Abstract

PURPOSE:To prevent a document or the like in editing from being destroyed even at the accurance of runaway in an input device by monitoring the abnormality of a keyboard by a keyboard interface and saving the document in editing by a CPU based upon an abnormality signal. CONSTITUTION:The keyboard interface 41 monitors whether abnormality occurs in the keyboard 42 or not, and when abnormality occurs, generates an abnormality signal 12 to control the interruption of the CPU 10. As an abnormality deciding method of the interface 41 abnormality is decided when a code sent from the keyboard 42 is other than a prescribed code and the signal 12 is sent to the CPU 10. In interrupting processing based upon the signal 12, keyboard inputs other than the signal 12 are inhibited to protect the editing document stored in a main memory 20 and an access to a floppy disk drive 62 or the like is inhibited to display abnormality and forcedly save the editing document and format stored in the main memory 20 to a temporary storage area in the drive 62.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creating apparatus such as a Japanese word processor, and more particularly, to a document being edited or a document stored in a storage medium being destroyed when the input device becomes abnormal. The present invention relates to a document creation apparatus that prevents a document being edited from being abandoned by automatically saving the document being edited to a storage medium such as a floppy disk.

[0002]

2. Description of the Related Art A conventional device, as disclosed in Japanese Patent Laid-Open No. 1-205225, sends a normal operation signal from a keyboard every time a predetermined number of key scans are made and determines whether or not the normal operation signal is sent. There has been a device that monitors every time and sends a reset signal to the input device to initialize the input device when a normal operation signal is not sent out, and recovers immediately after a runaway of the keyboard.

[0003]

In the prior art, it suffices to be able to recover by the reset signal, but there are cases where it cannot be recovered due to hardware failure or the like. In particular, if the input device malfunctions or goes out of control during document editing and cannot be recovered by the reset signal, it cannot be saved in a storage medium such as a floppy disk, and the document being edited must be discarded. In addition, the operation of the input device is not guaranteed due to the runaway of the input device, and the document being edited or the document stored in the storage medium may be destroyed.

An object of the present invention is to provide a document editing device which prevents destruction of a document being edited or a document stored in a storage medium even if the input device goes out of control and does not abandon the document being edited. To do.

[0005]

In order to achieve the above object, a storage medium such as a floppy disk is provided with a save area and an abnormality detecting means for detecting whether or not an input means such as a keyboard or a mouse is abnormal. Evacuation means for evacuating and storing in the evacuation area of the storage medium is provided, and when the abnormality detection means detects that the input means is abnormal, the document or figure being edited is saved in the storage medium by the evacuation means. It was done like this. Further, the input from the input means is not accepted until the abnormality notification from the abnormality detection means is canceled, thereby preventing the destruction of the document or figure stored in the storage medium.

In order to achieve the above object, a saving area is provided in a storage medium that can be taken out from the document creating apparatus, and when the abnormality detecting means detects that the input means is abnormal, the document being edited or Is for saving the figure in a storage medium that can be taken out by the saving means. As a result, even if the currently used document creating apparatus does not recover abnormally, another document creating apparatus can continue editing work.

Further, in order to achieve the above object, the image data is saved in a temporary storage area used during the editing work. This makes it possible to easily distinguish the saved document from other documents when the saved document is read into the document creating apparatus again and the editing work is continued.

Further, in order to achieve the above object, the abnormality detecting means detects whether or not the input means is abnormal every predetermined time, and when an abnormality occurs, the document being edited is saved in the saving means. The data is saved in the storage medium.

[0009]

[Operation] The input means consists of a keyboard, a mouse, etc.
Editing work such as inputting new documents and changing existing documents.
The storage means includes a storage medium such as a floppy disk and a floppy disk drive and a drive device for the storage medium, and saves the created document and reads the saved document. The editing means inputs and edits the document according to the instruction input from the input means. The display means is composed of a CRT or a liquid crystal display device, and displays a document being edited, contents of editing work, and the like. The abnormality detecting means detects whether or not the input means is abnormal at all times or at predetermined intervals, and when there is an abnormality, notifies the evacuation means that there is an abnormality. The save means saves the document being edited to a save area of a storage medium such as a floppy disk of the storage means when the abnormality detection means notifies the abnormality. Further, the input from the input means is not accepted until the abnormality notification output from the abnormality detection means is canceled. This prevents the document being edited and the document stored in the storage medium from being destroyed and prevents the document being edited from being abandoned even if the input device is out of control or malfunctions.

Further, the saving destination of the document or figure being edited is a storage medium which can be taken out from the document creating apparatus.
Even if the currently used document creating apparatus does not recover abnormally, it is possible to continue editing work with another document creating apparatus.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, 10 is a CPU, 20 is a main memory, 31 is a program ROM, 32 is a dictionary ROM,
33 is a font ROM, 42 is a keyboard, 41 is a keyboard interface circuit which is an input device, 52 is a CRT which is a display device, 51 is a CRT interface circuit, 62 is a floppy disk drive which is an external storage device, and 61 is a floppy disk. A drive interface circuit, 72 is a hard disk drive as a storage device, 71 is a hard disk drive interface, 82 is a printer as an output device, 81 is a printer interface circuit, 11 is each of the CPU 10 and the main memory 20, the interface circuit 41, etc. A bus connecting the devices, and 12 is an abnormal signal notifying that the keyboard 42 is abnormal.

The processing procedure is shown in the flowchart of FIG.

