  • Patent number: 12129136
    Abstract: A sheet input module includes: a tray; a support plate pivotally disposed on the tray to form a first included angle with the tray, wherein the support plate supports multiple sheets; and a sheet-stopper structure being pivotally disposed on the tray and providing a stopping function for the sheets. In an interlocking mode, the sheet-stopper structure is driven by the support plate according to a change of the first included angle and rotated relatively to the tray to adjust a second included angle between a stopping surface of the sheet-stopper structure and the sheets. A printing device using the sheet input module is also provided.
    Type: Grant

  • Patent number: 7984907
    Abstract: 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.

  • Patent number: 7466457
    Abstract: 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.
