111 works! 1''1 FIG. 5 is a general flowchart showing an overview of the overall operation of this electronic timepiece. Step T occurs when the power is turned on.
In l, the system is in a standby state (HALT state) until there is a request for timekeeping timing or key human power.When the timekeeping timing is reached, the process advances to step T2, and after the timekeeping process is executed, the stopwatch process (step T3) is executed. be done. Furthermore, when a key code corresponding to an operation key is output from the input section 16, a corresponding key program is designated (step T4), and key processing is performed (step T5).

Stop-7 Watch Processing FIG. 6 is a flowchart showing the specific contents of the stop-7 watch process shown in Figure 5 of the imperial edict. First, when entering this flow, the presence or absence of carry of 100Hl is checked in step Tll. As a result, if no carry is detected, the process jumps to step T27 (display processing), but if carry is detected, the process jumps to step T27 (display processing). is mode register V
The contents of ,S,0 are examined. That is, the current stop war 2,000 measurement mode (V = 1), lap measurement mode (S =
1), target time display mode (0=1) is checked. Here, if one of the modes mentioned above is set, the process proceeds to step T15, a time counting process is executed, time data of 1/loo second is inserted into the contents of the measurement register Y1, and the stopwatch is set. The measurement time is updated. Note that if the mode is not one of the three modes described above, the measurement process (step T15) and the sound emission process (step T1) described later are performed.
7) is not executed.

When such time measurement processing is completed, the next step 716
The process proceeds to Step T16, where it is checked whether the stopwatch carries seconds or not (Step T16).This process compares the preset target value with the measured time every 1 second of the measured time, and if they match. This is to execute a sound emitting process (step T17) that sometimes generates an alarm sound. In this case, generation of the alarm sound is regulated according to alarm on/off data corresponding to the target time set in advance in the target value setting memory PS.

Then, in the next step T18, it is checked whether or not the clock register yo carries seconds. Here, if there is no second carry, the process jumps to step T27 (display processing), but if a second carry is detected, the contents of mote registers S and T are checked (steps T19, T2O), that is,
It is now checked whether the lap measurement mode (S=1) or the lap stop mode (T=1) is set. Here, in the lap measurement mode, in order to activate the auto-return function, the 1 of the 5-second counter Co is incremented (step T21), and as a result, the 5-second counter C
When it is detected in step T22 that fl of o has become "5", the mode is changed (step T23).
), that is, when the 5 second counter Co detects that 5 seconds have elapsed in the lap measurement mode, the lap measurement mode is canceled and the mode is dynamically switched to the stopwatch measurement mode. Also, step T2 indicates that the lap stop mode is present.
If it is detected as 0, auto return af as described above.
5 seconds counter C to activate l.

i is incremented by 1 (step T24), and the result is

When it is detected in step T25 that the value of the 5 second counter Co has become "5", the mode is changed (step T26), that is, in the lap stop L mode, the 5 second counter 9Ca indicates that 5 seconds have elapsed. When detected, the lap stop mode is canceled and automatically switched to the stopwatch stop mode.

Note that if it is detected in steps T19 and T2O that the mode is not lap measurement mode or lap stop mode, or if automatic mode switching is performed in steps T23 and T26, step T27 (display processing) is executed, respectively. . After executing this display process, this stopwatch process ends and you can exit this flow.

Key processing associated with stopwatch operation and display unit 1 Next, the operation associated with the operation of switches 5l-55 is shown in FIGS.
Flowchart shown in Figure 1O and Figures 11 to 13
This will be explained with reference to the display shape J ball shown in the figure. Here, the seventh
The figure is a flowchart executed by operating the switch S2, FIG. 8 by the switch S3, FIG. 9 by the switch S4, and FIG. 10 by the operation of the switch S5. Further, FIG. 11 shows the overall display state that changes depending on the operation of each switch. Further, FIG. 12 shows the display state in the all data recall mode, and FIG. 13 shows the display state in the current data recall mode.

Processing of switch SL> The switch SL is used to specify the basic mode, and each time this switch S1 is operated, the value of the mote register M changes to "O", rlJ, "2", "0", etc. It changes like... Here, when M=O, the basic clock mode,
When M=1, it corresponds to the stopwatch mode, and when M=2, it corresponds to other afl modes, and each time the switch S1 is operated, these modes are sequentially and cyclically changed to νJ. FIG. 11 shows the display state in this case. In the basic clock mode (M=0), the upper display section 2 shows the day of the week and the year, the middle display section 3 shows the month and day, and the lower display section 4 shows the hours, minutes, and seconds. Is displayed. In this basic clock mode, switch 31
When the mode register M is set once, I1 of the mode register M becomes rlJ, and the mode is switched to the stopwatch mode. When the switch Sl is operated in this stopwatch mode, this stopwatch mode is canceled and the mode is switched to another function mode (M=2).

