<P>PROBLEM TO BE SOLVED: To provide a technology for processing a mark sensing card printed in various dropout colors at high speed. <P>SOLUTION: A mark sensing card reader 10 includes: an image data acquisition part 12 for acquiring image data of a mark sensing card; a dropout color identification part 13 for identifying dropout colors from detected identification codes, by detecting the identification codes for identifying the dropout colors of the mark sensing card printed in an identification code region provided on at least one of the leading end and the trailing end of the mark sensing card from the image data acquired by the image data acquisition part 12; a mark detection part 18 for detecting the presence or absence of marks entered into the mark sensing card from a dropped-out image data on which a data of a part of the mark sensing card printed by the dropout colors identified by the dropout color identification part 13 is removed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
