F-PCB WINDING DEVICE FOR A PORTABLE TERMINAL, PARTICULARLY FOR WINDING OR UNWINDING AN F-PCB COMPOSED IN A MAIN BODY OF THE PORTABLE TERMINAL WITH A SLIDING TYPE ACCORDING TO THE ROTATION OF A ROTATING ROLLER

摘要

PURPOSE: An F-PCB(Flexible-Printed Circuit Board) winding device for a portable terminal is provided to improve the function of an F-PCB by winding or unwinding the F-PCB composed in a main body of the portable terminal with a sliding type according to the rotation of a rotating roller. CONSTITUTION: A pair of fixed caps(200) are fixed at a certain position within an upper casing frame of a main body. A torsion cylinder(300) is fixed between the fixed caps(200). A rotating roller(400) is rotatably combined to the external circumference of the torsion cylinder(300). The rotating roller(400) rotates clockwise or counterclockwise centering around the axis of rotation of the rotating roller(400) along the sliding movement of a slide body, and winds or unwinds an F-PCB(600). A coil spring(500) composed in the torsion cylinder(300) provides an elastic force to be capable of rotating the rotating roller(400). The F-PCB(600) is combined to the torsion cylinder(300) and the rotating roller(400) to be penetrated. The F-PCB(600) is wound or unwound along the rotation of the rotating roller(400).
