Zusammenfassung:A counting device for counting mechanical inputs is disclosed. The counting device (100,200) comprises a rotatably mounted first counting wheel (120,220) arranged to rotate by a predetermined amount for every input that is to be counted and a second counting wheel (130,230) in mechanical communication with the first counting wheel (120,220), and at least in part overlapping the first counting wheel (120,220). At least one of the counting wheels (120,220) comprises a circumferential lip (129,229) which supports an indicia ring (124,224) of said counting wheel (120,220), the indicia ring (124,224) comprising a circumferential array of counting indicia on an annular surface, and the circumferential lip (129,229) having a height sufficient for a counting wheel volume to be formed that receives the other counting wheel (130,230).