Processing of switch S2 and switch S6> Every time switch S2 is operated in the stopwatch mode, the flow shown in FIG. 7 is started, and steps T31 to T are executed.
At 35, a mode register is entered, and the mode is determined based on the contents of ■, W, S, and T. In this case, reset mode (L=1), stopwatch measurement mode (V
=1), stopwatch stop W mode (W-t), lap measurement mode (S=1), lap stop mode (T=1)
The operation of the switch S2 becomes effective only when the mode is set to one of these modes.

Reset mode Assuming that the reset mode (L=1) is currently set, the remaining number of data memories Xo-X29, for example "30", is displayed in the middle row, as shown in FIG. Zeros are displayed in all digits in the upper and F rows. The number of measurement data that can be recorded can be confirmed by displaying the number of remaining pieces of memory.

Reset mode j l Marking setting mode L When switch S6 is operated in the reset mode, the [1 standard setting mode (Q = 1) is set. In this setting mode, before starting the measurement operation of the stopwatch,
This is to set the lap time that should be the 1-1 mark.
As shown in Fig. 4, target times such as "1 minute 00 seconds", "2 minutes 00 seconds", and "3 minutes 00 seconds" are set in the mark A1 setting memory PS. [A flag indicating whether or not to generate an alarm line when the target time is reached is also set. In this way, [After setting the 1 mark time, operate the 1q switch S6.] This cancels this setting mode and returns to the original reset mode.

Therefore, in the reset mode of the stopwatch, the switch S6 functions as a set/cancel key for the target value setting mode (see FIG. 11).

Reset mode→stopwatch measurement mode On the other hand, when switch S2 is operated in reset mode, this is detected in step T31 and the process proceeds to step T36, where the mode is changed. That is, the reset mode is canceled and the mode is switched to the stopwatch measurement mode (v=i). Then, in the next step T37, the current date data stored in the clock register yo is read out and recorded in the RAM 20. In this case, the contents of the empty address register Zo are transferred to the current start address register Ao, and the date data is written into the data memory specified by the contents of the current start address register A, initially the data memory Xo. Therefore, when the switch S2 is operated in the reset mode, the stop war 2,000 measurement mode is entered and the measurement operation is started, and at the same time, the current data with [1] is recorded in the empty area of the RAM 20. In addition to writing the date data, a total of 4 measurement times from start to stop/stop are recorded in the empty area corresponding to the date data.
- An identification code rQJ indicating that it is time (finish time) is added. When the stopwatch is set to the measurement mode in this way, v=1 in Figure 11.
As shown in the figure, the measurement time from the start, for example, "56 seconds 99", is digitally displayed in the upper and lower rows, respectively, and the number of used data memories, for example, r, is displayed in the middle row.
olJ is displayed digitally.

Stopwatch measurement mode = stopwatch stop mode In the above stopwatch measurement mode, switch S2
When is operated, the process proceeds to step T38, where the measurement mode is canceled and switched to the stopwatch stop mode. Then, proceeding to the first step T39, switch S2
I! The measurement time (finish time) of the writing point is stored in the data memory specified by the contents of the current start address register AO, and the contents of the empty address register Zo are incremented by 1. Therefore, in the stopwatch measurement mode, when the switch is When S2 is operated, step 7 enters the watch stop mode and the measurement operation is stopped, and the measured time at the time of the stop is recorded as the finish time. When the ST-2 watch stop mode is set, the latest lap time is displayed in the upper row, for example, "1 minute 12 seconds 04", as shown in Figure W=1 of FS11.
In the middle row, a stop mark display is lit together with "Used water ar02 of data memory", and the lighting of this stop mark clearly indicates that the measured time digitally displayed in the lower row is the finish time. In this stopwatch stop mode, when switch S2 is operated, this is detected in step T33 and step T4 is detected.
0 and the mode change is performed. That is, the stopwatch stop mode is canceled and switched to the stopwatch measurement mode, and the measurement operation is started again. In this case, the measurement time is the previous finish time plus the current measurement time by 1Afl.

In addition, when starting the current measurement operation, the data measured last time is not cleared and is held as is, and the finish time obtained this time is recorded in the next empty area of the data memory in correspondence with the date data. . Therefore, in this embodiment, a maximum of 30 measurement data can be recorded corresponding to 30 data memories Xo-X29. Of course, if 30 data memories are required for one measurement, the contents of each memory are cleared.

