摘要:
A cover body hinged to the housing of an electronic duplicator is rotatable between a first and second position so that in the first position a plurality of driven rollers within the cover body are aligned and in contact with a like plurality of driving rollers along an original document carrier path so that thin originals can be transported thereby and in the second position the driven rollers are located on the same level as the driving rollers and form an extension thereof so that thick originals can be transported along the carrier path.
摘要:
A developing device comprising a continuous belt for carrying exposed photosensitive paper, an electrically conductive belt supported to be driven at the same speed in parallel spaced relationship therewith through a developing solution. A number of string-like insulating members are supported on the surface of the conductive belt facing the surface of the carrying belt. The insulating members and the conductive belt are driven into contact with a cleaning member mounted adjacent thereto.
摘要:
An exposure window in an electrostatic copying machine for preventing electrostatic adherence of the advancing copy paper is formed of a flat transparent plate having deep wells in its rear face including a medial equilateral triangular well with its apex toward the plate trailing edge and a group of parallelogram wells on each side of the triangular wells, the wells being separated by thin partitions with parallel walls. The peripheral faces of the wells are perpendicular to the plate faces and the bases of the wells are parallel to the plate faces. The window plate has a guide slope formed on one edge for guiding the entry of a copy paper onto the plate for exposure.
摘要:
A tubular light source for a flow-type duplicating machine provides an image with uniform brightness by making its luminousbrightness stronger around both its sides than around its middle along its longitude. A plurality of electrically conductive materials are disposed more densely in the middle portion of the light than around its end portions.

AN ILLUMINATING DEVICE FOR THE ORIGINAL IN AN ELECTROPHOTOGRAPHIC DUPLICATING MACHINE, WHICH SCANS AND PROJECTS AN IMAGE OF AN ORIGINAL, ILLUMINATED BY A LIGHT SOURCE ON A PHOTO-SENSITIVE PAPER, WHICH DEVICE CAUSES THE IMAGE TO BE UNIFORMLY BRIGHT. THE IMAGE IS FORMED LONGITUDINALLY ON AN EXPOSURE SLIT WHICH IS DISPOSED AT RIGHT ANGLES TO THE SCANNING DIRECTION.
