Deposit device for a stack of sheets

A device for depositing sheets in the form of a stack, comprises a housing with a deposit surface (20), arranged in the latter such that its height can be adjusted, for holding a sheet stack (78), a stacking mechanism with a roller (60) which is aligned parallel to the deposit surface (20) and can be displaced from a first end of the deposit surface (20) in the direction of the second end of the deposit surface (20), parallel to the latter and with at least one belt (70), one end of which is fixed to the housing (10) close to the first end of the deposit surface (20) and, starting from the fixing point (72), is led around the roller (60) and parallel to the deposit surface (20) to a belt storage means (36), a second roller (62) which is arranged parallel to the first roller (60) and at a radial distance from the latter, can be displaced together with the first roller (60) parallel to the deposit surface (20) and at least a second belt (74), one end of which is fixed to the housing (10) close to the second end of the deposit surface (20) and, starting from the fixing point (76), is led parallel to the deposit surface (20) and around the second roller (62) to a second belt storage means (36), guide surfaces (66, 68) for the sheets to be deposited being arranged in the roller gap (64).
