Abstract: A resin composition for a light guide article-preform is described, which enables the formation of a foamed layer having a large light scattering effect on the surface of a shaped article by laser irradiation processing at low cost. More specifically, the present invention relates to: a resin composition for a light guide article-preform, which contains a resin having a mass average molecular weight of 60,000 to 150,000, and has a 30% thermal mass reduction temperature of 310° C. or lower and a difference between a 40% thermal mass reduction temperature and a 20% thermal mass reduction temperature of 7° C. or less when a thermal mass measurement is performed with starting from the state at 100° C. under air at a temperature rising rate of 5° C./min.

Abstract: There is provided an operation device including a main body that has a top surface on which an operation unit is provided, and an opening/closing member that is provided to be openable and closable with respect to the top surface of the main body, around a rotation axis positioned in an edge portion of a first side of the main body. When the opening/closing member is opened, the main body is pushed up by abutment of at least a part of the opening/closing member and a placement surface. A thickness of the main body is reduced from the first side toward a second side opposite to the first side.

Abstract: Disclosed is a plate-like light guide element (24) provided with a light incident surface, a light exit surface (242), and an underside surface (243) disposed on the opposite side of the light exit surface (242). A foamed surface layer (244) is formed on at least a part of at least either the light exit surface (242) or the underside surface (243). The foamed surface layer (244) contains air bubbles and has a recessed sectional surface including the normal direction of the light exit surface (242) or the underside surface (243). The light guide element (24) is produced by performing infrared laser etching for at least a part of at least one of the main surfaces of a plate-like light guide element material composed of an acryl resin plate produced by a continuous plate production method, to form the foamed surface layer (244).

Abstract: There is provided an electronic apparatus, including a first housing, a second housing which has a display section and a support member supporting the display section, and a housing connection section which rotatably connects the second housing with respect to the first housing. The support member includes a first support section connected to the housing connection section, a second support section which fixedly supports the display section, and a support connection section, positioned between the first support section and the second support section, which has a flexibility to rotatably connect the second support section with respect to the first support section.

Abstract: According to the present disclosure, there is provided an information processing apparatus, including a first housing, a second housing, having a display section which displays information, in which the display section is reversed between a first position and a second position, a connection section which rotatably connects the second housing with respect to the first housing, a posture detection section which detects any of the four postures of a first posture, a second posture, a third posture, and a fourth posture, and a display control section which controls a display state of the display section in accordance with a detection result of the posture detection section.
