Claim 3

An indicator apparatus according to claim 1, wherein a plurality of said display perforations are divided into several groups one of which constitutes one segment of a character, and transparent sign portions for forming a character or characters which are circumferentially provided in said sign board and are arranged in a matrix so as to illuminate some of said segments.

Claim 4

An indicator apparatus according to claim 1, wherein said rotatable sign board has a series of arcuate projections formed on the periphery thereof, each pair of adjacent projections defining a recess therebetween, and a ball which resiliently abuts against the periphery of said sign board, said ball causing said sign board to click-stop as said sign board rotates.

Claim 5

An indicator apparatus according to claim 3, wherein a second case is provided to enclose said lighting source positioned behind said sign board, the top wall of said second case defining a hole encasing said ball and being fixedly provided with a spring which presses downward the top of said ball so that a portion of said ball which projects from said hole abuts the recess of said sign board.

Claim 6

An indicator apparatus according to claim 1, wherein said display case is provided on the top of said driving means, and first and second grooves are provided in the front and rear end portions of said case, said display board and said block board being respectively inserted into said first and second grooves to be fixed therein.

Claim 7

An indicator apparatus according to claim 5, wherein a shaft for rotating said sign board is provided on the lower portion of said block board.

Claim 8

An indicator apparatus according to claim 1, wherein a plurality of said display perforations are regularly arranged in said display board, and a plurality of said input perforations are also regularly arranged in said block board, said display perforations and said input perforations are regularly connected with said optical fibers therebetween, and transparent sign portions each of which is in the shape of a displayed character itself is provided in sign board.

Claim 9

An indicator apparatus comprising: a display case; a display board defining a plurality of display perforations therein, said display board being arranged in the front portion of said display case; a block board defining a plurality of input performations therein, said block board being positioned parallel to said display board in the rear end portion of said display case; a plurality of optical fibers extending between said display board and said block board, each of said fibers being so arranged that said input and output end of the fibers are respectively opposed to one of said input perforations and one of said output perforations, the area defined on said block board by the plurality of said optical fibers being less than that on said display board; a disk-like sign board rotatably provided behind said block board, said sign board selectively masking a group of said input perforations of said block board and displaying a character or characters for indicating a VHF and UHF broadcasting station; a shaft for rotating said sign board mounted on said block board at a position displaced from the center of said block board so that said one group of transparent sign portions of said sign board which form character or characters are opposed to the input ends of said optical fibers; a lighting source behind said sign board for applying a light beam therefrom to said fibers; a first gear wheel fixed to said sign board; a driving means for selecting both VHF and UHF channels having a rotatable shaft projecting from the front wall of said driving means; and a second gear wheel positioned behind the rear wall of said driving means rotatable with said rotatable shaft; said display board being positioned parallel to and near the front wall of said driving means, said sign board being arranged parallel to and near the rear wall of said driving means, and said first gear wheel engaging said second gear wheel.

Claim 10

An indicator apparatus comprising: a display case; a display board defining a plurality of display perforations therein, said display board being arranged in the front portion of said display case; a block board defining a plurality of input performations therein, said block board being positioned parallel to said display board in the rear end portion of said display case; a plurality of optical fibers extending between said display board and said block board, each of said fibers being so arranged that said input and output end of the fibers are respectively opposed to one of said input perforations and one of said output perforations, the area defined on said block board by the plurality of said optical fibers being less than that on said display board; a disk-like sign board rotatably provided behind said block board, said sign board selectively masking a group of said input perforations of said block board and displaying a character or characters for indicating a VHF and UHF broadcasting station; a shaft for rotating said sign board mounted on said block board at a position displaced from the center of said block board so that said one group of transparent sign portions of said sign board which form character or characters are opposed to the input ends of said optical fibers; a lighting source behind said sign board for applying a light beam therefrom to said fibers; a first gear wheel fixed to said sign board; a driving means for selecting both VHF and UHF channels having a rotatable shaft projecting from the front wall of said driving means; and a second gear wheel positioned behind the rear wall of said driving means rotatable with said rotatable shaft; said display board being positioned parallel to and near the front wall of said driving means, said sign board being arranged parallel to and near the rear wall of said driving means, and said first gear wheel engaging said second gear wheel.
