Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a typewriter, and more particularly to a document processing device such as an electronic typewriter having a dot printer.

[Prior Art] Conventionally, a character generator ROM (hereinafter referred to as a ROM pack) that stores dot patterns according to the printing font and can be separated or connected to the main body of the device, and the above-mentioned printing font (hereinafter referred to as an external font) have been used. A dot pattern corresponding to a printing font (hereinafter referred to as the built-in font) that is different from the external font (hereinafter referred to as the built-in font) is stored, and in a typewriter having a built-in character generator ROM, the external font is specified and registered in the document memory. You may try to print a document that has been In such a case, if the ROM pack device specified by the external font is not connected, printing specified by the external font will be stopped.
It is common to request connection of a ROM pack of the specified font.

However, in some cases, you may want to print without worrying about the font, and furthermore, if you do not have or have lost the ROM pack for the specified external font, you may want to print everything using the built-in font. There are cases. In these cases,
The operations, such as having to specify the printing font again, were complicated, resulting in extremely poor operability.

[Purpose] Therefore, in view of the above-mentioned points, an object of the present invention is to provide a mode for printing using the character generator ROM of the built-in font when the ROM pack of the external font specified at the time of document registration is not connected. An object of the present invention is to provide a document processing device that improves operability during printing.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an example of the configuration of a typewriter, which is a document processing device according to the present invention, in which 1 is a central processing unit (CPU) in the form of a microprocessor, and each configuration described below is executed in accordance with a predetermined procedure. Control elements and print and edit documents. Reference numeral 2 denotes a read-only memory (ROM) in which a program for controlling each component according to a predetermined procedure by the CPU 1, for example, the procedure shown in FIG. 3 is written.

Reference numeral 3 denotes a readable/writable random access memory (RAM), which temporarily stores data obtained as a result of calculations by the CPU 1 or data input from the keyboard 4. keyboard 4
is a character symbol input key for document data input,
Various function keys are arranged for instructing various functions such as printing instructions and editing instructions.

Reference numeral 5 denotes a printer such as a dot printer, which prints the content input from the keyboard 4 or the content of a document in a document memory, which will be described later, based on a designated printing font. 6 is a display device such as a liquid crystal display, which displays various data input from the keyboard 4;
The data obtained as a result of calculations by the CPU 1 based on this data or the contents of the document memory 7 are displayed. For example, as shown in FIG. 2, this document memory 7 stores edited documents with designated printing fonts.

8 is the built-in character generator ROM (hereinafter referred to as
This is called a built-in ROM), and the printing font (built-in font) used when printing by the printer 5 is written in the form of a dot pattern. When this built-in font is specified, the printer 5 prints using this font. do. This built-in ROM 8 is placed in the main body of the device in advance and cannot be removed.

Reference numeral 9 denotes a connector for electrically connecting ROM packs 10 and 11, which will be described later, to the main body of the apparatus.

ROM packs 10 and 11 are built-in ROM8
This is a read-only memory for external expansion in which a printing font (external font) different from the printing font stored in the memory is written in the form of a dot pattern. It can be removed from the container 9 and stored alone. this
When the ROM packs 10 and 11 are connected to the connector 9 with an external font specified, the printer 5 prints in the specified external font.

Further, although not shown, means for detecting whether or not the ROM bag 10 or 11 is connected to the connector 9 is provided, and this detection signal is supplied to the CPU 1.

Next, an overview of the operation of the typewriter of the present invention will be explained.

In the apparatus of the present invention, the selection and designation of a printing font is performed before the operator inputs from the keyboard 4 a document to be printed in that font. That is, once a printing font is selected, documents input from the keyboard 4 are printed by the printer 5 in the font before the change until the printing font is changed next time.

This also applies when an edited document with a specified font is registered in the document memory 7 and its contents are printed. In this case, if the ROM pack 10 or 11 is connected to the connector 9 as an external font, the external font can be selected;
If the ROM pack 10 or 11 is not connected, an external font cannot be selected.

FIG. 2 shows an example in which the contents of a document are registered in the document memory 7 shown in FIG. 1 so that each content of the document is printed in the order of built-in font, external font, and built-in font. In this case, first a control code (font identification code) indicating the built-in font is stored, then a group of character codes (and related control codes) to be printed in the built-in font are stored, and then an external font is stored. The instruction control code is stored, then the print code and control code group to be printed in each font are stored, and then the built-in font instruction code and the character code group are stored, and so on. Each code is stored in the document memory 7.

Next, the control process of the typewriter of the present invention will be explained in more detail with reference to the flowchart of FIG.

Printing of a document registered in the document memory 7 is started by specifying the printed book and pressing a print start key arranged on the keyboard 4.

When printing starts, CPU 1 uses document memory 7
The printer 5 is controlled while reading out the stored contents from the printer 5, and printing is performed. At this time, the document memory 7
It is assumed that documents and the like are stored in the computer as shown in FIG.

In this way, the content stored in the document memory 7 is read out, and it is determined whether the content is a font identification code or not. When the font identification code for printing is detected in step S1, the font identification code is then read out in step S2. Determine whether the code is an external font or a built-in font. If it is a built-in font in step S2, then in step S3,
Using the built-in ROM 8, the printer 5 prints in the built-in font until the next font discrimination code appears.

On the other hand, if the font identification code is determined to be an external font in step S2, then step S4
At this point, it is determined whether the ROM pack 10 or 11 is connected to the connector 9 or not. step
If the ROM pack 10 or 11 is connected in step S4, it is determined in step S5 whether or not the external font of the ROM pack 10 or 11 connected to the connector 9 is the same as the font identification code. If they are the same, step
Proceeding to S6, the printer 5 prints using the ROM pack 10 or 11 connected to the connector 9.

On the other hand, in step S5, the font identification code is different from the ROM pack 10 or 11 connected to the connector 9, or in step S4
If the ROM pack 10 or 11 is not connected to the connector 9, then in step S7 it is determined whether or not the forced character printing mode is instructed. If it is not the forced print mode in step S7, then in step S7,
A connection (or replacement) message for the ROM pack 10 or 11 is displayed on the display 6, and the printing operation of the printer 5 is temporarily interrupted.

On the other hand, when the forced printing mode is selected in step S7, even though the font discrimination code indicates the font for each part in step S9,
The printer 5 prints using the built-in font, that is, the built-in ROM 8, ignoring this external font designation.

In this way, since the forced print mode is provided in the above example, the ROM pack 10 corresponding to the external font specified when registering the document in the document memory 7
Or even if 11 is not connected to connector 9, it is forced to use the built-in font, that is, built-in ROM
8 can be used for printing.

In the above example, a specific key is not provided as a means for instructing the forced printing mode, but this specific key may be arranged on the keyboard 4 and the forced printing mode may be instructed using this specific key.

[Effect] As explained above, according to the present invention, when printing the contents of the document storage means in which a printed font is specified and an edited document is stored, the document processing device main body and the removable ROM pack can When it is not connected, the contents of the document storage means can be printed using the built-in character generator ROM regardless of the specified printing font, so you can have a ROM pack to connect to the document processing device at hand. In the event that the device is lost or lost, printing is performed anyway, so printing operations in such cases can be greatly improved.
