Description

[Detailed Description of the Invention] The present invention relates to an electronic device, such as an electronic watch, having a sound alarm function.

Recently, electronic clocks equipped with a sound alarm function have been developed.

For example, this type of noise control is equipped with a memory circuit in addition to the clock circuit that obtains the normal time, stores a desired time in this memory circuit, and when the normal time reaches the memorized time, it matches. The circuit is configured to output a matching signal and generate noise. However, after memorizing a desired time, there are times when I would like to know how many minutes left until the noise is generated. However, in the case where the noise is generated by the coincidence signal from the coincidence circuit as described above, the remaining time cannot be determined. I couldn't know. In addition to the above-mentioned function of making a noise at a desired time, there is also a function of storing the time as, for example, 2 o'clock in a memory circuit and making a noise after the elapse of 2 o'clock, or a function of making a noise at a time of 2 o'clock, for example. Various alarm functions can be considered, such as a function to store a noise in a memory circuit and make a noise every 2 alarms, and a function to make a noise every 2 alarms every hour by storing a predetermined number of alarms, for example, in a memory circuit. If all of the various noise functions mentioned above were to be provided, the circuit configuration including the control circuit would be extremely complicated because the configuration of each function would be different, and the operation for selecting the desired noise function would also be complicated. There were flaws. The present invention has been made in view of the above circumstances, and has an extremely simple circuit configuration by creating a circuit for a sound function that memorizes a desired time and eliminates noise at this time with a circuit configuration different from that of the conventional circuit. It can be equipped with many sound alarm functions, and the selection operation of the sound alarm function is easy.
To provide a new electronic device with a sound alarm function that can be applied to small electronic timepieces such as wristwatches. Hereinafter, an embodiment in which the present invention is applied to an electronic timepiece will be described with reference to the drawings.

The oscillation signal of the reference number of broken cycles output from the oscillation circuit 1 is frequency-divided to a predetermined frequency by the frequency divider circuit 2, and the pulse signal of the predetermined frequency output from the frequency divider circuit 2 is sent to the counter circuit 3.
sent to and counted. This counting circuit 3 outputs time data such as hours, minutes, seconds, months, and sleep time, and this time data is sent to the corresponding display element of the display section 5 via a display switching circuit 4, which will be described later. The signal is displayed digitally, for example, and is also sent to the input terminal 11 of the alarm control section 6, which will be described in detail later. Further, 7 is a setting storage circuit (hereinafter referred to as a storage circuit) in which the time or time is set, and the setting data of this storage circuit 7 is sent to the display switching circuit 4 and also to the alarm control section 6. It is also sent to the input terminal 12.
Further, 8 is a counting section in which time is set by output data from the output terminal 01 of the alarm control section 6 or a setting signal from the switch control section 9, which will be described later. 8, the pulse signal 1P/1M output from the counting circuit 3 every minute is sent from the output terminal 02 via the input terminal L of the alarm control section 6, and this pulse signal 1P/1M is sent from the output terminal 02 via the input terminal L of the alarm control section 6. It is sequentially divided by 1 (minus) 1 by 1M. The output data of the subtraction counter 8 is sent to the display switching circuit 4 as well as to the input terminal 13 of the alarm control section 6. The switch control section 9 includes a function selection switch section 10
A display switching signal is sent to the display switching circuit 4 in accordance with the signals output from the switch sections 11 and 12, and correction is made to the counting circuit 3, the memory circuit 7, and the subtraction counter 8! This is a decoder circuit that sends setting signals, and its detailed configuration is shown in FIG. 2 together with the function selection switch section 10 and switch sections 11 and 12. That is, the function selection switch unit 10 selects the contents by the switch S1 and the operation signal of the switch S1.
Shift register 13 into which one storage bit is shifted
and an OR circuit 14. In the initial state, the shift register 13 has the first bit set to "r".

The content is sequentially shifted by ゜゜1゛ to the 2nd bit, 3rd bit, and 4th bit of the shift register 13 each time the switch S1 is operated. , the contents of the fourth bit are output as the signal a1 signal b1 signal C1 signal d, respectively,
These signals are sent to the alarm control section 6. Also,
The switch section 11 is used to modify the contents of the time counting circuit 3 and to set the contents of the memory circuit 7 and subtraction counter 8. The operation signal of the switch section 11 is sent to the switch control section 9. It is being

