Abstract

PURPOSE: To improve accuracy of recognition with a simple hard constitution, by detecting the input sequence of hand-written patterns and by comparing this detection output with the input sequency, which is previously stored in a memory means, to recognize hand-written input patterns.
CONSTITUTION: Tablet plate 13 detects the position signal of pen 14, and this position signal and the ON signal of pen 14 are given to pattern control part 15, and control part 15 decomposes the hand-written pattern into picture elements on a absis of two signals and gives them to picture element sequence 16. Picture element sequence 17 is a picture element sequence retrieved from picture element sequence file 19 where all picture elements for the recognition object pattern are recognized previously, and coincidence circuit detection circuit 18 detects coincidence between sequence 16 and sequence 17, and the detection result obtained by checking whether coincidence between them is detected or not is given to decision circuit 20. Circuit 20 outputs a trigger signal to character synthesizing circuit 21 when obtaining coincidence between them, and circuit 21 takes out respective picture elements from sequence 17 and synthesizes them and types out them on typewriter 12.
