However, in the plate making apparatus, normally, the character to be printed is input by the input means and confirmed by the liquid crystal display or the like. However, the display resolution of the liquid crystal display and the thermal perforation by the thermal head are used. Since the perforation resolution is markedly different, the display resolution of the liquid crystal display is coarser, and even if you try to confirm how the stamp image is formed after entering the data with the keyboard, the stamp on the liquid crystal display shows a rough stamp. Only the degree of image placement is known, and in the end, the confirmation is done by trial pressing or judging by looking at the stamp surface.If the formed image is not satisfactory, the stencil printing plate Had the drawback of having to throw away.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view of the stamp device 12 of this embodiment. The stamp device 12 is a keyboard 1 for inputting characters or functions on the upper surface of the cover 14.
6, a liquid crystal display 18 for displaying characters and the like according to an input from the keyboard 16, an on / off key 20 for instructing to turn on or off a power source, and a plate making key 22 for instructing plate making. Cover 1
A stamp groove 26 for arranging the stamp member 140 is provided on the upper surface of the rear part of the No. 4, and a discharge guide tray 30 for discharging the thermal recording sheet after printing is provided on the right side of the stamp groove 26. The plate making mechanism is connected through a discharge port 28. The side surface of the cover 14 is provided with an insertion groove 24 for mounting a stencil printing plate 120, which will be described later, during plate making.

The heat-sensitive recording sheet 52 is made by cutting heat-sensitive paper, which is conventionally used for printing with a general thermal head, in accordance with the size of the rear portion of the plate making machine of the present apparatus.

Next, FIG. 2 shows a cross-sectional view of the plate-making mechanism portion of the stamp device 12, which is a cross-sectional view taken along the line EE of FIG. In the figure, in the vicinity of the insertion groove 24, the stencil printing plate 120 or the heat-sensitive recording sheet 52 inserted from the insertion groove 24.
An insertion detection switch 50 for detecting is provided. The thermal head 32 is attached to a support member 36 integrated with a heat dissipation plate, and the support member 36 is rotatable by a drive mechanism (not shown) as shown by a dotted line in the figure. The thermal recording sheet discrimination switch 48 is turned on at the position where the thermal head 32 is shown by a solid line, and is turned off at the dotted line position.

Further, a push-up roller 38 is attached to the supporting member 36 by a roller supporting arm 40, and the supporting point of the roller supporting arm 40 is fixed to the supporting member 36.
A spring force (not shown) works to constantly pull up the push-up roller 38. The platen 34 sandwiches the stencil printing plate 120 or the thermal recording sheet 52 with the thermal head 32, and rotates in the direction of arrow C to send out. Further, the thermal recording sheet feeding roller 42 also rotates in the same direction as the platen to feed the thermal recording sheet 52 to the discharge port 28. Similarly, the stencil printing plate feed roller 44 also rotates in the same direction as the platen 34 to feed the stencil printing plate 120 below the stamp member 140 after plate making. Further, the feed rollers 46a and 46b have a function of rotating in a direction opposite to the rotation direction of the platen 34 and feeding out the stencil printing plate 120.

Next, the stencil printing plate 120 of the present embodiment.
Will be described with reference to FIG. Master plate 120 for stencil printing
Is roughly divided into a heat-sensitive stencil sheet 122, a separator 124, a non-woven fabric 126 impregnated with ink, a frame 128 having an opening 127 surrounding the non-woven fabric 126, and an ink impermeable base material. Film 1
It is composed of 30 and.

As shown in FIG. 10, the heat-sensitive stencil sheet 122 comprises a thermoplastic film 150, an adhesive layer 152, and a porous support 154. The thermoplastic film 150 of this embodiment is a polyethylene terephthalate film (PET film) having a thickness of 2 μ, but other films such as polypropylene and vinylidene chloride-vinyl chloride copolymer can be used. The thickness of the PET film is preferably 1 μm to 4 μm. If the thickness is less than 1 μm, the manufacturing cost is high and the strength is weak, which is not practical. Further, if the thickness is 4 μm or more, a general thermal head having a rating of about 50 mJ / mm ² is too thick to punch.