The switch section 12 is used to selectively display any of the time data obtained by the counting circuit 3, the setting data of the memory circuit 7, and the output data of the subtraction counter 8 on the display section 5. Therefore, signals E and f are sent from the switch unit 12 to the switch control unit 9 in accordance with the operation thereof, and in normal times, the signal e is output, and as a result, the switch control unit 9 outputs a signal as a display command signal for the normal time. g is output. Furthermore, when an operation signal is applied to the switch unit 11 while the signal e is being output from the switch unit 12,
A time correction signal h is output, and the time is corrected by the counting circuit 3. This adjustment switch section 11 may be provided in a plural number instead of one, and each switch may be used to correct the hour digits, the minute digits, reset the seconds, etc. However, switch section 1
When the signal f is output from shift register 1,
If the content "1" exists in any of the first, third, and fourth bits of 3, this ゜゜1゛ signal is given to the switch control unit 9 via the OR circuit 14. Therefore, , a signal 1 is outputted from the switch control section 9 to the display switching circuit 4, which displays the contents of the storage circuit 7. Also, at this time, a signal j is outputted by the operation signal from the switch section 11. The time or time can be set in the memory circuit 7. Also, the shift register 13
When the content ゛“1” exists in the second bit of When an operation signal is applied, a signal 1 is output, and an arbitrary time can be set in the subtraction counter 8. Next, the detailed configuration of the display switching circuit 4 will be explained with reference to FIG.

Time data of the counting circuit 3, setting data of the memory circuit 7, and output data of the subtraction counter 8 are sent to the first input terminals of the AND circuits 19, 20, and 21, respectively. Further, the output signal of the AND circuit 18, the output signal of the AND circuit 17, and the output signal of the OR circuit 16 are sent to the second input terminals of the AND circuits 19, 20, and 21, respectively. Furthermore, the signal g1 signal 1 from the switch control section 9 is sent to the first input terminals of the AND circuits 18 and 17, respectively. Further, the operation signal of the switch 24 is inputted to the OR circuit 16 together with the signal k. This switch 24 is a remaining time display switch that is operated when you want to know the output data (remaining time) of the subtraction counter 8 whose contents are subtracted by one minute. , 17. Further, in FIG. 1, reference numeral 25 denotes a start switch, and the operation signal of this switch 25 is given to the input terminal 15 of the alarm control section 6.

The alarm control section 6 starts operating when the operation signal of the start switch 25 is applied, and selects different alarm functions depending on the signals A, b, c, and d given from the selection switch section 10. It controls the signals A,
The alarm function controlled by b, c, and d is as follows. Signal a: Sound alarm function that sounds at a set time.

Signal b: An alarm function that emits an alarm after a set time has elapsed.

Signal c: A sound alarm function that sounds a sound at each set time.

Signal d: An alarm function that makes an alarm at a set minute every hour.

Therefore, in any case, when the output data of the subtraction counter reaches ゜゜0゛2, the output terminal 03
A "゜0゛" signal is outputted from the terminal to drive the sound alarm device 26.

In the above configuration, the reference oscillation signal output from the oscillation circuit 1 is frequency-divided by the frequency divider circuit 2 and sent to the counter circuit 3 for counting.

Normally, the switch section 12 outputs the signal e, so the switch control section 9 outputs the signal g. This signal g is sent to the AND circuit 18 of the display switching circuit 4, and since the switch 24 is not operated, a 6°r1 signal is output from the AND circuit 18 and the AND circuit 19 is deregulated. Therefore, the time data from the counting circuit 3 is sent to the display unit 5 via the AND circuit 19 and the OR circuit 22, and the current time is displayed digitally. Further, when it is desired to correct the time of the counting circuit 3, when the switch section 11 is operated, a signal h is outputted and the correction is made. However, if you want to make the alarm sound at a desired time, for example, if the current time is 1:05 p.m. and you want to make the alarm sound at 3:00 p.m., first, by operating the switch section 12, A signal f is outputted from the switch section 12.

