Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a plate-making and printing device that can easily perform plate-making and printing with one unit.

(Problems to be solved by conventional techniques and ideas) Conventionally, in this type of plate-making printer, the stamper is integrally fixed to the lever at an angle and cannot be removed, so when printing, the stamper The plate master attached to the main body does not contact the printing paper in parallel, which causes a difference in the pressure contact force, resulting in uneven density, or when printing paper, handkerchiefs, or shirts that are too large to be set on the top of the main unit. There was the inconvenience of not being able to print freely on fabrics such as.

In addition, it is difficult to set the plate master in the correct position relative to the lamp house during plate making, or to set the paper to be printed in the correct position on the top surface of the main body with respect to the plate master set in the stamper during printing. There were also inconveniences in that printing paper, especially paper stacked to print on a large number of sheets, was easily misaligned, making multicolor printing difficult.

Furthermore, when a plate master coated with ink is set in the holder frame of the stamper and printing is carried out by pressing the plate master against the paper to be printed, the paper to be printed may adhere to the plate master due to the adsorption of the ink. This also had the disadvantage that the work of peeling it off was troublesome and did not improve work efficiency.

The purpose of the present invention is to provide a plate-making/printing device that comprehensively solves these problems.

(Means for Solving the Problems) In order to achieve its purpose, the present invention has a lever that is pivotally mounted on the rear side of the upper surface of the main body having a lamp house consisting of a reflector, a flash bulb, etc. In a plate-making printer in which a stamper is installed in contact with the top surface of the main body, a shaft is provided protruding from both lateral sides of the stamper, and a shaft support hole into which the shaft is fitted into the inner surface of both lateral walls of the lever. The shaft support hole is provided with a guide groove through which the support shaft can communicate from the edge of the side wall, and the stamper is rotatably attached to the lever by fitting the support shaft into the shaft support hole, and the stamper is rotatably attached to the lever. A holder in which a concave groove is formed around the transparent plate covered by the top of the upper lamp house, and an elastic pad is loaded into the concave groove to provide a setting part for positioning the plate master and printing paper. The stamper is placed on the upper surface of the elastic pad and fitted into the concave groove so as to be able to move up and down.Furthermore, at one end of the holder frame for the plate master set that is integrated into the stamper, there is a slight gap between it and the set plate master. The present invention provides a plate-making/printing machine characterized by integrally forming a separator that slightly protrudes from the inner surface of a plate master with a gap.

8 and 18', the central part thereof is suspended rotatably from the lever 4, and when the lever 4 is raised or lowered, it swings and tilts by a certain angle with respect to the lever 4.
Immediately before coming into contact with the printing paper 22, the front and rear balance is maintained, and the paper is in a horizontal state, so that the printing paper 22 comes into contact with the printing paper 22 in parallel.

As shown in Fig. 1, the plate-making work using the plate-making printer is as follows: First, a thermal plate-making master 12 is set on the upper surface of the transparent plate 8 on the upper surface of the main body in the correct position with the holder 11 facing the lamp house 1, and a manuscript is placed on top of the thermal plate-making master 12. The stamper 3 is placed face down on the upper surface of the main body by rotating the lever 4, and the elastic pad 20 of the stamper 3 is pressed onto the original. At this time, a push button 23 provided on the front side of the inner surface of the lever 4
contacts the switch 15 on the top of the main body and turns it on, causing the flash valve 7 to emit light and plate making to be performed. In addition, as shown in FIG. 2, the printing operation is carried out by first applying ink to the plate master 12 that has been made, setting it in the holder frame 21 of the lever 4, and placing it on the transparent plate 8 on the top of the main body at the center opening of the holder 11. The printing paper 22 such as a postcard is inserted into the plate 11b and placed in a positioned state, and the lever 4 is turned face down to release the master plate 12.
This is done by pressing the paper 22 to be printed.
When the lever 4 is raised, the printing paper 22 may be attracted to the plate master 12 by ink, as shown in FIG. 3, and this removal work is troublesome. At one end of the locking piece 21e, there is a separator 24 that is interposed between the plate master 12 and the paper to be printed 22 and slightly lifts the edge of the paper to be printed 22 to facilitate the peeling operation. It is integrally formed at a slight angle to the As mentioned above, the holder 11 attached to the top surface of the main body is vertically movable,
This makes it possible to cope with changes in thickness when printing on a large number of sheets of paper 22 to be printed.

In the plate-making printer of the present invention, as mentioned above, the stamper 3 can be removed from the lever 4, so if the printing material is too large to be placed on the top surface of the main body by grasping the knob protrusion 19a of the removed stamper 3, it is possible to remove the stamper 3 from the lever 4. It is also possible to print on fabrics such as paper, handkerchiefs, and shirts.

(Effects of the invention) The present invention has the above-described structure and function. First, the stamper always comes into contact with the top surface of the main body in parallel, resulting in a beautiful printing result. Also, the size of the stamper makes it impossible to remove it from the main body and set it on the main body. This has the effect of allowing you to freely print on paper, fabric, etc. In addition, since the plate master and printing paper are set in the correct position by the holder, there is no unevenness in plate making, and even when many sheets of printing paper are stacked, there is no misalignment, allowing multicolor printing. It also has the effect of allowing you to easily and accurately do the following. Furthermore, the separator provided in the holder frame of the stamper makes it easier to peel off the printing paper attached to the plate master, which has the effect of improving work efficiency.