The porous support 154 is, for example, Manila hemp,
Porous thin papers, which are mainly made of natural fibers such as groove, Mitsumata, synthetic fibers such as polyethylene terephthalate, polyvinyl alcohol and polyacrylonitrile, and semi-synthetic fibers such as rayon, are used.

In the frame 128, an opening 127 corresponding to the size of the nonwoven fabric 126 and a square hole 129 for extracting the separator 124 are formed in the central portion. An adhesive layer 132 for adhering the heat-sensitive stencil sheet 122 is applied to the upper surface of the frame 128 on the four sides. Non-woven fabric 1
Since the ink impregnated in 26 is an oil-based ink,
As the material of the frame body 128, vinyl chloride, polypropylene, polyethylene, polyacetal, polyethylene terephthalate or the like that is not attacked by the oil-based ink is used.

The non-woven fabric 126 is impregnated with the oil-based ink in a saturated state, and the impregnated ink oozes out when pressure is applied to the non-woven fabric 126. Non-woven fabric 12
6 uses synthetic fibers such as polyethylene, polypropylene and polyethylene terephthalate. Non-woven fabric 12
The thickness of 6 is preferably set to be ½ or more and 3 times or less of the thickness of the frame 128. If the thickness of the non-woven fabric 126 is too thin, the heat-sensitive stencil sheet 122 will enter the inside of the frame 128 during plate making, and will not contact the thermal head 32, making it impossible to punch. If the thickness of the non-woven fabric 126 is too thick, the non-woven fabric 12 is pressed by the thermal head 32.
6 is compressed and pops out of the frame 128. In such a state, the stencil printing plate 120 cannot be transported by the frame 128 during plate making. Therefore, variations in the thickness of the non-woven fabric 126 cause unevenness in the transporting and feeding pitch of the stencil printing plate 120, and skew feeding. Then, problems such as transporting occur. At the time of plate making, it is preferable that the nonwoven fabric 126 is compressed by the pressing force of the thermal head 32 so as to have the same thickness as the frame 128.

The separator 124 is a heat-sensitive stencil sheet 12.
2 and the non-woven fabric 126, the end of the separator 124 is passed through a square hole 129 provided in the frame 128, and is passed between the frame 128 and the film 130 to perform stencil printing. It is projected to the outside of the original plate 120.

This will be specifically described with reference to FIG. 11. Inside the hatched portion of the frame 128, the nonwoven fabric 126 is the separator 1.
The area covered by 24. Separator 124
As the release paper, a release paper obtained by subjecting high-quality paper or glassine paper to silicon treatment, or a resin film of polyethylene terephthalate, tetrafluoroethylene (for example, Teflon under the trade name), or the like is used.

As the required characteristics, those having poor wettability with the oil-based ink are preferable, and specifically, the wetting angle is preferably 45 degrees or more. When using release paper or the like, it is preferable to apply silicon processing not only to the contact surface with the nonwoven fabric 126 but also to the entire surface. This is because when the wettability is good or the silicon is processed on only one side, the ink spreads to the side of the heat-sensitive stencil sheet 122, and there is a risk that the ink will ooze out from the perforated portion during perforation.

Film 13 which is an ink impermeable substrate
In No. 0, the adhesive layer 134 is applied to the upper surface (hatched portion in FIG. 11) and is adhered to the frame 128 and the nonwoven fabric 126. As the film 130, a resin film made of vinyl chloride, polypropylene, polyethylene, polyethylene terephthalate, or the like that is not affected by the oil-based ink is used.

Next, the control system of the stamp device 12 will be described with reference to the block diagram shown in FIG.

It is connected to the G-ROM 84 and the output interface 80.

The ROM 64 includes a program memory 66 storing a program for controlling the overall operation of the stamp device 12, and a dictionary memory 68 used for kana / kanji conversion or the like. The RAM 70 includes an input buffer 72 that stores data input from the keyboard 16, an edit buffer 74 that stores data for printing the stencil printing plate 120 by thermal punching or printing on the thermal recording sheet 52, and a shift register 76. It has the necessary counters and registers.

The plate-making printing CG-ROM 82 generates a dot pattern based on the code data of the input character, and the display CG-ROM 84 displays a display dot pattern to be displayed on the liquid crystal display 18. It occurs.

