Abstract:
A first light source and a second light source are arranged so that a protrusion direction of a first terminal from a first supporting body and a protrusion direction of a second terminal from a second supporting body are different when viewed in the longitudinal direction of a light guide. The first light source and the second light source are arranged so as to reduce a protrusion direction of the first supporting body and the second supporting body in a predetermined direction from an area where the first light source and the second light source overlap when viewed in the longitudinal direction of the light guide.
Abstract:
A sensor substrate unit is formed by connecting edges of a plurality of sensor substrates in a longitudinal direction. Sensor chips at the edges are mounted beyond the edges. The edges include convex portions and convex portions for connecting the sensor substrates. Farthest tips of the sensor chips are positioned inside of farthest edges of the convex portions and inside of farthest edges of the convex portions in the longitudinal direction.

An electromagnetic wave detector is provided. The electromagnetic wave detector comprises: a base; a sensor element arranged on a principal surface of the base and configured to convert, into an electrical signal, light emitted from a scintillator which receives an electromagnetic wave; a lens portion arranged between the scintillator and the sensor element and configured to collect the light generated by the scintillator to the sensor element; a light transmissive portion arranged between the lens portion and the sensor element and configured to transmit the light generated by the scintillator; and a shielding portion including an inner wall located on a periphery of the sensor element and configured to shield the electromagnetic wave. The inner wall is arranged between the light transmissive portion and the principal surface.
Abstract:
A light emitting unit is provided. The light emitting unit comprises a substrate, a light emitting element placed on a first surface of the substrate, a front panel covering the first surface, and a back panel placed on a second surface of the substrate, which is opposite to the first surface. An opening for extracting light emitted by the light emitting element is formed in the front panel, and the opening is formed to overlap a part of a light emitting surface of the light emitting element. The back panel has a thermal conductivity higher than that of the front panel, and includes a projecting portion that projects toward the first surface. The projecting portion is in contact with at least one of the first surface, the light emitting element, or the front panel.
Abstract:
There is provided with a lighting apparatus. An elongated first light emission unit and an elongated second light emission unit each extend in a longer side direction and a shorter side direction. The first light emission unit and the second light emission unit have respective end portions in the longer side direction that are connected to each other via a restricting mechanism having a shape that restricts relative movement of the first and second light emission units in the shorter side direction.

Abstract:
An illumination apparatus has a first longitudinal light source section that includes a first substrate and a second substrate on which a plurality of light sources are arranged in a line in the longitudinal direction, and a second longitudinal light source section that includes a third substrate and a fourth substrate on which a plurality of light sources are arranged in a line in the longitudinal direction. The first longitudinal light source section and the second longitudinal light source section are arranged side by side in the short direction. The plurality of light sources on the first longitudinal light source section and the plurality of light sources on the second longitudinal light source section are displaced from each other in the longitudinal direction of the first longitudinal light source section and the second longitudinal light source section.
Abstract:
An image sensor unit includes: a light condenser that collects light from the reading target object; an image sensor that receives the collected light collected and converts it into an electric signal; a housing having an elongated shape housing the light condenser and image sensor; and an elongated rigid member provided on a side surface elongated in an elongated direction of the housing. The housing has a multiple positions for fixation on the side surface. The rigid member is fixed to the side surface of the housing at at least two positions. A warping amount adjusting part is provided between the positions at which the rigid member is fixed. The warping amount adjusting part is capable of holding warping amount in the direction of the optical axis of the light condenser of the housing by intervention of a warping amount adjusting member between the rigid member and the housing.
