Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stopwatch device capable of setting a target time, and more particularly to a stopwatch device suitable for training capable of easily setting a plurality of target lap times.

[0002]

2. Description of the Related Art Conventionally, there is known a stopwatch device in which a target time is set in advance and an alarm sound is generated when the measured time from the start reaches the target time.

Such a stopwatch device is disclosed in Japanese Utility Model Publication No. 6-28718, column 2, line 3 to column 3, 8
The first line and FIG.

[0004]

However, in the past, for example, when setting a target time every 1 km in a 10 km run,
Set the first line (3 minutes, 20 seconds), and then the second line (6 minutes, 40 minutes).
Second), the split time was sequentially input and set like the third line (10:00), and 10 target time memories were required. The same process as the normal time adjustment has to be performed for the number of lines, and there is a problem that it takes time to set the target time. In addition, there is a problem that even if the set target time is partially changed, the change takes time. Furthermore, the target time is 10 for general commercial products.
There is a problem that it cannot handle because there is no memory when the number is large because the number is limited.

Therefore, the present invention solves such a problem, and sets the target time by inputting the lap time as the target time, not the split time, and by inputting only the change point of the lap time. An object of the present invention is to provide a stopwatch device that can be easily and easily operated.

Another object of the present invention is to provide a stopwatch device capable of preventing an erroneous target time from being input and easily confirming the set target time.

[0007]

A stopwatch device of the present invention comprises a time measuring means for measuring time information based on a start / stop command, a display means for displaying the time information obtained by the time measuring means, and a time measuring means. Lap switch means operated while the time is being measured by the means, lap counting means for counting the number of times the lap switch means has been operated, and a preset target lap time and a corresponding number of transparent laps. It has target information storage means for storing the number information and timer means for outputting to the notification means at a set time, and the lap counting means is the same as one of the plurality of lap numbers stored in the target information storage means. When it becomes, the corresponding target lap time is read out and the timer means is set.

In the present invention, the lap number corresponding to the target lap time at the change point is input, the target lap number is compared with the lap number under measurement, and when the same number is reached, the target lap time is updated. This is to reduce the user's input of the target time. Further, by inputting only the changed points, it is possible to handle a large number of lines with a small target time memory.

In this case, when the target lap time and the corresponding lap number information are input to the storage unit of the target information storage unit, the display unit can display whether or not the target information is stored in the next storage unit. desirable. Further, when the target lap time and the corresponding lap number information are read from the storage unit of the target information storage unit, it is desirable that the display unit displays whether or not the target information is stored in the storage unit next to the read information. .

This is because when the target lap time is input or the confirmation display is performed, the presence or absence of the continuous target lap time is displayed so that the information in the target time memory can be easily and easily confirmed even if the target time memory is large. It is something to do.

Further, the stopwatch device of the present invention is
A time measuring means for measuring time information based on a start / stop command, a display means for displaying the time information obtained by the time measuring means, a target for storing a preset target lap time and corresponding plural lap number information. An information storage means and an input means for setting and inputting a first target lap time in a first storage section of the target information storage means,
It is characterized in that the previous target lap time is input to the storage unit when the next storage unit input is performed.

In the present invention, when one target time is input to the target time memory and the next target time memory is displayed, the previously set target time is automatically set in the current target time memory. By doing so, it is possible to easily and easily input the target time.

The stopwatch device of the present invention is
Time measuring means for measuring time information based on start and stop commands, display means for displaying time information obtained by the time measuring means, and a target for storing a plurality of preset target lap times and corresponding lap number information An information storage means and an input means for setting and inputting a first target lap time in a first storage section of the target information storage means,
The present invention is characterized in that when the next storage unit is input, a specific value is added / subtracted from the previous target lap time and input to the storage unit.

In this case, it is desirable to have a plurality of specific values and select one of the specific values from the previously set target lap time.

