Abstract

PURPOSE:To reduce the accident of erroneous data input to a data base, etc., by perform the lock/unlock of a key input state by depressing a dedicated key on a keyboard or performing a series of data input. CONSTITUTION:A key input lock/unlock mechanism 5 is comprised of a storage part 6, a time monitoring part 7, and a control part 8. The key input lock/ unlock mechanism 5 locks key input by performing a series of key input set in advance, and a mechanism to lock the key input is operated when no key input is performed within preset time. Also, the key input lock/unlock mechanism 5 unlocks the key input by performing the depression of the dedicated key 2a or a series of key input set in advance. Thereby, it is possible to prevent erroneous data inputted due to the accidental depression of a key by locking the key input while an operator is absent, and also, to lock the key input even when the lock designation of the key input is forgotten, which prevents the erroneous data being inputted accidentally.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention prevents erroneous data input due to accidental key presses caused by objects, people, etc. around the keyboard when inputting data from a terminal device. This invention relates to a method for preventing erroneous data input.

[Conventional technology]

Conventionally, as described in Japanese Patent Laid-Open No. 63-19029, a data input method using a keyboard is equipped with at least two sets of keyboards that occupy one set of display units and allow a series of tasks to be performed while interacting with the display. In terminal devices, each keyboard has a dedicated key, allowing dedicated key input in the initial screen state and switching keyboards, and prohibiting proprietary key input on other keyboards while inputting data on a keyboard that is permitted to be used. However, there is also a keyboard switching method that allows continued use as is.

[Problem to be solved by the invention]

When inputting data, the above conventional technology prevents erroneous data input due to accidental key presses while the input worker is thinking, or objects around the keyboard or accidental key presses by other workers while the input worker is away. No consideration was given to the possibility of erroneous data input, and there was a problem in which erroneous data that was not intended by the input operator was input without being noticed.

An object of the present invention is to prevent erroneous data input due to accidental key presses while an input worker is not engaged in input work.

[Means to solve the problem]

In order to achieve the above object, the erroneous data input prevention method of the present invention includes a mechanism for locking and unlocking key input;
This terminal device is provided with a mechanism that locks key input when there is no key input within a preset time.

[Effect]

The key input lock/unlock mechanism locks key input by pressing a proprietary key or by inputting a preset series of keys. As a result, data input by pressing keys is prohibited, so incorrect data will not be input due to accidental key presses by objects or people around the keyboard, and if there is no key input within a preset time, key input will be disabled. The locking mechanism operates. As a result, data input by pressing a key is prohibited after a certain period of time even when the input worker starts thinking or leaves his/her desk, so that incorrect data will not be input due to an accidental key press. The key input lock/unlock mechanism unlocks key inputs by pressing a proprietary key or by inputting a preset series of keys.

〔Example〕

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

FIG. 1 is a block diagram showing the overall configuration of an embodiment of the system of the present invention.

The terminal control unit 1 includes a keyboard 21, a display device 3, and 2, 3.
In addition to the input/output control unit 4 that controls each device, the keyboard 2
It is comprised of a key input lock/unlock unit 5 that locks or unlocks key input from.

FIG. 2 is a block diagram showing the configuration of the key input lock/unlock section 5. As shown in FIG.

The key input lock/unlock section 5 includes a storage section 6, a time monitoring section 7, and a control section 8. The control unit 8 locks or locks key input from the keyboard 2 when a dedicated key 2a provided on the keyboard 2 is pressed or a series of key inputs that match data (keywords) set in advance in the storage unit 6 are made. Perform the cancellation. The time monitoring section 7 measures the time when the key input is interrupted, and when the time exceeds the time preset in the storage section 6, it issues a control signal to the control section 8 to lock the key input from the keyboard 2.

FIG. 3 is an operation flow diagram of the key input lock/unlock section 5. As shown in FIG.

When there is a key input (301), the control unit 8 determines whether it is a press of a proprietary key or a series of key inputs that match data (keywords) set in advance in the storage unit 6 (302).
)I do. If the determination (302) is YES, then it is determined whether the designation by the key input (301) is a lock designation (
303). In this embodiment, when the proprietary key 2a is pressed or there is a key input that matches preset data, if the key input state is already locked, it is determined to be unlock designation, and if it is unlocked, it is determined to be lock designation. do. If this judgment (303) is YES, key input is locked (
304), and if NO, release the key input lock (3
05).

If the above process (304) or (305) is completed, or if the determination (302) is No, then a determination (306) is made as to whether the key input state is in the locked state. If the determination (306) is YES, the process returns to key input (301). Judgment (306
) is No, then it is determined whether the key input (301) is within a preset time (307). If the judgment (307) is YES, normal input/output processing (309)
and waits for the next key input (301). Judgment (307)
If is NO, lock key input (308) L, judgment (
Return to 306). Since this determination (306) is YES, the process returns to key input (301) and waits for the next key input.

FIG. 4 is a diagram showing an example of the arrangement of the proprietary keys 2a. Exclusive keys 2 can be placed on the side or back of the keyboard.
Prevent accidental pressing of a as much as possible. Furthermore.

In determining whether or not the proprietary key 2a has been pressed (302), it is determined that the proprietary key 2a has been pressed only when the pressing of the proprietary key 2a is repeated three or more times in three seconds, for example. It is no longer possible to distinguish between an accidental key press and an intentional key press by an input worker, resulting in a malfunction.

According to this embodiment, when the input worker leaves his/her seat.

By pressing the exclusive key 2a or performing a series of key inputs and locking key inputs, it is possible to prevent erroneous data input due to accidental key presses by objects or people near the keyboard while the user is away from the keyboard. In addition, even if the input worker leaves their desk, forgets to lock key input, or is immersed in thought for a long time while inputting, the system will detect that no key input has been made within a preset time. However, since key input can be locked, it is possible to prevent erroneous data input due to accidental key presses by objects or people near the keyboard.

〔Effect of the invention〕

According to the present invention, the key input state can be locked/unlocked by the data input worker pressing a dedicated key on the keyboard or by inputting a series of data.
It is possible to prevent erroneous data input due to accidental key presses by objects or people near the keyboard when the input worker is absent, and has the effect of reducing accidents of erroneous data input into databases and the like. In addition, even if the input worker forgets to lock key input when away from the desk or is immersed in thought, the system will detect that no key input has been made within a preset time and lock key input. This has the effect of reducing input workers' concerns about preventing erroneous data input in an environment where terminal devices are continuously operated.

This is especially effective in environments such as databases where large amounts of data are entered by many people over long periods of time.
