Description

Detailed Description of the Invention [Statement of the Invention] (Industrial Application Field) The present invention provides a registered character type suitable for use when creating a dot matrix character type according to the dot printing density of a printer, for example. Dot matrix (prior art) Conventionally, when creating external characters in a dot font, the dot matrix was, for example, 24.24 dots, 32.32 dots, 4.
Each dot matrix was created using a predetermined dot matrix configuration, such as 0.0 and 40 dots. Therefore, if the dot printing density of the printer differs, it is necessary to manually recreate the external characters by repeatedly setting dots for each character individually, which requires a great deal of time and effort.

(Problems to be Solved by the Invention) As mentioned above, in the past, when the dot printing density of a printer differs, it is necessary to manually recreate the external characters one by one each time, which requires a great deal of time and effort. It required

The present invention has been made in view of the above-mentioned circumstances, and it is possible to quickly and easily create characters from registered character type patterns such as dot matrix external characters that have already been created.
A dot matrix for registered character types from which a base dot matrix pattern can be obtained [47.7 composition of the invention] (Means and effects for solving the problem) The present invention is a dot matrix that can be used to create a dot matrix pattern that has already been created. It converts the text into a vector font, and then converts it into a dot font with the desired dot matrix configuration according to the printer's dot printing density, etc. By adopting this dot matrix conversion method for registered character types, dot setting operations are performed one character at a time. By repeating the steps above, the patterns of registered character types such as external characters are removed.Compared to conventional registered character type creation means, arbitrary dot matrices can be created more quickly and efficiently (Example). Explain.
