DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a recording material magazine for accommodating a recording material roll, which is used for an image recording apparatus using a recording material.

[0002]

2. Description of the Related Art Various recording materials such as silver halide photographic light-sensitive materials, heat-developable light-sensitive materials, and light- and heat-sensitive recording materials are used in image recording apparatuses such as printers and copiers. Such a recording material may be cut into a predetermined length in advance and supplied to an image recording apparatus.However, the recording material is wound into a recording material roll while being kept in a long length, and the recording material roll is supplied to the apparatus as it is. Many are supplied and cut to a size corresponding to the hard copy created in the image recording apparatus. In many cases, the recording material roll is stored in a predetermined magazine and is loaded at a predetermined position of the image recording apparatus.

For example, a photo printer (photo printing device)
Then, the photosensitive material roll is stored in a predetermined magazine, the magazine is loaded into a predetermined position of the apparatus, the photosensitive material is pulled out of the magazine, cut into a predetermined length corresponding to a print size, and then transported along a predetermined path. Exposure, development and drying to give (finished) prints, or
While being long, it is transported along a predetermined path and subjected to processes such as exposure, development, and drying, and finally cut into one print.

In an image recording apparatus using such a recording material roll, if the position of the recording material supplied from the magazine in the direction perpendicular to the conveying direction (hereinafter, referred to as the width direction) is out of order, the recording material will meander. If the transport guide is not arranged, the downstream of the transport direction (hereinafter, referred to as
The conveyance gradually shifts in the width direction toward the downstream side (to cause skew). For this reason, the recording material roll is held by being inserted through a shaft held by a spool held at a predetermined position in the magazine, and is also sandwiched by flanges engaged with the spool to regulate the position in the width (axis) direction. It is loaded at a predetermined position in the magazine.

FIG. 3 shows an example of a spool and a flange for holding a photosensitive material roll Ar around which a long photosensitive material A is wound. As described above, the photosensitive material roll Ar is inserted into the shaft core and held by the cylindrical spool 104,
The position in the width direction is regulated so as to be sandwiched between the flanges 106 and 106 from both sides in the axial direction.

A large number of photosensitive material rolls Ar having various sizes (width of the photosensitive material A to be wound) are prepared. In the illustrated example, three types (a total of six) of locking grooves 104a and 104b are formed on the spool 104 at intervals corresponding to the width of each photosensitive material roll Ar.
And 104c are formed. Each locking groove has a width corresponding to the thickness of the flange 106 to loosely fit the flange 106, and is located between the center of conveyance of the photosensitive material A (the center in the direction perpendicular to the conveyance direction) and the two grooves. The points are formed so as to coincide with each other. On the other hand, a through-hole 108 </ b> A that is inserted into the spool 104 is formed in the flange 106. A part of the through-hole 108 </ b> A is constituted by a locking member 108 which is a plate material coplanar with the flange 106. The locking member 108 is held by the flange 106 so as to be movable in the vertical direction (the direction of arrow a) in the figure, and is urged downward by a known means such as a spring.

That is, in the illustrated example, the locking member 1
08 is lifted upward, the spool 104 is inserted into one flange 106, and the photosensitive material roll Ar to be used is used.
By inserting and engaging the locking member 108 in the locking groove corresponding to the width of the flange, one flange 106 is positioned and held on the spool 104. Next, the spool 104 is inserted through the axis of the photosensitive material roll Ar, and finally, the other flange 106 is positioned and held on the spool 104 in the same manner as the above. Thus, the photosensitive material roll Ar is positioned in the width direction by the two flanges 106 and is held on the spool 104.

Therefore, in the conventional magazine, each time the size of the stored photosensitive material roll Ar changes, the spool 10
It is necessary to change the attachment position of the flange 106 to the photosensitive material roll 4, and it takes time and effort to replace the photosensitive material roll Ar.

In the illustrated example, the photosensitive material rolls A of three sizes are provided on the spool 104 in order to make the configuration clear.
Although only the locking groove corresponding to r is shown, in practice, the photosensitive material roll Ar is often prepared in various sizes according to the size of the print (hard copy) to be created. For example, if it is a photographic material (photographic paper),
89mm, 10mm for various standard size prints
2mm, 127mm, 130mm, 152mm, 165mm, 17
Photosensitive material rolls Ar having a size of 8 mm, 203 mm, 210 mm, etc. are known. Therefore, the magazine preferably corresponds to the photosensitive material rolls Ar of all the sizes, which results in the spool 104 having a very large number of locking grooves.

