Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a calendar display device that clearly displays a date value corresponding to a specific day of the week out of date values in which numbers 1 to 31 are arranged.

General digital electronic watches divide and count the reference oscillation signal and display seconds, minutes, hours, date, and so on.
Although it digitally displays the date of the month, it is being considered to display a calendar in addition to the time and date so that it can be used when planning various dates and plans. Such conventional calendar display devices display the calendar corresponding to the current month by clearly displaying the date numbers corresponding to a specific day of the week, such as Sunday, from other date numbers. It is something. By the way, when using a calendar, we often plan various dates and schedules while looking not only at the current month's calendar, but also at the next month's calendar, or the calendar for two or three months ahead. It would be extremely inconvenient and impractical to be able to display only the calendar for the following month.

This invention was made in view of the above-mentioned circumstances, and its purpose is to effectively display a calendar for not only the current month but also a desired month, and to display a calendar when the current month is updated. An object of the present invention is to provide a highly practical calendar display device that can effectively control calendar display.

Hereinafter, the present invention will be explained in detail based on an embodiment shown in the drawings. In FIG. 1, reference numeral 1 represents an oscillation circuit that generates a reference signal. The output signal from this oscillation circuit 1 is frequency-divided by a frequency divider circuit 2 and given to a counter circuit 3. This counting circuit 3 includes a time counting circuit 3a that counts each time unit of seconds, minutes, and hours, a day counting circuit 3b and a day counting circuit 3c that count in response to signals from the time counting circuit 3a, and a day counting circuit 3c that counts in response to a signal from the time counting circuit 3a. It is equipped with a month counting circuit 3d that receives and counts signals from the circuit 3c. Each of these pieces of clock information is given to the display device 5 via the calendar control circuit 4. This display device 5 has a specific day of the week display section 5a in which seven English letters "SU" indicating a specific day of the week, for example Sunday, are arranged in a horizontal row, and a date display section 5a in which numbers 1 to 31 are arranged in five rows and seven columns. It consists of a numerical value section 5b and a month display section 5c. The above display device 5
is designed to turn on or off in accordance with the turning on of switch _S1 . That is, each time switch _S1 is turned on, one pulse signal is output from the one-shot circuit 6 and the binary flip-flop is turned on. 7, and the output from the Q side of flip-flop 7 is applied to the date numerical part 5.
b as a display command and also as a gate signal to AND circuits 22 and 23, which will be described later, so that the information from the AND circuits 22 and 23 is given to and displayed on the specific day of the week display section 5a and month display section 5c, respectively. It is something. Thus, the signal from the one-shot circuit 6 is also applied to AND circuits 8 and 9 connected to the output terminal of the flip-flop 7 and the Q output terminal. Therefore,
When the output of the flip-flop 7 is switched from to Q, the AND circuit 8 is opened and the output signal from the AND circuit 8 is supplied to the calendar control circuit 4.
In the calendar control circuit 4, the switch S ₁
The output signal from the AND circuit 8 accompanying the operation is sent as a drive signal to the specific day of the week column detection means 10, and when this drive signal is given, the day of the week counting circuit 3 is activated in the specific day of the week column detection means 10.
Based on the information from b and the day counting circuit 3c, information for specifying the column to be displayed on the specific day of the week display section 5a is output, and the information is written into the specific day of the week column storage means 11. This specific day of the week column storage means 11 is a combination of, for example, a well-known presettable up counter and a pulse generation circuit that generates a number of pulses corresponding to the number of additions of the addition signal supplied from the specific day of the week column information correction means 18, which will be described later. Consisted of. FIG. 2 shows the details of the specific day of the week column detection means 10, in which the day, month, and
An AND circuit decoder is configured by a combination of seven signal lines corresponding to Tuesday...Saturday and signal lines corresponding to seven columns of date numbers from the day counting circuit 3c, and a signal is sent from the AND circuit 8. A signal is output to one of the signal lines L ₁ to _{L o+1 ,} and one of the signals M ₁ , _{M 2 . 7} are respectively sent to the specific day of the week column storage means 11 as set signals of "0", "1", . . . "6". The numerical information set in the specific day of the week column storage means 11 is sent to the specific day of the week display section 5a via the AND circuit 22, and the "SU" display corresponding to the numerical value is displayed, for example, "1". ”, 2, 9, 16, 23,
The "SU" display placed above the 30th is displayed to display the calendar for the current month.

