Facsimile Drum

A Facsimile Drum is a component of Teletype and Facsimile Equipment, which falls under the supply class of Communication, Detection, and Coherent Radiation Equipment.

The Facsimile Drum is a cylindrical drum that is used in facsimile machines to reproduce images or documents. It is typically made of a durable material, such as metal or plastic, and is coated with a photosensitive material.

When a document or image is scanned, the Facsimile Drum rotates and the photosensitive coating on the drum is exposed to light. The light causes the photosensitive material to react, creating an electrical signal that represents the scanned image. This signal is then transmitted or processed to produce a printed copy or a digital image.

The Facsimile Drum is an essential component of facsimile machines, as it is responsible for capturing and reproducing the visual information. It plays a crucial role in the transmission and reception of documents and images over long distances, making it a vital tool in communication and information exchange.
