Abstract: A device (2) for supporting ring binders (12) in a position where the spine (16) of the ring binder faces upwards, includes grooves (1a. 1b), in which the edge areas (15) farthest from the spine (16) provided with rings (17) of a ring binder (12) are placed. These grooves (1a. 1b) are provided with a wider width than the thickness of the ring binder cover (13, 14). The device (2) has also at least one supporting plate (8) for supporting the ring binder cover (13, 14). The groove (1a, 1b) design allows easy and quick positioning of the ring binder (12) in or removal of it from the device (2), and the ring binder (12) may be shifted sideways, when it is placed in the device (2). The supporting plate (8) ensures that it is possible to write in the ring binder (12) when it is placed in the device (2) irrespective of the degree of stiffness of the ring binder cover (13, 14). At the same time, the supporting plate (8) acts as a guide, so the ring binder (12) may readily be positioned in the grooves (1a, 1b).
