Description
図1は、この発明の実施形態に係る画像形成装置1の概略構成図を示す。以下の説明において、前側、後側は、画像形成装置1の前側、後側(図1の紙面垂直方向の手前側、奥側)を意味し、左側、右側は、画像形成装置1を前側から見たときの左側、右側を意味するものとする。
上記2つの光走査装置4は左右方向に並んで配置されている。左側の光走査装置4は、マゼンタ(M)及びシアン(C)に対応するレーザー光を出射し、右側の光走査装置4は、イエロー(Y)及びブラック(K)に対応するレーザー光を出射するように構成されている。2つの光走査装置4の構成は同じであるため、以下では、右側の光走査装置4の構成についてのみ説明し、左側の光走査装置4の説明は省略する。
上記の実施形態では、移動機構63としてスクリュー軸64を有するスクリュー機構を採用したが、ワイヤー機構により保持部材62をガラスカバー43に沿って前後方向に往復移動させるような移動機構63にしてもよい。例えば、図18に示すように、4つのプーリー80にワイヤー81を矩形環状に巻き掛け、ワイヤー81の前後方向に延びる2つの辺部に保持部材62をそれぞれ固定し、2つの保持部材62を互いに前後逆向きに移動させる。
上記の実施形態では、内側ボス部材62a及び外側ボス部材62dが軸受プレート47に当接した際、前側バネ部70a又は後側バネ部70bの圧縮力で内側ボス部材62aが僅かに後側又は後側に押し戻され、内側ボス部材62aのネジ山62gがスクリュー軸64のネジ山64aに噛み合い、その後は内側ボス部材62a及び外側ボス部材62dが一体となって移動するようにしたが、内側ボス部材62aのネジ山62gがスクリュー軸64のネジ山64aに噛み合った後に、図19に示すように、内側ボス部材62aが外側ボス部材62dの開口部62eの前後長さの範囲内で移動するようにしてもよい。
