Abstract

PURPOSE:To inform only a person who has done switch operation that the operation input is sensed. CONSTITUTION:A switch input sensing part 3 senses that a switch contact 2 is turned on or off from a switch operation part. An electric stimulance impressing part such as a static electricity generating part 4 or a voltage impression part 5 releases static electricity to a finger tip 7 in conformity to a sensing signal given by the switch input sensing part 3 or impresses a voltage directly to the finger tip 7 using a pair of electrodes 6 to allow a current to flow.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation switch for turning on / off a switch when a person touches or approaches a part of a human body such as a fingertip to a switch operation portion.

[0002]

2. Description of the Related Art Conventionally, in the case of an operation switch in which a person touches a part of a human body such as a fingertip with a switch operation part to mechanically turn on and off, the switch operator has surely turned on and off the switch. In order to inform the user, the tension of the contact material is used to give a click feeling during operation.

However, if the operation time of the switch is short, even if there is a click feeling, the input signal of the switch is judged to be noise and the input signal is ignored due to the processing in the part which judges the input of the switch.
In some cases, the input signal could not be detected because the processing could not follow.

Further, recently, with the advent of membrane switches, touch switches, non-contact switches, etc., a buzzer sound and a display lamp are lit to confirm an operation input for a touch feeling which has disappeared. Some of them also notify that an input operation has been performed.

[0005]

However, when the buzzer sound is used, there is a problem that even a person other than the switch operator may hear the buzzer sound, which is annoying and annoying, and the display lamp is lit up. To inform
It is necessary for the switch operator to look at the display lamp, and there is a problem in that the operation input cannot be confirmed when operating at high speed like a computer keyboard or when performing blind touch.

The present invention has been made in view of the above points, and an object thereof is an operation capable of reliably notifying only a person who has performed a switch operation that an operation input has been detected. To provide a switch.

[0007]

According to the present invention, there is provided a switch input detecting section for detecting ON / OFF of a switch contact in an operation switch for turning on / off the switch contact by operating the switch operating section with a fingertip, and a switch input detecting section. And an electrical stimulation applying section that applies electrical stimulation to the fingertip in accordance with the detection signal of 1.

Further, the electric stimulus applying section is a static electricity generating section for generating static electricity.

The electrical stimulus applying section is a voltage applying section for directly applying a voltage to the fingertip.

[0010]

In the operation switch of the present invention, the switch input detection unit detects that the switch contact is turned on and off by the operation of the switch operation unit, and the electrical stimulus application unit such as the static electricity generation unit and the voltage application unit detects the switch contact. The static electricity is discharged to the fingertip according to the detection signal from the switch input detection unit, or a voltage is directly applied to the fingertip by a pair of electrodes to flow a current.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic block diagram showing an embodiment of the present invention. Reference numeral 1 denotes a switch operation section, which is used when a person who operates the switch operates a part (finger) 7 of his / her body.
The switch contact 2 is turned on and off.

In the switch operating portion 1, even if the switch contact 2 is turned on / off by a mechanical operation such as a slide switch, the switch contact 2 is turned on / off by an electric action like a non-contact switch. It may be one.

Reference numeral 3 denotes a switch input detection unit which detects ON / OFF of the switch contact 2 and outputs a detection signal.

Reference numeral 4 denotes a static electricity generating portion, which generates static electricity in response to a detection signal from the switch input detecting portion 3 and discharges the static electricity to the finger 7 of the switch operator.

The static electricity generating section 4 has a high voltage generating section 41, a charge charging section 42 and a discharge electrode 43. The high voltage generating section 41 generates a high voltage and the charge charging section 42 accumulates charges. Then, when a certain voltage is reached, the electric charge is discharged from the discharge electrode 43 to the finger 7 of the switch operator.

Therefore, the switch operator operates the switch through the switch operating unit 1, and when the switch contact 2 is turned on and off, the static electricity is discharged to his / her finger 7, so that the operation input by the switch operation is sure. Only when the switch input is detected, the user can recognize the switch input by the touch of the finger 7.

FIG. 2 is a schematic block diagram showing another embodiment of the present invention. This embodiment is the same as the embodiment shown in FIG.
Instead of the static electricity generating section, a voltage applying section 5 and an electrode 6 are provided.

In response to a detection signal from the switch input detection section 3, the voltage application section 5 applies a voltage between the pair of electrodes 6 built in the switch operation section 1, and the finger 7 touching the switch operation section 7 is used. A current flows, whereby the switch operator recognizes that the switch operation input has been reliably detected.

The present invention is not limited to the operation detecting means of the operation switch and the number of switches.

[0021]

As described above, according to the operation switch of the present invention, the switch input detection unit detects that the switch contact is turned on and off by the operation of the switch operation unit, and the static electricity generation unit, the voltage application unit, and the like are detected. In the electrical stimulus applying section, the operation input is detected by discharging static electricity to the fingertip by the detection signal from the switch input detecting section or directly applying a voltage to the fingertip with a pair of electrodes and applying a current to the fingertip. It was possible to provide an operation switch that can surely inform only the person who performed the switch operation.