In these inventions, when one target time is input to the target time memory and the next target time memory is displayed, a specific value is automatically added to or subtracted from the previously set target time, and the current target is set. By setting the time in the time memory, it is possible to easily and easily input the target time such as a built-up run.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The stopwatch device of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a stopwatch device of the present invention. In the figure, a stopwatch device includes a measurement time, a RAM 1 for a measurement data memory and a target time memory, and an RO for a program.
M2, a counter for counting measurement time, an input / output port, an arithmetic unit 3 including an LCD (display) driver and an arithmetic circuit, a display unit 4 for displaying measurement data, an oscillator 5 made of crystal, an oscillator Frequency dividing circuit 6 for oscillating and dividing 5 to generate a reference signal necessary for measurement, measurement switch 7 connected to the input port of arithmetic unit 3, arithmetic unit 3
It is composed of a sounding unit 8 which is connected to the output port of and outputs an alarm.

The arithmetic unit 3 has a central processing unit (CPU), and a program for controlling the central processing unit is written in the ROM 2. In addition, RAM1, ROM2,
The arithmetic unit 3 and the frequency dividing circuit 6 are composed of a one-chip microcomputer 9. The measurement switch 7 is composed of five switches 7A to 7E.

The main functions of the five switches (only those related to the present invention) will be described. The switch 7C is a mode select switch for selecting some modes in the stopwatch device. Of these, particularly relevant to the present invention are a stopwatch mode for performing a time measurement operation and a target mode for inputting / confirming display of a target lap time (in addition to this, for displaying stored measurement data). There are recall modes, etc.). The mode is cyclically switched each time the switch 7C is pressed. In the stopwatch mode, the switch 7A has a start / lap / finish function, and the switch 7B has an end function of ending measurement. In the target mode, the switch 7A changes the target value or turns on the target operation.
The switch 7B is used to switch ON / OFF or change the number of laps to be corrected or displayed for confirmation, and the switch 7B is used to select the time digit or the like of the target value. Further, the switch 7C is used to select a memory for storing a target lap time in the target mode. The switch 7D is an adjustment switch for instructing whether or not to correct the set time or the like in the target mode, and to confirm the correction if the correction is made. The switch 7E is a light switch for illuminating the display 4, and is not directly related to the operation of each mode.

Next, the time measuring procedure of the stopwatch device of the present invention will be described. The switch 7C is used to set the stopwatch mode. For the time measurement, the reference signal from the frequency dividing circuit 6 is used to start the measurement of the measurement counter of the RAM 1 in the arithmetic unit 3 based on the start command of the switch 7A, and the measurement status is displayed on the display 4 every moment. Then, during the time measurement, by the lap command of the switch 7A,
The measurement data is stored in the RAM 1 and the measurement status is displayed on the display 4. Switch 7A at the finish point
The finish command stores the measurement data in the RAM 1 and displays the measurement status on the display 4. That is, the lap command and the finish command differ only in the names, and the substantial measurement operation is the same. As a result, the time measurement is continued and displayed on the display 4 even after the finish command (it is not distinguished at this point whether it is the lap command or the finish command). In this state, when the end command by the operation of the switch 7B is received, the data measured at the finish point is read from the RAM 1 and displayed on the display 4 together with the "FINISH" icon. That is, the switch 7B has nothing to do with time measurement, and the latest data is the final measurement data and the finish data.

According to the above-mentioned configuration, since the switch 7A is the only switch for measuring the time such as the start, lap and finish, it is possible to reduce erroneous operations.

FIG. 2 is a front external view of the stopwatch device of the present invention. In this embodiment, all of the segments of the display 4 are lit. In the upper part, the lap time is displayed in 7 digits from 1 hour unit to 1/100 second unit, and further, the number of laps is displayed in 2 digits. On the other hand, the integrated time (split time) is displayed as a 7-digit number in the lower row, like the lap time. "FINISH"
Is controlled so that it is turned on when the finish data is displayed. Mode display icon (ST.W, RECALL, TA
RGET) is displayed at the bottom. In addition, "ST.W" is the stopwatch mode, "RECALL" is the recall mode (the measurement data that has already been measured is read and displayed), "TARGET" is the target mode, and the target time is set and confirmed. It sometimes lights up.

