Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a number-of-days calculation device in an electronic device having a calendar function or the like.

[Conventional technology]

2. Description of the Related Art In recent years, notebook-type or card-type electronic devices comprising microcomputer systems that perform various information processing based on timekeeping functions, calendar functions, etc. have become widely popular among businessmen and the like.

Such electronic devices are equipped with character keys, numeric keys, cursor keys, and various function keys as input sections on a notebook-type spread or card-type board, and an LCD (LCD) as an output section.
A display device such as a liquid crystal display is provided. Also, the inside has a CPU (central processing unit), storage device, RTC (real-time clock), etc. as a processing section, and according to the input from the input section based on the program in the storage device, the CPU
U performs various processing.

Therefore, when the user presses a predetermined function key, the current date and time can be displayed using the timekeeping function, or a calendar for any month can be displayed using the calendar function.

Furthermore, conventional electronic devices such as this have the ability to calculate the number of days until the scheduled date based on the calendar used by the clock function or calendar function, for example, by inputting the date of a certain scheduled date and the current date. Some had a function to calculate the number of days.

[Problem to be solved by the invention]

However, such a number-of-days calculation function requires inputting the year, month, and day of two dates using numerical keys or the like, which is cumbersome to operate.

Therefore, although conventional electronic devices such as notebook-type devices have a function to calculate the number of days, they have a problem in that they cannot be fully utilized because they are cumbersome to operate.

[Means to solve the problem]

In order to solve the above-mentioned problem, an electronic device days calculation device according to the present invention includes an input section for inputting operation details, a processing section for performing predetermined processing according to the input, and a display section for displaying the processing results. , and is equipped with at least a timekeeping function that measures the current date based on a calendar, and a calendar function that displays a calendar within a specified range based on the calendar on the display. There is a date specification means for specifying any date on the displayed calendar, and when a certain range of calendars is displayed and any date is specified, if a predetermined input is made from the input section, the date is displayed. a date importing means that imports a specified date on a calendar and the current date from the timekeeping means into a processing unit; The present invention is characterized by comprising a number of days calculation means for calculating the number of days from the date to a designated date, and a number of days display means for displaying the calculation result on a display unit when the calculation means calculates the number of days.

[For production]

The time measurement function uses the date obtained through initial settings as a base point and measures the current date in real time based on the calendar. Therefore, by importing the time measurement results of this time measurement function into the processing unit, information such as the current date and time can be obtained.
This can also be displayed on the display unit. A calendar consists of data such as major months, minor months, leap years, etc., or means for calculating these based on the Greorian calendar.

The calendar function is for displaying, for example, a calendar listing dates and days of the week on the display unit based on this calendar. At this time, the user can specify any month in the past, present, or future within the limits that the calendar can accommodate. Note that the range of the displayed calendar is not limited to monthly units, and the display format of the calendar can also be set arbitrarily.

The date designation means designates an arbitrary date on the calendar displayed by the calendar function, and the user designates the date by, for example, moving a cursor over one of the displayed dates. At this time, for example, when the calendar function is first executed, it automatically specifies the range that includes the current date and displays that calendar, and also specifies the current date on the calendar, and also displays the range that includes the current date. When a calendar in the specified range is initially displayed, the first date in the range is automatically specified, and the default state is set for each, thereby eliminating the need for explicit instructions or specifications by the user. You can also.

When a range of calendars is displayed by the calendar function and any date is specified, when a specified input is received from the input section, the date import method is used to import the specified date on the displayed calendar. The received date and the current date from the clock means are taken into the processing section. The predetermined input may be performed by, for example, providing a function key on the input unit for performing a series of processes of the present invention and having the user press the function key. Furthermore, a predetermined input may be made by pressing one or more keys for other purposes that are not used when displaying the calendar.

In addition, in the conventional number of days calculation device, each of the above two dates had to be inputted using the numeric keys or the like on the input section.

When this date importing means imports two dates into the processing section,
The number of days calculation means calculates the number of days from the current date to the designated date based on the calendar. The number of days can be calculated by simple subtraction if the two dates are in the same year and month. However, when crossing months, it is necessary to obtain information from the calendar as to whether the months in between are large or small.

Furthermore, if the last day of February is used, information on whether the year is a leap year is also required.

When the calculation means calculates the number of days, the number of days display means displays the calculation result on the display section. At this time, if a message indicating the two dates and the number of days between them is displayed together with the number indicating the number of days, it will be easier for the user to understand. Further, if the date specified by the date specifying means is in the past, the number of days that have passed up to the present can be indicated by adding a minus sign to the number of days to be displayed.

Note that the number of days calculation means and the number of days display means may be the same as those used in conventional number of days calculation devices.

Here, the user generally determines or confirms the schedule while looking at a calendar that can list dates and days of the week for -months, for example, and it is often necessary to calculate the number of days at this time. The first day of this calculation of days is usually the current date. Therefore, if the present invention makes it possible to calculate the number of days from point 1 to the specified date on the calendar when the calendar is displayed, in most cases where it is necessary to calculate the number of days, it will be possible to use the hour wheel operation. Now you can know the number of days.

The electronic device with the above configuration can perform various functions by having the CPU II perform predetermined processing in accordance with the input from the input keys 3 to 8 based on the operation program in the ROMI 4, and displaying the processing results on the display unit 2. Execute.

