Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for setting the month and date on both sides of a display, and particularly relates to a method for setting the month and date on both sides of a display.
isplay) and L CD (1iquid crys
The present invention relates to a method for setting the month and date on the display screens of various devices such as display devices such as L displays, recorders with timer functions, and other devices in which it is necessary to set the month and date.

[Technical Background of the Invention] Display devices such as CRTs and LCDs, recorders with timer functions, etc. have the display screen set in advance with the date and time of the measurement, etc., and this can be recorded for future reference. There are many things that need to be kept as records.

FIG. 1 shows a schematic configuration of an example of a device having such a date setting function. There is. Of these, the display screen 31 of the display section 30 is provided with a month/day display field 32 consisting of a month display section 33 and a day display section 34 as shown in FIG.
The location of the cursor 35 can be notified by appropriate means, such as by positioning the cursor 35 and making that location blink. Further, as shown in FIG. 3, the operation unit 20 is provided with a numerical value change key 22 and a downward change key 23, so that a desired value among a series of numerical values can be reached more quickly. key 21 and +
A cursor movement key 25 consisting of a left movement key 26 and a right movement key 27 is provided so that the cursor 35 can be moved in the left-right direction.

Next, in relation to the above device, the display screen 31 of the display unit 30
The conventional method for setting the month and date will be explained. 7th
The figure shows the situation when the month display section 33 is changed to the month "2", taking as an example a case where "3" month "31" day is already set on the display screen 31. That is, press the cursor movement key 25 to move the cursor 3 as shown in FIG.
5 on the month display section 33 and press the upward change key 22 of the numerical value change keys 21 once to change the numerical value on the month display section 33 from "3" to "2" as shown in FIG. 7 (b). .

In this case, the maximum number of units corresponding to each month is stored in the memory in advance, and the maximum number of days in the month is displayed between the maximum number of days in the month and the date automatically converted and displayed. (i.e. 30 shares or 3
If the month is smaller than 1 day), the number of units displayed is set to be replaced by the maximum number of units of the month, so if you change the number in the month display section 33 from ``3'' to ``2''. At the same time, the day display section 34 could also be automatically changed to "29", which is the maximum number of days in February (the number of days in a leap year).

[Problem to be Solved by the Invention 1] Next, let's take as an example a case where the month and day display field 32 displays "3" month "20" day, and change it to "1" month "31" day. 8, how the month/day display column 32 changes when this is done using the conventional method will be explained. First, as shown in FIG. 8(A), position the cursor 35 at "20" in the day display section 34 in the month/day display field 32, press the upward change key 22 of the numerical value change keys 2I the required number of times, Set it to "31" as shown in (b). Then,
Press the left side movement key 26 of the cursor movement keys 25 to move the cursor 35 to the month display section 3 as shown in FIG.
3, and press the downward change key 2 in the numerical value change key 21.
Press 3 once to change "3" to "2" as shown in Figure 8 (d).
”. At this time, for the reason already mentioned, the date display section 34 is also automatically changed from "31" to "29", and even if the downward change key 23 is pressed again, that state remains unchanged. Even if "2" is changed to "1" as shown in FIG.
' will still be displayed as is.

In this way, even if the month display section 33 is changed from "2" to "1", "29" on the day display section 34 remains unchanged, so when using the conventional method, the left side of the cursor movement key 25 It is necessary to press the movement key 26, move the cursor 25 to the month display section 33, press the upward change key 22 in the numerical value change key 21 twice, and change the setting to "31", which only makes the setting work more complicated. However, if you accidentally overlooked this, you could end up setting the date incorrectly.

This invention was made in view of the problems of the conventional method, and its purpose is to always automatically display the maximum number of units corresponding to the changed month each time the month setting is changed. The purpose of the present invention is to provide a method for setting the month and date on a display screen.

