Title: Detecting method for duplicate feed of cut sheet and mixing of different-type sheet
Inventor: TERAMOTO NOBUO
IPC: G01N21/89
Filed: 1986-04-23
Abstract: PURPOSE:To detect the duplicate feed or the mixing of a differenttype sheet by allowing sheets to pass a detecting optical system in sequence, determining the average value of permeated light quantities at multiple sample points for each sheet, and checking whether the measured value of the inserted sheet is different from the average value. CONSTITUTION:No specific reference value is set, average values of permeated light quantities at multiple sample points for each sheet are averaged in sequence, this average value is compared with the average value at sample points for the next sheet, and if this difference is outside the predetermined range, the duplicate feed or the mixing of a different-type sheet is judged. When the permeated light quantity is remarkably increased or decreased due to the breakage, contamination, etc. of the sheet, it gives a large impact to the average value of permeated light quantities, thus this sample value is discarded.
