This paper deals with the development of a new method of detecting the number of moving sheets without contact. For example in a cash dispenser, paper sheets are transferred one by one and counted synchronously. Thus it is necessary to detect one or a many sheets to avoid mistransfer. Hitherto, the contact measuring method for detecting the transference of sheets has been used. Our noncontact sensor utilizes the variations in frequency response of the entire acoustic system of the sensor including the moving sheets. The impedance of sheets varies with its number. Thus the number of sheets shows good correspondence with the resonant frequency and frequency response of the acoustic system. It is possible to detect the number of moving sheets during a very short time period by means of variations in the frequency response.
