Abstract

PURPOSE:To reduce the memory load and to realize application of many types of fonts by reading the font data out of other terminal devices to store them as necessary when a word processing function is used by each terminal equipment. CONSTITUTION:When an operator gives an instruction via an input/output means 2, a font selection means 6 applies the polling to each of information file devices set in a network via a communication circuit L. Thus the types of fonts are read out of a font memory 5 of each information file device and then displayed on a CRT display. The font is selected by an instruction of an operator is stored in the memory 5 of its own via a communication control means 8 and a transceiver 9. Then a document is produced via a character processing part 4 by an instruction of the operator.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a network system in which a plurality of terminal devices having at least a word processing function, such as an information file device having a word processing function, are connected via communication lines. The present invention relates to a network system configured to enable the use of fonts with less memory load.

[Prior art]

In recent years, with the progress of so-called 0^ (office automation), information file devices that register and store large amounts of documents and drawings as image information, and automatic drawing devices that automatically draw blueprints, etc., have been put into practical use. In addition, network systems in which a plurality of such devices are connected as terminal devices through communication lines are becoming common in actual operation.

Furthermore, by adding a word processing function to these devices, devices that make it possible to add characters or documents to information such as image information 9 drawings are beginning to be put into practical use.

[Problem that the invention seeks to solve]

By the way, word processors create document data based on data related to characters input by operating a keyboard etc. and data related to various instructions necessary for document creation. And when outputting to a printer, etc., fonts of specific character types (for example, in the case of Japanese, Mincho, Seicho, regular PL fonts, etc., and even the same Mincho font are horizontally thick and vertically thick.

Gothic, etc.) and the number of dots in the character display (for example, 24
(24 x 32 dots, 32 x 32 dots, etc.), or one can be selected from a plurality of dots.

However, in order to be able to use a wide variety of fonts, a means that can store a corresponding amount of data is required. For example, the amount of data for a font is approximately 7 megabits if 6802 characters of the first and second level defined by JIS are stored as a set of 32 x 32 dots, or 24 x 24 dots. Dot requires approximately 3.9 megabits of storage capacity. Therefore, in order to have a configuration that allows you to select and use a wide variety of fonts, you must use a hard disk drive with a large storage capacity, or a floppy disk drive. Methods such as replacing the disk containing one type of font each time the font is used are adopted. However, in the former, a large amount of memory capacity is occupied by font data, and in the latter, the operability is not good. There is a problem.

The present invention was made in view of these circumstances, and
The purpose of the present invention is to provide a network system of terminal devices having a word processing function that makes the memory load relatively light and allows the use of many types of fonts in the entire system.

[Means for solving problems]

In the present invention, when terminal devices such as information file devices that are mutually connected in a network system have a word processing function, different types of fonts are stored in each terminal device, and each terminal device has a word processing function. The configuration is such that it is possible to read and store fonts stored in other terminal devices.

The present invention provides a network system in which a plurality of terminal devices equipped with a word processing function are connected to a communication line, in which the type of font selected before using the word processing function in each terminal device is transmitted to other terminal devices. The present invention is characterized in that each terminal device is provided with a polling means for reading out the font data from the terminal device when the font data is stored, and a storage means for storing the font read out by the polling means.

[Effect]

In the present invention, when using the word processing function on each terminal device, the font data stored in the other terminal device is read out and stored as necessary, so this font data can be used to process words. Processing functions are performed.

(Examples) Hereinafter, the present invention will be described in detail based on drawings showing examples thereof.

FIG. 3 is a schematic diagram showing the overall configuration of a network system for terminal devices according to the present invention.

In the figure, A, B, C, and D are terminal devices, and in this embodiment, specifically, they are information file devices having a word processing function. Each of these terminal devices A, B, C,
D are connected to a common communication line, forming a network system in which data can be exchanged with each other.

FIG. 1 is a block diagram showing the configuration of each of the information file devices as the terminal devices ^, B, C, and D described above.

In FIG. 1, ■ is a control means that controls the entire information file device as a terminal device, and 2 is a scanner for image input, a keyboard for character input, etc., or a CRT display for display output, This is an input/output means composed of a printer or the like for printing out.

Reference numeral 3 denotes an optical disk device as a large-capacity storage medium for storing image information and document information input from the input/output means 2, as well as composite information of the two.

Reference numeral 4 denotes a character processing section that controls the word processing function of this bti file device, and has the same functions as a standalone word processor. When the document information created by the character processing section 4 is output to the input/output means 2, font data stored in a font memory 5 constituted by, for example, a hard disk device is used.

FIG. 2 is a schematic diagram showing the structure of the storage area of this font memory 5. As shown in FIG.

The storage area of the font memory 5 is divided into a first storage area E1 and a second storage area @E2. In this embodiment, the first storage area E1 is further divided into three font areas. The first font area F1 contains the most basic and common Mincho font data common to all terminal devices A, B, C, and D. In the second and third font areas F2 and F3, for example, font data of Gothic Mincho font and Sekidai Mincho font are stored, respectively.

