Description

[Detailed explanation of the idea] The present invention relates to an electronic watch.

Most conventional electronic clocks set the time by continuously adding the time by continuously pressing the time adjustment switch.
According to this method, there is not much of a problem when the number of set times is small or when the setting frequency is low, but if the number of time settings increases due to an increase in the number of alarms, etc., the setting time increases and the operation becomes complicated. This makes the operation more troublesome. Furthermore, in the case of on-off timers and the like, there is also a demand for constantly confirming the set time.

The present invention was developed in view of the above, and by using a display device equipped with a bar graph display, it is possible to input frequently changing times such as alarm times continuously and in a short time, thereby reducing the complexity of inputting. It is an object of the present invention to provide an electronic timepiece that can display input timer time continuously or intermittently, and can be checked at all times.

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

Reference numeral 15 denotes a time display section, which constitutes a normal electronic timepiece. Also, 16 is SCAN/
STOP control circuit, 17 is AND gate, 1
8 is a counter for counting 15 pulses, 19 is a timer counter, 20 is a comparison circuit, 21 is an output circuit, 2
2 is an ON/OFF control circuit, 23 is a shift register, 24 is an address counter, 25 is a time memory, and 26 is an OR gate, which controls the bar graph display and interacts with a normal digital electronic clock. It consists of

The SCAN/STOP control circuit 16 is
When the SCAN/STOP key is pressed once, the signals a and b become "1", and when the key is pressed twice, the signals a and b return to "0". The ON/OFF control circuit 22 outputs signals c, d, e, and f. Signal c changes to "1" when the ON/OFF key is pressed once, and returns to "0" when pressed twice. The signal d is
When the ON/OFF key is pressed twice, the contents of the shift register 23 are decremented by 1. Signal e is ON/OFF
This is a counting pulse signal that is output every time a key is pressed. The signal f is a write pulse signal that is output every time the ON/OFF key is pressed. While the signal b is "1", the AND gate 17 passes a pulse signal higher than 1 second from the frequency dividing circuit 11, for example, a signal g of 256 Hz, and outputs the signal g to the counter 18 for counting 15 pulses.
The gate is closed by the signal h from. The 15-pulse counting counter 18 counts the output pulses of the AND gate 17, and when the count reaches 15, outputs h and i, and repeats this every time the 1-second signal j is output. The timer counter 19 corresponds to the bar graph display segment. The shift register 23 also corresponds to the bar graph display segment, and the bar graph display section 14 selectively displays the contents of either the timer counter 19 or the shift register 23.

Next, a method of setting the time of the on-off timer and its display will be explained. First, when the timer counter 19 is cleared using the H/P key, the bar graph display will display 12:00 AM for the purpose of cursor display. This is a state in which only the leftmost segment is displayed. At this time, only the first bit of the shift register 23 is "1" and the remaining bits are "0". Here, when the SCAN/STOP key is pressed, the signal b becomes "1", the AND gate 17 is opened, and a high frequency pulse of, for example, 256 Hz is output every second. The counter 18 counts this high-frequency pulse train, and when the count reaches 15, it outputs a shift pulse i, and at the same time outputs a shift pulse i to the AND gate 17 using a signal h.
Close. The counter circuit 18 closes the AND gate until the next triggering 1-second signal comes, and when the 1-second signal comes, opens the gate again and repeats the above operation. The reason why 15 pulses are used here is because the time interval of bar graph display is set in 15 minute increments. In this way, the contents of the timer counter 19 become 12:15 AM due to one shift pulse signal i.
In the shift register 23, the leftmost bit "1" is moved one bit to the right, and therefore the bar graph display section also displays only the second segment from the left end, representing 12:15 AM. Thereafter, in the same manner, the bit "1" of the shift register 23 and the bar graph display will sequentially move to the right every 15 minutes, and the timer counter 19 will also move to the right.
It is counted up every 15 minutes.

Next, let's consider a case where, for example, a timer is turned on from 1:00 AM to 2:00 AM. If you press the ON/OFF key when the bar graph display segment displays 1:00 AM, that is, when the fourth segment from the left is displayed,
The signal c of the ON/OFF control circuit 22 becomes "1", the input of the shift register 23 becomes "1" via the OR gate 26, and the signal is shifted by 1 bit each time a shift pulse arrives every 15 minutes. Since c continues to be "1", all segments after the 1:00 AM segment are lit up. In this way, as shown in Figure 3, when the display reaches 2:00 AM, the second
When you press the ON/OFF key, signal c becomes "0", but if this continues, segment P in Figure 3 will be displayed, and one segment more will be displayed after the cursor disappears, so For correction, signal d is output to reduce the number of segments by one.

On the other hand, the output signal f of the ON/OFF control circuit 22 is a write pulse for the time memory 25, and each time the ON/OFF key is pressed, the current time of the counter 19 is written to the RAM. Therefore,
In the above example, 1:00 AM ON is written first, and when the ON/OFF key is pressed for the second time,
OFF at 2:00 AM is written. Also, ON/
The output signal e of the OFF control circuit 22 is a count pulse of the memory address counter 24, and each time the ON/OFF key is pressed, the address counter 24 is incremented by 1 and the addresses of the memory 25 are sequentially switched. Note that the scan operation is AM,
Run PM twice or SCAN again
End by pressing the STOP key. At the same time as the scan operation ends, the contents of the address counter 24 are reset and return to the initial address.

The comparison circuit 20 compares the timer time input as described above with the electronic clock in real time, and outputs an output K when they match. At this time, if the most significant bit of the memory 25 is "1", the output circuit 21 outputs A=1, and if it is "0", outputs A=0, so this is used as an on-off control signal or an alarm signal. It can be used as Also,
The output of the comparison circuit 20 is introduced into the address counter 24, the address counter 24 is counted up, and the next set time is read out and transferred to the counter 19.

According to the present invention, the alarm time can be set in a short time with simple operations, and the set time of the on-off timer can be confirmed with a bar graph. You can get a watch.
