PROBLEM TO BE SOLVED: To provide an automatic transaction device having a paper sheets input/output mechanism with which no uneasiness is applied to a client. SOLUTION: This mechanism is provided with a slide arm 10 which is extended obliquely downward because of its gravity while being arranged above a separate part composed of a feed roller 8a, a pickup roller 8b and reverse roller 8c, a subpress 13 for supporting a roller 16 on the side of upper end while being supported by a top end 10a of this slide arm 19 and held at a fixed position inclined almost parallelly with a bill stage 6, a pool guide 11 arranged between the bill stage 6 and the sub-press 13 so as to move from the bill stage 6 to the oblique upside of a dispensation route 7, a bill press 12 arranged between this pool guide 11 and the subpress 13 so as to move from the bill stage 6 to this separate part, and a shutter 3 having an almost L-shaped fold part 3a for a length in contact with the roller 16 of the subpress 13 on the side of client while covering a paper money inlet/outlet port 2 and being opened obliquely upward from the client side of the paper money inlet/outlet port 2 to the depth-wise direction.
