Abstract
Abstract An electrostatic copying machine system including a copying machine and a plurality of attachments therefor to enable the machine to make copies of different types of originals. The attachments include a letter copying bridge for making copies of sheet documents, a book platen for making copies of a page of a book or some other bulky article, and a microfilm scanner for making copies of a microfilm original. At the top of the basic machine there are a plurality of rollers. Each of the attachments is driven by at least one of the machine rollers, so that the original to be copied can be scanned in synchronism with the machine operation. The electrical circuit of the basic machine includes a plurality of terminals extended to respective pins in a connector at the top of the machine. Each of the attachments includes a mating electrical connector which changes the overall circuit of the machine. In this manner, each attachment causes the machine operation to be changed to meet the specific needs of the particular type of original to be copied.
