Optical hand scanner optical assembly

Claim 2

An optical light pen for use in the reading of an encoded record member, the combination comprising: A. a housing having a longitudinally extending opening and an apex at one end thereof; B. an annular seat member received within said opening and secured within said housing: C. a ring member securely received within said housing coaxially with and adjacent said annular seat member; D. a spherical transparent lens rotatably received within said opening at the apex and supported by said seat member; E. the apex of the housing having a curvilinear portion which engages the spherical lens to firmly hold the spherical lens against itself and against said annular seat; F. a first fiber optics bundle received within the opening of said ring member and extending longitudinally within said housing for conveying light from said housing through said lens; and G. a second fiber optics bundle received within the opening of said ring member and extending longitudinally within said housing for receiving said sensing light passing through said lens into said housing.

Claim 3

The light pen of claim 1 wherein the material of said seat is the same material as the spherical lens.

Claim 4

The light pen of claim 1 wherein said annular seat is made of aluminum oxide impregnated with polytetrafluoroethylene.

Claim 5

The light pen of claim 1 wherein said spherical lens is selected from the group consisting of sapphire and ruby and said seat is composed of polytetrafluoroethylene.

Claim 6

The light pen of claim 1 wherein said seat is made of a platable material having a nickel-phosphorus coating thereon.

Claim 7

The light pen of claim 1 wherein said annular seat is integral with said housing.

Claim 8

An optical light pen for use in the reading of an encoded record member, the combination comprising: A. a generally longitudinally extending housing having an opening at one end thereof; B. an apex member having an opening therein secured to said housing with the opening of the housing being confluent with the apex member opening; C. an annular seat member received within said opening and secured within said apex member; D. a ring member securely received within said housing coaxially with and adjacent said annular seat member; E. a spherical, transparent lens rotatably received with said apex member opening and supported by said seat member; F. the end of the apex opposite said housing having a curvilinear configuration which engages the spherical lens to firmly hold the spherical lens against said seat; G. a first fiber optics bundle received within the opening of said ring member and extending longitudinally within said housing for conveying light from said housing through said lens; and H. a second fiber optics bundle received within the opening of said ring member and extending longitudinally within said housing for receiving and sensing light passing through said lens into said housing.

Claim 9

An optical light pen for use in the reading of an encoded record member, the combination comprising: A. a generally longitudinally extending housing having an opening at one end thereof; B. an apex member having an opening therein secured to said housing with the opening of the housing being confluent with the apex member opening; C. an annular seat member received within said opening and secured within said apex member; D. a ring member securely received within said housing coaxially with and adjacent said annular seat member; E. a spherical, transparent lens rotatably received with said apex member opening and supported by said seat member; F. the end of the apex opposite said housing having a curvilinear configuration which engages the spherical lens to firmly hold the spherical lens against said seat; G. a first fiber optics bundle received within the opening of said ring member and extending longitudinally within said housing for conveying light from said housing through said lens; and H. a second fiber optics bundle received within the opening of said ring member and extending longitudinally within said housing for receiving and sensing light passing through said lens into said housing.

Claim 10

The light pen of claim 7 wherein the material of said seat is the same material as the spherical lens.

Claim 11

The light pen of claim 7 wherein said annular seat is made of aluminum oxide impregnated with polytetrafluoroethylene.

Claim 12

The light pen of claim 7 wherein said spherical lens is selected from the group consisting of sapphire and ruby and said seat is composed of polytetrafluoroethylene.

Claim 13

The light pen of claim 7 wherein said seat is made of a platable material having a nickel-phosphorus coating thereon.

Claim 14

The light pen of claim 7 wherein said annular seat is integral with said housing.
