Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to an apparatus for making plates and printing on heat-sensitive stencil paper.

(Prior Art) Conventionally, a plate-making printing apparatus as shown in FIGS. 1 and 2 is known from Japanese Utility Model Publication No. 15814/1983. That is,
A sponge 2 is placed on the base 1, one end of the opening/closing plate 4 carrying the lamp house 8 is pivotally attached to one end of the base 1, and a transparent pressing plate 5 is attached to the opening of the lamp house 3. At the same time, by providing a base paper fixing frame 6 below the transparent pressing plate 5, the heat-sensitive stencil paper 8 is attached to the base paper fixing frame 6, and the original 7 is placed on the sponge 2, and the tip of the opening/closing plate 4 is pressed. The transparent pressing plate 5 on the bottom of the lamp house 3 presses the heat-sensitive stencil paper 8 onto the sponge 2 of the base 1, lights up the interior of the lamp house 3, heats it, and prints the letters and symbols of the manuscript 7 on the stencil sheet of the base paper 8. A similar perforation is obtained, and the heat-sensitive stencil paper 8 is made into a plate (plate making process). Next, the opening/closing plate 4 is opened, the stencil-made thermal stencil paper 8 is removed from the stencil fixing frame 6, ink is applied to the stencil paper 8, and then the thermal stencil paper 8 is attached to the stencil fixing frame 6 again (inking process). Then, place the printing material 9 instead of the original 7 on the sponge 2 and open/close the plate 4.
Heat-sensitive stencil paper 8 inked by pressing the tip
is pressed onto the printing material 9 (printing process), but in order to perform the inking process, the heat-sensitive stencil paper must be taken out each time, making the transition from the plate-making process to the printing process smooth. Furthermore, since the printing material 9 must be placed on the sponge 2 fixed to the base, it is not possible to freely print on any desired printing material like a stamp. Ta.

Therefore, as shown in FIGS. 3 and 4, a pressing body 10 is provided separately from the plate-making device, a sponge 11 is attached to the lower surface of the pressing body 10, and support frames 1 are attached on both sides of the sponge 11.
2 and 12 are fixed, both sides of the inked thermal stencil paper 13 are inserted, placed and pressed onto a desired printing material, and the thermal stencil paper 13 is uniformly pressed onto the printing material using the sponge 11 for printing. It is also known to do this (Utility Model Publication No. 54-154005), but the work efficiency is poor because the plate-made heat-sensitive stencil paper 13 must be attached to a separate presser 10, and a presser is prepared separately from the lamp house. The drawback was that it was expensive because it had to be used.

(Purpose) With this invention, once the thermal stencil paper is set, printing can be performed without removing the thermal stencil paper after plate making, and it can be freely printed on any substrate like a stamp, and the lamp house can also be used as a pressing body. It is an object of the present invention to provide a plate-making and printing device for heat-sensitive stencil paper which is easy to operate and has good operability at a low cost.

(Example) FIGS. 5 to 9 show an example of the present invention.
Reference numeral 20 denotes a lamp house with flash bulbs 22 attached to sockets 21 on both side walls, a reflector 23 fixed above it, a handle 24 formed at the top, two AA batteries stored inside, and a handle 24 on the bottom. A transparent pressing plate 25 is fitted and fixed flush with the plate, and engaging members 27 having snap fitting grooves 26 formed on both sides thereof are fixed. Note that the engaging member 27 may be formed integrally with the lamp house 20. 28 is a terminal plate that connects a plate making switch 40, which will be described later, and a battery. Reference numeral 29 denotes a base paper plate on which a receiving frame portion 31 of a size capable of fitting and holding the heat-sensitive stencil paper 30 is formed. 32 is a sponge 34 which is thicker than the hollow frame 33 inside the hollow frame 33.
This is a sponge plate in which the sponge 34 is fixed to the hollow frame 33 with the upper surface substantially flush and the lower surface of the sponge 34 protruding from the lower surface of the hollow frame 33 by a certain height. One end of the base paper plate 29 and one end of the sponge plate 32 are rotatably connected by a flexible connecting member 35. Base paper plate 29
Two cut grooves 36 are formed in the free end of the base paper plate 29, and both ends of a plate hook 37 are pivotally attached so as to be able to rotate within the cut grooves 36. A protrusion 38 is formed with a height lower than the height of the protrusion 38. Furthermore, two grooves 39 are formed at the free end of the sponge plate 32, with which the plate hook 37 can be engaged, and a plate-making switch 40 is attached to the lower surface of the sponge plate 32. There are plate hooks 3 on both sides of the bottom of the lamp house 20.
A hole 41 into which the protrusion 7 and the protrusion 38 can fit and protrude is formed.

