POSITION MEASURING DEVICE AND POSITION INFORMATION INPUT SYSTEM USING SAME

摘要

Disclosed are a position measuring device capable of precisely measuring a position of an electronic pen tip, and a position information inputting system using the same. The position measuring device includes: 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. Under such configuration, the position measuring device can enhance reliability by precisely measuring positions of characters or symbols to be input to an electronic device having a screen, and can enhance a user's convenience by reducing time taken to input characters or symbols by preventing an erroneous operation.
