Abstract
Abstract A channel indicia display for television receivers having both UHF and VHF tuning capability includes separate movable masking elements connected to be driven by the UHF and VHF tuner control shafts respectively. First and second fiber optic bundles are provided each of which has a light input end and a light output end. The light input end of each fiber optic bundle is located adjacent to a different one of the movable masks and the output ends are integrated and terminate in a common display window. Illuminating means are provided to illuminate each of the masks. Switch means associated with the VHF tuner control shaft are adopted to energize the appropriate illuminating means depending upon whether the receiver is tuned to receive a UHF or a VHF channel. A single display for similarly appearing numerals corresponding to both the VHF and UHF channels is thus provided.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
129 words
A channel indicia display for television receivers or the like having first and second frequency band tuners and separate movable control shafts adapted to respectively condition the tuners, the display comprising first and second movable indicia carrying elements each of which is operably connected to a different one of said control shafts to be driven thereby, a display window, first light transfer means for optically connecting said first indicia carrying element with said display window and second light transfer means for optically connecting said second indicia carrying element with said display window, each of said first and said second light transfer means having an output end adjacent said display window, said output ends of said means being integrated at said display window so as to form a single display.
Claim 2
Dependent Claim
129 words
A channel indicia display for television receivers or the like having first and second frequency band tuners and separate movable control shafts adapted to respectively condition the tuners, the display comprising first and second movable indicia carrying elements each of which is operably connected to a different one of said control shafts to be driven thereby, a display window, first light transfer means for optically connecting said first indicia carrying element with said display window and second light transfer means for optically connecting said second indicia carrying element with said display window, each of said first and said second light transfer means having an output end adjacent said display window, said output ends of said means being integrated at said display window so as to form a single display.
Claim 3
Dependent Claim
67 words
The display of claim 1 further comprising first illumination means for illuminating the input end of said first light transfer means to cause said first light transfer means to optically connect said first indicia carrying element with said display window and second illumination means for illuminating the input end of said second light transfer means to optically connect said second indicia carrying element with said display window.
Claim 4
Dependent Claim
41 words
The Display of claim 2 further comprising switch means operably connected to one of said control shafts for energizing one of said first and said second illumination means in accordance with the position of the shaft to which it is connected.
Claim 5
Dependent Claim
189 words
A channel indicia display for television receivers or the like having first and second frequency band tuners and separate movable control shafts adapted to respectively condition the tuners, the display comprising first and second movable indicia carrying elements each of which is operably connected to a different one of said control shafts to be driven thereby, a display window, first and second fiber optic bundles each having a light input end and a light output end, the light input end of said first bundle being positioned proximate to said first indicia carrying element and the light output end of said first bundle being positioned adjacent said display window, the light input end of said second bundle being positioned proximate to said second indicia carrying element and said light output end of said second bundle being positioned adjacent said display window, the fibers at the output end of each bundle being arranged in a pattern, the pattern formed by the output end of one bundle being integrated at said display window with the pattern formed by the output end of the other bundle so as to form a single display.
Claim 6
Dependent Claim
189 words
A channel indicia display for television receivers or the like having first and second frequency band tuners and separate movable control shafts adapted to respectively condition the tuners, the display comprising first and second movable indicia carrying elements each of which is operably connected to a different one of said control shafts to be driven thereby, a display window, first and second fiber optic bundles each having a light input end and a light output end, the light input end of said first bundle being positioned proximate to said first indicia carrying element and the light output end of said first bundle being positioned adjacent said display window, the light input end of said second bundle being positioned proximate to said second indicia carrying element and said light output end of said second bundle being positioned adjacent said display window, the fibers at the output end of each bundle being arranged in a pattern, the pattern formed by the output end of one bundle being integrated at said display window with the pattern formed by the output end of the other bundle so as to form a single display.
Claim 7
Dependent Claim
15 words
The display of claim 4 wherein each pattern is divided into first and second subpatterns.
Claim 8
Dependent Claim
29 words
The display of claim 5 wherein the first subpatterns of each bundle are integrated with each other and said second subpatterns of each bundle are integrated with each other.
Claim 9
Dependent Claim
24 words
The display of claim 6 wherein the first and second subpatterns of one of said bundles comprises three rows of fibers intersecting three columns.
Claim 10
Dependent Claim
21 words
The display of claim 7 wherein the second subpattern of said other bundle comprises three rows of fibers intersecting three columns.
Claim 11
Dependent Claim
19 words

Claim 13
Dependent Claim
32 words
The display of claim 4 wherein the output ends of the fibers from one bundle are disposed in the spaces between adjacent corresponding output ends of the fibers in the other bundle.
Claim 14
Dependent Claim
26 words
The display of claim 4 wherein the patterns are offset by a distance which is approximately half the distance between adjacent output ends of the fibers.
Claim 15
Dependent Claim
24 words
The display of claim 5 wherein the first and second subpatterns of one of said bundles comprises three rows of fibers intersecting three columns.
Claim 16
Dependent Claim
