Title:
位置検出装置
Document Type and Number:
Japanese Patent JP4151130
Kind Code:
B2
Abstract:
There is provided a position detector including a member having a surface and a plurality of vertically and horizontally arranged antennas; a controller for sequentially driving the vertically arranged antennas in vertical positive and vertical negative directions, and for sequentially driving the horizontally arranged antennas in horizontal positive and horizontal negative directions so that the antennas sequentially radiate radio waves; a receiver for receiving the sequentially radiated radio waves on the surface of the member; and a detector for detecting the position of the receiver on the surface of the member based on the levels of the received radio waves. The detector detects the position of the receiver as an average position for a first position detected based on the levels of the radio waves which are sequentially radiated in the vertical positive and horizontal positive directions, and a second position detected based on the levels of the radio waves which are sequentially radiated in the vertical negative and horizontal negative directions. Therefore, since the receiver position detected by the detector does not vary, no delay time adjustment circuit is required, and the position of the receiver can be accurately detected.