FIG. 3 is a main block diagram of the RAM 1. The memory address is selected by PAGE, HIGH, LOW. Address names are on the right for ease of explanation. The accumulated data address has accumulated data from the start (0:02
Minutes 34 seconds 56) is stored. The number of lap measurements (01) by the switch 7A is stored in the lap value data address. The number of lap measurements starts from "01". However, when it is displayed on the display 4, it is displayed as minus one. That is, the display when the lap measurement has never been performed is "00". Calculation WORK1 and W
The ORK2 address is an area used for calculating the lap time from the split time stored in the measurement memory. It is also used for other work. Pace memo 1 address is the first target time (03
Minutes 20 seconds) and the number of laps (01) are stored.
Further, the LOW = 7 address has a flag indicating whether to operate the set target time. "0" is non-operational "OF"
The operation becomes “ON” at F ”and“ 1. ”The second target time (03 minutes 10 seconds) and the number of laps (08) are stored in the pace memo 2 address. The pace memo 3 address is the third. The target time (03 minutes 00 seconds) and the number of laps (09) are stored, and the pace memo 4 address stores the fourth target time (02 minutes 50 seconds) and the number of laps (10). The target time is not stored in the 5th address (00 minutes 00 seconds), and the number of laps (0F) indicating that the target time is not stored is set as described above. You can set the time.The currently used timer value (03 minutes 20 seconds) is stored in the timer memo address.Timer 1 and 2 addresses are for notifying that the target time has come. It is between, timer 1 is 00 minutes 4
5 seconds 5 and timer 2 is inactive. When the LOW = 7 of the timer 1 and 2 addresses is "1", it is operating, and "0"
At the time of, it is a flag indicating non-operation. The time measurement data is stored in the remaining addresses.

FIG. 4 is a flow chart for explaining the timer processing operation for notifying that the target time of the stopwatch device of the present invention has been reached in the stopwatch mode. Note that the switch configuration and the display are described with respect to those shown in FIG. Hereinafter, first, individual steps and their operations will be described in a general manner along the flow.

In the figure, step 21 is switch 7A.
It is "measurement start?" For determining whether or not is pressed to enter the measurement state (start). Step 22 is pace memo 1
"Target ON?" To judge whether to execute the set target time operation by the address flag (LOW = 7)
It is. Step 23 is "setting value plural?" For judging whether the target time is set in addition to the pace memo 1 address, and if plural, set "S flag = 1" in step 24. If there is not a plurality, S flag = 0. Step 25 is "timer memo setting, timer 1 setting" for setting the target time stored in the pace memo 1 address to the timer memo address and the timer 1 address and starting the timer of the timer 1 address. Step 26 is "LAP measurement?" For determining whether the switch 7A is pressed during the measurement and the lap measurement is performed. Step 27 is "measurement complete?" For determining whether the switch 7B is pressed during the measurement to terminate the measurement. In step 28, the data value of the integrated data address at the time of measurement is stored in the designated RAM 1 and the value of the wrap value data address is increased by 1
Then, in step 24, it is determined whether the S flag is set "S flag = 1?". Step 29 is "value same?" For judging whether the lap value data and the number of set paces of pace memos 1 to 5 are the same. Step 30 is "timer memo ← pace memo" for setting pace memo data of the same value in the timer memo. Step 31 is "Timer 1 in operation?" For judging whether or not the timer 1 is in operation, which informs the sounding unit 8 that the target time has come. Step 32 is "timer 1 ← timer memo" for setting the data of the timer memo address to the timer 1 address. Step 33 informs the sounding unit 8 that the target time has come. It is determined whether the timer 2 is in operation "Timer 2"
in action? In step 34, the data of the timer memo address is set in the timer 2 address "timer 2 ←
"Timer memo", that is, the target time is timer 1
Is not operating, it is set to timer 1 and timer 1
Is set and the timer 2 is not operating, the timer 2 is set. Step 35 is "end".

