Patent number: 9156643Abstract: A sheet pressing device enables reliably pivoting a presser lever that presses a sheet material to a feed path surface to a pressure position and a released position. The sheet pressing device has a movable-side presser lever configured to pivot between a pressure position where die-cut label paper conveyed over the feed path surface is pressed by a sheet presser part to a flat surface, and a released position where the sheet presser part is separated from the die-cut label paper; and a lever spring respectively urges the movable-side presser lever to the pressure position or the released position from a neutral point between the pressure position and the released position.Type: GrantFiled: July 25, 2014Date of Patent: October 13, 2015Assignee: Seiko Epson CorporationInventor: Kenichi Hirabayashi

Patent number: 8999108Abstract: In the separation of a cover tape 15e from a carrier tape 15 performed by a cover tape separating mechanism 50, a cover tape 15e, which is separated from a base tape 15a by a separating blade edge 51f, comes into contact with a concave conical surface 52c, so that one side portion of a cover tape 15e is bent toward the other side portion; and the bent cover tape 15e is pressed against a guide surface 32s from below while the carrier tape 15 is guided to a pick-up position. Accordingly, the cover tape 15e is folded on the base tape 15a in a flat shape.Type: GrantFiled: February 3, 2012Date of Patent: April 7, 2015Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Kazuhide Nagao, Nobuhiro Nakai, Yutaka Kinoshita

Patent number: 6450384Abstract: A continuous paper treating apparatus is provided which includes a tractor for feeding continuous paper and a paper treating unit for treating the paper. The tractor includes a driving belt provided with tractor pins, a tractor lid for covering the driving belt, a support base having a paper support surface for supporting the continuous paper. The tractor also includes a presser member supported by the tractor lid. The presser member is variable in position and posture relative to the tractor lid, and has a pressing surface for pressing the paper. In the tractor, use is made of springs for urging the presser member toward the paper supporting surface, so that the pressing surface presses the continuous paper onto the paper supporting surface.Type: GrantFiled: March 20, 2000Date of Patent: September 17, 2002Assignee: Fujitsu LimitedInventors: Kiyoshi Chinzei, Kenichirou Yano

Patent number: 6435393Abstract: A perforated filmstrip transportation and registration system (100) and method provide a substrate in the form of a rotating drum (104) with vacuum holes (106) to allow an internally produced vacuum to act upon an engaged film-strip (102). The rotating drum (104) has a number of registration-tension pin pair assemblies (216) that register and subsequently advance a filmstrip (102) at the 3 o'clock position in a registration mode (FIGS. 2 and 3), and are ready to be inserted in filmstrip perforations (208) when they approach the 3 o'clock position in a load mode (FIG. 4). The registration-tension pin pair assemblies (216) each contain a registration pin (220) and a tension pin (230) which are sized small enough to fit into filmstrip perforations (208) without interference, and which move away and towards each other in the nature of scissors blades in the preferred embodiment.Type: GrantFiled: January 8, 2001Date of Patent: August 20, 2002Assignee: Eastman Kodak CompanyInventors: Richard L. Druzynski, Jeffery R. Hawver

Patent number: 6176411Abstract: A paper transfer apparatus is provided which is incorporated in an electrophotographic printer having a photosensitive drum for printing on elongated paper. The paper transfer apparatus serves to transfer the elongated paper along a transfer path extending via the photosensitive drum. The paper transfer apparatus includes a discharge or scuff roller for pulling the elongated paper in a transferring direction. The discharge roller is spaced downstream from the photosensitive drum. The paper transfer apparatus also includes a pair of tractors for advancing the elongated paper along the transfer path. The tractors are spaced upstream from the photosensitive drum. Each of the tractors is provided with a presser member supported by a tractor lid of the tractor. The presser member serves to apply friction to the elongated paper when the tractor lid is in closed position.Type: GrantFiled: October 15, 1998Date of Patent: January 23, 2001Assignee: Fujitsu LimitedInventor: Seiji Suketomo

Patent number: 5305068Abstract: A printer, for printing on continuous recording paper, includes tractors disposed in the recording paper feed path of the printer, with each of the tractors circumferentially travelling in synchronism with movement of the continuous recording paper when the tractors engage feed holes of the continuous paper. When no printing operation is performed, travel of the tractors can be prevented by operation of an electromagnetic clutch, or a combination of one way clutches. Further, the printer uses an electrophotographic method wherein when no printing operation is performed, a transfer charger or fixing roller can be retracted from an operational position. A lever, associated with movement of the transfer charge or fixing roller, is pressed against and locked with the pulley fixed to the rotating shaft of each of the tractors to thereby prohibit the movement of the tractor.Type: GrantFiled: April 23, 1992Date of Patent: April 19, 1994Assignee: Asahi Kogaku Kabushiki KaishaInventors: Tsutomu Sato, Masatoshi Takano, Taizo Saito, Hiroyuki Yamaguchi

Patent number: 4326656Abstract: Printing platen for positioning a recording medium such as paper which includes an evacuated chamber having a slotted face plate for attracting, holding and guiding the paper. Slots are arranged parallel to each other and the direction of paper travel, and the vacuum attraction causes temporary deformation of the paper so that the slots can effect guiding and tension on the paper during advancement. Effective platen length can be varied to accommodate different paper widths.Type: GrantFiled: June 25, 1980Date of Patent: April 27, 1982Assignee: International Business MachinesInventors: Floyd A.

Patent number: 4091912Abstract: A plurality of clamping members are disposed along a recording line against the record media, and a cable, secured at the ends thereof, is trained in a path engaged with the clamping members and with movable bearing members spaced between the clamping members. Actuation of a solenoid causes a rocker arm to pivot and through a cable tension control member carried thereby cause tightening of the cables on the clamping members and on the bearing elements thereby changing the force on the clamping members and against the record media for holding the media in precise position while recording thereon.Type: GrantFiled: March 17, 1977Date of Patent: May 30, 1978Assignee: Computer Peripherals, Inc.Inventor: James R.
