Abstract
An apparatus for monitoring the performance of a currency dispenser by detecting the displacement of a roller caused by the thickness of a record member. This displacement is measured by the movement of a graded density translucent member between the photodiode and sensor of a detector. Electronic circuitry associated with the detector indicates the presence of a record member between the rollers, and also the presence of multiple record members. The fabrication of the member allows the circuitry to detect only the displacement from the static position of the rollers, eliminating the necessity for adjustment due to wear, temperature, and other mechanical factors.
