BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creation device, and more particularly to one in which a password for accessing a data memory corresponding to a plurality of function modes is shared.

0002

[Prior Art] Conventionally, word processors for European languages and Japanese word processors have been provided with many functions such as document creation/editing functions, address book creation functions, and schedule functions. In order to classify and store input file data, a plurality of types of data memory, such as a text memory and an address book memory, are provided in the control device in correspondence with each of these many functions.

[0003]Recently, when a password is set in advance for each file data stored in each data memory, and the corresponding data memory is accessed in each function mode, this preset password is compared with the input password. The file data can be displayed on a display or printed on a printing paper only when both passwords are the same, thereby maintaining the confidentiality of the file data.

0004

[Problems to be Solved by the Invention] As mentioned above, in a word processor that verifies a password when accessing each data memory, the confidentiality of each file data is maintained. A password setting operation is required each time a data memory is stored, and a password must be entered each time the data memory is accessed, making the operation complicated. There are problems such as an increase in memory capacity for storing passwords. Furthermore, since a different password is set for each data memory, for example, it is necessary to manage the password by writing a memo that associates the name of the data memory with the password.

[0005] An object of the present invention is to provide a document creation device in which only one set of passwords for accessing each of a plurality of types of data memories is commonly set, thereby simplifying the password setting operation. be.

[0006]

[Means for Solving the Problems] A document creation device according to the present invention includes an input means for inputting character and symbol data and various command signals, and a plurality of input means for storing data inputted from the input means. In order to access multiple types of data memories by storing multiple types of data memories corresponding to multiple function modes and one set of input character strings in the password memory. a password setting means that is set as a common password for each function mode, and a password input for accessing the corresponding data memory in each function mode and a password stored in the password memory are verified to be the same;
and password verification means that permits access to the data memory only when both passwords are the same.

[0007]

[Operation] In the document creation device according to the present invention, data input from the input means in each function mode is stored in the data memory corresponding to the function mode, and the password setting means stores the input set of character strings. The password is stored in the password memory and set as a common password for accessing multiple types of data memory. On the other hand, the password verification means verifies whether the password input to access the data memory corresponding to each function mode is the same as the password stored in the password memory, and determines whether both passwords are the same. Allow access to that data memory only when.

[0008]

According to the document creation device according to the present invention, a plurality of types of data memories, a password setting means, a password verification means, etc. are provided, and one set of passwords stored in the password memory can be stored in each of the plurality of types of data memories. Since the files are shared so that each file data stored in the data memory can be accessed in common, the password setting operation and the access operation to the data memory can be greatly simplified while maintaining the confidentiality of each file data stored in the data memory. Furthermore, since there is only one set of passwords, there is no need to manage passwords, and the memory capacity of the memory for storing passwords can be significantly reduced.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings. This embodiment is a case in which the present invention is applied to an English word processor that is equipped with a document creation/editing function, an address book function, a schedule function, a communication function, etc., and a password can be set. As shown in FIG. 2, a keyboard 3 is disposed at the front of the body frame 2 of the word processor 1, and a daisy-wheel type printing mechanism PM is disposed within the body frame 2 behind the keyboard 3. A liquid crystal display 10 capable of displaying 14 lines of characters and symbols is provided at the rear of the machine.

The keyboard 3 displays character keys including alphabet keys, numeric keys, and symbol keys, a space key, a return key, cursor movement keys for moving the cursor on the display 10 in up, down, left, and right directions, and an auxiliary menu. A menu key for editing, an end key for ending various editing functions, and other function keys are provided in the same manner as in normal ones. The printing mechanism PM has a general configuration including a platen, a carriage, a daisy wheel, and the like.

Next, the control system of the word processor 1 is shown in FIG.
It is configured as shown in the block diagram. Display mechanism D
M is a general-purpose display controller 11 that includes a liquid crystal display 10, a display RAM for outputting display data to the display 10, and a character generator ROM that stores a large number of dot pattern data such as characters and symbols. It is of composition. Incidentally, reference numeral AM designates an alarm mechanism that includes a buzzer 12 and a drive circuit 13 that causes the buzzer 12 to sound.

