Media escape prevention for self-service terminal

A self-service terminal (SST), comprising

• a media pocket defining an opening and a pair of spaced side guides, wherein the media pocket includes a pair of opposing side walls and each side wall attached to inner walls of the side guides that enclose the media pocket, and wherein the media pocket is adapted to receive media and dispense media, and wherein tops of the side guides are curved in convex arches;
• a shutter moveable to expose and cover the opening of the media pocket, wherein the shutter is configured to moveably cover the opening in the gap, progressing from one end of the side guides to another end, contacting the filament to cause a portion of one of a pair of filament assemblies to flex;
• and
• the pair of filament assemblies, each filament assembly comprising a snap fit structure at a bottom to snap into a base, wherein each pair of filament assemblies includes a compressed portion located adjacent to the bottom on the base, wherein the compressed is portion adapted so the base maintains a lateral position of each filament with respect to the opening, and wherein each pair of the filament assemblies includes a ramped portion on a top edge of that pair and the ramped portion is adapted to allow a shutter to gradually come into contact with the top edge, wherein the base is coupled to an outer surface and outer wall of the side guides and containing deformable filaments that extend upward from the outer surface of the side guides to the shutter and to prevent media from entering a gap between the shutter and the side guides, wherein each filament assembly is arranged in an arc arrangement along the top edge of that filament assembly that is orthogonal to the convex arches of the tops of the side guides, and wherein the arc arrangement is configured to prevent lateral movement of the media when received in the media pocket, wherein a filament cross-section surface for the filament assembly is configured to be large enough to prevent damage to the media when the media is moved through the pocket, wherein the filaments comprise seven deformable filaments.

A method comprising:

• receiving and dispensing media in a self-service terminal (SST) pocket having an opening and a media picking face extending between two media side guides, wherein the pocket includes a pair of opposing inner walls and each side wall attached to side walls that enclose the pocket, and wherein tops of the media side guides are curved in convex arches;
• and
• closing a shutter over the opening and two media side guides, wherein the shutter contacts and flexes a top portion of a set of filaments on filament assemblies that are snapped at bottoms into bases with a snap fit structure and the bases are coupled to outer walls of the side guides and extending from a top edge of the outer walls toward the opening having the shutter and at a distance to inhibit media from entering respective gaps between the tops of the media side guides and a panel of the SST, and arranging each filament assembly arranged in an arch arrangement that is orthogonal to the convex arches of the tops of the media side guides and along a top edge of that filament assembly such that the arc prevents lateral movement is prevented when media is received the SST pocket and wherein filament cross-section surfaces for the filament assemblies are large enough to prevent damage to the media when the media is moved through the pocket, wherein the set of filaments comprise seven filaments, and arranging each filament assembly with a compressed portion located adjacent to the bottom on the base, wherein the compressed portion is adapted so the base maintains a lateral position of each filament assembly with respect to the opening, and wherein each filament assembly includes a ramped portion on the top edge of that filament assembly and the ramped portion is adapted to allow the shutter to gradually come into contact with the top edge, wherein.
