A device for sorting sheet-type material, especially bank-notes, the device 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 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 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. <EOS>
