Abstract
The present invention is a sweeping or reciprocating laser scanning device. The reciprocation or sweeping motion is cam driven. As the cam rotates, a lever arm is reciprocated or oscillated between two positions, which causes the laser or beam of light to move linearly, thus creating a triangular plane of light resulting in a reciprocating linear reference across the hypotenuse of the triangular plane of light.
Claims11
A laser scanning device comprising:
- one or more motors;
- one or more cams;
- one or more lever arms;
- one or more pivots;
- and
- one or more light sources;
- wherein said one or more motors rotate said one or more cams;
- wherein said one or more lever arms are connected to said one or more pivots;
- wherein said one or more light sources are mounted onto said one or more lever arms;
- wherein said one or more light sources emit a beam of light;
- and
- wherein as said one or more cams rotate, said one or more cams alternatingly pushes then releases said one or more lever arms, such that said one or more lever arms pivot on said one or more pivots, such that said beam of light moves linearly in a back and forth motion between a released position of said one or more lever arms and a pushed position of said one or more lever arms.

A laser scanning device comprising:
- a motor;
- a cam;
- a lever arm;
- a pivot;
- a light source;
- a housing;
- a return spring;
- and
- a controller;
- wherein said motor is comprised of a shaft;
- wherein said shaft is connected to said cam, such that when said shaft rotates said cam is rotated;
- wherein said lever arm is further comprised of an impact member;
- wherein said cam is in contact with said impact member;
- wherein said lever arm is connected to said pivot;
- wherein said light source is mounted onto said lever arm;
- wherein said light source emits a beam of light;
- wherein as said one or more cams rotate, said one or more cams alternatingly pushes then releases said one or more lever arms, such that said one or more lever arms pivot on said one or more pivots, such that said beam of light moves linearly in a back and forth motion between a released position of said one or more lever arms and a pushed position of said one or more lever arms;
- wherein said return spring is attached to said lever arm and said housing;
- wherein said return spring provides a tension against said one or more cams when said one or more cams pushes said impact member, such that said lever arm returns to said released position when said cam releases said lever arm;
- wherein said controller communicates electrical signals to said motor to adjust a rotation speed of said motor;
- wherein said cam is adjustable;
- wherein adjusting said cam changes at least said pushed position;
- wherein said pivot is adjustable;
- and
- wherein adjusting said pivot changes said at least said pushed position.
