Abstract

A communication device comprises: a portable transmitter which comprises operation switches, an ID code storage unit, a control unit and a transmission unit; and a receiver which comprises a receiving unit, a reference code storage unit, a control unit and a control signal generating unit capable of generating a plurality of control signals, the portable transmitter transmitting an information signal containing an ID code, the receiver comparing the ID code contained in the received information signal with a reference code, and the control signal generating unit outputting a control signal when these codes coincide with each other, wherein the portable transmitter comprises ID registration mode setting means, an ID code corresponding to the operation is formed and registered in the ID code storage unit when the control unit is set to an ID registration mode and the operation switch is operated multiple times within a predetermined ID registration mode time, and a test ID code common to a plurality of portable transmitters is already registered in the ID code storage unit.

Claims

1. A communication device comprising:

a portable transmitter which comprises at least one operation switch, an ID code storage unit in which an ID code is registered, a first control unit and a transmission unit; and

a receiver which comprises a receiving unit, a reference code storage unit in which at least one reference code is registered, a second control unit and a control signal generating unit capable of generating a plurality of control signals,

wherein the portable transmitter transmits an information signal containing the ID code, the receiver compares the ID code contained in the information signal with the reference code, and the control signal generating unit supplies a control signal to a device to be controlled when the ID code and the reference code coincide with each other,

further wherein a test ID code is initially registered in the ID code storage unit of the portable transmitter, the portable transmitter comprises ID registration mode setting means, and an ID code corresponding to operation procedure of at least one operation switch is formed and registered in the ID code storage unit of the portable transmitter when the first control unit is set to an ID registration mode by the ID registration mode setting means and at least one operation switch is operated multiple times, and is formed and registered ID code super-scribes any previously registered ID code.

2. The communication device according to claim 1, wherein when the test ID code is used, only one of control signals can be supplied.

3. The communication device according to claim 1, wherein the test ID code already registered in the ID code storage unit is invalidated after the ID code is registered.

4. The communication device according to claim 1, wherein the test ID code is common to a plurality of portable transmitters and is initially registered in an ID code storage unit of each of the plurality of portable transmitters.
