Patent number: 7251436Abstract: An armored unit includes a side cover and a guide member. When sheet jam operation is carried out, a fixing unit is pulled out with the armored unit, and then is pushed to the rear side. This operation unlocks the lock member provided in the guide member, and a shoulder screw moves in a guide hole. Thus, the fixing unit is moved from the pulled out position toward the rear side and toward the main body of image forming device to be shifted to a receding position. On this account, it is possible to provide an image forming device ensuring sufficient space for removing a jammed sheet by hand with a small opening space.Type: GrantFiled: November 22, 2002Date of Patent: July 31, 2007Assignee: Sharp Kabushiki KaishaInventors: Yasunori Minakuchi, Atsushi Ide, Yoshinobu Tateishi, Kazuhiro Matsuyama, Toshiya Mikita, Koichi Yamauchi, Hiroshi Tachiki, Koichi Nakamura, Norio Tomita

Patent number: 6647228Abstract: In an image forming device of the present invention, which is a tandem type, electrophotographic image forming device, a first separating/contacting mechanism mechanically lowers/raises the whole of a transfer frame holding the transfer and transport belt unit in association with the opening/closing of a front door, a second separating/contacting mechanism mechanically lowers/raises the right side of the transfer frame in association with the opening/closing of a right side door, and a third separating/contacting mechanism mechanically lowers/raises the left side of the transfer frame in association with the opening/closing of a left side door. Therefore, the handling of a paper jam can be carried out even when power supply is cut off, and the transfer frame can be separated from the photoconductor drums just by opening a door from a plurality of access directions, on a side opened.Type: GrantFiled: January 22, 2002Date of Patent: November 11, 2003Assignee: Sharp Kabushiki KaishaInventors: Koichi Nakamura, Koichi Yamauchi, Mitsuyoshi Terada, Tadasu Taniguchi, Hideaki Kadowaki, Yoshikazu Harada, Hiroshi Tachiki
