PURPOSE: A remote controller device for preventing loss is provided to easily search a lost article by generating a melody or origination sound in a receiving unit attached to a corresponding object or hung on the corresponding object by a ring when a user selects a switch of a specific number of a transmitting unit. CONSTITUTION: One transmitting unit has a plurality of switches(10-14) selected by a user, and a microcomputer(15) for controlling a frequency generator(17) to receive signals of the switches(10-14) and generate inter-different frequencies corresponding to the selected switches(10-14). The transmitting unit has the frequency generator(17) for selectively generating a specific frequency according to the control of the microcomputer(15), a transmission antenna(16) for transmitting the frequency generated in the frequency generator(17), and a battery(18) for supplying a power to each unit of the transmitting unit. Each of a plurality of receiving units has a reception antenna for receiving the frequency transmitted from the transmission antenna(16), and a frequency discriminator for discriminating a specific frequency among frequencies received through the reception antenna. Each of the receiving units has a microcomputer for receiving the specific frequency discriminated in the frequency discriminator, comparing the received frequency with a previously stored frequency, and outputting a melody signal and a lamp light-emitting signal when the received frequency is identical to the previously stored frequency. Each of the receiving units has a melody generator for generating a specific melody according to the control of the microcomputer, a speaker for outputting the melody generated in the melody generator, a light-emitting lamp for emitting a light according to the control of the microcomputer, and a battery for supplying an operation power to each unit of each receiving unit.
