DEVICE FOR MOVING TRANSMISSION COIL IN CONTACTLESS CHARGER

摘要

PROBLEM TO BE SOLVED: To obtain a device for moving transmission coils of a contactless charger, capable of efficiently moving transmission coils to positions for efficient charge, even at readily positioning of electronic equipment including built-in power receiving coils in the contactless charger, and capable of being thinned. SOLUTION: The moving device includes: a link table attached to a baseplate slidably and movably in an X direction; an X-direction moving mechanism for allowing an X-axis control motor to slide and move the link table in an X direction; a Y-direction moving mechanism including a screw shaft rotated by a Y-axis control motor attached to the link table to position a shaft center in a direction perpendicular to a moving direction in the X direction; a power transmission coil support including a power transmission coil moving in a Y direction by the forward/reverse rotation of the screw shaft in the Y-direction moving mechanism; a detection sensor for detecting the position of a power receiving coil in the electronic equipment including the built-in power receiving coil; and an operation control circuit that moves the power transmission coil to a detected position and operates the X- and Y-direction moving mechanisms.
