DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pedometer that also serves as a pulse meter, in which a signal from a pulse sensor 1 that measures the pulse and a signal from a step sensor 2 that measures the number of steps are selectively input. A calculation processing unit 3 that performs calculations from the signal to have a pulse measurement function and a step count measurement function is housed in a small case 4, and the case 4
This relates to a pedometer that also serves as a pulse meter and has a changeover switch 5 for selecting a pulse measurement function or a step count measurement function and a display section 6 for displaying the functions on the surface thereof.

In general, there is a growing interest in self-management of health.
An increasing number of people are taking charge of their own health, always paying attention to their health, and taking part in sports and light exercise on their own.

Marathons and jogging have become extremely popular as sports that are light and easy for anyone to exercise.

In this case, you may want to measure your pulse before or after exercising, or to measure how far you ran or walked during a marathon or jogging. When measuring how many steps a person has taken, they used to use separate measuring devices such as a pulse meter or a pedometer.

In this way, in the past, two measuring devices were required: a pulsometer to measure the pulse, and a pedometer to measure the number of steps, and it is still very inconvenient to carry both a pulse meter and a pedometer when jogging. It was extraordinary.

Especially for people in their late 30s and older, it is very important to know their pulse when jogging from a health management perspective. It was hoped that a measuring device with both functions, such as a pulse meter and a pedometer, would emerge.

The present invention has been proposed in view of the above-mentioned points, and it is an object of the present invention to provide a pulse meter/pedometer that has multiple functions such as a pulse meter and a pedometer in one unit.

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

In the figure, 1 is a pulse sensor, and this pulse sensor 1 uses a light emitting diode as a light emitting element and a phototransistor as a light receiving element.

Reference numeral 2 denotes a step count sensor. This step count sensor 2 uses a pendulum supported by a spring, and the pendulum swings each time the user walks, outputting one pulse with each vibration.

Reference numeral 3 denotes an arithmetic processing unit, which uses a crystal oscillator 7 as a reference oscillation, and converts signals from the pulse sensor 1 and step sensor 2 into pulse rate, walking distance, and the like.

Furthermore, since the walking distance differs depending on the person, in order to ensure accuracy when calculating the walking distance, a signal from the walking distance setting switch 8 that adjusts the walking distance is also input to the processing unit 3. .

The arithmetic processing unit 3 also has a stopwatch function, a clock function, and the like.

Reference numeral 5 denotes a changeover switch, and this changeover switch 5 is used to select and switch among the step counting function, stopwatch function, clock function, and the like.

Reference numeral 6 denotes a display section, and this display section 6 displays the calculation results of the various functions described above, and uses a liquid crystal display to reduce power consumption.

Furthermore, as shown in Fig. 2, the display section 6 has a 7-segment display pattern and a pictorial display according to the mode at the time (a colon in the center of AM-PM for a clock, a stop W mark for a stopwatch, and m for a distance). etc.) for easy viewing and sharing.

Reference numeral 4 denotes a case, in which the arithmetic processing section 3 is housed, a display section 6 is arranged approximately in the center of the upper surface of the case 4, and below the display section 6 there are a changeover switch 5 and a start/stop button. 9 and clear button 10 are arranged.

The case 4 itself is large enough to be held in one hand, as shown in Figure 4, and has a width setting switch 8 on one side.
At the same time, a pulse sensor 1 is arranged on the back side, and a concave notch guide 11 is provided when placing a finger on the pulse sensor 1.
The operation of the zero or less embodiment in which .

First, in the pulse measurement function, when a finger is placed on the pulse sensor 1, the pulse sensor 1 detects a fingertip pulse wave, and this signal is amplified and shaped by the amplified waveform shaping circuit 12, and then sent to the counter 13
．． 14 in parallel.

These counters 13 and 14 count at the rising edge of the signal, and are connected to AND circuits 16 and 16 in parallel with the gate 17.
It is input to the divider 15 via T and counters 18, 18.

That is, the input of the AND circuit is synchronized with the reference signal of the reference signal generation circuit 23 whose frequency is divided by the crystal oscillator 7, and is switched depending on whether or not it is preset from the presetter 24 by the switching signal of the switching F/F 20. The counter 18 converts either of the received signals into a BCD code, for example.

Furthermore, the signals from counters 13 and 14 and the signal from counter 18 are divided.

The pulse rate is obtained by dividing a set constant by the count value.

The numerical value is held in the result holding circuit 22 and displayed on the display section 6 via the display switching circuit 21 for selective display.

For example, when the number of steps is displayed and the pulse is measured, the pulse rate is displayed with priority.

Next, when measuring the number of steps, the selector switch 5 is switched to the "1 step count" position.

When walking, vibrations occur each time the user walks, and the pendulum of the step count sensor 2 swings to generate a signal, which is waveform-shaped by the waveform shaping circuit 25 and input to adders 26 and 26, respectively.

One adder 26 adds a constant 1 to count the number of steps, and displays the step number on the display section 6 via the display switching circuit 21.When measuring a distance, set the step distance to the force measuring device 26. The step width value from the switch 8 is added, the calculation is multiplied, and the result is displayed on the display section 6 as described above.

Furthermore, in the case of a clock function or a stopwatch function, the reference signal from the crystal oscillator 7 drives the circuits of the clock timer 27 and stopwatch timer 28 to display the time and time.

Note that the arithmetic processing section 3 based on the input signals from each sensor is made into an IC with a C-MO8 structure using a microcomputer, thereby making it compact and low in power.

The power source is battery-powered.

As described above, the present invention houses an arithmetic processing unit having a pulse measurement function and a step count measurement function in a small case, and includes a changeover switch for selecting the pulse measurement function and the step count measurement function and a display unit for displaying the functions. Because of this, it is possible to have a pulse measurement function and a step count measurement function in one small case.
Therefore, when exercising, such as jogging or running a marathon, it is possible to exercise while constantly monitoring the condition of one's body, which is extremely convenient.
