Abstract

PURPOSE:To attain quickly and accurately consecutive input operation of same data by providing a duplicated depression detecting section and using a value assigned to each key switch depressed duplicatedly to designate the number of consecutive input of the same data. CONSTITUTION:When a key switch, e.g., a numeral key switch, is depressed while another key switch, e.g., a data key switch, is depressed in a key switch group 1, a duplicated depression detecting section 4 detects the duplicated depression of the key switches. Then the detection section 4 informs a value of a numerical key switch to a strobe generating section 3, which generates a strobe signal for a number of times corresponding to the informed value. During this time, the code generating section 2 continues to generate a data code corresponding to the depressed data key switch in advance. Thus, the same data of an optional number are inputted quickly, accurately and continuously depending on the kind of the numerical key switch depressed duplicatedly and the data key switch.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a keyboard, and particularly to a keyboard with an improved continuous input function for the same data.

[Prior Art] When inputting multiple pieces of the same data using a conventional keyboard, instead of pressing the data key switch the required number of times, the same data key switch is input at regular intervals while the data key switch is pressed. A type of keyboard is used that automatically generates data. The Kt diagram shows the configuration of such a conventional keyboard, where l is a data key switch.

A plurality of key switches, that is, a key switch group including numeric key switches, etc., this key switch group l
A code generator generates data codes corresponding to the seven pressed key switches, and J is a strobe signal generator that generates a strobe signal to notify the timing of generation of valid data.

Next, the operation will be explained. The strobe signal generating section 3 detects that any one key switch in the key switch group l is pressed and generates one strobe signal. Furthermore, if the same key switch is held down for a certain period of time or more, the strobe signal generating section J
After the first strobe signal is generated, the strobe signal is continuously generated at regular intervals. At this point, the code generation section.

As long as a key switch is pressed, the data code corresponding to that key switch continues to be output, so by changing the length of time that the same key switch is held down, you can output the same data any number of times in a row. can be entered.

The same data continuous input function of conventional keyboards is performed as described above, but in order to input the same data continuously, the relevant key switch must be held down for a certain period of time, and the input As the number of characters increases, it takes longer to operate, and since the number of characters input is determined by the length of time the key switch is pressed, it is difficult to control accurately.

[Summary of the invention]

This invention has been made to eliminate the above-mentioned drawbacks of the conventional ones, and includes a duplicate press detection section that detects duplicate presses of two key switches, for example, a data key switch and a numeric key switch. , by interpreting the value indicated by the numeric key switch as the number of inputs of the same data,
To provide a keyboard that quickly and accurately performs a concatenated input function for the same data.

[Embodiments of the invention]

Hereinafter, an example #J of the keyboard according to the present invention will be explained with reference to FIG. This embodiment is different from the conventional example shown in FIG. This is because we have established the following.

Next, the operation will be explained. When one key switch in a key switch group, such as a data key switch, is pressed and seven other key switches, such as a numeric key switch, are pressed, the duplicate press detection unit detects the presence of these key switches. Detects repeated presses and strobe generator J
Informs the value of the VC numeric key switch. As a result, the strobe generator 3 generates the strobe signal a number of times corresponding to the notified value. During this time, the code generator will generate the data corresponding to the data key switch that was pressed first.
Since the code continues to be generated, it is possible to continuously input any number of the same data depending on the type of numeric key switch that is pressed repeatedly with the data key switch.

In addition, in the above embodiment, a case was described in which a numeric key switch is used to specify the number of the same data to be input continuously, and the value indicated by the numeric key switch is used as the input number, but the key 2 switch used to specify the number of pieces is Any key switch other than numeric or - switches may be used, and any value for the number of inputs may be assigned to each key switch. In addition.

If a data key switch other than a numeric key switch is used to specify the number of items, the 1 double press detection unit uses the previously pressed key switch for data and the subsequent pressed key pressed while this key switch is being pressed. It is designed to determine that the switch is for specifying the number of pieces.

〔Effect of the invention〕

As described above, according to the present invention, the number of consecutive inputs of the same data is specified not by the continuous press time of the key switch, but by the value assigned to each key switch of "i4 repeated press up". So.

It has the effect of allowing continuous data input operations to be performed quickly (and accurately).
