21. A finger guide device for a biometric fingerprint scanner, the device comprising:
-
a raised portion having a substantially circular disk shape; a channel formed into the raised portion and extending from a front side of the raised portion to a rear side thereof and having a width greater at the front side than at the rear side wherein the width gradually decreases by about 50 percent between said front side and said rear side thereof in a direction toward the rear side, said channel being delimited by opposing wall portions which extend between the front and rear sides of the raised portion and wherein the wall portion generally converge toward each other in a direction toward the rear side of the raised portion; an aperture formed through the device at the channel having a sloping surface proximate to the front side of the raised portion and descending gradually towards the aperture, wherein the channel includes a stop surface adjacent to the aperture and opposite from the sloping surface, the stop surface being configured to abut a finger placed in the aperture and further configured to allow a fingernail of the finger to extend beyond the stop surface; finger selection contours comprising the raised portion having a substantially circular disk-like shape and at least one of the aperture having an oval shape, a sloped surface at a front side of the aperture, and a stop surface at a rear side of the aperture; and finger direction contours configured to direct the finger placed in the channel toward the aperture, the finger direction contours include a width of a channel decreasing in a direction from the front side of the raised portion to the rear side and at least one of rounded edges of the channel and a curved cross-section of the channel, wherein the finger direction contours further include at least one of the aperture having an oval shape, a sloped surface disposed at a front side of the aperture, and a stop surface disposed at a rear side of the aperture.
