Abstract:
A double-side scanning mechanism for capturing images of a paper having two pages includes a second transparent element disposed corresponding to an outer side of a first transparent element and parallel to the first transparent element. A paper conveying device conveys a paper to pass between the first and the second transparent elements with a first page facing the first transparent element. The paper is flipped and passes over the outer side of the second transparent element with a second page facing the second transparent element. An image scanning module is disposed corresponding to an inner side of the first transparent element, for capturing the image of the first page when the paper passes between the first and the second transparent elements, and capturing the image of the second page when the paper passes over an outer side of the second transparent element.
Abstract:
A paper feeding apparatus including a paper pickup roller assembly, a paper conveying roller assembly, a one-way driving assembly, and a reverse driving assembly is provided. The one-way driving and the reverse driving assembly are connected to a driving device, such as a motor, wherein the one-way driving assembly is engaged with the paper pickup roller assembly only in one direction to drive the paper pickup roller assembly forward as the driving device rotates forward and stop driving the paper pickup roller assembly as the driving device rotates backward, and the reverse driving assembly is provided for driving the paper conveying roller assembly to constantly rotate forward for conveying the paper sheet to move forward no matter whether the driving device rotates forward or backward.

Abstract:
A double-side scan device for performing a single-side scan operation or a double-side scan operation selectively includes a document conveyer, a first transparent device, a second transparent device, and an image scan module. The image scan module moves to one side of the first transparent device to capture an image of one surface/side of a document and moves to one side of the second transparent device to capture an image of the other surface/side of the document, respectively.

Abstract:
A print control module for a thermal printer includes a housing, a transmission device, a first driving mechanism, a second driving mechanism, and a power switching mechanism all installed in the housing. The transmission device includes a motor, and a transmission gears set for transmitting power of the motor. When the motor rotates in a first direction, the power switching mechanism transfers power of the motor to the first driving mechanism, and when the motor rotates in a direction opposite to the first direction, the power switching mechanism fixes the first driving mechanism and transfers power of the motor to the second driving mechanism.
Abstract:
An optical mechanism installed in an office machine, which has a machine base defining an internal space, and a paper-feeding mechanism arranged on the machine base, the paper-feeding mechanism having an inside receiving space and a bottom incident zone for the passing of light. The optical mechanism has an optical-path device formed of an image sensor and an optical module and mounted in the internal space inside the machine base, and a light-focusing structure mounted in the receiving space inside the paper-feeding mechanism above the incident zone for increasing optical path.
Abstract:
A document feeder for multifunction printers or scanners offers high reliability and speedy paper-picking, -separating and -feeding functions. It comprises a picking module, a separating module and a feeding module. Since the three modules take turns to deliver paper, the paper can be picked at a lower speed, separated at a medium speed and then fed at a high speed. In addition, the separating module comprises a clutch. When the paper was fed by the feeding module, the clutch is activated to provide an interval between papers and to prevent papers from plucking.
Abstract:
A media conveying mechanism located in a media data recorder for conveying media mainly includes a driving motor to provide driving power needed. A first clutch to control the operation of a pickup roller. A second clutch to control rotation direction of an intermediate roller, a sensor to detect the conveying process of the media and control the operation of the second clutch. By deploying the two clutches, conveying quantity of the media in a unit time period can be effectively improved.
Abstract:
A heating and fixing device for toner particles is provided, which includes a pressing element, at least one elastic element, a tube-shaped film, and a pressing roller. The elastic element is provided for generating force to press the pressing element constantly. The heating element is provided for heating the pressing element through the heated side. The film is disposed around the pressing element and the heating element, wherein the film slides relative to the pressing element, and the pressing element presses against the film from the inner side of the film and transfers heat to the film by heat conduction. The pressing element presses the film to contact the pressing roller, so that the recording medium is pressed and heated when traveled between the pressing roller and the film.