The control device C is composed of a CPU 16, an input/output interface 14 connected to the CPU 16 via a bus 15 such as a data bus, a ROM 17, and a RAM 20. Although not shown, the control device C includes a timekeeping element (real time clock element) that is backed up by a lithium battery and outputs a real-time time signal including date and time to the input/output interface 14. , a communication interface for data communication with electronic devices such as external word processors and personal computers.

A ROM (program memory) 17 includes a display control program that controls the display mechanism DM in response to code data input from the keyboard 3, and the code data is stored in a text memory 22 via a line buffer 21.
A control program that stores file data in data memories such as the address book memory 23 and schedule information memory 24, a print control program that controls the printing mechanism PM in correspondence with file data in the data memory, and multiple programs displayed on the main menu. Control programs for each of the functional modes, a control program for password verification control to be described later, and the like are stored.

Here, as shown in FIG. 8, for example, the main item number "1" is a function for inputting and editing document data to the text memory 22, as a plurality of function modes displayed on the main menu. Main item number ``2'' is the address book creation function, main item number ``3'' is the schedule function, main item number ``4'' is the spreadsheet function,
Main item number “5” is the print function, main item number “6”
" is a calculation function, main item number "7" is a time setting function,
Main item number “8” is communication function, main item number “9”
" is a facsimile transmission function, and main item number "0" is a function to access file data on a floppy disk.

The line buffer 21 of the RAM 20 stores one display line of data including the cursor input from the keyboard 3 and displayed on the display 10, or a multiple line file read from the data memory and displayed on the display 10. Of the data, one display line of data including the cursor is stored. The text memory 22 receives one line of data from the line buffer 21 one after another and stores document data. In the address book memory 23, "name"
, "address,""telephonenumber,""facsimilenumber," and the like, address book data is classified and stored for each address book. The schedule information memory 24 stores a large amount of input schedule information in association with calendar information.

[0016] In the character string memory 25, data of a set of character strings input when the password input screen is displayed is stored as an input password pw. The password memory 26 stores password data of a common password PW for accessing the text memory 22, address book memory 23, and schedule information memory 24. The counter 27 has a count value I ranging from "0" to
Either "2" is stored. In the flag memory 28,
The flag data of the password registration flag F1 is set (data is "1") when the password PW is stored in the password memory 24, and the flag data of the verification flag F2 is set when the input password pw and password PW match. flag data is stored.

Next, a password verification control routine performed by the control device C of the word processor 1 will be explained with reference to FIGS. 4 to 7. In addition, in the figure, Si (i=1, 2
, 3...) are each step. This control is started when the power switch is turned on, initial settings are first executed (S1), and the main menu is displayed. For example, Figure 9
As shown in the figure, ten function modes assigned to main item numbers "1" to "0" are displayed on the display 10. Here, when the menu key is operated (S3
- S4: Yes), an auxiliary menu consisting of a plurality of auxiliary items including "password" is displayed on the display 10 (S5). For example, as shown in Figure 8, "Password"
Four auxiliary items, including , are displayed on the display 10 overlapping the main menu. When the auxiliary item "Password" is selected from this auxiliary menu (S6
, S7: Yes), password processing control (see FIG. 5) is executed (S8). However, when an auxiliary item other than "password" is selected (S6, S7: No), the process of the selected auxiliary item is executed (S9).

[0018] When this password processing control is started,
A submenu having three subitems related to passwords is displayed on the display 10 (S20), "0" is stored in the count value I of the counter 27 (S21), and "
The first sub-item is displayed with the block cursor 30 based on the count value I of 0. For example, as shown in Figure 8, there are three sub-items related to passwords: "Password Registration"
, "Password change" and "Password release" are each displayed in English, and "Password registration" displayed at the top is displayed with a block cursor 30.

