摘要： 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.
摘要翻译：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。

摘要： An image forming apparatus includes a main casing; a photosensitive member; a process cartridge that can be installed or removed with respect to the main casing along a removal path; a pick-up roller located above a sheet accommodating portion; and a feed path along which a sheet can be conveyed from the sheet accommodating portion to a discharge port. At least a part of the feed path is substantially parallel to the removal path and located between the sheet accommodating portion and the process cartridge when the process cartridge is installed in the main casing; and an image forming position where an image is transferred from the photosensitive member to the sheet is located along the feed path at a position lower than an upper surface of the pick-up roller in a verticle direction.

摘要： A fixing unit is disposed at a position closer to a rear side wall than to a front side wall of a casing. A top wall is formed with a depressed portion depressed toward inside the casing. The depressed portion serves as a sheet discharge tray for receiving a recording medium that has passed through the fixing unit. The sheet discharge tray includes a tray member detachably disposed at the top wall. The rear side wall is formed with an opening through which the fixing unit is removed. When the tray member is disposed at the top wall, the tray member is positioned above and adjacent to the fixing unit and overlaps the fixing unit when viewed through the opening, thereby preventing the fixing unit from being removed from the casing. The fixing unit is removable through the opening when the tray member is detached from the top wall.
摘要翻译：固定单元设置在比壳体的前侧壁更靠近后侧壁的位置。顶壁形成有朝向壳体内侧凹陷的凹部。凹部用作用于接收通过定影单元的记录介质的片材排出托盘。片材排出托盘包括可拆卸地设置在顶壁处的托盘构件。后侧壁形成有开口，固定单元通过该开口被移除。当托盘构件设置在顶壁时，托盘构件定位在定影单元的上方并与其相邻，并且在通过开口观察时与定影单元重叠，从而防止定影单元从壳体移除。当托盘构件与顶壁分离时，固定单元可通过开口移除。

摘要： A fixing unit of an image-forming device having a heating roller, a pressure roller disposed in confrontation with the heating roller, and a case that rotatably supports the heating roller on both longitudinal ends thereof and covers the heating roller from the side opposite the pressure roller, while leaving the pressure roller exposed. A pair of pressure roller support plates, one end of which is supported on the case, rotatably supports both ends of the pressure roller. With this construction, a more compact fixing unit can be achieved than when the case is configured to cover the heating roller and pressure roller entirely. The fixing unit includes a temperature fuse for restraining abnormal temperature rises in the heating roller, and a temperature fuse cover that extends from an inner wall of the case to provide insulation between the temperature fuse and the heating roller. By integrally forming the temperature fuse cover with the case, it is possible to reduce the manufacturing costs of the fixing unit. Support members may also be provided between a bottom surface of the case and the temperature fuse cover to restrain deformation of the temperature fuse cover.
摘要翻译：具有加热辊，与加热辊对置设置的加压辊的图像形成装置的固定单元以及在两个纵向端部可旋转地支撑加热辊的壳体，并且从与压力相反的一侧覆盖加热辊滚筒，同时离开压辊暴露。一对压力支承板，其一端支撑在壳体上，可旋转地支撑加压辊的两端。通过这种结构，可以实现比将壳体完全覆盖加热辊和压力辊时更紧凑的固定单元。定影单元包括用于抑制加热辊中的异常温度升高的温度保险丝，以及从壳体的内壁延伸以在温度保险丝和加热辊之间提供绝缘的温度保险丝盖。通过与壳体一体地形成温度保险丝盖，可以降低定影单元的制造成本。也可以在壳体的底表面和温度保险丝盖之间设置支撑构件，以限制温度保险丝盖的变形。
