Controller of light-operated toy

A control device for optically controlled toy consists of a light emitter, a light receiver and a mechanical transmission device, wherein audio frequency analog integrated blocks are respectively connected in the light emitter and the light receiver, so when the light emits light, sound can simultaneously be sent out; in the light receiver, a pair of (two) light sensors are respectively connected to two arms of the bridge circuit. Natural light exerts equivalent effect on the two light sensors, so the bridge circuit is in equilibrium and no signal is sent out, therefore the mechanical transmission device remains still; however, when light sent out by the light supply radiates on the light sensor of the receiving window, the bridge circuit can output signals to start the mechanical transmission device. The light emitter can be used not only as a remote control for an optically controlled toy, but also, independently, as an acousto-optic toy. The control device for optically controlled toy renders the toy with more recreational and interesting properties and can effectively resist interference of natural light. The utility model has the advantages of convenient assembly, practical use and low cost.
