Abstract

PURPOSE:To use many kinds of keyboard character arrays, by enabling the contents of a storage device storing a Japanese data table to be read out/written, and adding the keyboard with a means to read out the sheet number of keyboard character array. CONSTITUTION:Just after turning on a power supply, a command is outputted from a CPU 1, a keyboard character array sheet number set up in the keyboard (KB) 8 is read out, a Japanese data table DTB corresponding to the number is loaded to an RAM 20 through a common bus interface IF 7. After completing the load, the KB 8 is turned to keying waiting status as input enabled status. When the keyboard character array on the KB 8 is changed, input from the KB 8 is disabled because the loaded DTB is changed and an interruption is outputted to the CPU 1 through the IF 7. Detecting that the factor of the interruption is the change of the charactor array sheet, the CPU 1 reads out the sheet number and loads a corresponding Japanese DTB to the RAM 20. A microprocessor 5 reads X, Y coordinates inputted from the KB 8 and reads out the corresponding Japanese data from the RAM 20 to convert the data.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a Japanese data input device for inputting Japanese characters used in a processing device such as an electronic computer, and particularly to changing a Japanese data table thereof.

FIG. 11 is a block diagram showing an example of a conventional Japanese data input device.

1 (11 is a central processing bag f (hereinafter referred to as CPU)

3) is a common bus, (4) is a Japanese data input device, and (5) is a Japanese data input device.
) is the microprocessor that processes the signals of this Japanese data input device, and (6) is the microprocessor (5) that processes the signals of this Japanese data input device.
) a control storage device that stores essential microprograms; (7) a common bus; (3) a microprocessor (5);
(8) is a keyboard that generates XY coordinate data or binary data corresponding to Japanese candy data input by Japanese keyboard input; +9) dThis keyboard ( 8) and the microprocessor (5), a keyboard interface that mediates the transmission and reception of data, a*U keyboard (8)
This is a read-only storage device (hereinafter referred to as ROM) that stores a Japanese data table corresponding to XY coordinate data or binary data from .

In the Japanese data input device (4) configured as described above, the XY coordinates input by the keyboard (8) are read into the microprocessor (5) via the keyboard interface (9). The read XY coordinates are converted into Japanese data by reading the corresponding Japanese data from the Japanese data table written in ROM0OK by the microprogram stored in the control memory f:location (6)K.

The operation during this time will be explained with reference to the examples shown in Figures 21-1 and 3. Here, Fig. 2 is a character arrangement diagram showing an example of the character arrangement of the keys of the keyboard (8), and Fig. 3 corresponds to this character arrangement diagram. It is a Japanese data table configuration diagram showing an example of a Japanese data table that has been written.

Now, for example, if you input the character ``Ai'' on the keyboard in Figure 2, the coordinate data Y=0, Coordinate data from the word data table Y=0.X=
Japanese data r 3026Jt corresponding to 2' is imported and sent to the CPU via the common bus interface (7).
(The cPU (1) checks the cause of the interrupt, and if it is a read request from the Japanese data input device (4), issues a data import command and reads the Japanese data r3026J. .

However, the Japanese data input device ^゛(4) uses a microprogram based on the XY coordinate system or binary data to refer to a Japanese data table stored in a ROM (10K) and convert it into Japanese data. However, regarding the character arrangement on the keyboard, it is necessary to prepare a wide variety of character arrangements depending on the field of data to be input and the familiarity of the operator, and there are also requests to change and add characters as the system is upgraded. If this occurs, a new ROM tIO must be manufactured each time.For this reason, it is expensive and uneconomical for the user to have multiple keyboards for each field, and the manufacturer From the side, there was a drawback in that many types of ROMs had to be prepared for each user.

This invention was developed in order to eliminate the drawbacks of the conventional devices as described above, and in order to provide flexibility in the keyboard character arrangement, it is possible to use Japanese data that allows the use of many types of keyboard character arrangement. The purpose is to obtain an input device.

FIG. 4 is a block diagram showing one embodiment of the present invention.
(1) to (9) indicate the same numbers as those in FIG. 1. , Kan is a read/write storage device (hereinafter referred to as RAM) into which Japanese data tables corresponding to the keyboard character arrangement are loaded from the central processing unit (1).

The Japanese data input device (4) according to the present invention has two operating modes. The first mode is the Japanese data table f CPU (1) to common bus interface (7)
This is a load mode in which the data is loaded into the RAM (e) via This is a data input mode in which this data is sent from the microprocessor (5) to the CPU (11K) via the common bus interface (7).

Load mode is used immediately after power-on, or when the operator's keyboard character arrangement, & history. CP immediately after power on
U Issues a command to read the character arrangement sheet number of the keyboard (8) from (1), reads the character arrangement sheet number set on the keyboard (8), and displays the Japanese candy data table corresponding to this registration number using the common bus interface. Load it into RAMtA via (7). When the loading is completed, the keyboard (8) is inputted and the system waits for key input.

When the operator sets another character layout sheet to the keyboard (18) in order to change the character layout of the keyboard (8), the sheet number of the Japanese data table and the character layout sheet number of the keyboard are different. keyboard (8
) and generates an interrupt to the CPU (1) via the common bus interface (7).

The CPU (1) checks the interrupt cause and uses the keyboard (8)
When it learns that the character arrangement sheet has been changed, it issues a read command to cut off the character arrangement sheet number, and stores the corresponding Japanese data table in RAM m via the common bus interface (7). Load. When the loading is completed, the keyboard (8) becomes ready for input and waits for human input.

Next, in the data input mode, the XY coordinates of the keyboard (8) specified by the operator are read into the microprocessor (5) via the keyboard interface (9).

Loading 7'1. The X and Y coordinates are converted by reading the corresponding Japanese data from the Japanese data table in RAM□□□1 by the microprogram.

The above operation will be specifically explained using examples shown in FIGS. 2 and 3.

For example, if you input the character "love" on the keyboard, the coordinates Y=O,
X=2t Microprocessor (5) reads and coordinates Y
=O, Japanese data code corresponding to X=2 r 302
6J and sends an interrupt to the CPU (11) via the common bus interface (7).

The CPU (1) checks the interrupt device, learns that the request is from the Japanese data input device t (4), issues a data read command, and reads the Japanese data code r3026J.

It works as above, so if you use multiple character array sheets,
By preparing a corresponding Japanese data table, the operator can use a keyboard with the optimal character arrangement for the field of input data.

In the above 6r2 embodiment, the keyboard (8) is equipped with a means to read the keyboard character arrangement sheet number, but if the keyboard character arrangement sheet only needs one type, the keyboard character arrangement Omit the method of finding the sheet number [
-It's okay.

As explained above, this invention combines a storage device storing a Japanese data table with a readable/writable storage device and adds a means for reading 11 sheet numbers of keyboard characters to a single keyboard. This method has the advantage that it can be used for a wide variety of keyboard character arrangements in a word data manual device.
