The present invention provices a counter comprising: a first member disposedin at least a partial helical turn abouta longitudinal axis of an entity whose movements and/or contents are to becounted, said first member having an indicium or indiciaindicative of a count； a second member extending generally in the direction ofsaid longitudinal axis, said second member beingoperatively disposed in overlapping relationship under and over one or moreportions of said at least partial helical turn of saidfirst member； and means to effect relative movement between said first andsecond members, said movement comprising a relativeincremental rotation about said longitudinal axis.
