<p>A light-sensitive device (1) produces an image of a document (10), which it converts into electrical signals for the purpose of reproducing or transmitting said image. To this end, the light-sensitive device (1) comprises a matrix (2) of light-sensitive dots (P1 to P9) connected to an addressing device (46, 42) and to a scanner (32). The light-sensitive device (1) also comprises a light-emitting optical pencil (15) which makes it possible to use a light-sensitive surface (5) of the matrix (2) as a writing surface which serves as a graphics board.</p> |
