Medium storage and feeding device and medium processing device

摘要

A medium storage and feeding device and a medium processing device that may prevent occurrences of faults more reliably than the related art. A drum (21) is provided that winds up a banknote BL nipped by pairs of tapes (28L, 28R, 30L and 30R) together with the pairs of tapes. Torque limiters (25L, 25R, 27L and 27R) are separately provided at each of tape reels (24L, 24R, 26L and 26R). The torque limiters control torques between the tape reels and reel rotation axle shafts (22 and 23), such that tensions applied to the tapes between the tape reels (24L, 24R, 26L and 26R) and the drum (21) are constant. Thus, tensions on the tapes between the respective tape reels and the drum may be kept constant, banknote nipping stability may be improved, and occurrences of faults may be prevented more reliably than in the related art.

主权项

1. A medium storage and feeding device that stores and feeds out a medium by winding and unwinding a set of two tapes, which nip the medium, between tape reels and a drum, the medium storage and feeding device comprising:
a plurality of sets of the tapes; a plurality of sets of the tape reels that respectively wind up the plurality of sets of tapes; two reel rotation axle shafts that are rotation axles of the tape reels and that are separately provided for one tape reel and another tape reel of the respective sets; a drum that winds the medium nipped by the plurality of sets of tapes together with the plurality of sets of tapes; and torque applying units that are independently provided at each of the tape reels and that apply torques to each of the tape reels such that tensions on the tapes between the tape reels and the drum are constant, when each of the tape reels rotates in a direction of winding the tapes and in a direction of unwinding the tapes.