In the initial setting, the CPU 10 checks the operation of each device such as the main memory 20 and the floppy disk drive 62 based on the program in the program ROM 31 connected by the bus 11, and if normal, the initial setting is completed. To do. Next, CRT interface 51
The CRT 52 connected to is displayed as to whether or not to newly create a document, and one of them is selected from the keyboard 42. When creating a new document, a format is input from the keyboard 42 and written in the main memory 20 via the keyboard interface 41. When editing an existing document, the document and format to be edited are read into the main memory 20 from the floppy disk drive 62 via the floppy disk drive interface 61 or from the hard disk drive 72 via the hard disk drive interface 71. Next, use the keyboard 4 to register, edit, or print.
Select from 2. When registration is selected, the document and format in the main memory 20 are transferred to the floppy disk drive 62 via the floppy disk drive interface 61.
Alternatively, the document is registered in the hard disk drive 72 via the hard disk drive interface 71.
When editing is selected, the document in the main memory 20 is displayed on the CRT 52
Is displayed using the keyboard 42 for editing. When printing is selected, the document in the main memory 20 is output to the printer. To continue the work, select registration, edit, or print to perform the work. The font ROM33
The document in the main memory 20 has a character code, so it is used when developing it into image data.
When the data is displayed on T52 or printed on the printer 82, the expanded data is used. The dictionary ROM 32 is used for character conversion such as kana-kanji conversion during character input or editing. The above is the normal processing, but if the keyboard 42 breaks down here, it becomes impossible to input, the operation cannot be guaranteed due to runaway, the document in the main memory 20 is destroyed, and in some cases the floppy disk drive 62 or the hard disk drive 72. You may inadvertently access and destroy the registered document. Therefore, the keyboard interface 41 determines an abnormality, and when there is an abnormality, the abnormality signal 12 is generated and the interrupt control of the CPU 10 is performed. Keyboard interface 41
As a method of determining an abnormality in (1), when the code sent from the keyboard 42 is out of the predetermined code, it is determined to be abnormal and is sent to the CPU as an abnormality signal 12. The interruption processing in this prohibits the keyboard 42 input other than the abnormal signal 12 to protect the document being edited in the main memory 20,
Further, the floppy disk drive 62, the hard disk drive 72, etc. are prohibited from being accessed, a keyboard error is displayed on the CRT 52, and the document and the format being edited in the main memory 20 are forced into the temporary storage area of the floppy disk drive 62. I am trying to evacuate to. When the keyboard 42 breaks down, it often does not recover from the abnormal state. At this time, the abnormal state remains and other processing is not performed. However, there is a possibility of recovery from an abnormal state. Therefore, when recovery from an abnormal state is made, the normal state is restored and editing work is continued.

According to the present invention as described above, even if an input device such as a keyboard is in an abnormal state, the registered document is prevented from being destroyed and the document being edited is temporarily stored in a storage medium such as a floppy disk. Never abandon the document being edited.

Although a keyboard is used as an input device in the present embodiment, the present invention is not limited to this, and an input device such as a mouse can be easily implemented. Further, the save area is not limited to the temporary save area, and similar effects can be obtained as long as the save area is saved in the storage medium. Further, the storage destination of the edited document is preferably a storage medium such as a floppy disk that can be taken out from the document creation apparatus, but the storage destination is not limited to this, and the same effect can be obtained.

Another embodiment of the present invention is shown in FIGS.

In FIG. 3, 90 is a timer, 13 is an abnormality detection timing signal output from the timer 90 at regular intervals, and the other parts are the same blocks as in FIG.

The processing procedure is shown in the flowchart of FIG.

In this case, the normal processing for creating and editing a document is the same as that in FIG. 1, but the processing when an input device such as a keyboard becomes abnormal is different. Timer 90
Outputs an abnormality detection timing signal 13 every predetermined time, and inputs this abnormality detection timing signal 13 to an interrupt of the CPU 10. Here, the abnormality detection timing signal 13
It is possible to arbitrarily set the occurrence interval of the. When the abnormality detection timing signal 13 is input to the CPU 10, the CPU 10 inspects the keyboard 42 via the keyboard interface 41 for an abnormality by interrupt processing. As an inspection method, the CPU 10 sends a start signal to the keyboard 42, and the keyboard 42 sends a CP signal.
It is confirmed whether or not there is a response to U10 or the code that has responded is a predetermined code, and it is determined whether or not there is an abnormality by this. If there is no abnormality, interrupt processing ends,
Return to normal editing processing. In the case of an abnormality, the keyboard access is prohibited to protect the storage medium on the floppy disk drive 62 or the hard disk drive 72 and the document being edited and the format in the main memory 20. Next, the fact that the keyboard 42 is abnormal is displayed on the CRT 52, and the document and format being edited in the main memory 20 are registered as a saved document in the floppy disk drive 62 via the floppy disk drive interface 61. If the keyboard 42 is not normally recovered due to a failure or the like, the abnormality inspection of the keyboard 42 is continued, and if recovered, the interrupt processing is terminated and the normal editing processing is resumed.

According to the present invention as described above, even if an input device such as a keyboard is in an abnormal state, the registered document or the like is prevented from being destroyed, and the document being edited is saved as a saved document in a storage medium such as a floppy disk. Therefore, the document being edited is not abandoned.

[0022]

According to the present invention, even if the input device goes out of control, the document being edited and the document stored in the storage medium are prevented from being destroyed, and the document being edited is not abandoned. There is an effect on improvement and safety.
