Patent Images
1. 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.

Abstract
A multi-device remote control transmitter has a first plurality of keys for controlling functions of a TV, a VCR and a Text service. A pair of slidable covers is provided in the housing for movement to two overlapping positions in which different second and third pluralities of keys dedicated to VCR and Text are exposed. Movement of the covers also operates switches which change the coded signals associated with a group of keys in the first plurality of keys for controlling different devices.

5. 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.
