ABSTRACT:
The present invention provides a device for recording successive changes in indicia including a support structure, a front wall portion supported by the support structure, a display opening in the front wall portion, a fulcrum horizontally disposed above the opening on the rear side of the wall portion, an annular member on the rear side of the wall portion and through which the fulcrum extends eccentrically such that the annulus, when resting under its own weight on the fulcrum, presents a portion of its circumference against the opening and constructed and arranged such that manually pushing the annulus away from its rest position results in pivoting about the fulcrum and thereafter, in returning to its rest position under its own weight, moves circumferentially with respect to the fulcrum to present an adjacent circumferential portion to the opening.
