Abstract: In a printer, a scanner unit is formed into a taper shape having a thinner thickness on a side of a pick-up roller in a removing direction of a process unit, to allow the process unit to be removed from the printer. A part of a sheet feeding path is formed in an area between the process unit and a sheet cassette. An image forming position on the sheet feed path is set lower than an upper end of the pick-up roller. Thus, removal of the process unit can be readily performed. Further, the height of the printer at a position of the pick-up roller can be reduced as compared with a case where the scanner unit is not formed into a taper shape.
Abstract translation: 在打印机中，扫描器单元在处理单元的移除方向上形成为具有较薄厚度的锥形形状，以使处理单元从打印机移除。 片材馈送路径的一部分形成在处理单元和片材盒之间的区域中。 送纸路径上的图像形成位置被设定为低于拾取辊的上端。 因此，可以容易地进行处理单元的移除。 此外，与扫描器单元未形成为锥形的情况相比，可以减小打印机在拾取辊的位置处的高度。

Abstract: In an image forming apparatus, a sensing body is disposed at a first position when a cartridge has been removed from an apparatus body, is disposed at a second position when a first part of the sensing body contacts a housing of the cartridge that has been mounted in the apparatus body, and is disposed at a third position when a second part of the sensing body contacts a movable member of the cartridge that has been mounted in the apparatus body. A judging unit determines that the cartridge has been removed from the apparatus body if the sensing body is at the first position, determines that the cartridge has been mounted in the apparatus body if the sensing body is at the second position, and determines that the cartridge is a new product if the sensing body is at the third position.

Abstract: A fixing device for fixing a developed image of developer onto a recording sheet by heating and fusing the developer includes a heating roller, a pressure roller and a driving force input element. The heating roller is configured to be heated by a heat source, such as a halogen heater. The pressure roller is disposed adjacent to the heating roller, such that a recording sheet is fed and conveyed between the pressure roller and the heating roller. The driving force input element is fixed to the pressure roller for causing the pressure roller to rotate. A diameter Dp of the pressure roller and a nip width N between the heating roller and the pressure roller in circumferential directions thereof have a relationship represented by the following expression: 0.24

Abstract: A fixing device has a frame, a heating roller, a press roller, a peeler, a guide member, and a wheel. The heating roller includes a roller rotation axis and a cylindrical surface. The press roller is pressed against the cylindrical surface to feed a recording medium together with the heating roller along a feeding path. The peeler has a peeling surface having a leading edge, where the peeling surface faces the feeding path. The guide member faces the peeling surface to guide the recording medium to downstream of the feeding path. The guide member is movable between a near position and a far position relative to the peeling surface. The wheel is positioned in a manner that a part of the circumferential edge protrudes from the peeling surface to the guiding member in a virtual plane perpendicular to the wheel rotation axis.
