ABSTRACT:
Apparatus which includes a plurality of separate weight-responsive, electronic measuring elements, such as load cells, disposed on a base insertable into the bottom of a cash drawer or the like. The drawer has a number of compartments to hold coins of different denominations, a different denomination in each compartment. The cells are disposed one per compartment and are interconnected to an electronic totalizer display unit. The cells have analog signal outputs indicative of the weight of the coins in each of the compartments. The analog signal output in each case is converted to a digital signal output and passes to a totalizer unit providing a digital display of the monetary value of the coins in each compartment, the present monetary total of all compartments, and the change just added to or removed from the drawer. The apparatus includes weighting factor units for adjusting the analog signals to reflect the differences in weight and value of the various coin denominations, for accurate totalizing. The apparatus and method are simple, inexpensive and effective to accurately total coinage amounts without requiring laborious hand counting thereof. Use of the total display comparison helps eliminate errors in making change.
