Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to document processing workstations such as office workstations and engineering workstations.

[Conventional technology]

Conventional office workstations, as shown in the Proceedings of the Information Processing Society of Japan's 30th National Conference [High-performance Workstation Hardware Fair].

Word processing workstations such as engineering workstations display character data by storing character shape data (hereinafter referred to as character fonts) separately for each display device and printer device. The most common configuration example is shown in FIG.

Another method is to connect a hard copy device to the display device to print out characters, and the most common example of this configuration is shown in FIG.

[Problem that the invention seeks to solve]

In Conventional Example 1 above, when a document file stored in character code is displayed on the display and its contents are output to a printer, the contents of the character font may be slightly different, or it may be in one font memory but not in the other. Because there may be a pattern that is not registered in the font memory,
There was a problem in that the content displayed on the display and the content output to the printer did not completely match.

In addition, each document requires special characters depending on its content (for example, a mathematical document has a special character such as 〇 or Σ), but in order to display this character, it is necessary to register it as a custom character in each font memory. The problem was that it took time to do so. Furthermore, there was a method that read the bit information of the display memory as it is into the private memory and sent it to the printer as bit information and printed it as is, but instead of not having to send the external character information, the bit information (Kanji 4 'OX 25 characters) was used. Since the amount of information is large because it is sent as a file (approximately 70 KB), there is a problem in that it takes time to print.

In Conventional Example 2, the display memo IJi is directly output to hard copy, so only the display character font memory is needed to register external characters, and there is no need to read out the message to the private memory, but the device itself is complicated and expensive. There were many problems such as storage, not being able to freely select the paper type, and the printer being only usable for hard copies.

[Means for solving problems]

The problem mentioned above is that the character font memory is standardized, whereas character sets prepared for various purposes (for example, Gothic) are stored in the auxiliary storage device.

(Mincho font, mathematical type, italic, etc.) are transferred at high speed so that they can be replaced, and the number of the character set to be selected and the character data to be displayed are sent to the display controller and printer controller, which are then displayed and printed accordingly. This is solved by

[Effect]

Since the display and printer retrieve the font from a common character font memory, the displayed content and the printed result match perfectly. Furthermore, since the character font memory and the auxiliary storage device storing character sets are connected by a high-speed common I10 path, the time required to change character sets is not a problem.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, the auxiliary storage device 7 stores document files storing display contents and sets of character fonts (hereinafter referred to as character sets) that can be used for various purposes, such as Gothic and Mincho fonts. When the CPUI receives a request to display a document file from the operator, it reads the corresponding document file from the auxiliary storage device ff7, and controls the display controller 31 based on the output light instructed by the operator.
, or send it to the printer controller 41.

When the display controller 31 or the printer controller 41 receives the instruction, it outputs characters to the display 33 or the printer 42 according to the contents.

Further, details of this operation will be explained using FIG. 2.

In FIG. 2, the contents of the document file consist of the number and display of the character set used by the document, and the character code to be printed. If the character code is only alphanumeric and kana characters, use ASCII.
I codes and EBCDIC codes are used, and each character requires one byte of information. If you want to display kanji, it takes two bytes to represent one character. In any case, the amount of information transferred is one to forty times smaller than transmitting the display contents in a pit pattern. Character set number is CPU
1, and if the character set number is different from the character set stored in the character font memory 5 at that time, the corresponding character set is transferred from the auxiliary storage device 7 to the character font memory 5. This information transfer is performed at high speed by the DMA co/controller 8 of the high speed common I10 bus 2. next,
The CPU 1 sends a character code to be printed to the display controller 31 or printer controller 41.

The display controller 31 or printer controller 41 that receives it takes out the character font corresponding to the character code from the character font memory 5 and outputs it to the display or printer.

In this way, the content can be printed to the printer exactly as it appears on the display, and since the output information is sent in character codes, there is little output information.Workstations are ideal for document processing because they can flexibly handle various character font sets. is realized.

Furthermore, if the character font memory 5 has sufficient space, storing a plurality of frequently used character sets will result in a configuration with even better performance.

In the figure, 31 is a display controller, 32 is a Fi display memory, 51 is a character font memory, and 71 is a character font memory.
72 is a hard copy controller, and 72 is a hard copy printer.

〔Effect of the invention〕

According to the present invention, it is possible to construct a document processing workstation that can display and print documents for various purposes in exactly the same way on both displays and printers, using character fonts most suitable for the documents, and at high speed.
