The time counting circuit 3 counts the clock signal from the frequency dividing circuit 2 to obtain time and date data, and outputs the time and date data to the CPU 5. The stopwatch counting circuit 6 starts counting the 100 Hz signal input through the AND gate 4 when the flip-flop 7 is set by the signal output from the CPU 5, and the flip-flop 7 is reset to supply the 100 Hz signal. Is a circuit that measures the time until the stop of, and outputs the measured stopwatch time to the CPU 5.

The switch section 8 comprises a mode switch (not shown) for switching operation modes, a start / stop switch for stopwatch measurement, a switch for selecting a personal code, a group code, and the like.

The CPU 5 is a central processing unit for detecting the switch input from the switch unit 8, measuring the stopwatch time, displaying the time, etc. In the clock mode described later, the current time is displayed on the display unit 9, and the stopwatch mode is displayed. In, the time is measured from when the start / stop switch is turned on to when it is turned off, and the measured time is stored in the RAM 10. Further, in the data display mode, the average measurement time for each individual and each group is stored in the RAM 10
It is read from and displayed on the display unit 9.

FIG. 2 is a diagram showing a memory configuration of the RAM 10. In the RAM 10, a mode register M for storing a numerical value corresponding to the operation mode, a register I for designating one of a measurement time memory, a personal total memory and a group total memory described later, and a pointer N for designating data to be read, A flag FS indicating whether or not the stopwatch time measurement is started, a measurement time memory TM, a personal total memory PM, and a loop total memory GM are provided.

The measurement time memory TM is a memory for storing the measurement time measured in the stopwatch mode, a memory area for storing the group code and the individual code of the measurement time, a memory area for storing the measurement time, and its measurement. It is composed of a plurality of sets of memories, one set of which is a memory area for storing a rank indicating which time is the number of all the measured times.

The individual total memory PM is a memory for storing the average value and rank of the measurement time for each individual, and has a memory area for storing the individual code, a memory area for storing the number of data, and the measurement time for each individual. It is composed of a plurality of sets of memory, one set including a memory area for storing an average value and a memory area for storing an order for each individual.

The group total memory GM is a memory for storing the average value and order of the measurement time for each group, a memory area for storing the group code and a memory area for storing the number of measurement time data having the group code. And a memory area for storing the average value of the measurement time for each group, and a memory area for storing the order of each group, which are a plurality of sets of memories.

Next, the operation of the embodiment having the above configuration will be described with reference to the flow charts of FIGS. 3 and 4. FIG. 3 is a flowchart showing the overall operation of the embodiment. In step S1 of FIG. 3, it is determined whether or not there is a switch input. If any switch input is being performed, the switch process of step S2 is executed.

FIG. 4 is a detailed flowchart of the switch process. First, it is determined whether or not the mode switch is operated in step S21 of FIG. If the operated switch is the mode switch, the value of the mode register M is incremented to change the value of the register M between "0 and 2" in step S22.

After updating the value of the mode register M, it is determined in step S23 whether or not the mode register M is "2". If M = 2, it means the data read mode,
In this case, in step S24, the measurement time memory TM is set as "0" in the register I to read the data.
Is specified. Then, in step S25, it is determined whether or not the data is stored in the measurement timer memory TM, and when the data is stored, the pointer N is set to "1" in step S26 to designate the data with the first rank. To do.

At this time, if no data is stored in the measurement timer memory TM, the pointer N is set to "0". That is, by operating the mode switch, it is possible to cyclically switch the M = 0 clock mode, the M = 1 stopwatch mode, and the M = 2 data display mode. Further, when the data is stored in the measurement time memory TM when the mode is switched to the data display mode, the data having the first rank in the data is designated and the data is displayed in the display processing described later. It
At this time, if no data is stored, N = 0 is designated and no data is displayed.

If it is not the mode switch that was operated in the determination of step S21, the process proceeds to step S28 and it is determined whether the value of the mode register M is "1". If M = 1, it means stopwatch mode, and in this case, step S
In step 29, it is determined whether the start / stop switch is operated.

If the operated switch is the start / stop switch, the flag FS is set to "0" in the next step S30.
Or not. If FS = 0, the stopwatch measurement has not started, so in step S31 the flip-flop 7 (see FIG. 1) is set to start time measurement, and in step S32 the flag FS is set to "1".
To set.

