It was equipped with a function to output a calendar. An example of the display output is shown in FIG.

FIG. 1(A) shows a display example of a digital watch having a function of displaying and outputting a calendar. By setting a desired year and the first day of the month, a calendar for one month is output. In addition, Fig. 1 (B) shows an example of 198 in an electronic desktop calculation m (hereinafter referred to as a calculator) that has only one line of display.
A display example is shown when March 23, 4th year is input.

Calculators, digital clocks, personal computers, etc. that have these clock functions simultaneously set the date and
As shown in Figure (C), the hour φ minute or hour φ minute e second is set, and the date is updated automatically based on the set time. If you think about it, today is ``3323rd, 984'' and ``March 3rd''.
If you want to know what day of the week "0th day" is, enter "rl March 30, 984" in date set mode, and the calendar will be displayed for the first time.
0 day" will be displayed, and you can check the day of the week here. After confirming this, I had to set it back to today's date, March 23, 1984.

Also, on electronic devices and personal computers called schedulers, if you input March 1984, March (1 month) will be displayed, but if you want to see the next month's calendar, etc. Set mode to 198
By inputting April 4, the calendar for April will be displayed.

Also, if you want to schedule on April 1st using a scheduler, etc., you have to enter April 1st and then schedule the time etc. You also have to change the mode and set it as the date. However, the disadvantage was that the operation was very complicated.

[Objective] The present invention has been made in view of the above-mentioned drawbacks of the prior art, and an object of the present invention is to provide an electronic device that can change the calendar display on a daily basis with a simple operation.

Another object of the present invention is to arrange a transparent keyboard overlapping the calendar display section, and by inputting specific keys on the transparent keyboard, the date can be changed in the same way as a daily calendar.

Another objective is to provide electronic equipment that can be restored to its original state.

[Example] Hereinafter, an example of the present invention will be described with reference to the attached drawings.

FIG. 2 is a perspective view showing the appearance of an electronic device using a display device with a transparent keyboard according to an embodiment of the present invention. In the figure, 10 is a display device with a transparent keyboard CDPK)

Further, 31 to 35 are key input units consisting of ordinary key switches other than the transparent keyboard, 31 is an rMODEJ key for converting various processing modes such as schedule, calendar, and calculator processing modes, and 32 is an input data key. The ``rEDIT'' key 33, which is used when executing nibite processing such as modification, correction, and change, validates the key input data group.

The rSETJ key 34 is used to input that processing is possible, and the rENTERJ key is used to set input data in the RAM 24, which will be described later.

Further, 35 is a power key of this embodiment.

FIG. 3 shows a block diagram of an electronic device having the DPKIO shown in FIG. 2.

In FIG. 3, numeral 10 is the liquid crystal display (DPK) shown in FIG.
It is composed of an LCD display device 10a and a transparent keyboard lOb. Reference numeral 20 denotes a central processing unit (CPU) that controls general control of this embodiment, and the CPU 20 stores an arithmetic control section 21, a keyboard interface 22, an operation program for the arithmetic control section 21 according to the flowchart of FIG. A read-only memory (ROM) 23 with 8 bits/l word random memory for temporarily storing input data, operands, operands, various calculation states, etc. Access memory (RA)
M) 24. In the RAM 24, there is a buffer BUF that temporarily stores the input key data.
F, a register TIME that stores the time, a purpose register DATE that stores the date data, and a flag, FM flag, and FS flag, and 30 is a transparent keyboard
This is a key input section consisting of keys 31 to 35 other than b.

A clock circuit 25 updates the register TIME at predetermined time intervals.

A partial cross-sectional view showing the structure of DPKIO is shown in FIG. 4. In FIG.
42b is a dot spacer that holds the electrodes 41a and 41b at a predetermined interval, 44 is an upper polarizing plate, 45 is an upper glass, 46 is a lower glass, 47 is a lower polarizing plate, and 48 is a reflecting plate. The upper polarizing plate 44 to the reflecting plate 48 form a known liquid crystal display device.

In this way, a transparent keyboard l is placed above the liquid crystal display device 10a.
By arranging the transparent keyboard 1Ob, arranging the key switches of this transparent keyboard 1Ob in an X-Y matrix key configuration, and inputting characters, numbers, and figures displayed on the display device 10a by pressing down, the arithmetic control unit 21 can control the keyboard interface 22.
It detects this input via the , recognizes it as an input from a key switch with the displayed function, and performs processing corresponding to the key input.

The operation of this embodiment, which consists of one or more of the following configurations, is performed by the CPU 20.
The processing procedure stored in the ROM 23 will be explained with reference to the flowchart of FIG. - Immediately after the power is turned on, everything in RAM24 is cleared.
The FM flag has also been reset. Therefore, the process advances from step 51 to step S3. In step S3, the FS flag is checked to see if the setting of the "year, month, and day" has been completed. Initially, the "year, month, and day" have not been set and the FS flag has been reset, so step S3
The process then proceeds to step S9.

