消灯するようになされている。Further, the point illumination is turned off when the reading start switch 16 is pressed so as not to interfere with reading by the image sensor 12.
なお、この点照明を、イメージセンサ１２の読取ライン
から、少しずらすようにしてもよい。Note that this point illumination may be slightly shifted from the reading line of the image sensor 12.
以上に述べた実施例では、点照明を２つだけ設けたが、
これを４つ、あるいは６つ設け、２つずつを１組として
重複するようにしてもよい。In the embodiment described above, only two point lights were provided, but
Four or six of these may be provided, and each set of two may overlap.

複数の点照明のすべてが重複する位置、または２つの線
照明が重複する位置では、イメージセンサ１２と表示情
報との平行も、容易に合わせることができる。At a position where all of the plurality of point illuminations overlap or at a position where two line illuminations overlap, the image sensor 12 and the displayed information can be easily aligned in parallel.
また、２１１Ｉ以上の点照明で、読取可能な表示情報の
範囲をも指示するようにしてもよい。Further, the range of display information that can be read may be indicated using point illumination of 211I or more.
