Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a schedule display device for storing schedules for meetings, outings, etc., and for recalling and displaying the schedules.

[Prior art and its problems] Conventionally, the date and time of meetings and outings, as well as their items, are memorized.
There is now a schedule display device that can be called up and displayed at will. This type of device displayed, for example, "8/10 10:00 MEETING" and was capable of storing multiple pieces of such schedule data.

However, in the conventional schedule display device, schedules that are to be kept secret and schedules that are not are displayed indiscriminately, so there is an inconvenience that other people may find out the secret schedule when the person in question is not present.

[Objective of the Invention] This invention was made in view of the above circumstances, and an object of the present invention is to provide a schedule display device that does not display schedules that are to be kept secret, and that allows connections between a series of schedules to be understood. shall be.

[Summary of the Invention] In order to achieve the above object, the present invention stores schedule data and a secret code indicating that the schedule data is secret data in a storage means, and in a normal display mode, the secret data is not displayed. The key point is that mask data is displayed instead.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a circuit block diagram of a schedule display device according to an embodiment. Reference numeral 1 denotes a key input section, and includes various keys, such as a mode key (not shown) for setting the registration/display mode of the schedule device. ,
Character key 1a, number key 1b, function key 1c, scroll keys 1d, 1e, secret key 1
f, a mark key 1g, a clear key 1h, a schedule key 1i, a calendar key 1j, etc.

The control section 2 controls the operation of the entire apparatus according to data input from the key input section 1, and is connected to a schedule search section 3, a schedule control section 4, and the like.

The schedule search unit 3 operates in the schedule display mode, and receives a search command from the control unit 2 and a calendar designation unit 5 from the control unit 2.
The schedule storage unit 10 is searched in response to a search start address given via the search start address, and the results are sent back to the control unit 2.

The calendar specifying section 5 gives a search start address to the schedule search section 3 and accesses the calendar ROM 6, and the calendar ROM 6 sends the calendar data of the period (here, the month) specified by the calendar specifying section 5 to a character generator.
The character generator CG7 sends the corresponding calendar display pattern data to the display buffer 9 for the display section 8 (here, including a liquid crystal display and a controller) according to the control signal given from the control section 2. Display buffer 9 (here, a display with the capacity of one screen of the display section)
RAM) takes in the data sent to the location specified by the control unit 2.

The schedule control unit 4 is the schedule storage unit 1
0 and the content data storage unit 11. In the registration mode, the schedule storage unit 10 and the content data storage unit 11 are accessed in accordance with the schedule data and registration command given from the key input unit 1 via the control unit 2. Write control.

For convenience of explanation, the schedule storage unit 10 will be described here.
The data written in the content data storage unit 11 is shown in A in FIG. 2, and the data written in the content data storage unit 11 is shown in A in FIG.
Shown below. As you can see from A in Figure 2, area a
The date data of the schedule is stored in area b, the time data of the schedule is stored in area c, and the address of the content data storage unit 11 allocated at the same time is stored in the area c. The content data of the schedule is stored in the designated location (see A in FIG. 3). Furthermore, area d is a storage area for specifying whether or not the content data assigned to each time data is data to be kept secret, that is, secret data. In the case of secret data, a secret code S is stored. (This is set by using the secret key 1f of the key input unit 1). Furthermore, area e is a storage area that specifies whether the content data assigned to each time data is data that needs to be saved, that is, saved data, and if it is saved data, the code M of the indelible mark is specified. is stored (this is set by using the mark key 1g of the key input unit 1).

