BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate making apparatus for a stamp original plate of a stamp device for imprinting on the surface of an article, and more particularly to a stencil printing method in which the surface of an impregnated body impregnated with ink is covered with a heat-sensitive stencil sheet. The present invention relates to a plate making apparatus in which a printing master plate is conveyed and the heat-sensitive stencil sheet is heated and perforated by a heating device to form a printing surface.

[0002]

2. Description of the Related Art Conventionally, as an apparatus of this type, a stencil printing plate having a surface of an impregnated body impregnated with ink covered with a heat-sensitive stencil sheet is fed into a plate making apparatus, and a thermal head (provided in the plate making apparatus is provided. The heat-sensitive stencil sheet is heated and punched by a heating device) to form a stamp face portion, and the stencil printing plate having the stamp face portion is attached to a stamp block having a handle, and the stamp block is punched by the stamp block. 2. Description of the Related Art There is known a stamping device that imprints a printing master plate to form characters or figures on the surface of an article.

In such a stamping device, characters, figures, etc. are input by a keyboard or the like, and the thermal head heats and punches the heat-sensitive stencil sheet in accordance with the input, and the state of the stamp surface at this time is displayed on the liquid crystal display. It is supposed to be displayed.

However, the perforation resolution for thermal perforation by the thermal head is much higher than the display resolution of the liquid crystal display, and it is attempted to confirm how a stamp image is formed after inputting data with a keyboard. However, only the outline of the stamp image can be displayed on the liquid crystal display. Therefore, in order to confirm the actual stamp image, there is only a method of making a trial press or judging by observing the stamp image. If the formed stamp image is not what the user desires, the stencil printing You have to throw away the original plate.

As a countermeasure against this, after inputting data for stamping with a keyboard and before heating and punching the stencil printing plate, a thin thermosensitive recording paper is inserted into the plate making apparatus,
It is conceivable that thermal recording is performed by a thermal head, and this thermal recording sheet is discharged to the outside to check the stamp image.

[0006]

However, since the stencil printing base plate has a structure in which the surface of the ink impregnated body is covered with the heat-sensitive stencil base paper, the thickness of the stencil printing base plate is equal to the thickness of the heat-sensitive recording paper. More than double.

Therefore, a complicated mechanism is required for realizing the same thermal perforation or thermal recording using the thermal head and discharging it to the outside. Further, as shown in FIG. It is necessary to provide a separate transport path for the transport path A for the recording paper and a transport path B for the stencil printing plate.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to reliably convey both a heat-sensitive recording sheet and a stencil printing plate along one conveying path. An object of the present invention is to provide an inexpensive plate-making apparatus with a simple structure capable of thermal recording and thermal perforation.

[0009]

Therefore, according to the present invention, a stencil printing base plate in which an impregnated body impregnated with ink is covered with a heat-sensitive stencil base paper, and a heat-sensitive recording sheet are detachably mounted. And a heat-sensitive recording sheet mounted on the transport jig, while heat-punching the heat-sensitive stencil sheet of the stencil printing plate mounted on the transport jig and provided along the transport path of the transport jig. And a carrying means for carrying a carrying jig along the carrying path so as to pass through the heating means.

[0010]

In the present invention having the above-mentioned structure, the stencil printing master plate or the heat-sensitive recording sheet is mounted on the carrying jig, and the carrying jig passes the heating means along one carrying path by the carrying means. Be transported. The stencil printing plate mounted on the conveying jig is heated and punched by this heating means,
On the other hand, the thermosensitive recording sheet mounted on the carrying jig is subjected to thermosensitive recording. Therefore, the perforation pattern for heating and perforating the stencil printing plate is heat-sensitively recorded on the heat-sensitive recording sheet.

Next, the operation of the stamp device of the present invention will be described.

First, the point of confirming the actual stamp image after the data for forming the stamp image is input by the keyboard 2 shown in FIG. 1 will be described. The operator rotates the medium support plate 68 of the carrying jig 76 so that the protruding portion 65a of the backup rubber 65 is carried by the carrying jig 76.
The central opening 66 of the frame 61 is set so as to penetrate downward. At this time, the protruding portion 6 of the backup rubber 65
A heat-sensitive recording paper 50B is preliminarily peelably adhered to 5a. The backup rubber 65 is positioned by fitting a positioning hole 65b into the positioning protrusion 61a of the frame 61. After this, the operator closes and rotates the medium support plate 68 to hold the backup rubber 65 on the upper surface of the frame 61.

After that, the transport jig 76 is inserted into the insertion opening 6 of the plate making apparatus 1 so that the heat-sensitive recording paper 50B faces downward. Then, the shutter pair 30 moves to the transport jig 76.
The first rail 62 and the second rail 62 'swing in the direction of opening the conveyance path against the spring force. This time,
In the stop frame 80, since the stop plate portion 25b is in contact with the upper guide plate 43 from below by the action of the tension spring 27, in other words, the stop plate portion 25b enters the transport path of the transport jig 76. Therefore, the transport jig 76 can be inserted into the plate making apparatus 1 until the tip thereof collides with the stop plate portion 25b (see FIG. 1). In this state, the upper conveying roller 13a is engaged with the second rail portions 62 'and 62' of the frame 61 and is moved slightly upward against the compression spring 114.

