Abstract

PURPOSE:To instruct processing after interruption by automatically switching a picture by providing a means capable of parallel processing operation to simultaneously operate an input means and a printing means, and recovering a printing menu when the printing operation is interrupted. CONSTITUTION:When the exhaustion of ink is detected in the middle of printing and the printing operation is interrupted, for example, it is necessary to inform the operator of the exhaustion of ink and to instruct the processing after the interruption of the printing operation at the same time. Therefore, the picture display of an LCD 5 is switched to the picture of the printing menu. The operator can select the operation to be subsequently performed from this printing menu picture without performing any excess operation. Thus, when the ink is exhausted, the ink ribbon is exchanged, printing is restarted by operating the key of a keyboard KB 3 for selecting the restart on the printing menu picture, and the display of the printing menu picture disappears. Similarly, even when paper is exhausted, printing is restarted by selecting the restart key after paper is supplied, and the soft key disappears from a document preparing picture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings.

FIG. 1 shows an embodiment of the configuration of the character processing apparatus of the present invention, in which 1 is a microprocessor (CPU) for controlling the entire apparatus, 2 is a bus line,
Address bus that specifies the address of each I / O memory, which will be described later, bidirectional data bus used to transfer various data, reception of read / write interrupts for each memory, etc., which will be described later, or data set timing, etc. It is composed of a control line and the like used for transmitting the.

Further, reference numeral 3 is a keyboard (KB), and as shown in FIG. 2, alphabet keys (alphanumeric characters),
Various keys such as a kana key and an insert, delete, page break, and line feed command key are provided. A keyboard controller (KBC) 4 encodes the data input from the keyboard 3 and transmits an interrupt signal to the bus line 2.

Next, 5 is a liquid crystal display (LCD)
Therefore, alphanumeric characters, kana, kanji, etc. can be displayed. A liquid crystal display controller (LCDC) 6 displays information on the liquid crystal display 5. A refresh memory (RM) 7 stores a character pattern to be displayed on the liquid crystal display 5, and appropriately outputs the character pattern according to a display drive signal from the liquid crystal display controller 6. Reference numeral 8 is a character generator (CG) in which patterns of alphanumeric characters, hiragana, katakana, kanji and special characters are stored in advance.

Further, 9 is a read-only memory (RO
M), which stores the control procedure relating to the present invention described in detail below. 10 is a random access memory (RAM) capable of writing as well as reading,
Used for temporary storage of various data or for storing information necessary for character processing. Therefore, RA
The M10 has a document memory SM as described below, for example. That is, SM is a document memory and stores character information. INDR is a key input data register, which temporarily stores key input data. ADR is a document memory address register, and is a register for instructing a storage location in the document memory SM. PSM is a print document buffer, PADR is a print address register, SSM is a saved document memory, SADR is a saved address register, 11 is a printer controller, and 12 is a printer. Reference numeral 13 is a floppy disk controller for controlling an external storage device such as a floppy disk drive, and 14 is an external storage device such as a floppy disk drive.

In the character processing device having the above structure,
Now, suppose that a document of vertical 20 lines and horizontal 30 digits is created and this document is printed. First, when the print operation is selected, in the print routine, characters are sequentially written in a certain address of the print document buffer PSM in the RAM 10, for example, after the address indicated by the print address register PADR or from the first address of the print document buffer PSM. Read the code. Next, the character code is deciphered and it is judged whether or not the function code is, for example, line feed, break, or page break. If it is a kana, kanji, or alphanumeric code that is normally printed as a character image instead of a function code, the character image is read from the CG 8 based on the character code, and the character image is read via the printer controller 11 to the printer. Send to 12 for printing. Then, the address register is incremented by 1 to proceed to the next processing. This is repeated for many characters until the print end command comes.

