  • Patent number: 8690142
    Abstract: A post-processing device includes an introductory conveying path, a processing tray, a paper receiving tray, an upper paper discharge roller, a lower paper discharge roller and a control section. The upper paper discharge roller and the lower paper discharge roller are disposed at an edge portion on the paper receiving tray's side of the processing tray. The upper paper discharge roller is capable of coming into contact with and away from the lower paper discharge roller. The control section causes the upper paper discharge roller to start a descending motion with a timing such that the upper paper discharge roller comes into contact with paper before the paper comes into contact with the paper receiving tray if the paper belongs to a second kind, where the paper of the second kind is lighter weight than that of a first kind.

  • Patent number: 7431287
    Abstract: The subject invention provides a sheet feeding device which can be easily attached to an image forming apparatus. The sheet feeding device includes an adapting part and a lock section. When the sheet feeding device is attached to the image forming apparatus, the adapting part is hooked to a catch section provided in the image forming apparatus. Then, the sheet feeding device is lifted up by the adapting part, which serves as a fulcrum, so as to attach lock section to an attachment board of the image forming apparatus. In this method, it is not necessary to lift up the entire body of the sheet feeding device, and therefore the sheet feeding device can be installed on the image forming apparatus with a little effort. After installation, the sheet feeding device transfers recording sheets to the image forming apparatus via a sheet feeding opening.