Lap display mode (lap measurement mode - lap stop mode) Switch S2 also functions as an effective key in lap display mode (R = 1), and in this case, switch S2 is operated in lap measurement mode (s = i). If so, this is detected in step T34, and step T4
1, the mode is changed to be described later, and the lap stop F mode is entered. Also, lap stop mode (T=1
), when switch S2 is operated, step T3
This is detected in Step 5 and the process proceeds to step T42, where the mode is changed to be described later and becomes the lap measurement mode.

Processing of switch S3 and switch S2> Switch S
Every time 3 is operated, the flow shown in Fig. 8 starts to be executed.
In steps T51-T53, mode registers V, S, W
The mode is classified into I based on the contents of . In this case, stopwatch measurement mode (V = 1), lap measurement mode (S = 1), stopwatch stop mode (
The Sweep 7,000 S3 operation is valid only when one of the modes (W=1) is set.

Stop/Puwatch measurement mode→Lap display mode When switch S3 is operated in the stopwatch measurement mode (v=i), this is detected in step T51 and the process proceeds to step T54, where the mode is changed. From this measurement mode to lap display mode (R=
VJ is replaced by the lap measurement mote (S=1) in 1). Then, the measured time at the time of the switch S3 operation is recorded as lap time in the data memory of the RAM 20, and
The value of empty address register Zo is incremented by 1 (step T
55). When the switch S3 is operated in the stop/stop watch measurement mode in this manner, the lap measurement mode is entered and the lap time at this time is recorded. In this case, as shown in FIG. 4, the lap times are sequentially written into the data memory of the RAM 20 together with the lap times data. 1st
S=1 in FIG. 1 shows the display state 7M at this time, and the total lap time calculated by Δ- is displayed on the upper display section 2. When 5 seconds have elapsed in this lap measurement mode, as described above, the 5 second lapse is detected in step T22 in FIG. 6, the lap measurement mode is canceled, and the mode is automatically switched to the original stopwatch measurement mode. However, before 5 seconds had passed after switching to lap measurement mode, the switch S3
When is operated again, this is detected in step T52 and the process proceeds to step T55, where the lap time at that time is stored in the RAM 20.

Therefore, each time the switch S3 is operated, the lap time at that time is determined and recorded.For example, as shown in FIG. The second lap time (1 minute 1 second 45) is recorded in the memory x3, the third lap time (58 seconds 97) is recorded in the data memory x4, and the number of times data is recorded correspondingly. In this case, the date data is recorded in correspondence with the finish time, so it is not recorded in correspondence with each lap time.

On the other hand, when the switch S2 is operated in the lap measurement mode, this is detected in two consecutive steps T34 in FIG. counter C
o is cleared and started. T=1 in FIG. 11 shows the display state in the lap stop mode. This lap stop +h
When 5 seconds have elapsed since the mode was switched, this is detected in step T25 of FIG. 6 described above, and the lap stop L: mode is automatically switched to the 3<top watch stop mode.

Stopwatch stop mode → reset mode When switch S3 is operated in stopwatch stop mode, this is detected in step T53 and the stopwatch stop mode is switched to reset mode (step 756), and The contents of the current start address register A are cleared, and the contents of the measurement register Yl are also cleared (step T
57).

Processing of switch S4> Every time switch S4 is operated, the flow shown in FIG. 9 is started, and in steps T61 to T64,
, N, W1, and P, the mode is determined.

In this case, reset mode (L=1), all data recall mode (N=1), stopwatch stop mode (W
The switch S4 operation is valid only when the current data recall mode (p=1) or current data recall mode (p=H) is set.

Reset mode: All data recall mode Assuming that the switch S4 is operated in the reset mode, the process proceeds to step T65, where the mode is changed.
From reset mode to all data recall mode (N=1)
can be switched to Therefore, to set the all data recall mode, it is only necessary to press switch S4 once in the reset mode of the stopwatch.When switched to the all data recall mode in this way, the pointer
0th order where the contents of n are cleared.

