Description

DETAILED DESCRIPTION OF THE INVENTION <A) Technical Field of the Invention The present invention relates to a pattern information output method, and particularly to a pattern information output method for controlling the display form of displayed characters.

(B) A large amount of information is required due to the technical background, and in order to convey it, it is necessary to create many types of materials, and the information contained therein must be frequently rewritten.

It is desirable to easily create materials and documents by memorizing all the information written in materials, correcting the memorized information, and adding all new information.

(Q. Prior art and problems) Conventionally, word processors (document creation devices) have been used to create such materials and documents.

This can be done by displaying pre-stored information on the display screen of the surface device at any time, reading out information to be added to it from the memory, or inputting it to the operator via the keyboard and displaying it. The necessary information is deleted from the display screen by the operator's key operations, the document is created, and if necessary, the document is printed using a printer.

If there is a character that you want to print in bold in this part of the print area, a high-intensity flash will be applied on the display surface to make it easier to identify. In this case, the printing position was slightly shifted and the characters were typed twice to get a bold print. However, high-intensity displays are also used for other purposes, such as error displays and passwords:
It is not always easy for the operator to distinguish whether the high-intensity display is for bold printing or for these other purposes.
There has been a desire for a pattern information output device that has a simple configuration and is capable of directly displaying bold characters on a display screen.

(2) Purpose of the Invention The present invention has been made in view of the above points, and an object thereof is to provide a pattern information output method '1 which has a simple configuration and can obtain bold printed characters through operation I.
