Abstract: In an inkjet printer, a feeding side tension applying means is provided with a feeding side tension adjustment mechanism, which is structured of a feeding side ballast arm that is extended toward a winding side tension applying means and vertically swingable around a rotation shaft perpendicular to a feeding direction of a printing medium and a feeding side ballast member that is attached to a tip end of the feeding side ballast arm, and a winding side tension applying means is provided with a winding side tension adjustment mechanism which is structured of a winding side ballast arm that is extended toward the feeding side tension applying means and vertically swingable around a rotation shaft perpendicular to the feeding direction of the printing medium “M” and a winding side ballast member that is attached to a tip end of the winding side ballast arm.

Abstract: An inkjet printer includes a platen having a placing face, a printing device, and a printing medium feeding device. A guide is provided on a feeding-out side via which a printing medium is to be fed out from the platen. The guide has a guide face. A printing medium temperature raising device is to heat the guide face so as to raise a temperature of the printing medium placed on the guide face. A temperature raising preventing device is provided between the guide face of the guide and a portion of the placing face facing a printing target region. The temperature raising preventing device is configured to prevent an extended portion of the printing medium from being heated by the printing medium temperature raising device. The extended portion corresponds an area which is extended to the feeding-out side by a predetermined length from the printing target region.

Abstract: A medium transport apparatus includes a feeding roller configured to rotate around a rotational axis. A guide rail extends along the rotational axis. A slider is supported by the guide rail and movable along the rotational axis. A rotatable pinch roller is configured to clamp medium between the feeding roller and the pinch roller to move the medium. A lever is connected to the pinch roller and movable to change a clamping state with respect to the medium between the feeding roller and the pinch roller. An arm is connected to the slider and configured to take an engaging position where the arm moves the lever to change the clamping state when the slider moves along the rotational axis and a standby position where the arm is not engaged with the lever when the slider moves along the rotational axis.

Abstract: A printer-plotter includes a guide rail, a first head, a second head, a driving device, a first connecting mechanism and a second connecting mechanism. The guide rail extends in a longitudinal direction. The first head is supported by the guide rail and movable along the longitudinal direction. The second head is supported by the guide rail and movable independently of the first head along the longitudinal direction. The driving device includes a driving force transmitting member and a driving mechanism configured to move the driving force transmitting member. The first connecting mechanism is configured to detachably connect the first head to the driving force transmitting member. The second connecting mechanism is configured to detachably connect the second head to the driving force transmitting member.

Abstract: A printer-plotter includes first and second heads which are supported by a guide rail and are movable along a longitudinal direction of the guide rail, independently. A driving member is supported by the guide rail and configured to move along the longitudinal direction between the first head and the second head. A first connecting mechanism is configured to connect the first head to the driving member detachably. A second connecting mechanism is configured to connect the second head to the driving member detachably. The first head is connected to the driving member by the first connecting mechanism and the second head is separated from the driving member in order to make the first head operate. The second head is connected to the driving member by the second connecting mechanism and the first head is separated from the driving member in order to make the second head operate.
