Here, as described above, the magazine currently used in the photo printer is provided with two hands for fixing the flange at a predetermined position corresponding to the width of the photosensitive material when mounting the photosensitive material roll. In addition, it is necessary to work by groping in a dark box, a dark bag, or a dark room, and there is a problem that it is difficult to mount the flange. In view of the above, the present invention solves the above-mentioned problem by adopting a configuration in which the flange can be attached to the spool with one hand as the engagement means.

Specifically, as shown in FIGS. 3A and 3B, the spool 66 has a positioning hole 66a.
And a rotation preventing portion 66b, and the flange 68 is provided with a mounting portion 80 for attaching the flange 68 to a predetermined position of the spool 66.

The positioning hole 66a is a hole for fixing the position of the flange 68 in the rotation axis direction (axial direction) by inserting the pin 84, and is a counter electrode position on the outer periphery of the spool 66. Are formed in pairs at positions 180 degrees apart from each other (accordingly, at two places in the same cross section), and at a plurality of places in the direction of the rotation axis in accordance with various photosensitive material sizes (widths) to be used. Is formed. The positioning hole 66a is not particularly limited as long as the pin 84 can be inserted therein, and may be formed in various shapes and sizes. The rotation preventing portion 66b is provided with a spool 66.
In order to prevent only the rotation of the flange 68 with respect to the spool 68, the flange 68 is fixed to the spool 66 only in the rotation direction, together with an engagement portion 86 of the flange 68, which will be described later. It constitutes a rotation preventing structure for enabling movement, and is formed in a groove shape on the outer periphery of the spool 66 in parallel with the rotation axis of the spool 66. The rotation preventing portion 66b may have any shape as long as it is slidable only in the rotation axis direction while at least engaging with the engaging portion 86 of the mounting portion 80. , A convex shape or a combination thereof can be adopted.

The mounting portion 80 is provided on the flange 68 for mounting the flange 68 at a predetermined position on the spool 66. The mounting portion 80 includes a tension member 82, a pin 84, an engaging portion 86, and a biasing means 88. And Tension member 82,
Reference numeral 82 denotes a member that allows the pin 84 to be easily and reliably inserted into and removed from the positioning hole 66a by manual operation (one hand). 2 in total) are provided so as to be slidable in the radial direction of the flange 68, and each has at least one finger 1.
The book has, for example, concave portions 82a, 82a on which a thumb can be hung on one side and a middle finger can be hung on the other. Such recesses 82a,
82a may be formed in such a direction and shape that the user can easily put his / her finger on both recesses 82a, 82a with one hand when attached to the flange 66. It is preferable to form the groove-shaped recesses 82a, 82a in a direction perpendicular to the radius of 68, since both recesses 82a, 82a are parallel to each other, so that a finger can be easily placed and the user can easily operate with one hand.

The tension member 82 includes the flange 6

It is also possible to adopt a configuration formed in a shape, and various configurations can be adopted, and there is no particular limitation.

The engaging portion 86 holds the flange 68 in a predetermined direction with respect to the outer peripheral direction of the spool 66 by being engaged with the rotation preventing portion 66b, and can be moved only in the rotational axis direction of the spool 66. The hole 66a of the pin 84
It is a portion for facilitating insertion into the rotation preventing portion 66b, and has a convex shape or a concave shape which can be engaged with the rotation preventing portion 66b. The engaging portion 86 in the illustrated example is formed in a ring shape along the through hole of the flange 68, and has a projection 86a engageable with the rotation preventing portion 66b, and tension members 82, 82.
And a notch 86b that allows the ingress and egress of the notch. In this way, the mounting portion 80 is
6 and has a sufficient area, so that the flange 6
8 can be engaged with the spool 66 with sufficient stability. Further, since the rotation direction of the flange 68 with respect to the spool 66 is securely fixed, the urging force of the urging means 88 described later can be set small.
It is possible to easily perform the operation with only one hand. The configuration of the engaging portion 86 is not limited to the illustrated example, and various configurations are possible as long as at least a member having a convex or concave shape capable of engaging with the rotation preventing portion 66b is provided on the flange 68. Can be adopted. In addition, flange 6
The rotation prevention portion 66 of the spool 66
A concave portion or a convex portion engaging with b may be provided as the engaging portion 86.

