Abstract
Abstract A channel indicator device is disclosed in which a tuner for achieving station selection between VHF and UHF band television broadcastings is provided in association with a single channel selection shaft of the tuner, a switch for band selection is also provided in connection with the channel selection shaft, and an indicator in the type of a plural-unit indication is provided, the indicator having a numeral corresponding to a selected channel in response to the channel selection and a code corresponding to a selected one of the VHF and UHF bands. The indicator has provided with a plural-unit indication member consisting of a plurality of indication elements to form a numeral "8".

A channel indicator device comprising: A. a rotary shaft connected to a tuner and having a first plurality of angular positions corresponding to channel settings of VHF channels having single-digit numbers, a second plurality of angular positions corresponding to channel settings of VHF channels having two-digit numbers, and a third plurality of angular positions corresponding to UHF chanel settings that have been assigned single-digit numbers; B. first and second multi-segment numeric indicators; C. a rotary switch comprising:
Claim 3
Dependent Claim
255 words
a first array of contacts equal in number to the total number of said positions, 2. an arm to contact a respective one of said contacts in each of said positions, 3. a first multi-position contact to be contacted by said arm over each of said second plurality of positions, 4. a second multi-position contact to be contacted by said arm over each of said third plurality of positions, and 5 a third multi-position contact connected to one terminal of a power supply and being contacted by said arm in each of said total number of positions; and D. matrix circuit means connected to each of said first array of contacts and connected to said first indicator to connect selected segments of said first indicator to said power source by said arm and said third multi-position contact to energize the UNITS number of each of said VHF and UHF channel settings, said matrix circuit means being connected to said first multi-position contact and connected to said second indicator to connect selected segments of said second indicator to said power source by said arm and said third multi-position contact to energize the TENS number of each of said VHF channel settings having a multi-digit number, and said matrix circuit means being connected to said second multi-position contact and connected to said second indicator to connect selected segments of said second indicator to said power source to energize a symbol indicative of the angular position of said shaft as being with the range of said UHF settings.
Claim 4
Dependent Claim
255 words
a first array of contacts equal in number to the total number of said positions, 2. an arm to contact a respective one of said contacts in each of said positions, 3. a first multi-position contact to be contacted by said arm over each of said second plurality of positions, 4. a second multi-position contact to be contacted by said arm over each of said third plurality of positions, and 5 a third multi-position contact connected to one terminal of a power supply and being contacted by said arm in each of said total number of positions; and D. matrix circuit means connected to each of said first array of contacts and connected to said first indicator to connect selected segments of said first indicator to said power source by said arm and said third multi-position contact to energize the UNITS number of each of said VHF and UHF channel settings, said matrix circuit means being connected to said first multi-position contact and connected to said second indicator to connect selected segments of said second indicator to said power source by said arm and said third multi-position contact to energize the TENS number of each of said VHF channel settings having a multi-digit number, and said matrix circuit means being connected to said second multi-position contact and connected to said second indicator to connect selected segments of said second indicator to said power source to energize a symbol indicative of the angular position of said shaft as being with the range of said UHF settings.
Claim 5
Dependent Claim
73 words
The channel indicator device of claim 1 in which said arm short-circuits said first multi-position contact to said third multi-position contact and to those contacts of said first array angularly aligned with said first multi-position contact in said second plurality of positions and short-circuits said second multi-position contacts to said third multi-position contact and to those contacts of said first array aligned with said second multi-position contact in said third plurality of positions.
Claim 6
Dependent Claim
55 words
The channel indicator device of claim 1 in which said matrix circuit means comprises: A. a first matrix circuit connected to each contact of said first array and to said first indicator; and B. a second matrix circuit connected to said first and second multi-position contacts and to only selected segments of said second indicator.
