FIG. 3 shows an arrangement relationship between the display panel 20 of the display device 15 and each switch. That is, the switches SwA and SwB are provided below the display panel 20, and the switches Sw1 to Sw4 are provided on the side surfaces. The display panel 20 includes display units 20A and 20B.
And an item display section 21 is provided. Display unit 20A
Includes 6 digits of 7 for displaying time, measurement time, etc.
A segment display body and the like are arranged, and below the 7-segment display body, three mark display bodies 2 in an inverted triangular shape are arranged.
0a to 20c are arranged. The mark display body 20a
Below 20c, RECORD means record mode and DIS means distance mode.
The characters T and RECALL, which means the recall mode, are printed and displayed. For example, in the case of the distance mode, the mark display body 20b above the DIST character indicating the mode is turned on to indicate that.

The display unit 20B is provided with a 7-segment display body for displaying the date of the day, the measured distance, the measured date, etc., and the measured distance is shown below the display unit 20B. DIST characters, TIME indicating the measurement time

There are five circular parts on which the letters IM are printed and displayed. Normally, these circular parts are shielded from the light from below, and although the above characters cannot be seen, a specific item is designated. When the light is on, the circular part on which the character representing the item is printed is illuminated by light from below and the character can be seen. For example, when the free style is designated, only the circular portion on which the Fr character is printed and displayed is brightened by the light from below, and only the Fr character is visible. Next, the operation of this embodiment configured as described above will be described. FIG. 4 is a general flowchart showing the outline of the operation of this embodiment. That is, in this embodiment, first, in step S1, it is determined whether any switch of the switch unit 12 has been operated and a switch input has been sent. When the switch input is sent, it is determined in step S2 what the set value of the mode register M is currently, that is, which mode the set value is, and the set value is 0. If it is in the clock mode, the process proceeds to the clock mode switch process in step S3, and the current time and the date of the current day are corrected. If the set value is 1 and the record mode is set, the record mode in step S4 is executed. When the switch process is executed and the set value is 2 and the distance mode is set, the distance mode switch process of step S5 is executed, and when the set value is 3 and the recall mode is set, the measured data is stored. The recall mode switch process of step S6 is executed to search the measurement data stored in the section MR.

When any one of the above steps S3 to S6 is completed, or when it is determined in step S1 that there is no switch input, the process proceeds to step S7, where the value of the mode register M is 2 and the distance mode is set. If it is in this mode, the series of processes shown in steps S8 to S13 (detailed later)
After that, the process proceeds to the display process of step S14 for displaying various data on the display device 15. However, if it is determined in step S7 that the distance mode is not set, the display process of step S14 is directly performed. Go to. Then, after the display process of step S14 is executed, the process returns to step S1 and the same operation is repeated thereafter.

FIGS. 5, 6, and 7 are flow charts showing the record mode switch process (step S4), the distance mode switch process (step S5), and the recall mode switch process (step S6), respectively, in detail, and FIG. 9 is a flowchart showing the display process (step S14) in detail, and FIGS. 9 to 14 show changes in display on the display panel 20 in each of the above modes. The operation in each mode will be described in detail below with reference to these drawings.

(B) Operation in clock mode When there is a switch input, it is detected in step S1 and the process proceeds to step S2, where the value of the mode register M is 0.
It is determined in step S3 that the watch mode is set, and step S3 is performed.
In step S7, the process corresponding to the switch input is executed, and the process proceeds to step S7. However, if it is determined in step S1 that there is no switch input, the process directly proceeds to step S7. Then, in step S7, it is determined that the value of the mode register M is not 2, that is, the distance mode is not set, and the process proceeds to step S14, that is, the display process of FIG.

In the above display processing, first, step S1 in FIG.
At 90, it is determined that the value of the mode register M is 0 and the watch mode is set, and the process proceeds to step S191, the current time from the time counting means 4 is displayed on the display unit 20A of the display panel 20, and then the process proceeds to step S192. The date of the day from the calendar counting means 5 is displayed on the display unit 20B. As a result, for example, at 10:08 on October 30, now
When it is seconds, the display on the display panel 20 is as shown in FIG.

To switch from the clock mode to the record mode, the switch Sw3 is operated as shown in FIG. In this case, in response to the operation, the value of the mode register M becomes 1 in step S3 of FIG. 4, that is, the clock mode switch processing, and the mode becomes the record mode.

