Patent number: 8967075Abstract: When the coating object area is positioned on the suction table, the film is stopped and is mounted on the suction table, and is further provided with tension in the longitudinal direction to eliminate slacks or the like, but, curl is caused in the both side end regions in the coating object area. Therefore, the coating object area is mounted on the suction table, and at the same time, the curl correction bars disposed on the both sides of the suction table are moved to the curled portions of the coating object area, and then the curled portions are pressed against the suction surface of the suction table to thereby perform the curl correction. Further, in the coating process with the UV-curing coating material, the UV light from the UV light source formed integrally with the coating head is applied to cure the material. In the vacuum suction section, as the destination, the bubbles or the like in the coating head are sucked.Type: GrantFiled: October 28, 2010Date of Patent: March 3, 2015Assignee: Hitachi, Ltd.Inventors: Yoshitsugu Miyamoto, Toshiharu Kishimura, Hitoshi Manabe, Katsuyoshi Watanabe, Naoki Watase, Hideo Nakamura

Patent number: 4346289Abstract: The device of the invention is assembled in a paper sheet counting apparatus to stop and held the suction heads at the predetermined positions at which one of the suction heads is precisely opposite to the face of the paper sheet in the face-to-face relationship. The suction heads are carried by a rotary cylinder having peripheral face on which a group of recesses each corresponding to each of the suction heads is formed. One of the recesses receives a pawl of a stopper when the rotary cylinder is stopped to terminate the paper sheet counting operation. The stopper is held at a retracted position when the counting operation is continued and moved to an engaging position when the one cycle counting operation is terminated. A slipping slope diverges from each recess outwards. The stopper is provided with an elongated hole in which a shaft is inserted, and the stopper is swinged about the shaft to be moved between the retracted position and the position to be engaged with one of the recesses.Type: GrantFiled: June 4, 1981Date of Patent: August 24, 1982Assignee: Laurel Bank Machine Co., Ltd.Inventors: Tuyoshi Miyagawa, Hitoshi Manabe
