Patent number: 9174467Abstract: 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.Type: GrantFiled: May 27, 2014Date of Patent: November 3, 2015Assignee: Seiko Epson CorporationInventor: Kazuyoshi Ohashi

Patent number: 8567901Abstract: 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.Type: GrantFiled: August 31, 2012Date of Patent: October 29, 2013Assignee: Seiko Epson CorporationInventors: Daisuke Tanaka, Takafumi Ogimura, Minoru Kishigami, Kazuyoshi Ohashi, Shota Mizuno
