Patent number: 6594040Abstract: A thermal transfer facsimile apparatus of the type having a transmitting system disposed above a recording system, which construction is compact and allows a user to open a body cover to remove a document jammed in the apparatus with no fear of damaging the document. In the apparatus, a part of an ink-ribbon cartridge serves as a lower guide for supporting a document to be transported, while a part of the body cover, to which a platen and rollers for feeding and delivering recording paper are attached, also serves as a lower guide for the document. When a body cover is opened to replace an ink ribbon with new one or remove a document jammed in the apparatus, a distance formed between a document feeding roller fixed to the body and a lower free end of the body cover is so elongated by virtue of the existence of the guiding part of the cartridge that document may be gently curved and stretched therebetween without being damaged. This can also assure a compact design of the apparatus.Type: GrantFiled: June 21, 1999Date of Patent: July 15, 2003Assignee: Sharp Kabushiki KaishaInventor: Katsuyuki Sakai

Patent number: 5564842Abstract: A recording apparatus includes a roll of recording paper, a roll conveying roller for feeding a roll of recording paper, and a sheet conveying roller for feeding sheets of recording paper. Power from a DC motor is transmitted to both rollers through a switching mechanism. The switching mechanism includes a system gear, a planetary gear, and a planetary gear arm, and a locking member for fixing the planetary gear arm at a prescribed position. A head release cam, a head release pulley, and a timing belt cooperate with the switching mechanism to remove pressure from a print recording head to prevent damage to the head during switching. Accordingly, a roll of recording paper and sheets of recording paper can be selected and used as needed without increasing the manufacturing cost and size of the apparatus.Type: GrantFiled: June 30, 1993Date of Patent: October 15, 1996Assignee: Sharp Kabushiki KaishaInventors: Shigeru Kida, Katsuyuki Sakai, Masaya Kawatsuri, Manabu Sakata

Patent number: 5150630Abstract: A power switching apparatus in accordance with present disclosure includes a sun gear which can be driven to rotate in a first and second direction, an arm which can swing freely relative to the rotating axis of the sun gear. A transfer gear is pivotally provided at the arm for engaging with the sun gear. There is a pair of driven gears disposed a prescribed distance apart from each other in the circumferential direction of the sun gear so that each of said driven gears can engage independently with the transfer gear. A control device controls the position of the transfer gear so that the transfer gear can engage with one of the driven gears before initiation of rotation of the sun gear.Type: GrantFiled: May 21, 1991Date of Patent: September 29, 1992Assignee: Sharp Kabushiki KaishaInventors: Shigeru Kida, Katsuyuki Sakai

Patent number: 5077618Abstract: A facsimile apparatus has a single conveying roller in it, above which an image sensor is set and below which a printing head is set. Pressing pins are set respectively near the upper and lower ends of components supporting the conveying roller to freely rotate. In transmission, the lower pressing pins keep away the printing head from the conveying roller and the image sensor presses an original document onto the conveying roller. In reception, the upper pressing pins keep away the image sensor from the conveying roller and the printing head presses the recording paper onto the conveying roller. In this way, structure of the facsimile apparatus is simplified.Type: GrantFiled: November 6, 1989Date of Patent: December 31, 1991Assignee: Sharp Kabushiki KaishaInventors: Katsuyuki Sakai, Kenichi Shiraishi, Motohiko Hayashi, Sadaaki Shimonaga
