PURPOSE: A belt control device is provided to enable a worker to recognize the rotation angle of a roller by adjusting the angle of the roller and visually displaying the adjusted angle of the roller. CONSTITUTION: A belt control device comprises a roller unit (10), varying units (20), and display units (30). The roller unit is wound around a belt. The varying units are installed on both ends of the roller unit and vary the position of the roller unit. The display units are connected to the varying units and visually display the position of the roller. Each of the varying units comprises a fixed frame (21), a moving body (22), and a length adjusting body (23). The moving body slides along the fixed frame, and the end of the roller unit is installed thereon. One end of the length adjusting unit is coupled to the fixed frame, and the other end is coupled to the moving body. |
