Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a keyboard device, particularly for use in schools, etc.
When a test is administered to students in a class, each student's answer for each period or item of the test is scored 11 1 PI
Or score “O n” and enter it into a computer,
The present invention relates to a keyboard device used when inputting data to a recording medium such as a paper tape punching device or a magnetic tape device.

If each student's answer is correct, they will be given a score of 77, 1, or 91, and if the answer is incorrect, they will be given a score of 77, 1, or 91. , often gives a score of +1 0 11.

In order to input these "1'' or "O" data into a computer for analysis and processing, it can be input directly into the computer via the teletype keys, or by using a keyboard with the same function as the teletype keys. A method of recording on paper tape or magnetic tape via a device is often adopted.

In this case, when inputting data using the commonly used teletype keys, the operator must press the "1" or "0" keys one by one according to the data entry format.

By the way, when a test or a set of practice questions consisting of many booths is given to dozens of students in a class, the amount of data is the product of the number of questions and the number of students, so the amount of data is extremely large. The problem arises that it takes a considerable amount of time to input data! Furthermore, since the amount of keystrokes required for operation is large, various undesirable problems occur, such as operator fatigue and increased occurrence of errors in keystrokes and data input formats.

These undesirable problems often appear especially when beginners are sloppy with the operation.

Moreover, when considering use in schools and the like, the operator is often a beginner, such as a teacher, so an input device that is easy to operate and requires as few keystrokes as possible is required.

An object of the present invention is to provide a keyboard device that satisfies these requirements.

The keyboard device of the present invention includes (1) n memory circuits corresponding to n students in a class, n set keys corresponding to each of these memory circuits, and a state of the n memory circuits. n indicator lamps to display, a preset key to preset the n memory circuits to "1" or "0" all at once, and a reset that forcibly returns the n memory circuits to their initial state all at once. a scanning circuit that scans the states of the n storage circuits, a drive pulse generation circuit that drives the scanning circuit, and when n drive pulses generated from the drive pulse generation circuit are counted. It is composed of a counting circuit that returns n memory circuits to the initial state and stops the operation of the drive pulse generation circuit and the scanning circuit, and a start key that starts the generation of drive pulses from the drive pulse generation circuit. .

In other words, the keyboard device of the present invention has the following advantages: ■ All n memory circuits corresponding to students in a class are "1" or all "1";
Since it is equipped with a preset key that presets to 0 to 91, the preset key and the score of students 1 to n will be set to ``O'' or 11 for each booth of a test or practice problem. When only the set key corresponding to 1 +1 is pressed and the start button is pressed, data for n people is generated at once and input into a computer or the like.

As described above, the advantage of the present invention is that when keying n scores for a certain booth, if the score "1" occupies the majority, only the set key corresponding to the score "0" can be pressed. Conversely, if the score ゜O II occupies the majority, the number of keystrokes will be reduced if only the set key corresponding to the score ``1'' is pressed.

By using the keyboard device of the present invention, it is possible to generate data consisting of n pieces of "'1" or "'O" or a mixture of both at once with a much smaller number of keystrokes than conventional key operations, and to input data into an electronic computer. It has the advantage of being able to input data in a shorter time than conventional methods.

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