Operation of Embodiment First, an outline of the overall operation will be described with reference to FIG. In step T1, a standby state (HALT) is entered until a time count process or a key process request is issued. Now, when it is the timing for timing, the process proceeds to the next step T2, the timing processing program is designated, and the timing processing is started. This processing is performed by adding a predetermined unit data to the basic time data stored in the time storage register on the first row of the RAM 16 to obtain the current time, and transferring this to the original time storage register in the RAM 16. Done. Then, in the next step T3, the contents of the J register in the RAM 16 are checked. This J register stores a jogging mode flag. J = 1 is set during jogging measurement, and the jogging process (step T4) described later is executed. However, after the jogging ends, the pulse is restored to the normal pulse rate. J = 2 during the recovery time measurement of
This is detected in 5 and recovery time measurement processing (step T6) described later is executed. Then, the jogging process (step T4) and the recovery time measuring process (step T4)
When step 5) ends, the display process is executed in step T7, and then the process returns to step T1.

When any switch operation is performed, a key processing program corresponding to the switch operation is designated, key processing (step T8) corresponding to the operation switch is executed, and after display processing (step T7), the process returns to step T1. Now, in the jogging mode, if the pace number and the normal pulse rate for jogging are set, after the switch S2 is operated to switch to the set mode, if the pace number is set, the switch S3 and the normal pulse rate are set. If so, the switch SA is operated. Then, the above key processing (step T
According to 8), the pace number of joggins is set in the P register in the RAM 16 according to the number of times the switch S3 is operated, and the normal pulse rate of the user is set in the A register according to the number of times the switch SA is operated. In this way, the switch SA is operated to start jogging after setting various necessary data in advance before jogging. Then, the J in the RAM 16 is operated in accordance with the operation of the switch SA.
The jogging mode flag "1" is set in the register.

FIG. 7 shows the jogging process (step T shown in FIG. 6).
It is a flow chart for explaining the specific contents of 4). This flow is executed along with the start of jogging. First, in step T4-1, it is checked whether 1 second has elapsed after the start of jogging. If 1 second has elapsed since the start of jogging, an increment process (step T4-2) is performed to increment the value of the N1 register (jogging measurement register for measuring a unit of 1 second) in the RAM 16 by 1. As a result, in the next step T4-3, the value of the N1 register becomes "1".
0 ", that is, if 10 seconds have passed since the start of jogging,
At the next step T4-4, the contents of the N1 register are cleared and, at the same time, the N2 register (1
+ The value of the jogging measurement register that measures 0 second unit
Increment processing of 1 is executed. Then, in the next step T4-5, whether one minute has passed after the start of jogging,
That is, it is checked whether the value of the N2 register is "6", and when one minute has passed, the contents of the N2 register are cleared at the next step T4-6, and the N3 register (measurement in units of 1 minute) in the RAM 16 is performed. Increment processing for incrementing the value of the jogging measurement register) by 1 is executed. And RA to show that one minute has passed after the start of jogging
The one-minute elapsed flag "1" is set in the M1 register in M16 (step T4-7). In this way, the values of the jogging measurement registers N1, N2, and N3 are updated at the same time when the jogging is started, and the measurement times of 1 second digit, 10 seconds digit, and 1 minute digit are sequentially obtained, and when 1 minute has elapsed after the jogging start,
The measurement time of the upper digit is obtained in the same manner as described above (step T4-8).

