Claim Text:
1. A position measuring device, comprising: a position measuring unit configured to measure a position of a tip of an electronic pen using a reference signal and ultrasonic signals, and configured to input position information on the electronic pen tip to an electronic device; a housing where the position measuring unit is installed; and a coupling means having one end connected to the housing, and another end coupled to the electronic device, so as to couple the housing to one side of the electronic device, wherein the coupling means includes: an insertion member inserted into one side of the electronic device; and a connection member positioned at one side of the insertion member, and connected to the housing, wherein the housing includes: a rear cover which forms an appearance of the housing; a circuit board accommodated in the rear cover, and electrically-connected to the insertion member when the connection member is fixedly-coupled to the circuit board; and a front cover coupled to a front side of the rear cover, wherein the insertion member is provided with connection terminals on two surfaces thereof, so as not to have directivity when the position measuring device is connected to the electronic device, wherein a supporting member, having an exposure hole through which two surfaces of the insertion member are exposed to outside, is provided at one side of the front cover, the supporting member configured to support a circumferential surface of the insertion member which forward protrudes from the front cover in a penetrating manner, and wherein the supporting member is provided with a non-conductive sheet which is inserted into one side surface of the supporting member, such that a non-used connection terminal provided on one surface of the insertion member is shielded from outside.
