A magnetic pattern recognition method and apparatus capable of preventing magnetic noise from the pulse motor from affecting MICR character recognition processing while said pulse motor transports a document printed with MICR characters. The pulse motor is driven and noise signals detected by the magnetic head from a portion of the document not containing MICR characters are captured synchronized to the drive pulse. This is repeated for plural cycles to obtain the medium of plural signals as the compensation data. The raw detection signals detected by the magnetic head from another portion of the document containing MICR characters are then captured synchronized to the drive pulse. The compensation data is then subtracted from the raw detection signals to obtain the MICR character recognition data.

Magnetic pattern recognition method and apparatus

Printing to aNd MICR code reading from a cut-sheet form imprinted with an MICR code, such as personal checks, are continuously accomplished by a single apparatus, thereby simplifying processing and reducing the required installation space. A magnetic head and a magnet for reading the MICR code are disposed on the slope of a paper path provided in a printer housing. A personal check in paper path is held by cut-sheet form loading rollers and/or transportation rollers which operate at a synchronized speed, and is passed over the magnetic head for MICR code reading. Thereafter, the personal check is held by the loading rollers and/or the transportation rollers for endorsement printing by the print head.
