JP2004007334A - Back light (dial signal lamp) operation function of electronic apparatus using vibration sensor or the like - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To light a back light by shaking a main body (without operating a switch and the like by a finger through a sensor) in an electronic apparatus such as a portable telephone set and a wrist watch. <P>SOLUTION: A vibration sensor 6 (or 10 and 16) is incorporated in the main body 4 (or 9 and 14). The sensor 6 (or 10 and 16) detects vibration by shaking the main body and the back light (indicator panel signal lamp and ten key lamp) is lighted. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a function and a product that can easily turn on a backlight using a detection method such as a vibration sensor.
[0002]
[Prior art]
In the conventional backlight function, a dedicated switch or the like must be artificially operated (contact operation).
[0003]
[Problems to be solved by the present invention]
The conventional backlight function has a problem that it is difficult to operate a switch in a dark place. For example, in the case of a mobile phone, not only is it difficult to operate the switch, but also the location of the switch is difficult to understand, causing an erroneous operation. In the case of a wristwatch, not only is it difficult to operate the switch but also the hand on the opposite side of the watch. There is a problem that the light cannot be turned on when it is occupied.
[0004]
An object of the present invention is to enable a backlight operation function to be activated by a vibration detection sensor or the like built in the product and to easily light the product even in a dark place by shaking the product.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, in the backlight operating function of the present invention, a sensor for detecting vibration or the like is incorporated in the product, and the backlight is operated.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Embodiments of the present invention will be described based on examples with reference to the drawings.
In FIG. 1, a vibration sensor 6 is mounted inside a mobile phone 4.
In FIG. 2, a vibration sensor 10 is mounted inside a wristwatch body 9.
In FIG. 3, a vibration sensor 15 is mounted inside a wristwatch body 14.
[0007]
【Example】
2. Description of the Related Art When a mobile phone is used in a dark place such as a night road, the operation switch backlight and the display panel backlight are turned on by shaking the device once.
Similarly, in a wristwatch, when you want to read the time on a wristwatch in a dark place such as a night road, and when your other hand is occupied by luggage, etc., you can shake the wristwatch arm once to turn on the dial illumination lamp. Can be easily read.
[0008]
【The invention's effect】
The present invention provides a built-in vibration sensor that shakes the product once even in a dark place (more than a certain vibration force that does not operate in daily life operation), turns on the backlight, and achieves proper use without erroneous operation. Can be.

Claims (7)

A function to activate and turn on a backlight (irradiation lamp such as a dial) in a detection method using a vibration sensor or the like in an electronic device used in a dark place such as a mobile phone and a wristwatch. In mobile phones, a function that the vibration sensor detects when the body is shaken and the backlight is activated. In a wristwatch, a function that the vibration sensor detects when the body is shaken in a dark place and the backlight is activated and turned on. In a wristwatch, both a digital system and an analog system are targeted. Operation detection method using vibration sensor, pendulum sensor, etc. for function operation detection. The lighting operation time of the backlight lighting function can be arbitrarily set. Regarding the adjustment of the lighting operation sensitivity of the backlight lighting function, since the life style differs depending on the user, the intensity of the operation sensitivity can be arbitrarily set.