(B) Operation in the record mode For example, the value of the mode register is 1 and the set state register FC is set to 0, and the record mode is in the normal state (state other than the set state). It is assumed that In order to set the distance other than the selectable swimming distance in the distance storage register Y from this state to the set state, as shown in FIG. 10, first, the switch Sw2 is operated to set the state. To in this case,
In response to the operation, the process proceeds to step S4 in FIG. 4, that is, the record mode switch process in FIG. And step S2
When it is 0, it is determined that the value of the set state register FC is 0 and it is in the normal state, and it is determined that the switch Sw2 is operated in step S35 through steps S21, S25, S30, and in step S36, the measuring flag register FS. It is determined that the set value is 0 and the measurement operation has not started yet, the process proceeds to step S37, and the value of the set state register FC is set to 1 to set the set state. In the display processing, it is determined in step S195 of FIG. 8 that the mode register value is already 1 and the record mode is set, and in step S196, the mark display body 20a is turned on to indicate that the record mode is set. In step S197, it is determined that the value of the set state register FC is not 0 but in the set state, and the process proceeds to step S203 to display the distance already set in the distance storage register Y on the display unit 20B. However, when the distance is not yet set in the distance storage register Y, 0m is displayed and the digit of 1 blinks as shown in b of FIG. 10 (the digit 0 of 1 is elliptical in FIG. 10). Enclosed in indicates that it is in a blinking display state). When setting a specific distance in the distance storage register Y, as shown in FIG. 10, a digit is selected by the switch SwB and a desired value is set in the digit selected by the switch SwA. However, in this case, each time the switch SwB is operated, the operation is detected in step S67 of FIG. 5, the digit selected in step S68 is increased by one digit, and the switch SwA is operated. Each time, the operation is detected in step S65 in the figure, and the value of the digit selected in step S66 is incremented by one. As described above, the distance set in the distance storage register Y is displayed on the display unit 20B in step S203 of the display process of FIG.

After the desired distance is set in the distance storage register Y as described above, in order to return from this set state to the normal state, as shown in FIG.
To operate. At this time, the operation is performed in step S69 in FIG.
In step S70, the value of the set state register FC is returned to 0 to bring it into the normal state.

As described above, in the distance storage register Y,
In order to perform a measurement in a specific swimming competition after setting an arbitrary swimming distance other than that set in advance, first set the swimming distance in the swimming competition before the measurement. (That is, the above 25, 50, 10
0, 200, ... 1650 m) and an arbitrary distance set in the distance storage register Y and selected. In this case, the switch Sw1 is operated as shown in FIG. 11, and each time the switch Sw1 is operated, it is detected in step S25 of FIG. 5, and the distance designation register D is detected in step S26.
It is determined whether or not the value of the distance designation register D exceeds 10 in step S27 while increasing the value of 1 by 1, and if it exceeds, the value of the distance designation register D is reset to 0 in step S28. At this time, in the display processing of FIG. 8, it is determined whether or not the value of the distance designation register D set as described above in step S200 is 0, and when it is 0, it is set in the distance storage register Y in step S201. The displayed arbitrary distance is displayed on the display unit 20B, and if it is a value other than 0, the process proceeds to step S202, and the above-mentioned distance designated by the value (for example, 2 when the value of the distance designation register D is 1).
5m, 50m when 2) is displayed on the display unit 20B.

As described above, after the swimming distance is designated, the switch Sw4 is operated as shown in FIG. 11 to set the item of the swimming competition. In this case, each time the switch Sw4 is detected in step S30 of FIG. 5, the item code value of the item register SR is increased by 1 in step S31 while the item code value of the item register SR is increased by 4 in step S32. Check if the number exceeds 4, and if it exceeds 4, step S
At 33, the item code value of the item register SR is returned to 0. Then, in this case, in the display processing of FIG.
At 9, the item corresponding to the value of the item register SR is displayed on the item display section 21. As described above, when the distance designation register D is set to 1 and the swimming distance is set to 25 m, and the race code SR is set to the race code 1 and the free style is designated as the race, the display on the display panel 20 is , B in FIG.