The counting up of the measurement counter during measurement and the timer processing (S20) are periodically executed by the interrupt function of the one-chip microcomputer 9. Also,
Although not shown, the determination of whether or not the timers 1 and 2 have ended (00 minutes 00 seconds) is performed by the same interrupt processing as in the conventional case,
When finished, the sounding unit 8 gives a notification. As in the conventional case, it is desirable that the sound is made from 3 seconds before the end.

Next, the actual flow of the flowchart of FIG. 4 will be described. Before the measurement, the target time and the corresponding number of laps are input, and the target time operation is set to "ON" (this operation, that is, the operation method in the target mode will be described in detail later). The target time is 10km running 10 laps of the same 1km as above.
Run at 3'20 'pace from lap 1 to 7 and 3 at lap 8
It is a so-called built-up run that runs 10 minutes, 3 minutes 00 seconds on the 9th lap, and 2 minutes 50 seconds on the final 10th lap.

When the switch 7A (START) is pushed at the same time as the start notification such as a pistol start sound, S2
1, S22, S23 and S25 are executed. That is,
Data (03 minutes 20 seconds) of S flag = 0 and pace memo 1 address is set to the timer memo address and the timer 1 address, and the measurement of the integrated data address and the timer 1 address is started. S2 until lap measurement is done
6 and S27 are repeated. During this time, it is detected whether the addresses of the timer 1 and the timer 2 are in operation and become "00 minutes 00 seconds 0". On the first lap, when timer 1 ends, it sounds that the target time has come. When the first lap measurement is performed, RA in which the integrated data is designated by S28
The data of the wrap value data address stored in M1 is incremented by 1 and S29 is executed. In this case, the data of the lap value data address is "2", there is no same value as the set lap number of the pace memo 1 address to the pace memo 5 address, and the process proceeds from S29 to S31. And S3
The data of the timer memo address is set in the non-operation timer by 1 and S32. For example, if the start point is passed earlier than the target time on the first lap, since timer 1 is still operating, 03 minutes and 20 seconds are set in the timer 2 address by S33 and S34, and timer 2 is started. That is, even if the user starts earlier or later than the target time, the target time for the second lap starts with the start point (measurement point) as a reference, so that it is possible to try the target lap time again.

The same operation is repeated from the second lap (1 km to 2 km) to the seventh lap (6 km to 7 km), and the target time is reported as "03 minutes 20 seconds".

When the lap measurement at the 7 km point is performed, S
By 28, the data of the wrap value data address is incremented by 1 from "7" and becomes "8". In this case, the data of the lap value data address and the set lap number of the pace memo 2 address have the same value. Therefore, the data (03 minutes 10 seconds) of the pace memo 2 address is set to the timer memo address in S30. If timer 1 is inactive, S
32 sets "03 minutes 10 seconds" to the timer 1 address. That is, the target time for the eighth lap (7 km to 8 km) is changed to 03 minutes 10 seconds.

When the lap measurement at the 8 km point is performed, S
By 28, the data of the wrap value data address is incremented by 1 from "8" and becomes "9". In this case, the data of the lap value data address and the set lap number of the pace memo 3 address have the same value. Therefore, in S30, the data of the pace memo 3 address (03 minutes 00 seconds) is set to the timer memo address. That is, the target time for the ninth lap (8 km to 9 km) is 03:00.

When the lap measurement at the 9 km point is performed, S
By 28, the data of the wrap value data address is incremented by 1 from "9" and becomes "10". In this case, the data of the lap value data address and the set lap number of the pace memo 4 address have the same value. Therefore, in S30, the data (02 minutes 50 seconds) of the pace memo 4 address is set to the timer memo address. That is, 10th lap (9k
The target time from m to 10 km) is 02 minutes and 50 seconds.

