Patent number: 5878319Abstract: An image scanner includes a single contact glass placed on a main body. The contact glass has 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 scans the first original document at a fixed position in the first range, and the image sensor scans the second original document while the image sensor moves through the second range. An automatic document feeder is arranged on the first range of the contact glass to introduce the first original document through an introducing path to the fixed position and to eject the first original document through an ejecting path from the fixed position. The introducing path is formed from an introducing orifice to the fixed position, the introducing orifice being located at a side of the second range of the automatic document feeder. Further, an ejecting path is formed from the fixed position to an ejecting orifice.Type: GrantFiled: August 4, 1997Date of Patent: March 2, 1999Assignee: Ricoh Company, Ltd.Inventor: Yoshiya Itoh

Patent number: 5734483Abstract: There is provided an image scanner in which no shock is applied to a carrier moving an image sensor when the carrier is moved between an automatic document feeder and a contact glass on which an original document is placed. The image sensor is pressed against the contact glass by a spring. A plurality of rollers are provided between the image sensor and the contact glass so that the image sensor is pressed against the contact glass via the rollers. The rollers are separated from the contact glass by a separating member when the image sensor passes an area between the contact glass and the automatic document feeder. A housing of the image scanner is made of a plastic.Type: GrantFiled: September 17, 1996Date of Patent: March 31, 1998Assignee: Ricoh Company, Ltd.Inventor: Yoshiya Itoh
