Patent number: 7942561Abstract: A rod- or plate-shaped light guide includes a first end that receives illuminating light incident thereon, a bottom surface having a reflecting portion thereon for reflecting the light, an emitting face which emits the reflected light, and a protruding portion protruding longitudinally and continuously from the light guide at a second end thereof. The protruding portion has a reduced peripheral dimension compared to a peripheral dimension of an adjacent portion of the light guide, and a reflective body is provided on the protruding portion and covers a longitudinal end face of the protruding portion extending perpendicular to the emitting face. When viewed along an axial direction of the light guide, the reflective body does not jut out from an end face of the light guide even when the body wraps on to a side surface of the protruding portion or expansion occurs.Type: GrantFiled: December 27, 2006Date of Patent: May 17, 2011Assignee: Nippon Sheet Glass Compny, LimitedInventors: Takeshi Ishimaru, Takashi Kishimoto, Hidemitsu Takeuchi, Tomihisa Saito, Hideki Azuma, Takahiro Hashimoto

Patent number: 7722223Abstract: A structure of a line lighting device permits a rod-like light guide to be attached to a case without rubbing against the case. An end portion of the rod-like light guide provided with a pin is inserted into an opening in a case main body and pushed down, thus making the pin engage with a recess in the case main body. At this time, a distal end of the rod-like light guide is inserted, to some extent, into an opening in a light emitting unit fixing portion. Subsequently, the rod-like light guide is pushed down and pivoted around the pin so as to be completely contained within the case main body. In this state, the distal end of the rod-like light guide is fitted into the opening and the end face of the rod-like light guide is flush with the outer side face of the light emitting unit fixing portion.Type: GrantFiled: December 22, 2006Date of Patent: May 25, 2010Assignee: Nippon Sheet Glass Company, LimitedInventors: Tomihisa Saito, Hidemitsu Takeuchi, Takeshi Ishimaru

Publication number: 20090003016Abstract: To provide a rod-like light guide and a line lighting device including the rod-like light guide, both of which are easy to include in an image reading device, a contact-type image sensor and an image reading device. For instance, a protruding portion having a flat or curved surface is formed by grinding an end face of a rod-like light guide in a longitudinal direction while leaving at least 80% of the surface area of the end face, and a reflective surface is formed by bonding a heat transfer film to the protruding portion. Thus, even if a portion of the protrusion portion melts when performing thermal processing on the heat transfer film, the portion will not jut out beyond a cross-sectional area of the rod-like light guide, and the rod-like light guide can be easily contained in a case.Type: ApplicationFiled: December 27, 2006Publication date: January 1, 2009Applicant: Nippon Sheet Glass Company, LimitedInventors: Takeshi Ishimaru, Takashi Kishimoto, Hidemitsu Takeuchi, Tomihisa Saito, Hideki Azuma, Takahiro Hashimoto
