Abstract: A medium processing apparatus comprises a casing surrounded by a partitioning wall with an opening; a reel on which tape is wound; a fold-back section provided on an opposite side of the medium processing apparatus to the reel, so as to folded back the tape pulled out from the reel; a drum in the casing to be rotatable such that a rectangular shaped medium fed in the casing is wound onto the drum together with the tape that has been folded back on itself by the fold-back section; a winding guide provided further to a drum side than the tape, the winding guide closes off an internal space of the casing from the outside and presses the tape and the medium against a peripheral face of the drum; and an opening and closing section configuring a portion of the winding guide and opening or closing off the internal space.

Abstract: Provided is a means for stably accumulating the bills to be paid out to a customer. A bill press (26) has a dog-leg shape composed of a supporting face (26a) facing bills and an inclined face (26b) inclined in a direction away from the bills above the supporting face (26a), has two sliding pins (30) lined up along a movement direction on a side face thereof, and has a sliding groove (35) at the side of the bill press (26). A bent portion (35a) is provided at one end of the sliding groove (35) on the side of an accumulating tongue piece roller (28). When the bills to be paid out to a customer are accumulated in a bill deposit/withdrawal unit (10), the bill press (26) turns so that the sliding pins (30) on the side of the accumulating tongue piece roller (28) enter the bent portion (35a), and thereby the supporting face (26a) is inclined toward the accumulating tongue piece roller (28).