The specific operation of the number of days calculation function in this electronic device will be explained based on the flowchart of FIG. 1 and the display example of FIG. 5.

When you press the calendar key 3a to enter the calendar mode, first in step (hereinafter referred to as "S") l, the RTC1
The current date is read from 6, and then, based on the calendar configured as a program, the calendar of the month that includes that date is displayed on the display unit 2 (S2). Also, at this time, the cursor 2a on the display section 2 is placed on the number indicating the current date. Therefore, for example, if the current day is January 1, 1989, the display will be as shown in FIG. 5(a).

When this calendar is displayed, it is determined whether the number of days calculation key 3C has been pressed (S3). If the number of days calculation key 3C is not pressed, it is determined whether the call key 3e is pressed (S4). Further, if the call key 3e is not pressed either, it is determined whether the cursor key 6 has been pressed (S5).

Here, you first need to specify the desired date, so
The call key 3e or the cursor key 6 will be pressed. When the call key 30 is pressed, the display on the display section 2 is rewritten to last month's or this month's calendar depending on the direction indicated by the key (S6). At this time, the cursor 2a on the display section 2 is placed on the number indicating the first day of the new month. Then, when a new calendar is displayed, it returns to S3 again, so
By repeating the processes of S3, S4 and S6,
By specifying the year and month of the desired date, you can display the calendar for that month.

When the calendar for a certain month is displayed in this way, the next step is to press the cursor key 6 to move the cursor 2a and specify the day of the desired date. The upper cursor 2a moves (S7
). At this time, the cursor 2a is moved to the pressed cursor key 6.
When the right key 6d is pressed, the button moves to the next day's date, and when the down key 6b is pressed, the button moves to the date of the same day of the week next week. Further, the left key 6c returns to the previous day's date, and the up key 6a moves to the date of the same day of the week last week. Then, when the cursor 2a moves in any direction, the process returns to S3, so by repeating the processes of S3, S4, S5, and S7, the cursor 2a can be moved to the desired date and the date specified. Can be done. For example, in the above example, if the target date is February 10th of the same year, press the next month direction of the call key 3e once to display the February calendar, and press the down key 6b of the cursor key 6 once to the right. By pressing the key 6d twice (or continuing to press it while the cursor 2a moves for two days), a display as shown in FIG. 5(b) can be obtained.

If the target date is this month, the user directly presses the cursor key 6 to move the cursor 2a to that date without pressing the call key 3e first. If the desired date is the 1st of a month, press the call key 3e to display the calendar for that month, and the cursor 2a will already be at 1.
Since it is located above the sun, there is no need to press cursor key 6 again.

Note that if cursor key 6 is not pressed in S5, other input keys 3 to 8 used in calendar mode are pressed.
Detection is performed. And here, either person oyster-3~B
If none of the input keys have been pressed, the process returns to S3 and the above process is repeated until any of the input keys 3 to 8 is pressed again. Further, if any of the keys 3 to 8 is pressed, the process corresponding to that key will be executed.

When the number of days calculation key 3C is pressed in S3 with the cursor 2a moved to the target date, first the date consisting of the year and month of the displayed calendar, the day on which the cursor 2a is located, and the date obtained from the RTC 16 are calculated. Save the current date to RAM1
Then, the number of days is calculated based on these dates (S9). The calculation of the number of days here is performed by calling a program routine for calculating the number of days stored in the ROM 14. This routine then calculates the number of days between the two dates based on a programmatically configured calendar.

When the calculation of the number of days is completed, the display unit 2 is rewritten to display the calculation result (SIO). In the above example of January 1st and February 10th, the calculation result is 40 days, so the display section 2 shows
As shown in FIG. 5(C), this number of days is displayed together with the message. And when this number of days is displayed,
The process returns to S3 and waits for key personnel.

As a result of the above processing, when the user recognizes the desired date on the calendar, he or she can move the cursor 2a over the date and press the number of days calculation key 3C, and the user can start the desired date from that day. You can easily find out the number of days until the next day.

In addition, from the state shown in FIG. 5(a) in the above example of calculating the number of days, for example, if you display last month's calendar using the call key 3e and specify the 10th day using the cursor key 6, a display as shown in FIG. 5(d) is displayed. becomes. Then, when the number of days calculation key 3C is pressed here, 88 and S
The number of days is calculated by the process in step 9. However, in this case, since the calculation result is a negative value, the display on the display section 2 in the SIO will be the number of days with a negative sign, as shown in FIG. 5(e). Therefore, the user can know the number of days that have passed since the target date.

〔Effect of the invention〕

As described above, the electronic device days calculation device according to the present invention includes an input section for inputting operation details, a processing section for performing predetermined processing according to the input, and a display section for displaying the processing results. However, in an electronic device that is equipped with at least a timekeeping function that measures the current date based on a calendar, and a calendar function that displays a calendar within a specified range based on the calendar, A date specifying means for specifying an arbitrary date on a calendar, and when a certain range of calendars are displayed and any date is specified, when a predetermined input is made from the input section, the date is displayed. A date importing means imports a specified date on the calendar and the current date from the timekeeping means into the processing unit, and when the date importing means imports the two dates into the processing unit, the current date is determined based on the calendar. It is characterized by comprising a number of days calculation means for calculating the number of days from to a specified date, and a number of days display means for displaying the calculation result on a display unit when the calculation means calculates the number of days.
