  • Patent number: 10728407
    Abstract: An image reader includes: a document transport path through which a document to be read is transported; a transport roller that is provided on a lower side in the document transport path and is driven to apply a feed force to the document. The lower side of the document transport path upstream from the transport roller is at a position that is lower than a highest position of an outer circumferential surface of the transport roller and is formed on a lower guide surface guiding the document to the transport roller. A guiding unit is provided downstream from the lower guide surface and guides the document from the lower guide surface to a position on the outer circumferential surface of the transport roller, the position being higher than the lower guide surface.

  • Patent number: 10594881
    Abstract: An image reader includes: a document transport path that is extended along a horizontal direction when the reader has a first posture and that transports the document; a transport roller that transports the document in the document transport path; a rotation-contact member document path rotating to have a posture in which a contact portion that comes into contact with the document blocks the document transport path and a posture in which the contact portion opens the document transport path; path A rotation center of the rotation-contact member is positioned on an upper side of the document transport path in the first posture and the contact portion projects from the upper side toward a lower side of the document transport path. A center-of-gravity position of the rotation-contact member is on a lower side from the rotation center in the first posture.

  • Patent number: 9821969
    Abstract: A paper case includes a paper ejection opening, side walls, and a front wall. When the paper case is mounted on a paper stand, the paper ejection opening is positioned at a front end facing a downstream side. In addition, the side walls are positioned on a first side and a second side in a direction intersecting a transport route and each have a height relative to the paper stand greater than a height of the paper feed opening relative to the paper stand. Furthermore, the front wall continues from the front end and slopes so that a height of the front wall relative to the paper stand increases toward an upstream side of the transport route.
