Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an alarm electronic timepiece, and more particularly to an alarm electronic timepiece that can generate an alarm sound at any desired time.

The subordinate alarm electronic clock is configured to drive an alarm generator at a time set by an alarm setting circuit.

Therefore, if you want to know what tone the alarm will sound, you have to set the alarm time at that time, which is troublesome for the purchaser, and from the seller's point of view, it is bad for sales promotions. Undesirable. Further, even when it is desired to use the alarm sound for purposes other than the original time notification function, it is virtually impossible to use the alarm sound with conventional alarm electronic watches. Therefore, the present invention makes it possible to drive an alarm generator at any desired time with a simple operation, to know the past color, and to make an alarm sound at a desired time for purposes other than time notification. This invention provides an alarm electronic timepiece that is extremely convenient for sellers and buyers, and will be described in detail below based on the illustrated embodiment.

Setting channels 7a, 7b, 7c of alarm setting circuit 7
When the alarm generation time, which is appropriately set, comes, a coincidence signal of logic "1" is output from each output terminal 9a, 9b, 9c of the coincidence detection circuit 9.

Now, at the time set in the setting channel 7a, if a coincidence signal is output from the output terminal 9a of the coincidence detection circuit 9, the output of the OR circuit 11a becomes logic "1" and the transmission gate 12a turns 〇N. , a 512Hz signal input to the transmission gate 12a is supplied to the alarm generator 15 via the OR circuit 14,
The alarm generator 16 is driven and generates an alarm sound.
Similarly, when a coincidence signal is output from the output terminal 9b of the coincidence detection circuit 9 at the time set in the setting channel 7b, the transmission gate 12b turns ○N, and 10
The alarm generator 5 is driven by the 24Hz signal, and
At the time set in the setting channel 7c, a coincidence signal is output from the output terminal 9c of the coincidence detection circuit 9, and when the transmission gate 12c is turned on, the alarm generator 15 is driven by the signal of day 2, 2048. At a store, etc., if you want to notify the buyer of the tone of the alarm sound, turn on the switch 16. In response, the waveform shaping circuit 19 outputs a logic "1" pulse, and the flip-flop circuit outputs a logic "1" pulse. The output logic of 23 is inverted and the Q output becomes logic "1".

As a result, the one-second pulse output from the frequency divider 2 passes through the AND circuit 24 and is input to the clock terminal CL of the ring counter 25. When the first pulse is input to the ring counter 25, the "1" output changes to logic "1", which is input to the control terminal of the transmission gate 12a via the OR circuit 11a, and the output is changed to the logic "1". Turn on.

As a result, the alarm generator 15 is driven by a 512Hz signal. When the second pulse is input to the ring counter 25 and the "2" output becomes logic "1", the transmission gate 12b turns ○N in response to this, and 1024
The alarm generator 15 is driven by the HZ signal.

When the third pulse is input to the ring counter 25 and its "3" output becomes logic "1", the transmission gate 1 2c turns ○N and the alarm generator 15 turns 204.
It is driven by the 2nd signal on the 8th.

The fourth pulse is input to the ring counter 25 and becomes “0”.
``When the output becomes logic ``1'', all transmission gates 12a, 12b, 12c are OFF,
The driving of the alarm generator 15 is stopped.

The above operation is performed by turning on the reset switch 20.
This continues cyclically until the flip-flop circuit 23 is reset and the Q output is made logic "0". In this way, in response to the ON operation of the switch 16, the alarm generator 15 can be driven at any desired time regardless of the alarm generation setting time, and the tone generated can be known. It is convenient for people to advertise. In addition, it is convenient for gamblers to know what tone of alarm the alarm will sound, and it is also convenient to use the alarm for purposes other than time notification. that's all,
Although the details of the alarm electronic timepiece according to the present invention have been described based on the illustrated embodiments, the present invention is not limited to the illustrated embodiments, and various changes and improvements can be made.

For example, although the illustrated embodiment shows a multi-type alarm electronic clock that can set a plurality of alarm occurrence times, the present invention is also applicable to a type that can set a single alarm occurrence time. . Furthermore, although the illustrated embodiment is configured to generate a plurality of alarm sounds in succession by operating a switch, a clock pulse is supplied to the ring counter each time the switch is operated, and an appropriate alarm sound is selected. You can also do this. Furthermore, if there is only one type of drive signal for the alarm generator, the ring counter is omitted and the output of the AND circuit 24 is supplied to the gate circuit 10. As described above, the alarm electronic timepiece according to the present invention is capable of generating an alarm sound by driving the alarm generator in response to the switch operation, regardless of the alarm generation time set by the alarm setting circuit. , it is very convenient for sellers to advertise, and
The user can easily recognize the alarm sound, and furthermore, the alarm sound can be used appropriately for purposes other than time notification, so that the intended purpose can be fully achieved and the practical effect is remarkable. There is.
