Abstract
Abstract A device for supporting a lamp in optimum position for directing light into the input surface of a fiber optic reader. Visual inspection for lamp incandescence is made possible by exposing a portion of the lamp envelope to view. Gasket means in the device coacting with the lamp effectively seals off the lamp lens, the reader input surface and the area in between from dust or other foreign matter. The gasket means also operates as a vibration dampener for the lamp.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
133 words
In an assembly including an optical reader and a lamp, the reader having light transmitting means therein with light input and output ends, a sleeve member releasably connected to the reader with one of its ends enclosing the input end of the light transmitting means in coaxial relation thereto, the lamp being received in the other end of the sleeve member in coaxial relation to the input end of the light transmitting means, the sleeve being formed with an aperture for visual inspection of the lamp mounted therein, and sealing means between the sleeve and lamp to prevent dirt entering the sleeve through the aperture from being deposited on the principal light emitting surface of the lamp, the sealing means being a resilient annular gasket encircling the light emitting end of the lamp.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
172 words
In a fiber optic reader and lamp assembly, the reader having a preformed fiber optic bundle therein with light input and output ends, a sleeve member threadedly engaging the reader so as to enclose the input end of the fiber optic bundle, the lamp also being threadedly engaged with the sleeve member so that its light emitting end is enclosed by the member in spaced relation to the light input end of the reader bundle, the filament of the lamp being enclosed in a substantially cylindrical glass envelope the light emitting end of which is a lens, the sleeve member having an aperture in the sidewall thereof for enabling visual determination of lamp operability, and a resilient sealing element positioned between the sleeve member and lamp end to prevent dirt entering the sleeve through the aperture from being deposited on the light emitting end of the lamp, the sealing element having an annular configuration and occupying the space between the periphery of the lens and the inside wall of the sleeve member.
