Abstract

PURPOSE:To improve printing operation exceptionally by enabling the printing of the contents of a document memory means using a built-in character generator ROM regardless of a specified printing calligraphic style when a character generator ROM free to remove from a typewriter body is not connected. CONSTITUTION:When a ROM pack 10 or 11 is connected to a connector 9 as external calligraphic style, the external calligraphic style can be selected while it can not be selected when the ROM pack 10 or 11 is not connected thereto. When the ROM pack 10 or 11 is not connected to the connector 9, it is judged whether the forcible printing mode is designated. When the forcible printing mode is designated, a printer 5 performs a printing using the built-in calligraphic style, namely, the built-in ROM8 ignoring the specification of any external calligraphic style by the calligraphic style discrimination code.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to typewriters, and more particularly to electronic typewriters having a dot printer.

[Prior art] Conventionally, dots and turns are stored according to the printing font,
A character generator ROM (hereinafter referred to as ROM pack) that can be separated or connected to the main body of the device, and a dot corresponding to a printing font (hereinafter referred to as built-in font) that is different from the above-mentioned printing font (hereinafter referred to as external font). Character generator RO, which stores patterns and is built into the device
In a typewriter having an M, there are cases where an attempt is made to print a document registered in the document memory by specifying an external font. In such a case, the ROM pack specified for the external font is connected to the main body of the device and the
%, printing specified by an external font is stopped, and a request is made to connect the 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 the ROM pack of the specified external font or have lost it, you may want to print everything using the built-in font. There are cases. In these cases, operations such as specifying the printing font are 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. It is an object of the present invention to provide a typewriter with improved 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 the typewriter of the present invention, where 1 is a central processing unit (CPU) in the form of a microprocessor.
), which controls each component described below according to predetermined procedures and prints and edits documents. Reference numeral 2 denotes a read-only memory (ROM) in which is written a program for controlling each component according to a procedure predetermined by the CPU 1, for example, the procedure shown in FIG.

3 is readable/writable random access memory (RAM)
It temporarily stores data obtained as a result of calculations by the CPU 1 or data input from the keyboard 4. The keyboard 4 has various function keys for instructing various functions such as character/symbol input keys 1 for inputting document data, printing instructions, editing instructions, etc., respectively.

5 is a printer such as a dot printer, and a keyboard 4
The content inputted from the font or the document content in the document memory described later is printed based on the specified printing font. 6
is a display device such as a liquid crystal display, which displays various data entered from the keyboard 4, data obtained as a result of calculations by the CPU t based on this data, or the contents of the document memory 7. 1±, as shown in Example 2M, edited documents with a specified printing font are stored.

8 is a built-in character generator ROM (hereinafter referred to as built-in R
OM), 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. This built-in ROM 8 is placed in the main body of the device in advance and cannot be removed.

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

The ROM packs 10 and 11 are read-only memories for external expansion in which a printing font (external font) different from the printing font stored in the built-in ROMB is written in the form of a dot pattern, and are connected to the connector 9. When not in use, it can be removed from the connector 9 and stored alone. 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.

Also, although not shown, ROM pack 10 or 11
A means for detecting whether or not 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; on the other hand, if the ROM pack 10 or 11 is not connected, the 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) that specifies the built-in font is stored,
Next, a group of character codes (and related control codes) to be printed in the built-in font are stored, followed by a control code that instructs the external font, and then character codes and control codes to be printed in the external font. Each code is stored in the document memory 7 in the above-mentioned order, such that the group is stored, and then the built-in font designation code and character code group are stored.

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 document to be printed and pressing a print start key arranged on the keyboard 4.

When printing is started, the CPU controls the printer 5 while reading the stored contents from the document memory 7, and prints. At this time, it is assumed that documents and the like are stored in the document memory 7 as shown in FIG.

In this way, the contents stored in the document memory 7 are read out,
It is determined whether the content is a font discrimination code or not, and when a font discrimination code for printing is detected in step S1, it is then determined in step S2 whether the font discrimination code is an external font or a built-in font. Step S2
If the font is a built-in font, then in step S3, the printer 5 uses the built-in ROMB to print in the built-in font until the next font discrimination code appears.

On the other hand, if it is determined in step S2 that the font identification code is an external font, then in step S4 the ROM is
It is determined whether the back IO or 11 is connected to the connector 9. In step S4, the ROM pack l
If O or 11 is connected, step S
ROM pack 10 connected to connector 9 at 5
Alternatively, it is determined whether the 11 external fonts are the same as the font identification code, and if they are the same, step S6
Proceed to contact #51! The printer 5 prints using the ROM pack 10 or 11 attached to the container 9.

On the other hand, in step S5, the font identification code is
If the ROM pack 10 or 11 is different from the connected ROM pack 10 or 11, or if the ROM pack 10 or 11 is not connected to the connector 9 in step S4, then in step S7, it is determined whether the forced print mode is instructed or not. Determine. If it is not the forced print mode in step S7, then in step S8
A connection (or exchange) message for the OM 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 an external font in step S8, the internal font, that is, the built-in ROMB is used, ignoring the external font designation. The printer 5 then prints.

In this way, since the forced print mode is provided in the above example, even if the ROM pack 10 or 11 corresponding to the external font specified when registering the document in the document memory 7 is not connected to the connector 9, Force built-in typeface,
That is, it is possible to print using the built-in ROM 8.

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

[Effects] 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 typewriter main body and the removable character generator ROM can be used. When the typewriter 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 if the character generator ROM to be connected to the typewriter body is not available. In the event that the device is lost or lost, printing is performed anyway, so printing operations in such cases can be greatly improved.
