Abstract

There is provided a remote commander, or remote control of a remotely-controlled apparatus in which transmission data of another remote commander (2) is stored in a memory of the remote commander that belongs to a main body and the thus stored transmission data is transmitted again. In this remote commander, transmission data of the other remote commander (2) is stored in a RAM (1) as user remote control data, transmission data of the remote commander that belongs to the main body is stored in a ROM (3) as original remote control data and the original remote control data and the user remote control data are selected by switching means (4). Thus, the remote commander becomes more useful.

Claims

1. A remote control in which data transmitted from another remote control are received, said data are stored as user remote control data corresponding to respective operation keys and the thus stored predetermined user remote control data can be transmitted by operating said operation keys, characterized in that said remote control comprises a ROM for storing original remote control data;

switching means for selecting and using said user remote control data or said original remote control data; and

means for transmitting original remote control data from said ROM in response to operation of a key when no user remote control data corresponding to said key is stored in said remote control.

2. A programmable remote unit for transmitting control codes to remotely control equipment, comprising:

a key matrix of operating keys;

code receiving means for receiving user control codes from another remote control;

programmable memory means for storing said user control codes from said another remote control;

transmitting means for transmitting said user control codes when corresponding ones of said operating keys are operated;

permanent memory means for storing predetermined control codes;

switch means for selectively switching between said user control codes and said predetermined control codes for transmittal by said transmitting means when said operating keys are operated; and

means for transmitting said predetermined control codes from said transmitting means when an operating key is operated for which no corresponding user control codes are present in said programmable memory means even when said switch means is switched to said user control codes.