After completing the above preset operation, as shown in FIG. 11, at the start of the swimming competition,
The switch SwA is operated. At this time, the operation is detected in step S40 of FIG. 5, it is determined in step S41 that the value of the measuring flag register FS is 0, and then the value of the measuring flag register FS is set in step S42. Further, in the next step S43, the RS flip-flop 6 is set to the set state, the signal from the frequency dividing circuit 3 is sent to the time measuring circuit 8, and the time measuring circuit 8 starts the time measurement. Next, in step S44, it is determined whether or not the measurement date is stored in the measurement date storage register KD (that is, whether a reset operation described later has been performed between the present measurement and the previous measurement), and if not stored, Step S
At 45, the date of the day from the calendar counting means 5 is stored in the measurement date storage register KD.

After the measurement is started as described above, the measurement time measured by the time measuring circuit 8 is displayed on the display section 20A in step S198 of the display process (FIG. 8).

When the swimming competition is finished, the switch SwA is operated again in accordance with the completion (see FIG. 1).
In this case, the operation is detected in step S40 of FIG. 5, it is determined in step S41 that the value of the in-measuring flag register FS is 1 instead of 0, and then in step S46, The value of the in-measuring flag register FS is set to 0, and in step S47, the RS flip-flop 6 is reset to stop the measuring operation of the time measuring circuit 8. Time measuring circuit 8 measured in this way
The measurement time of is continuously displayed on the display unit 20A in step S198 of the display process (FIG. 8) as described above. For example, when the measured time in the 25m freestyle competition of the above example is 15 seconds 27, the display on the display panel 20 is as shown in FIG. 11c.

The measured data of this time measured as described above is reset from the time measuring circuit 8 and the measured data storage unit MR is
At the time of the reset operation stored in FIG. 11, the switch SwB is operated as shown in FIG. 11. At this time, the operation proceeds to step S50 from step S40 in FIG. At 0, it is determined that the measurement has already been completed, then at step S51 it is confirmed that the measurement date is stored in the measurement date storage register KD, and at step S52, the value of the storage data number register I is 20. If the value is less than 20, the value of the storage data number register I is set to 1 in step S53.
The measurement date of the measurement date storage register KD in each area corresponding to the row designated by the storage data number register I in the measurement data storage unit MR, that is, the row of the row address MR ₁ , Time measurement circuit 8
The measurement time, the item of the item register SR, and the distance of the distance designation register D are stored. Further, in step S55, the measurement data is measured in the record mode in the first bit of the row of the measurement data storage unit MR, that is, the area A1. 0 is stored to store the fact that it is data. On the other hand,
When it is determined in step S52 that the value of the storage data number register I has reached 20 instead of less than 20,
The process proceeds to step S60, the stored data of each row of the measurement data storage unit MR, (becomes i.e. the data for row address MR ₁ extinguished) the row address, each stored in a shift towards one less, in step S61 , The measurement data of this time on the row of the row address MR ₂₀ , that is, the date of the measurement date storage register KD, the measurement time of the time measuring circuit 8,
The item of the item register SR and the distance of the distance designation register D are stored, and in step S62, the area A of the above row is stored.
Store 0 in 1.

As described above, step S55 or S6
After the processing of step 2 is completed, the process proceeds to step S56, a reset signal is sent to the time measuring circuit 8 to erase the presently set measurement time, and further, step S56.
At 57, the date stored in the measurement date storage register KD is deleted. After the above processing, the time measuring circuit 8
Since the measurement time of 0 is 0, 0 is displayed on the display unit 20A in step S198 of the display process (FIG. 8). Therefore, the display on the display panel 20 is as shown in FIG.

It should be noted that after the measurement of a certain swimming competition is completed, the switch SwB is not operated to reset the time measuring circuit 8 as described above, that is, the measured data of that time is stored in the measured data storage unit MR. Instead, when the switch SwA is operated to perform further measurement, the processing of steps S40 to S43 of FIG. 5 is executed as described above (that is, the measurement time is added to the measurement time by the time measurement circuit 8 and measured. Then, in step S44, it is determined that the month / day (the month / day set in the previous measurement) is already set in the measurement month / day storage register KD, and the switch Sw is set.
The processing associated with the operation of A is completed. When the measurement is performed as described above, and thereafter the measurement is finished in the same manner as described above, and the switch SwB is further operated to reset the time measuring circuit 8, steps S50 to S57, S60.
Through S62, the sum of the measurement times is stored in the area A3 of one row of the measurement data storage unit MR.

