  • Patent number: 10016994
    Abstract: A recording apparatus includes a carriage, a transport drive roller, and a plurality of gears. The carriage includes a recording head configured to record onto a medium. The carriage is configured to move in a movement region in a first direction and a second direction that is an opposite direction thereto. The transport drive roller is configured to transport the medium to a recording region in which the recording head performs recording. The plurality of gears are configured to transmit power of a motor to the transport drive roller. When the carriage is positioned at an end of the movement region in the second direction, at least a portion of one of the plurality of gears overlaps the carriage when viewed along a vertical direction that is parallel to a direction of gravity and overlaps the recording head when viewed along an axial direction of the transport drive roller.

  • Patent number: 9986116
    Abstract: An image scanning apparatus includes a document table that forms a document mounting surface, a cover body that covers and uncovers the document table, and a hinge mechanism which has an angle retainer that retains an opening angle of the cover body and which allows the cover body to be lifted up and down. The hinge mechanism includes a case that is inserted into an insertion portion provided in the document table so that the case is displaceable in lift up/down directions of the cover body. The case includes an arm portion which extends in a direction that includes a lift up/down direction component and which is elastically deformable in a direction that intersects the lift up/down directions. The arm portion elastically contacts a contact portion provided in the insertion portion so that the cover body is retained in position in the lift up/down directions.
