Laser scan unit housing for an image forming device

摘要

A scan unit for an imaging device having a movable mirror and one or more light sources. A light beam generated by each light source is directed towards the movable mirror, movement of the mirror causing each light beam that is reflected by the mirror to follow a distinct scan pattern. An optical assembly is associated with each reflected light beam to form an optical path for each reflected light beam from the mirror. A housing in which the movable mirror, the one or more light sources and the optical assembly are secured has at least a portion made from electrically conductive material for shielding an interior of the housing from electromagnetic fields external to the housing. A light drive circuitry card is disposed in the interior of the housing and communicatively coupled to the one or more light sources for driving the one or more light sources.

主权项

1. A scan unit for an imaging device, comprising:
a movable mirror; one or more light sources, a light beam generated by each light source being directed towards the movable mirror such that movement of the movable mirror causes each light beam that is reflected by the movable mirror to follow a distinct scan pattern; an optical assembly associated with each reflected light beam so as to form an optical path for each reflected light beam from the movable mirror; a housing in which the movable mirror, the one or more light sources and the optical assembly are secured, at least a portion of the housing made from electrically conductive material for shielding an interior of the housing from electromagnetic fields external to the housing; and a drive circuitry card disposed in the interior of the housing and communicatively coupled to the one or more light sources for driving the one or more light sources, wherein the housing comprises a conductive mesh.