A head drive circuit 90, a motor drive circuit 92, and a display drive circuit 96 are connected to the output interface 80, and the thermal head 3 is connected to each of them.
2. A motor 94 that also serves as a carrier, a head pressing member, and a carrier, and a liquid crystal display 18 are connected.

Next, the flow of the main program in the control method of the stamp device 12 will be described with reference to FIG. First, after the start, an initial state around the CPU 66 is set (step S101, hereinafter simply referred to as S101, and the same applies to other steps), a key scan of the keyboard 16 (S102) is performed, and it is input that there is an input. It is determined whether the key is a character (S103). If it is a character, data input processing is performed (S104), and the input character is displayed on the liquid crystal display 18 (S105), and key scan (S102).
Return to. If it is determined that the character is not a character in S103, it is determined whether or not the plate making key 22 is pressed (S106). If the plate-making key 22 is not pressed, another process (S107) is performed to perform a key scan (S10).
Return to 2). If the plate making key 22 is pressed, it is determined whether the insertion detection switch 50 is turned on (S108). If it is not turned on, a display is displayed on the liquid crystal display 18 so that the stencil printing plate 120 or the thermal recording sheet 52 is mounted (S109), and S1
Return to 02.

If the insertion detection switch 50 is on,
The motor is driven so as to push up the thermal head 32 and sandwich the base paper (S110). Next, it is determined whether or not the thermal recording sheet discrimination switch 48 is turned on (S111). Thermal recording sheet 52 if turned on
Is determined to have been inserted, the process proceeds to S118. On the contrary, if it is off, it is determined that the stencil printing plate 120 is inserted, and the process proceeds to S112.

The mirror image data for punching is edited (S11
2) Set the number of plate making lines (S113). next,
The stencil printing plate 120 is punched for one line by driving the thermal head 32 in accordance with the one-step feed of the motor 94 and the dot pattern edited for plate making (S114). The number of plate making lines is stored (S115).

Next, it is determined whether the number of plate making lines is 0 (S116). If it is not 0, the process returns to S114,
This process is repeated until the number of plate making lines becomes zero.

When the number of plate making lines becomes 0, the punching of the stencil printing plate 120 is completed. Then, the stencil printing plate 120 is sent out immediately below the stamp member 140 (S117), and the process returns to S102.

On the other hand, in S118, the normal image data for printing is edited from the end, and the number of printing lines is set (S11).
9). Next, the thermal head 3 is moved according to the dot pattern edited by the motor 94 for one step feeding and printing.
The printing process of the thermal recording sheet 52 is performed for one line by driving 2 (S120), and 1 is subtracted from the number of printing lines to store the number of remaining printing lines (S121).

Next, it is determined whether the number of print lines is 0 (S122). If it is not 0, the process returns to S120, and this process is repeated until the number of print lines becomes 0.

When the number of printing lines becomes 0, printing of the thermosensitive recording sheet 52 is completed. Then, the heat-sensitive recording sheet 52 is sent out to the discharge guide tray 30 (S123), and the process returns to S102.

Next, referring to FIG. 3, the thermal recording sheet 5
The case of printing on No. 2 will be described. First, the heat-sensitive recording sheet 52 inserted in the apparatus is stopped and mounted by a stop mechanism (not shown) at the position of arrow B in the figure. At this time, the thermal head 32 is in the standby state at the position shown by the dotted line in the figure, and the thermal recording sheet discrimination switch 48 is off.
When the plate making key 22 is pressed from the mounted state, the supporting member 3
6 is rotated by the driving force of a motor (not shown), and the thermal head 32 is lifted to the position indicated by the solid line. In this state, the thermal recording sheet 52 is sandwiched between the platen 34 and the thermal head 32, and the thermal recording sheet discrimination switch 48
Turns on. Further, the push-up roller 38 is in contact with the thermal recording sheet feeding roller 42.

