Abstract
A device for preventing movement of an original document on the platen of a copier where the platen reciprocates is disclosed having a protrusion that is adapted to adhere to the platen cover. The protrusion is locatable according to the size of the original document being copied and applies pressure in a concentrated area on the platen or the document to prevent movement of the original document while being copied.
Claims1
An electrostatic copying apparatus including a reciprocating platen and a means for facilitating removal of a document from said platen without creating a vacuum hold on said document, said facilitating means comprising:
- a. a platen cover, and
- b. space creating means detachably secured to said cover and adapted when said cover is closed to allow through-flow of air over said document on said platen whereby the vacuum associated with the lifting of the platen cover away from the documents is substantially reduced.