Data memory Xo = data memory addressed by the value of pointer Xn of X29, initially data memory Xo
It is checked whether measurement data is stored in the data memory xO (step T67).As shown in FIG. The contents will be displayed. In this case, of the data in the data memory XO, only the data marked 11 is initially displayed. That is, as shown in FIG. 12, when the switch S4 is pressed once from the clear mode of the stopwatch, data dated 11 (Friday, May 170, 1985) is displayed. In this case, as shown in FIG. 12, rROIJ is displayed in the middle row to indicate that the data is the first measurement data of the day. When the switch S4 is operated in this state, the process proceeds from step T62 to step T69 in this second operation of the switch S4. In other words, since the all data recall mode is currently set, the switch S4 is operated in this mode. Then, the presence or absence of measurement data is checked after pointer T68), therefore, in this case, as shown in FIG. 12, the finish time (19 minutes 28 seconds 36) is displayed at the bottom, and
In the middle row, a stop mark display is lit to clearly indicate that it is finish time, and the number of measurements rlJ indicating that it is the first measurement data is displayed. Thereafter, when the switch S4 is sequentially operated in the same manner, the value of the pointer xn is incremented by 1 each time the switch S4 is operated from the third time onwards, and as a result, the contents of the data memory are sequentially displayed. Therefore, in the third operation, the date data (Saturday, May 8, 1985) is displayed, and the rRO indicates that it is the first measurement data of that day.
IJ is displayed. Next, in the fourth operation, the finish time of "I" (20 minutes 13 seconds 02) will be displayed. In this case, as shown in Figure 4, that eye will display three lap times in addition to the finish time. If you take 5 times [1], the finish time will be displayed on the upper row, and the first lap time (1 minute O 1 second 32) will be displayed on the lower row.Similarly, the 6th and 7th lap time will be displayed on the lower row. 2 with the operation
[The 1st and 3rd lap times are displayed sequentially.

Therefore, in the eighth operation, "rRO2" indicating the next day's date data and the number of measurements of I) is displayed in the middle.

In this way, the measurement data in the RAM 20 is displayed in sequence in relation to the date data, and when the switch S4 is operated after the last measurement data is displayed, an empty area is detected (step T67). ), and with this empty area detection 1h, the mode counter B is set to (1) in steps T70 to T72.At first, the value of the mode counter B is "0", so in the next step T73, the value of the mode counter B is set to "1". (After 1 is incremented by +1, the best finish time is calculated and the result is displayed (step T7
4) That is, all the finish times recorded in the RAM 20 are compared and examined, the past best time is searched from the range, and this is displayed as the best time. In this case, as shown in FIG. 12, the rFINIsHJ
, rBEsTJ is displayed in the middle row, and the determined best finish time (19 minutes 28 seconds 36) is displayed in the lower row. Then, switch S4 is turned on once more.

Since the value of mode counter B is now rlJ, this is detected in step T71 and the process proceeds to step T75.
The value of mode counter B is increased by +18. Then, the worst finish time is determined and displayed (step T76). That is, all finish times are compared and examined, the lowest past time is searched among them, and this is displayed as the worst finish time. In this case, as shown in FIG. 12, rFINISHJ is displayed in the upper row, rWOR3 is displayed in the middle row, and the worst finish time (22 minutes 19 seconds 63) is displayed in the lower row. Furthermore, switch S4
Crop once. Now mode counter B's i1 is "2"
Therefore, this is detected in step T72, the value of mode counter B is incremented by 1 (step T77), and the average finish time is calculated and displayed (step T78), that is, all finish times are calculated and displayed. By adding the values and dividing the resulting value by the number of measurements, the average finish time in the past is determined and displayed. in this case,
As shown in Figure 7FS12, the top row shows rFINIsHJ, the middle row shows rAVEr, and the bottom row shows the average finish time (2
0 minute 18 seconds 15) is displayed.

” - All 1 records recorded in the data memory as mentioned above.
When the switch S4 is operated after the ta-data is displayed, the best finish time, worst finish time, and average finish time are sequentially switched and displayed each time the switch S4 is operated. Therefore, in the all data recall mode, the best finish time, worst finish time, and average finish time are determined and displayed, so that these pieces of information can be easily and accurately obtained. Then, when the switch S4 is pressed once more in the state 7fi where the average finish time is displayed, the process advances to step T79 and the mode is changed. That is, the contents of mode counter B are cleared, and the entire data recall mode returns to the reset mode.

