[Detailed description of the invention]

The present invention relates to an alarm data input device for a small electronic calculator with a clock function, etc. Recently, various electronic clocks with alarm functions and small electronic calculators with clock functions have been developed.
There are two types of alarm functions: a time alarm that sounds an alarm at a set time every day, and a date alarm that sounds an alarm at a set date and time every year. However, when two types of alarm functions, the time alarm and date alarm, are provided, separate alarm data must be input for each, which makes key operations complicated and the circuit configuration complicated. There was a drawback. The present invention has been made in view of the above circumstances, and its purpose is to enable the user to arbitrarily use one alarm function as either a time alarm or a date alarm, and to enable key operations for input. The purpose is to provide a simple alarm data input method. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a small electronic calculator with a clock function will be described below with reference to the drawings. 1 in the figure is the key input section, in addition to the numeric keypad and function keys normally provided on calculators,
Provide instructions for setting and displaying alarm data.
It consists of an AL key, a TM key for setting and displaying clock data, a PM key for specifying the afternoon, and a mode switch for setting the set mode and calculation mode when setting alarm and clock data.
This key operation signal from the key input section 1 is given to the key judgment section 2. The key judgment section 2 sends function data to the control section 3 based on the key operation signal, and calculates and stores numeric data to a numeric data storage section 4 and a numeric data storage section 5.
In addition to sending each operation signal of the TM key, AL key, and PM key to the numeric data control unit 6, the signal a, which is output as a single signal every time the numeric keypad is operated, is sent to the AND gate 7. Further, during the setting of the set mode, the signal b output as a binary logic level "1" is sent to the AND gate 7 and the one shot circuit 8, respectively. The numeric data storage section 5 has a storage capacity for 8 digits, and the numeric data input using the numeric keypad during setting of the set mode is sequentially shifted and stored starting from the first digit. The control section 3 executes various control operations based on the function data given from the key judgment section 2. That is, when the calculation mode is set, a control signal is sent out according to the operation of the function key for the numerical data stored in the calculation/storage section 4, and the calculation/storage section 4 performs calculations. is executed. Further, the calculation result data stored in the calculation/storage section 4 is sent to the display selection section 9. On the other hand, reference numeral 10 is an oscillator such as a crystal oscillator, which sends a reference frequency signal to the frequency divider 11. The output of this frequency divider 11 is sent to a time counting section 12, and the output of the time counting section 12 is sent to a date counting section 13. Thus, the time counting section 12 counts time data of hours and minutes, and the date counting section 13 counts date data of months and days. These time data and date data are sent to the display selection section 9, and are also provided to matching circuits 14 and 15, respectively. Further, the output signal of the one shot circuit 8 is given as a reset signal to the counter 16 consisting of 4 bits and the above-mentioned number data storage section 5. This counter 16 inputs the signal a through the AND gate 7 while the signal b is "1" and counts the number of inputs. Each bit output of the counter 16 is input to the decoder 17. Then, from this decoder 17, the count value of the counter 16 is "3".
and “4”, the signal c is sent via the OR gate 18.
is output as "1", and when the count values are "7" and "8", the signal d is output as "1" via the OR gate 19. These signals c and d are input to the numeral data control section 6. When the AL key operation signal is input while the signal c is being input, the numeric data control unit 6 uses the 4th to 1st digit numeric data stored in the numeric data storage unit 5 as time alarm data. The data is sent to the time storage section 20, and "0" is sent to the date storage section 21. Also, when the AL key operation signal is input while the signal d is being input, the 8th to 5th digit numeric data stored in the numeric data storage section 5 is sent to the time storage section 20 as time alarm data. , 4th to 1st digits are sent to the date storage unit 21 as date alarm data. Furthermore,
This numeric data control unit 6 inputs TM while inputting the signal d.
When a key operation signal is input, the 8th to 5th digit numeric data stored in the numeric data storage section 5 is sent to the time counter 12 as time preset data, and the 4th to 1st digits are The numerical data is sent to the date counting section 13 as date preset data. In the case described above, when the PM key is operated before the AL key and TM key are operated, the time alarm data and preset data are sent out as data with the afternoon flag added. The time alarm data stored in the time storage section 20 is sent to the display selection section 9, and the coincidence circuit 1 receives time data from the time counting section 12.
Sent to 4. Further, the date alarm data stored in the date storage section 21 is sent to the display selection section 9 as well as to the matching circuit 15 into which the date data from the date counting section 13 is input. Note that the alarm data of the date stored in the date storage section 21 is also given to the "0" judgment circuit 22. When the matching circuit 14 determines that the time data and the time alarm data match, the matching circuit 14 outputs a signal e as "1". Further, when the matching circuit 15 determines that the date data and the date alarm data match,
The matching circuit 15 outputs the signal f as "1". Furthermore, the signal g is output from the "0" judgment circuit 22 as "1" when the date alarm data is "0". Both the signal f and the signal g are applied to the AND gate 24 via the OR gate 23, and the signal e is applied to the AND gate 24. The output of this ANDGATE 24 is the output of the sound generation circuit 2.
5, and when the output of the AND gate 24 becomes "1", the sound generation circuit 25 generates an alarm sound. Further, while the numeric keypad and function keys are being operated in the key input section 1, the set number data or the calculation result data stored in the calculation/storage section 4 is selected by the control section 3 in the display selection section 9. and displayed on the display section 26. Further, by operating the TM key while setting the calculation mode, time data and date data are selected in the display selection section 9, and the current time and date are displayed on the display section 26. Similarly, alarm data of time and date is displayed on the display section 26 by operating the AL key. Next, the operation of this embodiment configured as above will be explained. First, when newly presetting the current time and date, set the mode switch to set mode. As a result, the key determination section 2 outputs the signal b, and the output from the one-shot circuit causes the numeric data storage section 5 and the counter 1 to
6 is reset. For example, September 1st at 11:00 p.m.
To preset 58 minutes, use the numeric keypad to

