Abstract

PURPOSE:To prevent a transparent plate and a light shield curtain from being in trouble and a gap from being formed between the both by supporting the end part of the reinforcing belt body at the head end of each light shield curtain by a mechanism which is fixed to the guide body for the reinforcing belt body at right angles to the transparent plate surface and drives constant-distance reciprocation, and fitting an elastic material on the reverse surface of the reinforcing body. CONSTITUTION:On the guide body 6 which is driven on a feed screw 5, each air cylinder 10 is fixed upright opposite the transparent plate 2, and both end parts of the reinforcing body 4 atop each light shield screen 1 are fixed to the head end of the rod 100 of the air cylinder 10. Then the stroke of each air cylinder 10 is so set that when the rod 100 is extended after the position of the light shield curtain 1 is set, the elastic material 11 fixed on the reverse surface of the reinforcing belt body 4 strikes on the surface of the transparent plate 2 and when the rod 100 is contracted, light shield curtains 1a and 1b and transparent plate 2, and the light shield curtains 1a and 1b and light shield curtains 1c and 1d are isolated at necessary intervals. Consequently, troubles between the light shield curtains and transparent plate, and the light shield curtains themselves is eliminated and the gap formed between the light shield curtains and transparent plate is eliminated.

《Conventional technology and problems》 . In the process of plate making, the image on the original film is printed and transferred onto the surface of the plate material.This process involves bringing the original film and the plate material into close contact with each other, and then vacuuming the gap between the two. Complete ffi by eliminating using pressure
It is then exposed to light. In this exposure process, the area other than the image area of the original film that is positioned and fixed at the center of the transparent plate of the original film holder (the margin around the image area of the original film and the transparent plate around it) is shielded from light. Therefore, an automatic masking device is used as a means for forming this light-shielding area.

Easily scratched. Furthermore, since the upper and lower light-shielding curtains (la) (1b) and the left and right light-shielding curtains (1c) (1d) operate while rubbing against each other, work problems may occur due to the light-shielding curtains (1) getting caught in each other. Constant anxiety (in this case,
There is a risk of causing damage due to light shielding 1tI(1))
.. [Problem ■1] As shown in Figure 7, between the left and right light-shielding curtains (LE) (LD) arranged on the upper side (front side) and the transparent plate (2> ) (lb), it is inevitable that a gap (S) corresponding to the thickness of the reinforcing band (4) will occur.

However, in this automatic masking device, since the light-shielding area is formed through the transparent plate (2), it is required to minimize the elements through which the exposure light goes around (for this reason, in practice, it is necessary to Due to the thickness of board (2), we are pursuing thinness to the limit).

This gap (S) is an element that completely contradicts the above request,
This must be solved quickly, but until now this point has not been resolved, and in the end, in practice, it is necessary to widen the distance between the light source and the light-transmitting plate (2) (i.e., the original image holder). In reality, the only way to deal with the situation is to provide exposure by placing the light source as far away from the camera as possible, or by considering the printing interval for multiple images.

<<Means for Solving the Problems>> In the present invention: An original image of a honey-glazed seashore in which a desired light-shielding area is formed into a shape by extending light-shielding curtains onto the light-transmitting plate from the top, bottom, left and right of the light-transmitting plate, respectively. In an automatic mask device in a holder, a pair of opposing light-shielding curtains arranged on the transparent plate side are separated from the light-transmitting plate by a required distance, and a pair of opposing light-shielding curtains arranged on the front side are further separated from the above-mentioned pair of light-shielding curtains. In addition to placing and supporting the required distance, the end of the reinforcing band at the tip of each light-shielding curtain is
8! It is perpendicular to the transparent plate surface and is fixed to the dielectric of it (reinforcement band) and driven back and forth a certain distance! The above-mentioned problem can be solved by attaching an elastic material with resilience to the lower surface of the reinforcing band.
■We tried to solve the problem all at once.

In addition, in Fig. 2, the reinforcing band (
4) is supported at only one end by an air cylinder (6) fixed to an inductor (6) that moves on a feed screw (5) that is directly driven by a precision drive motor (7). As shown in the figure, it is rotatably installed on the opposite side of the feed screw (5) shown in the figure, which is directly driven by a precision m-shift motor (7), and is synchronized with the same feed screw (5). Because the drive belt is stretched across the drive belt, the same feed screw (
It goes without saying that the other end is supported by an air cylinder fixed to an inductor that moves on a feed screw that is rotationally driven in synchronization with 5). The illustration of some of the members shown in the figure is omitted in order to avoid complication in the illustration. Manoko, reinforcing band (4
) can be made as thick and strong as possible, so by extending the rod of the air cylinder (10), a thick elastic material (11) attached to the bottom surface of the air cylinder (10) can be used. It can be pressed strongly enough against the surface of the light-transmitting plate (2), and the intended purpose (eliminating the gap) can be achieved.

《Effects of the Invention》 ■ Each light-shielding curtain is arranged and supported at a required interval so that they do not touch each other and the light-shielding curtain on the light-transmitting plate side does not touch the light-transmitting plate. During operation, the pair of light-shielding curtains placed on the transparent plate side and the pair of light-shielding curtains placed on the front side rub against each other, and the pair of light-shielding curtains placed on the transparent plate side touch the surface of the transparent plate. This eliminates any rubbing of the light-shielding curtains, prolongs the life of each (the light-shielding curtain and the light-transmitting plate), and at the same time brings about the special effect of eliminating work troubles caused by the light-shielding curtains catching on each other.

■ As mentioned above, each light-shielding curtain is placed and supported at the required intervals, and at the same time, the reinforcing band at the tip of each light-shielding curtain is supported by a mechanism that reciprocates a certain distance at right angles to the transparent plate. By doing this, we were able to attach a thick elastic material with sufficient elasticity to the lower surface of the reinforcing band at the tip of the blackout curtain, especially on the front side. Therefore, once the position of the blackout curtain was set, this By pressing the reinforcing band perpendicularly to the transparent plate using a mechanism that reciprocates a certain distance, the elastic material is pressed against the transparent plate surface, creating a gap between the light-shielding curtain on the front side and the transparent plate. It also has the special effect of eliminating the problem.