(C) Operation in Distance Mode When switching from the record mode to the distance mode, the switch Sw3 is operated as shown in FIG.
At this time, the operation is detected in step S21 of FIG. 5, it is determined in step S22 that the value of the measurement-in-progress flag register FS is 0, and the measurement is not in progress. Set to distance mode. In this way, after the distance mode has been entered, it is determined in step S7 in FIG. 4 that the mode register M has been set to 2, and the distance mode has already been entered. In step S8, the cycle time flag register FA Is checked to see if it is in the cycle time measurement state. If it is not in that state, the process directly proceeds to step S14, that is, the display process of FIG. 8, and in step S205, as described above, the mode register M It is confirmed that the value of is already 2, and then the mark display body 20b is turned on in step S206 to indicate that the distance mode is set, and step S20
In step 8, it is determined that the value of the set state register FC is 0, that is, the set state is not yet set and the normal state is set. Then, in step S208, the total distance of the total distance register L is displayed on the display unit 20A. In step S209, the measurement time of the time measurement circuit 8 is displayed on the display unit 20B. In this case, since the measurement has not started yet, the display of the display units 20A and 20B of the display panel 20 is as shown in FIG. As shown, both are 0.

There are two types of measurement in the distance mode, one in the cycle time ON state and one in the normal measurement state other than the cycle time ON state. Whichever measurement is performed, the swimming is performed prior to the measurement. It is necessary to set the length of the pool for competition, that is, the pool course length, and it is also necessary to set the cycle time when measuring in the cycle time ON state. The data is set in the set state, and the switch Sw2 is operated as shown in FIG. 12 to bring the set state. In this case, the operation is detected in the distance mode switch process of step S5 of FIG. 4, that is, step S90 of FIG. 6, and it is determined in step S91 that the value of the in-measuring flag register FS is 0 and that the measurement is not yet started. In S92, the value of the set state register FC is set to 1 to bring it into the set state, and in step S93, 0 is set in the data type designation register Q to set the set data type to the pool course length. In this way, when the set data type is the pool course length, the switch SwA or SwB is operated as shown in FIG. 12 to set the pool course length. At this time, the pool course length is set at each time. It is detected in step S145 or S150 in FIG. 6, and the process proceeds to step S147 or S152, and the pool course length of the course distance register K is increased or decreased by 1 m. The pool course length set in the course distance register K in this way is displayed on the display unit 20A in step S211 of the display process of FIG. 8 (see b in FIG. 12).

In order to set the cycle time in the cycle time register R in preparation for measurement in the cycle time ON state, the switch Sw4 is operated in the above state as shown in FIG. The value of Q is set to 1 and the data to be set is the cycle time.
In this case, the operation of the switch Sw4 is detected in step S140 of FIG. 6, the value of the data type designation register Q is incremented by 1 in step S141, and step S142 is performed.
Then, it is judged that the value of the data type designation register Q has not exceeded 2 and the processing is ended. After the setting target data is set as the cycle time in this way, the switch SwA or SwB is operated to set a desired cycle time. In this case, the desired cycle time is set at each step S145 of FIG. It is detected in S150, and the cycle time of the cycle time register R is increased or decreased by 5 seconds in step S148 or S153. The cycle time set in this manner is displayed on the display unit 20A in step S216 of the display process (FIG. 8) (see c in FIG. 12).

As described above, after setting the course length and the like, if the measurement to be performed from now on is the measurement in the cycle time ON state, first the switch Sw4 is operated, and then the switch SwA is operated (see FIG. 12). ). At this time, the operation of the switch Sw4 is detected in step S140 of FIG. 6 and the value of the data type designation register Q is incremented by 1, and then 2, the operation of the switch SwA is detected in step S145, and the cycle time flag register F is detected in step S149.
The value of A is set to 1 and the cycle time is in the ON state. When the measurement to be performed from now on is not in the cycle time ON state, the switches Sw4 and S4 are used.
Do not operate wA.

After each processing in the set state is completed as described above, the set state is returned to the normal state. At this time, the switch Sw2 is operated as shown in FIG. To do. In this case, the operation is detected in step S154 of FIG. 6, and the value of the set state register FC is set to 0 in step S155 to bring it to the normal state.

