A cartridge mountable on a liquid ejection device is provided. The liquid ejection device includes a mounting section, an air supplying portion including an air supplying passage, and a detection section configured to detect an error when a predetermined air pressure is not reached even if air is supplied from the air supplying portion. The cartridge includes a case including a communication portion and a first leakage limiting portion that limits leakage of air supplied from the air supplying portion into an atmosphere. The communication portion includes a second leakage limiting portion that limits leakage of the air supplied from the air supplying portion into the case through the communication portion.

Cartridge and liquid ejection system

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.

Liquid container tray and liquid ejection device

A printer unit has a base frame and a moving frame 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 is provided with a bearing member that supports a shaft of the rolled paper, a print mechanism section , an edge of paper insertion slot for introducing the rolled-paper end into the print section, and an edge of paper discharge port . The bearing member has a rolled-paper-shaft acceptance port that is opened to the rear of the moving frame, and the edge of paper insertion slot is oriented to the rear of the moving frame. At maintenance and inspection time, the moving frame is inclined forward, whereby the shaft acceptance port and the edge of paper insertion slot are oriented to the worker.

Printer unit for transaction device

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.
