The pressure sensor 18 is electrically connected to the circuit board 13 by a lead wire 19. Further, a battery 20 is disposed inside the device case 10a, and supplies power to the LSI 15.

In this case, the inside of the equipment case 10a is shown in FIG.
As shown in the figure, the atmospheric pressure is applied through a key hole 10c that movably holds the measurement start switch K2. FIG. 7 is a sectional view showing details of the key hole 10c.

The SW (switch) input unit 27 includes the power switch K1 and the measurement start switch K2 shown in FIG. 5, and outputs an operation signal corresponding to the switch operation to the control circuit 2.
Output to 2. The display circuit 28 corresponds to the display unit 1 shown in FIG.
1 is displayed on the display unit 11 in accordance with the display data output from the control circuit 22.

With pedometer mode signal l ₁ is inputted from 2, to the other input terminal 11 from the timing circuit (not shown)

The output of the OR gate OR is a sensor drive signal l ₃ shown in FIG. 11, is input to the control input terminal of the operational amplifier OP5.

The operational amplifier OP5 supplies a drive voltage to the pressure sensor 18, and a reference voltage Vref2 is input to a (+) terminal. This reference voltage Vref2 is the rated voltage V
This is a voltage obtained by dividing cc by the resistors R8 and R9 and connecting the resistors R8 and R9. (-) Of operational amplifier OP5
The terminal is connected to the terminal A of the pressure sensor 18, and the output of the operational amplifier OP5 is connected to the terminal B of the pressure sensor 18.
That is, only when the sensor drive signal l ₃ is at the “H” level,
The driving voltage is output from the operational amplifier OP5, and the pressure sensor 18 operates.

FIG. 10 is a circuit diagram showing details of the amplifier circuit 24. The pressure sensor 1 is connected to the (+) terminal of the operational amplifier OP1.

5 and the counting circuit 26.

Next, the operation of the above embodiment will be described. In the above embodiment, when the pressure measuring device 10 is not used,
The measurement start switch K2 is held at the position shown in FIG. In this state, the pressing portion 1 of the measurement start switch K2
The key hole 10c is hermetically sealed by the O-ring 21 provided in the device 6, and the device case 10a is hermetically sealed from the atmosphere to have a waterproof structure.

When the pressure measuring device 10 is used, a measurement start switch K2 provided on the equipment case 10a is operated. As a result, the O-ring 21 moves to the position 21b after the operation as shown in FIG.
Atmospheric pressure is applied to the inside of the device case 10a via the line d. Therefore, the pressure sensor case 17 is
a, the atmospheric pressure is also applied to the pressure sensor 18 in the pressure sensor case 17, and the pressure in the gas tanks 6, 7 can be measured through the air pipe 12. Become.

When the measurement start switch K2 is operated, the movable contact 13a comes into contact with the fixed contact 13b to turn on the switch, and the SW input unit 27 outputs an operation signal to the control circuit 22. Thereby, control circuit 22 performs an operation according to the mode.

(1) Monitor Mode In the monitor mode in which the pressure in the gas tanks 6, 7 is measured by the pressure sensor 18, the pressure sensor 18 is constantly driven in order to accurately measure the pressure.

Therefore, in the monitor mode, the control circuit 2
2, as shown in FIG. 11, "H" monitor mode signal l ₀ level is output to the drive circuit 23, "L" and outputs a pedometer mode signal l ₁ levels in the driving circuit 23 and the amplifier circuit 24. That is, the monitor mode signal l ₀ of "H" level to the other input terminal of the driving circuit 23 an OR gate OR is input.

[0032] Therefore, as shown in FIG. 11 when the monitor mode signal l ₀ is "H" level, the OR gate OR is output always "H" level of the sensor drive signal l _3,
The signal is input to the control input terminal of the operational amplifier OP5. At this time, the AND gate AND is closed, and the AND gate A
Duty Pulse l ₂ is not output from the ND. As a result, the operational amplifier OP5 constantly outputs a drive voltage to the terminals A and B of the pressure sensor 18, and the pressure sensor 18 is continuously driven.

