Bill acceptor for a gaming machine
First Claim
Patent Images
1. A gaming machine comprising:
- a bill acceptor configured to receive bills tendered, the bill acceptor comprising a sensor configured to evaluate each received bill and to output a signal indicative of one of an acceptance and a rejection of the received bill;
an annunciator having an array of illuminating elements configured to be illuminated in first, second, and third illuminating patterns, the first illuminating pattern being different from the second illuminating pattern, the second illuminating pattern being different from the third illuminating pattern, and the first illuminating pattern being different from the third illuminating pattern; and
a controller having a first counter and a second counter, the controller configured toincrement the first counter on each occurrence of an acceptance signal,increment the second counter on each occurrence of a rejection signal,determine a bill acceptance rate based upon a ratio of a count of the first counter to a sum comprising respective counts of the first and second counters,detect a malfunction of the bill acceptor based upon the bill acceptance rate,sequentially energize the array of illuminating elements in the first, second, and third patterns repetitively to indicate that a malfunction of the bill acceptor has not been detected, andsequentially energize the array of illuminating elements in the first, second, third, and second patterns repetitively to indicate a malfunction of the bill acceptor has been detected.

Abstract
A bill acceptor for a gaming machine including a receiving zone for receiving a tendered bill. A sensing device is arranged at an input region of the receiving zone for sensing at least one characteristic of the bill. A controller is in communication with the sensing device for receiving an output signal from the sensing device. An annunciator is controlled by the controller to be activated when a bill acceptance rate of the controller drops below a predetermined threshold.

9. A method of operating a bill acceptor of a gaming machine, the gaming machine including an annunciator represented by an array of illuminating elements, the method comprising:
-
receiving a bill at the bill acceptor; sensing at least one characteristic of the received bill; generating one of an acceptance signal and a rejection signal using the at least one sensed characteristic; incrementing a respective one of an acceptance counter and a rejection counter based on the respective acceptance and rejection signals; determining a bill acceptance rate of the bill acceptor based on dividing a cumulated value of the acceptance counter by a sum comprising respective cumulated values of the acceptance and rejection counters; detecting a malfunction of the bill acceptor in response to the bill acceptance rate falling below a value automatically, repetitively, and sequentially activating a plurality of illuminating elements in first, second, and third patterns, the first illuminating pattern being different from the second illuminating pattern, the second illuminating pattern being different from the third illuminating pattern, and the first illuminating pattern being different from the third illuminating pattern in response to not detecting a malfunction of the bill acceptor; and automatically, repetitively, and sequentially activating the plurality of illuminating elements in first, second, third, and second patterns in response to detecting a malfunction of the bill acceptor. - View Dependent Claims (10)