As described above, after the normal state,
Measurement starts, but first the cycle time is not on,
The measurement in the normal state will be described. In this case, FIG.
As shown in, the switch SwA is operated simultaneously with the start of measurement (that is, the start of the swimming competition). The operation is detected in step S95 in FIG. 6, and then step S96.
Then, it is determined that the value of the measuring flag register FS is 0 and the measuring process is not started yet. Then, the value of the measuring flag register FS is set to 1 in step S97, and the RS flip-flop 6 is set in step S98. In the set state, the time measurement circuit 8 starts measuring time, and in step S99, initial setting is performed to clear the total distance register L. In step S100, the value of the cycle time flag register FA is not 1 and normal measurement is in progress. It is determined that there is, and in the next step S104, it is determined whether or not the date is already stored in the measurement date storage register KD. If not stored, in step S105, the date of the current day from the calendar counting means 5 is determined. The measurement date storage register KD
The measurement date is stored in.

As described above, after the time measurement circuit 8 has started measuring the time, it is determined in step S7 of FIG. 4 that the value of the mode register M is 2 and the distance mode is set, and step S8 is performed. It is determined that the value of the cycle time flag register FA is not 1 in step S14, that is, the display process of FIG. 8 is performed, and the total distance of the total distance register L is displayed on the display unit 20A in step S208 through steps S205 to S207. Is displayed (in this case, 0 is displayed because the total distance of the total distance register L is 0), and in step S209, the measurement time of the time measurement circuit 8 is displayed on the display unit 20B. Thus, when one minute has elapsed from the start of measurement, the display on the display panel 20 becomes as shown in b of FIG.

As described above, the measurement is advanced, and when there is a turn (that is, when there is swimming only for the length of the pool course), the switch Sw is changed each time.
1 is operated, but in this case, each time the operation is performed, it is detected in step S135 of FIG. 6, and the value of the in-measurement flag register FS is 1 in step S136. Judge that there is, total distance register L
Of the pool course length set in the course distance register K, and the value of the cycle time flag register FA becomes 1 in the next step S138.
Instead, the operation of judging that the cycle time is not in the ON state and ending the processing accompanying the switch operation is repeated. Then, as described above, the total distance set in the total distance register L is displayed in step S of the display process (FIG. 8).
It is displayed on the display unit 20A at 208. Then, for example, there is the first turn, and the switch Sw1 is operated,
When the total distance of the total distance register L reaches 25 m (pool course length), the display state of the display panel 20 is as shown in FIG.
It becomes something like c in 3.

To proceed with the measurement as described above and stop the measurement, the switch SwA is operated as shown in FIG. At this time, the operation is detected in step S95 of FIG. 6, it is determined in step S96 that the value of the measuring flag register FS is 1 instead of 0, and then in step S110, the value of the measuring flag register FS is changed. Set the value to 0,
In step S111, the RS flip-flop 6 is reset and the measurement by the time measuring circuit 8 is stopped. In step S112, the total distance of the total distance register L is lengthened by the pool course length of the course distance register K, and then step S
After 112, the process in this case ends. After that, in the display process (FIG. 8), the total distance of the total distance register L is displayed on the display unit 20A in step S208, and the step S2 is performed.
At 09, the current measurement time set in the time measurement circuit 8 is displayed on the display unit 20B. For example, when the total distance of the total distance register L is 1350 m and the time measured by the time measuring circuit 8 is 1 hour and 15 minutes, the display on the display panel 20 is as shown in d of FIG.

The above is the measurement operation in the case of the measurement in the normal state of the distance mode. Next, the measurement operation in the above-mentioned cycle time ON state will be described. Also in this case, as shown in FIG. 14, the switch SwA is operated at the same time as the start of the measurement, but accordingly, as in the case of the measurement in the normal state described above, steps S95 to S9 in FIG.
9 is executed, it is determined in step S100 that the value of the cycle time flag register FA is 1 and the cycle time is in the ON state, and the process proceeds to step S101 to set the cycle time set in the cycle time register R. The subtraction timer circuit 11 is set, and step S10 is performed.
In step 2, the timer counting flag register FT is set to 1 and the fact that the subtraction timer circuit 11 is used to start measuring the remaining time is stored. In step S103, the RS flip-flop 9 is set to the subtraction timer circuit. The measurement by 11 is started, and thereafter, similarly to the above, in step S104, it is determined whether or not the measurement date is stored in the measurement date storage register KD, and if not stored, step S104 is executed.
In step 105, the date of the calendar counting means 5 is stored in the measured date storage register KD.

