  • Patent number: 9969174
    Abstract: Provided is a liquid ejection device including a liquid container tray that can suppress change in orientation and position of a liquid container on a support surface due to the difference in size of the liquid container. The liquid ejection device includes: a casing including a guide wall: a liquid container tray configured to support a liquid container: and a recording head that ejects liquid supplied from the liquid container that is supported by the liquid container tray to a medium. The liquid container tray is configured to be inserted to or removed from a casing along the guide wall, and includes a support surface that supports the liquid container and a movable wall configured to move in at least one direction on the support surface.

  • Patent number: 6607322
    Abstract: A printer unit 20 has a base frame 24 and a moving frame 26 supported thereon for rotation relative thereto so that the upper part of the moving frame can be inclined to the front of an installation-type transaction device. The moving frame 26 is provided with a bearing member 40 that supports a shaft of the rolled paper, a print mechanism section 46, an edge of paper insertion slot 44 for introducing the rolled-paper end into the print section, and an edge of paper discharge port 50a. The bearing member 40 has a rolled-paper-shaft acceptance port 40b that is opened to the rear of the moving frame, and the edge of paper insertion slot 44 is oriented to the rear of the moving frame. At maintenance and inspection time, the moving frame 26 is inclined forward, whereby the shaft acceptance port 40b and the edge of paper insertion slot 44 are oriented to the worker.

  • Patent number: 6602008
    Abstract: A print-medium transport unit including discharge rollers, a paper guide, and a lock member. The discharge rollers transport post-printed paper toward an outlet and can hold the leading end of the paper. The paper guide is placed upstream from the discharge rollers, and guides the leading end of the paper into the discharge rollers. The paper guide is rotatably supported so that the upstream side thereof opens a transport path of the paper, whereby when the leading end of the paper is held by the discharge rollers, the transport path allows the paper to be curved like a loop. The lock member locks the rotation of the paper guide when the leading end of the paper is guided into the paper guide. When the leading end of the paper reaches a predetermined position, the locking of the lock member is released.