However, when a large number of locking grooves are formed in the spool 104, it is easy to make a mistake that the flange 106 is engaged with a locking groove different from a predetermined position. In particular, in the photographic light-sensitive material, 127 mm and 130 mm, and 203 mm and 21 mm
In many cases, such as 0 mm, the locking grooves are extremely close to each other, and such mistakes are likely to occur. Flange 106
Is different from the predetermined position, an error occurs in the position of the photosensitive material roll Ar in the axial direction, and meandering and skew occur, which causes jamming.
After confirming, it is necessary to install it in the correct position
This is a cause of further lowering workability.

Further, in order to stably produce an appropriate print, it is necessary to be able to determine the size of the recording material roll stored in the magazine. In particular, it is necessary to shield the inside of a magazine of photosensitive material from the outside, and it is difficult to confirm the inside from outside. Therefore, it is necessary to be configured so that the size of the photosensitive material to be stored can be determined from outside. Therefore, for example, in a conventional magazine for photosensitive materials, a maximum of 4
A detection member having a number of pins (ie, 4 bits) is created for each type of photosensitive material roll, and a detection member corresponding to the photosensitive material roll to be stored is attached to a predetermined position outside the magazine.
By using a microswitch or the like, where the detection member has the pin is detected, and the size or the like of the photosensitive material roll Ar stored in the magazine is detected. Therefore, every time the size of the photosensitive material roll Ar changes, it is necessary to remove the detection member and attach a detection member corresponding to the photosensitive material roll Ar to be stored.
Replacement work is troublesome.

[0012]

Note that, in addition to the members shown in the drawing, various members such as a conveyance unit for the photosensitive material A such as a conveyance roller, a conveyance guide, and a sensor are arranged as necessary.

In the printer 10, the photosensitive material supply unit 1
2 (hereinafter, referred to as a supply unit 12) includes loading units 20 and 2
2, a pair of pull-out rollers 24 and 26, and a cutter 28
And 30. Loading sections 20 and 2
Reference numeral 2 denotes a magazine 32 in which a photosensitive material roll Ar formed by winding a long photosensitive material A into a roll is housed in a light-shielding housing.
Is the part to be loaded. In the printer 10 of the illustrated example, the loading section 20 includes a photosensitive material roll A at a position corresponding to the detection plate 70 of the magazine 32 loaded at a predetermined position.
A sensor 52 for reading display means 86 having information on the size r (width of the photosensitive material A to be wound) is arranged, and a similar sensor 54 is arranged on the loading section 22, respectively. The magazines 32 loaded in the loading units 20 and 22 are usually wound with photosensitive materials A of different types such as width (size), surface type (silk or mat, etc.), specifications (thickness, base type, etc.). The photosensitive material roll Ar is stored. Here, the magazine 32 is a recording material magazine of the present invention (hereinafter, referred to as a magazine).
Magazine).

FIG. 2 is a schematic diagram of the magazine 32. In FIG. 2, (a) is a side view, (b) is a view when the inside of the magazine is opened and viewed from the side opposite to the discharge port, and (c) is a side surface of the spool (the side opposite to (a) above). FIG.

The illustrated example magazine 32 includes a lower case 6.
2, upper case 64, spool 66, two flanges 6
8, a detection plate 70, and a knob 72.

In the magazine 32, the main body of the magazine (light-shielding case) is constituted by combining a lower case 62 and an upper case 64, which are open-sided cases, and the photosensitive material A is provided at both upper corners. A slit 74a of the discharge portion 74 formed by the case so as to protrude in the discharge direction.
Is discharged from Lower case 62 and upper case 64
Are rotatably engaged with each other by a hinge 78 disposed on a side diagonally opposite to the discharge portion 74.
By rotating the upper case 64 in the direction of arrow a with respect to 2, the interior is opened or closed as shown in FIG.

On the side of the lower case 62 that contacts the upper case 64, there are formed support portions 62a and 62b on which both ends of the spool 66 are mounted and rotatably supported.
Inside the lower case 62, a spool 6 is provided by a knob 72.
A stopper 76 is disposed to prevent the flange 68 from rotating when the wheel 6 is rotated. In addition, the upper case 64 is formed with a support portion rotatably supporting both ends of the spool 66 together with the support portions 62a and 62b of the lower case 62. Therefore, the spool 66 (and the flange 68)
Can be mounted by opening the upper case 64.

