Abstract: A money drawer of a cash register has a frame which supports a number of individual coin cups and note cups. A respective weighing device, supported on a base of the register, is provided for each cup. A positioning mechanism, for example, comprised of cam followers and cam surfaces is arranged to determine the position of the frame. The arrangement is such that on closing the money drawer, the frame is lowered to release each cup such that it is engaged with as associated weighing device whereby the weight of the cash or bills in each cup may be calculated. The weight signals may be used to determine the number of cash or bills in the cups and/or their value. A simple record of each determination may be kept so that if there are errors in the cash register at the end of a period the record can be scrutinized for irregularities. The information may also be provided to processing means for storage and/or processing.
