Abstract
A scan unit having an electromagnetic interference (EMI) noise blocking unit and usable with an image forming apparatus includes a document plate supporting a document, a reading module which is disposed under the document plate, performs a reciprocating motion, and includes an image sensor that reads an image of the document and generates an image signal in response to the read image, a flexible flat cable (FFC) which is connected to the reading module and functions as a transfer path of power and the image signal, and an EMI noise blocking unit which blocks noise that occurs when the image signal of the reading module is transmitted.
Claims15
An image forming apparatus comprising:
- a scan unit comprising:
- a document plate supporting a document,
- a reading module which is disposed under the document plate, performs a reciprocating motion, and includes an image sensor that reads an image of the original document and generates an image signal in response to the read image,
- a flexible flat cable (“FFC”) which is connected to the reading module and functions as a transfer path of power and of the image signal, and
- an electromagnetic interference (“EMI”) noise blocking unit located between a noise-generating portion of the reading module and the FFC to block noise that occurs when the image signal of the reading module is transmitted through the FFC;
- and
- a printing unit to print an image according to the image signal,
- wherein the EMI noise blocking unit is part of an FFC fixing unit which fixes the FFC to a side of the reading module to cause the FFC to run along the side of the reading module, and
- wherein the EMI noise blocking unit is located on an inside portion of the FFC fixing unit.
A scan unit comprising:
- a reading module having an image sensor to read an image of a document and to generate an image signal in response to the read image;
- a cable connected to the reading module to provide a transfer path of the image signal;
- and
- an EMI noise blocking unit disposed between a noise-generating portion of the reading module and the cable to block noise from the reading module,
- wherein:
- the cable comprises:
- a first portion electrically connected to the reading module to transmit the image signal,
- a second portion extended from the first portion and disposed to contact the side of the reading module, and
- a third portion extended from the second portion electrically connected to a controller to transmit the image signal;
- and
- the EMI noise blocking unit is disposed adjacent to the second portion.
A scan unit comprising:
- a reading module having an image sensor to generate an image signal;
- a power source to generate a power;
- a cable disposed between the reading module and the power source to provide a transfer path of an image signal of the reading module and a power of the power source;
- and
- an EMI noise blocking unit disposed on a first portion of the cable to block noise from the reading module, and disposed on a second portion of the cable to block noise from the power source,
- wherein:
- the cable comprises:
- a first portion electrically connected to the reading module to transmit the image signal,
- a second portion extended from the first portion and disposed to contact the side of the reading module, and
- a third portion extended from the second portion electrically connected to a controller to transmit the image signal;
- and
- the EMI noise blocking unit is disposed adjacent to the second portion.
