Abstract
Abstract A dental camera system includes an elongated cylindrical housing having an internal cavity for supporting a miniature video camera. The housing includes an elongated notch which exposes the focusing and aperture adjustment controls of the video camera for easy manipulation. An elongated knurled focusing sleeve is coupled to the focus ring of the camera. The housing further supports a pair of fiber-optic light pipes having offset positioning with respect to the camera lens to provide an improved illumination pattern. A dental mirror is coupled to an extendable support within the housing and a multiply positioned detent mechanism permits the mirror extension from the camera lens to be adjusted. The housing terminates at the end remote from the camera lens in a pair of opposed C-shaped split caps which provide closure of the housing end and encircle the camera cable and light pipes.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
107 words
For use in imaging a portion of the mouth and teeth of a patient, a dental camera system comprising: a video camera defining an elongated generally cylindrical shape and having a frontal lens, an aperture adjustment ring, a focus adjustment ring and a connecting cable; a housing defining a generally cylindrical shape and having an interior passage configured to receive said camera such that said aperture adjustment ring and focus adjustment ring are exposed; a pair of light sources positioned in an offset array adjacent said frontal lens; a mirror support coupled to said housing and adjustably extending thereupon; and a mirror secured to said mirror support.
Claim 2
Dependent Claim
107 words
For use in imaging a portion of the mouth and teeth of a patient, a dental camera system comprising: a video camera defining an elongated generally cylindrical shape and having a frontal lens, an aperture adjustment ring, a focus adjustment ring and a connecting cable; a housing defining a generally cylindrical shape and having an interior passage configured to receive said camera such that said aperture adjustment ring and focus adjustment ring are exposed; a pair of light sources positioned in an offset array adjacent said frontal lens; a mirror support coupled to said housing and adjustably extending thereupon; and a mirror secured to said mirror support.
Claim 3
Dependent Claim
25 words
A dental camera system as set forth in claim 1 wherein said housing defines an elongated notch for exposing said focus and aperture adjustment rings.
Claim 4
Dependent Claim
21 words
A dental camera system as set forth in claim 2 further including a cylindrical sleeve received upon said focus adjustment ring.
Claim 5
Dependent Claim
40 words
A dental camera as set forth in claim 3 wherein said housing defines an interior mirror support passage beneath said camera and wherein said mirror support includes an elongated shaft extending into said mirror support passage in a slidable attachment.
Claim 6
Dependent Claim
41 words
A dental camera system as set forth in claim 4 wherein said housing includes a detent mechanism communicating with said detent passage and wherein said elongated shaft defines a plurality of spaced detent grooves for being engaged by said detent mechanism.
Claim 7
Dependent Claim
57 words
A dental camera system as set forth in claim 5 wherein said housing defines a front face and a pair of offset apertures and wherein said pair of light sources include a pair of fiber-optic light pipes having output ends within said offset apertures and extending through said housing for coupling to a remote source of light.
Claim 8
Dependent Claim
37 words
