  • Patent number: 9174467
    Abstract: A printer includes a media stacking section, a print section, a pickup roller, a relay roller, a common actuator, a transport mechanism section and a control section. The control section is configured to control the common actuator based on a print job and displacement of the printing media. The control section is configured to stop transferring of driving force of the common actuator from the pickup roller to an nth printing medium after the pickup roller draws out the nth printing medium and the relay roller starts to send out the nth printing medium which is drawn out in a case where a print job, where printing is carried out on n of the printing media with a length in a transport direction shorter than a transport distance of the printing media from the pickup roller to the print section, is processed in the continuous transport mode.

  • Publication number: 20150183607
    Abstract: A recording apparatus includes a apparatus main body, and a unit body that forms a medium transportation path, and is configured to be attachable and detachable with respect to the apparatus main body. The unit body includes a feeding roller that transports a medium, and a driven transportation unit that transmits the drive force of the drive transportation unit to the feeding roller. The unit body is displaceable between a first position at which the driven transmission unit is connected to the drive transmission unit and a second position at which the driven transmission unit is separated from the drive transmission unit. When a user pulls out the medium, the unit body retained at the first position moves from the first position to the second position.

  • Patent number: 8662633
    Abstract: An ink jet printer includes a carriage configured to be movable supporting a recording head that can eject ink onto paper, a cam member adjusting the height position of the carriage to adjust the distance between the paper and the recording head, a cap member abutting the recording head along with a biasing force, and an engagement member placed to oppose the cap member with the carriage therebetween and pressing the carriage to the cap member side. The sum of the weight of the carriage itself and the pressing force with which the engagement member presses the carriage is equal to or greater than the biasing force acting on the carriage through the abutting of the cap member.

  • Patent number: 8567901
    Abstract: An ink jet printer includes a movable carriage supporting a recording head, a cam member adjusting the height position of the carriage to adjust the distance between the paper and the recording head, a cap member that can abut the recording head, and an engagement member that can engage with the carriage in a case where the carriage moves from a printing area to a head opposing position. The cam member adjusts the height position of the carriage when the distance between the paper and the recording head is between a first distance in which the carriage does not engage with the engagement member and a second distance in which the carriage engages with the engagement member. The carriage is decelerated while moving, and the deceleration timing is earlier for the second distance than for the first distance.
