MEDIUM ACCUMULATION DEVICE AND MEDIUM TRANSACTION DEVICE

PROBLEM TO BE SOLVED: To orderly accumulate media.SOLUTION: A rejection storage 17 of an automatic teller machine 1 is configured such that paper money BL is held between a pressure roller 28 and an emission roller 25 of an emission part 24, and that the paper money BL is made to travel backward with its end areas RD and RE lifted up by a circular truncated cone part 32 of the emission roller 25, and emitted to the inside of a space 22. In this case, the rejection storage 17 is configured such that an upper guide 23 is roughly arranged only in a range inside circular truncated cone parts 32A and 32B of the emission rollers 25A and 25B, and that the paper money BL is made to travel almost straight backward in the space 22 while the bending strength of the paper money BL in a vertical direction is kept high without making the end areas RD and RE of the paper money BL abut to the upper guide 23. As a result, the rejection storage 17 is configured so that the paper money BL can be orderly accumulated while new paper money BL is overlapped so as to be aligned with the cumulative paper money CBL.
