Multiple device remote control transmitter

Claim 2

A remote control transmitter for selectively transmitting signals for controlling at least two different devices comprising: a housing; a first plurality of keys on said housing for activating functions common to said devices, some of said first plurality of keys being capable of activating two different control functions; a second and third plurality of keys on said housing for activating functions individual to said devices; cover means on said housing for prohibiting simultaneous access to said second and to said third plurality of keys; an integrated circuit for generating coded control signals; and means, including switch means operable by movement of said cover means, for enabling transmission of different coded control signals for activating said different devices and said different control functions by changing connections between said integrated circuit and certain of said keys.

Claim 3

The transmitter of claim 1 wherein said cover means comprise two covers mounted for slidable overlapping engagement in said housing and wherein said second and third plurality of keys are located beneath said movable covers respectively.

Claim 4

The transmitter of claim 2 wherein said first plurality of keys control functions of a television receiver, said second plurality of keys control functions of a VCR and said third plurality of keys are useful in a Text mode.

Claim 5

The transmitter of claim 3 wherein said first plurality of keys includes a group of keys, each of which controls a function in two controlled devices; said switch means operated by movement of said cover means for reconnecting said integrated circuit to produce appropriate coded control signals for said group of keys; and indicia means for identifying said functions with said keys.

Claim 6

A remote control transmitter including an integrated circuit for transmitting coded control signals for controlling functions of a TV device, a VCR device and a Text service comprising: a housing including a first plurality of keys for initiating control signals for controlling functions of said TV device, VCR device and Text service, some of said first plurality of keys being capable of activating two different control functions; second and third pluralities of keys in said housing for enabling transmission of control signals useful for activating and controlling functions of said VCR device and said Text service, respectively; a pair of slidably mounted covers on said housing for hiding said second and third plurality of keys when in a home position and for selectively exposing said second and third plurality of keys when in either of two overlapping positions; and switch means operable by said slidable covers for conditioning said integrated circuit to transmit coded control signals for activating said devices and for activating said different control functions in accordance with the position of said movable covers.

Claim 7

A remote control transmitter including an integrated circuit for transmitting coded control signals for controlling functions of a TV device, a VCR device and a Text service comprising: a housing including a first plurality of keys for initiating control signals for controlling functions of said TV device, VCR device and Text service, some of said first plurality of keys being capable of activating two different control functions; second and third pluralities of keys in said housing for enabling transmission of control signals useful for activating and controlling functions of said VCR device and said Text service, respectively; a pair of slidably mounted covers on said housing for hiding said second and third plurality of keys when in a home position and for selectively exposing said second and third plurality of keys when in either of two overlapping positions; and switch means operable by said slidable covers for conditioning said integrated circuit to transmit coded control signals for activating said devices and for activating said different control functions in accordance with the position of said movable covers.
