Abstract
Description
画像形成動作に関する情報を取得するユニットと、ユニットに設けられたユニット基板と、ユニット基板に接続される配線と、配線で第1の基板と接続され、ユニットを制御する制御基板と、を備えた画像形成装置であって、ユニット基板は、配線が接続されるコネクタを有し、コネクタの長手方向は、ユニット基板の短手方向の長さに比べて長く、ユニット基板の短手方向と交差するように設けられていることを特徴とする。
図1を参照し、画像形成装置の全体構成について概要説明する。図1は、本発明の実施例に係る画像形成装置の一態様であるカラーレーザープリンタ100の全体構成を示す縦断面図である。なお、画像形成装置としては、カラーレーザープリンタの他、複写機やファクシミリ等が挙げられる。
以下、露光装置3について説明する。図1(a)は、実施例1に係る露光装置3(ユニット)の斜視図であり、図1(b)はレーザ駆動基板45(ユニット基板)を正面から見た拡大図である。図1において、露光装置3の光学箱(筐体)40の内部構造の説明のために、カバー部材を取り外している。図2は、装置本体2のフレームと露光装置3の位置関係を表す図である。なお図2では、鉛直方向をH、水平方向において、左右方向をW、奥行き方向をDとしている。
実施例1では、露光装置3の小型化を図るため、露光装置3のレーザ駆動基板45に設けられたコネクタ46を、レーザ駆動基板45の長手方向に対してコネクタ46の長手方向が交差するように配置して構成としている。しかしながら本発明は、画像形成装置の内部に設けられたユニットを小型化するために用いることができ、適用範囲は露光装置3のレーザ駆動基板45に限らない。そこで本実施例では、本発明を画像形成装置100のセンサユニット23(ユニット)に適用した例について説明を行う。なお、本実施例に係る構成について説明では、実施例1と同様の構成については、同じ符号を付し、説明を省略し、差異点を中心に説明を行う。
