Abstract

PURPOSE: To discriminate "Mincho" (vertically bold and horizontally small type) from Gothic, by outputting a scanning line in the prescribed relative direction from each black point on the character line in the pattern area, calculating each tilted character stroke width of each black line from the continuous number, and processing the local character stroke width.
CONSTITUTION: A series of memory addresses on the pattern memory are generated by the address generating circuit 41, a data is sent and received to and from the pattern memory part 2, and each tilt character stroke width is calculated by the contents of the pattern memory, which have been received. And when a signal 200 showing that a binary pattern of white and black has been stored in the memory part 2 by the circuit 41 is received, the address for executing a raster scan which goes and returns once extending over the face on the pattern against the tilt, an address designating signal 201 is provided to the memory part 2, and the contents of the designated pattern memory address are transferred to the input buffer 42 through the data input signal line 202. The logic for calculating each tilted character-string stroke width by the contents of this buffer 42 is expressed by transition of a raster scan on the pattern memory and an appearance state of black and white in the raster scan.
