Abstract
A scan unit includes a scan frame having a document tray to position a document thereon, a reading sensor movably disposed under the document tray to read the document, a bracket to support the reading sensor, a guide shaft to guide the movement of the reading sensor, and a ground unit to pass electromagnetic energy generated from the reading sensor to the scan frame. The ground unit electrically connects the bracket and the guide shaft.
Claims30
A scan unit, comprising:
- a scan frame including a document tray to position a document thereon;
- a reading sensor movably disposed under the document tray to read the document;
- a bracket to support the reading sensor;
- a guide shaft to guide the movement of the reading sensor;
- and
- a ground unit to electrically connect the bracket and the guide shaft.
A scan unit, comprising:
- an electrically grounded scan frame including a document tray to position a document thereon;
- a scanning sensor to move along a bottom portion of the document tray to scan the document;
- and
- a bracket to movably support the scanning sensor and electrically grounded to the scan frame to transfer any electromagnetic radiation received from the scanning sensor to the scan frame.
An image forming apparatus, comprising:
- a main body frame, which is grounded;
- a scanner, comprising:
- a document tray on which to place a document;
- a scanning sensor assembly movably disposed under the document tray and having a scanning sensor to read the document;
- an electromagnetic radiation carrying part to electrically connect the scanning sensor to the main body frame and pass at least a component of electromagnetic radiation generated by the scanning sensor to the grounded main body frame.
An image forming apparatus comprising a scan unit to read a document, an image forming unit to produce an image using information from the read document, and a main body frame to support the scan unit and the image forming unit, wherein the scan unit comprises:
- a document tray to position a document thereon;
- a reading sensor movably disposed under the document tray to read the document;
- a bracket to support the reading sensor;
- a guide shaft to guide the movement of the reading sensor;
- and
- a ground unit to electrically connect the bracket and the guide shaft.
An image forming apparatus comprising a scan unit to read a document, an image forming unit to produce an image using information from the read document, and a main body frame to support the scan unit and the image forming unit, wherein the scan unit comprises:
- a document tray to position a document thereon;
- a reading sensor movably disposed under the document tray to read the document;
- a bracket to support the reading sensor;
- a guide shaft to guide the movement of the reading sensor;
- a first ground unit to electrically connect the bracket and the guide shaft;
- and
- a second ground unit to electrically connect the guide shaft and the main body frame.
A method of preventing electromagnetic radiation from negatively affecting performance of an image forming apparatus having a scanner including a document tray on which to place a document and a scanning sensor assembly movably disposed under the document tray to read the document, the method comprising:
- electrically connecting a metal bracket that supports a scanning sensor in the scanning sensor assembly to a grounded main body frame of the image forming apparatus.
