Claims

[Scope of utility model registration request]

light receiving means comprising a plurality of light receiving elements provided at both ends of the transported filter paper sheets so as to be partially shielded by the paper sheets and separated at equal intervals in a direction perpendicular to the transport direction; a light-emitting means comprising a plurality of light-emitting elements provided opposite to each of the light-receiving elements with the conveyed paper sheet in between; and an AD converter converting the output of each of the light-receiving elements into a digital signal and storing the same. A switching circuit controls the output of each of the light receiving elements to be switched and sequentially input to the AD converter, and the data stored in the memory is sequentially read out, and the intervals between the light receiving elements are subdivided. What is claimed is: 1. A paper sheet edge detection device comprising: comparison control means for detecting the edge position of the paper sheet by comparing it with a value set so as to detect the edge position of the paper sheet.
