Description
【考案の詳細な説明】
本考案は文字等を光学的に読み取る装置に関するもので
、特にセンサヘッドが文字等を記載した張票の送り方向
と直交する方向に移動して読み取る装置に関する。[Detailed Description of the Invention] The present invention relates to an apparatus for optically reading characters, etc., and more particularly to an apparatus in which a sensor head moves in a direction perpendicular to the feeding direction of a board on which characters, etc. are written.
従来、上記のような光学式読取り装置では、空中の塵埃
や帳票から生ずる繊維屑などがセンサヘッドのレンズあ
るいはそのカバーガラスなどに付着して誤読や張票のリ
ジェクトを生ずることがあった。Conventionally, in optical reading devices such as those described above, dust in the air or fiber waste generated from forms may adhere to the lens of the sensor head or its cover glass, resulting in misreading or rejection of the forms.
本考案は光学式読取り装置における上記障害を除去せん
とするものである。The present invention seeks to eliminate the above-mentioned obstacles in optical reading devices.
第１図は本考案の一実施例を示すもので、１は図示せぬ
ホッパより送られてきた帳票で、この帳票１は矢印方向
に回転するリード・ドラム２に巻きつけられ、センサヘ
ッド３の前方に運ばれる。FIG. 1 shows an embodiment of the present invention, in which numeral 1 is a form sent from a hopper (not shown), this form 1 is wound around a lead drum 2 rotating in the direction of the arrow, and the sensor head carried in front of.
前記センサヘッド３はリード・ドラム２の軸と平行な方
向即ち帳票１の送り方向と直交する方向に移動しながら
、帳票１上の文字あるいはマークを読み取る。The sensor head 3 reads characters or marks on the form 1 while moving in a direction parallel to the axis of the lead drum 2, that is, in a direction perpendicular to the feeding direction of the form 1.
上記センサヘッド３は第２図に示すように読取り開始前
の状態においてはホーム・ポジションＨ−Ｐにあり、こ
のホーム・ポジションＨ−Ｐは帳票１の幅に応じた読取
り領域Ｐ□〜Ｐ２から外れた位置に設定している。As shown in FIG. 2, the sensor head 3 is at the home position H-P before reading starts, and this home position H-P is located between the reading areas P□ to P2 according to the width of the form 1. It is set in a different position.
したがって読取り動作時にはセンサヘッド３がホーム・
ポジションＨ−ＰかうＰ２まで移動し、再びホーム・ポ
ジションＨ−Ｐに戻る。Therefore, during the reading operation, the sensor head 3 is in the home position.
It moves from position H-P to P2 and returns to home position H-P again.
このように動作するセンサヘッド３の移動範囲内でかつ
帳票の読取り領域から外れた位置例えば第２図に示す位
置に、センサヘッド３のレンズ上面と接触するようにク
リーニングブラシ４を設ける。A cleaning brush 4 is provided in a position within the movement range of the sensor head 3 operating in this manner and out of the document reading area, for example, at a position shown in FIG. 2 so as to come into contact with the upper surface of the lens of the sensor head 3.
このクリーニングブラシ４によりセンサヘッド３がホー
ム・ポジションＨ−Ｐから右方向へ移動するとき、ある
いはホーム・ポジションＨ−Ｐに復帰するとき、該セン
サヘッド３のレンズが常に清掃されることになる。The lens of the sensor head 3 is constantly cleaned by the cleaning brush 4 when the sensor head 3 moves rightward from the home position HP or returns to the home position HP.
このためセンサヘッド３が帳票３を走査するときは常に
最適の状態で文字あるいはマークを読み取ることができ
、誤読や張票のリジェクトをなくす効果がある。Therefore, when the sensor head 3 scans the form 3, it can always read characters or marks in an optimal state, which has the effect of eliminating misreading and rejection of the form.
また上記クリーニングブラシ４をホーム・ポジションＨ
−Ｐ上に設け、センサヘッド３がホーム・ポジションＨ
−Ｐに来たとき、該クリーニングブラシを回転あるいは
左右に移動してセンサヘッド３のレンズを清掃するよう
にしてもよい。Also, move the cleaning brush 4 to the home position H.
-P, and the sensor head 3 is in the home position H.
-P, the cleaning brush may be rotated or moved left and right to clean the lens of the sensor head 3.
