Patent number: 8558956Abstract: An image display system comprises red, green and blue laser light sources, a spatial light modulator that modulates the laser light of different colors in a time sharing manner and a controller that controls the operation of the laser light sources and the spatial light modulator. The green and red laser light sources are lit in this order in each frame. The green color is diminished due to the response delay of the spatial light modulator, but the green laser light produced by the green laser light source has a relatively large color phase shift from the standard green color so that the shortage of green color cancels the color phase shift of the generated green color so that the color phase shift of the displayed intermediate color can be minimized.Type: GrantFiled: December 30, 2011Date of Patent: October 15, 2013Assignee: Panasonic CorporationInventors: Yoshihiro Teshima, Yoshitaka Kitaoka, Takayuki Ooie, Tetsuro Mizushima

Patent number: 7535610Abstract: A light source apparatus includes a light source unit in which a light source and a light source supporting member having elasticity in an optical axis direction are coupled together, and a collimating lens base member on which a collimating lens is supported. An optical axis direction adjusting member is positioned between the light source unit and the collimating lens base member. A position of the light source unit can be adjusted within a plane approximately perpendicular to the optical axis, and the light source unit can thereafter be secured relative to the collimating lens base member via the light source supporting member. The optical axis direction adjusting member is movable in the optical axis direction, and is disposed such that by its movement it causes the light source supporting member to deform against the elasticity of the light source supporting member, thereby allowing an adjustment of a position of the light source with respect to the collimating lens in the optical axis direction.Type: GrantFiled: October 12, 2006Date of Patent: May 19, 2009Assignee: Panasonic CorporationInventors: Yoshitaka Kitaoka, Atsushi Sogami

Publication number: 20060285901Abstract: An image forming apparatus that enables a document ejected after image information reading is finished, and a printed sheet on which an image has been formed based on this image information, to be removed easily while the distinction between the two is clearly maintained. According to an image forming apparatus (100) of the present invention, a sheet document S whose image information has been read is ejected onto a document ejection tray (145), and a sheet Ps on which image information has been recorded is ejected onto a sheet ejection tray (151), so as to be crosswise to each other. By this means, even though sheet document S and printed sheet Ps are removed in a mutually overlapping state, sheet document S and printed sheet Ps can be distinguished from each other since their directions of ejection are crosswise to each other.Type: ApplicationFiled: June 9, 2006Publication date: December 21, 2006Applicant: MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD.Inventors: Masao OOTSUKA, Noriyuki TAJIMA, Yoshitaka KITAOKA

Publication number: 20050231772Abstract: An image forming apparatus that enables a source document ejected after image information reading is completed, and a printed sheet on which an image has been formed based on the image information, to be removed easily with one hand while maintaining their segregated state. In this apparatus, a source document feed tray holds a source document. A source document ejection tray is positioned below source document feed tray, and holds an ejected source document. A sheet ejection tray is positioned above source document feed tray, and holds a printed sheet ejected onto the uppermost part of the main body of the apparatus. Source document ejection rollers eject a source document into source document ejection tray so that the ejection direction downstream edge of source document ejected into source document ejection tray faces the ejection direction downstream-side position of source document ejection tray rather than the source document feeding direction upstream edge of source document feed tray.Type: ApplicationFiled: April 7, 2005Publication date: October 20, 2005Applicant: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshitaka Kitaoka, Noriyuki Tajima, Atsushi Sogami, Hiroshi Terada, Yuzo Kawano
