Filed: 1987-07-03
Abstract: PURPOSE:To improve recording speed by providing a means for detection of all white lines, each one of which is non-recording data, a counting means for counting all the continuous white lines and a control means for changing the feed value of a recording element in accordance with the numerical value of said counting means. CONSTITUTION:First a control part 2 demands a host computer 1 to transfer a single line of data, and a single line of image data is output from the computer 1. This data is stored in an image memory 3. At that time, when a black dot identification circuit 4 detects black dots in the line, the former outputs a detection signal 20 to the control part 2. However, unless the black dots are detected, said circuit returns a storage address for image data of the memory 3 to its original location and adds 1 to the count of counters 2-1 in RAM of the control part 2. This action is repeated until a single line of image data containing black dots is entered and thereby all the white lines are counted. When feeding a recording medium, this numerical value is added to the feed value of said medium to change the feed value.

Title: Character recognizing device
Inventor: TAKAHASHI TAKUMI
IPC: G06K9/32
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To detect the inclination of the area independent from the size of a partial area of a picture by collating a detected inclination pattern and an angular pattern stored in a storing means so as to calculate the result of collation. SOLUTION: A partial area extracting means 1 divides a picture on a first page into some parts at first. A straight line component candidate extracting means 2 extracts a straight line candidate coordinate point from a partial area picture extracted here. Next a straight line candidate coordinate point pattern is judged by a line segment detecting matrix. The line segment detecting matrix represents the inclination of virtual straight lines respectively combining the group of the straight line candidate coordinate points and an inclination representing the line segment detecting matrix discriminated before is selected.  As an erroneous detection is easily generated by only discriminating the pattern of one straight line candidate coordinate point, the generation probability of the pattern of a present straight line candidate coordinate point based on a past detecting result is weighted to improve detecting precision.
