Patent ID: 8573480

Claim:
Apparatus comprising: an automated banking machine that operates responsive at least in part to data read from data bearing records to cause financial transfers, including: a card reader operative to read card data from user cards, wherein the card data corresponds to financial accounts; at least one processor associated with the machine, wherein the at least one processor is in operative connection with the card reader, wherein the at least one processor is operative to cause: a computer determination to be made that card data read from a card corresponds to a financial account concerning which financial transfers are authorized to be conducted through machine operation; and a financial transfer at least one of to and from the financial account responsive at least in part to the determination; a sheet path, wherein the sheet path is operative to receive sheets; at least one waveguide; at least one transmitter, wherein the at least one transmitter is operative to emit at least one first ultrasonic sound signal through the at least one waveguide; at least one receiver, wherein the at least one waveguide is operative to guide the at least one first ultrasonic sound signal from the at least one transmitter to a first area in the sheet path, and from the first area in the sheet path to the at least one receiver, wherein the at least one receiver is operative to output at least one first output signal responsive at least in part to a detection of the first ultrasonic sound signal in the at least one waveguide by the at least one receiver; and at least one circuit including at least one processor, in operative communication with the at least one receiver and the at least one transmitter, wherein the at least one circuit is operative to determine at least one of a sheet presence and a property of at least one sheet positioned in the first area in the sheet path responsive at least in part to the at least one first output signal from the at least one receiver.
