CONSTITUTION:Memory buffers 14a, 14b-14e are provided corresponding to input areas, and shift mode data are written in the buffers with shift mode keys 2a, 2b, 2c designating the shift mode. In inputting key data from the input key, a mode designation data is formed in response to the shift mode data stored in the memory buffers 14a-14e, and the mode designation data is written in a mode storage device 8. Thus, the shift mode is set automatically.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shift mode control system for controlling the left state of an input key in a video terminal device that inputs V7tt'va from a keyboard or the like that exchanges information with a computer in an interactive manner.

Conventionally, when inputting data from a keyboard in an interactive manner with a computer, the shift mode of the input keys has been designated by the operator's key operations. For example, in a hospital counter service, etc., the display screen [
flt- As shown in C1, data input canier (1&) (it))...(1・] is defined for multiple items in C1, and when the operator inputs data Y to each input canier, ``Think name'' is in hiragana mode, ``z patient shoulder'' is in alphanumeric mode, and ``5 drug names'' is in kana mode.
The operator's input work was very poor. In addition, incorrect input due to an operator's operational error is unavoidable, and the operator must re-enter the correct data upon discovering the input V, which requires a great deal of effort on the part of the operator.

Therefore, in order to reduce the operator's labor to some extent, we will be able to reduce the burden on the operator if there is an erroneous input due to key operation.

One possibility is to have the computer notify the operator in some way, but in order to do this, not only a program to judge erroneous input, but also a program for searching for cutlery etc. is 8 east and 10 grams. Labor costs for each hour of increased volume are unavoidable.

The present invention has been made in view of this point, and in the video terminal i1 in which the data input channel is predetermined, a memory buffer corresponding to the input channel is provided, and the memory buffer 1: shift mode data is stored in advance. The present invention provides a novel shift mode control method in which the left mode data is written in advance, and when the data is input using the input key, the left mode data is read out and the shift mode χ is automatically set in accordance with the data.

The present invention will be explained below with reference to the present invention.

By the way, in this embodiment, one character code is a JI88 unit code (hereinafter referred to as "JI88 unit code") consisting of 8 characters per character.

ANK code) and JI8 consisting of 16 bits per character.
We deal with Kanji codes (hereinafter referred to as Kanji codes), and in Figure 1 (from a single input key such as ol), ANK
Five types of character codes are generated: alphanumeric mode IAJ of code, kana mode "i J, alphanumeric mode rAJ of kanji go F, kana mode "i" and hiragana mode "i", but shift mode key (2 &) ( 21)) There are six types of specifications in (20): alphanumeric mode, kana mode, and hiragana mode.

Therefore, before explaining the operation t', first, the memory buffer (
14a) (14b) and (14e)
Figure A) ~ (C)? I will explain while referring to it.

The memory buffer consists of a ≦-display character section (upper row) and an attribution section (lower row) as shown in Figure A1 (as shown in Figure A1), and the ANK code I: is lit as shown in '@3 Figure B);
, has a capacity of 2 bytes for one character, and is configured so that an 8-bit character code is stored in the display character section and 8-bit attribute data is stored in one tribyte section. . or.

For kanji board C2, as shown in Figure 3 (b).

One character has a capacity χ of 4 bytes, an 8-bit 7-bit character code M2R is stored in the display character section, an 8-bit character code LSI is stored in the 1-bit unit section, and The shift specification data that specifies the shift mode is displayed in the character section;, and.

It is configured such that attribute data is stored in one unit.

Here, in the ANK code, the 7th bit of the character code is defined as "O" in alphanumeric mode and "1" in kana mode, so in this example, the 7th bit of the character code is used as shift mode data. We are using. or,
1 Tribute data is data that specifies the display state of characters.
86 bits, write to each 4r1J' in the 4th bit (from 2, specify 8-tube light, blink, and inverse, respectively. Therefore, the 7th bit of the attribute data is rOJ, and this data is In the code, 1 tribute section 1; has been written.

However, in the kanji code, there is a 7th part in the totapute part.
Since the LSI is configured to store the character code in which "1" is written in the bit, the 7th bit of one total bit χ In this embodiment, the memory buffer stores the NK code χ that should be input. 1 or the kanji code is used as shift mode data to determine whether the input character is the kanji area. Furthermore, the shift designation data corresponds to data for designating the shift mode in Kanji area 1; In this way, in this embodiment, the shift mode data is the 7 bits of the 1 tribyte part of the kanji area for ANK y7, the 7th bit of the character code for ^NK data, and the 7th bit of the character code for kanji niji 1. Shift specification data is used.

Therefore, to explain counter operations at a hospital as shown in the display screen in Fig. (14a)
(14b) - (14e) +: +t Shift mode data is sequentially scanned from the host computer to set the shift mode suitable for inputting data for each item 1 of counter operations, such as patient name, patient 41, etc. . That is, input the data (to set the appropriate shift mode, the attribute data, shift specification data, and space code as the character code are input into the memory buffer (14&) (141) for each character)... (14・l: Written sequentially.

