Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a document creation/communication terminal device having a document creation/editing function and a communication function.

In recent years, in order to meet the demands of offices,
A document creation communication terminal device that is equivalent to a word processor with a document editing function with advanced communication functions, or a text processor with document editing functions and communication processing functions, such as a communication word processor, etc. A document creation terminal device capable of international communication has been developed.

A document creation/communication terminal device having such a document creation/editing function and a communication function generally includes an input section for inputting character information, format information, and control information necessary for document creation, document transmission, and system control;
a display section that displays information necessary for document creation; an output section that records created document information and received document information;
It consists of an external storage unit that stores created document information and received document information, a communication control unit that controls the transmission and reception of document information, a line connection unit that connects to a communication line, and a system control unit that controls the entire system. It is structured as follows.

Among the document production communication terminal devices configured in this way, especially those capable of international communication, the output section outputs ISO A4 size and North American size paper in portrait and landscape page formats. It is required that it can be used on mats.

However, since the horizontal page format is actually used less frequently, the output section is configured to use only the vertical page format.

In particular, when the output section is configured with a thermal printer that uses rolled recording paper, two rolls of recording paper are prepared and the recording paper is switched according to the specified page format. Since this increases the cost, only one roll of recording paper compatible with portrait page format can be used.

However, if you do this, when the landscape page format is specified, the number of characters recorded per line is greater in the landscape page format than in the portrait page format.
This results in the inconvenience that a line break occurs in the middle or the data is recorded overlappingly at the final recording position of one line, making it extremely difficult to read.

This invention has been made in view of the above points, and in the above-mentioned document creation communication terminal device, even if a page format different from the page format usable on the output unit is specified,
The purpose is to make recording easy to read.

Therefore, when the designated page format specified by the created document information or the received document information is a preset page format, the document creation communication terminal device according to the present invention is configured to set the printing pitch in advance as the printing pitch during recording. This allows you to specify a predetermined printing pitch.

Then, a
The CCU message receiving program will be explained.

FIG. 8 is a flow diagram showing the main part of the CCU message receiving program.

In the figure, a system control section 8 receives received document information data from a communication control section 5, and checks whether this data is a page format specification (PFS) code.

If the page format is specified, it is determined whether the specified page format specified by the received document information is a landscape page format, which is a predetermined specific page format.

When the specified page format is a landscape page format, the data of the received document information is output to the output unit 3, and the print pitch (character spacing) is 1/2, which is a predetermined print pitch.
Specify 15″ printing pitch.

Furthermore, if the specified page format is a portrait page format, the data is output to the output section 3, a 1/10" print pitch is specified, and the data from the communication control section 5 is specified as the page format ( (PFS) code, the data is output to the output unit 3.

In this way, the thermal printer 30 of the output section 3
When a landscape page format that cannot be used is specified, a 1/15" print pitch, which is shorter than the 1/10" print pitch when a normal portrait page format is specified, is specified to print in fine text. Record.

As a result, the printed image is printed as if it were horizontally oriented in a reduced size, making it easier to read.

In this embodiment, an example was described in which received document information is printed, but when printing document information in a file on a floppy disk in the external storage unit 4, processing similar to that of the CCU receiving program described above may be performed. This may be done using a printer output program.

Further, similar processing can also be performed by a printer control program.

Furthermore, in the above embodiment, an example was described in which only 1/10" character spacing is used as the character spacing specified by the received document information, but if a character spacing smaller than 1/10" is specified, , you can specify an even smaller character spacing. However, it is necessary that the printer has the ability to record at such character intervals.

Furthermore, when the designated page format is a specific page format, control can be performed to increase the print pitch.

For example, if a portrait page format is specified when only a landscape page format can be used, printing with a wider print pitch than the specified print pitch will make it easier to see.

As described above, according to the present invention, even if a page format different from the page format usable on the output unit is specified in the document creation communication terminal device, the document can be recorded in an easy-to-read manner.
