Abstract
Official abstract text for this publication.
Provided is a line illuminating device including: a light-emitting unit including a light-emitting-unit housing and a light emitter that emits light; a light guide including a light-guide body formed in a rod shape and a light-guide flange provided at a first end portion of the light-guide body; and a case including a case body formed in a rod shape, the case body being partially open when viewed in a longitudinal direction of the case body, the case body housing the light-guide body inside, in which the light-guide flange is interposed between a first end in the longitudinal direction of the case body and the light-emitting-unit housing, and a space is formed between an end of the light-guide body and the light emitter.
First claim
Opening claim text (preview).
What is claimed is: 1. A line illuminating device comprising: a light-emitting unit including a light-emitting-unit housing and a light emitter that emits light; a light guide including a light-guide body formed in a rod shape and a light-guide flange provided at a first end portion that is one end portion in a longitudinal direction of the light-guide body; and a case including a case body formed in a rod shape, the case body being partially open when viewed in a longitudinal direction of the case body, the case body housing the light-guide body inside, wherein the light-guide flange is interposed between a first end in the longitudinal direction of the case body and the light-emitting-unit housing and contacts the case body and the light-emitting-unit housing so as to position the light guide-body with respect to the light emitter, and a space is formed between a first end in the longitudinal direction of the light-guide body and the light emitter. 2. The line illuminating device according to claim 1 , wherein the light-guide flange and the light-emitting-unit housing are provided with respective alignment portions, the alignment portion of the light-guide flange and the alignment portion of the light-emitting-unit housing engage with each other, and a center of a first end face in the longitudinal direction of the light-guide body and a center of the light emitter are identical to each other when viewed in the longitudinal direction of the light-guide body. 3. The line illuminating device according to claim 1 , wherein a truncated-cone lateral engagement face is provided on a first side that is one side in a thickness direction of the light-guide flange, a planar engagement face is provided on a second side that is another side in the thickness direction of the light-guide flange, the light-emitting-unit housing is provided with a truncated-cone lateral engagement face, the first end in the longitudinal direction of the case body is provided with a planar engagement face, the planar engagement face of the light-guide flange has surface contact with the planar engagement face of the case body, and the truncated-cone lateral engagement face of the light-guide flange has surface contact with the truncated-cone lateral engagement face of the light-emitting-unit housing.
