Abstract

PURPOSE:To attain key lead inputting from a keyboard without being affected by the processing time of a connection device so as to improve processing efficiency by providing a function which promptly displays depressed key contents. CONSTITUTION:A one-line input terminal key setting part 103, a keyboard display control part 104 and a keyboard display part 105 are provided. The depressed key contents are read in the keyboard display control part 104 and they are compared with the content of the one-line input terminal key setting part 103, which is previously set, in the keyboard control part 104. When a compared result does not agree, the depressed key contents are sequentially displayed in the keyboard display part 105. When the compared result agrees, the whole contents displayed in the keyboard display part 105 are eliminated. Thus, the depressed key contents can promptly be recognized without being affected by the processing time of a computer 300.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyboard for a terminal, which is an input/output device for a computer, and more particularly to a keyboard that can immediately display the contents of pressed keys.

[Conventional technology]

Conventionally, in this type of keyboard, character keys are arranged in a matrix, and the contents of the pressed keys are read as key data at a terminal to which the keyboard is connected, and sent from the terminal to a computer.

After the sent key data is processed by the computer, the same key data is sent to the terminal as a response and displayed on the display of the terminal.

[Problem to be solved by the invention]

The conventional keyboards mentioned above have no means to display the contents of the pressed keys, and checking the contents of the pressed keys depends on the processing time of the fun viewer, so it is impossible to check the contents of the pressed keys immediately. There are drawbacks.

[Means to solve the problem]

The keyboard of the present invention is a keyboard for a terminal used as an input/output device for a computer, which has a key matrix section in which character keys are arranged in a matrix, and a keyboard control section that converts signals from the key matrix section into codes. The signal from the input end key setting section, the keyboard display section, and the line input end key setting section is compared with the signal from the keyboard control section, and if they do not match, the signal from the keyboard control section is changed to the keyboard display section. The keyboard display control section has a function of sequentially displaying the contents on the display section and erasing all displayed contents on the keyboard display section when a match is found.

〔Example〕

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

The contents of the pressed key are encoded by the key matrix section 101, controlled by code conversion etc. by the keyboard control section 102, read by the terminal control section 200, sent to the computer 300, and received by the computer 300. It is returned to the terminal control unit 200 as a post-response,
It is displayed on the terminal display section 201. In this embodiment, - line input terminal key setting section 103, keyboard display control section 1
04. A keyboard display section 105 is provided, the content of the pressed key is read by the keyboard display control section 104, and the keyboard control section 104 compares it with the content of the one line input termination key setting section 103 set in advance. If the results do not match, the contents of the pressed key are displayed on the keyboard display section 105.
If the comparison results match, all contents displayed on the keyboard display section 105 are erased.

〔Effect of the invention〕

As explained above, the keyboard of the present invention has a function of immediately displaying the contents of the pressed keys, thereby making it possible to input keys in advance from the keyboard without being affected by the processing time of the connected device. This has the effect of being able to immediately verify errors in the process and making processing more efficient.

Claims (1)

[Claims] In a terminal keyboard used as an input/output device for a computer, the keyboard has a key matrix section in which character keys are arranged in a matrix, and a keyboard control section that converts a signal from the key matrix section into codes. The keyboard display section compares the signal from the one-line input end key setting section with the signal from the keyboard control section, and if they do not match, displays the signals from the keyboard control section in sequence on the keyboard display section. , and a keyboard display control section having a function of erasing all display contents of the keyboard display section when there is a match.