Since nothing is set in step S9, some input means is required, such as outputting a typewriter keyboard onto a display device with a transparent keyboard.Next, in step S9, whether there is a key input from the DPK10 or not. If there is no key input, the process returns to step S9, and this loop continues until there is a key input, or an external "BREAK key" (not shown) is pressed.
You can get out of this state by inputting a key such as . Here, if there is a key input, the process advances from step S10 to step Sll, and in this step S11, it is determined whether the key input is a numeric key, and if it is not a numeric key, the process advances to step 516, but If it is a numeric key, it is determined in step 312 that it is the input of 1 year, month, and day, and the process proceeds to step 513. In step 313, press E.
It is checked whether the NTE R.'' key (data input key) has been pressed and input, and if it has not been input, step S9
The typewriter keyboard is displayed in an input-enabled state, and the primary numeric keys can be entered. However, in step 313, after inputting the input data (year, month 1st, etc.)
ENTER” key is pressed, step 514
The input data is stored in the buffer BUFF of the RAM 24 in the date register DATE, and the FSy lag indicating the existence of date storage data is set in step S15, and the process returns to step S1.

Further, if it is determined in step 511 that the key is not a numeric key, it is determined in step 316 whether or not the MODE key 31 has been pressed. Jump to another routine for processing.

If the MODE key 31 has been pressed in step 316, this is an instruction to change from the current processing mode to another one, so in step 517 the FM flag is set to "1" and the calculation Ia (calculator) mode is entered. and step 3
Proceed to Step 1, and this time from Step St to Step S
Proceed to step 2 to perform calculator mode, that is, normal calculator operation.

When the data set for "1 year, month, day" has been completed in step S3 and the FS flag is set ("1"), the process advances from step S3 to step S4a, and the CPU 20 refers to the date register DATE. LCD driver 3
A calendar is displayed on the display device 10a via a character generator (not shown) in 6. Also, the register TIME
The date register DATE is updated every 24 hours as shown in step S4b. An example of this display is shown in FIG. 6(A), and in the following step S5 it is checked whether there is any key input, and if there is no key input, the process returns to step S4 and the calendar is displayed. If there is a key input in step S5, the process advances to step S6 and the input key is ED.
It is checked whether the IT key 32 is input or not. When inputting the EDIT key, set the FS flag to °°0 in order to be able to change the year, month, and day input data set in the RAM24.
Then, the process returns to step SL. And the FS flag is °
Since it is "0", the year, month, and day change processing in step 59 and subsequent steps is executed.

If the EDIT key 32 is not input, step S6
The process then proceeds to step S7, where it is checked whether the MODE key 31 has been input. If the MODE key 31 is input, this is a request to change from the currently executed schedule/calendar display mode to a mode other than the calculator mode, so the FM flag is set to 1'' in step S8 and Stella 7' is input. Return to SL. Then step S1 to step S
Proceed to step 2 and perform normal calculator processing.

On the other hand, if it is determined in step S7 that the MODE key 31 is not input, the process proceeds to step 818, where it is checked whether or not the FF (4) key 11, which is a daily date update key on the DPK1O, is input, and the FF key 11 is input. In the case of , the process advances to step S19 and updates the data in the date register DATE by one day and advances the displayed calendar date by one day.
In the following step 522, the updated date is displayed on the display device 10a. For example, the calendar display shown in FIG. 6(A) becomes as shown in FIG. 6(B).

At this time, when the FF key 11 is pressed when ``rlQ December 31, 1984'' is displayed, ``January 1, 1985'' is displayed. Also, during leap years, calculations are automatically performed and updated. After that, the process returns to step S1.

If it is determined in step 518 that the FF key 11 is not input, the process proceeds to step 520, where it is checked whether the HEW ( ) key 12 is input. When inputting REV key 12, step 52
1, the data in the date register DATE is set back by one day, the date of the currently displayed calendar is set back by one day, and in the following step S22, the set back date is displayed. If you press the REW key 12 at the same time,
The calendar is displayed one day backward as shown in FIG. 6(A).

After that, the process returns to step 51.

At this time, as with the update process, leap year, year, and month transitions are naturally taken into account and the display is automatically backward displayed.

If the REW key 12 is not input in step 520, a separate processing routine for the schedule input state is executed, for example.

In this way, the display of the display device with a transparent keyboard (L
CD) By touching the transparent electrode above the letters, numbers, etc. displayed on the screen, you can operate this transparent electrode in the same way as turning over a normal daily calendar.
You can update and/or set back the date by one day,
It is possible to change the date using the same operation as the current calendar operation. Also, unlike calculators and personal computers, there is no need to set the date, change the date, or set the date each time. In addition, in the description of one or more of the present embodiments, a description has been added of a stroke method using a display device with a transparent keyboard, but it is possible to perform the same operation using a capacitive keyboard. As a daily calendar, “1 key (FF key)” and “- key (R
EW key)" is displayed, but this is not the only display format; any display format is fine as long as it is easy to understand updates and regressions.
Various applications are possible without departing from the spirit of the present invention.

〔effect〕

As explained above, according to the present invention, it is possible to easily update the date on a daily basis by simply inputting a specific key on the calendar display.
You can retreat.

In addition, the calendar date can be updated or set back by key input on the transparent keyboard located at the top of the calendar display means, allowing you to easily display the calendar date in the same way as turning over a wooden page or turning over a daily calendar. can be changed. Particularly when setting a schedule and inputting a schedule two days in advance, this can be done more easily with fewer key operations than the conventional method.
