In addition, if you press another function key to start the schedule function, you can sequentially register schedules on any date by inputting number keys or letter keys.
It is also possible to rearrange the schedules registered in this way in order of date, and display them on the display device.

Furthermore, conventional electronic devices such as this can calculate the number of days until the scheduled departure date based on the calendar of the timekeeping function by inputting the current date and a date such as the scheduled departure date for an overseas business trip. Some had a function to calculate the number of days.

[Problems 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. It has at least a timekeeping function that measures the current date based on a calendar, and a schedule function that registers an input schedule with a specified date and displays this schedule on a display section in response to a call. In the electronic device, when any schedule is displayed by the schedule function and a predetermined input is received from the input section, the date of the displayed schedule and the current date from the time measurement means are taken into the processing section. a date importing means; a days calculation means for calculating the number of days from the current date to the schedule date based on the calendar of the timekeeping function when the date importing means imports two dates into the processing unit; The device is characterized by comprising a number of days display means for displaying the calculation result on a display unit when the number of days is calculated.

[For production]

The time measurement function measures the current date in real time based on the calendar based on the date obtained through initial settings. This timekeeping function has a calendar consisting of data such as major months, minor months, leap years, etc., or a calendar consisting of a means to calculate these based on the Greorian calendar, etc., and can be used to measure not only the present but also past or future dates. You can also get The schedule function is registered by the user inputting the date and schedule contents from the input section. Then, when the user operates a call key or the like on the input section, the specified schedule is displayed on the display section. Furthermore, this schedule may be displayed as a monitor during registration using the schedule function.

When a predetermined input is received from the input unit when any schedule is displayed by this schedule function, the date importing unit processes the date of the displayed schedule and the current date from the timekeeping unit. Incorporate into. 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 schedule.

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 schedule date based on the calendar of the timekeeping function. The number of days can be calculated by simple subtraction if the two dates are in the same year and month. However, if you cross the moon,
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. Furthermore, if the schedule displayed by the schedule function is from 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 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 often needs to calculate the number of days when registering or confirming a schedule using the schedule function. The first day of this calculation of days is usually the current date. Therefore, when the schedule is displayed, if the present invention were to be able to calculate the number of days from that day to the day on which the schedule is registered, it would be possible to calculate the number of days with a simple operation in most cases where it is necessary to calculate the number of days. You will know the number of days.

). For example, if the current day is January 1, 1989, the display will be as shown in FIG. 5(a).

When the schedule for the day is displayed, press the number of days calculation key 30.
It is determined whether or not has been pressed (S3), and if the number of days calculation key 3c has not been pressed, it is subsequently determined whether or not the call key 3e has been pressed (S4). Since there is no point in calculating the number of days when the schedule for the current day is displayed, the call key 3e is initially pressed before the number of days calculation key 3c. Therefore, when the call key 3e is first pressed, the schedule for the previous day or the next day is searched according to the specified direction, and the display on the display section 2 is rewritten to the newly searched schedule (S5).
Then, when the schedule for the previous day or the next day is displayed,
Since the process returns to S3 again, the desired schedule can be displayed by repeating the processes from 83 to S5. For example, if the target schedule is an overseas business trip on February 10 of the same year, by repeatedly pressing the next day direction of the call key 3e, a display as shown in FIG. 5(1) can be obtained.

Note that if the call key 3e is not pressed in S4, other input keys 3 to 3 used in the schedule mode are pressed.

If 8 has not 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. Furthermore, if any of the input 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 target schedule displayed, first the date of the displayed schedule and the current date obtained from the RTC 16 are set to a predetermined address on the RAM 15 (S6), and then , the number of days is calculated based on these dates (S7). 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 two dates based on a programmatically configured calendar.

When the calculation of the number of days is completed in S7, the display unit 2 is rewritten to display the calculation result (S8).

In the above example of January 1st and February 10th, the calculation result is 40 days, so the display section 2 shows the following as shown in Fig. 5(c).
This number of days is displayed together with the message, and once this number of days has been displayed, the process returns to S3 and waits for a key input.

As a result of the above processing, when the user confirms the schedule for an overseas business trip, the user can easily know the number of days from the current day to the departure date by simply performing the simple operation of pressing the number of days calculation key 3c.

In the above example of calculating the number of days, if the call key 3e is pressed in the direction of the previous day in S4, for example, the 511iN(d
), the schedule for December 10th of the previous year is displayed. When the number of days calculation key 3C is pressed in this state, the number of days is calculated by the processes of 86 and S7 in the same manner as in the above example. However, in this case, the calculation result will be a negative value, so the display on the display section 2 will be
As shown in Figure (e), the number of days is given a minus sign. Therefore, the user can know the number of days that have passed since the date of the previously displayed schedule.