In the case of a function code other than the character code, for example, at the line feed mark, no character image is read from the CG 8 and instead the printer controller 11 is used.
Send carriage return and line feed signals to. The printer controller 11 converts the signal into an actual motor drive signal and causes the printer to perform a line feed operation. In the case of a page break, the paper feed motor is continuously driven until the paper end sensor detects that there is no paper. As described above, the function code does not print a character image, but is a code that can electrically control the operation of the entire apparatus and the operation of the printer. In this way, printing is performed according to the contents of the print document buffer.
This will be described below with reference to FIGS. 3 (1) and 3 (2).

In the above-described printing operation, in the document creation other than the printing operation, for example, alphanumeric characters and control symbols sequentially input from the keyboard in step S1 are temporarily stored as a key code in the register INDR, and are determined in step S2. After that, it is converted into an internal character code in step S3 and then stored in the document buffer SM in step S4. Then, in step S5, the input characters are sequentially displayed on the screen according to the contents of the document buffer SM. When performing the above two operations at the same time,
That is, when a new input operation or the like is performed during printing, a document creation screen appears on the display, and the printer or printer is printing. It suffices if the printing operation normally ends normally during such a parallel processing operation, but if, for example, no ink is detected during printing in step S6, printing cannot be continued as it is. Then, the state is maintained until the ink is replaced. However, in order to notify the operator of the absence of the ink and to instruct the processing after the interruption of the printing operation, the screen display is changed to the print menu screen in step S7. Switch to. The operator can select an operation to be performed next from this print menu screen without performing an extra operation. In this way, when there is no ink, if the ink ribbon is replaced and the key F1 is operated to select "restart" on the print menu screen, printing is restarted in step S11, The print menu screen display disappears. Similarly, if there is no paper or paper jam, after feeding the paper or checking the paper, select the Resume key on the print menu screen to restart printing, and also from the document creation screen. The key disappeared,
The key corresponding to the soft key also returns to the function of the normal key.

Next, the operation of the character processing apparatus having the above-mentioned configuration when the control procedures of FIGS. 4 (1) and 4 (2) are stored will be described. Now, suppose that a document of vertical 20 lines and horizontal 30 columns is created and this document is printed. First, when the print operation is selected, in the print routine, characters are sequentially written in a certain address of the print document buffer PSM in the RAM 10, for example, after the address indicated by the print address register PADR or from the first address of the print document buffer PSM. Read the code. Next, the character code is deciphered to determine whether it is a function code such as line feed, break, or page break. If it is a kana or kanji or alphanumeric code that is usually printed as a character image instead of a function code, based on that character code,
The character image is read out from the CG 8 and sent to the printer 12 via the printer controller 11 for printing. Then, the address register is incremented by 1 to proceed to the next processing. This is repeated for many characters until the print end command comes.

In the case of a function code other than the character code, for example, at the line feed mark, no character image is read from the CG 8 and instead the printer controller 11 is used.
Send carriage return and line feed signals to. The printer controller 11 converts the signal into an actual motor drive signal and causes the printer to perform a line feed operation. In the case of a page break, the paper feed motor is continuously driven until the paper end sensor detects that there is no paper. As described above, the function code does not print a character image, but is a code that can electrically control the operation of the entire apparatus and the operation of the printer. In this way, printing is performed according to the contents of the print document buffer.
This will be described below with reference to FIGS. 4 (1) and 4 (2).

In the above-described printing operation, in the document creation in addition to the printing operation, for example, alphanumeric characters and control symbols sequentially input from the keyboard in step S101 are temporarily stored as a key code in the input register INDR, and in step S
After the determination in step 102, the internal character code is converted in step S103, and then stored in the document buffer SM in step S104. Then, in step S105, the input characters are sequentially displayed on the screen according to the contents of the document buffer SM. When the above two operations are performed at the same time, that is, when a new input operation or the like is performed during printing, the document creation screen appears on the display, and one side or the printer is printing. The situation. It suffices for the printing operation to end normally without any problems during such parallel processing operation.
In 06, for example, when it is detected that there is no ink in the middle of printing, it is impossible to continue printing and the state is maintained until the ink is replaced. However, the operator is notified of this lack of ink. At the same time, the screen display is switched to the print menu screen in step S107 in order to instruct the processing after the interruption of the printing operation. The operator can select an operation to be performed next from this print menu screen without performing an extra operation. In this way, when there is no ink, the ink ribbon is replaced, and if the key F1 is operated to select "restart" on the print menu screen, printing is restarted in step S111, and in step S111.
At 112, the print menu screen display disappears from the screen. Similarly, if there is no paper or paper jam, after feeding the paper or checking the paper, select the restart key on the print menu screen to restart printing, and then to the document creation screen again. It will return.