After the pressing operation of the thermal head 32 against the platen is completed, the platen 34 and the thermal recording sheet feed roller 42 start to rotate in the feed direction by the driving force of a motor (not shown). The heat-sensitive recording sheet feeding roller 42 is set such that the feeding speed at the time of rotation is slightly higher than that of the platen 34 and the frictional force is set to be weaker than that of the platen 34, so that the heat-sensitive recording sheet 52 sags between the roller 42 and the platen 34. It follows the feed rate. Print data edited by key input is sent as dot information for each line to the thermal head 32 for each step of rotation of the platen 34, and the heat generating element selectively generates heat to generate the thermal recording sheet 52. Is printed and printing is performed.
Even after the printing is completed, the platen 34 and the thermal recording sheet feeding roller 42 continue to feed the thermal recording sheet 52 and feed it to the ejection guide tray 30. After that, the feeding operation is completed, the thermal head 32 is returned to the position indicated by the dotted line, and the operation is completed.

Next, referring to FIG. 4, an original plate 120 for stencil printing.
The case of plate making will be described. First, the stencil printing plate 120 inserted into the apparatus is stopped and mounted by a stop mechanism (not shown) at the position of arrow B in the figure. At this time, the thermal head 32 is in the standby state at the position shown by the dotted line in the figure,
At this time, the thermal recording sheet discrimination switch 48 is off. When the plate making key 22 is pressed from the mounted state, the supporting member 36 is rotated by the driving force of a motor (not shown), and the thermal head 32 is lifted to the position indicated by the solid line. In this state, the stencil printing plate 120 is sandwiched between the platen 34 and the thermal head 32. However, the thermal recording sheet discrimination switch 48 remains off.

After the pressing operation of the thermal head 32 against the platen is completed, the platen 34 and the stencil printing plate feed roller 44 start rotating in the feed direction by the driving force of a motor (not shown). The stencil printing plate feed roller 44 is set such that the feeding speed during rotation is slightly higher than that of the platen 34 and the frictional force is set to be weaker than that of the platen 34.
The slack 20 between the roller 44 and the platen 34 first follows the feed speed of the platen 34. Plate-making data edited by key input at each step of rotation of the platen 34 is sent to the thermal head 32 as dot information for each line, and the heating element selectively generates heat, and the stencil printing master plate is produced. 120 is hot-perforated for plate making. Even after completion of plate making, the platen 34 and the stencil printing plate feed roller 44 continue to feed the stencil printing plate 120, and finally by the feed rollers 46a and 46b.
Send below 0. After that, the feeding operation is completed, the thermal head 32 is returned to the position indicated by the dotted line, and the operation is completed.

In FIG. 5, the thermal head 32 is the material 5 to be heated.
6 shows that the heated material 56 relatively moves in the direction of the arrow while being in contact with 6. In this embodiment, the heated material 56 is the stencil printing plate 120 or the heat-sensitive recording sheet 52. The material 56 to be heated is fed stepwise in the direction of the arrow, and the dot data corresponding to the desired printing or plate making edited in each step is fed to the array of heating elements of the thermal head 32. After the data is confirmed,
Heat is applied to a desired position of the material 56 to be heated by driving the heating element corresponding to the data for a specific time. The operation in each feeding step is repeated to finally complete printing or plate making.

FIG. 6 (a) shows a pattern for making a plate on a stencil printing plate, which is a mirror image when viewed from the front. Since this is a pattern serving as a stamp surface, ink is transferred from the holes punched according to this pattern to the printing paper to obtain a normal image print.

The pattern shown in FIG. 6B is printed on the thermosensitive recording sheet 52. Although this printing is a normal image, it indicates that printing is performed from the end of the printing range. This is so that the printed thermal recording sheet 52 discharged from the discharge port 28 of the stamp device 12 can be directly formed as a normal image on the discharge guide tray 30 as shown in FIG.

As is clear from the above description, in the stamp device 12 of the present embodiment, the user prints on the heat-sensitive recording sheet 52 and confirms the printing surface, and then makes the plate on the stencil printing plate 120. Since it can be performed, the stencil printing plate 120 is not wasted.

The present invention is not limited to the embodiments described in detail above, and modifications can be made without departing from the spirit of the invention. For example, although the input device is a keyboard in the present embodiment, it is also applicable to a stamp device in which character or mark data is input to a reception terminal (not shown) from a personal computer or the like and the plate is made according to the procedure described above.

[0046]

As is clear from the above description,
In the stamp plate making apparatus of the present invention, the user can print on the heat-sensitive recording sheet and confirm the printing surface, and then make the plate on the stencil printing plate, so that the stencil printing plate is not wasted.
