Abstract

A palm-positioning and system-actuating mechanism properly positions a person'"'"'s palm in a palm-positioning area of an electronics module of an identification system and activates the means for storing in coded form the palm of a person or for comparing the person'"'"'s palm with the stored coded palm for positive identification.

Claims

1. A palm-positioning and system-actuating mechanism for properly positioning a person'"'"'s palm and for actuating a system for coding the palm or comparing the coded palm for purposes of identification, said mechanism comprising:

a plate having a palm-positioning area, said plate having an opening and an arcuate slot adjacent said opening in said palm-positioning area;

a thumb and forefinger-engaging member, pivot means pivotally mounting said thumb and forefinger-engaging member onto said plate adjacent said opening;

first switch-actuating means mounted onto said pivot means and having radiussed surface means thereon;

second switch-actuating means mounted onto said plate by pivot pin means and having a ring and little finger-engaging member thereon extending through said arcuate slot and radiussed surface means thereon;

switch means mounted on said plate means adjacent said radiussed surface means;

spring means mounted on said plate means between said switch means and said radiussed surface means;

said radiussed surface means engaging said spring means so that said spring means normally prevent said switch-actuating means from actuating said switch means, said pivot means and pivot pin means having play therein to enable said switch-actuating means to actuate said switch means via said radiussed surface means moving said spring means against said switch means when a person'"'"'s thumb and forefinger engage said thumb and forefinger-engaging member and the ring and little finger engage said ring and little finger-engaging member and move said switch-actuating means thereby properly positioning the person'"'"'s palm over said opening.

2. A palm-positioning and system-actuating mechanism according to claim 1 wherein said thumb and forefinger-engaging member includes roller means mounted on said pivot means.

3. A palm-positioning and system-actuating mechanism according to claim 2 wherein said thumb and forefinger-engaging member and said roller means have slanted surfaces to guide the person'"'"'s palm over said opening.

4. A palm-positioning and system-actuating mechanism according to claim 1 wherein said plate has another arcuate slot therein and a pin member extends through said other arcuate slot and is connected to said thumb and forefinger-engaging member and said first switch-actuating means.

5. A palm-positioning and system-actuating mechanism according to claim 1 wherein said ring and little finger-engaging member includes a roller member.

6. A palm-positioning and system-actuating mechanism according to claim 4 wherein said radiussed surface means on said first switch-actuating means are located adjacent said pivot means and said pin member and said spring means and switch means are located substantially at right angles relative to one another.

7. A palm-positioning and system-actuating mechanism according to claim 1 wherein said second switch-actuating means includes another arcuate slot therethrough and a pin member mounted on said plate extends through said other arcuate slot and includes washer means to secure said second switch-actuating means on said plate.

8. A palm-positioning and switch-actuating mechanism according to claim 1 wherein indicating lamps are connected to said switch means and said indicating lamps are energized upon actuating of said switch means to indicate proper positioning of the person'"'"'s palm over said opening.
