Embodiment Construction
[0084] exist figure 1 and 3 shows generally a mechanical roller counting mechanism 1 comprising a plurality of numbered rollers 2 which are rotated on a common axis of rotation 4 by a step drive not shown in the figure be driven.
[0085] Such as image 3 As shown, each number roller 2 is provided with numbers 3 distributed on the circumference, and these numbers enable an optical / visual readout of the counting mechanism 1 .
[0086] The presence of the numeral 3 or the symbol is of course not necessary for a purely electronic reading of the counting mechanism. They can be omitted in this case.
[0087] Each number roller 2 is substantially designed as a cylindrical hollow body and forms an inner space 5 which is open at one end, so that an inner peripheral surface 7 emerges from the inner space.
[0088] According to the present invention, a plurality of transponders 6 are arranged according to a certain interval. figure 2 It is arranged on the inner side of the periph...
