    • PURPOSE: A sheet material feed apparatus and a recording apparatus are provided to prevent the simultaneous supply of plural sheet materials, to avoid the extension of the cost and the operating time and to easily prevent the entrance of the shear edge of the sheet material into a separating block without using a complex machinery or any control. CONSTITUTION: A sheet material feed apparatus comprises sheet material stacking devices(15,16,17), a feed roller(11), a drive source, a separation roller, a separation roller holder and return device(13). The sheet material stacking device stack sheet materials. The feed roller(11) feeds the sheet materials stacked on the sheet material stacking device. The drive source drives the feed roller. The separation roller is rotated according to the feed roller to separate a sheet material. The separation roller holder holds the separation roller rotatably and the separation roller holder is rotated to thereby move the separation roller to a position in contact with the feed roller and a position apart from the feed roller. The return device(13) return the sheet materials other than the sheet material separated by the separation roller to the sheet material stacking device and the return device is controlled by one-direction rotation for driving the feed roller of the drive source. Thereby, the overlapped supply is prevented without using a complex machinery and the stability of the separating efficiency is improved without extending the supplying time.
    • 目的:提供片材进给装置和记录装置以防止同时供应多个片材,以避免成本和操作时间的延长,并且容易地防止片材的剪切边缘进入 分离块而不使用复杂的机械或任何控制。 构成:片材输送装置包括片材堆叠装置(15,16,17),进给辊(11),驱动源,分离辊,分离辊保持器和返回装置(13)。 片材堆垛装置堆垛片材。 进料辊(11)供给堆叠在片材堆叠装置上的片材。 驱动源驱动进纸辊。 分离辊根据进给辊旋转以分离片材。 分离辊保持器可旋转地保持分离辊,并且分离辊保持器旋转,从而将分离辊移动到与进给辊接触的位置和与进给辊分离的位置。 返回装置(13)将由分离辊分离的片材以外的片材返回到片材堆叠装置,并且通过单向旋转来控制返回装置,以驱动驱动源的进给辊。 由此,不使用复杂的机械就能防止重叠的供给,并且在不延长供给时间的情况下提高分离效率的稳定性。

    • PURPOSE: A paper feeding apparatus and an image forming apparatus having the same are provided to control a knock-up plate and a retard roller to be lifted using cams connected to one driving shaft, thereby reducing space restrictions and cost, reliably picking up a paper, and stably forming the image. CONSTITUTION: A paper feeding apparatus includes a pick-up roller (121), a knock-up plate (111), a forward roller (123), a retard roller (130), a first control unit (151), and a second control unit. Recording media (P) are loaded on the knock-up plate. The knock-up plate is capable of moving to a pick-up position in which the recording media are in contact with the pick-up roller, and to a release position in which the recording media are separated from the pick-up roller. The forward roller transfers the recording media picked up by the pick-up roller. The retard roller is capable of moving to a contact position in which multiple transfers are prevented by applying a frictional force to the rear side of the recording medium which is transferred between the retard roller and the forward roller, and to a separation position in which the retard roller is separated from the forward roller. The first control unit moves the knock-up plate to the pick-up position and the release position. The second control unit moves the retard roller to the contact position and the separation position.
