is stopped.

Here, when the worker removes this magazine from the printing apparatus, the light shielding plate 62 separates from the block 108, so the opening 10B is automatically closed by the urging force of the tension coil spring 106.

After that, the worker may supply the magazines containing the printing papers P having different widths to the printing apparatus by the same operation as described above.

For this reason, the removed magazine can be set again in the printing apparatus by the same procedure when it is reused, and the photographic printing paper P is stored in the magazine at the time of removal so that the photographic printing paper P is not fogged. The printing paper P can be used without waste. Further, since the intermediate portion of the photographic printing paper P is between the winding roller 60 and the pressing roller 64, the leading end of the photographic printing paper P can be easily sent out to the printing apparatus by the rotation of the handle 68 during reuse.

[Effect of device]

As described above, the photographic printing paper magazine according to the present invention is
This has an excellent effect that the printing paper can be properly sent to the printing apparatus main body when the printing paper is pulled out after the magazine is loaded, and that the printing paper is not meandered during the printing process.
