Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
171 words
A method of scanning indicia having parts of different light reflectivity, comprising the steps of: (a) directing light along a transmission path toward the indicia, and collecting light reflected off, and returning along a return path from, the indicia; (b) mounting a movable component in at least one of said paths for guiding the light therein; (c) exerting a biasing force to the component to constantly bias the component to a rest position; (d) manually moving the component away from the rest position against the biasing force to a launch position, and concomitantly storing energy; and (e) abruptly releasing the stored energy when the component is in the launch position to move the component back and forth and guide the light in said at least one path over swing distances of progressively smaller amplitude until the component returns to, and halts in, the rest position, at least one of the swing distances extending over all parts of the indicia to read the same during the back-and-forth movement of the movable component.
Claim 2
Independent Claim
171 words
A method of scanning indicia having parts of different light reflectivity, comprising the steps of: (a) directing light along a transmission path toward the indicia, and collecting light reflected off, and returning along a return path from, the indicia; (b) mounting a movable component in at least one of said paths for guiding the light therein; (c) exerting a biasing force to the component to constantly bias the component to a rest position; (d) manually moving the component away from the rest position against the biasing force to a launch position, and concomitantly storing energy; and (e) abruptly releasing the stored energy when the component is in the launch position to move the component back and forth and guide the light in said at least one path over swing distances of progressively smaller amplitude until the component returns to, and halts in, the rest position, at least one of the swing distances extending over all parts of the indicia to read the same during the back-and-forth movement of the movable component.
Claim 3
Dependent Claim
23 words
The method according to claim 1, wherein the moving step is performed by manually actuating an actuator operatively mechanically connected to the component.
Claim 4
Dependent Claim
23 words
The method according to claim 2, wherein the manually actuating step is performed by a single exertion of mechanical power on the actuator.
Claim 5
Dependent Claim
21 words
The method according to claim 3, wherein the manually actuating step is performed by a single pull on a finger-operated actuator.
Claim 6
Dependent Claim
52 words
The method according to claim 1, wherein the mounting step is performed by mounting the component for reciprocating movement about an axis in alternate circumferential directions, and wherein the moving step is performed by moving the component about the axis to the launch position which is angularly offset from the rest position.
Claim 7
Dependent Claim
39 words
The method according to claim 5, wherein the mounting step is performed by mounting the component on an elongated torsion wire extending along the axis, and wherein the moving step is performed by twisting the wire about the axis.
Claim 8
Dependent Claim
21 words
The method according to claim 6, wherein the mounting step includes stationarily anchoring opposite ends of the wire on a frame.
Claim 9
Dependent Claim
24 words
The method according to claim 5, wherein the mounting step is performed by mounting the component on one leg of a tuning fork-shaped holder.
Claim 10
Dependent Claim
20 words
The method according to claim 1, wherein the mounting step is performed by mounting a light reflector as the component.
Claim 11
Dependent Claim
20 words
The method according to claim 1, wherein the mounting step is performed by mounting a light source as the component.
Claim 12
Dependent Claim
23 words
The method according to claim 1, wherein the mounting step is performed by mounting a generally planar light reflector in the transmission path.
Claim 13
Dependent Claim
23 words
The method according to claim 1, wherein the mounting step is performed by mounting a generally concave light reflector in the return path.
Claim 14
Dependent Claim
51 words
The method according to claim 1, wherein the moving step is performed by solely exerting mechanical power, and wherein the releasing step is performed by discontinuing the exertion of mechanical power for a time period sufficient in duration to allow the component to come to a halt in the rest position.
Claim 15
Dependent Claim
16 words
The method according to claim 1, wherein all the steps are performed in a hand-held unit.
Claim 16
Dependent Claim
42 words
The method according to claim 1, wherein the step of directing light is performed by directing a laser beam along the transmission path, and wherein the step of collecting light is performed by detecting reflected laser light returning along the return path.
