Abstract

PURPOSE:To perform key operations according with the standard code of an optional country of the world without complicated replacement by setting preliminarily key patterns peculiar to individual countries in a pattern generator and identifying them with ID codes. CONSTITUTION:An identifying code generating part 13 sends an ID code to the CPU side in response to power-on or key operation of a keyboard. In the CPU side, the sent ID code is set to a register 22. A CPU 21 refers to the ID code set to the circuit 22 to interpret key data sent from a key data generating part 12. That is, the CPU 21 accesses a pattern generator 24 with an address, where some pattern is set, in accordance with the ID code to take out a desired pattern. Taken-out pattern is processed in a display circuit 23 and is sent to a display device 30. Thus, key operations in accordance with the standard code of an optional country of the world are possible without complicated replacement.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information processing system having a keyboard,
In particular, the present invention relates to an information processing system in which a keyboard section and a central processing section are housed in separate housings and connected by a cable.

In the above system, where the keyboard section and the central processing section that processes the key data sent from the keyboard section are configured in separate casings, the key code corresponding to the operated key (for example, A8CTT code) is converted and stored in the keyboard casing. It was designed to be sent from the body to the CPU chassis. Based on the sent key code, the CPU accesses the pattern generator in which pattern data corresponding to the key is stored, reads it out, and stores it in a display memory 4). The pattern data stored in this memory is then sequentially read out and displayed on a display device such as a CRT. This will of course be explained with reference to FIG. In the figure, 1 is a keyboard housing, 2 is a CPU housing, and 3 is a display device. The keyboard housing 1 includes a key operation section 4 and a key code output section 5 inside, and has a key code corresponding to the operated key (this is predetermined, for example, JIS in Japan).
The code specified by the standard, also ASCII in the United States
code) and transfer it from the output unit 5 to the cable. The transferred key code is input to the CPU 6 in the CPU housing 2, and a pattern corresponding to the key code is extracted from the pattern generator 8.

It is processed by the display circuit 7 and output to the display device 3.

However, because of this configuration, if you want to use an American keyboard instead of a Japanese one, you will have to change the key code creation circuit in keyboard housing 1 from Japanese to American. C accordingly
The PU housing 2 must also be changed from a Japanese JIS code pattern generator to an American one with a CII code pattern generator e. Therefore, depending on the location and purpose of use, the keyboard section and CPU
Changes were necessary for both the department and the department.

An object of the present invention is to provide an information processing system that allows key operations to conform to the standard codes of any country around the world without the need for complicated replacement as described above.

The present invention has a keyboard unit having a means for outputting a recognition code, and a CPU unit having a means for inputting the recognition code transferred from the keyboard unit and selecting a pattern specified by the recognition code. The present invention is characterized in that a memory in which data of each pattern that can be changed depending on each country or purpose of use is stored in advance is selected in accordance with the recognition code of the previous user.

According to the present invention, a keyboard can be used depending on the location or purpose of use, and by generating a recognition code from the keyboard side, the CPU
You can use this to select the specified pattern. Therefore, it is possible to cope with the standard codes of each country and the usage patterns for each purpose without changing the CPU side, and the versatility and operability can be greatly improved.

Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 2 is a system block diagram of one embodiment of the present invention. The system consists of 10 keyboard casings and 20 CPU casings.
and a display device 3o, each connected by a cable as shown in the figure. The keyboard housing 1° has a key operation section 11. It includes a key data creation section 12 and a recognition code (hereinafter referred to as ID code) generation section 13. On the other hand, CPU housing 2o
is CPU21. Register 22 for storing ID code. It includes a pattern generator 23 and a display circuit 24.

The recognition code generation unit 13 first sends the IIJ code to the CPU side in response to turning on the power of the keyboard or operating a key. On the CPU side, the sent ID code is stored in register 2.
Set to 2. The CPU 21 refers to the ID code set in this register 22 and uses the key data creation unit 12.
Interpret the key data sent from.

Here, the key data creation section 12 and the pattern generator 24 will be explained in detail. The conventional key code output unit (5 in Fig. 1) corresponds to the operated key and outputs a predetermined standard code (for example, JI in Japan).
S code, ASCTI code in the United States, etc.) was created and transferred to the CPU side.

However, the key data creation unit 12 of this embodiment does not create a standard code like the conventional one, but creates data (hereinafter referred to as scan code) indicating key numbers assigned in order according to the key arrangement on the operation board. ). That is, for example, when you operate the A" key, 1
Instead of creating a standard code that indicates the person #%”
A "Blue data (scan code) indicating the key arrangement position is created. In other words, whether it is a Japanese keyboard or an American keyboard, the same scan code is created for keys in the same position. Ru.

Therefore, by simply placing templates corresponding to each country on the keyboard, one keyboard can have functions that meet the standards of all countries.

Here, for example, a key that is not in the Japanese JIS code but is in the American ASCII code is the brace key. For example, assume that the key in the same position as the curly bracket key on a Japanese keyboard is the yen key. Since the keyboard itself has the same key as the brace key and the circle key, the key data creation section 12 creates the same scan code and transfers it to the CPU 21. The CPU 21 determines the transferred scan code by looking at the ID code preset in the register 22. For example, if the ID code is a code for a Japanese keyboard, the scan code is recognized as a Yen key. Of course, if the II) code of an American keyboard is set, it will be recognized as a brace key. Since both the pattern corresponding to the circle key and the pattern corresponding to the brace key are preset in different address spaces within the pattern generator 24, the CPU executes the pattern generator at the address where either pattern is set according to the ID code. 24 and take out the desired pattern. The extracted pattern is processed by the display circuit 23 and sent to the display device.

In this way, key patterns specific to each country can be set in advance in the pattern generator, and by identifying these with an ID code, there is no need to replace the keyboard or pattern generator. Alternatively, key operations can be performed according to any purpose, and an information processing system with extremely high operability and versatility can be obtained.

As for the layout, patterns can be set in separate address spaces depending on the type of keyboard, or patterns that can be used in common (for example, alphabetic patterns, numeric patterns, etc.) can be set in a common address space, and special You may also set only those items to different addresses.

Furthermore, the effect of ID code recognition can fully bring out the advantages of the present invention in that even in a conventional system in which a standard code is output from a keyboard, the pattern generator on the CPU side does not have to be changed.
