PURPOSE:To obtain excellent transferring characteristics with neither abrasion even under usage for a long time nor fluctuation of abrasion coefficients by forming a medium transferring rubber roller of bladed urethane rubber and silicone rubber. CONSTITUTION:A medium transferring rubber roller, for instance, a pick-up roller 1 of a cash dispenser moves bills 3 to which a load 2 is applied one by one to a portion where its leading end is meshed with a feed roller 4. The bill 3 is moved between the feed roller 4 and a frictional member 5 while being slipped by the torque of the feed roller 4, and fed out from the device main through a nip roller 6. The rubber roller 1 is made of blended urethane rubber and silicone rubber. It includes the urethane rubber ranging between 30 and 95wt.%, and the silicone rubber ranging between 5 and 70wt.%. The rubber hardness is specified between 40 and 70 degrees in JIS-A. |
