Abstract

PURPOSE: To surely detect the arrival of paper money at a line-shaped photosensor position by providing a 2nd light source almost opposedly to a line-shaped photosensor, and discriminating difference in the intensity of received light. CONSTITUTION: A weak 2nd light source 5 is provided almost opposedly to a line- shaped photosensor 6. When the front edge of a conveyed paper money 1 does not arrive at the position opposed to the line-shaped photosensor 6, weak light from the 2nd light source 5 is directly made incident on the position of the line-shaped photosensor 6 facing the 2nd light source 5 but after the front edge of the conveyed paper money 1 arrives at the position facing the line-shaped photosensor 6, reflected light from the paper money 1 irradiated with a 1st light source 4 is made incident. Before the front edge of the conveyed paper money 1 arrives at the position facing the line-shaped photosensor 6, the intensity level of received light at the position of the line-shaped photosensor 6 facing the 2nd light source 5 is much higher than the intensity level of received light after the front edge of the conveyed paper money 1 arrives at there, and the remarkable difference is generated between the both. Therefore, it can be easily and surely detected that the front edge of the paper money 1 to be discriminated arrives at the position facing the one-dimensional image sensor 6.
