摘要： A document reading apparatus comprises a contact type image sensor having a protection glass located at a surface where a document is to be read, first roller mechanism for supplying a document which is to be read in a document transport direction on the protection glass of the contact type image sensor, a platen roller which is rotatably supported at a position confronting the protection glass, a support mechanism for rotatably supporting the platen roller, and a restricting mechanism. The support mechanism permits a movement of the platen roller in a predetermined direction which is approximately perpendicular to a surface of the protection glass depending on a thickness of the document which is supplied between the platen roller and the protection glass by the first roller mechanism. The restricting mechanism restricts a position of the platen roller to a predetermined position when no document is inserted between the platen roller and the protection glass so that a predetermined gap is formed therebetween.

摘要： A paper feeder for feeding papers to an image forming apparatus and a paper tray elevation device therefore are disclosed. A first tray is movable up and down with a plurality of papers stacked thereon. A paper feed member feeds the papers from the first tray in a preselected direction of paper feed. A second tray is positioned beside the first tray in substantially the horizontal direction and movable up and down with a plurality of papers stacked thereon. A shifting device shifts the entire paper stack from the second tray to the first tray. A horizontal elevating mechanism elevates the first tray while maintaining it in substantially the horizontal position. An interlocking mechanism at least elevates, when papers of greater in size than the papers to be stacked on the first or second tray are stacked over the first and second trays in a single stack, the second tray in interlocked relation to the elevation of the first tray while maintaining the second tray in substantially the horizontal position. The papers of greater size are capable of being stacked over the first and second trays and fed by the paper feed member.

摘要： A stencil printer includes an ink drum having a hollow cylindrical porous support and a pair of flanges supporting opposite ends of the support. Annular elastic members are respectively affixed between the inner periphery of the porous support and the outer circumferences of the flanges. When the ink drum is pressed against a press roller, the elastic members deform and cause an ink roller disposed in the ink drum to be displaced. As a result, the ink roller contacts the inner periphery of the porous support brought into contact with and positioned by the press roller. The ink roller and the inner periphery of the ink drum can therefore contact each other under uniform pressure without the rigidity of the drum being reduced and without any shaking.

摘要翻译： 模版印刷机包括具有中空圆柱形多孔支撑件和支撑支撑件的相对端部的一对凸缘的墨水鼓。 环状弹性构件分别固定在多孔载体的内周边和凸缘的外周之间。 当墨辊被压靠在压辊上时，弹性构件变形并使设置在墨盒中的墨辊移位。 结果，墨辊接触与压辊接触并由压辊定位的多孔载体的内周。 因此，油墨辊和墨桶的内周因此可以在均匀的压力下相互接触，而不会使滚筒的刚度降低并且没有任何晃动。

摘要： In an image forming apparatus, a sheet stacking device for stacking sheets sequentially driven out of the apparatus body has a stack tray including a base, and a pair of side fences mounted on the base and each having an inclined portion. The side fences are moved to positions matching the width of sheets beforehand. When the sheet driven out of the apparatus body falls onto the base, the opposite widthwise edges of the sheet are reshaped in an inverted arch configuration by the inclined portions of the side fences. Hence, sheets sequentially stacked on the base have their opposite edges accurately aligned with each other.