At this time, if FS = 1, it means that the stopwatch time has started to be measured. Therefore, the process proceeds to step S33, the flip-flop 7 is reset to stop the time measurement, and further the flag F is determined at step S34.
Set "0" to S.

Then, in step S35, the data measured this time is stored in the measurement time memory TM together with the group code and the individual code (described later). Furthermore, step S
At 36, ranking is performed in the data stored in the measurement time memory TM, and the calculated ranking is written in the corresponding area of the measurement time memory TM.

In step S37, the number of data in the memory area of the same personal code as the data measured this time in the personal total memory PM is incremented by 1, and the average value of the measurement time of the individual is calculated.

In the next step S38, the above-mentioned average value is compared with the average value for each individual in the total personal memory PM to calculate the order for each individual, and when the order is changed, the new order is set for the individual total memory PM. Write to the corresponding area of.

Further, in step S39, it is determined whether or not a group code (affiliation code) is set in the data measured this time. If the group code is set, in step S40 the corresponding group code in the group total memory GM. The number of data in 1 is incremented by 1 and the average value of the group is calculated.

Then, in step S41, the above-mentioned average value is compared with the average value of each group of the group total memory GM to perform ranking for each group. Write in the corresponding area.

By these processes, when the stopwatch measurement is performed, the average value of the measurement time for each individual and each group is calculated from the individual code and the group code input by the operation of the individual selection switch described later, Furthermore, the rankings for each individual and each group are calculated from the average value thereof.

Therefore, when the traveling times of a plurality of persons are measured, it is possible to know the average value and the ranking of the times for each individual. Further, it is possible to know the average value and the ranking of the measurement time for each group to which each person belongs.

If it is not the start / stop switch that was operated in the determination of step S29, step S42
Then, it is determined whether or not the individual selection switch is operated. When the individual selection switch is operated, the code is changed between "1 to 20" every time the switch is operated in step S43.

If it is not the individual selection switch that was operated at this time, the process proceeds to the switch processing corresponding to the individual code and group code in step S44, and the individual codes "1 to 20" are changed to "A, B, C.・ ・ ”Corresponds to the group code. That is, a predetermined switch is operated to arbitrarily specify the individual code “1 to 20”, and another switch is operated to specify which group the individual belongs to. For the correspondence between the individual code and the group code, once the group code is set, the group code corresponding to that individual code will be set when the individual code is specified by operating the individual selection switch after that. It is set automatically.

If M ≠ 1 in the determination in step S28,
In step S46, it is determined whether the value of the mode register M is "2". If M = 2, it means the data read mode. In this case, the process proceeds to step S46, and it is determined whether or not the operated switch is the memory designating switch.

When the memory designating switch is operated, the contents of the register I designating any one of the three types of memories are cyclically changed within the range of "0-2". Then, in the next step S48, it is determined whether or not the data is stored in the memory designated by the register I. When the data is stored, the pointer N is set to "1" in step S49 to set the rank to 1 Specify the order data. As a result, the measurement data having the first rank in the memory designated in the display process described later is displayed.

If no data is stored in the memory designated by register I at this time, step S5
At 0, “0” is set to the pointer N. When "0" is set in the pointer N, no data is displayed in the display process described later.

If it is determined in step S46 that the memory designating switch is not operated, the process proceeds to step S51 to determine whether or not it is the next-order switch. If the operated switch is the next-order switch, it is determined in the next step S52 whether or not the pointer N is "0". If N ≠ 0, the pointer N is incremented by 1 in step S53.

Then, in step S48, it is determined whether or not the value of the pointer N is larger than the last rank of the designated memory, and if the value of N is larger than the last rank of the memory, 1
Since it is when the reading of the data from the rank to the last rank is completed, "1" is set to the pointer N in step S55 and the rank is returned to the head.

If it is not the next-order switch that is operated at this time, it is when another switch other than the above is operated, and in that case, another switch process of step S56 is executed.

The mode register M is determined by the determination in step S45.
If the value of is not "2", the clock mode is M = 0,
In this case, the process proceeds to step S57 to execute the switch process in the clock mode such as the time correction.

