Abstract
A cutting blade wear determination device (31) of a sheet processing device includes a cutting controller (33), a cutting trace extractor (34), and a determiner (35). The cutting controller (33), instructs formation of a cutting surface in a sheet placed on a table. The cutting trace extractor (34) acquires an image captured by imaging a portion of the back surface of a sheet where formation of a cutting surface is instructed and extracts, from the image, a cutting trace that is a line at which the formed cutting surface intersects the sheet back surface. When an assumed line that is a line at which a cutting surface assumed to be formed in the sheet by the cutting blade intersects the sheet back surface does not coincide with the extracted cutting trace, the determiner (35) determines that the cutting blade instructed to form the cutting surface is worn.
