Claims

[Scope of utility model registration request]

In a slit exposure type image forming apparatus that uses a rod-shaped exposure light source to visually confirm the image position of an original by scanning light that passes through the original, an original confirmation mode is set to a mode that confirms all image positions on the original. a setting means, a moving speed setting means capable of appropriately setting the moving speed of the scanning section that scans the light, and a drive controlling the driving of the scanning section based on the information from the above two settings of 1,000 steps. 1. A document position confirmation device for an image forming apparatus, comprising: a control means; and a drive means for driving a scanning section under control of the drive control means.
