Description
しかし、前述の特許文献1記載の構成では、やはり原稿の画像を読み取り時には、コンタクトガラスに蜜着しながら読取手段を移動させているので、上述した問題は半減されるが、根本的には解消し得ない、などといった課題がある。
ベース片311にシャーシー32を取り付けて前記ガイドシャフト4を跨ぐように設け、その後下側のベース片312を図示しないボルトなどの結合部品を用いて固定するように形成すると、前記読取手段3のガイドシャフト4への装着や寸法調整を簡単に行うことができるので、好ましい。

Claims (3)
- 原稿を載置するコンタクトガラスを有する原稿載置台と、筐体内に収納され前記コンタクトガラス上に位置決めされた前記原稿を読取る密着型イメージセンサーからなる読取手段と、前記筐体内に配設され、前記読取手段の移動を案内するガイドシャフトとを備えた原稿読取装置において、
前記読取手段を、前記ガイドシャフトに装着されるベースに取付けられたシャーシーと、このシャーシー内に配置され、その上部が位置決めストッパーを介してシャーシーの基準面に接し、その下部に設けられた圧縮バネにより上方に押し圧された密着型イメージセンサーとから形成し、前記ガイドシャフトを原稿の読取面から一定寸法に保持し、かつ前記ガイドシャフトからシャーシーの基準面の寸法を、前記原稿に対して密着型イメージセンサーの焦点距離が最適となるように設定し、前記読取手段を前記コンタクトガラスから離間し、非接触状態でホームポジションから読取最終位置に読取走査するとともに、読取最終位置からホームポジションにそれぞれ移動し得るように形成したことを特徴とする原稿読取装置。 - 前記読取手段のベースの貫通孔内面と、シャフトとの接触が、断面視で3点接触であることを特徴とする請求項1に記載の原稿読取装置。
- 前記読取手段のベースを、前記シャフトを跨ぐような分割構造に形成したことを特徴とする請求項1または請求項2に記載の原稿読取装置。
