Abstract

PURPOSE:To manage time, by comparing a display time of a pointer with a time data stored to output an alarm when they coincide. CONSTITUTION:A switch control circuit 19 latches a time data into a latch circuit 14 from a game time memory circuit 11. When a start button is depressed, the circuit 19 outputs a time pulse CK1 to a step motor driving circuit 20 and a time counter 6 from a gate 3 to start the counting of time. With the suspension of a game, when a stop button is depressed, the circuit 19 closes the gate 3 to block the inputting of the pulse CK1 to the circuit 20, the counter 6 and a pointer counter 7b. When the button is depressed with the resumption of the game, the circuit 19 opens the gate 3 to restart operations of the step motor and the counter 6 to further advance the turn of the pointer and counter counts kept at the time of the suspension of the game. As time gets very close to a set value, a buzzer B generates a prealarm with an alarm circuit 18 and when the time counted with the counter 6 coincides with a data of the circuit 14, a main alarm is generated by a signal of a coincidence detection circuit 13 through the circuit 18 thereby enabling accurate management of time.

In addition, the reference numeral 20 in the figure is a step motor drive circuit, and a step motor M for moving the hands is connected to the hands 31 to 33 so as to match the number of clock pulses CKI and fast forward pulses GK2 inputted via the pulse separation circuit 40. □, M-1, M3 @
It is something that is driven.

Next, the operation of the device configured in this way will be explained.

[Stopwatch Mode] When the stopwatch mode is selected by the rotation cell 37 and the start/stop button 34 is pressed, the switch control circuit 19 outputs a start signal, opens the clock pulse gate 3, and starts the rotation from the frequency divider circuit 2. The clock pulse CK1u is output to the clock counter 6 and the step motor drive circuit 20. As a result, the clock counter 6 counts the clock pulses CK1u and starts time measurement, and the step motor drive circuit 20 receives the clock pulses CKI and drives each step motor M□, M
2. Activate M3 to rotate the pointers 31 to 33, and the pointer counter 7b of the lap time release/zero return circuit 7 outputs the clock pulse C to the step motors M1 to M3.
Monitor the movement M of the pointer by counting K1%.

When the start/stop button 34 is pressed to end the time measurement,
The switch control circuit 19 outputs a stop signal to close the clock pulse gate 3, and the step motor drive circuit 19,
The clock pulse CKI to the clock counter 6 is blocked, the rotation of the step motors M□, M2, and M3 and the counting operation of the counter 6 are stopped, and the elapsed time from the start is displayed by the hands 31 to 33. .

When the reset button 36 is pressed to clear the display, the switch control circuit 19 outputs a reset signal and sends a fast forward pulse CK2V from the reset gate 4 to the step motor drive circuit 2.
0 and is output to the pointer counter 7b. As a result, the step motors M1, M2, and M3 rotate at high speed to rotate the hands 31 to 33 toward their respective zero positions, and the hand counter 7b counts the fast forward pulse GK2u.

When the pointer reaches the zero position in this way, the pointer counter 7b outputs a return-to-zero detection signal and closes the reset gate 5, blocking 032% of the fast-forward pulse to the step motor drive circuit 7 and returning the pointer to zero. Stop at zero position. After this,
The switch control circuit 19 outputs a counter reset signal to return all counters 6.7b to zero in preparation for the next measurement.

Furthermore, when the lap button 35 is pressed during timing, the switch control circuit 19 outputs a lap time display signal, closes the lap time display gate 8, and sets the clock to the lap time release/return circuit 7 and the step motor drive circuit 20. hour pulse C
Block input of K1.

On the other hand, the clock counter 6 continues counting the clock pulses CKI. As a result, the hands 31 to 33 stop the timekeeping operation and display the lap time while the timekeeping data from the start of timekeeping is stored in the time counter 6.

In this state, if you press the start/stop button 34,
A lap time display release signal and a time display signal from the switch control circuit 19 are outputted to the lap time display gate 8.
and open lap time gate 9. As a result, the pointer counter 7b of the lap time release/zero return circuit 7 calculates the count value at the start of the lap time display operation by integrating the clock pulse CKI and fast forward pulse CK2 input via the pulse separation circuit 7a. Also, step motor M1,
M2 and M3 start high-speed feeding of pointer 3], 32.33. In this way, when the counted content of the pointer counter 7b matches the counted content of the clock counter 6, that is, the measured time, the -number output circuit 7c outputs a matching signal, closes the lap time display cancellation gate 9, and closes the lap time display canceling gate 9. The sending pulse CK2 is prevented from being input to the lap time release/zero return circuit 7 and the step motor drive circuit 20. As a result, the guideline 31~
33 displays the elapsed time that matches the elapsed time from the start of time measurement. Needless to say, during fast forwarding, the step motor drive circuit 20 is connected to the separation circuit 40a.
Since the clock pulse CK1 and the fast-forward pulse CK2 are input through the fast-forward operation, there is no loss time caused by the fast-forward operation.

[Timer mode] When one of the sports in the timer mode, for example, soccer, is selected by the rotation cell 37, the switch control circuit 19
outputs the game time setting signal and stores the game time memory circuit 11.
The game time data of the soccer game is read from the area, for example, area Ia, and is latched by the latch circuit 14.

When the start/stop button 34 is pressed at the same time as the start of the match after completing such preparations, the switch control circuit 19 is activated.
outputs a start signal and sends a clock pulse CK from the gate 3 to the step motor drive circuit 20 and the clock counter 6.
I! Output.

As a result, the hands 31 to 33 rotate in accordance with the passage of time, and the clock counter 6 starts measuring time. In such a state, when the start/stop button 34 is pressed due to an interruption of the match, the switch control circuit 19 closes the clock gate 3 and sends information to the step motor drive circuit 20, clock counter 6, and pointer counter 7b. The input of the clock pulse CKI is blocked to interrupt the clock operation and counting operation.

