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:
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.
Abstract:
A sensor substrate (13) includes an insertion opening (131) for inserting a light source substrate (32), and a plurality of pads (111) that are arranged along the insertion opening (131). The plurality of pads (111) and an external connection terminal are connected through a solder, and a tip of the pads (111) reaches an opening edge of the insertion opening (131).
Abstract:
An image sensor unit includes: a plurality of light sources each including an LED chip; a plurality of light guides that are arranged in parallel to face incident surfaces on one side in a longitudinal direction for each of the plurality of light sources and that guide light from the plurality of light sources to a bill; an image sensor that converts light from the bill to an electric signal; a sensor substrate for mounting the image sensor; and a circuit board that is provided with the plurality of light sources on a same mounting surface and that is arranged on the sensor substrate on one side in the longitudinal direction of the plurality of light guides, wherein the sensor substrate includes a connection hole on one side in the longitudinal direction of the sensor substrate, and the circuit board is connected to the sensor substrate by connecting a connecting portion including a plurality of external connection pads to the connection hole.
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:
In an image sensor unit, a frame includes a light blocking portion that protrudes toward one surface of a circuit board at a position between a light source and an image sensor. On the one surface of the circuit board, a conductive portion that continuously overlaps with external lines of the light blocking portion in a sub-scan direction in a view of the circuit board in a direction orthogonal to the one surface is formed.
Abstract:
A plurality of edges of sensor substrates are connected in a longitudinal direction in a sensor substrate unit. Farthest tips of sensor chips at the edges of the sensor substrates are positioned inside of farthest edges of the edges in the longitudinal direction. The edges of the connected sensor substrates overlap each other in a thickness direction of the sensor substrates in plan view.