On the other hand, 12 is a month-end adjustment circuit, and this month-end adjustment circuit 12 includes a day counting circuit 3c and a monthly counting circuit 3c.
Information from d is now provided. In the month-end adjustment circuit 12, for example, in the case of a large month, when the day count value exceeds "31", a signal is given to the month count circuit 3d to increment by 1, and the day count circuit 3c is set to 1. In addition, in the case of a small month, when the day count value exceeds "30", a signal is given to the month counting circuit 3d to increment by +1, and a month change signal is given to the day counting circuit 3c to set it to 1. It is set as. Also, this month-end adjustment circuit 1
2, a drive signal is also given to a display month automatic update control means 13, which will be described later, just before outputting the month change signal. Note that this month-end adjustment circuit can be easily constructed by adding a delay circuit to the well-known month-end adjustment circuit.

The month information of the month counting circuit 3d is written into the display month storage means 15 via an AND circuit 14 to which a signal is applied from the AND circuit 8. This display month storage means 15 is for storing display month information of a calendar display, and is constituted by, for example, a well-known presettable up-down counter. Therefore, the month information written in the display month storage means 15 is further sent to the month display section 5c via the AND circuit 23 and is displayed. Therefore, when the switch _S1 is operated, Then, the current month information and the calendar table for the current month are displayed on the display device 5.

Further, _S2 is a +1 month switch, which is used to advance the calendar, and the signal outputted via the one shot circuit 17 is sent to the OR circuit 16.
The output signal of the OR circuit 16 is further connected to the specific day of the week column information correction means 18 to which the information of the display month storage means 15 is given.
9, it is applied to the display month storage means 15 as a +1 signal. Also, S ₃ is −
This is a January switch and is used to return the calendar to the previous month.One shot circuit 2
0, and the output signal of the one shot circuit 20 is given to the display month storage means 15 as a signal for -January, and after passing through the delay circuit 21, it is also given to the specific day of the week column information correction means 18. It is set as.

The specific day of the week column information correction means 18 is provided in order to always make the numerical value information stored in the specific day of the week column storage means 11, that is, the Sunday column information, correspond to the display month information stored in the display month storage means 15. As shown in FIG. 3, the signal line from the OR circuit 16, the signal line from the delay circuit 21 when the January switch _S3 is operated, and the display month storage means 15
An AND circuit decoder is constituted by a signal line corresponding to a large month from , a signal line corresponding to a small month except February, and a signal line corresponding to February of a leap year.For example, an OR circuit 16 For the +1 month control, if the content of the display month storage means 15 is a large month when a signal is given from If it is a large month, a +4 signal is output, a small month is a +5 signal, and if it is February of a leap year, a +6 signal is output, and for -1 month control, a large month signal is output. +3 is output for a small month, +2 is output for a month with a small month, and +1 is output for a February month of a leap year and given to the specific day of the week column storage means 11 for addition.

Note that in February of a normal year, no addition signal is output.

Therefore, when the display month automatic update control means 13, which is given the month information of the display month storage means 15 and the month information from the month counting circuit 3d, receives the drive signal from the month-end adjustment circuit 12, it updates these months. Determine whether the information matches. When a match is detected in the display month automatic update control means 13, a match signal is given to the specific day of the week column information correction means 18 via an OR circuit 16, and a flip-flop 7 is set. A signal from the AND circuit ₉ accompanying the pressing operation of the switch S1 is applied to the display month storage means 15 and the specific day of the week column storage means 11, respectively, so as to reset the contents written therein.

