Abstract: The device for the processing of bank notes has a modular design. It has at least one inlet (311) and at least one outlet (361,1, 361.2). The device contains a fixed part (1) and interchangeable mobile modules (31-36) each for performing a complete processing function upon the bank note-like objects to be processed. The modules (31-36) arc insertable into the fixed part (1) in such a manner, that a desired work sequence for processing the bank notes is performable. To such an extent as is possible, electric lines, components and motors (41) are mounted on the fixed part (1); the forces and/or torques required by the modules (31-36) are transmitted to the modules by means of transmission (51,1, 52.1). The modules (31-36) are pluggable into pins (2.1, 2.2, . . . ) attached to the fixed part (1), so that they are easily insertable, removable or interchangeable.
