Description
まず、図3乃至図5を参照して、本実施例に係る光学的情報読取装置の全体構成について述べる。図3に示すように、光学的情報読取装置の本体ケース1は、丸みを帯びた薄型のほぼ矩形箱状をなす主部1aの下面側後部寄りに、ユーザが片手で把持して操作することが可能なグリップ部1bを一体的に有して構成されている。前記本体ケース1(主部1a)の先端面部には、矩形状をなし透光性を有する読取口1cが設けられている。また、前記グリップ部1bの上端部には、読取指示用のトリガスイッチ2が設けられている。
Claims (5)
- 読取口を有するケース内に、多数の画素を縦横方向に配列して構成されるエリアセンサを備え、一次元コード及び二次元コードの双方の読取りを可能とした光学的情報読取装置であって、
前記エリアセンサを、前記読取口の縦横方向に対して、斜め方向に傾けて配置すると共に、
前記エリアセンサの各画素の信号値を読出す走査方向が、該エリアセンサの実際の配置状態における水平方向とされていることを特徴とする光学的情報読取装置。 - 前記エリアセンサは、縦横方向に同数の画素を有して構成され、ほぼ45度の傾斜角度で配置されていることを特徴とする請求項1記載の光学的情報読取装置。
- 読取るべきコードが一次元コードである場合に、前記エリアセンサのうち、前記一次元コードの画像全体を横切るように画素が並ぶ複数の読取ラインを用いて読取り処理を行う
ことを特徴とする請求項1又は2記載の光学的情報読取装置。 - 前記読取り処理は、画素の配置がほぼ半ピッチずれている2本の読取ラインを用いて行われることを特徴とする請求項3記載の光学的情報読取装置。
- 前記読取り処理は、前記エリアセンサのほぼ中心に位置する読取ラインを用いて行われることを特徴とする請求項3又は4記載の光学的情報読取装置。
