Transportation state evaluation method for a recording media processing device

A transportation state evaluation program stored on a computer readable medium, said program for a recording media processing device that reads magnetic ink characters by means of a magnetic head from a recording medium passing a magnetic ink character reading position on a transportation path, and determines the transportation state of the recording medium based on a detection signal from the magnetic head and a detection signal from a multifeed detector for detecting multifeeding of the recording medium, the program causing the recording media processing device or a computer connected to the recording media processing device to execute steps including:

• performing an insertion direction evaluation process to determine based on a detection signal from the magnetic head whether the orientation of the recording medium is correct;
• performing a multifeed detection process to determine multifeeding of the recording medium based on a detection signal from the multifeed detector;
• and
• disabling the result of the insertion direction evaluation if the multifeed detection confirms multifeeding.

A recording media processing device comprising:

• a transportation path for conveying recording media;
• a magnetic head for reading magnetic ink characters from a recording media passing a predetermined magnetic ink character reading position on the transportation path;
• a multifeed detector for detecting multifeeding of the recording media;
• and
• an insertion direction evaluation unit for performing an insertion direction evaluation that determines a result based on a detection signal from the magnetic head whether the orientation of the recording medium is correct;
• a multifeeding evaluation unit for performing a multifeed evaluation determining based on a detection signal from the multifeed detector whether the recording media are in a multifeed condition;
• and
• a control unit that disables the result of the insertion direction evaluation unit when a multifeed state is confirmed by the multifeeding evaluation unit.
