Publication number: 20120013680Abstract: At a front-end side opposite to a head-fixing-member-attachment side, a protection member has an inclined plane sloped up from a head side toward the opposite outer side in a direction in which liquid ejecting heads are arranged in a row. The surface of the front end is located at a position that is not closer to a head-fixing member in comparison with the nozzle surface of each of the liquid ejecting heads attached to the head-fixing member or level therewith. A recess is formed at a part of the inclined plane. In a state in which one of the caps faces the protection member and, in addition, each of the remaining caps is in contact with the nozzle surface of the liquid ejecting head, a part of the cap facing the protection member is in the recess, which ensures that the cap is not in contact with the protection member.Type: ApplicationFiled: July 7, 2011Publication date: January 19, 2012Applicant: SEIKO EPSON CORPORATIONInventors: Kenichi Kitamura, Yasushi Yajima, Norihito Harada, Daisuke Hiruma, Ryo Hamano, Hiroyuki Hagiwara

Publication number: 20090144291Abstract: There is provided a technique capable of executing a predetermined processing while continuing a database processing. Firstly, the database to be operated is switched from the main database to a duplicate database. The predetermined processing is executed to the main database which becomes the non-operation mode by the switching. Next, a database access request is distributed to the duplicate database which becomes the operation mode by the switching, thereby performing the database processing. Update information indicating the content of the update processing performed to the duplicate database is output. The output update information is reflected on the main data base for which the predetermined processing has been executed. After this, the database to be operated is switched from the duplicate database to the main database.Type: ApplicationFiled: January 30, 2009Publication date: June 4, 2009Inventors: Kenichi Kitamura, Mitsuo Miyazaki, Kota Yamaguchi, Hiroshi Yamakawa
