Kind Code:
B2
Abstract:
A pair of optical sensors 512 and 518 are disposed above photopolymer plates 102 and interleaf papers 118, which are alternately stacked with one another. These optical sensors 512 and 518 basically have the same structure. However, the optical sensor 518 is disposed so as to be inclined to an optical axis of reflected light, and therefore, a detection level of the optical sensor substantially becomes low. Accordingly, although the optical sensors 512 and 518 each react to the reflected light from the photopolymer plate 102, the optical sensor 518 does not react to the reflected light from the interleaf paper 118. As a result, it is determined whether the uppermost layer of the stack is the photopolymer plate 102 or the interleaf paper 118. In a discriminating device 510 of the present invention, general purpose optical sensors adapted to react to light having such a fixed intensity or greater, are used.
