Patent number: 7311378Abstract: A wiping apparatus has a cover box which covers at least a feeding reel, a take-up reel, a wiping member and a spray head, as well as a sheet-feeding passage for the wiping sheet. The passage extends from the feeding reel to the take-up reel. The cover box has formed therein a member opening through which the wiping member protrudes.Type: GrantFiled: February 21, 2005Date of Patent: December 25, 2007Assignee: Seiko Epson CorporationInventors: Kazuyoshi Fujimori, Koichiro Komatsu, Toru Shirasaki

Patent number: 7219976Abstract: A wiping unit is provided that wipes a droplet discharge head included in a droplet discharge unit and reduces the likelihood or prevents a cleaner to be sprayed to a wiping sheet from getting dispersed and adhering to peripheral units. A wiping unit included in a droplet discharge unit is provided with a charged electrode, an absorption electrode, and a static elimination brush. A cleaner sprayed by a cleaner spray head is electrically charged by the charged electrode. The charged cleaner is absorbed toward the absorption electrode, and adheres to a wiping sheet that is placed just before the absorption electrode. Accordingly, it is possible to reduce the likelihood or prevent the cleaner from getting dispersed and adhering to peripheral units.Type: GrantFiled: February 17, 2005Date of Patent: May 22, 2007Assignee: Seiko Epson CorporationInventors: Toshimasa Mori, Kazuyoshi Fujimori

Patent number: 5663852Abstract: A disk drive suitable for receiving removable, cartridge-based media including a movable shutter, comprising a cartridge holder having a bottom guiding area divided into two sections along the side of the cartridge, along with a shutter guide formed therebetween near a central rotary drive used to position the media within the cartridge. The shutter guide guides the cartridge shutter upward from the central rotary drive when a cartridge is either being inserted into or extracted from the holder. Therefore, the cartridge can always be extracted even when the cartridge shutter comes close to the rotary drive due to its own weight and without being directly guided by the cartridge holder.Type: GrantFiled: December 27, 1995Date of Patent: September 2, 1997Assignee: Seiko Epson CorporationInventors: Kazuyoshi Fujimori, Noboru Yamada

Patent number: 5610782Abstract: There are disclosed recording/reproducing devices for use with computers and particularly for recording or reproducing desired information on or from recording mediums like floppy disks, the devices being miniaturized and reduced in thickness for adapting themselves to the miniaturized computers of nowadays. The reduction in device thickness involves the use of a small-sized rare earth group magnet and neodymium ferrous boron which have good magnetic properties as rotor magnets of disk and carriage driving motors; or alternatively planar superpositions are avoided when placing the disk driving motor and the carriage or a carriage guide shaft and a circuit board. The thinned recording/reproducing devices contribute to diminishment of a space for accommodating the computer to meet a demand for miniaturization thereof. A plurality of miniaturized recording/reproducing devices of the invention can be set in the existing space for placement.Type: GrantFiled: November 17, 1995Date of Patent: March 11, 1997Assignee: Seiko Epson CorporationInventors: Aruga Tomoe, Hideya Yokouchi, Kazuyoshi Fujimori

Patent number: 4387643Abstract: A small printer using character wheels is provided. The printer includes a plurality of character wheels frictionally mounted on a shaft for rotation therewith and having a ratchet wheel on side surface. Associated with each character wheel is a pivotable selector pawl actuatable by an electromagnet. The number of electromagnets is less than the number of selector pawls and character wheels. Stopper cams are actuatable into locking engagement with the ratchet wheels on even-numbered character wheels when the shaft begins to rotate. Only odd-numbered character wheels are caused to rotate with the shaft. The desired characters on the odd-numbered character wheels are selected when the electromagnets are energized selectively to move the selector pawls into locking engagement with the ratchets on the odd-numbered character wheels. During the next revolution of the shaft, the stoppers are retracted, that is, out of engagement with the ratchets on the even-numbered type wheels.Type: GrantFiled: December 28, 1981Date of Patent: June 14, 1983Assignees: Shinshu Seiki Kabushika Kaisha, Kabushiki Kaisha Suwa SeikoshaInventors: Hitoshi Mikoshiba, Kazuyoshi Fujimori, Kenji Onodera, Shin Takeuchi

Patent number: 4182576Abstract: An ink-ribbon reversing device for use in a printing machine having an ink-ribbon winding mechanism is provided. The device includes two ink-ribbon spools and associated spool gears mounted on separate spool shafts spaced apart from each other. A drive shaft is positioned between the spool gears with an arm rotatably mounted thereon. A first gear is fixed to the drive shaft. A second gear rotatably mounted on one end of the arm is in engagement with the first gear. One of two actuatable change-over levers abuts the free end of the arm to maintain engagement between the second gear and one spool gear to drive the associated ribbon spool. At the completion of ribbon winding, the change-over lever is displaced, releasing the arm which rotates about the drive shaft to abut the other change-over lever and engage the second gear with the other spool gear to drive the associated ribbon spool.Type: GrantFiled: June 23, 1977Date of Patent: January 8, 1980Assignees: Kabushiki Kaisha Suwa Seikosha, Shinshu Seiki Kabushiki KaishaInventors: Kazuyoshi Fujimori, Akio Mitsuishi
