Title: Optical character reader
Inventor: SASAKI YOSHIMI
IPC: G06K9/32
Filed: 1979-09-10
Abstract: PURPOSE: To set the optimum reading viewfied according to the state of transportation of the reading subject and thus increase the reading efficiency for the OCR, by giving a control to the movable mirror which detects the state of transportation of the reading subject and then sets the reading viewfield.  
     CONSTITUTION: The reading subject P is transported in the direction of the arrow, and the upper end of the subject P is detected by the edge detector consisting of the light emitting substance 1a and the line sensor 1b. Based on this detection signal, the mirror control circuit varies the angle of the mirror 6 to set the optimum reading viewfield to the subject P for reading the subject P. Accordingly, the optimum reading viewfield can be set via the rotation of the mirror for the subject such as the post card having the fixed position for the postal code by detecting its upper end. As a result, the reading subject can be read with the optimum reading viewfield although the subject may be transported with a vertical shift.
