Patent number: 10343412Abstract: The liquid container has a spacer member provided in the liquid storage portion. When three directions orthogonal to each other are assumed to be a D direction, a T direction, and a W direction, in the D direction, a direction from a liquid outlet portion toward the other edge portion of the bag is assumed to be a +D direction, and the opposite direction to the +D direction is assumed to be a ?D direction, and a direction in which the dimension of the outer shape of the liquid container is smallest is assumed to be the T direction, and the spacer member has, on the +D direction side, a face inclined such that the dimension in the T direction of the spacer member increases from the +D direction side toward the ?D direction side.Type: GrantFiled: October 12, 2017Date of Patent: July 9, 2019Assignee: Seiko Epson CorpoationInventors: Hiroyuki Kawate, Hiroyoshi Ozeki, Manabu Yamaguchi, Takumi Nagashima, Yoshiaki Shimizu

Patent number: 9039625Abstract: A head unit for an ultrasonic probe includes a connecting section, an element chip and a storing section. The connecting section is configured to electrically connect the head unit to a probe main body of the ultrasonic probe. The element chip includes an ultrasonic element array having a substrate defining a plurality of openings arranged in an array pattern and a plurality of ultrasonic transducer elements with each of the ultrasonic transducer elements being provided in each of the openings. The element chip is configured to be electrically connected to a processing device of the probe main body through the connecting section. The storing section is configured to store operation setting information of the processing device to be output to the processing device through the connecting section.Type: GrantFiled: February 22, 2013Date of Patent: May 26, 2015Assignee: Seiko Epson CorpoationInventor: Masaki Takahashi

Publication number: 20140376031Abstract: A control device suppresses modifying a program related to printer control when a connected printer is replaced with a printer having a different structure. A host computer has a print controller that can execute processes based on status data; a virtual second printing device that outputs response data when a control command output from the print controller is input; and a data processing unit that converts the input control command to a control command compatible with an inkjet printer and outputs to the inkjet printer when a control command output from the print controller is input, and when status data from the inkjet printer is input, converts the status data to data compatible with a thermal printer based on the structural differences between the inkjet printer and the thermal printer, and outputs to the print controller.Type: ApplicationFiled: June 20, 2014Publication date: December 25, 2014Applicant: Seiko Epson CorpoationInventor: Akio Takamoto

Publication number: 20110085145Abstract: A projector includes: first and second light blocking members adapted to partially block a light beam from a light source, and a drive section adapted to make the first and second light blocking members perform an opening and closing operation. When the corresponding first and second light blocking members are located at a maximum blocking state, with respect to an opening and closing direction of the first and second light blocking members perpendicular to a system optical axis, a first and second support sections support the first and second light blocking members at predetermined positions on the system optical axis side from intermediate positions corresponding to midpoints of areas between edge portions of the first and second light blocking members on the system optical axis side and parts, to which outer edges of the light beam to be blocked are input.Type: ApplicationFiled: October 8, 2010Publication date: April 14, 2011Applicant: Seiko Epson CorpoationInventor: Daisuke Hayashi

Patent number: 7293864Abstract: A liquid container includes a container body (2) formed with a liquid supply port (3), and a container-side fixing structure (7) which releasably regulates movement of the liquid container in an outward pulling direction in cooperation with apparatus-side fixing structure provided for the container mounting part in a state where the liquid container is mounted onto the container mounting part. The container-side fixing structure (7) has a guide groove (16) into which a fixing pin of the apparatus-side fixing structure can be inserted, and which guides the fixing pin in mounting and removal operations of the liquid container to and from the container mounting part. The guide groove (16) includes a fixing part (18) which engages the fixing pin to regulate the movement of the liquid container (1) in the pulling direction in the state where the liquid container is mounted to the container mounting part.Type: GrantFiled: August 6, 2004Date of Patent: November 13, 2007Assignee: Seiko Epson CorpoationInventors: Hitotoshi Kimura, Taku Ishizawa, Satoshi Shinada, Takeo Seino
