An image forming device such as a copying machine provides a linearly polarized beam of light to be made incident on a document to be scanned which is placed on a document table. A transparent cover with a polarization filter attached to it covers the document such that the user can ascertain, without too much light entering his eyes, whether the document is placed at a correct position on the table.

An improved shredder has a closing device stored inside of its housing or inside a door. As the door is opened to pull out a bag filled with shredded paper, the bag closing device automatically protrudes and the operator has only to grab the top parts of the bag and press them through a groove made in the bag closing device and an adhesive tape wraps around the bag to close it.
