Image scanner having a single contact glass and contact-type image sensor movable under automatic document feeder

An image scanner, comprising:

• a single contact glass placed on a main body, said contact glass having a first range through which a first original document is passed to be scanned, and a second range over which a second original document is placed to be scanned;
• an image sensor scanning said first original document at a fixed position in the first range, and said image sensor scanning said second original document while the image sensor moves through the second range;
• an automatic document feeder arranged on the first range of the contact glass, the automatic document feeder introducing said first original document through an introducing path to said fixed position and ejecting said first original document through an ejecting path from said fixed position;
• wherein the introducing path is formed from an introducing orifice to said fixed position, the introducing orifice being located at a side of the second range of the contact glass;
• and
• wherein the ejecting path is formed in a same conveying direction as the introducing path.

• an image sensor scanning said first original document at a fixed position in the first range, and said image sensor scanning said second original document while the image sensor moves through the second image;
• an automatic document feeder arranged on the first range of the contact glass, the automatic document feeder introducing said first original document through an introducing path to said fixed position and ejecting said first original document through an ejecting path from said fixed position;
• and
• wherein the ejecting path is formed from said fixed position to an ejecting orifice, and
• first and second rollers arranged in the ejecting path feeding the first original document to said ejection orifice, wherein the first roller is arranged in said automatic document feeder and the second roller is arranged in said main body;
• wherein the introducing path is formed from an introducing orifice to said fixed position, the introducing orifice being located at a side of the second range of the contact glass.

An image scanner comprising:

• a contact means placed on a main body for contacting original documents, said contact means having a first range through which a first original document is passed to be scanned, and a second range over which a second original document is placed to be scanned;
• sensor means for scanning said first original document at a fixed position in the first range, and said sensor means scanning said second original document while the sensor means moves through the second range;
• automatic document feeder means arranged on the first range of the contact means for introducing said first original document through an introducing path to said fixed position and for ejecting said first original document through an ejecting path from said fixed position;
• wherein the introducing path is formed from an introducing orifice to said fixed position, the introducing orifice being located at a side of the second range of the contact means;
• and
• wherein the ejecting path is formed from said fixed position to an ejecting orifice, and wherein the ejecting path includes an upper side and a lower side, wherein said upper side includes a part of the automatic document feeder means and said lower side includes a part of the contact means.