In such a configuration, in order to display the contents of the current month, that is, the month being counted by the counting circuit 3, on the display device 5, the switch _S1 is operated. When switch _S1 is operated, one pulse signal is output from one-shot circuit 6, and flip-flop 7
The output of is switched from to Q, and a signal is output from output Q. At this time, one signal is output from the AND circuit 8, a drive signal is given to the specific day of the week column detection means 10, and the AND circuit 14
will be released. The specific day of the week column detecting means 10 sends the column of a specific day of the week in the calendar, in this embodiment, the column of Sunday, to the detected specific day of the week column storage means 11 based on the information from the day of the week counting circuit 3b and the day counting circuit 3c. For example, "Monday the 28th"
In this case, as is clear from FIG. 2, the output of the specific day of the week sequence detection means 10 becomes "5", and this content is written into the specific day of the week sequence storage means 11. Also, the AND circuit 14 is opened, and the month information (for example, August) of the month counting circuit 3d is written into the display month storage means 15. Then, by the Q output of the flip-flop 7, the numerical value part 5b for the date is displayed, AND circuits 22 and 23 are opened, and the contents of the specific day of the week column storage means 11 are transferred to the specific day of the week display part 5a, and the display month memory The contents of the means 15 are transferred to the month display section 5c. Therefore, the specific day of the week display section 5a
The "SU" face above the 6th column is displayed, specifying the display position for Sunday, and the month display section 5.
August is displayed in c, and 8 as shown in Figure 4A.
A monthly calendar is displayed.

Next, a case in which the contents of the month counting circuit 3d change from, for example, August to September in this display state will be described. First, before the month and day are changed by the month-end adjustment circuit 12, a drive signal is given from the month-end adjustment circuit 12 to the display month automatic update control means 13, thereby causing the contents of the display month storage means 15 (8
A match between the month) and the contents of the month counting circuit 3d (August) is detected. This coincidence signal is sent to the specific day of the week column information correction means 18, which then outputs a predetermined addition signal.In the above example, since the content of the display month storage means 15 is August, a +4 signal corresponding to this is output. is added to the storage contents of the specific day of the week column storage means 11, and the specific day of the week display section 5a is displayed based on the contents of the specific day of the week column storage means 11. Further, the coincidence signal is delayed by the delay circuit 19 and is given to the display month storage means 15, and its content (August) is increased by +1 to make it September, which is displayed on the month display section 5c. Therefore, as shown in FIG.
Can be changed to the moon.

Next, operate +1 month switch S ₂ , for example 11
The case where a monthly calendar is displayed will be explained. When the switch _S2 is operated once, the specific day of the week column information correction means 18 first displays the display month storage means 1.
Based on the contents of ``5'' (September), an addition signal of ``5'' is sent to the specific day of the week column storage means 11 and added. Then, the +1 month signal is delayed by the delay circuit 19 and the content (September) of the display month storage means 15 is changed to +1 month.
1 and then change it to October. Therefore, when the switch _S2 is operated again, the same operation as described above is performed, and the specific day of the week column storage means 11 and the display month storage means 1 are
5, contents corresponding to November are written, and the calendar for November is displayed on the calendar display device 5.
In this state where the month (November) that is earlier than the current month (September) is displayed on the display device 5,
A case where the monthly counting circuit 3d is changed monthly and rewritten to the contents of October will be explained. When the display month automatic update control means 13 is driven at the time of month change, the contents of the month counting circuit 3d are September, while the contents of the display month storage means 15 are November. Therefore, when the month counting circuit 3d changes the month, the display month automatic update control means 13 does not output a coincidence signal, so the contents of the specific day of the week column storage means 11 and the display month storage means 15 are retained as they are, and the display device 5, the November calendar resulting from the previous operation will continue to be displayed.

