<P>PROBLEM TO BE SOLVED: To relatively reduce the number of components. <P>SOLUTION: A position detection device includes: first coil parts 81, 82 and 83 for generating magnetic fields; second coil parts 71, 72 and 73 located at a position that the magnetic fields generated by the first coil parts reach to make the states of both end parts changeable from an open state to a short circuit state and from the short circuit state to the open state; moving parts 32 and 56 which are moved in accordance with the movement of an object to be a target of a position detection and change the states of both the end parts of the second coil parts from the open state to the short circuit state or from the short circuit state to the open state by elastically deforming the second coil parts due to contact with the second coil parts in accordance with the movement; and a detection part for detecting the position of the object on the basis of voltage of the first coil parts. <P>COPYRIGHT: (C)2013,JPO&INPIT |
