Abstract
An identification device and method which includes adding an identification pattern to an identification object. The pattern is formed by the absence or presence of identification holes located at a plurality of points on the identification object. In addition, the holes are spaced from one another at a specified pitch. Next, the identification object is transferred along a transfer path parallel to the identification pattern. Then light or an ultrasonic wave is transmitted from one side of the transfer path in a transverse direction of the transfer path. Identification of the identification pattern of the identification object is determined on whether or not the light or the ultrasonic wave is received on the other side of the transfer path.
