Patent ID: 7090131

Claim:
A document reading processing system having a document reading apparatus for reading a slip on which magnetic ink characters are printed, the document reading apparatus being connected via a network to a host device for operating the document reading apparatus, wherein: the document reading apparatus comprises a transportation unit that conveys the slip through a transportation path; a magnetic reading unit that magnetically reads the printed magnetic ink characters from the slip in the transportation path and outputs magnetic ink character recognition (MICR) data; an optical reading unit that optically reads an image of the slip in the transportation path and outputs image data; and a control unit that controls the transportation unit, the magnetic reading unit, and the optical reading unit, according to a command from the host device; and the host device comprises a command unit that instructs the document reading apparatus to magnetically read magnetic ink characters and optically read an image from a specific slip during a single pass of the slip through the transportation path, and to transmit a read result to the host device; and a read data storage unit that stores MICR and image data transmitted from the document reading apparatus correlated to the specific slip that was read; and the control unit of the document reading apparatus interprets control commands received from the host device and controls operation according to the interpreted commands; and the command unit of the host device sends as control commands to the document reading apparatus a single-pass multiple-reading command instructing execution of both magnetic reading and optical reading in a single pass of the slip through the transportation path, a magnetically read data transmission command instructing transmission of the MICR data to the host, and an image data transmission command instructing transmission of the image data to the host; and wherein the command unit of the host device adds to the single-pass multiple-reading command a parameter for selectively specifying magnetic reading or optical reading as the type of reading of the slip during the single pass through the transportation path; and the control unit of the document reading apparatus selectively executes only the type of reading specified by the parameter in the single-pass multiple-reading command.
