Title: Character reader
Inventor: MUKAI SHINJI
IPC: G06K9/34
Filed: 1990-11-29
Abstract: PURPOSE:To detect an accurate character position and to improve character reading accuracy by providing a character reader with the function that if the width of a detected character is not width of one character, the width of the relevant detected character is separated or connected based on information of the immediately preceding and following characters to detect the accurate position of character. CONSTITUTION:For example, if dust is adhered between character '3' and character '7' of a character string printed as '29375', profile data 15a in the X direction of the character string is obtained, and the Y-direction position detecting processing is applied to the profile data 15a to obtain a Y-directional position 16a. Profile processing is applied to the character string to obtain Y-directional profile data 15b, 15c, 15d, and 15e in an area for Y-directional 16a. In the character width detecting processing, each character width 16b, 16c, 16d, or 16e is detected. Further, in the character width error discriminating processing, each character width is compared with a preset character width 16a, and if a character width 16d is judged abnormal, it is corrected. Thus, an accurate character position is detected, thereby being able to improve the character reading accuracy.

Abstract: PURPOSE:To provide a floating magnetic head which can be improved in CSS resistance without impairing the security of a track section having a pertinent width size. CONSTITUTION:This magnetic head is constituted in such a way that a magnetic head core 4 which is shorter than the side face section of a slider 2 is stuck to the side face section of the slider 2, with the track section 6 of the core 4 being deviated toward the rails 11 and 12 of the slider 2, and the edge sections 9 of the rails 11 and 12 except the part 20 facing the track section 6, namely, the exposed parts of the edge sections 9 are chamfered. Since the core 4 is protruded from the slider 2, the chamfering of the edge sections 9 of the rail 11 on the core side 4 can be performed without reducing the width size of the track section 6 of the core 4. In addition, since the exposed parts of the edge sections 9 of the rails 11 and 12 are chamfered, magnetic recording media are not damaged by the edge sections 9 even when this magnetic head is used for the CSS system.
