Abstract
A sheet-thickness detector device has a sheet guide with a sheet-guide surface for guiding a sheet between a magnetic field sensor and a magnetic guide element. The magnetic field sensor, having an approach-guide plane disposed upstream in a sheet conveying direction for guiding the sheet to a detection surface, comes into direct contact with the sheet. By the structure mentioned above, the thickness of a sheet is detected so as to determine sheet double feeding and the like without producing sheet jamming.