The photosensitive material roll Ar is held by being penetrated through the axis by a spool 66 and has flanges 68 and 6.
8 to define the position in the width (axial) direction. The photosensitive material roll Ar held by the spool 66 and the flange 68, as described above,
6 are supporting portions 62a and 62b of the lower case 62.
Is stored in a predetermined position in the magazine 32.

In the magazine 32, a spool 66 is a substantially columnar member having a thickness that can rotate through the photosensitive material roll Ar without play according to the thickness of the axis of the photosensitive material roll Ar.
It has threaded portions 80 and 82 which are separated in the width direction and are formed in different directions. At one end of the spool 66, a knob 72 for rotating the spool 66 is fixed so as to be outside the lower case 62. Inside the knob 72, a disk-shaped detection having the same center is provided. The plate 70 is fixed. The detection plate 70 will be described later in detail. In the spool 66, a screw portion 82 on the opposite side of the knob 72 is a double tube, and the screw portion 82 is
The core 84 is loosely fitted to the core 84 so that it can be freely extracted. FIG.
As shown in (c), a spline 82a extending in the width direction is formed inside the screw portion 82, and a concave groove 84a engaging with the spline 82a is formed in the core 84, respectively. Therefore, the screw portion 82 is connected to the spool 66 (the core 8
From 4), it can be removed in the width direction, but is fixed in the rotation direction.

On the other hand, the flange 68 is a disk-shaped member having a through hole at the center. The through-hole is formed as a screw, and the flange 68 is screwed one by one to the screw portions 80 and 82 and held on the spool 66. In addition, flange 6
8 is formed with a notch that engages with a stopper 76 of the lower case 62. Therefore, by engaging the notch of the flange 68 with the stopper 76 and pivotally supporting the spool 66 on the supporting portions 62a and 62b of the lower case 62 and rotating the knob 72, the spool 68 contacts each other without rotating the flange 68. You can release. As will be described later, in the illustrated printer 10, a latent image is recorded on the photosensitive material A by light beam scanning exposure with the center of the photosensitive material A being aligned with the center in the scanning direction, that is, the so-called center. Therefore, the two flanges 68 are screwed into the threaded portions 80 and 82 such that the middle point thereof is the center (hereinafter, referred to as the transport center) in the direction orthogonal to the transport (drawing) direction of the photosensitive material A. I do.

In setting the photosensitive material roll Ar in such a magazine 32, if necessary, the knob 72 is rotated to separate the two flanges 68, and then the upper case 64 is opened. The spool 66 (and the flange 68) is removed from the lower case 62, and the screw portion 82 is removed from the core 84 of the spool 66. Next, the shaft core of the photosensitive material roll Ar to be used next is set by passing through the spool 66, and the screw portion 82 is inserted into the core 84 again and pushed into a predetermined position. Thereafter, the notch of the flange 68 is engaged with the stopper 76, and both ends of the spool 66 are pivotally supported by the support portions 62a and 62b of the lower case 62, the photosensitive material A is pulled out to a predetermined position, and the upper case 64 is closed. Then, the knob 72 is moved in the direction in which the flange 68 approaches.
At the time when the knob 72 stops rotating (ie,
At the time when both flanges 68 contact the end surfaces of the photosensitive material roll Ar), the photosensitive material roll Ar is set at a predetermined position in the magazine 32. That is, according to the present invention, the work such as the position adjustment of the flange 68 is easy, and even if the photosensitive material roll Ar is different in size from the front, it can be easily set in the magazine.

Here, as described above, the disk 72 has a disk-shaped detection plate 70 fixed to the knob 72. Also,
In the printer 10, sensors 52 and 54 are arranged at positions corresponding to the detection plates 70 of the magazines 32 loaded at predetermined positions of the loading units 20 and 22, respectively. Further, the flange 68 is not removed from the threaded portions 80 and 82 that are screwed together, and is located such that an intermediate point between the two becomes the transport center. Therefore, which position of the detection plate 70 is
Whether it comes to the position corresponding to the detection by 2 (54) depends on the position (interval) of the two flanges 68, that is, the size of the photosensitive material roll Ar.

