PURPOSE: To attain the automatic recognition of a character with a proper level for an optical character reader by controlling a filter based on the contents of the decision area of a prescribed writing tool. CONSTITUTION: A light source lamp 2 irradiates the light on an input form 7 which moves toward an arrow A at a fixed speed. A filter 4 contains a pencil filter 4a and a ball pen filter 4b and can move toward an arrow B. A position deciding circuit 10 feeds the image of a writing tool decision area 1' to a line buffer 8 in accordance with vertical and horizontal distances VC and VH on the form 7. An input part 20 feeds the image on the form 7 to the buffer 8. A writing tool deciding circuit 30 decides a pencil or a ball pen based on the contents of the area 1' among the data fed to the buffer 8. A writing tool changing a circuit 40 changes the constitution of an optical character reader to fit for the pencil or ball pen in accordance with the contents decided by the circuit 30.
