Abstract

In an image reading apparatus, cables may be used to connect reading units (e.g., scanning devices) to a controller or control circuit board configured to execute certain instructions and perform various functions. The cables may be routed between the reading units and the controller so as to reduce and/or eliminate noise. For example, the cables may be routed through contact prevention devices that may include ferrite cores. The cables may also be routed in a manner so as to maintain a predefined distance therebetween and to minimize interference. For example, the cables may extend downward from a corresponding reading portion, change course to a horizontal direction parallel to the rotation axis of an openable unit of the image reading apparatus and such that the cable extends toward the controller, and subsequently extend downward such that the flexible flat cable is insertable into a corresponding connector of the controller.

Claims8

Dependent claims

An image reading apparatus comprising:

a main unit including:
a control circuit board configured to perform controls;
and
a contact prevention mechanism;
an openable unit including:
a document tray on which a document is placed;
and
a feeder configured to feed the document placed on the document tray along a feed path;
a first reading portion configured to read an image of a document;
a second reading portion configured to read an image of a document;
a first flexible flat cable configured to transmit an output signal of the first reading portion to the control circuit board;
and
a second flexible flat cable configured to transmit an output signal of the second reading portion to the control circuit board,
wherein the control circuit board is configured to perform the controls based on the output signal of the first reading portion and the output signal of the second reading portion,
wherein the first reading portion is disposed in the openable unit,
wherein the first and second flexible flat cables each include an overlap section where the first and second flexible flat cables overlap each other in a direction of thickness of the first and second flexible flat cables, and
wherein the contact prevention mechanism is configured to prevent the first and second flexible flat cables from contacting each other in the overlap section.
