Patent ID: 7857114

Claim:
A first banknote discrimination apparatus adapted for discriminating banknotes transported to the first banknote discrimination apparatus individually, comprising: a body formed in a box-shape, the body including two transport units which form a banknote transportation path therebetween, and a timing sensor for detecting arrival of the banknote at the first banknote discrimination apparatus; a plurality of sensors provided along the banknote transportation path, each detachably provided to the body and adapted for detecting each banknote and being enabled to be replaceable with a dummy member corresponding to the sensor; and a control unit adapted for discriminating each banknote, based on detection information detected by each of the sensors; wherein the body further includes a fastening member for securing each of the sensors and each of the dummy members to the body, the body is constructed such that the sensors are able to be selectively replaced with the dummy member corresponding to the sensor, the dummy member having substantially the same shape as the sensor, at least on the side of the transport path and being unable to detect the banknote, the control unit includes a CPU (Central Processing Unit), a program memory provided to the CPU, and a FGPA (Field Programmable Gate Array) connected with the CPU, and the CPU rewrites a program of the FGPA to update a control algorithm corresponding to the sensor when the sensor is removed from the body to be replaced with the dummy member, or corresponding to another sensor which is newly mounted to the body when the dummy member mounted to the body is replaced with another sensor.
