PROBLEM TO BE SOLVED: To power, and simultaneously transmit control information to, a performance part configured to output performance such that sufficient power is supplied to the performance part.SOLUTION: A base part 1 acquires control information from a secondary toy body 100B, and performs electromagnetic induction type transmission of a signal modulated by intermittently suspending a power feeding signal on the basis of the control information. A performance part 2 comprises: a power supply circuit 23 that receives a signal transmitted from the base part 1 and generates a power supply voltage on the basis of the received signal; a demodulation circuit 24 that extracts the control information from the received signal; a performance output part 25 operated by the power supply voltage; a performance control part 21 that operates with the power supply voltage and causes the performance output part 25 to output performance based on the control information extracted by the demodulation circuit 24. The length of each suspension period for which the base part 1 suspends the power feeding signal for the modulation is such that the power supply voltage can be kept equal to or greater than the minimum operating voltage required to operate the performance control part 21 and performance output part 25.SELECTED DRAWING: Figure 1 |
