Abstract

PURPOSE:To surely hold the documents under editing by using a password to permit the application only to the person in question. CONSTITUTION:A 1st instruction means USEDK instructs the interruption of the processing. A setting means PASV set a password to release the interruption state set by the instruction of the means USEDK. Then an input means 6 inputs the character strings. Furthermore a deciding means 1 decides whether the character string inputted via the means 6 is coincident or not with the password set by the means PASV. A release means releases the interruption of processing instructed by the means USEDK when the deciding means 1 decides the said coincidence. In such a constitution, the interruption of processing is released only when the due password is received from the means 6. Thus it is possible to avoid such a case where the documents under editing are destroyed due to the operation of the relevant device carried out by an outsider.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document processing device, and more particularly to a document processing device that processes document creation and editing.

[Prior Art] When operating this type of device, it is often necessary to leave the location due to some external or internal factor.

In such a case, if someone else starts operating the device without knowing, the document being edited will naturally be destroyed. This kind of trouble often occurs especially in offices where the absolute number of users is large compared to the number of installed devices.

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned problems. The purpose is to provide a processing device.

[Means for Solving the Problem] A document processing device of the present invention that solves this problem has the configuration shown below.

A document processing device that performs processing related to document creation and editing includes a first instruction means for instructing interruption of the processing, and when interrupting the processing according to an instruction from the first instruction means, the interruption state is a setting means for setting a password for unlocking; an input means for inputting a character string; and a determining means for determining whether the character string input by the input means corresponds to the password set by the setting means. , when the determining means determines that the character string and the password correspond,
and canceling means for canceling the interruption of the processing instructed by the first instruction means.

[Operation] In the configuration of the present invention, document creation and editing processing is prohibited unless a character string corresponding to the password set when interrupting processing is input. In other words,
By inputting and closing the corresponding password using the input means, the process is interrupted or canceled.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

<Description of Device Configuration (FIG. 1)> FIG. 1 is a block configuration diagram of a document processing device in an embodiment.

In the figure, 1 is an MPU that controls the entire device, and 2 is a ROM that stores the control processing procedure (program). Incidentally, this ROM 2 stores programs related to flowcharts shown in FIGS. 4 to 6, which will be described later. 3

is provided. Note that the purpose of use of these DBSV and PASV will be described later. Reference numeral 4 denotes a document memory in which document information being edited is stored. 5 is a cursor register that stores information on the position of the cursor in the editing screen,
The upper left of the display screen is set as the origin, and its horizontal (X direction) coordinate position is stored in XCREG, and its vertical (Y direction) coordinate position is stored in YCREG. In other words, changing the display position of the cursor can be achieved by changing the data to these XCREG and YCREG. Furthermore, in this case, when data exceeding the display screen size is stored, the cursor is not displayed. Reference numeral 6 denotes a keyboard for inputting various data (character data, editing instructions, etc.), and in particular, in the embodiment, it is provided with a key (USEDK) for instructing that the keyboard is in use and a key (EXEK) for instructing execution ( (Details of these will also be described later). 7 is a character generator (hereinafter referred to as CG) that generates a character pattern corresponding to the character code, and 8 is a display device (hereinafter referred to as CRT). Reference numeral 9 denotes a CRTC that performs a series of processes to generate a pattern based on the character code developed in the document memory 4 using the CG 7 and display it on the CRT 8.

Each of the above-mentioned components is a control lot 10,
They are electrically connected via a data bus 11 and an address bus 12.

Description of Processing Contents (FIGS. 2 and 3)> An overview of the processing of the document processing apparatus of this embodiment with the above-described configuration will be described below.

Prior to the following explanation, in order to facilitate the explanation of this embodiment, the document memory 4 has a character storage capacity of 10 digits x 6 lines, and the CRT 8 has a display capacity of 10 digits x 6 lines. Characters shall be displayed. That is, document memory 4 and CR
It is assumed that there is a one-to-one correspondence with T8. Therefore, now
If characters (actually character codes) as shown in FIG. 2 are stored in the document memory 4, they will be displayed on the display screen of the CRT 8 as shown. Also, the displayed 20 superimposed on the 6-digit, 4-line character `` or J'' on the display screen is a cursor, and this is in the cursor register 5 (7).
XCREC, 1, m"6°" This is achieved by storing the parameter 4° in YCREG.The display of the cursor is also naturally controlled by the CRTC9.

Now, with such a relationship between the document memory 4 and the CRT 8, when the operator leaves his/her seat in the display state shown in the figure, the operator presses the USEDK key in the keypad. After this, the user enters a password and leaves his/her seat, but in this embodiment, the device becomes inoperable unless the same information as the password is entered.