Similarly, basic Mincho font data is stored in the first font area F1 in the first storage area E1 of the font memory 5 of the Haku information file device. 2. Third font area F2. For example, F3 has vertical Ming font, Qing dynasty font, and Zhenlei font.

Various types of font data are stored, such as Song Dynasty font, cursive font, and Reisho 9-line font.

Note that each font area F of these first storage areas E1
l, F2. Each font data is normally stored in F3 in a non-rewritable state.

On the other hand, the second storage area E2 of the font memory 5 has a capacity capable of storing one set of font data, and the data can be freely rewritten. That is, as will be described later, this second storage area E2 includes the second storage area E1 of the first storage area El of the font memory 5 of another information file device as needed.
．． The font data stored in the third font area F2°F3 is stored.

, 6 is a font selection means for selecting a font type when the word processing function of the character processing unit 4 is used, and operates as a polling means. When the font selection means 6 receives an instruction via the input/output means 2, the font selection means 6 selects the second . Third font area F2. There are 2 [tf fonts stored in F3!
The font types of Him stored in IJ and each of the other information file devices are read via the communication line. When information on the type of font selected by the operator is input from the input/output means 2 before the character processing unit 4 starts using the word processing function, the font selection means 6 receives information to which the font belongs. It is checked in which font memory 5 of the information file device including the font memory 5 of the file device the information is stored. As a result, if it is found that the selected font is stored in the font memory 5 of another information file device, the communication control means 8 is instructed to access that information file device and transmit the font data. receive.

7 is an image processing section which processes the image information inputted by the input/output means 2 and read out from the optical disk device 3, and further synthesizes document information and image information created by the character processing section 4. etc.

Reference numeral 8 denotes the above-mentioned communication control means, which exchanges image information 1 with an information file device which is another terminal device via a communication line.
Sending/receiving document information, when receiving an instruction from the font selection means 6 as described above, accesses the selected information file device and selects the first memory of the font memory 5 of the information file device of the communication partner. The second storage area E of the font memory 5 of the information file device to which it belongs receives the transmission of the font data stored in the area E1.
2 and store it.

Note that 9 is a transceiver for actually transmitting and receiving data.

The operation of the system of the present invention configured as above will be explained below.

First, prior to using the word processing function by the character processing section 4, the operator selects which f[ font to use. This process is performed as follows. When the operator gives an instruction via the input/output means 2, the font selection means 6 polls each information file device networked via the communication line, and selects the font in the font memory 5 of each information file device. The second . Third font area F2. Reads the type of font stored in F3 and stores it in the font memory 5 of the information file device to which it belongs.
The second storage area E1 of the first storage area E1. Third font area F2
．． It is displayed on the input/output means 2, for example, a CRT display, together with the type of font stored in F3.

When the operator selects and instructs one of the font types displayed on the CRT display, the font selection means 6 determines whether the selected font is stored in the font memory 5 of the information file device to which it belongs. Find out. Note that at this time, not only the first storage area E1 but also the second storage area E2 may be checked because there is a possibility that the data has already been stored in the previous process.

As a result, if the designated font is not stored in the font memory 5 of the information-to-aisle device to which it belongs, the font selection means 6 selects the information file device that stores the designated Pi-class font data. accessed via the communication control means 8 and transceiver 9,
The information is successively extracted from the font memory 5 of the information file device and written and stored in the second storage area E2 of the font memory 5 to which it belongs.

In this way, after the font data of the selected type is written to the second storage area E2 of the font memory 5, the operator uses the word processing function of the character processing unit 4 to create a document or print it on the printer. When output is performed, the document is created or printed using the type of font initially selected by the operator.

However, if the operator does not instruct the font type, the first storage area E of the font memory 5
It is assumed that word processing is performed using the most basic Mincho font data stored in the first font area F1 of No. 1.

As for the types of font data to be stored in the first storage area E1 of the font memory 5, each terminal device (information file device in the above embodiment) stores one set of different types of font data. Or, as in the above embodiment, in addition to commonly storing the most basic type of font data, it is possible to store multiple different types of font data. The configuration is such that each device stores the font data separately, and furthermore, it does not store any font data at all, and before using the word processing function, it reads font data from another terminal device and stores it in itself before processing. Various combinations of configurations and the like are possible.

In addition, the amount of font data is generally JISC62
26, the first level is 3418 characters and the second level is 338 characters.
A total of 6802 characters (4 characters) are defined, and if each character is displayed in 32 x 32 dots, the total will be about 7 megabits, and if it is displayed in 24 x 24 dots, it will be about 3.9 megabits. .

Therefore, if the communication line has a communication capacity of, for example, 10 Mbps, one set of font data will be 32
In the case of 32 dots, the shortest time is about 0.7 seconds, 24 x 24
In the case of dots, it can be transmitted in about 0.4 seconds.

However, although actual data transmission requires several to several tens of times this time, it is a time that does not pose a problem in practice.

Further, in the above embodiment, an information file device is used as the terminal device, but it goes without saying that any device having a word processing function, including a word processor itself, may also be used, such as an automatic drawing device. be.

〔effect〕

As described above, according to the network system of the present invention,
In a terminal device having a word processing function, a large amount of font data can be used as document information with a relatively small memory load.
