ブック原稿読取り装置

Abstract

(57)【要約】 【目的】 ブック原稿の読取り装置において、白基準に 汚れ等が付着しにくく、また付着した汚れ等を自動的に 運転中に取り除くことができるようにする。 【構成】 スキャナー部2が白基準板1に接近していな い状態で、白基準板1は自重により垂直に垂れ下がり、 白基準面が横向きとなって汚れにくく、異物も付着しに くい。スキャナー部2が接近すると、白基準面の読み取 りを行う前にスキャナー部2の先端が弾性体4に接触し て走行方向へ回転させ、これに伴って白基準板1も回転 して白基準面が上向きになり、スキャナー部2が画像読 み取りの白基準を読み取れるようになる。スキャナー部 2が離れると、弾性体4が元の位置へ回動復帰し、白基 準板1は弾性体4の回動力と自重で汚れ等が付着しにく い垂直状態へ戻る。
PURPOSE: To allow dirt or the like to be hardly sticked to a white reference board and to eliminate the sticked dirt or the like automatically in operation in the reader for a book original. CONSTITUTION: When a scanner section 2 is not close to a white reference board 1, the white reference board 1 is pendant vertically by its self weight and the white reference face is directed laterally so that the face hardly takes dirt and a foreign material is hardly sticked thereon. When the scanner section 2 approaches the board, a tip of the scanner section 2 is in contact with an elastic body 4 to turn the elastic body in the running direction before the white reference face is read, then the white reference board 1 is also turned and the white reference board 1 is directed upward so as to allow the scanner section 2 to read the read white reference. When the scanner section 2 leaves from the elastic body 4, the elastic body 4 is turned and restores to the home position, and the white reference board 1 returns to the vertical state with a turning force of the elastic body 4 and the self-weight where dirt or the like is not easily sticked.
