INDUCTIVE SENSING TYPE POSITION DETECTION DEVICE

摘要

Disclosed is an inductive sensing type position detection device. The inductive sensing type position detection device according to an embodiment of the present invention includes: a resonator including an LC circuit; a driver for generating a driving signal having a resonant frequency of the LC circuit; an inductive sensor module including a coil pattern part where an oscillation coil which is driven by the driving signal generated by the driver and generates the oscillation signal, a cosine wave receiving coil and a sine wave receiving coil for receiving a signal induced by electromagnetic induction according to an electric signal induced in the resonator as a sine wave and a cosine wave are stacked in a multi-layered structure; and a position detection module which detects at least one of a rotation position and a straight line position of the resonator by analyzing the sine wave. In the resonator, the electric signal can be induced in correspondence to the oscillation signal by the electromagnetic induction.
