Paper-leaves discriminating apparatus and sensor mounting construction of same apparatus

摘要

The present invention relates to a discriminating apparatus (sensor mounting construction) which is capable of detecting a characteristic quantity at various points on a paper sheet in order to discriminate different sorts of sheet based on a pattern of characteristic quantity. Thus, in the discriminating apparatus, a sensor (2) is made up of a plurality of characteristic quantity detecting heads (11), and a plurality of head mounting holes (21a to 21h) are made in a frame (20) installed along a conveyance plane for the sheets (10) for mounting the plurality of characteristic quantity detecting heads (11) on the frame (20) so that the plurality of characteristic quantity detecting heads (11) face the conveyance plane, and further, each of the characteristic quantity detecting heads (11) is detachably fitted in the head mounting hole (21b, 21c, 21f, 21g), of the plurality of head mounting holes (21a to 21h), corresponding to a position at which the characteristic quantity is pronounced. Further, the apparatus is applied in discriminating between the genuine and non-genuine paper sheets, or different sorts of paper sheet (for example, paper money, securities) in automatic teller machines (ATM), vending machines or the like.