Next, when the cursor down movement key is operated to select a desired sub-item (S23/S24:
If the count value I is smaller than "2" (S25: No), the count value I is incremented by one (S26), and the sub-items based on the count value I are alternatively displayed with the block cursor 30. (S27),
Return to S23. On the other hand, when the cursor down movement key is operated when the count value I is "2" (S23/S2
4.S25: Yes), return to S21. Then, when the return key is operated (S23: Yes, S24
: No, S28: Yes), password registration processing control (
(see FIG. 6) is executed (S29).

[0020] When this control is started, a password input screen is displayed on the display 10. For example, as shown in FIG. 9, a password input screen prompting the user to input a password is displayed. When a character key is operated to set one set of passwords as a character string (S41
S42: Yes), the input character string data is stored in the character string memory 25 as the input password pw (S4
3). However, this input character string is displayed on the display 10.
is not displayed. Then, when the return key is operated to set a password (S41: Yes, S42
:No, S44: Yes), and when the flag F1 is reset and the count value I is "0" (S45:
Yes, S46: No), the input password pw in the character string memory 25 is transferred to the password memory 26 and stored as the password PW (S47), the flag F1 is set (S48), and the process returns.

However, when the count value I is "1" when the return key is operated, that is, when changing the password (S45: No, S50: Yes), and when the input password pw and the password PW are the same (S51 :Y
es), the count value I is set to "0" and the flag F1 is reset (S52), and a message prompting the input of a new password is displayed on the display 10 (S5
3) Returning to S41, a new password setting is executed. On the other hand, when the return key is operated, the count value I
is "2", that is, when releasing the password (S45
- S50: No, ), when the input password pw and password PW are the same (S54: Yes), the password memory 26 is cleared (S55), the flag F1 is reset (S56), and the process returns. In addition, Y in S46
If it is determined to be es, an error message indicating that the password has already been registered will be displayed again in S51 and S54.
If the determination is No, an error message indicating that the two passwords are different is displayed on each display 10.

By the way, when a desired function mode is selected by operating the numeric keys while the main menu is displayed (S3: Yes, S4: No, S10: Yes), the selected function mode is stored in the text memory 22 or When accessing a data memory such as the address book memory 23 or the schedule information memory 24 (S11: Yes), if the password PW is set in the password memory 26 and the flag F1 is set (S12: Yes), the password is Verification processing control (see FIG. 7) is executed to verify the information (S13). For example, as shown in FIG.
In the main menu displayed at 0, when a main item number other than main item numbers "5" to "7" is selected and a password is set, verification processing control is executed.

When this control is started, a password input screen is first displayed (S60), and the character data corresponding to the character keys operated to input the password are sequentially stored in the character string memory 25 (S61).・S62: Yes
, S63). Then, when the return key is operated (S61: Yes, S62: No, S64: Yes),
When the input password pw and the password PW are the same (S65: Yes), the flag F2 is set (S6
6), Return. However, if the two passwords do not match (S65: No), the flag F2 is reset (S67) and the process returns. And this flag F2
is set (S14: Yes), the selected function mode is executed. That is, when this functional mode is executed, access to a predetermined data memory is permitted. For example, as shown in Figure 9, main item number “1”
When the document creation function "" is selected and the input password pw and password PW are the same, access to the text memory 22 is permitted and this function can be executed. However, if the flag F2 has been reset (S14: No), an error message indicating that the passwords are different is displayed (S16). As explained above, one set of passwords stored in the password memory 26 can be accessed in each of multiple types of data memories, such as the text memory 22 and the address book memory 23, which are provided corresponding to multiple function modes. By making these common, password setting operations and file data access operations can be greatly simplified while maintaining the confidentiality of each file data stored in the data memory.

Furthermore, since there is only one set of passwords, there is no need to manage passwords, and the memory capacity of the password memory 26 for storing passwords can be significantly reduced.

Note that the password verification control may be partially changed so that only "password registration" and "password change" are enabled.

[0026] It should be noted that a Roman word processor, a Japanese word processor, and a Japanese word processor that are equipped with multiple types of data memory including text memory, etc., corresponding to multiple function modes such as a document creation function, an address book function, and a schedule function, respectively, and that can be configured with a password. Of course, the present invention can be applied to various document creation devices such as personal computers.
