MEDIA APERTURE PROTECTION FOR MEDIA HANDLING DEVICES
A shutter module of a media handling device is provided. The module includes a shutter blade and a fan. The shutter blade includes a hollow interior compartment designed to house air pumped into the compartment by the fan and to expel the air out through a vent in the blade when the blade is in an open position. The expelled air creates an air shield with the air being directed away from an aperture to prevent debris from entering the aperture when the blade is opened. The blade, when a closed position, covers the aperture sealing and protecting a media deposit/dispense slot of the media handling device from access. In an embodiment, the fan is continuously pumping air into the compartment when the blade is in the open position to expel the air out the vent and when the blade is in the closed position to keel the compartment pressurized.

6 . The shutter module of claim 1 , wherein the air vent is situated on a side of the shutter blade, wherein the side is situated above an aperture for a deposit/dispense slot of a media handling device when the shutter blade is in the open position, wherein the aperture is covered when the shutter blade is in a closed position.
7 . The shutter module of claim 1 , wherein the air inlet is on a backside of the shutter blade, wherein the backside faces an aperture for a deposit/dispense slot of a media handling device when the shutter blade is in a closed position.
8 . The shutter module of claim 1 , wherein the shutter blade is adapted to replace an existing shutter blade of an existing shutter module with the fan attached to the air inlet to form the shutter module.
9 . The shutter module of claim 1 , wherein the shutter module is adapted to be inserted into a media handling device to control access to an aperture associated with a media deposit/dispense slot of a media infeed/outfeed module.
10 . The shutter module of claim 1 , wherein the shutter blade is adapted to replace an existing shutter blade of an existing shutter module with the fan attached to the air inlet to form the shutter module.
11 . A media handling device, comprising:
a media depository/recycler;
a media infeed/outfeed module that comprises a media deposit/dispense slot accessible through an aperture on an outside surface of the media handling device;
a shutter module comprising:
a fan;
a tube; and
a shutter blade comprising:
a hollow interior compartment adapted to house air;
an air vent adapted to expel air from the hollow interior compartment; and
an air inlet adapted to provide access to the hollow interior compartment;
wherein the fan and the air inlet are attached by the tube;
wherein the fan is adapted to force air into the hollow interior compartment of the shutter blade when the shutter blade is in an open position;
wherein the air vent is situated above the aperture for the media deposit/dispense slot of the media infeed/outfeed module when the shutter blade is in the open position to force air provided by the fan air away from the aperture and to present debris from entering the aperture when the shutter blade is in the open position
wherein the shutter blade covers the aperture for the media deposit/dispense slot of the media infeed/outfeed module when the shutter blade in a closed position.
12 . The media handling device of claim 11 , wherein the shutter blade further includes:
a pressure gauge; and
a pressure inlet adapted to provide access to the hollow interior compartment;
wherein the pressure gauge and the pressure inlet are attached by a second tube.
13 . The media handling device of claim 11 , wherein the media handling device is configured to monitor pressures of the hollow interior compartment against a range of threshold pressures using the pressure gauge when the shutter blade is in the closed position.
14 . The media handling device of claim 13 , wherein the media handling device is further configured to process a security action when a current pressure of the hollow interior compartment deviates from the range indicating that the media deposit/dispense slot is potentially being tampered with.
15 . The media handling device of claim 13 , wherein the media handling device is further configured to activate and deactivate the fan to establish a configured pressure within the hollow interior compartment of the shutter blade when the shutter blade is in the closed position using the pressure gauge.
16 . The media handling device of claim 11 , wherein the fan is adapted to continuous run and pump air into the hollow interior compartment when the shutter blade is in the open position and when the shutter blade is in the closed position.
17 . The media handling device of claim 11 , wherein the media handling device is a peripheral to a transaction terminal that performs currency-based transactions.
18 . The media handling device of claim 17 , wherein the transaction terminal is an automated teller machine, a self-service terminal, a point-of-sale terminal, or a kiosk.
19 . A method, comprising:
activating a fan to expel air out of a hollow interior compartment of a shutter blade in a direction that is away from an aperture associated with a deposit/dispense slot of an infeed/outfeed module associated with a media handling device during a transaction at a transaction terminal when the shutter blade is in an open position to provide access to the deposit/dispense slot through the aperture; and
monitoring air pressures from a pressure gauge attached to the hollow interior compartment of the shutter blade when the shutter blade covers the aperture and is in a closed position for potential tampering with the deposit/dispense slot.
20 . The method of claim 19 further comprising:
processing a security action on the media handling device based on the monitoring when a current pressure of the hollow interior compartment deviates from an expected range of pressures.
