Patent ID: 7803032

Claim:
A remote-control toy comprising: a controller for transmitting a control signal containing an operating instruction based on an operation by a user, the operating instruction including a device identifier; a driving device for being controlled based on the control signal, the driving device corresponding to the device identifier; and an extension unit for receiving the control signal, the extension unit comprising: a unit main body; and a signal processing device detachably connected to an external portion of the unit main body, the unit main body comprising: a signal receiver for receiving the control signal; a terminal portion for outputting the received control signal to the signal processing device, the terminal portion corresponding to the device identifier; and a processor for executing output processing based on an instruction signal that is output from the signal processing device, the signal processing device comprising: a connecting portion that is connected to the terminal portion; a processing determining unit for discriminating the contents of the operating instruction contained in the control signal that is input through the connecting portion, for determining that the control signal includes the device identifier corresponding to the terminal portion, and for determining output processing to be executed by the processor corresponding to the instruction contents; and an instruction signal output unit for producing the instruction signal including output data for making the processor execute the determined output processing, and for outputting the produced instruction signal to the connecting portion, wherein the processor executes the determined output processing based on the output data included in the instruction signal that is input through the terminal portion.