Now, returning to FIG. 1, other functions of the schedule control section 4 will be explained. In the schedule display mode, the schedule control section 4 performs control depending on whether or not the secret flag section 12 is reset. If it has been reset (meaning that the secret is secured), the schedule storage unit 1 checks whether the content data read from the content data storage unit 11 is secret data.
A determination is made based on whether or not a secret code S from 0 is detected, and if it is determined that the data is secret data, the display mask section 13 is instructed to mask the secret data. If the secret flag section 12 is set (meaning release of the secret), such release is performed by the key input section 1.
(by inputting a secret number using the secret key 1f and numeric key 1b), the schedule control unit 4 converts the data read from the schedule storage unit 10 and content data storage unit 11 into the schedule format without outputting a mask command. It is synthesized and outputted, passes through the display mask section 13, and is supplied to the character generator CG14.
This character generator CG14 is the controller 2
The display buffer 9 is supplied with corresponding schedule display pattern data in accordance with control data inputted from the display buffer 9.

Furthermore, in the schedule clear mode (designated by operating the clear key 1h of the key input section 1), the schedule control section 4 clears the schedule storage section 10 and content data storage according to the clear command given from the control section 2. The schedule data contained in part 11 is to be erased, but the code of the non-erasable mark M (see A in Figure 2)
Schedule data related to this will be saved without being deleted.

Next, the operation of the apparatus having the above configuration will be explained.

Registration of schedule data First, set the device to registration mode using the mode key (not shown). And calendar key 1j, schedule key 1i, number key 1b, character key 1
Enter the date, time, and content data of the schedule using a. As a result, the schedule control section 4 receives the registration command and schedule data including date, time, and content from the control section 2, and controls write access to the schedule storage section 10 and content data storage section 11. In this case, when entering data that the user wants to save, that is, schedule data that he does not want to delete, he must press mark key 1.
g, and also operates the secret key 1f when inputting data to be kept secret. This information is also written into the schedule storage section 10 via the control section 2 and schedule control section 4. As a result, the schedule storage section 10 stores data as exemplified by A in FIG. 2, and the content data storage section 11 stores data as exemplified by A in FIG. 3.

Erasing schedule data This operation is not directly related to this invention, so only the results will be explained. That is, when the schedule data is deleted, only the data with the non-erasable mark M is left in the contents of the schedule storage section 10 and content data storage section 11 (A in FIG. 2 and A in FIG. 3). , as shown in B of FIG. 2 and B of FIG.

Calendar Display (Reservation Display) Since this operation is not directly related to this invention, only the results will be described. That is, FIG. 5 shows the content displayed on the screen of the display section 8 as a result of this operation, and it shows the content displayed on the screen of the display section 8, which was created through the calendar specification section 5.
On the monthly calendar, the presence or absence of reservations obtained through the schedule search unit 3 is displayed in segments, including the morning of August 1st, the afternoon of the 12th, the morning and afternoon of the 22nd, and the morning of the 26th. It shows that there is a reservation for the afternoon.

Furthermore, Figure 6 shows a calendar display of the schedule data for August 1986 after the schedule data has been deleted as described above, and it can be seen from this figure that only the saved data related to the indelible mark M is left. It can be seen that

Schedule data display (Figure 4 A and B, Figure 7)
(Figure) First, a display mode is specified using a mode key (not shown). Next, if the user wishes to release the secret, he operates the numeric key 1b (for inputting the secret number) and the secret key 1f; otherwise, this operation is not performed. As a result,
Only when a correct secret number is input, the secret flag section 12 is set and the secret is set to be released. Finally, when the number key 1b (to specify a date, for example, August 22, 1986) and schedule key 1i are operated, the operation shown in FIG. 7 is started.

That is, the schedule control section 4 receives an instruction from the control section 2 to display the schedule data for the designated day, and
Schedule storage unit 10 and content data storage unit 11
is accessed and the first data of the schedule data for the designated date, August 22, 1986 (the data at the top of FIG. 2A) is imported (step A30). Next, the schedule control section 4 checks the contents of the secret flag section 12 and determines whether the secret has been released (step A31). If the code has not been released, it is determined whether or not the code read from area d of the schedule storage section 10 is a secret code (step A32). in this case,
As you can see from Figure 2 A, the first data does not have a secret code, so step A34
jump to. Here, the schedule control unit 4
In order to write the fetched schedule data to the display buffer 9, it instructs the control unit 2 to specify a control signal in the character generator CG14 and an address in the display buffer 9, and writes the schedule data in a predetermined order (as instructed by the control unit 2). The schedule data is outputted at the location specified by the control section 2 (order), and the data passed through the display mask section 13 and converted into a display pattern by the character generator CG14 is sent to the display buffer 9. In this case, the data sent to a predetermined location in the first stage of the buffer is fetched (step A34).