According to the above-described structure, in the build-up run in which the first half is performed at a constant pace and the second half is gradually increased in pace, the build-up run is performed with a small number of target times to accommodate a large number of runs. You can

FIG. 5 is a flow chart for explaining the target time setting processing operation of the stopwatch device of the present invention. The mode is shown as a target, the switch configuration is shown in FIG. 2, and the RAM 1 is shown in FIG. Hereinafter, first, individual steps and their operations will be described in a general manner along the flow.

S41 is "SW7D ON?" Which determines whether the switch 7D is pressed. S42 is the sub counter SC
Is "0", and when it is "0", "end" of S43
Then, the timer setting is completed. The sub counter is "
When it is 0 ", the pace memo 1 address is displayed in an uncorrected state."
When "1", the pace memo 1 address is corrected, when "2", the pace memo 2 address is corrected, when "3", the pace memo 3 address is corrected, and when "4", the pace memo 4 address is corrected. In the case of, the address of the pace memo 5 is corrected, and in S44, it is determined whether the sub counter SC is "0".
S45 resets the sub-counter SC "SC =
0 ". S46 sets the sub-counter SC to 1" SC =
1 ". S47 is the same as the conventional switch 7B (SELEC
T) and switch 7A (SET), which determines whether there is a correction by the select-set method "time correction?" If there is a time correction, the corresponding digit is corrected by 1 by "correction" in S48. S49 is "SW7C ON?" Which determines whether the switch 7C is pressed. In S50, the sub-counter SC is incremented by "SC ← + 1". S51
Determines whether the sub-counter SC has reached "6""S"
C = 6? "S52 sets the sub-counter SC to 1"
C = 1 ". In S53, the data obtained by adding 1 to the target time set in S48 and the set lap number is set in the pace memo designated by the sub-counter SC" previous set value storage ".
It is. In step S54, it is determined whether the target time is set in the pace memo designated by the next sub-counter value "Target continue?". In S55, the continuation mark is lit "continuation mark lit". In S56, the continuation mark is turned off "continuation mark is extinguished". S57 displays the necessary data on the display 4 "
"Display".

Next, the actual flow of the flowchart of FIG. 5 will be described with reference to FIG. 3 as an example.

At this time, the mode select switch 7
It is assumed that the target mode has been set in advance by operating c. Before setting the lap time, it is assumed that the previous target time is set to the pace memo 1, 2 and 3 addresses and the sub counter SC = 0. The display at this time is shown in FIG. Pace memo 1
Has been set to "03 minutes 15 seconds", the left center shows the number of set laps "1" (it must be "1" at the beginning), "OFF" in the upper row, and the right-pointing triangle mark in the right center The continuation mark of is displayed. The continuation mark indicates that the target time is still set at least for the pace memo 2 address. “OFF” indicates that the target time notification operation is not performed even if the time measurement is started in the stopwatch mode.
This is the initial display state when the target mode is entered.

When the switch 7D is pressed in this state, S4
As a result of 6, the sub-counter SC = 1 and the pace memo 1 address is corrected. Then, it is determined in S54 that there is data in the pace memo 2 address, and S55
The continuation mark is lit by, and "OFF" by S57.
Flashes to indicate that it can be corrected, and "1" indicating that it is the pace memo 1 address display is displayed in the upper right part. The display at this time is shown in FIG. FIG. 6B
In the figure, "OFF" is surrounded by a dotted line, which means that "OFF" is blinkingly displayed.

When switch 7A is pressed in this state, "O"
The display will change to "n". "OFF" and "On" will change alternately. Further, by operating the switch 7B, the correction digit will change cyclically in the order of second-minute-On / OFF-second, and the selected position will be changed. The number of laps set is fixed at "1" and cannot be corrected, but this is because "1" is always used at the beginning no matter how many laps are set. When the switch 7A is pressed five times while operating the 7B to set the second correction state, the result is as shown in FIG. 6C, and the setting operation of the target lap time for the first lap is completed.