As described above, after starting the measurement,
As in the case described above, every time there is a turn, the switch Sw1
However, before the turn is made, that is, before the switch Sw1 is operated, when the time corresponding to the cycle time has elapsed and the time-up signal is sent from the subtraction timer circuit 11, this is Step S10 in FIG.
In step S11, the total distance of the total distance register L is made longer by the pool course length of the course distance register K. In step S12, a new cycle time is set in the subtraction timer circuit 11 to start remeasurement, In step S13, a signal is sent to the sounding device 13 to notify that the time has been up, and the time-up sound is generated for a certain period of time. Then, the process proceeds to step S14, that is, the display process of FIG. In the display process, the total distance of the total distance register L is displayed on the display unit 20A in step S208 as in the above, and the measurement time of the time measuring circuit 8 is displayed in the display unit 20B in step S209. For example, after setting the pool course length of the course distance register K to 25 m and the cycle time of the cycle time register R to 2 minutes, the cycle time 2 is set after the measurement is started and before the switch Sw1 is operated.
When the minutes have passed, 25 m is displayed on the display unit 20A and 2 minutes is displayed on the display unit 20B as shown in FIG. 14B, and a time-up sound is generated.

On the other hand, in the measurement in the cycle time ON state, when the swimming is fast and there is a turn before the time is up, the switch Sw1 is operated each time, but in this case, each time, the above-mentioned operation is performed. The processing of steps S135 to S137 is executed similarly to the normal measurement of
Thereafter, it is determined in step S138 that the value of the cycle time flag register FA is 1, and step S138
At 139, the cycle time of the cycle time register R is set in the subtraction timer circuit 11, and the measurement of the cycle time is newly started. Then, step S20 of the display process
8, in S209, the total distance of the total distance register L and the measurement time of the time measuring circuit 8 are displayed on the display units 20A and 20B. Then, before the time is up, that is, when the measurement time reaches 3 minutes, there is a turn of 50 m, and when the switch Sw1 is operated, the display on the display panel 20 becomes as shown in FIG.

Note that such measurement in the cycle time ON state is extremely effective for measurement in so-called interval training, which is widely adopted as a training method. That is, if the sum of the time required for swimming at a certain distance and the rest time after that is set as the cycle time in the cycle time register R, a time-up sound is produced after the swimming at the certain distance. It is possible to continue interval training very easily by repeating the operation of resting until the time of occurrence and restarting the swimming practice when the time-up sound is generated.

As described above, when the measurement in the cycle time ON state in the distance mode is finished and the measurement operation is stopped, the switch SwA is operated as shown in d of FIG. At this time, the operation is detected in step S95 of FIG. 6, it is determined in step S96 that the value of the measuring flag register FS is 1 and the measurement is in progress, and then in step S110, the measuring flag register FS is checked. The value is set to 0, the RS flip-flop 6 is reset in step S111 to stop the measuring operation by the time measuring circuit 8, and the total distance of the total distance register L is made longer by the pool course length of the course distance register K in step S112. In step S113, the value of the cycle time flag register FA is 1, and it is determined that the measurement was performed in the cycle time ON state.
Next, at step S114, the timer counting flag register FT is set to 0 to store the stop of the measurement by the subtraction timer circuit 11, and then the process proceeds to step S115 to set the RS flip-flop 9 to the reset state and stop the measurement by the subtraction timer circuit 11. . Then, in the subsequent display process (FIG. 8), the measurement data of this time is displayed on the display units 20A and 20B in steps S208 and S209. For example, when the total distance of the total distance register L is 1350 m and the measurement time of the time measuring circuit 8 is 1 hour and 15 minutes, the display units 20A, 2
The display of 0B is as shown in d of FIG.

As described above, in order to store the measurement data measured in the distance mode in the measurement data storage unit MR, as in the record mode described above,
The switch SwB is operated as a reset operation. In this case, the operation is detected in step S120 of FIG. 6, the processes of steps S121 to S132 are executed, and the measurement data is stored in any row of the measurement data storage unit MR.
The above-mentioned processing is substantially the same as the above-described processing in the record mode (steps S50 to S57 and S60 to S62 in FIG. 5). However, in the above record mode,
1 in the row that stores the measurement data in steps S55 and S62
Although 0 is stored in the bit position, that is, in the area A1 to indicate that it is the measurement data in the record mode, in the distance mode this time, the area of the row in which the measurement data is stored in steps S126 and S132 corresponding to the above steps. A1 is stored in A1 to indicate that it is the measurement data in this distance mode. Further, in the measurement in the distance mode, the total distance register L is used unlike the measurement in the record mode, so that the step S12 is performed.
A process for clearing the total distance register L is added to 8.

