Abstract

PURPOSE:To obtain a printing controlling device having CRT that can print ''KANJI'' (Chinese character), graphic, etc. by a general purpose bit image type printing device by attaching an RAM for video signal storing to a controlling device provided with CRT. CONSTITUTION:In a printing controlling device A provided with CRT, a video signal is transmitted from a P/S converter 5 to CRT6 and ''AB'' is displayed on the CRT6. In this case, the video signal is taken simultaneously in an RAM for video signal storage 14. This is read by the CPU1 and sent from a bit data transmitting section 15 to a bit data receiving section 16 of a bit image type printing device B as bit data. Accordingly, the printing device B that receives the bit data stores the bit data in a bit image memory 17, and prints ''AB'' by a printing head 12.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printing control device with a cathode ray tube (CRT) that is capable of printing Chinese characters, figures, etc. displayed on a cathode ray tube (CRT) using a general-purpose printing device.

FIG. 1 is a block circuit diagram showing the configuration of a conventional cathode ray tube-equipped printing control device and a character code input type printing device that display predetermined characters on a cathode ray tube and print the displayed characters on a printing device. In the figure, the print control device A includes a central processing unit (hereinafter referred to as CPU).
(i) S-control program memory (2), display content video random access memory (hereinafter referred to as video-RAM) (8), which stores the character code of the content to be displayed; Character generator (4), parallel
Sorial converter (hereinafter referred to as P/B converter) (5)
It is equipped with a cathode ray tube (hereinafter referred to as CRT) (6) and a CRT controller (gamma) to display predetermined characters on the CRT (6), and is also equipped with a printed character transmitter (8) to control the display contents. The character code is transmitted to the character code input type printing device B.

Then, the character code input type printing device ffi B
The CRT (6) is equipped with a receiving section (9) for receiving the character code transmitted from the printing control device A, a character memory, a character generator 01), a print head controller and a control section (IB). All items that are the same as those displayed will be printed.

In the printing control device having the configuration shown in FIG. 1, when the character "AB" is displayed on the CRT, and when the character "AB" is to be printed, the character "AB" is displayed from the video-RAM (8) to the printer generator (4). ) is sent the character code r41 42J corresponding to the characters "AB", and the generator (4) converts that character code to P/S.
Transmitted to the CRT as a video signal
(6), thereby displaying [AB
J is displayed.

Then, in order to print this, the CPU (1)
RAM (Reads the contents of 81 and displays its contents “
The character code r41 42J of "AB" is transmitted by the transmitter (
8) to the receiving unit (9), stores it in the character memory, and the contents are sent to the character generator 0.
1), the generator (11) converts it into a character pattern, and sends it to the print head (3), thereby printing l'-ABJ.

Since the conventional printing control device with CRT is configured as described above, it is necessary to redundantly provide the character generator (4) and 0η on both the printing control device with CRT side and the printing device side. In order to print kanji, figures, etc., a dedicated and expensive printing device was required.

Therefore, the present invention has been made to eliminate the above-mentioned drawbacks of the conventional technology.
It is an object of the present invention to provide a printing control device with an ORT that can print graphics and the like using a general-purpose bit image type printing device.

Hereinafter, an embodiment of the present invention will be described with reference to FIG. 2, in which the same parts as in FIG. 1 are denoted by the same reference numerals.

In FIG. 2, the CRT-equipped printing control device A of this embodiment includes a video signal storage RAM (RAM) for capturing video signals transmitted from a P/S converter (5) to a CRT (6);
A bit data transmitter (to) is provided to transmit the contents of this RAM (14) as bit data, and the contents displayed on the CRT (6) using a general-purpose bit image type printing device are provided. It is designed to be fully printed.

The printing device B in this embodiment is constructed of a bit image type as described above, and there is no need to provide duplicate character generators as in the conventional example. 1
7) Includes a head (chest), and a control section (gon).

In the CRT-equipped printing control device configured as described above, a case will be described below in which the characters "AB", for example, displayed on the CRT (6) are printed.

First, at this time, when printing control device A is disconnected, a video signal is sent from the P/S converter (5) to the CRT (6) in the same way as before, and "AB" is displayed on the ORT (6). Ru. In this case, the video signal sent from the P/S converter (5) to the ORT (6) is also taken into the video signal storage RAM (1→) at the same time, and is stored in the 0PU (1). is read and transmitted as bit data from the pit data transmitter (to) to the bit image type printing device B.
The data will be transmitted to the bit data receiving section (16).

Therefore, the printing device ff receiving that bit data
B stores all the bit data in the bit image memory (17) and prints the characters rABJ. In this case, the printing device B may be a bit image type general-purpose device, and the conventional There is no need to provide duplicate character generators such as.

Here, we will explain how to import the video signal into the video signal storage RAM (1→) and how to input the video signal into the bit image memory CI.
? ) will be explained with reference to Figure 6.4. Figures 3 and 4 show cases in which one character consists of 8 dots x 8 dots, and the first scanning line (a) and second scanning line in Figure 3 The video signal of the main scanning line (b) is converted to (1a) and (
As shown in 1C), the data is stored in the RAM α for video signal storage, and it is also stored in a bit image memory (B) as shown in 1C, in order to send it to the printing device as bit data. .

6- As described above, according to the present invention, a cathode ray tube is provided, characters of content to be displayed are converted into video signals and displayed by the cathode ray tube, and the displayed content is printed by a printing device. In this printing control device with a cathode ray tube, the distance between the video signal storage random access memory for storing the video signal and the bit data transmitting unit for transmitting the stored contents as bit data to the printing device side is 11 meters. A character generator is not required, the printing device can be used as a general-purpose bit image type printing device, and it is possible to obtain a printing control device with a cathode ray tube that can print Chinese characters and figures.