[Means for Solving the Problems] The present invention has been made to achieve the above object, and includes a memory means for storing the maximum number of days in correspondence with a setting column, and a memory means for storing the maximum number of days in a changed month after the change. and a comparison means for comparing the magnitude with the set date, and when the set date is determined to be smaller by this comparison means, the display part of the month before change is replaced with this set date, and this set date is date switching means for switching to the maximum number of days in the month after the change, and when the comparison means determines that the set dates are greater or the same, and the month changes are consecutive, the date of the previous month It is provided with a return means that compares the size of the display section and the 30th day, and if it is larger or the same, returns the display section of the previous month on the set date, and when changing the display section, it corresponds to this change column. The feature of the configuration is that if the display section displayed does not exceed the maximum number of days in the month of change, it remains as is, and if it exceeds the maximum number of days in the month of change, it displays the maximum number of days in the month of change.

[Example] Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

As already mentioned, FIG. 1 shows the schematic configuration of an example of a device having a month and date setting function used for implementing the present invention, and includes the device main body 10, the operation section 20, and the display section 3.
It is entirely composed of 0 and 0. Of these, display section 3
The display screen 31 of 0 is provided with a month/day display section 32 consisting of a month display section 33 and a day display section 34 shown in FIG. The cursor 35 is configured so that it can be distinguished from others, so that the position of the cursor 35 can be known. Further, as shown in FIG. 3, the operation unit 20 is configured with an upward change key 22 and a downward change key 23 so that a desired value among a series of linked values can be reached more quickly. A numeric value change key 21, and a cursor movement key 25 consisting of a left movement key 26 and a right movement key 27 that can move the cursor 35 in the left and right directions are provided.

Note that instead of the NIF cursor 35, keys that can separately change the month displayed on the month display section 33 and the day displayed on the day display section 34 may be separately provided on the operation section 20. . Furthermore, a rotary encoder may be used instead of the numerical value change key 21 on the operation unit 20. Furthermore, the day displayed on the day display section 34 may be divided into the IO digit and the 1's digit so that they can be set separately.

FIG. 4 is a flowchart showing the processing procedure for setting month and day when the method of the present invention is applied to the apparatus having the above configuration.

That is, at the start of the operation, reading processing is performed manually using the keys from the operation unit 20.

Next, it is determined whether the key input is for changing the month, the day, or some other process, and if the key input is for changing the month, , First, by inputting a specific numerical value into the variable name month, the month setting is changed. Specifically, by operating the cursor movement key 25 on the operation unit 20 shown in FIG. 35 and then set the desired month using the numerical value change key 2I.

After setting the value of month in this manner, a predetermined date restriction process is performed according to a date restriction routine to be described later.

On the other hand, if the key human power is for day change,
By inputting a specific value into the variable name day, the setting for the 5th day can be changed. Specifically, by operating the cursor movement key 25 shown in FIG.
Day display section 34 of month and day display section 32 displayed on
This can be done by moving the cursor 35 to and setting the desired date using the numerical change key 21 on the operation unit 20.

In this way, after setting the month value and processing according to the predetermined date restriction routine, or after setting the day value, the set month value or day value is set. The basis weight is changed to the based weight, and the month and day are displayed in the month 11 display field 32 on the display screen 31 of the display unit 30, and the operation ends.

Regarding the specific display mode of the month and day displayed in the month and day display field 32 in this case, in addition to the illustrated example, for example,
3 is displayed in alphabets such as "MΔY", and the date display section 34 is displayed in numerical values such as "20", etc.
An appropriate aspect can be arbitrarily selected as required.

Note that when using the keys manually, it is of course possible to perform other predetermined processing by operating other keys (not shown) on the operation unit 20.

FIG. 5 is a flowchart showing a specific processing procedure of the "date restriction routine" step in the flowchart of FIG. 4 when the key input is to change the month.

In other words, the process for date restriction begins with DAY-MAX, which is the variable name indicating the maximum number of days in the month.
For each month from January to December, the maximum number of days in the corresponding month (variable name month) is input into the memory means and stored (February is 29 [1] in a leap year).