Specifically, when the press of the USEDK key is detected, the MP
The UI temporarily stores the information in the document memory 4 in the D in the RAM 5.
After evacuating to BSV, a display as shown in FIG. 3(a) is displayed. Of course, to display this, expand the corresponding character code in the document memory 4 and change the contents of the cursor register 5 (XCREG to '2' and YCREG to '4'). It is possible to perform a display as shown in the figure.The numerical values outside the display screen shown in the figure are for specifying the position on the display screen, and are not actual values.

Thereafter, the operator looks at this display screen and enters the password in the square brackets. After that, the password is confirmed by pressing the EXEK key. When the MPU 1 detects the pressing of this key, the character string in the square brackets, that is, the address A (n, 4) (2
≦n≦9) is saved in the PASV in the RAM 3, and the display shown in FIG. 3(b) is performed.

When the user returns to his/her seat, the user first presses the USEDK key to display the display screen shown in FIG. 3(C), and then inputs the password in accordance with the procedure described above. Then, only when the password previously saved in PASV and the password entered this time match, the DBS
The document information saved in V is transferred to the document memory 4 so that editing processing can be continued.

Explanation of the processing procedure (Figures 4 to 6) Based on the principle of the above-mentioned embodiment
It is shown in FIGS. 6 to 6 and will be explained below.

FIG. 4 is a flowchart showing the main processing contents in the embodiment.

As shown in the figure, key input (step SL) is determined (step S2), and when a key input other than the in-use instruction key (USEDK key) is made, various corresponding processes (document editing, etc.) are executed (step S3). )do. During this time, U.S.
When it detects that the EDK key is pressed, the message ``in use'' is displayed.
A process is performed to notify that this is the case and to prohibit the operation by a third party (step S4).

Hereinafter, the processing contents of step S4 will be explained in more detail according to the flowchart of FIG. 5 (the explanation of the processing of step S3 will be omitted since it is inconsistent with the spirit of the present invention).

When the depression of the USEDK key is detected, first, in step S20, the document information in the document memory 4 is saved (evacuated) to DBSV in the RAM 3. And step S2

2°.

Store 4°° in YCREG. Next, step S22
In step S23, the input password is stored in the PAS in RAM3.
Let V memorize it. Thereafter, in step S24, a message indicating that the device is in use is displayed as shown in FIG. 3(b), and then in step S25. At S26, the process waits until the USEDK key is input. When this key input is detected, a password confirmation screen is displayed (Figure 3 (C)!
(see step S28) and enters a password in the next step S28. In this way, in the next step 829, it is determined whether the password input here matches the password previously saved in the PASV. Here, if these passwords do not match, the process returns to step S24. On the other hand, if the password entered in step S28 matches the password saved earlier, it can be recognized that the user is the person himself/herself, and the process proceeds to step S30, where the DB
Recall the document information saved in the SV to the document memory 4,
Return to the previous main routine.

In other words, it becomes possible to continue the editing process.

Here, the same subroutine is used for the passwords in step S22 and step S30, a specific example of which is shown in FIG. 6 and described below.

First, a key input is performed in step S31, and the input key is determined in the next step S32. If it is determined that it is a character key, in step S33, the character code corresponding to the input key is stored in the position of the document memory 4 indicated by the cursor register, and the character pattern is displayed. Thereafter, the process advances to step S34, and the cursor 20 is moved to the next character display position. Specifically, a process is performed to increment XCREG in the cursor register 5 by 1 (however, if XCREG is already '9' (
(the rightmost part inside the square brackets), no further updates are made). This process is repeated to create a password, but during this time the execution key, that is, the EXE
When the press of the K key is detected, the process returns from this process.

Furthermore, if the input key is not a character key or an EX or EK key, it cannot be used as a password, so the key input is invalid.

As explained above, according to this embodiment, if you temporarily leave your desk while editing a document, use by a third party is prohibited, so it is possible to reliably retain the document being edited. In the embodiment, the document memory has the same shape as the display screen, but the present invention is not limited to this.

For example, it is conceivable to prepare a separate memory for creating a larger document and transfer only the display area to the document memory 4 of the embodiment.

Further, although the input characters are displayed on the display when entering the password, it is perfectly possible to not display them.

Furthermore, in Example C, the only characters that can be input are passwords, but if the input is divided into the user's name and password, the identity of the user can also be displayed.

[Effects of the Invention] As explained above, according to the present invention, even if you temporarily leave your desk while editing a document, it is possible to prohibit anyone other than the user from using the document. It is possible to hold it securely.

If the use is prohibited, it will be notified to that effect.
It is possible to know that before operating.
