AN PRESENTATION ELECTRONIC PAD FOR SUPPORTING INTERGRATED-TYPE MULTIBOARD

摘要

An electronic pad connected to a computer to display writing contents on the computer screen, the electronic pad comprising: a tip part for discharging ink upon contact with a paper surface, a pressure sensor part detecting a ground contact of the tip part, and outputting a detection signal; A pen unit including a first infrared ray transmitting unit and a first ultrasonic wave transmitting unit, a pad unit formed in a plate shape, and having a control bar for controlling a presentation display on one side, and a clip unit for fixing paper to an upper surface of the pad unit. An infrared receiver configured to receive the infrared rays transmitted from the first infrared transmitter, second and third ultrasonic receivers and the infrared receiver, the first ultrasonic receiver, and the second ultrasonic receiver to receive the ultrasonic waves transmitted from the first ultrasonic transmitter. The distance between the pen unit and the distance of the arrival time between the received infrared and ultrasonic waves; Calculates position coordinates, outputs a mouse control signal and the position coordinates when the position coordinates belong to a preset first region, and outputs a display control signal and the position coordinates when the position coordinates belong to a second preset region And a base unit including a processor configured to transmit a signal output from the processor to the computer.
