て露光用の光を照射する露光ランプを、他側方に
、露光ランプの照射光の一部を反対方向から原稿
ガラスに照射させるように反射する反射鏡をそれ
ぞれ配設した走査装置を、前記原稿ガラスに対し
て前記露光ランプと反射鏡との対向方向に走査可
能に設けてある光学装置において、前記露光ラン
プの照射光を原稿ガラスに当らないように遮断す
る遮断姿勢に反射鏡を揺動可能に構成し、前記露
光スリツト部が画像先端位置または基準潜像形成
用パターンよりもホームポジシヨン側に位置する
とき、前記反射鏡を遮断姿勢に揺動させる切替機
構を設けてある光学装置。 On one side of the anti-light slit part, there is an exposure lamp that irradiates the original glass with exposure light, and on the other side, there is an exposure lamp that reflects a part of the irradiated light from the exposure lamp so that it irradiates the original glass from the opposite direction. In the optical device, a scanning device, each having a reflecting mirror arranged thereon, is provided so as to be able to scan the original glass in a direction opposite to the exposure lamp and the reflecting mirror. The reflecting mirror is configured to be able to swing into a blocking position in which the mirror is blocked so as not to cause any interference, and when the exposure slit portion is located closer to the home position than the image leading edge position or the reference latent image forming pattern, the reflecting mirror is placed in the blocking position. An optical device that is equipped with a switching mechanism that allows it to swing.