Further, since the pedometer mode signal l ₁ is "L" level in the amplifier circuit 24, the transistor TR is closed. Therefore, the resistor R1b is not connected between the (-) terminal of the operational amplifier OP1 and the (-) terminal of the operational amplifier OP2, and only the resistor R1a is connected. In this case, the amplification factors of the operational amplifiers OP1 and OP2 are Δ (R2 +
R3) / R1a｝ +1, and the amplification factor is larger than that in the case where the resistor R1b is connected.

Therefore, the output voltages output from the terminals C and D of the pressure sensor 18 are amplified by the operational amplifiers OP1 and OP2, and further amplified by the operational amplifier OP3 to obtain an amplified voltage Vout as an A / D conversion circuit 25 and a counting circuit section. 26. The A / D conversion circuit 25 A / D converts the output voltage from the amplification circuit 24 and outputs it to the control circuit 22. Based on this, the control circuit 22 generates pressure data and outputs it to the display circuit. Thereby, the display unit 1
In 1, pressure data indicating the pressure of the gas tanks 6 and 7 is displayed.

(2) Pedometer mode In the pedometer mode, the gas tank 6,
The number of steps is counted by catching a peak at which the pressure of 7 temporarily increases. In the pedometer mode, the pressure measuring device 10 is used continuously for a long time, so that the pressure sensor 18 is intermittently driven to reduce power consumption, and since the pressure data is larger than usual, the amplification factor of the amplifier circuit 24 is reduced. doing.

Therefore, in the case of the pedometer mode, the control circuit 2
2, as shown in FIG. 11, "H" pedometer mode signal l ₁ level output to the drive circuit 23 and the amplification circuit 24,
An “L” level monitor mode signal ₁₀ is output to the drive circuit 23. That is, in the drive circuit 23, the AND gate AND
The pedometer mode signal l ₁ at the “H” level is input to one input terminal of the pedometer. As a result, the AND gate AND opens,
Duty Pulse l ₂ from the AND gate AND is output and input to the OR gate OR.

[0037] Thus, from the OR gate OR, as shown in FIG. 11, intermittent sensor drive signal l ₃ corresponding to the Duty Pulse l ₂ is output and input to the control input terminal of the operational amplifier OP5. As a result, the operational amplifier OP5 outputs the drive voltage intermittently to the terminals A and B of the pressure sensor 18, so that the pressure sensor 18 is driven intermittently. in this case,
Power consumption by the drive circuit 23 is reduced.

Further, since the pedometer mode signal l ₁ is "H" level in the amplifier circuit 24, the transistor TR is open. Therefore, the resistor R1a and the resistor R1b are connected in parallel between the (-) terminal of the operational amplifier OP1 and the (-) terminal of the operational amplifier OP2. In this case, the operational amplifier OP
1 and the amplification factor of the operational amplifier OP2 are ｛(R2 + R3)
/ R1a + R1b｝ +1, and the amplification factor is smaller than when the resistor R1b is not connected.

Accordingly, the measurement voltages input from the terminals C and D of the pressure sensor 18 are amplified by the operational amplifiers OP1 and OP2, further amplified by the operational amplifier OP3, and converted into an amplified voltage Vout as an A / D converter 25 and a counting circuit. 26.

When the output voltage of the pressure sensor 18 output from the amplifier circuit 24, that is, the pressure data is equal to or higher than a certain level, the counting circuit 26 counts this as one step of walking and controls the counted step number data. Output to the circuit 22. The control circuit 22 outputs display data based on the step count data to the display circuit 28, and the display unit 11 displays the step count data.

In addition, the present invention can be applied to various shoes such as athletic shoes, leather shoes, ski shoes, golf shoes, and various boots, in addition to ordinary shoes. Further, in the above embodiment, only one shoe was described, but the other shoe may be provided with only the gas tanks 6 and 7 and set at the same pressure.
