| 摘要 | According to one embodiment, an image scanning apparatus includes a document table on which an original document is stacked; a substrate; plural first light emitting elements located on one surface of the substrate, the first light emitting elements each emitting light for irradiating the original document on the document table with direct light not reflected by a reflection member; and plural second light emitting elements located on the other surface of the substrate, the second light emitting elements each emitting light for irradiating the original document on the document table with indirect light reflected by the reflection member. The reflection member includes a first reflection member and a second reflection member, and the first reflection member and the second reflection member are located in positions opposed to each other across a reflection optical path of light reflected by the original document on the document table. | ||

| 主权项 | 1. An image scanning apparatus comprising: a document table on which an original document is stacked; a substrate; plural first light emitting elements located on one surface of the substrate, the first light emitting elements each emitting light for irradiating the original document on the document table with direct light not reflected by a reflection member; and plural second light emitting elements located on the other surface of the substrate, the second light emitting elements each emitting light for irradiating the original document on the document table with indirect light reflected by the reflection member, wherein an optical path of the direct light to the document table is shorter than an optical path of the indirect light to the document table, the reflection member includes a first reflection member and a second reflection member, and the first reflection member and the second reflection member are located in positions opposed to each other across a reflection optical path of light reflected by the original document on the document table. | ||
