Description

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

When an alarm is set and the alarm is activated, the conventional method is as follows: 1. When the alarm goes off in the middle of the night and the user does not know the position of the push button, the user is often inconvenienced.

In this sense, there is a need for a mechanism that can stop the noise with a simple operation. On the other hand, portable electronic watches equipped with a touch switch mechanism are already on the market. When you press a touch switch, a light emitting diode lights up and displays the time. By using this touch switch mechanism, it is possible to easily input a switch, but the drawback of this mechanism is that the switch must be input at times other than when inputting a touch. Therefore, it is conceivable to provide an operation switch member to control the switch input of the touch switch mechanism, but in the case of a switch that lights up a display, this would negate the advantage of the touch switch in that switch input can be easily performed. Therefore, in the present invention, in order to take advantage of the fact that switch input can be easily performed, this touch switch is used as a switch to stop the alarm sounding, and also as a switch for operating other functions, and at the same time, it is used as a switch to activate other functions. Considering the configuration that prevented it from working in the past, we pursued the most practical way to use the touch switch mechanism. Therefore, the purpose of the present invention is to provide the following electronic timepiece with an alarm.

This will be explained below with reference to the drawings.

FIG. 1 is a block diagram of an electronic timepiece with an alarm according to the present invention.

2 is a reference signal source, 4 is a frequency dividing circuit, 6 is a minute counter, and 8 is an hour counter, and 6 and 8 constitute a time measuring circuit. 10 is an alarm minute counter, 12 is an alarm time counter, and 10 and 12 constitute an alarm setting circuit. 14 is a coincidence detection circuit, 16 is a control circuit, 18 is an alarm warning device, and 19 is a touch switch mechanism.

When the time and alarm select switch 44 is manually operated and the switch 44 is closed, a signal is input to the flip-flop 46, and the output line 48 of the flip-flop 46 becomes H level. Therefore, the output line 52 via the OR gate 50 becomes H level, and by opening and closing the switch 44, a signal is input to the shift register 54, causing the shift register 54 to change. When the output line 56 of the shift register 54 becomes H level, the AND gate 28 and the AND gate 3
0 opens. Similarly, the output line 6 of the shift register 54
4 becomes H level, AND gate 36 and AND gate 38 are opened. In this selected state, if you want to adjust the time, press the time set switch 2.
When 2 is opened and closed, a signal indicating the number of openings and closings is sent to line 26 via a flip-flop 24 for eliminating chattering.
is transmitted to AND gates 28 and 36, and corrects minute counter 6 and hour counter 8 via OR gates 32 and 40, respectively. On the other hand, when setting the alarm time, the touch switch terminals 70 and 72 are made conductive by touching them with the human body in this selected state, and the signal of this contact circuit is transmitted via the touch switch circuit 20 to the gate circuit 7.
The signal is transmitted to the AND gate 76 of No. 4. Since the output line 78 of the coincidence detection circuit 14 is normally at the L level, the AND gate 76 is open in the normal state, so the signal indicating the number of contacts is sent to the AND gates 30 and 38 via the line 80. The times of the alarm minute counter 10 and alarm hour counter 12 are set. In this way, when the times held by the hour counter 8 and the minute counter 6 match the set alarm time, the AND gates 82 and 8 of the match detection circuit 14
The output lines 86 and 88 of the AND gate 90 become H level, and the output line 78 of the AND gate 90 also becomes H level. Since the one input line 94 of the AND gate 92 is normally at H level, when the output line 78 goes to H level, the output line 96 of this AND gate 92 also goes to H level.
The alarm warning device 18 is operated to notify an alarm warning. On the other hand, when the output line 78 becomes H level, the AND gate 98 of the gate circuit 74 is opened and the AND gate 76 is closed, and at this time, the touch switch mechanism 19 functions as an alarm stop switch. That is, when the touch switch terminals 70 and 72 are made conductive by touching them with the human body, the output line 100 of the switch circuit 20 becomes H level, and
The output line 102 of the AND gate 98 also becomes H level, and this signal is passed through the AND gate 103.
The signal is transmitted to the flip-flop 104, and the flip-flop output line 106 is fixed at the H level. At this time, the line 94 passing through the inverter 108 goes from H to L level, so the AND gate 92 is closed and the line 94 goes from H to L level.
6 becomes L level and the alarm alarm stops sounding. Since the AND gate 103 is closed when the line 94 becomes L, the touch switch terminals 70, 7
Even if 2 is brought into contact conduction, the output contents of flip-flop 104 do not change. With the above configuration, the alarm can be stopped from sounding by an extremely simple operation of contacting and connecting the touch switch terminals 70 and 72. When a table clock is made with this clock configuration, by arranging a large touch switch terminal on the top, side, or front of the clock, it can quickly stop ringing even in the dark. On the other hand, even when used as a portable watch, by arranging the touch switch terminal on the exterior surface, you can easily silence the alarm even when your hands are occupied. Moreover, in the case of portable watches, the touch switch mechanism used to work due to contact continuity of the touch switch terminal with other conductors, but as in the embodiment of the present invention, the touch switch mechanism functions to generate alarm warning signals and select signals. Devices that are configured and used to operate under the control of a switch compensate for this drawback.

As described above, the electronic watch with alarm according to the present invention has great practical effects.
