ABSTRACT OF THE DISCLOSURE A novel radio remote control apparatus with encoded signals for automatic rolling doors is provided herein. It includes, in combination, a signal transmitting device with a plurality of circuits arranged for transmitting encoded signals, and a signal receiving device having a plurality of circuit units functionally associated with the signal transmitting device. The circuit units are also mechanically coupled with an automatic rolling door for receiving the encoded signals from the signal transmitting device and for effecting the control operations of "up", "down" and "stop" movements of the automatic rolling door therewith. This provides an improved remote control device with a simplified circuit arrangement but with a very large range of encoding numbers.
