Filed: 2002-09-30
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the influence of noise when a facsimile machine is used by enabling the facsimile machine to be attached to an image forming apparatus without increasing the apparatus body.  <P>SOLUTION: The facsimile machine 40 for transmitting and receiving information of facsimile communication can be detachably attached on the external surface of the apparatus body 2 so as to be close to an image processing unit in the apparatus body 2, and the facsimile machine 40 is electrically connected to the image processing unit via a signal line with the facsimile machine 40 attached on the external surface of the apparatus body 2. With this constitution, since the signal line between the image signal processing unit and the facsimile machine 40 is reduced in length, the facsimile machine 40 hardly receives the influence of noise generated in the apparatus main body 2, and transmits and receives image information stably. Further, since the facsimile machine 40 is detachably attached on the apparatus body 2, the installation space of the apparatus body 2 is suppressed when the facsimile machine 40 is not attached.  <P>COPYRIGHT: (C)2004,JPO
