PURPOSE: A telescopic conveyor device is provided to enable effective lifting motion with small power because the height of a movable frame is controlled by lifting the rear end of the guide frame with a lifting unit. CONSTITUTION: A telescopic conveyor device comprises a base frame(100), a guide frame(200), a movable frame(300), a moving unit, a conveyor belt(500), and a first motor(600). A driving pulley(220) and a first driven pulley(230) are arranged in the longitudinal rear end and front end of the guide frame, respectively. The guide frame is supported by the base frame. A second driven pulley(320) and a third driven pulley are arranged in the longitudinal front end and rear end of the movable frame. The movable frame is installed inside the guide frame so that both side ends thereof can be supported and guided by the guide frame. The moving unit draws in and out the movable frame from the guide frame. The first motor runs the driving pulley.