When the above switch processing is completed or when there is no switch input, the process proceeds to step S3 of FIG. 3 and it is determined whether or not the value of the mode register M is "0".

If M = 0 in this determination, it means the timepiece mode, so the time display processing of step S4 is executed and the current time is displayed on the display section 9. If M ≠ 0 in the determination in step S3, the process proceeds to step S5 and it is determined whether or not M = 1.
If M = 1, the stopwatch mode is in effect, so the time being measured or the time when the measurement is completed is displayed on the display unit 9 in step S6. Further, the personal code of the measurement data is displayed in step S7, and the group code is displayed in step S8.

If M ≠ 1 in the determination in step S5, the process proceeds to step S9 and it is determined whether or not M = 2. If M = 2, it means the data read mode, so step S10.
Then, it is determined whether or not the register I is "0".

If I = 0, it means that the reading of the data from the measurement time memory TM is instructed. Therefore, in step S11, it is further determined whether or not the pointer N is "0".

If N ≠ 0, then the data of the rank N of the measurement time memory TM designated by the pointer N is read out and displayed on the display unit 9. If N = 0, since no data is stored in the measurement time memory TM to be read, no data is displayed in step S13.

If I ≠ 0 in the determination in step S10,
In step S14, it is determined whether the register I is "1". If I = 1, it means that the reading of the data from the personal total memory PM is instructed. Therefore, it is determined whether or not the pointer N is “0” in step S15 as described above, and N ≠ 0. If there is, the data of the rank N in the personal total memory PM is read out in step S16 and the display unit 9
To display.

If I ≠ 1 in the determination in step S14,
Since I = 2 and the reading of the data of the group total memory GM is instructed, the order N of the group total memory GM is determined in step S18 as described above.
Data is read out and displayed on the display unit 9.

If N = 0 in the determination in steps S15 and 17, the process proceeds to the above-described step S13 and no data is displayed. If M ≠ 2 in the determination in step S9, M =
Since the mode is the mode of displaying the correspondence between the individual and the group 3, the process proceeds to step S19, and the display unit 9 displays the correspondence between the individual code and the group code.

FIG. 5 is a diagram showing an example of a display state in each mode. When the mode switch is operated in the clock mode (M = 0) where the date and current time are displayed,
The mode is switched to the stopwatch mode of M = 1, "0" is displayed on the display unit 9, and the standby state for stopwatch measurement is entered. Immediately after the mode is switched, the previously set personal code and group code are displayed, so if the personal code is not designated, the measurement time is stored in the personal code.

When the mode switch is operated in the above stopwatch mode, the mode is switched to the data reading mode of M = 2. In this data read mode, the measurement time memory TM is first designated, and if data exists, N = 1 and the fastest data "28" in the measurement time is obtained.
Minutes 34 seconds 12 ", personal code" 0
1 ”, group code“ C ”to which the person belongs, ranking“ 1 ”
"Rank" is read out and displayed on the display unit 9.

If the next-order switch is operated in this state,
N = 2 and the second fastest data "28: 54: 2"
4 ”, the personal code“ 15 ”, the group code“ D ”, and the rank“ 2nd ”of the person at the measurement time are read out and displayed on the display unit 9
Displayed in.

When the memory designating switch is operated while the data of the measurement time memory TM is displayed, the next individual total memory PM is designated, and if data is present, N = 1 and the average measurement time for each individual becomes Among them, the fastest data “29 minutes 16 seconds 45”, the personal code “01” of the person at that time, and the rank “1st place” are displayed.

When the next-order switch is operated in this state,
The second fastest data in the measurement data memory TM is read and displayed. Hereinafter, each time the next-order switch is operated, the data of the next order is displayed in order.

When the memory designating switch is operated with the data of the personal total memory PM displayed, the next group total memory GM is designated, and if data is present, N = 1 and the average measurement time for each group is reached. The fastest group data “31:45:23”, the group code “B” at that time, and the rank “1st place” are read out and displayed on the display unit 9.

If the next-order switch is operated in this state,
The data of the second fastest group in the average measurement time by group is displayed. As described above, according to the above embodiment, by specifying the individual code and the group code,
