[0002]

2. Description of the Related Art Conventionally, in a heat-sensitive plate making apparatus in which a thermoplastic resin film plate-making base paper is perforated by a thermal head and the plate-making base paper is used as a base plate for manual printing, the portion to be perforated is input and controlled. The stamp part is integrally formed, and a stamp base for printing is separately provided, and the stamped original plate is attached to another stamp base before printing.

[0003]

However, since the conventional heat-sensitive plate-making printing apparatus is constructed as described above, it is necessary to replace the original plate by itself after each perforation and perform printing. It took a lot of time and effort to print the numbers that changed to. Further, a method of printing by providing a printing portion on the main body itself without providing a separate stamp table is conceivable, but the main body is too large and heavy to print by hand at an arbitrary position.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to prepare a master plate each time even when continuously changing numbers or the like are continuously printed. It is an object of the present invention to provide a heat-sensitive plate-making printing apparatus capable of continuously producing an original plate and easily and continuously printing without the need to replace and print by itself.

[0005]

In order to achieve this object, a heat-sensitive plate making / printing apparatus of the present invention outputs various control signals in response to input means for making a master plate and signals from the input means. A control main body having control means for overall management, and display means for displaying by a signal from the control means,
Punching means for punching the plate-making base paper by a signal from the control means of the control main body, plate-making base paper feeding means for sending the plate-making base paper by a signal from the control means of the main body part, and printing on a printed matter A plate making base paper unit including a printing means, a plate making base paper punched by the perforating means and fed by a predetermined amount by the plate making base paper feeding means and used for printing by the printing means, and a plate making base paper unit attaching / detaching means capable of attaching / detaching the plate making base paper unit. And a plate-making printing body having.

The plate-making base paper unit includes a plate-making base paper supply unit for supplying the plate-making base paper stored in a roll form, a plate-making base paper winding unit for winding the plate-making base paper, and a printed matter through a perforation unit of the plate-making base paper. And an ink supply section for supplying ink to.

[0007]

The heat-sensitive plate-making / printing apparatus of the present invention having the above structure is divided into a control body and a plate-making / printing body, and only the means necessary for perforating the original plate and printing are housed in the plate-making / printing body. Can be used as a small print actuator.

Further, by adopting an integrated plate-making base paper unit structure capable of continuously punching while rolling a roll-shaped plate-making base paper, continuous numbers can be printed continuously without having to replace the original plate. At the same time, the platemaking base paper can be easily replaced.

FIG. 6 is a system block diagram of the present invention, and the operation will be briefly described using this.

The control body 1 has a control board 8 as a control means 7, a keyboard 6 as an input means 5, and an LCD 4 as a display means 3. The plate-making printing body 10 includes
There are a thermal head 20 as the punching means 18, a stepping motor 25 as the plate making base paper feeding means 24, a plate making base paper detection sensor 23, and a print detection sensor 28.

The control board 8 has a CPU 47 for comprehensively managing input information and outputting various control signals, a power supply circuit 48 for supplying power to the control board 8 and the like, and the CP.
There is a clock circuit 49 for operating the U47.
The input of the CPU 47 is a signal from the keyboard 6, a signal from a platemaking base paper detection sensor 23 that detects whether the platemaking base paper unit 14 is present or not, and a print detection sensor that detects whether or not a printing operation is performed. When there is a signal from 28 and the plate-making base paper detection sensor 23 determines that the plate-making base paper unit 14 is not present, the punching is not performed.

The plate-making base paper unit 14 is a plate-making printing main body 10.
LCD with the keyboard 6 while it is set to
When an input command is issued while looking at 4, the CPU follows the input command.
47 issues a punching command to the thermal head 20 in the plate-making printing main body 10 and a sending command to the stepping motor 25 to perform a predetermined punching. When the punching is completed, the stepping motor 25 sends a command to send the punched base paper 19 by a predetermined amount to a position where printing can be performed, and the print detection sensor 28 waits until a print detection signal indicating the end of printing is output. When printing is performed manually and a print detection signal is output, the next punching operation is started depending on the state of initial input designation.

For example, in the case of printing consecutive numbers one after another, when the initial value 00000001 is printed once, when the next number 00000002 is printed, when the initial value 00000001 is printed by the above procedure, the print detection sensor 28 A print end signal is output,
When the CPU 47 issues a punching command sending command for punching the next numerical value 00000002, when the punching is completed, the CPU 47 sends a command for sending a predetermined amount to a position where printing can be performed. After that, the process waits until the print detection sensor 28 outputs a signal indicating the end of printing. Thereafter, by repeating this, it is possible to continuously perform punching and printing.
