Abstract

PURPOSE:To close a longitudinal opening without hindering a passage of a disk and the like by a method wherein the longitudinal opening is covered by a valve body which may be moved in or out of the longitudinal opening from a side thereof. CONSTITUTION:A valve body 12 is driven by a driving device 11 at the front part of a longitudinal opening 7 along with a valve frame 15. Then, a pair of cylinders acting as a pressing means 13 are extended to push the pressing extension member 12b, thereby the valve body 12 is closely contacted to the front circumferential edge of the opening 7 and closes the same. When the opening 7 shows a relative long length and the valve 12 is not apt to provide a close contact to the valve 12 by a pair of cylinders, the valve 12 is bent and projected toward the opening 7 by a bending projection device 21 in advance so as to form a resilient deformation part which is made flat when it is pushed by the cylinders, thereby it is possible to prevent the valve 12 from being released from the front circumferential edge of the opening 7.