Reference numeral 42 denotes a printing table, which has a recess 43 formed on its top surface for positioning the postcard, and a positioning protrusion 44 on one side.
is installed protrudingly.

The heat-sensitive stencil paper 30 referred to here includes a stencil sheet 45 consisting of elements to be perforated by heat and a support for holding the elements, an outer peripheral frame 46, and an ink-impermeable plate attached to one end of the outer peripheral frame 46. It consists of a transparent film 47 and is well known. Further, the connecting member 35 may have another structure, as long as the base paper plate can come into contact with the upper and lower surfaces of the sponge.

Next, the effect will be explained.

(Plate-making process) During plate-making, the sponge plate 3 is used as shown in Figure 6.
The original 50 is superimposed on the upper surface of the sponge 34 of No. 2,
Heat-sensitive stencil paper 3 is placed on the receiving frame 31 of the base paper plate 29.
0 is fitted and placed. Next, as shown in FIG. 7, the holding portion 24 of the lamp house 20 is held by hand, aligned on the base paper plate 29, and pressed into contact with the base paper plate 29. Since the sponge 34 protrudes from the lower surface of the sponge plate 32, the entire protrusion is compressed, and the heat-sensitive stencil paper 30 and the original 50 are evenly held between the transparent pressing plate 25 and the sponge 34, and in this state, plate making is performed. The switch 40 is pressed and the terminal plate 28 is energized, the flash valve 22 is turned on and heated, and the heat-sensitive stencil paper 30 is perforated in 50 original patterns and made into a plate. The plate-making pressure at this time is about 15 to 20 kg.

(Inking process) Next, as shown in FIG. 8, the lamp house 20 is removed, the transparent film 47 on the top surface of the thermal stencil paper 30 is turned over, inking is performed, and the transparent film 47 is removed again
polymerize.

(Printing process) Next, as shown in FIG. 9, the base paper plate 29 is rotated below the sponge plate 32 so as to come into contact with the lower surface of the protruding sponge 34, and the plate hook 37 is inserted into the groove 39 of the sponge plate 32. . Next, both sides of the sponge plate 32 are fixed by snap-fitting into the snap-fitting grooves 26 of the engaging members 27 on both sides of the lower surface of the lamp house 20. At this time, the heat-sensitive stencil paper 30 that has been made and inked is located at the bottom surface. Next, the grip part 2 of the lamp house 20
4, touch one end of the base paper plate 29 to the alignment protrusion 44 of the printing table 42, and press the alignment recess 4.
3, the sponge 34 is compressed by the transparent pressing plate 25, and is uniformly compressed until the protrusion 38 comes into contact with the lower surface of the sponge plate 32, and printing is performed. The printing pressure at this time is about 5 to 15 kg, which is lower than that during plate making.

Note that printing may be performed by contacting and pressing onto another printing material without using the printing table 42.

(Effects) In the present invention, a sponge that is thicker than the hollow frame is placed inside the hollow frame, and a holding member that holds one side of the outer circumferential frame of the thermal stencil paper can be rotatably brought into contact with the top and bottom surfaces of the sponge on one side of the hollow frame. A heat-sensitive stencil plate making/printing device comprising a base paper cassette attached as shown in FIG. Fitting grooves are provided at both ends of the bottom surface of the sponge plate in which both ends of the sponge plate can be fitted and fixed in a removable manner, so that the heat-sensitive stencil paper can be fitted and set in the receiving frame of the base paper plate, and the lamp house can be pressed from above. Once the plate is made, the lamp house can be removed and inking can be done as is.When printing, the base paper plate is rotated downward and the sponge plate is snapped onto the underside of the lamp house to form a single unit, just like a stamp. You can freely print on any substrate. In addition, the lamp house can be used as a pressing body without having to prepare a separate pressing body as in the past, so the plate-making and printing operations are easy to use and can be manufactured at low cost.
