Next, the operation of the first embodiment will be described with reference to FIGS. 9 and 10 are flowcharts showing the overall operation.

(1) Time display mode (M = 0) Normally, the control unit 14 controls the frequency division / timing signal generation circuit 22
Is kept in the HALT state in step S1 until a clock signal is output from or the key input section 20 receives a key input.

When the clock signal is output, it is determined in step S1 that the clock signal is present, and the flow advances to step S2. In step S2, the current time data stored in the clock register B is updated. In the next step S3, "M = 1, F =
It is determined whether or not the content of the mode register M is "1" and the content of the flag register F is "1". If YES is determined in step S3, the process proceeds to step S4, and if NO, the process proceeds to step S7.

If the time display mode is "M = 0", the judgment is NO, and the process proceeds to step S7. In step S7, it is determined whether "M = 2, F = 1". If YES is determined in this step S7, the process proceeds to a step S8, and if NO, the process proceeds to a step S9. In this case, "M
= 0 ”, the determination is NO, and the process proceeds to step S9.

In the display process of step S9, "M
= 0 ”is determined, and the current time data stored in the clock register B, for example,“ SUN 7-28 ”
10:56 23 (Monday, July 28, 10:56:02
3 seconds) is displayed as shown in FIG. After performing step S9, the process returns to step S1.

(2) Pressure Setting Mode (M = 1) Here, a procedure for adjusting the air pressure in the gas tanks 6, 7 and setting the adjusted pressure data in the memory will be described. In this case, first, the K1 key is input to set “M = 1”, and the pressure setting mode is set. Next, air is injected into the gas tanks 6 and 7 by the air pump, and when the support state is optimal, the K2 key is input to start the pressure measurement.

That is, when the K1 key is input, step S
At 1, it is determined that a key input has been made, and the process proceeds to step S10.
In step S10, it is determined whether the input key is the K1 key. In this case, since the K1 key has been input, “YES” is determined in the step S10, and the process proceeds to the step S11. In step S11, the content of the mode register M is incremented by 1 to "M = 1", and the pressure setting mode is set. After the execution of step S11, the process proceeds to the display processing of step S9.

Next, when the K2 key is input, the process proceeds from step S1 to step S10 in the same manner as described above. In step S10, since the K2 key has been input, the determination is NO, and the process proceeds to step S12.

In step S12, it is determined whether the input key is the K2 key. Now, since the K2 key has been input, it is determined to be YES and the process proceeds to step S13.
In step S13, it is determined whether or not "M = 1". If "YES" is determined in the step S13, the process proceeds to the step S1.
The process proceeds to step S4, and if NO, the process proceeds to step S17. In this case, since “M = 1”, the answer is YES, and step S14 is performed.
Proceed to.

In step S14, it is determined whether or not "F = 0". If YES is determined in this step S14, the process proceeds to step S15, and if NO, the process proceeds to step S16. In this case, since “F = 0”, the determination becomes YES and the process proceeds to step S15.

In step S15, the timer of the register T starts, and "1" is written in the flag register F. Therefore, “M = 1, F = 1”. The process proceeds from step S15 to step S9.

However, when "M = 1, F = 1", YES is obtained in step S3 because "M = 1, F = 1", and the process proceeds to step S4. In step S4, a timer process is performed and the register T is incremented by one. Next step S
At 5, it is determined whether the content of the register T has reached a value corresponding to "5 seconds". In the case of YES in step S5, the process proceeds to step S6, and in the case of NO, step S9
Proceed to.

That is, in the first embodiment, the pressure measurement is performed every 5 seconds, and step S is performed until T = 5 seconds.
Steps 1 to 5 and 9 are repeatedly executed. And the register T
Becomes a value corresponding to "5 seconds", and Y is determined in step S5.
If it is determined to be ES, the process proceeds to step S6.

In step S6, the pressure in the gas tanks 6, 7 is measured by the sensor unit 15, and the obtained pressure data, for example, "2.12 (kg)" is stored in the pressure register D. That is, the control unit 14 includes the sensor unit 15 and the A / D converter 16
To output the operation signal a to operate them. Thereby, the sensor voltage output from the sensor unit 15 is input to the A / D converter 16. Then, the sensor voltage is converted into a digital signal by the A / D converter 16 and input to the control unit 14. The control unit 14 stores the digital signal input from the A / D converter 16 in the pressure register D of the RAM 18. Further, the contents of the register T are cleared. The process proceeds from step S6 to step S9.

In the display processing of step S9, "M = 1"
Is determined, and the pressure data stored in the pressure register D, for example, “2.
12 (kg) "is displayed on the display unit 12. Since the pressure is measured every 5 seconds in this manner, the gas tanks 6 and 7 are set to the optimum pressure during that time.

To end the pressure setting, when the K2 key is input again, the answer in step S14 is NO and the process proceeds to step S16, where the timer by the register T is stopped, and "0" is written in the flag register F. Therefore, “M = 1, F = 0”. The process proceeds from step S16 to step S9.

(3) Stopwatch Mode (M = 2) Next, the operation of storing the temperature inside the shoe together with the elapsed time (lap time) during exercise such as jogging will be described. In this case, the K1 key is input, and the content of the mode register M is incremented by 1 in step S11 to set "M = 2" to set the stopwatch mode. Next, the K2 key is input to start stopwatch measurement.

When the K2 key is input, the process proceeds from step S1 to step S10, as described above, and proceeds to step S10.
Then, since the K2 key has been input, the determination is NO, and the process proceeds to step S12. In step S12, YES is determined by inputting the K2 key, and the flow advances to step S13.

