A bi-directional snap-action register mechanism for an odometer-type mechanical register display. The mechanism includes at lease one register display wheel (61) and a bi-directional cam (17) mounted coaxially along a common shaft (1) with the register display wheel. The bi-directional cam (17) engages a helical groove (15) formed along the shaft to allow lateral displacement of the bi-directional cam in a direction parallel to a rotational axis of the shaft (1). A pin (i4) is biased by a spring into contact with the bi-directional cam. Rotation of the shaft causes the bi-directional cam to be moved with respect to the pin. The cam abruptly rotates through a predetermined angular distance when the point of contact of the biased pin with the cam moved from a smooth portion to a step transition portion of the cam. The abrupt rotation of the cam is communicated to the register display wheel to cause a new display position to be moved into view.

One aspect provides a dose counter (1) for use with a medicament dispenser which comprises a ratchet (50); a first count wheel (20) arranged to rotate about a first axis of rotation, said first count wheel including one or more ratchet drive receipt elements (24) arranged thereon for receipt of drive from said ratchet to rotate the first count wheel about said first axis of rotation; a second count wheel (30) arranged to rotate about the first axis of rotation, said second count wheel including a set of teeth (34) arranged annularly thereon; and a kick wheel (40) arranged to rotate about a second axis of rotation offset from the first axis of rotation, said kick wheel including a set of kick teeth (44) arranged annularly thereon and in meshed relationship with the teeth of the second count wheel such that rotary motion of the kick wheel results in rotary motion of the second count wheel. The first count wheel further includes at least one fixed index tooth (28a, 28b) arranged for intermittent meshing with the kick teeth of the kick wheel such that rotary motion of the kick wheel results from rotary motion of the first count wheel only when said intermittent meshing occurs.

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).
