Abstract

PURPOSE:To mixingly input from two types of keyboards by outputting the character code of an output from a character keyboard as it is, inputting it to a display device and converting the code of an output from an item input keyboard into a character code string showing item characters so as to input to the display device. CONSTITUTION:If an input is a one from the character keyboard 4, it is transmitted to the display device 2. If it is not the one but the input from the item input keyboard 1, the code showing the start of the input from the item input keyboard is transmitted to the display device 2, after which a coordinate code input from the item input keyboard is converted into the character code string corresponding to the item, and transmitted to the display device 2. Then the code showing the end of the input from the item input keyboard is transmitted to the display device 2. Thus the character keyboard 4 and the item input keyboard 1 need not to be switched to connect, and the outputs from two keyboards can be mixed and inputted to a host computer through the display device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data input device equipped with a character keyboard and an item input keyboard.

[Conventional technology]

As a prior art in this field, Japanese Patent Application Laid-Open No. 60-147824
There is a publication (hereinafter referred to as literature). This document is an open patent publication for Japanese Patent Application No. 59-3363 "Item Input Conversion Device" filed by the same applicant as the present applicant. FIG. 3 is a block diagram similar to FIG. 2 of the above-mentioned document, in which (1) is an item input keyboard, (2) is a display device, (3) is an item input conversion device, and (4) is an item input conversion device. The character keyboard (5) is the host computer.

At the head of each key on the character keyboard (4), the character to be input by that key is written, and when that key is pressed, the character code of the character written at the head of that key is output, and this The character code is temporarily stored in a storage unit (for example, refresh memory) in the display device (2),
The character code stored in this storage unit is read out and converted into a dot pattern of the character by the font memory in the display device (2), and the character code input from the character keyboard is displayed on the display device (2). Dot patterns of characters corresponding to the characters are displayed in sequence.

On the other hand, each key on the item input keyboard (1) is predetermined with the corresponding item character, that is, a predicate or word, or interrupt information or control code. When pressed, a code specifying the key, for example a code representing the coordinate position of the key within the keyboard, is output, and this code is input to the item input conversion device (3). The item input conversion device f(3) converts the coordinate position code input from the item input keyboard (1) into a character code representing each character of a character string constituting the corresponding item character, and outputs the converted code.

The character code output from the item input conversion device (3) is stored in the memory of the display device (2), and the dot pattern of that character is displayed on the display device (2). That is, when one key is pressed on the item input keyboard (1), a dot pattern of character strings forming the item character defined corresponding to that key is displayed on the display device (2).

In order to store a character code string corresponding to the character string displayed on the display device (2) in the host computer (5), the operator inputs a specific control code from the item input keyboard (1) or the character keyboard (4). When inputted, the character code string arranged in the storage section of the display device (2) is written to the storage device in the host computer (5).

[Problem that the invention seeks to solve]

The conventional data input device is configured as described above, so it has a character keyboard (4) and an item input conversion device (3).
) and must be connected to the display device (2), and the switching operation is complicated.

This invention was made to solve the above-mentioned problems, and its purpose is to provide a data input device that does not require switching operations between using a character keyboard and using all item input keyboards. It is said that

[Means for solving problems]

In this invention, an item input conversion device is provided which receives the output from the character keyboard and the output from the item manual keyboard. The code is converted into a character code string representing the item character and input to the display device.

[Effect]

According to the present invention, the outputs from the two keyboards can be mixed and input to the host computer via the display device without switching and connecting the character keyboard and the item input keyboard.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.
In the figure, the same reference numerals as in FIG. 3 indicate the same or corresponding parts, and (30) is an item input conversion device used in the present invention. Also, FIG. 2 is a flowchart showing the operation of the item input conversion device (30), and in FIG.
26) are each step.

The operation of the apparatus shown in FIG. 1 will be explained below with reference to FIG. In step (21), the character keyboard (
4) Make a full judgment to see if there is any input.

If the result of this determination is YES, the input from the digital character keyboard (4) is sent to the display device (2) at step (22). If the result of the determination in step (21) is positive, the process moves to step (23), where it is determined whether there is any input from the item input keyboard (1).

If the result of the determination in step (23) is No, the process returns to step (21). The result of the determination in step (23) is Y
If it is ES, the process moves to step (24), and after sending a code indicating that it is the start of input from the 9-item input keyboard to the display device (2), the process proceeds to step (25), where input from the item input keyboard is performed. The coordinate code input is converted into a character code string corresponding to the item and sent to the display device (2), and in step (26), a code indicating the end of input from the item input keyboard is sent to the display device (2). After sending the data to step (21), the process returns to step (21).

In the above embodiment, in order to distinguish whether the input is from the character keyboard (4) or the item input keyboard [11] on the display device (2), the character Codes indicating the beginning and end of the code string are being sent, but the frequency of input from the item input keyboard (1) is lower than the character keyboard (1).
If the frequency of input from 4) is also large, step (2)
4) Omit (26) and conversely, step (22)
A code indicating that this is a character code to be input from the character keyboard (4) may be sent before and after the character keyboard (4) on the display device (2).
If it is not necessary to distinguish between the input from the item input keyboard (1) and the input from the item input keyboard (1), step (24
), (26) '(il- can be omitted.

〔Effect of the invention〕

As described above, according to the present invention, there is no need for any switching operation between inputting from the character keyboard and inputting from the item input keyboard, and it is possible to input by mixing all inputs from the two types of keyboards. .
