Claims

[Scope of utility model registration request]

In a slit exposure type image forming apparatus that uses a bar-shaped exposure light source to visually confirm the image position of the original using light that passes through the original, document confirmation mode setting is used to set the mode to confirm the image position of the original. a reflecting member that reflects the light from the exposure light source and irradiates it onto the surface of the document, and whose setting position can be changed, and by moving the reflecting surface, the range of light irradiation can be changed to either narrow or narrow; a reflecting member drive control means for driving and controlling the reflecting member so as to move the position of the reflecting member to widen the irradiation range when the original checking mode is set by the original checking mode setting means; A document position confirmation device for an image forming apparatus, comprising: a reflecting member driving means for driving the reflecting member.