Next, the operation of the character processing apparatus having the above-mentioned configuration when the control procedures of FIGS. 5 (1) and 5 (2) are stored will be described. Suppose now that a document having 20 lines in the vertical direction and 30 columns in the horizontal direction has been created, and this document is completed and stored in the external storage device. First, when the document saving operation is selected, the document saving routine uses a method such as a certain address of the saved document buffer SSM in the RAM 10, for example, after the address indicated by the storage address register SADR or from the first address of the saved document buffer SSM. The character codes are sequentially read out and sequentially written into the medium loaded in the floppy disk drive via the floppy disk controller. Hereinafter, FIGS.
-2 will be described.

In order to create another document during execution of the above-mentioned saving process, alphanumeric characters and control symbols sequentially input from the keyboard in step S201 are temporarily stored in the input register INDR as key codes and input in step S202. The code is determined, converted into an internal character code in step S204, and stored in the document buffer SM in step S204. Along with that, the document buffer SM is displayed on the screen.
The input characters are sequentially displayed according to the contents of. When the above two operations, that is, a new input operation during saving are performed, a screen for document creation appears on the display, and one or a floppy is saving the document. It suffices if the saving operation ends normally without any trouble during such parallel processing operation. For example, due to irrecoverable scratches on the medium during saving,
If the saving is not successful, step S20
When it is judged to be interrupted in step 6, it becomes impossible to continue saving as it is, and the state is maintained until the medium is replaced. However, the operator is notified of this defective medium and at the same time the screen currently being created is displayed. In order to instruct the next operation regarding the external storage device, the screen is switched to the save menu screen in step S207. The operator can select the next operation to be performed from this save menu screen without switching the screen. In this way, if the media is defective, replace the media and select "Save Document" on the Save menu screen and select the key corresponding to the document save on the menu screen. The save menu screen disappears and the document creation screen reappears. If there is not enough free space on the media, load the media with sufficient free space, and then select Save Document from the Save menu screen to restart saving and at the same time display the Save menu screen to the Create document screen. Is switched. Similarly, in the case of creating a document while initializing the media, or in the case of an interruption accident due to a defect related to the external storage device when creating a document while copying the media, The same processing is performed.

Here, the operation related to the external storage device is referred to as "FD
Assuming "D motion", the menu related to this will be referred to as "FDD menu".

Saving, loading, formatting of FDD,
A series of operations such as initialization or copying will be collectively referred to as FDD processing.

[0025]

[Effect] As described above, when some trouble occurs in the printing operation during the parallel processing and the printing is interrupted, the operator is notified of the occurrence of the accident, and
The screen switches to the print menu to receive the next instruction, and you can select the next restart process on the spot, so you do not have to select Cancel or Resume after returning to the print menu from the document creation screen. It has the effect of reducing the load on the operator.

As described above, when some trouble occurs in the printing operation during the parallel processing and the printing is interrupted, until the trouble is removed, the document creation screen is displayed. Soft keys related to print processing will be displayed, and that state will continue for a specified period of time. Even during the document creation screen, you do not have to select Cancel or Resume after returning to the print menu from the document creation screen. , With the effect of reducing the load on the operator.

As described above, when some trouble occurs in the operation of the external storage device during the parallel processing and the operation is interrupted, the trouble is eliminated or a predetermined decision is made. The menu screen related to the operation of the external storage device is displayed instead of the document creation screen for the specified time, so you do not have to select Cancel or Resume after you return to the save or initialization menu from the document creation screen once during document creation. Also, since it automatically returns to the document creation screen after the end of the instruction, it has the effect of reducing the load on the operator.