In addition, by operating the switch S1, the shift register 13
The signal a is output from the first bit of the signal a. Then, the signal 1 is output from the switch control section 9, the AND circuits 17 and 20 of the display switching circuit 4 are opened, and the setting data of the memory circuit 7 (at this point it is "0") is displayed on the display section 5. Then, by operating the switch section 11, the signal j is outputted from the switch control section 9 and stored in the memory circuit 7.
and sets the memory circuit 7 to 3:00 p.m. The setting data in the memory circuit 7 is sent to the display section 5 for display, and is also sent to the alarm control section 6. Next, when the start switch 25 is operated, as shown in FIG.
Perform step A. That is, the alarm control section 6 subtracts the normal time of the counting circuit 3 (1:05 gin) from the set time of the memory circuit 7 (3:00 pm), and the result (8 gins) is sent from the output terminal 01 to the subtraction counter 8. will be forwarded to. Next, the process moves to step B, where the content of the subtraction counter 8 is subtracted by 1 minute using the pulse signal 1P/1M output from the output dryer ρ2, and then step C
It is determined whether the content of the subtraction counter 8 is "O" or not. If it is not "0", the process returns to step B, the same operation as described above is performed, and the process proceeds to step C again. During this operation, if the user wants to know the remaining time until the alarm sounds, the switch 24 is operated. The AND circuit 21 is opened by the operation signal of the switch 24, and the output data of the subtraction counter 8 is sent to the display section 5 via the AND circuit 21 and the OR circuit 22, where it is displayed as the remaining time until the warning sound. When the output data of the subtraction counter 8 becomes "0", a signal is output from the output terminal 03 of the alarm control section 6, and the alarm device 26 makes an alarm (step D). If you want to get a warning sound after the second accident, after getting the signal f from the switch section 12, operate the switch S1 to get the signal b from the second bit of the shift register 13. By this operation, the signal from the switch control section 9 k is output, and the contents of the subtraction counter 8 (at this point, the value is "0") are displayed, and at the same time, the signal 1 is output by operating the switch section 11, and the subtraction counter 7 is set to "20". Then start switch 2
By operating 5, the steps shown in Figure 4 are started and steps B, C, and D are performed. In other words, the sound signal can be heard after two gins. For example, if it is desired to obtain a warning sound for each accident, the signal C is outputted from the shift register 13 by operating the switch S1, and the switch section 11
"15" is set in the memory circuit 7 by the operation. Thereafter, by operating the start switch 25, the step shown in FIG. 4C is started. That is, in step E, the value "15" set in the memory circuit 7 is input to the input terminal 1 of the alarm control section 6.
2, is set to the subtraction counter 8 via the output terminal 01.
Next, proceeding to steps F and G, the output terminal 02 of the alarm control section 6
The pulse signal 1P/1M output from the subtraction counter 8 is subtracted until the output data of the subtraction counter 8 becomes ゜゜0゛, and when the output data reaches ゛0゛, that is, after one error, a warning sound is made (Step H). At the same time, the process returns to step E and repeats the same operation, and a warning sound is generated for each error. Further, the fourth bit of the shift register 13 has the content "゜1".
'' exists, that is, when the signal d is being output, then every desired minute of the hour . For example, if the alarm is to be emitted at 2 pm every hour, the signals 1 and j are obtained from the switch control section 9 and "20" is set in the memory circuit 7.

Then, by operating the start switch 25, the step 2 in FIG. 4 is performed. In other words, step! In I,
It is detected that the time data of the counting circuit 3 is on the hour (4) 0 minutes), and upon this detection, the process advances to step J and the value "20" specified in the memory circuit 7 is transferred to the subtraction counter 8. do. Then, in steps K and L, the output data of the subtraction counter 8 is subtracted until it becomes ``0'', and when it becomes ``O'', a warning sound is made (step M). ), the same operation is repeated and a warning sound is made every hour.In this way, with the above configuration, the time is set and the warning sound is made when the time reaches this time. Since the alarm function is performed by the memory circuit 7 and the subtraction counter 8, there is no need to provide a one-stop circuit as in the conventional case. By using it as a memory circuit and a subtraction counter, a plurality of different alarm functions can be provided.

Further, in the alarm control circuit 6, steps B, F, and K are the same steps, steps C, G, and L are the same steps, and steps D, H, and Ml steps E and J are the same steps, respectively. Thus, four types of sound alarm functions can be controlled in only six steps including step A and step I, and the circuit becomes extremely simple. Furthermore, by operating the switch 24, it is possible to know the remaining time until the alarm sounds in all alarm functions,
Very convenient to use. In the above embodiment, the sound is generated by driving the sound alarm device 26, but if there is a notification means such as flashing a display, it is not necessary to generate the sound. In addition, the alarm function also has 4
It is not limited to the type, and for example, the sound may be sounded at a desired time on a desired month and day. Furthermore, in the above embodiments, the time and other settings in the memory circuit and subtraction counter are performed by operating a setting switch, but it goes without saying that the settings may also be made directly using, for example, a numeric keypad. As explained above, the present invention uses a memory circuit and a subtraction counter to generate a warning sound at a set time, so the circuit configuration is extremely simple, and therefore, it is possible to provide a wide variety of sound warning functions. This method has the advantage that it can be easily applied to small electronic timepieces such as wristwatches.

Furthermore, the switch operation for selecting one of the plurality of alarm functions is extremely simple, and this is also a great advantage. Note that the present invention is not limited to electronic watches, but can be applied to, for example, small electronic calculators having a timekeeping function, and can be applied in various ways without departing from the gist of the present invention.
