PURPOSE:To allow functioning without having effects on the accuracy of the finishing of a paper piece delivery roller, and to easily ensure working, assembly, maintenance, etc., in a device of detecting the transportation of paper pieces under a condition that two sheets are stacked in an automatic deposit machine, etc. CONSTITUTION:Following rollers 6, 6' oppositely contact with a paper piece delivery roller 5 when normality that paper pieces M do not pass through a transportation route at a time of working. When one sheet of paper piece M enters, the rollers 6, 6' part from the roller 5 only by the thickness t of the paper piece M. In this case, a magnetic sensor 11 fastened to said rollers 6, 6' by a supporting portion material 7 also moves only by t, and distance with the roller 5 parts only by X0+t, X1. When two sheet stacked paper pieces M are charged, the rollers 6, 6' part from the roller 5 only by the thickness 2t of two sheet paper pieces M, the magnetic sensor 11 parts from the roller 5 only by X0+2t, X2, and a magnetic field varies in accordance with set values, thus working this device. |
