A device (100, 100') for sorting sheet-type material, especially bank-notes, the device (100, 100') comprising: a basic module (200; 200'; 200") having an input tray (202; 202'; 202") on the front side thereof; and an extension module that can be connected with the basic module and separated from said module, having an output tray (304a-d) on the front side thereof; the basic module (200; 200'; 200") and the extension module being designed in such a way and, in operation, arranged laterally immediately adjacent to one another in such a way that the input tray (202; 202'; 202") and the output tray (304a-d) face a user sitting or standing in front of the device (100, 100') and that, in operation, the sheet-type material is transported from the input tray (202; 202'; 202") to an upper deflection section of the basic module (200; 200'; 200"), from there, with a motion having a horizontal and a vertical motion component, to a lower-lying lower deflection section of the extension module and from there to the output tray (304a-d) of the extension module or that, in operation, the sheet-type material is transported from the input tray (202; 202'; 202") to a lower deflection section of the basic module (200; 200'; 200"), from there, with a motion having a horizontal and a vertical motion component, to a higher-lying upper deflection section of the extension module and from there to the output tray (304a-d) of the extension module, characterized in that the basic module and the extension module are each formed from substantially three components that can be swivelled, in each case relative to one another, in such a way that the sheet-type material transport path running inside the basic module and the extension module can be accessed from outside. a basic module (200; 200'; 200") having an input tray (202; 202'; 202") on the front side thereof; and an extension module that can be connected with the basic module and separated from said module, having an output tray (304a-d) on the front side thereof; the basic module (200; 200'; 200") and the extension module being designed in such a way and, in operation, arranged laterally immediately adjacent to one another in such a way that the input tray (202; 202'; 202") and the output tray (304a-d) face a user sitting or standing in front of the device (100, 100') and that, in operation, the sheet-type material is transported from the input tray (202; 202'; 202") to an upper deflection section of the basic module (200; 200'; 200"), from there, with a motion having a horizontal and a vertical motion component, to a lower-lying lower deflection section of the extension module and from there to the output tray (304a-d) of the extension module or that, in operation, the sheet-type material is transported from the input tray (202; 202'; 202") to a lower deflection section of the basic module (200; 200'; 200"), from there, with a motion having a horizontal and a vertical motion component, to a higher-lying upper deflection section of the extension module and from there to the output tray (304a-d) of the extension module, characterized in that the basic module and the extension module are each formed from substantially three components that can be swivelled, in each case relative to one another, in such a way that the sheet-type material transport path running inside the basic module and the extension module can be accessed from outside.
