Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hand movement display type electronic watch equipped with a timer function.

In recent years, digital electronic watches that use liquid crystal display cells, etc., have become more and more equipped with various functions such as alarm functions, timer functions, stopwatch functions, and calculation functions due to the remarkable improvement in display technology and IC technology. As they have become rapidly popular as a commercial product, it has become increasingly desirable to add the above-mentioned functions to analog electronic watches, that is, electronic watches with a hand movement display. However, compared to digital electronic watches, electronic watches with a hand movement display operate the hands using a mechanical mechanism to display the time. It has been considered to provide a display board and a mechanical structure, or to provide a switching mechanism that allows the timer time to be displayed using the time display pointer. However, these had many problems in commercialization, such as the complicated mechanisms that made them extremely expensive and the watches themselves thick.

Therefore, the present invention is provided with a memory counter that can set the timer time using an external operating member, and a timer counter that counts the timer time. It has become possible to add a timer function to electronic watches. Furthermore, in addition to the normal timer function, the electronic timepiece of the present invention has a repeat operation function for repeatedly using the timer function, and has a notification sound caused by the normal timer function and a notification sound caused by the repeat function. By making the difference, it is clearly identified whether the state is a normal timer function state or a repeat operation function state. Furthermore, by configuring the circuit so that the repeat operation can be set only during the timer operation after starting the timer time, a clear operation method using the repeat operation is possible.

Embodiments of the present invention will be described in detail below with reference to the drawings.

33, 34, 35, 36, and 37 are resistors for stabilizing the signals in the OFF state of each of the switches.
24, 25, 26, 27 are the minute digit switches, 10
These are waveform shaping circuits that receive operation signals for the minute digit switch, start switch, and repeat switch.

Next, the operation of the hand movement display type timepiece equipped with a timer function in the above configuration will be explained.

A reference signal generated by a reference oscillator 1 is converted into a one-second signal by a frequency dividing circuit 2, and the one-second signal is sent to a drive circuit 4 that drives a pulse motor 5 to drive a hand movement display device. Also, the 1 second signal is the minute counter 3.
minute counter 3 outputs a 1 minute signal.
It is sent to AND gate 6.

Next, the timer function will be explained. When the set mode switch 28 is first turned on, the operating signal changes from logic level "0" to "1".
While turning on the AND gates 38 and 39,
The operating signal is a so-called rising edge signal, and the OS circuit 11 generates a pulse at the output Q. The output pulse of the OS circuit 11 resets the memory counter 9 and SRFF 15, and further OR
SRFF 12 is also reset through gate 14.
Next, when the 10-minute digit switch 30 is operated twice to write the desired timer time (for example, 23 minutes), the operation signal is transmitted to the waveform shaping circuit 25.
is sent to the 10-minute memory 9b of the memory counter 9 through the AND gate 39, and the data is sent to the 10-minute memory 9b of the memory counter 9.
b stores the information value 2, which is further sent to the buzzer drive circuit 22 via the OR gate 21 and output to the buzzer 23.
emits two beeps. Similarly, by operating the minute digit switch 29 three times, the minute memory 9a is
The information value 3 is stored in , and the buzzer 23 emits three notification sounds. When the desired timer time writing operation is completed, the set mode switch 28 is turned off.

Next, when the start switch 31 is operated to start the timer function, the operation signal passes through the waveform shaping circuit 26 to set the SRFF 12, and further passes through the OR gate 10 to reset the timer counter 7 and minute counter 3. do. At the same time, SRFF12 is set, so the output Q becomes logic level “1” and AND gates 6, 13, and 17 are set.
Set to ON state. In this state, minute counter 3
The one-minute signal from the 1-minute signal passes through the AND gate 6 and is sent to the timer counter 7, which performs a timing operation. Here, both the output signals of the timer counter 7 and the memory counter 9 are sent to the coincidence circuit 8, and when the two output signals match, the coincidence circuit 8 sets the output Q of the coincidence signal to the "1" level.

Now, the timing operation of timer counter 7 is progressing, and 23
After the minute elapses, the matching circuit 8 outputs a matching signal.
It is sent to AND gates 16 and 17. At this time, the SRFF15 is in a reset state, and the SRFF15 is in a reset state.
The output Q of 5 is at logic level "0" and logic level "1", and AND gate 17 is ON and AND gate 16 is OFF. Therefore, the coincidence signal is
The signal passes through the AND gate 17, the OR gate 21, and the buzzer drive circuit 22, causing the buzzer 23 to emit an alarm sound. After one minute or more has passed, the match signal becomes logic level "0" and the output of the AND gate 17 becomes
Since this is a falling signal, the OS circuit 20 outputs a pulse. The output pulse of the OS circuit 20 is OR
The SRFF 12 is reset through the gate 14, and a series of timer operations are completed.

Next, a method for repeatedly operating the timer function will be explained.

In the above explanation of the timer function, the procedure for setting the timer time and starting the timer function is performed in exactly the same manner as described above, and after the timer counter 7 starts counting, the timer time (23 minutes in this case) is set. ) If the repeat switch 32 is operated before the time has been counted up to .), the operation signal passes through the waveform shaping circuit 27 and the AND gate 13 and sets the display SRFF 15. Therefore, the corresponding SRFF
The output Q of 15 becomes a logic level "1" and becomes a logic level "0", and the AND gate 16 becomes ON and the AND gate 17 becomes OFF. Then, when the timer counter 7 counts 23 minutes as in the timer function description above, the coincidence signal from the coincidence circuit 8 is sent to the AND gates 16 and 17, and then sent to the OS circuit 19 via the AND gate 16. At this time, OS circuit 1
Since the input signal 9 rises, a 3-second output signal is output to the output Q, and the buzzer 23 emits a 3-second alarm via the OR gate 21 and the buzzer drive circuit 22. That is, by emitting a notification sound different from the notification sound during the normal timer, it is possible to make the user aware that the repeat operation is set. Furthermore, the output signal of the OS circuit 19 is
The signal is sent to the OS circuit 18, and when the output signal for 3 seconds ends, the OS circuit 18 outputs a pulse and resets the timer counter 7. and again 23
After the minute has elapsed, the matching circuit 8 outputs a matching signal and emits an alarm for 3 seconds. That is,
In the above configuration, SRFF15 and AND gate 16,
17 selects and controls repeat and non-repeat of the timer. The repeat operation works in the manner described above, and is repeated until the set mode switch 28 is operated.

This concludes the explanation of the operation in FIG. 1. In this embodiment, the alarm sound is set for 1 minute during the normal timer function and 3 seconds during the repeat operation, but the duration of this alarm sound is not particularly limited. It is sufficient that the normal timer operation and the repeat operation can be distinguished, and for example, instead of the OS circuit 19, modulation means such as tone color or volume may be used. Further, the repeat switch can also be used as a switch for other functions when the clock is not operating as a timer function.

As described above, in the present invention, the hand movement display type electronic watch can be equipped with a timer function and a repeat function, and in order to clearly distinguish between the normal timer function state and the timer repeat function state, the timer function and the timer repeat function state can be clearly distinguished. Because the buzzer sound was made different,
Both functions can be easily distinguished without providing any special identification display means. Furthermore, since the start button of the timer is operated and the repeat switch is input only while the timer is operating, the operation method for setting the repeat operation can be made clear. Therefore, since the user only has to switch between the two functions as needed, the versatility of analog watches can be dramatically increased, and it is possible to provide an electronic watch with a hand movement display that has strong product appeal. It is.
