| description | To enable illumination in a wide range by diffuse illumination while minimizing a housing and enable even a workpiece that is difficult to be read with diffuse illumination to be read to expand a corresponding range to various workpieces.SOLUTION: A fixation-type optical information reading apparatus 1A comprises: a translucent plate 52 which is provided on the front side of a first illumination group 4a; a diffuser plate 51 which is provided on the front side of a second illumination group 4b and has a larger area than the translucent plate 52; and decoding means which decodes a code image acquired by a camera by irradiating a code with light from the first illumination group 4a via the translucent plate 52 and a code image acquired by the camera by irradiating the code with light from the second illumination group 4b via the diffuser plate 51.SELECTED DRAWING: Figure 3
【課題】筐体を小型化しながら、拡散照明による広範囲の照明を可能にし、しかも、拡散照明では読取が困難なワークであっても読取可能にして様々なワークへの対応範囲を拡大させる。【解決手段】固定式の光学情報読取装置１Ａは、第１の照明グループ４ａの前方に設けられる透光板５２と、第２の照明グループ４ｂの前方に設けられ、透光板５２よりも面積の大きい拡散板５１と、第１の照明グループ４ａからの光を透光板５２を介してコードに照射しカメラで取得したコード画像と、第２の照明グループ４ｂからの光を拡散板５１を介してコードに照射しカメラで取得したコード画像とをデコードするデコード手段と、を備えている。【選択図】図３ |
