摘要： In a transfer type electrophotographic copying apparatus having a rotatable photosensitive drum for receiving an electrostatic latent image of an original and a heating device comprising a heating roller and a pressure-contact roller rotatable in a condition of pressure-contact with the heating roller for fixing a toner image of the original on a transfer paper moved along a path including a position of image transfer contact with the drum and then between the rollers, the distance from the contact position of the transfer paper with the drum to the pressure-contact point of the heating and pressure-contact rollers being less than the length of the transfer paper as measured in the direction of movement of the paper along the path.

摘要： In a copying machine in which the distance of projection scanning is varied by relative movement between the copy board and the optical system in accordance with the size of the original, indices are provided on the copy board for positioning the original so that the shorter side of the original always corresponds to the direction of scanning. This unification of original placement results not only in a shortening in the distance of the projection scanning but an increase in copying speed.
摘要翻译：在投影扫描的距离根据原稿的尺寸在复制板和光学系统之间的相对移动而变化的复印机中，在复印板上设置有用于定位原稿的索引，原来总是对应扫描的方向。这种原始放置的统一不仅在投影扫描的距离缩短，而且复印速度的增加。

摘要： An electrophotographic reproducing machine wherein an integrally formed dish-like housing for an exposure optical system is mounted onto a machine frame which accommodates therein a plurality of process units for reproducing and is opened upward, and a document glass plate is mounted at the top portion of the housing for the exposure optical system through glass mounting plates. The housing accommodates therein a slit plate for scanning of an exposure lamp, a projection lens, which is formed in its peripheral walls with vent holes for promoting ventilation within the machine and which has at its bottom portion a shield bottom wall serving as also a heat insulating plate. Guide rail surfaces for guiding movable mounts of the optical system are formed on both side walls of the housing opposite to each other. A projection lens mounting seat is integrally formed substantially at the center of the bottom wall of the housing, and a shield box raised upward from the bottom wall is integrally formed on the bottom wall at a position adjacent to the production lens mounting seat.
摘要翻译：一种电子照相再现机，其中一体形成的用于曝光光学系统的碟形壳体安装在机架上，该机架上容纳有多个用于再现的处理单元并向上打开，并且文档玻璃板安装在通过玻璃安装板的曝光光学系统的外壳。壳体中容纳有用于扫描曝光灯的狭缝板，在其周壁上形成有用于促进机器内的通风的通气孔的投影透镜，并且在其底部具有也用作热量的屏蔽底壁绝缘板。用于引导光学系统的可移动安装件的导轨表面形成在壳体的相对的两个侧壁上。投影透镜安装座基本上位于壳体底壁的中心处，并且在靠近生产镜头安装座的位置处在底壁上一体地形成从底壁向上凸起的屏蔽盒。

摘要： An electrophotographic reproducing apparatus in which a reproducing apparatus body unit including an electrostatic latent image receptor such as a photosensitive member and other electrophotographic treating device is assembled in advance whereas an optical scanning unit including at least a document illumination lamp, a group of mirrors and a group of focusing lenses is assembled in advance in a predetermined positional relationship to the reproducing apparatus body unit, and both the units thus assembled are jointed at predetermined reference planes to each other and so integrated that they can be driven cooperatively with each other. Said two units further include jointing device at their respective predetermined reference planes.
