摘要：PURPOSE:To obtain a unit which traces the contour line of a character pattern for the purpose of character recognition by storing a character pattern signal, read out by an optical character read, in a two-dimensional memory. CONSTITUTION:In two-dimensional memory 1, the two-dimensional pattern of an input character is stored with white and black areas made to correspond to binary values, ''0'' and ''1'', and when access to the address of it is attained, five binary outputs, point C(i,j) and vertically and horizontally adjacent points C, U, D, L, and R, are extracted. Memory 1 and the address interlock and a traced point is registered in two-dimensional memory 2. From the left upper corner or memory 1, horizontal raster scanning operation is performed through controller 7 and address controller 3 and when the relation among five binary signals extracted in sequence agrees with the specific condition, trace controller 4 sends trace start command signal S out to start the tracing of the contour line.