When the writing of each data to the memory buffer is completed, the screen memo q of the display device #(9) is sent from the host computer u51 so that each item is displayed as shown in OR'rα (FIG. 1 B). Note: Display data corresponding to each item is transferred. When the transfer of the display data of each item is completed, a control signal is given to the 1 address designation part (134-), and the address designation part (IsJ) is sent to the memo 5 buffer (141) corresponding to the first input canister (1&). Data corresponding to the first character number 2 of the selected memo pad 1 (14 &) is read into the data creation section C.

Data creation 6. At the part value η, as shown in the flowchart of FIG. 4, first, a) '@7 bit of the 5-bit part is read and it is determined whether it is "0" or "1". "O"
If so, it is an ANK code, so the 7th bit of the character code part is read and the rOJ rl shift mode memory path (
If it is "1", it is a Japanese character, so it is written in the shift mode storage circuit (8) as "rot"v mode designation data.

Also, if the 7th bit of 1 tribyte part is "1", alphanumeric mode F, kana mode, hira IJ, rlo
J is written. Then, the shift designation data from the data creation section ση causes the corresponding display lamp to emit light via the display body movement path (6), thereby notifying the operator that the shift mode has been automatically switched to C2.

With the shift mode set like this.

%The first character of the selected memory buffer (141L) corresponds to the address to which it should be entered.0RTt13 Go to the screen! 77 (1&) first character χ input position is Khan A/T! 'The operator moves to the position 13)? The operated input key (3) C: The corresponding key data is supplied from the key data generation circuit (5) to the conversion section α.

Here, if the input key (31) is operated, for example, an input key such as 01 in FIG. Memory buffer 1 to write (read the 7th bit of the first character 7 of 14aJ [butte section 4],
It is determined whether the memory buffer 1 is the ANK area or the kanji area y1. Then, the next ζ2% mode storage circuit (8) is read by the mode designation data creation section, and this data is judged.

Since this is alphanumeric mode, it is converted to the character 2 corresponding to the key data Y rAJ, and when the data is ``ol'', it is kana mode, so the key data is ``i1'', and when it is ``1Q'', it is kept. Tan each tr, "AJ, rl + J, ri"

The corresponding characters are displayed at T113.

When the character code is written to the first address of the memory buffer (14&), the address specifying section 1 selects the next character of the memo 5/7 buffer (14a).

Thereafter, as described above, mode designation data is created by the data creation unit 117), and the shift mode storage circuit (81≦

When the operator operates the input key (3), the character code j≧ is generated from the converter, and the memory buffer (141
The corresponding address (2) of L) is embedded with this character code.

In the above manner, inputting data for one item in the counter operation is completed, and when the operator performs a key operation to input data for the next item (2), the address specification section α9#1 The memory buffer (1m) 3'% corresponding to the input canister (1b) of the item is selected, and the automatic C-shift mode is subsequently set in the same manner as described above.

By the way, in the present invention, a memory buffer (141L) is used.

Corresponding mode child material i data is generated from the mode f-leg data generation circuit (4), and this data is written to the shift mode storage circuit (80; and stored in the memory buffer! (14 &)
14tl) -- Since the mode designation data set and processed by (146) is erased, priority is given to switching the shift mode using the shift mode key.

The corresponding character code is output from the converter.

1. In this embodiment, since ANK code and Kanji code are used as one-character code, the 7th bit of shift mode amount data indicating whether the memory buffer is ANI area, Kanji work y1, or Y is selected. )! However, if you use only 60,000 codes, either ANK code or Kanji code, the 7th bit of 1 tribyte part is used as shift mode data. There is no need to use it, and therefore, in such a case, the conversion unit 08 can convert only the data in the lift mode storage circuit (8) to the key data from 6-Steamed Oysters (31). In Embodiment C2, the number of types of displayed characters is 5N, but the configuration is such that only three types, alphanumeric, kana, and hiragana, can be specified using the shift mode key (31).

If the types of characters to be displayed and the types specified by the shift mode key are the same, N types, and if the mode specification data representing these N types is written to the YV soft mode storage circuit (8), the code will be written to AN. Even in the case where both codes, ie and kanji code, are used, the conversion unit u8 can still convert the key data from the input key to the character code based only on the data in the shift mode storage circuit (8).

The left mode control method of the present invention is as described above.

A memory buffer 1 corresponding to the data input crab 51 is provided,
Load shift mode data t-1 that specifies the second shift mode in memory buffer C, and when inputting data using the input key, automatically set the shift mode based on the shift mode data of memory buffer 1. C;
Therefore, the operator is not responsible for operating the shift mode key C2 to -off, and does not need to be conscious of the output state aj2.

It has a great effect on saving one hour of labor and preventing incorrect input.

Furthermore, in the present invention, the shift mode data is written for each character input to the memory buffer, so it is not only easy to specify the shift mode for each character. , the shift mode change by the operator's V-ftkey is performed for each character C2, and has the advantage that changing the shift mode by other characters in the same memory buffer 1, ζ2, V-ftkey I: has no effect. .