In the magazine 32 of the present invention, a detection plate 70 which rotates together with the spool 66 is provided.
0, that is, when the photosensitive material roll Ar is set as described above, the sensor 52 (5
A display means 86 having information on the size of the photosensitive material roll Ar is provided at a position corresponding to the reading in 4). Thereby, without opening the magazine 32,
The printer 10 and the operator can detect the size of the photosensitive material roll Ar. In the illustrated example, there are five display means 86a to 86e corresponding to the sizes of various recording material rolls Ar, and each carries information on the size of the photosensitive material roll Ar. For example, if the size of the photosensitive material roll Ar in the illustrated example is 127 mm,
At this time, the display means 86a provided at a position corresponding to the sensor 52 indicates that the photosensitive material roll Ar is 127 mm.
It has information indicating the size. The sensor 5
The information of the photosensitive material roll Ar size read by the second or the like is transferred to a necessary portion of the printer 10.

The display means 86 is not particularly limited, and may be appropriately selected according to the sensor 52 (or the sensor is determined according to the display means). For example, a combination of a bar code as the display unit 86 and a bar code reader as the sensor 52, a combination of a plurality of pins and a microswitch as described above, a combination of a magnetic recording medium and its reading unit, and the like are exemplified. You. If necessary, the size of the corresponding photosensitive material roll Ar may be described on the display means 86 so that the operator can confirm it from outside the magazine, or only the size may be described. In the illustrated example of the printer 10, the number of sensors 52 (54) is one in each loading unit. However, if necessary, a plurality of sensors are provided at different positions corresponding to the detection plate 70, and the display means 86 is provided. You may make it read.
Thereby, it is possible to cope with more sizes of the photosensitive material roll Ar.

In the illustrated example, the photosensitive material roll A
Although the spool 66 and the flange 68 do not rotate together with the rotation of the photosensitive material A, the surface of the spool 66 (or the axis of the photosensitive material roll Ar) can be made smoother in applications that require smoother discharge of the photosensitive material A. To make something better,
The smoothness of the drawer may be improved by a method in which the flange is doubled and the inner flange is configured to rotate together with the photosensitive material roll Ar.

After the magazine 32 is loaded into the printer 10 and the size of the photosensitive material roll Ar is detected, the engagement between the stopper 76 and the flange 68 is released, and the spool 66 and the flange 68 rotate together with the photosensitive material roll Ar. May be configured. At this time, the detection plate 70 is also rotated by pulling out the photosensitive material A. For example, once the magazine 32 is loaded, the size of the detected photosensitive material roll Ar is stored until the magazine 32 is removed. If necessary, the size of the photosensitive material roll Ar may be detected by a method such as displaying the information on a display of the printer 10 as necessary.

In the illustrated magazine 32, the spool 66 is formed as a double tube at the screw portion 82, the flange 68 is removed, and the photosensitive material roll Ar can be set. However, the present invention is not limited to this. Instead, the photosensitive material roll Ar may be set on the spool 66 by, for example, a method in which the spool is formed of two cylinders that can be joined / removed at an intermediate portion.

Since the printer in the illustrated example performs exposure on the basis of the center, the photosensitive material roll Ar is also arranged so that the center in the width direction is coincident with the transport center. However, the present invention is not limited to a printer that performs exposure on the basis of the center. In addition, the present invention is also applicable to a printer that performs exposure and transport using the end surface of the photosensitive material A as a reference (a so-called edge reference). In this case, it is not always necessary to provide two flanges. For example, a reference surface with which the end surface of the photosensitive material roll Ar abuts is formed in the magazine main body, and this is used as a flange instead, and one flange has a width. The photosensitive material roll Ar may be set at a predetermined position by moving in the direction.

The pull-out roller pairs 24 and 26 pull out and transport the photosensitive material A stored in the magazine 32 loaded in the loading units 20 and 22. This conveyance stops when the length of the photosensitive material A conveyed downstream from the corresponding cutters 28 and 30 reaches a length corresponding to the print (recorded image) to be produced, and then the cutters 28 and 30 operate. Then, the photosensitive material A is cut into a cut sheet having a predetermined length.

