Abstract (en)
[origin: EP3509041A1] The present invention provides a sheet detection device (10) capable of detecting a variety of sheets including a variety of transparent portions. The sheet detection device (10) is configured to detect a sheet including a transparent portion (2) transmitting light in a visible range and being transported along a transport path (11), the device (10) including: at least one ultraviolet light source (20) configured to apply ultraviolet light to the transport path (11); at least one photodetector (30) configured to detect the ultraviolet light applied by the at least one ultraviolet light source (20); and a detector (40) configured to detect the sheet based on an output signal from the photodetector (30).
