1. A wireless charger installed with a moving part comprising:
- a lower case, where a first coil is positioned; and
an upper case which covers the lower case, the upper case comprising a top surface; and
the moving part, whereinthe first coil is moved near to a charge battery by the moving part and the charge battery is charged by supplying power from the first coil towards the charge battery when the charge battery attached with a second coil is set on the top surface of the upper case;
the moving part comprises;
a first drive part comprising an X axis motor which moves an X axis slider in an X axis direction along an X axis guide;
a second drive part comprising a Y axis motor which moves a Y axis slider in a Y axis direction along a Y axis guide; and
a table which moves in the X axis direction and the Y axis direction by a movement of the X axis slider and the Y axis slider;
whereinthe X axis slider includes a rack parallel to the X axis guide and an extension part parallel to Y axis;
the Y axis slider includes a rack parallel to the Y axis guide and an extension part parallel to X axis;
the table comprises;
a slider base attached to the X axis slider and the Y axis slider, and which moves in the X axis direction along the extension part of the Y axis slider when the X axis slider moves in the X axis direction, and moves in the Y axis direction along the extension part of the X axis slider when the Y axis slider moves in the Y axis direction; and
a table body fixed to the slider base, and the first coil attached to a top surface of the table body;
the first drive part further comprises a pair of X axis pinions arranged at a location to simultaneously mesh with teeth near both ends of a rack of the X axis slider, and the pair of X axis pinions are driven by the X axis motor and rotated in synchronization when the X axis slider is located at the center of a moving range;
the second drive part further comprises a pair of Y axis pinions arranged at a location to simultaneously mesh with teeth near both ends of a rack of the Y axis slider, and the pair of Y axis pinions are driven by the Y axis motor and rotated in synchronization when the Y axis slider is located at the center of a moving range;
the slider base includes a hole passing through the slider base in an X axis direction and a plurality of L shaped leg parts arranged on a bottom of the slider base and projecting downward from the bottom of the slider base;
the hole is slidably attached to the extension part of the Y axis slider;
at least one of the plurality of L shaped leg parts is arranged to be opposed to the other L shaped leg parts; and
the plurality of L shaped leg parts are slidably attached to the extension part of the X axis slider.

Abstract
A wireless charger installed with a two-dimensional moving mechanism which is simply configured, inexpensive and can be easily miniaturized is provided wherein a table is freely moved in the X-axis direction and the Y-axis direction. In the two dimensional moving mechanism, each pair of X axis pinions are arranged to simultaneously mesh with teeth near both ends of each rack arranged on an X axis slider and Y axis slider respectively. Each pair of pinions are driven by each motor and rotated in synchronization.
