1 is a side sectional view of an embodiment of the present invention, comprising a printing plate mounting plate 2 having a vacuum suction port 3 on a support table 1;
A printing plate fixing pin 4 is attached and fixed to the operator's side end. At the upper edge and the lower edge of the mounting plate 2,
A movable pin 5 that can be positioned and fixed is provided along each edge. A wind-up light-shielding sheet 6 is provided so as to be superimposed on the mounting plate 2. The light-shielding sheet 6 is formed by shifting two rows of light-shielding regions and light-transmitting regions which are alternately formed using a transparent film as a supporting base material to form a pine pattern. The light-shielding sheet 6 can be wound or unwound by, for example, 1/2 pitch of one unit light-shielding pattern by rolls 7 and 8 whose both ends are driven by a micromotor. Reference numerals 9 and 10 are freely rotating guide rolls. Drive rolls 7, 8 and guide rolls 9, 10
Is supported by the upper frame 11. The frame 11 is supported on the outer frame 12 of the support base 1 via a hinge 13 so as to be openable and closable, while being able to be in close contact with the frame 12 via a sealing seal. The frame 11 includes a light shielding sheet 6 and a transparent plate.
14 is installed. Reference numeral 15 denotes an air outlet for sucking air from the suction port 3. The movable pin 5 is a movable member
The movable member 16 is driven by, for example, an endless belt or an air cylinder, and can be moved and stopped at a predetermined position. In another embodiment of the present invention, without attaching the transparent plate 14 to the frame 11,
The air-impermeable light-shielding sheet 6 is directly pressed against the outer frame 12 of the support base 1 by the upper frame body 11 to seal the periphery of the light-shielding sheet 6, and vacuum suction is performed through the suction port 3. By vacuum-suctioning the printing plate loading portion 17 such as a printing plate and a halftone positive film, printing can be performed by bringing the printing plate and the printing plate into close contact with each other.

As shown in the figure, two types of screen positive films b and c are positioned and fixed diagonally using the screen positive film fixing pins 5. Then, the transparent plate 14 supported by the upper frame body 11 is closed, and the light-shielding sheet 6 is run by rotating the drive roll 7 or 8,
The setting is made so that the translucent area is located on the images of the halftone positive films b and c, and the light-shielding area 18 is located at the part without the halftone positive film, and the operation is stopped. Then, the plate is exposed to ultraviolet light from above the upper frame 11 of the printing machine, and printing in one diagonal direction of the first color PS plate a1 is completed. Next, the PS plate a2 of the second color is fitted to the pin 4 for fixing, the predetermined mesh positive films b2 and c2 are positioned at the same pin position on the plate a2 and brought into close contact with each other by vacuum suction. After the exposure, the printing in one diagonal direction of the PS plate a2 for the second color is completed. In this way, the Nth PS plate an is sequentially printed using the halftone positive films bn and cn, and printing in one diagonal direction is completed. next,
FIG. 4, the light-shielding sheet 6 is stopped by moving the light-shielding sheet 6 by 1/2 pitch, and the original plate fixing pin 5 is moved in the other diagonal direction so that each of the pins 5 faces the light-transmitting area of the light-shielding sheet 6. After stopping at a predetermined position, with the upper frame 11 opened, the PS plate a1 of the first color is fitted to the fixing pins 4 and positioned, and then another mesh positive film d1, e1 is placed on the plate a1. Then, after fitting to the film fixing pins 5 and positioning, vacuum suction and close contact, exposure is performed in the same manner as described above to complete the four-side printing of the first color PS plate a1. Thereafter, the same operation is performed, and the N-color PS plate an is printed on four sides. FIG. 5 is a plan view of an N-color PS plate subjected to four-side printing. The driving of the movable member for moving the original plate fixing pin 5 to a predetermined position in the present invention is performed by inputting a command content such as a moving amount and a moving direction, and then setting a pulse number of the motor rotation speed using a step micromotor or the like. Position control, and sequence control by a microprocessor.
