In the embodiment shown in the figure, the ultraviolet ray sensor is disposed at an appropriate position on the pedometer main body 1 which is easily irradiated with ultraviolet rays. 13 is when the remaining time until the start of sunburn by ultraviolet rays becomes “0”,
Alternatively, it is an alarming unit that outputs an alarm sound, an alarm light, or the like when a predicted time at which sunburn starts is reached.

A large number of input switches are arranged below the display section 5 provided on the pedometer main body 1. Of them, 14 is a reset switch for initializing the microcontroller 3 and the like, and 15 is a reset switch. A mode SW 16 for switching the microcontroller 3 and the like to various modes is an up switch 1 for inputting various numerical information in addition to physical personal information (weight, height, age, gender, waist value, hip value).
7 is down SW, 18 is set SW, 19 is start S
W and 20 indicate graphic switching switches for switching the graphic display unit 6, respectively. Reference numeral 28 in the figure denotes a battery that supplies power to the microcontroller 3 and the like.

In the illustrated embodiment, the walking detecting unit 2 has a pendulum 22 having one end rotatably mounted on a shaft 21,
A magnet 23 attached to the other end of the pendulum 22, a lead SW 24 that can be turned on and off by the magnetic force of a magnet arranged in proximity to the amplitude path of the pendulum 22, a resilient member 25 for returning the pendulum 22 upward, a pendulum An upper stopper 26 and a lower stopper 27 for regulating the amplitude of the pendulum 22 are used. The vibration of the pendulum 22 accompanying the walking is converted into an electric pulse by the reed switch 24, and the pulse is converted into the microcontroller 3 by the reed switch 24. To calculate the number of walks or walking distances, calculate the calorie expenditure from the parameters of the pedestrian's physical personal information and the number of walkings, etc., and display the total number of walkings or walking distances on the display unit 5 such as an LCD. In addition, the calorie consumption and the like can be displayed.

The ultraviolet detecting means 29 includes the ultraviolet sensor 1
2, the amount of ultraviolet light is converted into a photocurrent, the photocurrent is converted into a voltage by the resistor 30, and the obtained voltage is converted into an A / D signal.
The converter 31 converts the data into digital data, and the microcontroller 3 calculates the predicted sunburn start time or the remaining time until sunburn starts based on the digital data, the SPF value, the skin type value, and the unit time, and calculates the result. It is displayed on the display unit 5. That is, since the amount of ultraviolet light received from the ultraviolet sensor 12 is proportional to the current of the resistor R, the amount of ultraviolet light can be determined by measuring the DC voltage across the resistor R.
Since the signal is not processed in, the analog signal is converted into a digital signal via the A / D converter 31 and supplied to the microcontroller 3.

Therefore, if the pedometer main body 1 is set at a position such as a breast pocket where ultraviolet rays can be measured, the intensity of ultraviolet rays can always be accurately measured, and the remaining time until the start of sunburn becomes zero. When the sunburn start time is reached, or when the estimated sunburn start time is reached, the alarm means 13 is driven by a signal output from the microcontroller 3 to emit an alarm sound. In the illustrated embodiment, the warning means 13 is a speaker, but it is a matter of course that vibration or warning light may be emitted instead. In addition, since the ultraviolet intensity can be measured for 24 hours, “ultraviolet intensity versus time” of one day can be displayed on the display unit 5 (FIG. 5).

Even if the pedometer main body 1 is under the clothes of the pedestrian and the ultraviolet sensor 12 does not function, it is possible to measure the predicted sunburn start time or the remaining time until the start of sunburn. In addition to the mode in which the intensity of ultraviolet rays is constantly measured, the intensity of ultraviolet rays may be measured in advance before the start of sunburn prediction, and stored in the storage device in the microcontroller 3.
After the start SW19 is pressed to start the ultraviolet ray measurement, the pedometer body 1 is worn under clothing such as the waist, and an internal timer for a tanning start prediction time or until sunburn starts depending on the presence or absence of a signal from the walking detection unit 2. If the internal timer for the remaining time is turned ON and OFF, the internal timer can be automatically controlled without performing the switch operation, and the alarm means 13 is activated when the estimated sunburn start time or the like is reached. .

The formula for calculating the predicted sunburn start time is as follows. Predicted tanning start time (when detecting UV intensity with sensor during measurement) Predicted tanning start time = K * M * SPF * T * UVP0-
t * (UVP1 + UVP2 + UVP3... UVPn) K: constant obtained by experiment T: allowable time constant in case of reference ultraviolet intensity obtained by experiment t: unit time M: skin type value (skin tanning due to race or individual difference) SPF: Sun care index (Unified Standard of the Japan Cosmetic Industry Association) UVP1-n: Ultraviolet intensity UVP0: Standard ultraviolet intensity Predicted time to start tanning (when ultraviolet intensity is not detected by sensor during measurement) Predicted time to start tanning = K * M * SPF * T * UVP0-
(T1 + t2 + t3... Tn) * UVPa t1 to tn: time during which there is a walking signal (considered as outdoor) UVPa: ultraviolet intensity measured at the start of the expected sunburn start time

Further, the degree of obesity and / or the body type of the user can be displayed using the graphic display section 6 described above. Obesity is weight (Kg) and height (m)
Can be measured from the following information using the following equation. BMI = weight (Kg) / (height (m) * height (m)) BMI (standard) = height (m) * height (m) * 22 Ratio of weight to standard weight (%) and obesity ratio (%) = (BMI / BMI (standard)) * 100
(%) Obesity ratio is shown in Table 1 below.

[Table 1] Also, the body shape is determined by the waist value / hip value, and can be determined according to the following Table 2.
