Abstract: A validator with a lighted bezel having a series of spaced lighted segments to one side of a banknote slot provides functional information and also defines an attract mode for potential purchasers. The validator is designed to enhance and to complement the traditional advertising used by the associated equipment or systems such as a vending machine. Preferably, a pulsing light sequence for turning lighted bar segments of different lengths is used.

Abstract: A banknote acceptor and dispenser uses a stacked configuration of the validator the banknote accumulator and dispenser and the banknote cassette. The banknote path is relatively short to avoid bill misalignment by providing the banknote accumulator and dispenser in the intermediary position.

Abstract: A banknote acceptor includes a validator, a removable banknote stacker and a removable non locked banknote cassette. The removable banknote stacker, when secured in the banknote acceptor, is operable by a drive member of the acceptor that remains with the acceptor when the removable banknote stacker is removed. With this arrangement, any operation problems of the removable stacker are easily overcome by replacement of the stacker. Preferably, the banknote acceptor, with the stacker removed, is able to receive and function with a locked banknote cassette having a stacker mechanism internal to the cassette.

Abstract: A banknote acceptor and dispenser uses a stacked configuration of the validator the banknote accumulator and dispenser and the banknote cassette. The banknote accumulator includes a count window providing information of the banknotes stored in the accumulator. Preferably the count window has an electronic display of the number of banknotes accumulated.

Abstract: A simple high optical efficiency reflective optical sensor for bill validator uses an inexpensive bulb having a case which is transparent to efficient luminous radiation. This case is used as a wave guide to return reflected radiation to at least one photo detector situated directly under the transparent bottom of the case. The bulb emits a narrow beam of light and is positioned in close proximity and perpendicular to a bill surface and illuminates it. The light reflected or fluoresced by the bill is collected widely with a convex lens end of the bulb case and this collected radiation is transmitted through the bulb case to the at least one photo detector. Preferably, the bulb is a light emitting diode.

Abstract: A simple method and apparatus for contactless rapid and inexpensive motion checking of flat objects, preferably of currency papers. The objects need not be identical in size, thickness, surface appearance, configuration nor deterioration. The checking is carried out by detecting of airflow oscillation under unexpected stoppage of testing object or air movement around the object especially on its front and back edges.