The urging means 88 urges the tension member 82 in the direction of the center of the flange 68, thereby (the tension member 82
The pin 84 (at the tip) is inserted into the positioning hole 66a of the spool 66.
A known biasing member such as a tension spring can be used, and is not particularly limited. In addition, the method of attaching the biasing means 88 is not particularly limited, and various methods can be adopted. For example, as shown in the illustrated example, the outside of the tension member 82 (the side opposite to the side on which the pin 84 is provided) ), An urging means 8 which is a tension spring
In a state in which the tension member 8 is stretched, both ends thereof are respectively
2 may be fixed to the engaging portions 86 near both sides. Further, the tension member 82 and the engagement portion 86 are biased by the urging means 88.
Or a configuration in which the urging means is embeded in the joint portion between the tension member 82 and the flange 68 so as to extend and contract. In FIG. 3A, the urging member 88 is omitted to clearly show the structure.

The basic structure of the recording material magazine according to the present invention is as described above. Hereinafter, a method for mounting the photosensitive material A and the flange 68 in this magazine will be described. First, the flange 68 on one side is set. More specifically, the user opens the pin 84 by positioning the pin 84 by lightly opening the two concave portions 82a, 82a with fingers.
Remove from a. In this state, the engaging portion 86 is inserted into the rotation preventing groove 6.
6b, the flange 68 is inserted into the spool 66, and when the flange 68 is moved to a position corresponding to the desired width of the photosensitive material, the finger is released from both the concave portions 82a, 82a. At this time, the pin 84 is inserted into the positioning hole 66a by the urging force of the urging means 88, and the position of the flange 68 in the rotation axis direction is fixed. This one side flange 6
The setting of 8 can be performed in a light room. Next, with the flange 68 on one side set in this way, the spool 66 is brought into a dark bag, a dark box, or a dark room, and is inserted through the shaft of the photosensitive material roll Ar, thereby causing the photosensitive material roll Ar to pass through. Ar is set on the spool 66.

Subsequently, the other flange 68 is set. Specifically, the user inserts the flange 68 into the spool 66 by engaging the engaging portion 86 with the rotation preventing groove 66b with the pin 84 removed from the positioning hole 66a as described above. Next, the photosensitive material roll A
r, the two concave portions 82a,
Release your finger from 82a. At this time, the pin 84 is
8, is inserted into the positioning hole 66a by the urging force,
The position of the flange 68 in the rotation axis direction is fixed, and the attachment of the photosensitive material A and the flange 68 to the spool 66 is completed. As described above, in the photosensitive material magazine of the present invention, the flange 68 can be attached to the spool 66 by one-handed operation. Therefore, even in a dark box, a dark bag, or a dark room for securing light shielding properties, It is possible to perform a reliable operation with an extremely simple operation.

Since the printer in the illustrated example performs exposure on the basis of the center, in the magazine 32, the photosensitive material roll Ar is arranged so that the center in the width direction is coincident with the conveyance center. In addition to a printer that performs exposure based on a reference, 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, only one of the flanges 68 can be moved in the rotation axis direction of the spool 66, and the attachment portion 80 according to the present invention may be provided.

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 conveying rollers 36a and the pair of conveying rollers 36b downstream of the back printing means 14 of the second conveying 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 kind of light beam is incident on a predetermined recording position X, and the photosensitive material A is scanned and exposed on the basis of the center while the center in the main scanning direction coincides with the center in the width direction of the photosensitive material A conveyed in the sub-scanning direction. A known light beam scanning device including a light source for each light beam, a light beam modulating unit, a light 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 and conveying means 42

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 above, 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.
