Publication number: 20130321547Abstract: An inkjet printer includes a platform for a print medium, a print-head carriage, and an airflow controller. The print-head carriage defines a plurality of air channels, each of which has an air intake and an air outtake. The air outtake is located on a bottom surface of the print-head carriage and faces the platform and during any movement of the print-head carriage blows airflow towards the print medium, forcing the print medium flat against the platform and thus to the optimal distance for the delivery of ink droplets.Type: ApplicationFiled: May 13, 2013Publication date: December 5, 2013Applicant: HON HAI PRECISION INDUSTRY CO., LTD.Inventors: KUNG-HUANG TSAI, SHU-YA CHIANG

Patent number: 7898700Abstract: A document surface micro-adjust mechanism for an optical scanner. The optical scanner has an outer casing with a transparent document platform in the upper section. An optical lens is enclosed inside the outer casing. The document surface micro-adjust mechanism uses a carrier chassis to embed the transparent document platform. One end of the carrier chassis is hinged upon the upper wall of the outer casing while the other end of the carrier chassis has a through hole to be engaged to a locking hole on a latching structure attached to the upper section of the outer casing. A locking element passes through the through-hole to engage with the locking hole. An elastic element is positioned between the carrier chassis and the latching structure. Depth of the locking element inside the locking hole may be adjusted to vary optical distance from the document surface of the transparent document platform to the optical lens inside the scanner.Type: GrantFiled: August 31, 2006Date of Patent: March 1, 2011Inventors: Yin-Chun Huang, Shu-Ya Chiang

Patent number: 7595917Abstract: A document scanner with a light focusing device downward formed on a document support panel is disclosed. The document scanner is provided with a chassis including a light source and an image sensing device. A scanning window made of light-transmitting material is formed in an area of the document support panel.

Patent number: 7038819Abstract: The present invention relates to a depth of field adjustment device and method for an automatic document feeder. The automatic document feeder has a guiding groove for placing an object to be scanned. The guiding groove has a scanning window for providing image picking-up for an optical chassis. An adjustable suppressing mechanism located at the guiding groove in corresponding to the scanning window may drive the object to be scanned to pass through an optimal depth of field height of the scanning window. First, at least a part of the pre-scanned object is fed in to be located between the adjustable suppressing mechanism and the scanning window. The depth of field height is then adjusted and changed by the adjustable suppressing mechanism. And, the image of the pre-scanned object is compared with a pre-stored image. After the pre-scanned objected has been judged to be located at the optimal depth of field height, the adjustable suppressing mechanism is fixed and the pre-scanned object is sent out.Type: GrantFiled: November 13, 2001Date of Patent: May 2, 2006Inventors: Po-Hua Fang, Shu-Ya Chiang
