Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applicable to CRTs used in automatic counseling machines of financial institutions, etc.
The present invention relates to a display control device.

[Conventional technology]

Conventionally, the CRT display control device of this type of automatic machine outputs and displays a guidance screen for guiding customers and the processing results of the central processing unit.

FIG. 3 is a block diagram of an example of a conventional CRT display control system. This control system includes a control section 1, a data processing CRT control circuit 2 connected to the control section 1, a display memory 3 controlled by the CRT control circuit 2, and a character/figure generator. device 4 and CRT display 11
It is composed of Toyoshi.

[Problem that the invention seeks to solve]

The C1 (T display control device) of the automatic machine mentioned above controls only the guidance screen to guide customers and the screen that displays processing results in the central processing unit. Therefore, in order to use the Videotex communication service that will become popular in the near future, there is a drawback that a new Videotex user terminal must be installed.

The object of the present invention is to eliminate such drawbacks and to provide an inexpensive videotex that can be shared.C)1. An object of the present invention is to provide a T display control device.

[Means for solving problems]

The CRT display control device of the present invention controls the input data information and performs raster scanning on the CRT display of characters and graphics.
a first CRT control section that performs display; a second CRT control section that inputs videotex data and controls character and graphic display memory, image memory, and color lookup table to perform CRT display by raster scanning; The screen switching circuit includes a screen switching circuit that switches outputs from the first and second CRT control sections according to a predetermined operation, and a CRT display section that displays the output of the screen switching circuit.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

Fig. 1 is a block diagram of an embodiment of the invention, Fig. 2 f's
FIG. 2 is a perspective view of an example of an automatic consultation machine that is an example of the terminal device of FIG. This embodiment includes a control unit 1, a data processing CRT control circuit 2 connected to the control unit 1, a videotex CRT control circuit 5, and a data processing display control circuit 5 controlled by the CRT control circuit 2. memory 3
A character/graphics generator 4 for data processing, a videotex display memory 6 and a character/graphics generator 7 controlled by a videotex control circuit 5, an image memory 8, and a predetermined color type. It is comprised of a color look-up table 9 for specifying a color to be included, a screen switching circuit 10 for switching between a video signal for data processing and a video signal for videotex, and a CRT display 11.

By adopting such a configuration, by switching the screen switching circuit 10 under the control of the control unit l, the data processing screen display and the Videotex communication service screen display can be displayed using a single CRT display 11. It becomes possible to display.

Thus, using a single C) LT disuill',
Since it displays two different screens, it becomes an inexpensive and compact data processing terminal, and can also function as a Videotex user terminal.

Next, as shown in FIG. 2, the automatic counseling machine 20 used in financial institutions etc. has a CRT display unit 13. Keyboard 14. Magnetic card/magnetic passbook read unit 15.
It is composed of an image form processing unit 16 and the like.

This terminal device allows general customers to normally perform consultation services and reception services for various layers online through the central processing unit without the intervention of bank staff; instead, the customer operates the keyboard 14. This makes it possible to switch this terminal to the Videotex user's hospital bed and provide various information input into the Videotex central processing unit.

〔Effect of the invention〕

As explained above, the present invention adds a control circuit that controls the display screen using the Videotex communication service to a control circuit that controls all of the conventional raster scan type CRT displays, thereby allowing data processing to be performed on the same CRT display. It can be used not only as a terminal but also as a Videotex user terminal, and has the effect of providing terminal equipment such as an inexpensive and compact automatic consultation machine.
