Patent number: 8157461Abstract: A printer having one roller of a transportation roller pair attached to cover renders the mechanism pressing the transportation roller pair together and the damping mechanism used when opening the cover using few parts, compactly, and at low cost. A damper spring 27 prevents the cover unit 3 of the printer 1 from opening suddenly and forcefully. A roller support lever 38 having the first follower roller 33b disposed to the distal end thereof is attached rotatably and movably to the cover unit 3. The roller support lever 38 is urged by the damper spring 27, and the first follower roller 33b on the distal end thereof is pressed to the first transportation roller 33a on the printer frame 11 side. The damper spring 27 functions as the damping mechanism when the cover unit 3 opens, and as the pressure mechanism of the first transportation roller pair 33 when the cover unit 3 is closed.Type: GrantFiled: November 20, 2008Date of Patent: April 17, 2012Assignee: Seiko Epson CorporationInventors: Tetsugo Ishida, Masahiko Yamada, Rikuo Yamada

Publication number: 20120076267Abstract: Disclosed is a technique for correcting a pixel defect in the capture of two radiological images with parallax therebetween. Radiation beam is directly radiated to a radiation detector 15 in two radiographing directions, without passing through a subject, thereby acquiring two defect detecting radiological images. A pixel defect in each of the two defect detecting radiological images is detected in advance. A pixel position where the pixel defect occurs is stored in advance so as to be associated with each radiographing direction. Then, radiation beam is radiated to the subject from the two radiographing directions to acquire two radiological images for diagnosis. A target pixel which is disposed at the stored pixel position where the pixel defect occurs in each of the two radiological images for diagnosis is corrected.Type: ApplicationFiled: September 28, 2011Publication date: March 29, 2012Applicant: FUJIFILM CORPORATIONInventors: Takao KUWABARA, Wataru Ito, Masahiko Yamada, Yasunori Ohta, Takeshi Kamiya, Tetsuro Kusunoki

Publication number: 20110311292Abstract: A recording medium detection method uses transmission and reflection photosensors to correctly detect if a recording medium having labels affixed to a liner is in the transportation path. The label printer has a reflection photosensor and a transmission photosensor disposed to the transportation path at positions separated the distance between the labels. Labels on the recording medium can always be detected by either or both the reflection photosensor and the transmission photosensor. Because the reflection photosensor is downstream from the transmission photosensor, a situation in which a black mark is at the detection position of the reflection photosensor and reflection is not detected and only the liner is at the detection position of the transmission photosensor and transmission of the detection beam is detected is avoided. Detecting transmission without detecting reflection of the detection beam therefore only occurs when the recording medium is not in the transportation path.Type: ApplicationFiled: August 29, 2011Publication date: December 22, 2011Applicant: Seiko Epson CorporationInventor: Masahiko Yamada

Patent number: 8029083Abstract: A recording medium detection method uses transmission and reflection photosensors to correctly detect if a recording medium having labels affixed to a liner is in the transportation path. The label printer 1 has a reflection photosensor 26 and a transmission photosensor 27 disposed to the transportation path at positions separated the distance L0 between the labels 12c. Labels 12c on the recording medium 12a can always be detected by either or both the reflection photosensor 26 and the transmission photosensor 27. Because the reflection photosensor 26 is downstream from the transmission photosensor 27, a situation in which a black mark 12d is at the detection position of the reflection photosensor 26 and reflection is not detected and only the liner 12b is at the detection position of the transmission photosensor 27 and transmission of the detection beam is detected is avoided.Type: GrantFiled: October 10, 2008Date of Patent: October 4, 2011Assignee: Seiko Epson CorporationInventor: Masahiko Yamada