When the start/stop button 34 is pressed to restart the match, the switch control circuit 19 outputs a signal to open the clock gate 3, and steps up by adding 1 to the amount of hand rotation and each counter count value before the interruption. The operations of the motors M1, M2 and the clock counter 6 are restarted.

From now on, each time the game is interrupted, the clocking operation is interrupted, loss time is excluded, and the effective time is accumulated.

When the timing of the clock counter 6 advances to near the set game time, the timing contents of the clock counter 6 match the data of the preliminary alarm time setting circuit 17a, and a signal is output from the coincidence detection circuit 17b. As a result, the alarm circuit 18 is activated and the buzzer B emits a preliminary alarm sound to notify that the end of the game time is near. Further time passes and the clock counter 6
When the time measurement contents match the data of the latch circuit 14, -
The multiple building output circuit 13 outputs a signal to issue the main alarm.

If you press the reset button 36 at this point, the fast forward pulse CK2
The pointer is returned to the zero position and the time counter 6 is returned to zero. At the same time, the switch control circuit 9 outputs a signal to cause the latch circuit 14 to latch the break time stored in the area Ib of the match time memory circuit 1, and the clocking of the break time begins.

When the break time has elapsed close to the set time, the timing contents of the clock counter 6 match the data of the preliminary alarm time setting circuit 17a, and a preliminary alarm is issued. Then, when the set rest time expires, the main alarm is issued because the time measured by the clock counter 6 matches the rest time data.

If you press the reset button 36 at this point, the fast forward pulse GK2
The pointer is returned to the zero position, and the time counter 6 returns to zero. At the same time, the switch control circuit 19 outputs a signal to cause the latch circuit 14 to latch the second half game time stored in the area Ic of the match time storage circuit 11, and to measure the time by the same process as the first half game time.

In addition, if a situation arises that requires interruption of the break time,
By pressing the start/stop button 34, the timekeeping operation is interrupted, and by pressing the start/stop button 34 again, the timekeeping operation can be restarted to manage the net rest time.

[Match time setting mode] When the slide switch 38 on the back of the case 30 is moved to the match time setting mode, and then the target competition is selected by rotating the rotation cell 37, the switch control circuit 14 moves the rotation cell 37 to the game time setting mode. A display switching pulse is output to the readout control circuit 12 each time the switch passes through the switch contacts 25 to 29. The address designating circuit 12b moves the address and waits every time a display switching pulse is input.

On the other hand, the timer circuit 12a repeats the timing operation from the beginning every time the display switching pulse is input. When the rotation cell 37 is aligned with the target competition and no new switching pulse is output and the time measurement reaches the predetermined time, the timer circuit 12a outputs a signal that is set in the address designation circuit 12b. The address signal of the area l11a is output to the game time storage circuit 11. At the same time, the timer circuit 12a
The signal from
K2 @ time counter 6 and step motor Ml, N/
L2 and M3 are outputted to fast-forward the pointer, and the clock counter 6 starts counting the fast-forward pulse CK2.

In this way, when the timing content of the clock counter 6 matches the data of the latch circuit 14, the -number output circuit 13 outputs a signal to close the readout gate 5 and close the hands 31 to 33.
The rotating operation of the clock and the timing operation of the clock counter 6 are stopped, and the time data of the selected area l11a of the match time storage circuit 11 is displayed using the hands 31 to 33.

This makes it possible to prevent excessive hand movements based on time difference data stored in intermediate areas, which not only shortens the time required to switch to another time, but also minimizes the number of fast-forward hand movement pulses necessary to conserve battery life. Reduce wasteful consumption.

In this state, if you press the start/stop button 34,
The switch control circuit 19 outputs a signal every time the button is pressed, and the time setting circuit 15 that receives this outputs a number of fast forward pulses GK2 corresponding to, for example, one minute of hand movement. This fast-forward pulse GK2 is input to the clock counter 6 and the step motor drive circuit 20, and the time measurement contents and the hands 31 to 33 are inputted to the clock counter 6 and the step motor drive circuit 20.
Have the driver change the instructions in one minute. At the same time, this fast-forward pulse CK2 is input to the game time storage circuit 8 via the write circuit 6, and the stored data in the selected area is changed in accordance with the number of pulses.

After pressing the start/stop button 34 until the desired time is displayed, press the reset button 36.
The switch control circuit 14 outputs a reset signal to set the pointer and each counter to zero, and at the same time, the game time storage circuit 8 stores the time displayed by the pointers 31 to 33 in the selection area. At this point, by setting the break time setting mode using the slide switch 38 and following the same steps as described above, the time to be set can be stored in the selected storage area nla.

When the storage of each time is completed, the slide switch 38
By returning to measurement mode, you can manage the game time using the data you have just set.

In the above-described embodiment, the changeover from game time to rest time timing may be performed automatically, or the changeover may be made by pressing the start/stop button 34.

(Effects) As described above, according to the present invention, while the reference clock pulse is measured in response to the operation of the start/stop button, the time is displayed by the hand in accordance with the content of the time measurement, and the reset button is pressed. It is equipped with a display means that returns to the zero position by fast forwarding when operated, and a time memory circuit means for storing arbitrary time data, and when the time data of the time memory circuit means are compared with the display time of the pointer and the time data of the time memory circuit means match. Since it is equipped with an alarm means that outputs an alarm, it is possible to display the time in an analog manner using a pointer, while also realizing time management using a timer function, making it possible to operate in the same way as a familiar analog display stopwatch. It can be used intuitively to manage time for all sports.
