REMOTE CONTROLLER EQUIPPED WITH TRACK BALL MODULE

摘要

PURPOSE: A remote controller, which track ball module is mounted, is provided to perform a game function by a remote controller, thereby improving an operating feeling of keys. CONSTITUTION: A track ball(510) controls an IPTV by connecting with a keypad module. A sensing block(520) senses rotation and pressure of the track ball. A PCB(Printed Circuit Board) substrate(530) controls a signal of the sensing block. A connector module(540) transmits a signal of the sensing block to a IR(Infrared Ray) transceiving unit. According to an input signal of the keypad module and the track ball module, the IR transceiving unit remotely transmits a signal by the IPTV.
