摘要： An image-forming machine includes an image-forming unit, a transfer belt assembly disposed beneath the image-forming unit so as to freely ascend and descend between an acting position and a non-acting position, and a lift device for asending and descending the transfer belt assembly. The transfer belt assembly includes a driven roller, a tension roller, an endless belt wrapped around the driven roller and the tension roller, and a resilient urging device for resiliently urging the tension roller toward a direction of applying tension to apply tension to the endless belt. A tension release device is disposed which, when the transfer belt assembly is descended to the non-acting position, moves the tension roller in the direction in which tension is no longer applied, against a resilient urging action of the resiliently urging device, so that the application of tension to the endless belt is discontinued. A tension release invalidation device is further disposed to invalidate the tension release action of the tension release device upon detecting the manual operation for drawing out the image-forming unit from a required acting position when the tension release device discontinues the application of tension to the endless belt.

摘要： Bypass sheet-feeding section for an electro-statographic image reproducing apparatus employing vertical sheet transport from sheet supply cassettes to the image reproducing section. The bypass sheet-feeding section serves to hold special copying sheets such as cardboard, OHP sheets, and surface-coated paper; but it can also serve to hold a stack of, for example, conventional-sized copy paper. The bypass/stack sheet-feeding section is fitted with drawer guides, and includes a sheet-loading plate, a sheet-feeding pickup roller, a sheet-feed plying roller pair and a mechanism for moving the loading plate vertically. The bypass/stack sheet-feeding section can be withdrawn integrally when it is pulled out from the side of the copier main unit. In an electrostatographic image reproducing apparatus configured in accordance with the invention, at least the document table, the document-reading section, the sheet-feeding cassette installation section, and the bypass sheet-feeding section are arranged vertically in the copier casing into positions approximately stacked from a plan aspect. Thus the occupied installation area is significantly reduced.