When the switch 7C is pressed here, S50
The sub-counter SC becomes 2 by S53, and the target lap time "03:20" and the number of paces "2" by S53.
(1 is added to the previously set lap number 1) is set in the pace memo 2 address. The display at this time is shown in FIG. After this, "On / OFF" is not displayed,
This is because if the "On / OFF" display is set first, it cannot be set again thereafter. By operating switch 7B, the corrected digit is the number of laps-second-minute-
It will change in the order of the number of laps. Previous state (Fig. 6
Although the number of laps could not be corrected in (a) to (c), it can be corrected after that. This is one of the features of the present invention, and when the same target lap time is used for a plurality of lap measurements, the target lap time should not be stored for each number of laps but should be stored in one storage unit (pace memo). It is used to get things done. In this state, if the number of laps is "8" and the target time is "03 minutes 10 seconds" by operating the switches 7A and 7B, FIG.
As shown in (e), the setting for the eighth round is completed. In other words, the same target lap time "0" from the 1st lap to the 7th lap
3 minutes and 20 seconds "has been set.

When the switch 7C is pressed here, S50
The sub-counter SC = 3, and the target lap time "03 minutes 10 seconds" and the number of paces "9" are set in S53.
(Previous set lap number 8 plus 1) is set to the pace memo 3 address. The corrected digit by the switch 7B changes in the order of lap number-second-minute-lap number. In this state, operate the switch 7A to set the target lap time
When the time is set to "03:00", the result is as shown in Fig. 6 (f), and the setting for the ninth lap is completed. At this time, since the pace memo 4 address does not contain the previously set data, S
The continuation mark is turned off by 56.

When the switch 7C is pressed here, S50
The sub-counter SC is set to 4 by S53, and the target lap time is "03 minutes 00 seconds" and the pace is "10" by S53.
Is set to the pace memo 4 address. Switch 7B
The number of laps corrected by changes in the order of lap number-second-minute-lap number. When the target lap time is set to "02 minutes 50 seconds" by operating the switch 7A in this state, FIG. 6 (g)
The setting for the 10th lap is completed. Now that the target lap time and the corresponding lap number have been set, pressing the switch 7D causes the sub-counter SC to enter an uncorrected state of "0" in S45, and the timer setting ends (shown in FIG. 6 (h). Change to fixed state).

Although not described in the embodiment, for example, the pace memo data designated by simultaneous pressing of the switches 7A and 7B is reset (00 minutes 00 seconds), or the switch 7 is pressed.
If the simultaneous pressing of A and 7B continues for 4 seconds or more, all the pace memo data are reset so that the operation becomes easier.

According to the above-mentioned structure, only the change point of the target lap time needs to be set, and the input operation can be reduced. Further, it is only necessary to input the lap time itself, and there is no need to convert it into the split time as in the conventional case. Further, the target time memory can be handled with a small number. Further, when the target lap time is set, whether or not the next target time memory is used is displayed with a continuation mark, so that the wrong target lap time can be set.

FIG. 7 is another flow chart for explaining the target lap time setting processing operation of the stopwatch device of the present invention. In FIG. 7, S53 is deleted from FIG. 5 and S60 and S61 are added. The other flow is the same as that in FIG. 5, and therefore, the steps similar to those in FIG. 5 are omitted. In S60, 10 seconds is subtracted from the target time set in S48 "minus 10 seconds from previously set value". S61 is "calculated value storage" for setting the data obtained by adding 1 to the calculation result of S60 and the previously set lap number in the pace memo designated by the sub counter SC.

Next, the actual flow of the flowchart of FIG. 7 will be described with reference to FIG. 3 as an example. For example, when the switch 7C is pressed in the state where the target time setting for the first lap in FIG. 6C is completed, the sub-counter SC = 2 is set in S50,
From S60 from the last set time (03:20)
"10 seconds" is automatically subtracted, and "03 minutes 1" by S61.
0 second "and pace number" 2 "(previous lap number 1 plus 1) are set in the pace memo 2 address.