As in the case of the record mode described above, also in this distance mode, after the first measurement is stopped, for example, the switch SwB is not operated to perform the reset operation, and the second measurement is started. When I did
Since the measurement is restarted without performing the processing of steps S127 and S128, that is, the processing of clearing the first measurement time remaining in the time measurement circuit 8 and the total distance of the total distance register L, the time measurement circuit 8 The measurement time will be the sum of the first time and the second time, and the reset operation after the second measurement will
The total measurement time and the like during the first and second measurements are stored in the corresponding area of one row of the measurement data storage unit MR.

(D) Operation in Recall Mode As described above, when the measurement data stored in the measurement data storage unit MR in the record mode and the distance mode is displayed on the display panel 20 for confirmation, First, the recall mode is set. To enter the recall mode, the switch Sw3 is operated in the above-described distance mode as shown in FIG. At this time, the operation is detected in step S76 of FIG. 6, the value of the measuring flag register FS is 0 in step S77, it is determined that the measurement is not in progress, and the value of the mode register M is determined in the next step S78. Is set to 3, and the recall mode is set. Then, in step S79, it is determined whether the value of the storage data number register I is other than 0, that is, whether the measurement data is stored in any row of the measurement data storage unit MR,
If stored, the process proceeds to step S80 to set 1 in the address designation register H, and in step S81,
The value (that is, 0 or 1) of the area A1 of the row designated by the addressing register H, that is, the row of the row address MR ₁ among the rows of the measurement data storage unit MR displays the measurement data in either the record mode or the distance mode. It is checked whether or not the value is equal to the value of the display data type flag FE (that is, 0 or 1) that indicates whether or not it is set. When they are equal,
In step S82, the display data designation register P is set to the value 1 of the address designation register H.
When it is determined at 81 that the value of the area A1 is not equal to the value of the display data type flag FE, the value of the address designation register H is increased by 1 at step S83, and the address designation register H is increased at step S84 each time. Of the address data register H is confirmed in step S81.
It is determined whether the value of the area A1 of the row designated by the value of is equal to the value of the display data type flag FE. When a line in which the value of the area A1 is equal to the value of the display data type flag FE is found, the value of the address designation register H at that time is set to the display data designation register P in step S82.
If the same value as the value of the display data type flag FE is not set in those areas A1 even after checking all the stored rows, it is detected in step S184 and step S85 Then, the display data designation register P is set to 0.

In the subsequent display process (FIG. 8), it is determined in step S220 whether the value of the display data designation register P is other than 0. If it is 0, the process proceeds to step S235 and the measured data is stored in the display section 20A. If it is not 0, it is determined in step S221 whether the value of the display data type flag FE is 0, that is, whether the measurement data in the record mode is designated as the display target. When the value of the display data type flag FE is 0 and the measurement data in the record mode is designated, the mark display bodies 20a, 20c are indicated in step S222 to indicate that fact.
Is turned on, and in step S223, the measurement data storage unit M
The measurement time stored in the area A3 of the row designated by the display data designation register P of R is displayed on the display unit 20A.
In step S224, the area A5 of the above line is displayed.
The item stored in the item is displayed on the item display section 21, and in the next step S225, it is determined whether the value of the display data designation register FD is 0. If it is 0, the process proceeds to step S233. Area A of the above line in 20B
The measurement date of 2 is displayed, but when it is 1 instead of 0, the process proceeds from step S225 to step S226, and the distance stored in the area A4 of the row is displayed on the display unit 20B.

On the other hand, when the value of the display data type flag FE is 1 instead of 0 in step S221 and it is determined that the measurement data in the distance mode is designated as the display target, step S230 is provided to indicate that fact. The mark display bodies 20b and 20c are turned on with, and in step S231, the distance of the area A4 of the row designated by the display data designation register P of the measurement data storage unit MR is displayed on the display unit 20A. Next, in step S232, it is determined whether or not the value of the display data designation register FD is 0, and if it is 0, the process proceeds to step S233 and the measurement date of the area A2 of the above line is displayed on the display unit 20B. However, when the value is 1 instead of 0, the process proceeds to step S234 and the measurement time of the area A3 of the above line is displayed on the display unit 20B.

