A reading device and an image forming apparatus are provided. The reading device includes an image reading device configured to read an image on a recording medium being conveyed, a background device serving as a background image when the image is read by the image reading device, and a foreign-object detector configured to compare a first read image obtained as the background device is read by the image reading device with a second read image obtained as the background device and the recording medium are read by the image reading device to detect an attached foreign object. The image forming apparatus includes the reading device and an image forming device.

A three dimensional scanner assembly for producing a two dimensional print of a three dimensional object includes a scanning panel that is positioned on a copying machine. The scanning panel is comprised of a resiliently flexible material. In this way the scanning panel can conform to the curvature of a rounded or otherwise bulky object thereby facilitating the copying machine to scan a majority of an outer surface of the rounded or otherwise bulky object. Thus, the copying machine is facilitated to reproduce a two dimensional print of a three dimensional object in a single scan. A lid panel is positioned on a scanning lid of the copying machine and the lid panel is positioned on top of the object that is placed on the scanning panel.