According to the above-mentioned configuration, particularly in setting the built-up run, the number of switch input operations is reduced, and the target setting operation can be facilitated. Further, since it may be considered that the build-up run is not assumed, for example, S60 may be set to "add 10 seconds" instead of "subtract 10 seconds".

FIG. 8 is another flow chart for explaining the target lap time setting processing operation of the stopwatch device of the present invention. In FIG. 8, S53 is deleted from FIG. 5, and S61, S70, S71, S72, S73 and S74 are deleted.
5 is added, and the other flow is the same as that in FIG. 5, and therefore the steps similar to those in FIG. 5 are omitted. In S70, it is determined whether the previous target lap time set in S48 is within 1 minute or not "within 1 minute?", And in S71, 5 seconds is subtracted from the previously set time ".
-5 seconds from the last set value ", S72 determines whether the last target time is within 1 to 2 minutes" 2
Within minutes? ", S73 is" minus 10 seconds from the previous set value "for subtracting 10 seconds from the previous set time, and S74 is" minus 20 seconds from the previous set value "for subtracting 20 seconds from the previous set time. S61 is It is a "calculated value storage" in which data obtained by adding 1 to the calculation result and the previously set lap number is set in the pace memo designated by the sub counter SC.

Next, the actual flow of the flowchart of FIG. 8 will be described with reference to FIG. 3 as an example. For example, when the switch 7C is pressed in the state where the target time setting for the first round in FIG. 6C is completed, the sub-counter SC = 2 is set in S50.
By S70 and S72, the previously set time (03 minutes 20
Second) is determined to be 2 minutes or more, "20 seconds" is subtracted from the previous set time in S74, and "03 minutes 00 seconds" and the pace number "2" (previous lap number plus 1) are added to the pace memo 2 address in S61. Is set to. That is, the subtraction amount is automatically adjusted according to the target lap time.

According to the above-mentioned configuration, particularly in the setting of built-up running, the number of switch input operations is reduced, the target setting operation can be facilitated, and the more realistic time setting is possible. Become. Also in this example,
There is a case where built-up running is not assumed, so instead of "5 seconds, 10 seconds, 20 seconds subtraction", "5 seconds,
Add 10 seconds, 20 seconds "S71, S73, S
You may make it set 74.

FIG. 9 is a diagram showing a display state when the target lap time is confirmed (at the time of reading). This is performed by pressing the switch 7A when the target mode is uncorrected (that is, the switch 7C is operated to enter the target mode but the switch 7D is not operated). FIG.
(A) is “03 minutes 20 seconds” stored in the pace memo 1 address in FIG. 3, the set lap number is “1”, and “0” is shown in the upper row.
“ON”, a continuation mark is displayed. The continuation mark processing is the same as S54, S55 and S56 in FIG. 5, and in this case, the pace memo 2 address is set. In this state, the switch 7A is pressed. 9B, the pace memo 2 address is displayed, and when the switch 7A is pressed in this state, the pace memo 3 address is displayed, and when the switch 7A is pressed, the pace memo 3 address is displayed in FIG.
The pace memo 4 address is displayed. When the switch 7A is pressed in this state, the display returns to the pace memo 1 address display of FIG. 9 (a). It is not displayed when the target value is not set like the pace memo 5 address.

According to the above-mentioned configuration, it becomes clear at the time of displaying a certain target lap time whether the next target is set, and the target lap time can be easily confirmed.

[0053]

As described above, the stopwatch device of the present invention has the following effects.

According to the invention described in claim 1, since the lap number corresponding to the target lap time is set,
Only the change point of the target setting needs to be input, and the target can be set with less input and the target setting memory.

According to the second and third aspects of the present invention, since the presence / absence of continuation of the next target setting is displayed, it is possible to prevent erroneous setting.

According to the invention as set forth in claim 4, since the previous set value is automatically set to the present set value, the input work from the switch is reduced and the target can be easily set.

According to the fifth and sixth aspects of the present invention, since the previous set value is added / subtracted to automatically become the set value of this time, the input from the switch can be easily reduced especially in the build-up run. Can set goals.