Next, the schedule control section 4 controls the display buffer 9.
It is determined whether the data written in is the data of the fourth stage (step A35). In this case, the written data is 1986 8 in the schedule storage unit 10.
Since this is the first row data for the 22nd of the month (see Figure 2 A), increment the address by 1 (step
A36) Import the second stage data for August 22, 1986 in the schedule storage unit 10 and the schedule data in the related content data storage unit 11 (step
A30). From now on, the operation is repeated in the same way, but in this example (when displaying the schedule data for August 22, 1986 without releasing the secret), the secret code S is added to the third row of data. is assigned (see Figure 2A). Therefore, it is determined in step A32 that this data has a secret code. Therefore, the schedule control section 4 outputs a mask command to the display mask section 13 (step A33), and the display mask section 13 masks the content data sent from the schedule control section 4, in this case, the code of "Seisankaigi". Then, the character generator CG14 is addressed to output a mask pattern (* in this case). As a result, the third row of the display buffer 9 shows * as shown in FIG.
＊＊＊＊ is written in the content data location. Finally, if it is determined in step A35 that the data is the fourth stage data, execution of the schedule data display command is completed, and at this time, the screen of the display section 8 displays the format shown in A of FIG. Schedule data is displayed.

If the secret flag section 12 is set, that is, if the secret is released, the determination result in step A31 is YES, so the machine program proceeds to step A24 without applying a mask command to the content data. The schedule data is written in the schedule format at a predetermined position in the display buffer 9.

FIG. 4B shows the contents displayed on the screen of the display unit 8 as a result of executing the display command in the secret release mode for the schedule data of August 26, 1986.

As can be seen from FIG. 2A, five stages of data for August 22, 1986 are stored in the schedule storage unit 10, so if you want to see the data in the fifth stage, press the key input unit 1. scroll keys 1d, 1
It is best to operate e. Feed scroll key 1e
When you press once, the control section 2 switches to the schedule control section 4.
The display command shown in FIG. 7 is executed by incrementing the top address to be accessed by one. As a result, 10:00 in the second row of Figure 4
The display content of "Hanbaikaigi" moves to the top row,
Similarly, the third stage becomes the second stage, the fourth stage becomes the third stage, and the fifth stage appears in the fourth stage, which is the lowest stage of the scheduled format area.

Although it is not specified in Figure 7, if there are no four rows of reservation data on the specified date,
For example, if there are only three steps,
When the fourth row is read from the schedule storage section 10 at A30, the date data is data for a date after the specified date, so this is detected and the execution of the display command is ended.

[Modifications] This invention is not limited to the above embodiments, and various modifications and changes can be made without departing from the scope of this invention. For example, in the above embodiment, the schedule data specified by the secret code S, that is, the secret data (time data and content data)
Of these, only the content data can be masked, but it is also possible to mask the time data (in the case of A in Figure 4, 13:45 *
(Mask with **). In this case, the secret time period will also become invisible, but the connections between the schedule data as a whole can be grasped.

Furthermore, the method of masking is not limited to *, but any method may be used as long as the secret data is not visible (for example, a simple blank display or scrambled data display).

[Effects of the Invention] As explained in detail above, the present invention provides a system for displaying a series of schedule data (for example, one day's worth of data) on the display unit, when the series of schedule data becomes secret data. According to the mode specified by the above-mentioned mode specifying means, the output is controlled only for the data that is displayed, masked in the normal mode, and unmasked in the cancel mode, so that the connections and relationships between the displayed schedule data are controlled. It is easy to understand and can protect confidentiality without compromising the scheduler's function, which is highly effective.
