Abstract
A fixed driving roller shaft not actuated vertically is disposed facing a sheet-reading sensor. Low-hardness sensor-opposed rollers each having a fixed clearance with respect to the sheet-reading sensor are arranged at positions opposed thereto. Transport rollers harder than the sensor-opposed rollers are arranged at positions not opposed to the sheet-reading sensor. The opposed sections of the transport rollers are formed into the sheet-transporting and sensor-opposed roller construction that has tension rollers arranged at the positions where the tension rollers come into contact with the associated transport rollers.
Claims19
A roller assembly disposed in neighborhood of a reading sensor which detects and reads information of sheets transported, the roller comprising:
- a plurality of rollers each arranged coaxially;
- and
- a plurality of resilient rollers different in hardness from each other;
- wherein a first resilient roller of the resilient rollers is disposed at a position opposed to the reading sensor, and a second resilient roller, of the resilient rollers, harder than the first resilient roller is disposed at a position not opposed to the reading sensor.
A discrimination apparatus that discriminates a denomination, and genuineness/falseness, of the paper currency transported, the apparatus comprising:
- a magnetic sensor that detects the magnetic information contained in the paper currency;
- and
- a roller assembly provided on a shaft opposed to the magnetic sensor;
- wherein:
- said roller assembly includes a sensor-opposed roller opposed to a sensor surface of the magnetic sensor, and transport rollers disposed at a position not opposed to the sensor surface, and on both sides of the sensor-opposed roller, the transport rollers coming into contact with, and transporting, the paper currency;
- and
- a required spatial interval is provided between the sensor-opposed roller and the sensor surface.
