Abstract:
A system for imaging a fingerprint comprising:an imaging device having a field of view that defines an interrogation region; a sliding finger guide mounted to define a slide path that crosses said interrogation region, said slide path having first and second ends, said finger guide having a finger-support region with an opening configured to expose a finger of interest to said imaging device as said finger guide traverses said slide path; and means for restricting displacement of said finger guide from said first end in an absence of an applied force in a direction generally perpendicular to said slide path, said means for restricting displacement also including a spring that biases said finger guide to provide a counterforce to said applied force in said direction generally perpendicular to said slide path, said means for restricting displacement also including a detent-and-notch arrangement in which a second spring biases said finger guide such that a plurality of detents reside within a plurality of notches to define a lock condition for said finger guide.
