Problems solved by technology

In order for the hardware part of the scanning device to have sufficient strength and durability, the above two plastic components must have sufficient size, however, this point often becomes the main bottleneck in the process of minimizing the size of the entire scanning device
In addition, since the manufacturing precision of plastic components is often not precisely controlled, there are occasional situations where two plastic components cannot be precisely combined into the main body of the scanning device

Embodiment Construction

[0030] 1 to 8 are schematic diagrams of components on a sheet-fed scanning device according to an embodiment of the present invention. The scanning device 100 of this embodiment is used to scan an image of an object to be scanned placed on a tray (both the tray and the object to be scanned are not shown in the figure). As shown in FIGS. 1 to 8 , the scanning device 100 includes the following five main components:

[0031] 1. The rigid main frame 200 , which can be made of metal or other high-rigidity materials, is used to provide a movement path for the tray to move forward into / backward out of the scanning device 100 , and to set up other components included in the scanning device 100 . In addition, a tray sensing unit 220 is also provided on the rigid main frame 200 for sensing whether the user has placed the tray at the entrance of the moving path. The moving path has a first and a second vertical side in the vertical direction, and a first and a second lateral side in the...

Abstract

This invention discloses a paper-feeding scanning device used in scanning an image of an object on a tray including: a rigid master frame for providing a moving path for the tray moving into / out of the scanning device and spanning other parts of said scanning device, a loading module mounted on the upper side of the moving path for irradiating light on the object and sensing the light reflected or transmitted by the object to scan the image of the object, a lower light source set on the lower side of the path for irradiating light on the object, a driving module used in moving the tray into / out of the scanning device and a directional module used in keeping the tray on the moving path when it moves in the scanning device.

Description

[0001] The present invention relates to an image scanning device, in particular to a paper-fed scanning device with a smaller size due to modularization. Background technique [0002] Image scanning devices (such as scanners, multifunction machines, and copiers) are electronic devices commonly used in homes or offices today. Generally speaking, image scanning devices can be divided into two types: sheet-fed image scanning devices and flat-bed image scanning devices. Among them, sheet-fed image scanning devices can often provide more convenient image scan service. [0003] Some sheet-fed image scanning devices use a specific tray to place the object to be scanned. When the tray is moved in / out of the scanning device, the light source in the scanning device will shine light on the object to be scanned. The scanning device A sensing module (such as a charge coupled device (CCD)) in the sensor can sense the light reflected (or transmitted) by the object to scan the image of the o...
