Abstract: The present invention provides a sheet recognition device capable of collecting complete data for a recognition process without fail even when the target medium is a banknote including a transparent portion. The sheet recognition device includes: a ring memory being configured to sequentially store collection data collected by a line sensor and sequentially overwrite an oldest piece of stored collection data with a newest piece of collection data when the data volume exceeds a capacity of the ring memory; and a controller being configured to select a first data path through which the collection data collected by the line sensor is directly output to a recognition processor or a second data path through which the collection data collected by the line sensor is output to the ring memory and the stored data in the ring memory is output to the recognition processor, upon detection of arrival of a sheet by a medium detection sensor or the line sensor, the controller selecting the second data path upon detection of arrival of the sheet by the line sensor and outputting, to the recognition processor, the collection data collected by the line sensor and stored in the ring memory before the detection of arrival of the sheet.