In step S13, it is determined whether or not "M = 1". Since "M = 2", the determination is NO and the process proceeds to step S17. In step S17, it is determined whether or not “M = 2”. In this case, since "M = 2", YES
It proceeds to step S18. In step S18, it is determined whether or not “F = 0”. This step S18
If YES is determined in step S20, the process proceeds to step S19, and if NO, the process proceeds to step S20. In this case, since “F = 0”, the determination becomes YES and the process proceeds to step S19.

In step S19, the pressure data stored in the pressure register D, for example, "2.12 (kg)" is transferred to the pressure data area of the data memory 18a.
Stopwatch measurement starts and flag register F
"1" is written to. Therefore, "M = 2, F = 1"
Becomes The process proceeds from step S19 to step S9.

Thereafter, every time the clock signal is output, the process proceeds from step S1 to steps S2 and S3. In step S3, since "M = 2, F = 1", it is determined as NO, and the process proceeds to step S7. In step S7, “M = 2, F
= 1 ”, the determination is YES, and the process proceeds to step S8.
In step S8, the stopwatch register C
Is updated by +1 and the elapsed time is measured. In the display process of step S9, the stopwatch mode of “M = 2, F = 1” is determined, and the elapsed time data stored in the stopwatch register C is displayed on the display unit 12. After performing step S9, the process returns to step S1.

Next, to store the temperature inside the shoe during exercise, the K3 key is input. When the K3 key is pressed, as described above, steps S1 to S10 are executed.
And NO is determined in each of steps S10 and S12, and the flow proceeds to step S21. In step S21, it is determined whether the input key is the K3 key. In this case, K
Since the 3 key has been input, YES is determined in the step S21, and the process proceeds to a step S22.

In step S22, it is determined whether "M = 2". In this case, since “M = 2”, the determination is YES, and the process proceeds to step S23. In step S23, it is determined whether or not "F = 1". If YES is determined in this step S23, the process proceeds to step S24, and if NO, the process proceeds to step S9. In this case, since “F = 1”, the determination becomes YES and the process proceeds to step S24.

In step S24, the elapsed time data measured by the stopwatch register C, for example, "00:
2500 (25 minutes) "is stored in the wrap memory area Y of the data memory 18a. In step S25, the temperature inside the shoe is measured by the temperature sensor 10, and the measured temperature data, for example, “37.2 (° C.)” is stored in the temperature memory area Z of the data memory 18a. From step S25, the process proceeds to step S9.

In the display process of step S9, "M = 2"
Is determined, and as shown in FIG. 11 (C), the pressure data “2.12
(kg) "and the elapsed time data" 0 "in the lap memory area Y
0: 2500 ”and the temperature data“ 37.2 ° C. (° C.) ”of the temperature memory area Z are displayed on the display unit 12.

Similarly, every time the K3 key is input, the temperature inside the shoe is stored together with the lap time. When the K3 key is input 1 hour and 15 minutes after the start of measurement, FIG.
As shown in (D), the pressure data “2.12 (kg)” in the pressure memory area X, the elapsed time data “01: 1500” in the lap memory area Y, and the temperature data “37.8” in the temperature memory area Z. “(° C.)” is displayed on the display unit 12.

In this case, the K1 key is input, and the content of the mode register M is incremented by 1 in step S11, and "M =
3 "to enter the recall mode. Next, the display switching is designated by inputting the K3 key.

When the K3 key is input, the process proceeds from step S1 to step S10, and NO in steps S10 and S12.
And the process proceeds to step S21. In step S21, since the K3 key is input, it is determined to be YES, and the process proceeds to step S22.

In step S22, since "M = 3", the answer is NO, and the process proceeds to step S26. Step S2
At 6, it is determined whether or not “M = 3”, and the result is YES, and the process proceeds to step S27. In step S27, the data of the pressure, elapsed time, and temperature in the data memories 18a, 18b,... Selected by the register P are designated and transferred to the display register A, and the process proceeds to step S9. In this case, for example, assuming that the data memory 18a is selected, as shown in FIG. 12A, the pressure data “2.12 (kg)” in the pressure memory area X stored first in the data memory 18a, The elapsed time data “00:10 00” in the lap memory area Y and the temperature data “35.6 ° (° C.)” in the temperature memory area Z are displayed on the display unit 12.

Here, when the K3 key is input, step S27 is executed in the same manner as described above, and the next data in the data memory 18a is designated. Accordingly, as shown in FIG. 12B, the pressure data “2.12 (kg)” in the pressure memory area X and the elapsed time data “00: 200” in the lap memory area Y are stored next to the data memory 18a.
0 ”and the temperature data“ 36.0 ° C. (° C.) ”of the temperature memory area Z are displayed on the display unit 12.

Here, when displaying the data stored in the other data memory 18b, the user selects the memory by inputting the K4 key.

When the K4 key is input, steps S1, S
The process proceeds to 10, S12, and S21, and is NO in step S21.
It proceeds to step S28. In step S28, it is determined whether the input key is a K4 key. If YES in step S28, the process proceeds to step S29, and if NO (that is, another key), the process proceeds to step S29.
The process proceeds to other key processes of No.

In this case, since the K4 key has been input, "YES" is determined in the step S28, and the process proceeds to a step S29. In step S29, it is determined whether or not “M = 2 or 3”. Since “M = 3”, the result is YES, and the process proceeds to step S30. In step S30, the contents of the register P are updated, and the next data memory 18b is selected from the data memories 18a, 18b,. The process proceeds from step S30 to step S9.

As a result, as shown in FIG. 13A, the pressure data “1.90 (kg)” in the pressure memory area X and the elapsed time data “lap time area Y” in the lap memory area Y are stored first in the data memory 18b. 00:10 00 ”and the temperature data“ 35.5 ° C.
