摘要： A sheet member feeding and conveying apparatus has a tray having a tray main body capable of displacement in directions close to and away from a pickup section for taking out a document in the take-out position. There is a tray driving section for driving the tray main body to be displaced in the directions close to and away from the pickup section. A control section is provided for controlling the tray driving section so as to, in a feeding state, drive the tray main body to be displaced so that a document closest to the pickup section held on the tray is placed in the take-out position, and in a waiting state, drive the tray main body to be displaced in a waiting position closer to the pickup section than a position where the maximum holding amount of documents are held on the tray.

摘要： A paper feeder for use in copiers has a feed roller, a conveying roller and a registration roller. The apparatus further includes a feeding-conveying drive section for driving the conveying roller in synchronization with the rotation of the feed roller, and a conveying-registration drive section for driving the conveying roller in synchronization with the rotation of the registration roller. By this structure, the peripheral velocity of the rollers when the feed roller and conveying roller rotate can be set up higher than the peripheral velocity of the rollers when the registration roller and conveying roller rotate. An alternative construction of the apparatus includes a feeding-conveying drive section in which the conveying roller is driven through the conveying roller gear and conveying roller clutch and a conveying-registration drive section in which the conveying roller is driven through a pulley disposed on the rotary shaft of the registration roller, a timing belt and a clutch-equipped pulley disposed on the rotary shaft of the conveying roller. In this construction, the conveying roller is made to be able to be driven either by the feeding-conveying drive section or by the conveying-registration drive section.
摘要翻译：用于复印机的供纸器具有进给辊，输送辊和定位辊。该装置还包括与进给辊的旋转同步地驱动输送辊的进给传送驱动部分，以及用于与定位辊的旋转同步地驱动输送辊的输送对位驱动部。通过这种结构，当定位辊和输送辊旋转时，当进给辊和输送辊旋转时，辊的圆周速度可以设置得高于辊的圆周速度。该设备的另一种结构包括一个送料传送驱动部分，其中输送辊被驱动通过输送辊齿轮和输送辊离合器;以及一个输送对位驱动部分，其中输送辊通过设置在转动体上的皮带轮定位辊的轴，配置在输送辊的旋转轴上的同步带和配备有离合器的滑轮。在这种结构中，输送辊能够由输送驱动部或输送对位驱动部驱动。

摘要： A document feeder includes: a document detecting device arranged on the top of the copier body, for detecting a document inserted from the outside; a feed roller arranged adjacent to the document detecting device, on the top of the copier body, for feeding an inserted document into a space between the original table and the original cover, in response to the detection of a document by the document detecting device; and an original cover lifting device arranged on the top of the copier body, for lifting the original cover to create a gap between the original table and the original cover, in response to the detection of a document by the document detecting device. Alternatively, the feed roller further has a rotary cam on its shaft, so that the cam rotates to lift the original cover up as the feed roller rotates in the document feeding direction. Then, after the document is fed in place, the feed roller is reversely rotated in a constant time, whereby the document cover is sunk to press the document onto the original table.

摘要： A sheet feeding apparatus enables the uppermost sheet in sequence in a stack of recording papers be lifted by air flow to separate and to convey the recording paper. The feeding apparatus comprises a laying plate on which plural sheets are stacked, a sheet feeding means disposed above the stacked sheets, which means partially deforms the first sheet in sequence by negative pressure at the leading end part of the sheet, and air forming means which injects air flow between the first sheet and the next sheet near the both ends in the widthwise direction of the recording paper, which flow comprises a straightforward air flow, and an air flow directed outwardly in the widthwise direction. The recording paper is separated from the next sheet by the air flow.

摘要： When stacking up recording papers on a tray and conveying one by one from the top or bottom, they are conveyed by attracting in vacuum to a conveying belt. An example of conveying from the bottom is illustrated. When one recording paper is conveyed, its rear end comes into the attraction region of the conveying belt, and the second recording paper is attracted into the region out of the first recording paper in the attraction region, which results in duplicate feed. Therefore, the size of the attraction region is variable depending on the size of the recording paper so that the attraction region of the conveying belt may not come out from the rear end of the recording paper until the first recording paper is conveyed and its front end is held by the rear rollers of the conveying belt or the like.

摘要： A feeding device has a rotative threaded shaft and a rotatable paper tray. A movable joint is attached to the rotative threaded shaft, and permitted to move on the shaft. The movable joint is coupled to one corner of the rotatable paper tray. A shaft drive plate is secured to the movable joint. In the vicinity of the rotative threaded shaft, is disposed a shifting shaft extending in the direction of movable joint movements, which is permitted to freely move in the direction. An engaging member to be depressed by engaging the shaft drive plate and a spring to urge the shifting shaft to be located in a predetermined position, are attached to the shifting shaft. On the other hand, in the feeding device main body, there are installed an action plate for making a forward or backward movement in response to a movement of the shifting shaft driven by the shaft drive plate and switch for performing ON/OFF operation in response to shifting positions of the action plate. Thus, this arrangement makes it possible to reduce the number of required parts for connecting the feeding device to the feeding device main body and for detecting operating conditions of the rotatable paper tray.
摘要翻译：进给装置具有旋转螺纹轴和可旋转纸盘。可动接头连接在旋转螺纹轴上，允许在轴上移动。可移动接头联接到可旋转纸盘的一个角。轴驱动板固定在可动接头上。在旋转螺纹轴附近设置有沿可动接头运动方向延伸的变速轴，允许沿该方向自由移动。通过接合轴驱动板而被压下的接合构件和用于推动变速轴位于预定位置的弹簧被附接到变速轴。另一方面，在进给装置主体中，安装有用于响应于由轴驱动板驱动的换档轴的运动和用于响应地进行ON / OFF操作的开关而进行向前或向后运动的动作板以移动动作板的位置。因此，这种布置使得可以减少用于将馈送装置连接到馈送装置主体的所需部分的数量，并且用于检测可旋转纸盘的操作条件。
