Patent number: 5374947Abstract: A laser beam printer capable of changing the printing speed and quality. The laser beam printer includes a speed decoding unit for decoding a specification of the printing speed, and a speed setting unit for setting a transport speed for a sheet of paper taken as an object of recording in accordance with decoded contents of the printing speed.Type: GrantFiled: May 18, 1992Date of Patent: December 20, 1994Assignee: Fuji Xerox Co., Ltd.Inventors: Kazuhiko Takahashi, Yukinori Sezaki, Hideki Furuta

Patent number: 5268724Abstract: A transfer apparatus including a photoreceptor drum having a transfer position, feeding rollers for feeding out a sheet of paper upward obliquely, and a guide member provided between the feeding rollers and the photoreceptor drum and having a guide surface on a lower surface thereof to guide the paper to the transfer position along the guide surface. In the transfer apparatus, the structure is simplified since the paper is guided by the single guide member. Moreover, the feeding of the paper can be performed smoothly, since frictional resistance is produced only on one side of the paper. In addition, the guide surface is formed on the lower surface of the guide member, so that the paper can be supplied to the transfer position of the photoreceptor drum stably.Type: GrantFiled: November 19, 1992Date of Patent: December 7, 1993Assignee: Fuji Xerox Co., Ltd.Inventors: Hiromitsu Koizumi, Yukinori Sezaki
