Abstract

PURPOSE:To prevent troubles caused by the misoperation of other person by making an input from an input means impossible until the same password is inputted after the password is inputted by an input means. CONSTITUTION:The device is provided with an input means 1 that inputs characters, numerals, symbols, function keys, etc., a locking mode register 2 that stores the mode of propriety of subsequent input from the means 1, a password register 3 that stores passwords inputted from the means 1 and a locking mode switching means 4 that judges the propriety of input from the means 1 and switches the propriety of input mode according to the content of the register 2. By this constitution, input from the means 1 is made impossible until the same password is inputted after a password is inputted from the means 1, and thus, the breakdown of a document in preparation by the misoperation of others can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a word processor, and more particularly to a word processor that makes it possible to prevent erroneous operations by others during operation.

[Prior Art] Word processors used outside the user's room often have the chance of being mistakenly operated by someone other than the user. In particular, there are many cases where a user leaves his or her seat while creating a document, and it is quite conceivable that the document may be changed or lost due to an erroneous operation by someone else while the user is sitting down. If you are sitting in the middle of the day for a long time, it is natural to leave your seat after finishing the closing process or temporarily saving the created document to an external storage device, but if you are sitting in the middle of the day for a short time, Now, let's do the -1 termination process, temporarily save it to an external storage device such as a floppy disk,
It is extremely troublesome to read the document again and resume document creation after leaving the document unattended, and it often happens that the user leaves the document unattended and then realizes that an accident has occurred when attempting to resume inputting the document. Although high-end machines can use an external storage device with simple operations, low-priced models that do not have such a device require an inexpensive means to prevent such accidents.

[Problems to be Solved by the Invention] An object of the present invention is to provide an inexpensive and simple means for preventing accidents caused by erroneous operations by others during the above-mentioned operations.

[Means for Solving the Problems] In order to achieve the above object, the word processor of the present invention includes an input means for inputting characters, numbers, symbols, etc., and a mode for storing subsequent inputs from the input means. a locking mode register, a password register that stores a password input from the input means, and a locking mode register that determines whether or not input from the input means is allowed based on the contents of the locking mode register, and switches the input permission mode of the locking mode register. , and is configured such that after a password is input from the input means, no input from the input means is possible until the same password is input.

[Function] If you enter a password when an operation is interrupted, you will not be able to enter it until you enter the same password again, which prevents accidents such as the document being created being destroyed due to someone else's erroneous operation. can do.

[Examples] Examples of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an example of the configuration of a word processor according to the present invention. In the figure, l is an input means for inputting letters, numbers, symbols, function keys, etc., 2 is a locking mode register that stores the mode of whether or not subsequent inputs can be made from input means 1, and 3 is a password input from the input means. 4 is a locking mode switching means that determines whether input from the input means is allowed or not based on the contents of the locking mode register, and switches the input permission mode of the locking mode register.

FIG. 2 shows an embodiment of the word processor of the final IJJ. In the figure, 5 is a keyboard for inputting documents;
This corresponds to the input means 1 in FIG. For example, a keyboard with a JIS key layout is used.

Reference numeral 6 denotes a CPU (central processing unit) in the form of a microprocessor, for example, which constitutes the locking mode switching means 4 in FIG. 7 is a ROM, which performs various controls necessary for determining the locking mode register 2 and processing one character.
U control procedures, character font data, search tables, etc. are stored. A RAM (writable memory) 8 is used for storing and editing created documents, and is also used as various registers for control. The locking mode register 2 and password register 3 shown in FIG. 1 are stored in the RAM 8. 9.10 is an output device, 9 is a display device such as a liquid crystal device, and 10 is a printer as an example. The pass line 11 supplies control signals from the control unit to each circuit and device configuring the system,
It is also used for sending and receiving data.

Next, the operation of the word processor according to the present invention will be explained with reference to the signal processing flow diagram of FIG. In this flow diagram, the initial values of the locking mode register are release,
The initial value of the password input mode flag is OFF. Also, function keys (e.g. cursor movement keys, shift keys, etc.) can be used as password input instruction keys.
This is an example of setting an independent key as one of the
Of course, it is also possible to instruct password input using a combination of a plurality of arbitrary keys.

First, normal operations will be explained. Perform key human power of SL. Since the storage content of the locking mode register in step S2 is release, the process advances to step S3. If the input key is not a function key (normal operation (At))
, proceed to step S4. Since the password input mode flag is OFF, normal key manual processing in step S41 is performed and the process moves to the next key key input mode. If the input key is a function key (normal operation (A2)), STAY, PU S
3, proceed to step s5.

It is determined whether the input function key is a password manual instruction key. In this case, since it is a normal function key, the function key input process is performed in step S51, and the process moves to the next key manually.

If the operation is to be interrupted, the user presses the password instruction key and then inputs a password of a specific number of digits, about 5 digits 1n. When the function key, which is the password manual instruction key, is input, the memory content of the password register is l/leas, so the process goes from step S2 to step S53, and the S
From step 3, proceed to S5. In step S5, it is determined that the input function key is a password instruction key, and the process proceeds to step S52, where the password input mode flag is turned on to wait for password input (operation interruption (old)), and the process moves to the next input. When the password is entered manually, the process proceeds from steps S2 to 93 to step S4. Since the password manual mode flag is ON, the process proceeds to step S42.
Store the password in password register l. When all digits of the password have been stored, the lock mode is stored in the locking mode register (step 543), and the password input mode flag is turned off in step S44 (operation interruption (82)). This operation can prevent 19 accidents such as destruction of documents due to erroneous operations by others while the user is away.

When the key input (Sl) is performed with the password input, the memory content of the locking mode register is low 7, so the process advances from S2 to step S6, where it is determined whether the input key is the password, and the password is If not, the process advances to step Sil+, and subsequent key operations are disabled (unavailable for use by others (C)). Therefore, it is impossible for someone who does not know the password to enter the key manually, and no accidents will occur.

Enter the password to resume the interrupted operation. Since the content stored in the locking mode register is locked, the input is successively compared with the password stored in the password register in step S6. If even one character is input that differs from the password, the process moves to step 5f31, and subsequent keystrokes are disabled. At this time, the contents of the locking mode register remain locked. When all the specified passwords have been input, the process proceeds to step S62, stores the release mode in the locking mode register (operation i1f open (D)), and moves on to the next input.
Subsequent key personnel will be processed normally.

[Effects of the Invention] As explained above, according to the present invention, while the direct user of the word processor temporarily suspends the use of the word processor, it is possible to prevent others from inadvertently using the inexpensive and easy-to-implement means. By performing key operations, it is possible to prevent an accident in which the document being created is destroyed.
