Abstract

PURPOSE:To improve the reliability in the operation of a touch switch along with a lower power consumption by turning ON or OFF a touch switch mechanism according to the operation of a switch while the inputs by simultaneous operation of a plurality of the touch switches are nullified to generate an alarm. CONSTITUTION:When a switch 6 is turned ON, transistors 10, 12, 16 and 17 are controlled by a high level output through FFs 21 and 22 and a low level output via an inverter 26 so that the input with switches 7 and 8 through a touch switch and comparators 3a and 7 and 3b and 8 is validated to form switch signals SW1 and SW2. Therefore, when the switches 3a and 3b are not used, the switch 6 is turned OFF to prevent useless power consumption. On the other hand, when the switches 3a and 3b are operated simultaneously by mistake, AND gates 24 and 25 are closed by a low level output through an AND gate 15 and an inverter 18 to generate no erroneous signals SW1 and SW2 while an alarms is generated from a speaker through a sound generation circuit 19. In this manner, the reliability in the operation of the touch switch can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is equipped with a touch electrode, and when a part of the human body is touched, the switch II*I! The present invention relates to an electronic wristwatch equipped with a KIIIt2 running touch switch keyaki structure.

Conventional electronic watches equipped with touch switches *S+ often operate without the operator's knowledge if conductive deposits such as water or seawater get on the glass that forms the touch electrodes. Ta.

In this case, if there is a leak after a long period of time, the life of the battery will be shortened. A mechanical switch is used as this safety device.
Its use as an OOK button is well known.

However, in this case, if the Kt1 operator touches the set number of touch lights SKg#, priority will be given to optical input, and the clock operation that the operator intends will not be performed accurately. Even if the operator made a mistake, the product would not stick properly, and there were concerns about its operability.

Even when a LOCK button is provided and touch input is prohibited, the detection circuit remains in constant operation, resulting in a shortened battery life.

The present invention eliminates such drawbacks, and ignores inputs that are input to multiple touch electrodes at the same time when an operator performs an operation or when conductive deposits are attached to the glass surface. I issue a warning! Using 11*11 and the control switch, the operator can arbitrarily touch the manual control to ON5? FiO
The touch input device $1 is equipped with a power switch function that turns off the detection circuit when it is OFF, which greatly increases the reliability of touch switch operation and reduces current consumption. The purpose of this invention is to obtain an electronic wristwatch that can also display various functions.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
