Abstract

PURPOSE:To use one set of CRT terminal equipment in various ways by preparing two kinds of business OSs, for a magnetic disk device of a terminal control device, and switching the OS by a switching operation from a CRT terminal. CONSTITUTION:When a business CRT terminal equipment 1 is used as a standard function terminal equipment of a word processor, a TSS function, etc., an OS of a standard function is designated from a keyboard 2. The standard function OS is used by calling an OS program from a magnetic disk device 3, and storing it in a core memory of a terminal control part 4. In this regard, by an OS switching operation from the keyboard 2, a menu screen for switching the OS is displayed from a menu file of the magnetic disk 3. In this state, the OS program to be called is selected from the menu screen and inputted to the keyboard 2.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a CRT terminal device, and in particular to a CRT terminal in which a dedicated terminal for one business is shared with a dedicated terminal used for another business (word processor, TSS terminal, etc.). Regarding terminal devices.

[Conventional technology]

Conventionally, when a single CRT terminal device is used as an online terminal for a certain business, the terminal's operating system program (hereinafter referred to as O8) is different from the standard O8, so the functions that the terminal device has as standard functions (for example, word processing, Sosa function.

TSS terminal function) could not be used.

(Problems to be Solved by the Invention) Since the functions of conventional CRT terminal devices do not allow the use of standard functions, they can only be used as online terminals dedicated to certain types of business. install a set of terminal equipment with standard functions, or
There is a drawback that a system creation work must be performed to replace the RT end incomplete cover installation 8. Also, C
Even if the RT terminal device is a terminal device that has a multi-job function, its O5 is different from the standard O8, so the standard function cannot be used even if it is operated with a single job.

[Means for solving problems]

A CRT terminal device of the present invention is a CRT terminal device that performs a first task using a first operating system program, and includes a storage means that stores in advance a second operating system program that performs a second task; and input means for issuing a command to replace the first operating system program and the second operating system program.

〔Example〕

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

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, and FIG. 2 is a chart showing an example of the format of a menu file.

Referring to FIG. 1, an embodiment including a CRT r4 terminal device 6 of the present invention includes a CR7 display 1, a keyboard 2, a magnetic disk 3, a terminal control unit 4, and a communication interface 1.
1 are connected by a data bus 100.

In certain businesses that require online data exchange (for example, travel business, real estate brokerage business, etc.), in addition to the magnetic disk 3 as a storage device, the terminal control unit 4 can also be controlled from the keyboard 2 as an input device. In addition, data is exchanged with other CRT terminal devices through a communication interface 11 consisting of a modem, etc., and a communication line 101, and data input through the communication line 101 and communication interface 11 is transmitted to the CR7 display 1. When recording is necessary, the contents are output from a printer connected to the data bus and used for business purposes.The OS program that controls this business is the same as the standard OS.
The program is stored in advance in the core memory of the terminal control section 4 from the magnetic disk 3 storing the program.

In addition, when using standard functions such as the word processor function and TSS function, the OS program for the standard function is called up from the magnetic disk 3 storing the standard function OS program in advance and stored in the core memory of the terminal control unit 4 according to a designation from the keyboard 2. (It will replace the O8 for business use) to use standard functions.

In addition, in the O8 switching operation from the keyboard 2, a menu screen for O8 switching is displayed from the menu file (for example, in the format shown in FIG. 2) on the magnetic disk 3. Next, select Call 1-No O8 from the menu screen and enter it on the keyboard 2.
The O8 program selected from the file is called and loaded into the core memory of the terminal control section 4 including the calculator unit by the operations described above.

The functions of the CRT terminal device can be expanded using the method described above.

〔Effect of the invention〕

As explained above, in the present invention, by preparing two types of O8 for business use in the magnetic disk device of the terminal control device, it becomes possible to switch the O8 by a simple switching operation from the keyboard of the CRT terminal. As a result, one CRT terminal can not only be used for one business purpose, but also word processing functions, TSS terminal functions, etc. supported by standard O8 can be used, realizing multiple functions with one device and cost performance of the terminal. It has the effect of dramatically improving
