    Abstract: A separation roller is provided in a first end portion of a separation roller shaft through a torque limiter. The separation roller is provided to be able to come into pressure contact with a conveying roller rotatably supported by a conveying roller shaft. A support portion supports the separation roller in a cantilever condition and is formed to be elastically deformable. The support portion supports the separation roller shaft such that the separation roller shaft is inclined by a predetermined angle with respect to the conveying roller shaft such that the first end portion of the separation roller shaft is positioned upstream in a sheet conveying direction of a second end portion in a state in which the conveying roller is not driven.

    Abstract: An inverting roller device is used for changing a conveying path of a paper. The inverting roller device includes a first rotating shaft, a first roller, a second rotating shaft, a second roller, and a first swinging arm. The first roller and the second roller are disposed on the first rotating shaft and the second rotating shaft, respectively. The first swinging arm is pivotally disposed on the first rotating shaft and connected with the second rotating shaft. First, the first roller and the second roller are rotated to allow the paper to be moved in a first traveling direction. Then, the rotation of the first roller is temporarily stopped, and the second rotating shaft and the second roller are driven by the first swinging arm to be moved relative to a surface of the first roller. Consequently, the conveying path of the paper is changed.

    Abstract: Disclosed are a sheet feeding apparatus and an image forming apparatus capable of reliably separating and feeding sheets one by one without delay and damage to a sheet for a high speed of a printer or the like. A sheet feeding portion has a nip guide member having a sloped guide surface sloped so as to guide a leading end of a sheet to a separation nip portion such that a guide leading-end is biased to a feed roller with a predetermined distance from the feed roller. A support member supports the nip guide member not to recede from the feed roller when a thickness of a sheet bundle bumping into the sloped guide surface is smaller than a predetermined distance between the feed roller and the guide leading-end and supports the nip guide member to recede from the feed roller when the thickness is larger than the predetermined distance.
