摘要： This invention relates to a drive switching mechanism for use in an image input apparatus. While a pivotable gear is set on the side of a document feeder, a displacement restricting mechanism of the drive switching mechanism restricts a displacement of the pivotable gear toward an image scanner. With this arrangement, even if the pivotable gear is caused to move toward the image scanner while set on the side of the document feeder, a stopper of the displacement restricting mechanism restricts such movement to maintain an engaged state of the pivotable gear with a drive gear of the document feeder. Accordingly, a driving force of a motor rotatable in the opposite direction (forward and backward) can securely be transmitted to the drive gear of the document feeder via a non-pivotable gear and the pivotable gear. The same operation and effect as on the side of the document feeder is obtainable on the side of the image scanner.
摘要翻译：本发明涉及用于图像输入装置的驱动切换机构。当可摆动的齿轮设置在文件进给器的侧面时，驱动切换机构的位移限制机构限制可枢转的齿轮向图像扫描器的位移。通过这种布置，即使可摆动齿轮被设置在文件进给器侧面而朝向图像扫描仪移动，位移限制机构的止动器限制这种运动，以保持可枢转齿轮的接合状态与驱动齿轮的送纸器。因此，可以通过不可枢转的齿轮和可枢转的齿轮将能够沿相反方向（前后）旋转的马达的驱动力牢固地传递到送纸器的驱动齿轮。在图像扫描器的一侧可获得与文件馈送器侧相同的操作和效果。

摘要： In an image forming apparatus where a transfer roller is arranged to be out of contact with a photoreceptor drum, a guide member for guiding a transfer sheet so as to abut the photoreceptor drum at a predetermined angle and an auxiliary guide member for supporting the transfer sheet to prevent the rear end of the transfer sheet separated from the end of the guide member from being weighed down are arranged close to the photoreceptor drum. Further, to supply a conveying force to the transfer sheet until the rear end of the transfer sheet is separated from the guide member, a conveying roller is arranged opposite to the upper surface of the guide member where the transfer sheet passes.

摘要： This invention relates to an image forming apparatus and a method for assembling the apparatus. A main body of the image forming apparatus has a frame main body consisting of an optical frame and a chassis made of a resin (resin chassis). Mounting an image recorder unit on the resin chassis improves the precision in mounting the image recorder unit, while the optical frame assuring the rigidity of the apparatus as a whole. The resin chassis consisting part of the frame main body reduces the production cost of the frame main body, in turn, reducing the production cost on the final product, i.e., image forming apparatus.
