ABSTRACT:
A hand operated optical character recognition system utilizes a one dimensional array of photo-sensitive elements divided into a plurality of groups, each group having at least one photo-sensitive element and defining a unit region to be scanned on a sheet bearing at least one row of characters to be recognized. The array is vertically scanned while being horizontally moved across the sheet. The number of outputs from the unit regions occupied by a character in each vertical scan and the number of vertical scans performed for the character in one horizontal scan are counted to enable the character recognition.
