Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a push button device having a plurality of independent push buttons (keys) arranged in a matrix or in a row, and in particular, a push button device that can operate a push button while checking for erroneous presses without looking at the push button to be operated. For example, push-button devices for electronic devices such as calculators, push-button devices for electronic devices for visually impaired people, and equipment control equipment in factories where incorrectly pressing a switch may lead to an accident. The present invention relates to a push button device that can be used as a push button device, etc.

BACKGROUND ART FIGS. 1 and 2 show a conventional push button device. The configuration of this conventional example will be explained below.
In FIGS. 1 and 2, 1 is a push button, and a plurality of push buttons 1 constitute a push button device. Above push button 1
The relationship between the switch 2 and the corresponding switch 2 is as shown in FIG. 2, and when the push button 1 is pressed in the direction of the arrow, the switch 2 is turned on as shown in FIG.

When the switch 2 is turned on, the state is transmitted to the calculation circuit 3, for example. On the other hand, if a display element or buzzer 4 is provided, the switch operation can be confirmed by the display element or buzzer 4.

Problems to be Solved by the Invention However, in the conventional example described above, if a push button other than the push button that was originally intended to be pushed is pressed, a reset command must be issued to the calculation circuit 3.
For example, if you should have pressed push button A and then push button B, but instead press push button C, reset the information on push buttons A and C that was input to the calculation circuit 3, and then press buttons A and B. You have to press again.

The present invention solves the problems of the conventional example described above, and before giving calculation input to the calculation circuit 3 etc.,
To provide a push button device with a simple configuration that allows auditory, visual, or audiovisual confirmation of which push button has been pressed.

Means for Solving the Problems In order to achieve the above object, the present invention includes a plurality of push buttons and a first switch that sequentially outputs a key input confirmation signal and a key input signal by pressing the push button once. , a second switch, means for confirming an operated push button using a key input confirmation signal output from the first switch before outputting the key input signal; The invention is characterized by comprising means for performing arithmetic processing based on key input signals.

Function The present invention has the above-described configuration, and when a push button is pressed, the first switch is first turned on and a key input confirmation signal is output, and this key input confirmation signal causes confirmation means such as sound generation means to It is possible to confirm which push button was operated, and if it is confirmed that the push button that should be operated has been operated, when that push button is further pressed, the second switch is turned on.
The original key input signal is output, and this key input signal is input to an arithmetic processing means or the like to perform an operation.

Embodiment An embodiment of the present invention will be described below with reference to FIG. In Figure 3, 11 to 13, 21
23 are push buttons and switches corresponding to 1 and 2 in FIG. It is urged in the direction of being pushed up. 51 to 53 are protrusions provided on the push button shafts 31 to 33, respectively;
53 is for controlling switches 61-63. The switch pieces that make up the switches 61, 62, and 63 are made of a flexible material, whereas the switch pieces that make up the switches 21, 22, and 23 are made of a hard material. For this reason,
When push buttons 11, 12, 13 are pressed with normal force, switches 61, 62, 63 are turned on, but switches 21, 22, 23 are not turned on. here,
If you press the push button even harder, switches 21, 22,
23 is also turned on. Reference numerals 71 to 73 are time circuits made of one-shot multis and the like and which make the on-time of the switches 61 to 63 constant; reference numeral 80 is a reproduction means that records a plurality of sounds in advance and reproduces a predetermined sound based on a command to be reproduced. and this reproducing means 8
0 is equipped with a plurality of playback command terminals a, b...z, and if there is an input to terminal a, "JYUUICH (11)" will be played from the speaker 81, and if there is an input to terminal B, "JIYUUICH (11)" will be played back. 12)” is played. 82 is a drive circuit that has a plurality of input terminals like the reproduction means 80, and causes the display 83 to display information in response to input from the terminals.

In FIG. 3, when push button 11 is pressed lightly, only switch 61 is turned on. Along with this, the information of the switch 61 is added to the reproduction means 80 through the time circuit 71, so that the reproduction means 80 reproduces "11" and the speaker 81 outputs the sound "JIYUICHI(11)". If the push button 11 is pressed more forcefully, the switch 21 is turned on, and this switching signal becomes key input information to the calculation circuit 3. In this case, if the reproduced sound from the speaker 81 is "JYUNI (12)", it is known that the push button was pressed incorrectly, and at that stage, the push button should be stopped and the original push button 11 should be pushed.

In addition to auditory confirmation using the speaker 81, if a display 83 is provided, visual confirmation can also be made. Further, the relationship between the push button and the switch is as shown in FIG. 4, where a push button 90 and switch pieces 92 to 94 are provided, and the switch pieces 92 and 93 constitute a switch corresponding to 61 in FIG. 94 may constitute the switch 21.

FIGS. 5A, 5B, and 5C show still another embodiment of the present invention. This embodiment is intended to make the two-stage switching operation of the embodiment shown in FIG. 3 more reliable. In the 5th A, B, C, 3
1a is a small diameter portion formed at the lower part of the push button shaft 31;
b is a spring piece whose one end is fixed to the panel, and the free end of this spring piece 31b is in contact with the side surface of the push button shaft 31.

As shown in FIG. 5A, when the push button 11 is not pressed, both the switch 61 and the switch 21 are off. When the push button 11 is pressed here, the push button shaft 31 moves downward, and as a result, the protrusion 51 of the push button shaft 31 pushes the switch piece of the switch 61, as shown in FIG. However, since the spring piece 31b is engaged with the step between the small diameter portion 31a and the large diameter portion of the push button shaft 31, the push button shaft 31 does not move further downward. If the push button 11 is pressed even more strongly in the state shown in FIG. For this reason,
As shown in FIG. 5C, the switch 21 is also turned on by the lower end of the push button shaft 31.

Effects of the Invention The present invention has the above-mentioned configuration, and includes first and second switches that sequentially output a key input confirmation signal and a key input signal in response to a pressing operation of a push button, and a Since the key input confirmation signal output from the first switch is used to audibly, visually, or audiovisually confirm whether or not a button has been pressed incorrectly, the original key input information is not transmitted to the computing device. Before inputting information, it is possible to check whether or not the button has been pressed incorrectly. Further, the present invention has a structure in which two switches are sequentially turned on by pressing each push button, so that the structure of the push button device is simplified.
