Abstract

A remote-controlled automatic door control apparatus includes a door, a driving unit connected to the door for driving the door to open and closed positions, and a control arrangement for controlling the door operation through the driving unit and including a radio communication system having a transmitter and a receiver. A signal containing a specific code transmitted from the transmitter is received by the receiver and collated with a code set previously in the receiver, and if they have a predetermined relationship with each other, an operation command is issued to the driving unit. The transmitter is capable of being set to a specific code, and the receiver includes a memory device for storing the specific code transmitted from the transmitter. A signal switching device is further provided for actuating the collating operation for collating the stored code with the signal from the transmitter under normal conditions and for storing a signal from the transmitter in the memory device if required.
