Abstract
There is provided, in accordance with this invention, an indicator apparatus comprising a sign board which is free to rotate and has a plurality of light transparent portions each being formed in a sign shape, a display board which has display perforations, a plurality of optical fibers each of which is disposed so as to be adjacent at one end to said display perforation and at the other end to said light transparent portion of said sign board, and a driving means which makes said sign board rotate.
Claims8
An indicating apparatus comprising:
- a display case;
- a display board defining a plurality of display perforations therein, said display board being arranged in the front end portion of said display case;
- a block board defining a plurality of input perforations 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 input and output ends of said fiber are respectively opposed to one of said input perforations and one of said display perforations;
- 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 or UHF broadcasting station;
- a lighting source in the rear of said sign board for applying a light beam thereof to said optical fibers;
- a first gear wheel fixed on 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, said second gear wheel being 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 with said second gear wheel.

- 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.
