IMAGE FORMING APPARATUS

摘要

An image forming apparatus which suppresses the degradation of an image signal originating in ESD with a simple configuration is provided. An original feeder unit is supported openably and closably by a hinge mechanism fixed on a bottom member of an image reading unit. An image sensor substrate of an image reading unit and an image processing substrate of an image forming unit are connected by a cable. An electrically conductive connecting portion electrically connects a bottom member of the image reading unit with a casing of the image forming unit, and is arranged along the cable. The bottom member has a notch formed therein, the connecting portion is fixed to the bottom member so as to extend over the notch, and the cable is arranged so as to pass through an opening portion thereby formed in a direction from above to below of the bottom member.

主权项

1. An image forming apparatus comprising:
an electrically conductive member; a platen disposed above the electrically conductive member; an image reading unit, disposed between the electrically conductive member and the platen, and having an image reading portion configured to scan an original placed on the platen, for reading out an original image; an image forming unit comprising
an electrically conductive casing,an image processing portion connected to the image reading portion by a cable, to receive an image signal from the image reading portion by the cable and to process the image signal, andan image forming portion disposed inside of the electrically conductive casing, and forming an image, based on a result of the image processing by the image processing portion; an opening and closing member configured to open and close a surface of the platen; an electrically conductive hinge member fixed to the electrically conductive member, and being able to open and close the opening and closing member; and an electrically conductive connecting portion for an electrical continuity from the electrically conductive member to the electrically conductive casing, wherein the cable is passes through a first opening portion surrounded by the electrically conductive connecting portion and the electrically conductive member.
