Claims (1)
ズ系を介して感光体面上に等倍を含む拡大及び縮小され
た静電潜像を形成するもので、上記半速ミラーの走査領
域とレンズ系の移動領域とをオーバーラツプさせるよう
に構成した可変倍複写装置において、上記半速ミラーの
走査領域とレンズ系の移動領域とがオーバーラツプする
部分において半速ミラーが上記レンズ系と衝突するのを
防止すべくレンズ系の移動と同期して移動する支持枠に
半速ミラーのレンズ系に対する接近を検出７、 する
検知部材と、前記検知部材が半速ミラーの接近を検知し
たときレンズ系を速かに半速ミラーと同一進行方向に移

複写装置における半速ミラーの二重衝突防止機構。A full-speed mirror and a half-speed mirror scan the original, and an enlarged and reduced electrostatic latent image including the same magnification is formed on the photoreceptor surface via a lens system, and the scanning area of the half-speed mirror is In a variable magnification copying apparatus configured such that the scanning area of the half-speed mirror and the moving area of the lens system overlap, the half-speed mirror collides with the lens system in a portion where the scanning area of the half-speed mirror and the moving area of the lens system overlap. A support frame that moves in synchronization with the movement of the lens system is provided with a detection member for detecting the approach of the half-speed mirror to the lens system, and a detection member for detecting the approach of the half-speed mirror to the lens system. A double half-speed mirror in a variable magnification copying device, characterized in that it is provided with a stop member that quickly moves and retracts the half-speed mirror in the same traveling direction as the half-speed mirror and stops the half-speed mirror in front of a lens system. Anti-collision mechanism.
