GENERAL DESCRIPTION OF A FACSIMILE
The facsimile has a system control section comprising mainly a CPU, and
the reading section, recording section, modem and other mechanisms are
connected to its periphery.
The system control section comprises mainly a CPU, and has a ROM
(Read Only Memory) in which facsimile operations are programmed, and
memory area for storing image data and other data such as telephone num-
bers. The main functions of the system control section include scanning
control for accepting image data from the image sensor, drive control for
driving the motors and other moving parts, recording control for operating
the recording section, image data control for transmitting image data to the
modem and receiving image data, and modem control for operating the
modem in various other ways.
Let's take a look at the main mechanisms in a little more details.