Then, to determine whether there is a change in date restrictions,
Whether DAY-MAX≧day exists between DAY-MAX and the variable name day that indicates the set day, or DAY-MAX
The comparison means determines whether X<day.

Below, there are changes in date restrictions. DAY-MAX < day
and DAY-MAX≧ with no change in date limit.
We will explain each term separately depending on the case where it is a day.

First, DAY-MAX< day, that is, day
When the 30th is 310, the maximum number of days in the month is smaller than the set value, so the date limit needs to be changed, and the variable name that indicates the display part of the previous month is changed.
-11U Input the day set in F and save the basis weight. Next, after inputting DAT-MAX, which is the maximum number of units for the month, into the day and performing processing by the unit weight switching means to limit and change the EJ attachment to the maximum number of units, the process returns to the predetermined step in Fig. 4. ,
Display the month and date on the display screen and end the setting process. Therefore, DAY-MA is the maximum number of units for the month.
After performing the manual processing of .

On the other hand, 1) DAY-MAX≧d by means of comparison in Section 71
If it is determined to be ay, it is a case where the set [J is the same as or smaller than the maximum number of units for that month, so there is no need to change the limit with [], and the month change is continuous. The next step is to determine whether or not it is. In this determination step, it is determined whether or not the month is being changed continuously without moving the cursor 35 while keeping it positioned on the month display section 33, and after the date restriction change processing is performed, Determine whether any operation other than changing the month has been performed. If it is determined that the month is changing continuously without any operation other than changing the month, the magnitude relationship is compared between the variable name DAY-BOF and the 30th, and the value is set. The process moves on to a step in which it is determined whether or not DAY-BUF, where the word ``day'' is the previous month's display [], is to be saved. In this case, D.A.
Y-B IJ F230 days, that is, DAT-B
When it is determined that the UF is the saved value 30[ ] or 310, the DAY-BUF that was saved is input into the day via the recovery means in order to restore the date. In this way, after inputting DAY-BUF to day, clear the DAY-BUF and erase its contents so that this DAY, -BUF will not be processed again. Returning to the predetermined step in FIG. Further, when it is determined that DAY-BUF <30 days, the DAT-[IUF is immediately cleared to erase its contents, and the process returns to the predetermined step in FIG.

In addition, in the flowchart of FIG. 5, DAY,...
You may also give other variable names instead of BUF to make the determination.
Furthermore, other variable names can also be used.

Also, if it is determined that the month has been changed for the first time in the step of determining whether or not the months have been changed consecutively, the DAY-BIIF is immediately cleared in the same way, and the predetermined step in Figure 4 is performed. to return to.

FIG. 6 shows a case where the month/day display column 32 is set to "3" month "31" day and the setting is changed to "rlJ month "31J day" according to the above processing procedure according to the present invention. It shows a series of fluctuations on the display screen 31 when the month and day are set.

That is, as shown in FIG. 6(a), the month and day display column 32 of the display screen 31 in the display section 30 is
is displayed as "3", the day display section 34 displays "31", and the cursor 35 is located on the month display section 33 and is blinking. The month display section 33 in the month/day display field 32 in such a state can be changed as shown in FIG. 6 (b) by pressing the direction change key 23 of the numerical value change key 21 shown in FIG. It is possible to change from "3" to "2". In this case, the date display section 34 is also automatically changed to "29", which is the maximum number of days in the month, by the memory means. Next, by pressing the downward change key 23 of the numerical value change keys 21 shown in FIG.
1". In this case, the month display section 34 can also be automatically changed to "31" which is the maximum number of units for the month at the same time through the comparison means, date switching means and return means, as shown in FIG. 8 in the conventional method. It is possible to avoid displaying the date as shown in (e).

[Effects of the Invention] As described above, according to the present invention, the month and day corresponding to the maximum number of units of the month are automatically displayed in the month and day display column on the display screen of the display unit. This makes it possible to eliminate errors in date setting, and to simplify the date setting work itself.