Stopwatch stop mode = current data recall mode When switch S4 is pressed once in the stopwatch stop mode, step T63 detects the seventh event, and the process proceeds to step T80, changing from the stopwatch stop mode to the current data recall mode (P= 1), the value of the current start address register AO is transferred to the pointer Xn (step T81), and the contents of the data memory addressed by the value of the pointer Xn are read out and displayed. (Step T82). Fig. 13 shows an example of the display in this case. After the current date data is displayed with the first operation, the current finish time is displayed with the second operation, and the current date data is displayed with the third operation [1]. Lap times will be displayed sequentially in subsequent operations. That is, since the current data recall mode is set by the first operation of the switch S4, the process proceeds from step T64 to step T83 after the second operation, the value of the pointer xn is incremented by 1, and the value of this pointer is set to 1. It is checked whether the measurement data is stored in the data memory specified by (step T84). If the measurement data is stored, the process advances to step T82 and the contents are displayed, so switch S4 is pressed. is operated (the current measurement data will be displayed sequentially in +j. Then,
If the switch S4 is further operated while the last measurement data is being displayed, the process proceeds from step T84 to step T85, where it is checked whether the value of the mode counter B is rQJ. Initially, the value of mode counter B is "0"
Therefore, in the next step 788, the mode counter B's i1 is incremented by 1, and then the strap display is performed (
In step T89), the highest lap time among the lap times measured this time is displayed. Subsequently, when the switch S4 is activated once, the process proceeds from step T86 to step T90, and the value of the mode counter B is incremented by one. Then, the lowest lap time among the lap times measured this time is displayed as the worst lap time (step T91). Furthermore, when switch S4 is pressed once, the process advances from step T87 to step T92, and mode counter B ( 1 is incremented by 1.Then, the current average lap time is calculated from each lap time measured this time and displayed (step T93).Therefore, in the current data recall mode, the highest lap time and the lowest lap time of each lap time measured this time are displayed. Since the lap time and average lap time are calculated and displayed, these information can be easily and accurately known.And when the switch S4 is pressed once more while the average lap time is being displayed, Proceed to step T94,
In addition to clearing the contents of mode counter B, the current data recall mode is also switched to stopwatch stop mode.

As mentioned above, if you want to recall all the data, you can operate the switch S4 in the reset mode, and if you want to recall only the current data, you can operate the switch S4 in the stopwatch stop mode. This time, I will be able to recall the data. Therefore, if you want to know the finish time or lap time that was totaled this time when the current measurement is NIL, you can operate the switch S4 to enter the current data recall mode, so you can immediately know the current data. Kade S, effect (
This time, data recall will be more flexible in terms of i-wise and in line with actual usage.

Processing of switch S5> Every time switch S5 is operated, the flow shown in FIG. 10 is started, and in step T10I-T104, the mode is determined according to the contents of mode registers v, 0, R, and H. In this case, stopwatch measurement mode (V=
1) The switch S5 operation is valid only in the target time display mode (0=1), the lap display mode (H=1), and the distance difference display mode (U=1).

Stopwatch measurement mode = target time display mode Switch S5 is set to 1 in stopwatch measurement mode
If it is removed, step T101 to step T10
Proceeding to step 5, the mode is changed and the stopwatch measurement mode enters the target time display mode. and 1
In the next step Tl06, a preset target time is displayed. That is, among the target times preset in the target value setting memory PS, the latest target time and the next target time closest to the measured time are read out and the first target time is read out.
It is displayed as shown in Figure 1 0=1. Therefore, it becomes impossible to confirm the target time during the measurement operation. When the switch S5 is pressed once in this target time display mode, the process proceeds from step TlO2 to step T107, and the mode is changed. That is, the target time display mode is canceled and the original stopwatch measurement mode is restored. Therefore, if you want to know the target time, you can switch to the target time display mode, and if you want to know the lap time or measured time, you can cancel the target time display mode and switch to the stopwatch measurement mode.

Lap display mode 2 Time difference display mode When switch S5 is pressed once in the lap display mode, the process proceeds from step T103 to step T108, and the lap display mode is switched to the time difference display mode.

Then, in step T109, the time difference is displayed.The difference between the currently measured lap time and the latest 1 standard lap time set in advance is calculated, and this time difference is displayed on the L stage, and the latest The 11th station lap time is displayed on the dotted line (see Figure 11, 0 = 1). In this case, the time difference between the measured time and the 11th station time is determined by the plus/minus display 2-2 as a plus or minus time. Identification is displayed. Now, if you run faster than the 11 mark time, it will be a plus, and if you run slower, it will be a minus.

This allows you to know how much faster or slower you will be than your target time when you actually pass the checkpoint. If you change S, [If 1 mark time has not passed, ``1
The remaining time until the target time, [After the first target time has elapsed, overtime will be displayed, allowing you to manage your running pace. However, in such a time difference display mode,
When the switch S5 is pressed once, the process proceeds from step T104 to step Tll0, the mode is changed, the time difference display mode is canceled, and the original lap display mode is returned.

[Effects of the Invention] As explained in detail above, this invention stores and holds a plurality of pieces of measured time information, reads out all the time information when the stop/stop watch is in the clear state, and reads out the currently measured time information when the stop/stop watch is in the clear state. Since the time information is read out and displayed, when the current measurement is finished, the currently measured data can be immediately known with a simple operation, and data can be recalled efficiently and in line with the actual application. etc. effect.
