Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for developing a photosensitive material, which is developed by peeling off the cover base of the photosensitive material, which is laminated to a support via a photosensitive layer.

It consists of a support (for example, an aluminum plate, etc.), a photocurable substance-containing layer as a photosensitive layer (hereinafter referred to as photosensitive layer), and a light-transmitting cover base (for example, polyethylene terephthalate, etc.), and the exposed portion of the photosensitive layer is A photosensitive material that hardens and adheres to the support, with unexposed portions adhering to the cover base, is developed as a resist image on the support by peeling off the cover base.

Conventionally, developing devices for such photosensitive materials include:
For example, as disclosed in Japanese Patent Application Laid-Open No. 51-9451, there is a method in which an adhesive tape is attached to the surface of a cover base and developed by rolling it up and peeling off the cover base. In addition to requiring materials, it requires an adhesive tape supply mechanism, which increases the cost of the device itself and running costs, and there is also concern about problems if the adhesive strength of the adhesive tape and cover base is insufficient. Ta.

Another conventional device is one that attaches the cover base to a roller with suction holes on its circumferential surface and peels it off to develop an image, but this requires a vacuum pump and air control mechanism, making the device large. This meant that the costs were increasing.

It is an object of the present invention to provide a developing device that eliminates the drawbacks of the conventional device described above and can reliably peel off a cover base with a simple mechanism without requiring extra materials such as adhesive tape.

In order to achieve the above object, the present invention includes a roller having a large number of fine protrusions on its surface, which rotates in the opposite direction to the photosensitive material transfer direction on the cover base side along the photosensitive material transfer path. It is characterized by

The present invention will be described in detail below based on its embodiments. FIG. 1 is a side view of an integrated processing apparatus that is an embodiment of the present invention, and the developing device 1 includes a brush roller 1 as a main part.
0. Insertion table 2 with operation table 11 and heating table 12 as main parts
0, a recovery device 30 including a winding tube 21 and a drive roller 22 as main parts, a gum liquid tank, [-31 and an application roller 3
The main parts are a gum coater 40 having 2 and 33 as main parts, a roller conveyor 41, and a post-exposure drying device 50 having an ultraviolet light source 42 as main parts.

The insertion table 20 serves to supply the photosensitive material to the developing device and to heat the photosensitive material to the optimum temperature for development. The collecting device 30 functions to wind up the cover base peeled off by the developing device 10 in order to dispose of it. The gum coater 40 functions to peel off the cover base in the developing device 10 and apply a protective layer to the image surface of the support having the hardened photosensitive layer. The post-exposure drying device 50 serves to further cure and stabilize the cured photosensitive layer forming an image on the support with ultraviolet rays, and also to dry the gum coating layer as a protective layer. The developing device 10 includes a brush roller 1, a conveyance roller 2,
2A, the brush roller 1 is a nylon flocked roller whose surface is a so-called skewer-shaped roller with the flocked hair partially removed, and a comb-shaped peeling member 4 that fits into the concave part of the brush roller 1 is a nylon flocked roller. is provided. Further, the conveyance roller 2A is also a so-called skewer-shaped roller, and a comb-shaped peeling member 4 that fits into the concave portion thereof is provided. In this embodiment, the photosensitive material inserted from the operation console 11 with the cover base facing downward is placed on the heating table 12 on the top surface of the hot chamber 13 to which hot air is supplied, and the hot chamber 13 and the hot air blowing nozzle 14 are used to optimize the development. heated to temperature.

The photosensitive material whose cover base is easily peeled off due to heating is sent to the developing device 10 by the conveying rollers 2 and 2A, and is recovered by being scratched by the brush roller 1 rotating in the opposite direction. The tip of the base is peeled off from the support. The photosensitive material from which the cover base has been peeled off is further linearly transferred to a gum coater 40, and the peeled cover base is sent downward along the brush roller 1. The cover base attached to the brush roller 1 is peeled off from the brush roller 1 by a comb-shaped peeling member 4 fitted into a recessed portion of the brush roller 1, and sent to a collecting device 30 below and wound up. The photosensitive material from which the cover base has been peeled off is coated with a cam liquid to form a protective layer by a gum coater 40, and then the image area is stabilized and the gum liquid is dried by a post-exposure drying device. All burials are completed.

FIG. 2 is a side view showing another embodiment of the developing device, which is characterized in that a scratching member 5 is provided between the conveyance roller 2B and the brush roller 1.

The scratching member 5 is made of a material such as a file having fine, sharp irregularities on its surface, and its action is to scratch the tip of the photosensitive material with its sharp surface to create a "tight spot" for peeling off the cover base. To ensure that the cover base is peeled off by a brush roller 1 easily and reliably. Therefore, when the scratching member 5 has finished creating a "tight spot" for peeling off the cover base at the leading end of the photosensitive material, the scratching member 5 is removed in order to prevent further damage to the photosensitive material. It is desirable to allow the photosensitive material to escape to the lower side of the transfer path.For this purpose, a limit switch 6 is provided to detect when the leading end of the photosensitive material has passed the scratching member, and a signal from the limit switch 6 causes the scratching member to move. All you have to do is change the position of 5. Third
The figure is a side view showing still another embodiment of the developing device, in which a second brush roller 7 is provided between the conveyance roller 2B and the brush roller 1 for making the above-mentioned "tightening" of peeling off the cover base. It is characterized by:

This brush roller 7 is a nylon brush roller with short bristles and is configured to rotate in the opposite direction to the direction in which the photosensitive material is transported. In this case, as in the case of the above-mentioned scratching member 5, when it is detected that the tip of the photosensitive material has passed the brush roller 7, the brush roller 7 can be released to the lower side of the photosensitive material transfer path. It's good to leave it there. Further, as shown in FIG. 4, if the brush roller 7 is set at a certain angle with respect to the transfer direction within the transfer plane of the photosensitive material, the shock when the photosensitive material hits the brush roller 7 is softened, and the cover base is Since the photosensitive material is peeled off sequentially starting from the corners, an excellent effect is achieved in that the peeling can be performed extremely smoothly. When cutting a photosensitive material, the cover base that is stretched during cutting often sticks to the cut surface of the support in a smeared manner. In order to do this, it is extremely important to mechanically cut or peel off the end of the cover base that is attached to the cut surface of the support, like the above-mentioned scratching member 5 and brush roller 7. have

As explained above, according to the present invention, the cover base can be reliably peeled off from the support and development can be performed using an extremely simple mechanism without requiring extra materials such as adhesive tape.

In addition, as in the embodiment shown as an integrated processing device, by combining it with a heating table that brings the temperature to the optimum temperature for developing the photosensitive material, it is possible to make the work easier and to perform development without mistakes. The cover base can also be processed continuously without taking up much space by combining the cover base with a winding type recovery device that utilizes the adhesiveness of the photosensitive layer remaining on the cover base. Furthermore, post-treatment of the support bearing the developed image can be carried out in a consistent manner by using the above-mentioned combination of the gum coater and the drying device which also serves as post-exposure.
