DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable device with a built-in ultraviolet sensor having a central processing unit, a memory, and a display device, and more particularly to a display of a numerical value of the quantity of ultraviolet light having a built-in ultraviolet sensor.

[0002]

2. Description of the Related Art In recent years, an increase in the amount of ultraviolet rays due to the progress of depletion of the ozone layer has raised concerns about the effects on the skin. It is desired. Information on the amount of ultraviolet light can be obtained from weather forecasts, reports of ultraviolet light amount measurement (forecast) by region, and the like. However, it is well known that even in the same area, the amount of ultraviolet light greatly differs depending on whether it is in the shade of a tree, in the sun, or due to a difference in the altitude of the sun. Since the above-mentioned information source of the amount of ultraviolet light has an unspecified number as its destination, even if the area is divided a little, the typical numerical value of a certain point in each area at a certain time is shown as a guide. Target,
It was virtually impossible to obtain specific information over time.

[0003] Further, since such information cannot be obtained without going through a television or the Internet, it is difficult to obtain the information on the go. In addition, actual opening 01
No. 030491 discloses an electronic timepiece with an ultraviolet ray measuring function. This is an ultraviolet sensor 10 that measures ultraviolet light.
5. It is provided with a measuring means comprising the amplifier 106 and the A / D converter 107 and the like, and a timer means comprising a time measuring instrument 113 and the like for starting the measurement of the measuring time of the ultraviolet ray according to the instruction of the starting means. The display unit 104 switches and displays the measured ultraviolet data and the measurement time measured by the timer means via the drive DR1 and the drive DR2.

[0004]

In the electronic timepiece with the ultraviolet ray measuring function having the above-mentioned structure, it is possible to measure the quantity of the ultraviolet ray individually and specifically according to the measuring place.
However, such an electronic timepiece with an ultraviolet ray measuring function only switches and displays a normal time, an ultraviolet ray measuring time and an ultraviolet ray amount, and it is necessary to know in advance that it does not have any knowledge of what it means. We cannot take appropriate measures. In addition, the amount of ultraviolet light increases in proportion to the measurement time, and when the specified value is reached, a warning is given by a buzzer or the like, and even if any measures are taken, the amount of ultraviolet light increases during that time. It can be too late to follow and adapt to the situation.

The present invention has been made in view of such a point, and an object of the present invention is to provide a portable device with a built-in ultraviolet sensor which can promptly obtain information on the amount of ultraviolet light and provide a guideline for appropriate measures against ultraviolet light. is there.

When the power is turned on, the ultraviolet sensor unit 4 operates, and outputs analog data indicating the amount of ultraviolet light to the analog / digital conversion unit 5. The analog / digital conversion unit 5 includes the ultraviolet sensor unit 4
Analog data indicating the amount of ultraviolet light from the camera is converted into digital numerical data as needed. Next, when a data output request is sent from the central processing unit 8 to the communication unit 6, the communication unit 6 receives digital data indicating the amount of ultraviolet light from the analog / digital conversion unit 5 and outputs the digital data to the central processing unit 8. The digital data indicating the amount of ultraviolet light input from the communication unit 6 in the central processing unit 8 is digitized again by the program, and the display device 1
, The ultraviolet light quantity data is displayed on the display device. When the keypad 3 terminates the ultraviolet data display function, a signal is sent from the central processing unit 8 to the power controller 7, and the power controller 7 controls the ultraviolet sensor 4, the analog / digital converter 5, and the communication unit. The power of 6 goes down.

Further, there are stored the effects on the skin and the optimal protective measures corresponding to the numerical data of the amount of ultraviolet light. First, the user selects the display of the influence on the skin or the defense against the ultraviolet light amount displayed by the key input unit 3. The central processing unit 8 reads from the memory 2 the effect on the skin corresponding to the numerical value of the ultraviolet light amount data displayed on the display device 1 and the optimal defense measure, and outputs the readout data to the display device 1 to convert the data into ultraviolet light amount data. The corresponding effect on the skin and the protective measures are displayed on the display device 1. By knowing the amount of ultraviolet light, the user of the device of the present invention can immediately take measures to protect the skin.

Further, by having the power supply control unit 7, power consumption can be reduced. In the present embodiment, the power supply control unit is provided to reduce power consumption. However, if necessary, ultraviolet light amount data that changes every moment may be displayed without performing power supply control. In addition, instead of digitizing the amount of ultraviolet light, it may be displayed using an illustration in order to more easily grasp the situation. Further, the portable device does not need to always touch a part of the body of the user, and may be carried by the user like a mobile phone, and may be capable of appropriately checking the amount of ultraviolet light.
