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 the Prior Art and Ideas) Conventionally, in such plate-making and printing presses, the stamper was fixed at a constant angle to the lever and was fixed in an unremovable manner. Therefore, when printing, the plate master attached to the stamper does not contact the paper to be printed in parallel, resulting in a difference in pressure force and uneven density. This method had the inconvenience of not being able to print on paper, handkerchiefs, shirts, and other fabrics.

The present invention aims to solve the above-mentioned problems by providing a plate-making printer in which the stamper always contacts the printing paper in a parallel position and can be easily removed from the lever and used freely. .

(Means for Solving the Problems) In order to achieve the above object, the plate-making printer of the present invention has a lever on the rear side of the upper surface of the main body that has a lamp house consisting of a reflector, a flash bulb, etc. In a plate-making/printing machine in which a stamper is pivotally mounted and abuts the upper surface of the main body on the inner surface of the lever, a support shaft is provided protruding from both lateral sides of the stamper, and a shaft support hole is provided on the inner surface of both lateral walls of the lever. is provided, and the support shaft of the stamper is rotatably fitted into the shaft support hole of the lever, so that the stamper can swing freely relative to the lever, so that the stamper assumes an equilibrium state parallel to the top surface of the main body. None, and guide grooves are provided on the inner surfaces of both side walls of the lever to guide the support shaft of the stamper from the shaft support hole of the lever so that it can escape to the outside, thereby making it possible to remove the stamper from the lever. The gist is that a knob protrusion for use alone is provided on the back surface.

(Embodiment and operation) The figure shows an embodiment of the plate-making and printing machine of the present invention, and the operation and operation of the embodiment will be explained in detail below based on the drawing.

The plate-making printer is mainly composed of a main body 2 having a lamp house 1 and a lever 4 having a stamper 3.

The support shaft 17 is inserted through the support shafts 6a and 16a', so that the support shaft 17 is pivotally connected to the main body 2 so as to be able to rise and fall freely. Pivot holes 4b and 4b' are formed on the inner surfaces of both side walls of the lever 4, and guide grooves 4c and 4c' are bent from the side wall edges and communicate with the shaft support holes 4b and 4b'. The support shaft 18 of the stamper 3 passes through the grooves 4c and 4c'.
18' can be inserted into or removed from the shaft support holes 4b, 4b'. The stamper 3 includes a substrate 19, an elastic pad 20 made of urethane, a holder frame 21, and support shafts 18 and 1.
The base plate 19 has a knob protrusion 19a at the center of its back surface, arcuate protrusions 19b and 19b' at the center of both lateral sides, and a support shaft insertion hole 19c on its outer wall surface. 19c', the elastic panel 20 is superimposed and bonded to the ventral surface of the substrate 19, and the holder frame 21 has an abutment plate section 21a that is open at the center and superimposed on the back surface of the substrate 19. The protrusion 19 of the substrate 19 has through holes 21b and 21b' protruding from the center position of both lateral edges.
Support shaft fitting holes 19c, 19 are provided on the outer wall surface of b, 19b'.
The protruding pieces 21c, 21c' and the abutting plate part 2 are brought into contact with c' and the through holes 21b, 21b' are aligned.
Piece portion 21 protruding from both lateral sides and rear side of 1a
Folding pieces 21d, 21d', 21d'' projecting a required width in the direction opposite to c and 21c', and locking elements that are bent inward at the tips of the folded pieces and lock the side edges of the plate master 12 during printing. It has stopper parts 21e, 21e', 21e'',
The support shafts 18, 18' are inserted into the support shaft insertion holes 19c,
One end is inserted into 19c' through the through holes 21b, 21b' of the holder frame 21, and the other end is removably fitted into the shaft support holes 4b, 4b' of the lever 4 as described above in a protruding state. Therefore, the stamper 3 has its support shaft 1
8 and 18', the central part thereof is suspended rotatably relative to the lever 4, and when the lever 4 is raised or lowered, it swings and tilts by a certain angle relative 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, the stamper 3 can be removed from the lever 4. It is also possible to print on fabrics such as paper, handkerchiefs, and shirts.

(Effects of the invention) The invention is as described above. First, a support shaft is provided protruding from both lateral sides of the stamper, and a shaft support hole is provided on the inner surface of both lateral walls of the lever, so that the support shaft of the stamper can be fixed. The stamper is rotatably fitted into the shaft support hole of the lever so that it can swing freely relative to the lever, so that the stamper is in an equilibrium state parallel to the top surface of the main body, so the plate attached to the stamper is The master comes in parallel contact with the printing paper set on the top of the main body, resulting in uniform and beautiful printing, and also allows the stamper's support shaft to be guided through the lever's shaft support hole to escape to the outside. By providing guide grooves on the inner surfaces of both side walls of the lever, the stamper can be removed from the lever, and a knob protrusion is provided on the back of the stamper for use alone, so it is not large enough to be set on the main body. It is extremely convenient to be able to freely print on paper, fabric, etc.