Enter only the numeric digits of the time and date in order, as shown in [Formula]. At this time, "11580901" is stored in the 8th to 1st digits of the numeric data storage section 5, and the counter 16 receives the signal a.
The number of inputs "8" is counted, and furthermore, the decoder 17 outputs a signal d via the OR gate 19. Next, when the TM key is operated, the above preset data is input into the time counter 12 and date counter 13. That is, since the TM key operation signal is input to the numeric data control unit 6 while the signal d is being input, the numeric data control unit 6 receives the numeric data in the 8th to 5th digits of the numeric data storage unit 5. ``1158'' is sent to the time counting section 12, and numeric data ``0901'' for the fourth to first digits is sent to the date counting section 13. In this case, since the PM key is being operated, a flag indicating afternoon is added to the time preset data sent to the time counting section 12. The time counting section 12 and date counting section 13 then start counting from the input preset data. If you want to set the alarm data of, for example, 1:15 a.m. as a time alarm for a small electronic calculator that counts the current time and date, first set it to the set mode.

Perform the key operation for [Formula]. That is, by setting to the set mode, signal b is output, AND gate 7 is opened, and counter 16 and number data storage section 5 are reset by the output of one shot circuit 8. and,
"00000115" is stored in the 8th to 1st digits of the numeric data storage section 5 based on the numeric data entered using the numeric keypad.
is stored, and the counter 16 counts the number of times "3" is entered. As a result, the signal c from the decoder 17
is output via the OR gate 18. The numeric data storage unit 6 inputs the signal c and the operation signal of the AL key, and stores the numbers 4 to 1 stored in the numeric data storage unit 5.
The digit data “0115” is sent to the time storage unit 20, and “0” is sent to the date storage unit 21. Therefore, as alarm data, only the alarm data of the time is stored in the time storage section 20, and when the time data of the time counting section 12 which is counting the current time and the alarm data of the above-mentioned time match, the coincidence circuit 1
When detected at 4, the signal e is output as "1". At this time, the "0" judgment circuit 22 indicates that the date data stored in the date storage section 21 is "0".
Therefore, the signal g is output to the AND gate 24 via the OR gate 23, and the output of the AND gate 24 becomes "1". Therefore, the sound generation circuit 25
An alarm sound is emitted. In addition, when setting the alarm data for December 15th, 1:09 p.m., as a date alarm, for example, after setting the set mode, Perform key operations. At this time, the stored content of the number data storage unit 5 becomes "01091215", and the number of numbers set on the counter 16 becomes "7". The numeric data control unit 6 generates numeric data “0109” for the 8th to 5th digits based on the signal d output from the decoder 17 and the AL key and PM key operation signals output from the key determination unit 2. The alarm data of the time with the afternoon flag added to the time is sent to the time storage section 20, and the number data "1215" in the fourth to first digits is sent to the date storage section 21 as the alarm data of the date. When the alarm data set as a date alarm and the contents of the time counter 12 and date counter 13 match each data of the time memory 12 and date memory 13, the matching circuits 14 and 15 send the signal e and the signal f is output, the output of the AND gate 24 becomes "1", and the sound generation circuit 25 generates sound. In this way, for one alarm function set by the AL key, if the number data is 3 or 4 digits, it will be used as a time alarm that sounds at the set time every day, and if the number data is 3 or 4 digits, Time can be set as a date alarm that sounds on a set date and time every year. Note that the number of digits of alarm data, the order of key operations, etc. in the above embodiment can be changed in various ways. In addition, in the above embodiment, when inputting a time alarm, the hour and minute data is entered using a 3-digit or 4-digit number, but for example, only minute data can be entered to generate an alarm sound at the set minute of each hour. Furthermore, a snooze function may be provided to make the sound emit at predetermined time intervals starting from the set time. Further, the alarm sound to be generated can be selected from various types such as a single sound, a melody sound, and a voice. Furthermore, in the above implementation, an example was explained in which one type of alarm function is provided that can be selected for the time alarm and the date alarm, but it is also possible to provide multiple types of alarm functions and make it possible to select the time alarm and the date alarm for each. good. As described in detail above, according to the present invention, the user can arbitrarily select the time alarm or date alarm function for one alarm function.
In addition, the date and time data can be automatically set by inputting alarm data using the numeric keypad and determining the number of digits entered at that time, so there is no need to switch between the time alarm or date alarm. This has practical effects such as simplifying the process.
