Abstract

PURPOSE: To detect a paper exactly by arranging a heater and a thermal sensor element to face to each other above and under the carrying-out route of the paper.
CONSTITUTION: In the upper part of a paper carrying-out route 2 to send out papers 1 one by one continuously or intermittently, a heater 3, and in the corresponding position of the heater 3 in the lower part, a thermal sensor element 4 are arranged. In this construction, the heat radiated from the heater 3 is detected by the thermal sensor element 4 after passing through the paper 1. When the detected amount of the heat is equal to the transmitting amount through one sheet of the paper 1, the thermal sensor element 4 is kept connected, and when the transmitting amount is reduced by the supply of double sheets of papers, the thermal sensor element 4 is disconnected to detect the double supply of papers. Thus, the double paper supply can be detected without being influenced by stains on the surface of the paper.
