  • Patent number: 8991822
    Abstract: A conveyor device includes a conveyor including a conveyor roller to convey a sheet along a conveyance path, a cover movable between a closed position where the cover covers the conveyor roller and an open position where the cover is separated from the conveyor roller. The conveyor further includes a pinch roller urged toward the conveyor roller when the cover is in the closed position. When the cover is in the closed position, the conveyor roller and the pinch roller define a nip point along the conveyance path. The conveyor device includes a holder supported by the cover and to rotatably support the pinch roller and an urging member disposed between the cover and the holder to move the holder away from the cover to urge the pinch roller toward the conveyor roller when the cover is in the closed position.

  • Patent number: 8964268
    Abstract: A sheet feeding device is formed with a sheet mounting part, and a sheet feeding unit defining a sheet feed path having inlet and outlet. The sheet feeding unit is configured to introduce the sheet on the sheet mounting surface from the inlet, feed the sheet along the feed path, and discharge the sheet from the outlet onto the sheet mounting part. The sheet mounting part includes first and second members arranged next to each other. The first and second members with a border therebetween define a sheet mounting surface. An end portion of one of the first and second members has one or more protruded portions, while an end portion of the other member has one or more slits configured to receive the one or more protruded portions. An upper surface of the one member is located at a higher position than the upper surface of the other member.
