Abstract
The system includes a counter for entering the quantity of a block of currency, commonly referred to as a strap, in terms of the number of bills contained within the strap. A detection circuit detects various entry conditions and determines quality and fitness. Bills are sorted accordingly, and a total count is maintained. The entry is monitored for condition factors such as bill size, double bills, or bills too closely spaced, which provides for rejection of improper entry as well as inhibiting the operation of the input count for consistency. Verification of an input count is provided by further count detection in the area of collection. Sorting, in accordance with detection and gating of the fit and unfit bills is also provided, as well as individualized count control and display. Consistency of strap size is maintained by automatic insertion of card separators between straps in accordance with a desired strap size. A logic system activates machine control sequences in accordance with strap size data provided by tracking the input count and checking for a comparison. Separator control is provided by logic responsive to the count in the collector area, also in accordance with the…