For example, as shown in FIG. 9d, the mark display bodies 20a and 20c are lit, indicating that the measurement data is being displayed in the record mode in the recall mode, and the measurement data is stored in each display section. A state in which the measurement data of a specific row of the section MR is displayed, that is, the measurement time is 15 seconds 27 on the display section 20A and the measurement date is October 1

To operate. In this case, this operation is detected in step S185 of FIG. 7, the display data designation register FD is changed from 0 to 1 in step S186, and the display data designation register FD is set to 1 in step S225 of the subsequent display process (FIG. 8). That is detected, step S22

As described above, the measurement data storage unit MR
From the state where the measurement data in the record mode stored in a specific row of is displayed on the display panel 20, the display is changed to check the measurement data in the record mode stored in another row. At this time, the switch SwA is operated. At this time, this operation is detected in step S170 of FIG. 7, the value of the display data designation register P is other than 0 in step S171, and the measurement data is not stored in any row of the measurement data storage unit MR. If so, the process proceeds to step S172, the value obtained by adding 1 to the value of the display data designation register P is set in the address designation register H, and the process proceeds to step S173. This step S17
In No. 3, it is determined whether the value of the address designation register H exceeds the value of the storage data number register I, that is, whether the confirmation of each measurement data of the measurement data storage unit MR has completed one cycle, and the cycle is completed. When step S
After proceeding to step 173 and returning the value of the address designation register H to 1, the procedure proceeds to step S175, and when one cycle is not finished, directly from step S173 to step S175.
Proceed to. Then, in step S175, the value of the area A1 of the row designated by the addressing register H of the measurement data storage unit MR is the value of the display data type flag FE, that is, 0, that is, the measurement data of the row is in the record mode. If it is 0, the value of the address designation register H is set in the display data designation register P in step S176.
If it is determined in 75 that the value of the area A1 is 1 instead of 0, that is, it is determined that the measurement data stored in the row is the measurement data in the distance mode, the addressing register is set in step S177. Steps S178 to S1 while increasing the value of H by 1
By repeating the processing of S80 and S175,
Each line in R is inspected and the line in which the measurement data in the record mode is stored is searched. When a line in which the measurement data in the record mode is stored is found, the process proceeds to step S176 and the value of the address designation register H is set in the display data designation register P. In the above search, when the value of the addressing register H exceeds the value of the storage data number register I, that is, when the inspection up to the last row in which the measurement data is stored is finished, the step S178 is executed. The value of the addressing register H is set back to 1, and the value of the addressing register H becomes equal to the value of the display data specifying register P. If the measurement data in the record mode is not stored in addition to the measurement data in the existing record mode, it is detected in step S180, and the search ends.

After the processing associated with the operation of the switch SwA as described above, the process proceeds to the display processing, and the processing of steps S220 to S226 and S233 is performed in the same manner as described above, and the measurement data of the measurement data storage unit MR is stored. The measurement data of the line designated by the display data designation register P is displayed on the display panel 20. Also in this case, the switch Sw4 is operated to switch the data to be displayed on the display section 20B (steps S85 and S in FIG. 7).

Then, the process proceeds to step S164 and thereafter. The processing of steps S164 to S168 is the same as in FIG.
This is the same as the processing of steps S81 to S85 in step S81, and while increasing the value of the addressing register H by 1 (step S166), the distance to the row of the measurement data storage unit MR specified by the value of the addressing register H is increased. This is a search process for checking whether measurement data in the mode is stored (step S164). In this search process, when the line in which the measurement data in the distance mode is stored is found, the value of the address designation register H at that time is set in the display data designation register P in step S165, and which line Also records the measurement data in the record mode, and if the line storing the measurement data in the distance mode is not found, the display data designation register P is selected in step S168.

After the switch process is completed as described above, the process proceeds to the display process (FIG. 8), and it is determined in step S220 whether the value of the display data designation register P is 0. If it is 0, in step S235. The display unit 20A displays that the measurement data in the distance mode is not stored in the measurement data storage unit MR, but if the value of the display data designation register P is not 0, the display data type flag FE is set in step S221. It is determined that the value is 1 instead of 0, and the process proceeds to step S230. Step S230
Then, as shown in FIGS. 9F and 9G, the mark display bodies 20b and 20c are turned on to indicate that it is in the recall mode and the measurement data is being displayed in the distance mode. After that, in step S231, the distance stored in the area A4 of the row designated by the display data designation register P is displayed on the display unit 20A, and the process proceeds to step S232 where the value of the display data designation register FD is 0.
