Abstract
An automatic finger guide for fingerprint scanners includes active scan area on the scanner surface upon which one finger rests and a non-active scan area on the scanner surface on which the other finger(s) rest to provide stability, a stop post to indicate how far forward to place the hand, a guide post to assist in positioning the finger left to right or right to left as the case may be, sensors on the post to provide feedback to the user to when the hand is properly in place and to determine the position as to where the finger comes to rest on the active scan area.
Claims7
An automatic finger positioning guide for fingerprint scanners comprising:
- a) an active scan area on the scanner surface upon which one finger rests and a non-active area on the scanner surface on which one or more of the other fingers rest to provide stability;
- b) a stop post on the scanner surface to indicate how far to place the hand longitudinally thereof, the stop post being located on the scanner surface in relation to the active scan area so as to contact the vertex defined between the side of the one finger and the side of an adjacent finger when the hand is properly in place;
- c) a guide post on the scanner surface physically separate from the stop post to assist in positioning the finger laterally, the guide post being located on the scanner surface in relation to the active scan area so as to contact a portion of the side of the finger at a location between the stop post and the finger tip when the hand is properly in place;
- and
- d) means to indicate when the hand is properly in place.

- and
- e) the stop post and the guide post being of electrically conductive material so that a circuit is completed when the hand is properly in place.