When the plate making key 4 is depressed from this state, the thermal head holding plate 16 is rotated clockwise by the tension spring 18 in FIG. 5 by the rotation of the motor via the cam mechanism, and the thermal head 15 is moved to the thermosensitive recording paper. It is pressed against 50B from below. In this way, when the thermal head holding plate 16 is rotated clockwise, the constraint of the rotational movement of the roller holding plate 19 by the connecting wire 14 is released, so that the roller holding plate 19 is pulled by the tension spring 24. 5 Rotate in the counterclockwise direction. That is, the roller holding plate 19 rotates in conjunction with the thermal head holding plate 16.

When the roller holding plate 19 rotates counterclockwise, the operating pin 22 projecting from the roller holding plate 19 engages with the engaging surface 25a of the stop frame 80 and resists the tension spring 27. This is rotated clockwise in FIG. Therefore, the stop plate portion 25b of the stop frame 80 separates from the upper guide plate 43 and moves below the lower guide plate 44. That is, the stop frame 8 is moved from the transfer path of the transfer jig 76.
The stop plate portion 25b of 0 is retracted, and the transport jig 76 can be transported.

Thereafter, the transport motor is rotationally driven to rotationally drive the platen 12, the upper transport roller 13a, the upper discharge roller 41, and the lower discharge roller 42, and the heating elements arranged in a line in the thermal head 15 are input. By selectively generating heat according to the data, heat-sensitive recording is performed line by line on the heat-sensitive recording paper 50B held by the transport jig 76. When the transport jig 76 reaches between the upper discharge roller 41 and the lower discharge roller 42, the transport jig 76 spreads the upper discharge roller 41 and the lower discharge roller 42 and intrudes into the space between them. Is discharged and transported.
After the heat-sensitive recording is completed, the transport jig 76 is moved from the discharge port 100 to the plate making apparatus 1 by the upper discharge roller 41 and the lower discharge roller 42.
It is discharged outside. After that, after the motor is stopped, the motor is stopped by a predetermined amount, so that the thermal head holding plate 16 is rotated counterclockwise in FIG. 5, and in conjunction with this, the roller holding plate 19 is rotated clockwise. Then, the stop frame 80 is rotated counterclockwise. At this time, stop frame 8
In the case of 0, the stop plate portion 25b enters the conveyance path, collides with the upper guide plate 43, and is stopped rotating.

By looking at the heat-sensitive recording paper 50B held by the transport jig 76 discharged to the outside of the apparatus in this way, the operator can directly check the stamp image to be made.

Next, the plate making after confirming the stamp image will be described.

First, the operator rotates the medium support plate 68 of the carrying jig 76, takes out the backup rubber 65, and replaces the stencil printing plate 50A shown in FIG. 3 with the carrying jig. Set to 76. At this time, as in the case of the backup rubber 65, the heat-sensitive stencil sheet 74 is turned down and the central opening 6 of the frame 61 of the carrying jig 76 is set.
The heat-sensitive stencil sheet 74 is set so as to project downward from 6. The stencil printing plate 50A is positioned by fitting the positioning holes 75a into the positioning projections 61a of the frame 61. After this, the operator closes and rotates the medium support plate 68 to move the stencil printing plate 50A.
Are held on the upper surface of the frame 61.

After that, the carrying jig 76 is set to the heat-sensitive stencil sheet 7.
4 from the insertion opening 6 of the plate making apparatus 1 so that
The tip is inserted into the apparatus until it abuts against the stop plate portion 25b of the stop frame 80.

In this way, when the plate making key 4 is depressed,
In the same manner as in the above case, the thermal head holding plate 16 is rotated so that the thermal head 15 moves to the stencil printing plate 50A.
The heat-sensitive stencil sheet 74 is contacted from below. Further, the roller holding plate 19 is rotated so that the lower carrying roller 13b presses the carrying jig 76 against the upper carrying roller 13a, and the stop frame 80
The stop plate portion 25b is retracted from the transport path. After that, the platen 12, the upper transport roller 13a, the upper discharge roller 41, and the lower discharge roller 42 are rotationally driven, and the heating elements arranged in a row in the thermal head 15 are selectively heated according to the input data. , Transport jig 7
The heat-sensitive stencil sheet 74 of the stencil sheet 50A held in 6 is heated and punched line by line. Transfer jig 76
When the sheet reaches between the upper discharge roller 41 and the lower discharge roller 42, the conveying jig 76 spreads the upper discharge roller 41 and the lower discharge roller 42 and intrudes into the space between them.
1, 42 are discharged and conveyed. The transport jig 76 which has been heated and punched is discharged from the discharge port 100 to the outside of the plate making apparatus 1 by the upper discharge roller 41 and the lower discharge roller 42.
