ABSTRACT:
In a device for exchanging objects, in particular writing instruments, two substantially identically embodied holders (5, 5') which are open at one side are provided. These holders are movable relative to one another in a plane extending substantially at right angles to there longitudinal axes (12, 12'). The object to be exchanged is held in a receptacle (20), which in cross section has substantially the shape of a regular, convex n-gon having an uneven number of sides. At each corner of the receptacle (20), there is an element of ferromagnetic material (22, 23, 24), and there is a permanent magnet (6, 6') on the inner face, located opposite the open side, of the receiving area of each holder (5, 5'). The receptacle (20) is positionally fixed in a holder (for instance, 5') by means of the aligned position of an element (23) of ferromagnetic material and of a permanent magnet (6', for example). By means of an approach toward the other holder (5'), the receptacle (20) is rotated, so that the permanent magnet (6) of the other holder (5) enters into an aligned position with one element (24) of ferromagnetic material of the receptacle (20), while the magnetic effect between the receptacle (20) and the one holder (5') is broken (FIG. 8).
