Patent number: 10712703Abstract: A sensing device includes a housing, a supporting component, a grating module, a first roller, a second roller, and a control unit. When a media contacts with the second roller, the second roller drives the first roller to move the supporting component relative to the housing according to a thickness of the media, so as to adjust positions of the first roller and a grating wheel of the grating module relative to the housing. When the media drives the second roller to rotate, the second roller drives the first roller to rotate the grating wheel. The control unit determines whether the media proceeds at a predetermined speed according to a corresponding sensing signal generated by the grating module during rotation of the grating wheel, which allows a user to recognize a progress state of the media.Type: GrantFiled: July 9, 2018Date of Patent: July 14, 2020Assignee: AVISION INC.Inventors: Chi-Yao Chen, Ku-Ming Chen, Chia-Ching Lin

Patent number: 9521288Abstract: A sheet-fed scanner comprising a scan channel, a feeding unit, a transmitting unit, a background sheet, a background light source and a scan module is provided. The feeding unit is disposed at an inlet of the scan channel for feeding a document. The transmitting unit transmits the document to pass through the scan channel. The background sheet is disposed on a side of the scan channel, and has a first surface and a second surface. The first surface faces towards the scan channel. The background light source faces towards the second surface to provide an intermittent light signal to the background sheet, so that the background sheet correspondingly displays an intermittent variation background image on the first surface. The scan module is disposed on another side of the scan channel, and captures a document image of a document and the intermittent variation background image to generate scan data accordingly.Type: GrantFiled: May 19, 2015Date of Patent: December 13, 2016Assignee: Avision Inc.Inventors: Thomas Sheng, Ku-Ming Chen

Patent number: 8177219Abstract: A sheet feeder has a transmission mechanism which includes an output gear mesh with a transmission gear train, and a switch element, disposed between the transmission gear train and the output gear, for switching a rotational direction of the output gear. The switch element includes a movable arm, a driving gear driven by the transmission gear train, a switching gear set attached to the arm and meshing with the driving gear, and a clutch device for restricting movement of the arm to enable the switching gear set to be disengaged from the output gear. When the output gear meshes with the switching gear set, the output gear and a transmission shaft of the sheet feeding mechanism may change the direction of their rotation. When the output gear is disengaged from the switching gear set, the output gear and the transmission shaft of the sheet feeding mechanism are not driven by a power source.Type: GrantFiled: September 11, 2009Date of Patent: May 15, 2012Assignee: Avision Inc.Inventors: Ku-Ming Chen, Chia-Huei Lin, Sung-Po Cheng

Patent number: 7984907Abstract: In an automatic feeder and an image acquiring apparatus, a cover is rotatably connected to a body through a first pin and openable and closable with respect to the body. A roller gear rotates a transporting roller to transport a sheet. An actuating member is attached to the first pin and driven by rotation of the first pin. A middle gear, displaceable by the actuating member, is selectively engaged with a power-output gear and the roller gear so as to transmit a power to the roller gear. An actuating member moves the middle gear to be engaged with the power-output gear and the roller gear when the cover is closed upon the body, and moves the middle gear to be disengaged from at least one of the power-output gear and roller gear when the cover is opened.Type: GrantFiled: December 28, 2010Date of Patent: July 26, 2011Assignee: Avision Inc.Inventor: Ku Ming Chen

Patent number: 7466457Abstract: A sheet-fed scanner capable of scanning multiple scan lines for image signal calibration includes a housing, a sheet-feeding mechanism, a first scanning module, a first actuator and a first calibration sheet. The sheet-feeding mechanism disposed in the housing feeds a document across a scan region. The first scanning module rotatably mounted in the housing scans a front side of the document fed across the scan region. The first calibration sheet is fixed in the housing and disposed in the scan region. The first actuator drives the first scanning module to rotate such that the first scanning module senses a plurality of scan lines on the first calibration sheet to obtain a first calibration standard for calibrating a first image signal of the front side of the document. Thus, it is possible to avert any flaws in image quality caused by the contaminated calibration sheet.Type: GrantFiled: May 1, 2006Date of Patent: December 16, 2008Assignee: Avision Inc.Inventor: Ku Ming Chen