The photosensitive material A pulled out of the magazine 32 of the loading section 22 and cut to a predetermined length by the cutter 30
The photosensitive material A pulled out of the magazine 32 of the loading unit 20 and cut by the cutter 28 on the other hand is transported by the first transport unit 34 and the second transport unit 36 composed of a number of transport roller pairs. By 36, both are conveyed upward, then conveyed rightward, and conveyed to the image recording unit 16 (scanning conveyance unit 42) with the recording surface facing up.

In the middle of the second transport section 36, the back printing means 1
4 are arranged. The back printing means 14 records various information such as a photographing date, a print printing date, a frame number, a film ID number, etc., a so-called back print on the non-recording surface (non-emulsion surface = back surface) of the photosensitive material A (back printing). The back-printing unit 14 records a back print of the photosensitive material A while being transported by the second transport unit 36.

A loop forming section 38 is provided between the pair of transport rollers 36a and the pair of transport rollers 36b downstream of the back printing means 14 of the second transport section 36. That is, the second
The transport speed of the photosensitive material A in the transport unit 36 is the same as that of the image recording unit 1 after the transport roller pair 36a downstream of the loop forming unit 38.
6 (scanning conveying means 42), the speed is set higher than that before the conveying roller pair 36b upstream of the loop forming section 38, and the photosensitive material A conveyed through the second conveying section 36 In the loop forming unit 38, as indicated by a dotted line in the drawing, due to the difference in upstream and downstream transport speeds,
A loop corresponding to the size is formed. In the illustrated example of the printer 10, the back printing unit 14 and the image recording unit 16 are separated from each other with a short path length, and highly accurate scanning and transport of the photosensitive material A during exposure is realized.

The photosensitive material A is supplied from the second transport section 36 to the image recording section 16. The image recording unit 16 (hereinafter, referred to as the recording unit 16) includes an exposure unit 40 and a scanning and conveying unit 42, and scans with the light beam L while conveying the photosensitive material A in the sub-scanning direction. Thus, the photosensitive material A is two-dimensionally scanned and exposed to record a latent image.

The exposure unit 40 modulates according to the recorded image and deviates in the main scanning direction.
A light source for each light beam that is incident on a predetermined recording position X and scans and exposes the photosensitive material A with the center in the main scanning direction coincident with the center in the width direction of the photosensitive material A on the basis of a center; , A known optical beam scanning device including a light beam modulating unit, an optical deflector such as a polygon mirror, an fθ lens, a mirror for adjusting an optical path, and the like.

On the other hand, the scanning / transporting means 42
A pair of conveyance rollers arranged with the (scanning line) interposed therebetween;
An exposure guide (not shown) for suitably holding the photosensitive material A at the recording position X, and a sub-scanning direction orthogonal to the main scanning direction by a pair of conveying rollers while holding the photosensitive material A at the recording position X Material A is scanned and transported. As described above, since the light beam L is deflected in the main scanning direction, the photosensitive material A is two-dimensionally scanned and exposed by the light beam L modulated according to an image to be recorded, and a latent image is recorded. Is done.

The photosensitive material A on which the latent image has been recorded by the recording unit 16 is conveyed to a distribution unit 18 disposed downstream.
The distribution unit 18 distributes the exposed photosensitive material A in a direction perpendicular to the transport direction according to a sequence appropriately determined according to the size and the like, and forms a plurality of rows overlapping in the transport direction. By transporting the photosensitive material A to the pair of transport rollers 44 for supplying the photosensitive material A to the processor P, the processing capacity of the processor P is improved, for example, about two times for two rows and about three times for three rows.

The distributing section 18 in the illustrated example includes a belt conveyor 46 for placing and transporting the photosensitive material A, and a distributing device 48 disposed thereon. The distributing device 48 has two suction units 50 arranged orthogonally to the direction of conveyance by the belt conveyor 46. The suction units 50 adsorb and hold the photosensitive material A and lift it.
One is conveyed diagonally right downstream in the conveying direction of the belt conveyor 46, and the other is conveyed diagonally downstream in the same left direction, and the photosensitive material A is sorted left and right to form a plurality of rows.

The photosensitive material A conveyed by the distribution unit 18
Is supplied to the processor P by a pair of downstream conveying rollers 44, subjected to development processing such as color development, bleach-fixing, and washing with water, dried, and discharged as a (finished) print.

Although the recording material magazine of the present invention has been described in detail, the present invention is not limited to the above examples.
Of course, various improvements and changes may be made without departing from the spirit of the present invention.