When the -January switch _S3 is operated, the contents of the display month storage means 15 (September) are first subtracted by 1, and then, based on this value (August), a +3 signal is sent from the specific day of the week column information correction means 18. As a result, the calendar for August is displayed on the calendar display device 5. Then, the current month (9) is displayed on the calendar display device 5.
Even if the contents of the month counting circuit 3d change while the month (August) earlier than the previous month (August) is displayed, the coincidence signal will not be output, as in the case of +1 month switch _S2 operation described above. The calendar display is not affected in any way, and the August calendar is retained and displayed.

Therefore, the monthly information counted by the counting circuit 3,
In other words, if you display the calendar for the current month, the month on the calendar that is displayed will automatically change even if the month changes, and if you select and display the calendar for the desired month, for example, Even if the contents of the month are incremented by one month in several circuits, if the selected and displayed calendar changes to the next month, it will not be missed, making it very easy to use when making plans, schedules, etc.

In the embodiment described above, only the calendar display is displayed, but instead of this, a configuration may be adopted in which the time, day of the week, and day clock information are displayed together with the calendar display. Further, in the above embodiment, +1 month and -1 month switches were used as external operation switches for changing the displayed month, but when the calendar is incorporated into a small electronic calculator, the calendar of the desired month can be changed using the numeric keypad. may be displayed. Further, in the above embodiment, a calendar in which date numbers are arranged in seven columns is used, but it may be arranged in 14 columns, or in which date numbers are arranged in one horizontal column. That is, various changes may be made within the scope of the present invention.

As described above, the calendar display device of the present invention arranges date numerical values from "1" to "31" in a plurality of columns according to the seven-day calendar table, and also arranges date numerical values from among the plurality of date numerical columns. Calendar display units 5a and 5b are provided with date numerical string clarifying means for independently indicating each of the plurality of date numerical strings in order to clearly indicate which column corresponds to a particular day of the week; , a month display section 5c for displaying which month the calendar is displayed on the calendar display section, and a counting means 3 for counting the reference signal to obtain information on the current month, day, and day of the week; Display month storage means 15 stores the month information obtained by the counting means and supplies the stored information to the month display section; A specific day of the week column detection means 10 detects which date numerical column of the calendar display section corresponds to a specific day of the week in a month, and stores information detected by the specific day of the week column detection means and stores the stored information. The month has a specific day of the week column storage means 11 which is supplied to the date numeric string specifying means and an operation switch, and when the switch is operated, a pulse is generated to change the month information stored in the display month storage means. Modified pulse generation means
S ₂ , 17; S ₃ , 20 are connected to the month change pulse generation means, the display month storage means and the specific day of the week storage means, and when the month change pulse is supplied from the month change pulse generation means, Specific day of the week column information correction means for correcting specific day of the week column information stored in the specific day of the week column storage means to specific day of the week column information corresponding to the changed month information of the display month storage means that is changed by the month change pulse. 18, when the month information of the counting means is updated, the month information before the update is compared with the month information of the display month storage means, and the coincidence detection signal is used as the month change pulse of +1 month. The display month storage means and the display month automatic update control means 13 for supplying the data to the specific day of the week column information correction means are provided, and if the calendar displayed on the calendar display section is the current calendar, the count counting means When updating monthly information, the calendar displayed on the calendar display section is automatically updated to the next month's calendar, and if the calendar displayed on the calendar display section is for a month different from the current month, the calendar Even if the monthly information is updated by several means, the calendar for the different month is continuously displayed, so in normal use when the calendar for the current month is displayed, the user has to update the displayed month when the month changes. It is not necessary to do this, and it is of course possible to display the calendar for any month. For example, if it is near the end of the month and there is no need to check the calendar for the current month, the next month will be displayed from that point on. It is an extremely convenient and highly practical calendar display device that can continue to display the next month's calendar until it is finished.