Then, the pulse measurement operation is also executed with the start of jogging, but the following processing is executed according to the pulse measurement. That is, first, it is determined whether the value of the m register, which will be described later, in the RAM 16 is "30" (step T4-9),
If it is less than "30", it is checked whether 1 minute has elapsed according to the contents of the M1 register (step T4-10). Then, T1-11 is executed every one minute after the start of jogging, and the measured pulse rate is X1 to X10 in the RAM 16.
X addressed by the value in one of the registers
1 register. Here, the X1 to X10 registers are registers for storing the pulse measurement value every minute. afterwards,
An increment process (step T4-12) for incrementing the value of the 1 register by 1 is performed, and as a result, it is checked whether the value of the 1 register exceeds "10" (step T4-1).
3). Now, when the pulse rate measured every minute is measured 10 times, the value of 1 register exceeds "10", so that the initialization process of transferring "1" to 1 register (step T4-14). ) Is executed. Then, the pulse rate measured every minute in this way is X1.
~ X10 register sequentially stored, each measured pulse rate for 10 minutes obtained by this, the next step T4-15
so Is calculated to obtain an average value thereof, and the average value obtained for 10 minutes is Z1 in the RAM 16.
~ Of the Z30 registers, stored in the Zm register addressed by the value of the m register. Z1 to Z30
The register is a register for storing the average pulse rate for 10 minutes. Then, the contents of the M10 register in the RAM 16 are checked (step T4-16). This M10 register stores a flag of 10 minutes elapsed, and after every 10 minutes, an increment process of incrementing the value of the m register by +1 is executed in the next step T4-17, and then Z1 to Z30.
The contents of the register are graphically displayed on the dot matrix display 1C (step T4-18). Such a process is repeated until the value of the m register becomes "30", and as a result, the average pulse rate for 10 minutes is successively stored for a maximum of 30 times (5 hours) sequentially in the Z1 to Z30 registers. The contents are displayed as a graph.

FIG. 9 (A) shows a display example at this time. Every time the pulse rate is measured, the display mode is changed to the pulse measurement mode, and the upper digital display 1A displays the date and time of the jogging, The lower digital display 1B displays the measurement time data at the time of pulse measurement, and the dot matrix display 1C further displays the average pulse rate for 30 times as a graph. In this way, since the change in pulse rate is displayed in a graph during jogging, running while checking this can serve as a guide for the pace distribution method, and the physical strength can be efficiently improved.

FIG. 8 shows the recovery time measurement process (step T shown in FIG. 6).
It is a flow chart for explaining the concrete contents of 6). This flow is started when the jogging is stopped, and when the flow is entered, the value of the Tr counter in the RAM 16 is incremented by 1 (step T6-1). This Tr counter is a recovery time measurement counter for measuring the recovery time to the normal pulse rate after jogging is stopped, and this recovery time is displayed on the lower digital display B in step T6-2. Then, "1" is subtracted from the value of the INT counter in the RAM 16 (step T6-3). This IN
The T counter counts the time interval of pulse measurement for executing the measurement operation of the pulse rate every 5 seconds after jogging is stopped. As a result of the subtraction of the content, the next step T6
At -4, it is checked whether or not the value becomes "0",
When it reaches “0”, the INT counter has an initial value of “5 (seconds)”.
Are set (step T6-5). Then, since 5 seconds have elapsed, the pulse rate is measured in the next step T6-6, and this measured value is transferred to the Y register in the RAM 16. The measured pulse rate (value of the Y register) thus obtained is compared with the normal pulse rate of the user preset in the A register of the RAM 16, and the measured value is below the normal pulse rate. Is detected, step T6-7
To T6-8, the value of the CT counter in the RAM 16 is incremented by 1. This CT counter counts the number of times in order to detect that the measured value has fallen below the normal pulse rate twice in succession, and the next step T6-
At 9, it is determined whether the value of the CT counter is "2",
As a result, when the value measured every 5 seconds after the jogging is stopped is lower than the preset normal pulse rate for two consecutive times, that is detected in step T6-9 and the next step T6-10. Then, the value of the CT counter is cleared. Then, after the recovery time measurement end sound flag "1" is set in the SR register in the RAM 16, the recovery time measurement end sound is processed and an end sound is generated from the alarm unit 22 and the recovery time measurement end. Is notified by sound and the contents of the Tr register are displayed, and then the SR register is cleared (steps T6-11, T6-12,
T6-13). Therefore, the Tr counter measures the pulse recovery time up to the moment when the pulse rate measured every 5 seconds after jogging is stopped is lower than the normal pulse rate twice in succession, and this value is shown in FIG. 9 (B). It will be displayed digitally. FIG. 9B shows the display state in the recovery time measurement mode. After stopping jogging like this,
Since the recovery time until returning to the normal pulse is measured and displayed, the degree of improvement in physical strength can be known.

The present invention is not limited to the above embodiments, and various modifications can be applied without departing from the present invention.

[Effects of the Invention] As described in detail above, the pulse rate measured by the pulse rate detection means is equal to or less than the normal pulse rate stored in the pulse rate storage means from the end of jogging or the like. Since the time interval until time is measured and the measured second time interval is displayed, by knowing the displayed time interval, it is possible to accurately and easily determine the degree of improvement in physical strength due to jogging or the like. I can know.
