AI Technical Summary

Technical Problem

The media handling device of Automated Teller Machines (ATMs) is prone to mechanical and electrical problems due to the accumulation of foreign objects such as dust, sand and dirt during transactions, and existing sensors are unable to detect the intrusion of small foreign objects.

Method used

It employs gate blades with hollow internal compartments, equipped with fans and pressure gauges, and forms an air shield through air inlets and vents to prevent foreign objects from entering, while monitoring air pressure changes to detect potential tampering.

Benefits of technology

It effectively prevents dust, sand and debris from entering the media processing unit, reduces maintenance needs, and can detect and respond to potential safety threats in a timely manner.

Abstract

A gate module for a media handling apparatus is provided. The module includes gate blades and a fan. Each gate blade includes a hollow internal compartment designed to contain air pumped into the compartment by the fan, and the air is exhausted through a vent in the blade when the blade is in the open position. The exhausted air creates an air shield, wherein the air is guided away from the orifice to prevent debris from entering the orifice when the blade is open. When the blade is in the closed position, it covers an orifice seal and protects the media deposit / discharge slot of the media handling apparatus from access. In an embodiment, when the blade is in the open position, the fan continuously pumps air into the compartment to exhaust the air through the vent, and when the blade is in the closed position, it keeps the compartment pressurized.
