Transparent or translucent paper sheet edge position detecting device, has air blast supply unit provided in feed table for supplying air blast flow that is directed on side edge and bilaterally runs over measuring range of measuring device

摘要

The device has an optoelectric measuring device (12) detecting a position of a side edge of a paper sheet. A paper sheet is provided on a guiding unit that guides a feed table. An air blast supply unit (17) is provided in the feed table for supplying air blast flow that is directed on the side edge. The air blast flow is transverse to a conveying direction, bilaterally runs over a measuring range of the optoelectric measuring device and works during the position detection.
