DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photosensitive material storage magazine used for a photosensitive material processing apparatus such as a laser typesetting machine.

[0002]

2. Description of the Related Art Conventionally, in a film-shaped photosensitive material storage magazine used for, for example, a laser typesetting machine, a guide made of a thin stainless steel plate is provided on both sides of a photosensitive material opening 30 as shown in FIG. Plates 31 and 32 were fixed, and felts 33 and 34 were attached to guide plates 31 and 32, respectively. The film-shaped photosensitive material is passed through a slight gap formed between the felts 33 and 34, and the felts 33 and 34 hit both surfaces of the photosensitive material to provide light shielding.

[0003]

However, in such a structure, if the gap between both felts is reduced in order to improve the light-shielding property, it becomes difficult for the photosensitive material to enter. For example, in the case of a laser typesetting machine, there is a type in which the photosensitive material is once pulled out of the magazine and returned to the magazine again after the phototransfer process is completed. It does not matter much when the material is pulled out, but the edge of the photosensitive material rubs the surfaces of the felts 33 and 34 when trying to insert the material again, and the sliding of the photosensitive material becomes very poor. On the other hand, the photosensitive material is sent out from the typesetting machine main body at a uniform speed, and when the slip of the photosensitive material deteriorates, the photosensitive material is bent, which is very inconvenient. However, there is a contradictory problem that if the gap is widened so as to make it easy to enter, the light shielding property deteriorates. In addition, since the felts 33 and 34 and the guide plates 31 and 32 to which the felts 33 and 34 are fixed are long, if a deformation in processing or a variation in mounting occurs, a uniform gap cannot be maintained from one end to the other end in the longitudinal direction. In some cases, the photosensitive material may be inserted obliquely, or the light may be partially leaked.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a magazine for accommodating a photosensitive material capable of taking in and out a recording medium such as a sheet-like photosensitive material without deteriorating light-shielding properties. And

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is a magazine for storing a photosensitive material, which is mounted on a photosensitive material processing apparatus for performing a photosensitive process. An opening provided in the housing for inserting or ejecting a recording medium; a first plate member provided in the opening and extending a predetermined length in the interior direction of the housing; and an opening. A second plate member which is provided movably in opposition to the first plate member, abuts against the first plate member by an urging means to close the opening, and mounts the housing on the photosensitive material processing apparatus. An opening mechanism that, when mounted at a position, abuts a projection provided on the processing apparatus and separates the second plate member from the first plate member by a predetermined distance against the urging force of the urging means; It is provided with.

[0006]

With the above arrangement, when the housing is mounted at the mounting position of the photosensitive material processing apparatus, the opening mechanism comes into contact with the projection provided on the processing apparatus, and the opening mechanism opposes the urging force of the urging means. The second plate member is separated from the first plate member by a predetermined distance.

However, a thin sheet made of Teflon-based synthetic resin is laid between the holding plate 7 and the holding member 9 to reduce the frictional resistance between the holding plate 7 and the holding member 9. I have. Reference numeral 12 denotes an L-shaped spring engagement member having a root portion fixed to the holding member 9, and reference numeral 13 denotes one end of the spring engagement member 12.
(Spring means). The other end of the spring 13 is hooked on a spring locking portion 14 provided on the holding plate 7. The holding plate 7 is always attracted by the spring 13, and the guide plate 2 is urged in the direction of the guide plate 1. 15 and 16 are screws for fixing the spring locking member 12 to the holding member 9. Reference numeral 17 denotes a sliding sleeve attached to the bottom plate 5, and reference numeral 18 denotes a sliding sleeve.
7 is a slide pin that is slidably inserted into the slide pin 7. Reference numeral 19 denotes a protrusion 20 on the side for engaging with the slide pin 18.
Is a link member formed with a projection 21 at the lower portion for engaging with the holding plate 7. A shaft penetration hole 22 is provided above the end of the spring engaging member 12 opposite to the spring engaging portion. Reference numeral 23 denotes a shaft for holding a link member, which penetrates a hole 24 provided in the link member 19 and is inserted and fixed in a hole 22 provided in the spring locking member 12. The link member 19 is rotatably held above the holding plate 7 as shown in FIG.
Reference numeral 25 denotes an engagement pin provided at a portion located below the link member 19 at an end of the holding plate 7. As described above, the projection 20 of the link member 19 is engaged with the upper portion of the slide pin 18, and the projection 21 is engaged with the engagement pin 25 provided on the holding plate 7.

Next, the operation of the magazine having the above-described configuration in the embodiment will be described.

FIGS. 1 and 2 show a state in which the magazine is separated from the main body of the laser typesetting machine.
Is urged toward the guide plate 1 by the spring 13, and the felt 3 and the felt 4 are pressed against each other to be in a completely closed state.

On the side of the main body of the laser typesetting machine, as shown in FIG.
6 is provided with a pin 27 projecting therefrom so that when this magazine is mounted on the main body of the laser typesetting machine, the pin 27 hits the lower part of the slide pin 18 provided at the bottom of the magazine. FIGS. 4 and 5 show a state where the magazine is attached to the main body of the laser typesetting machine. Numeral 38 denotes an outer plate of the laser typesetting machine, numeral 39 denotes a magazine (housing), and numeral 40 denotes a handle. In the state where the magazine 39 is properly mounted, the slide pin 18 is pushed upward, the link member 19 is rotated, and the engaging pin 25 is pushed, so that the holding plate 7 and the guide plate 2 move in the direction of arrow A. I'm moving. Then, a gap 28 is formed between the felt 3 and the felt 4.

During the operation of the laser typesetting machine, the photosensitive material 29 which has been exposed to the laser beam and whose exposure has been completed is sent in the direction of arrow B by a feeder provided on the main body side, and is sent from the photosensitive material insertion port 6 into the magazine. Is inserted into. At this time, since the relatively wide gap 28 is formed between the felts 3 and 4, even if the photosensitive material 29 touches the felts 3 and 4, it does not receive much resistance.
