Abstract

PURPOSE:To extract an output in the form of a character read information when the characters printed on a columnar micromedium, by arraying the line sensors along the circumference direction of the print medium. CONSTITUTION:A columnar micromedium 11 on which characters are printed is turned toward X and round the axial core. At the same time, the light of a light source 13 which is reflected by a semitransparent mirror 12 is irradiated, and this reflected light is detected at a sensor part 14 through a semitransparent plate 12. The sensor parts 14 are arrayed along the circumference direction. The maximum value detecting circuit 15 detects the maximum value of the output of each part 14, and the detection information is given to a gate circuit 16. The circuit 16 extracts only an output among the parts 14 as a character read information during the next scanning and in accordance with the detection information given from the circuit 15.
