Description

Double-sided image scanning module

The utility model relates to an image scanning device.

Existing scanners or facsimile machines mostly scan single-sided document images, or scan double-sided documents, which must be manually turned over, which is of course inconvenient. As shown in Figure 1: the file 12 is placed in the file box 13, and the file 12 enters the scanning area 14 through the turning path 18. When the sensor on the roller 17 touches the paper end of the document 12, the sensor starts the image reading device 11 for scanning. Turn around the path 15, exchange the front and back sides and enter the file box 13 to complete the image reading of the second side. When scanning one side, the document 12 is placed on the transparent document platform 19, and the image reading device 11 moves along the platform 19 on the axis 16 to scan the entire document image. This structure has a long turning path, long waiting time, complicated structure and high manufacturing cost.

The purpose of the utility model is to provide a double-sided image scanning module with a relatively simple structure.

The purpose of this utility model is achieved in this way: a double-sided image scanning module, which includes: a paper feeding device, a paper picking device, a scanning area, a rotary device, an induction device and an image reading device, and is characterized in that: the paper picking device Located on the same side of the paper feeding device; the scanning area has a document travel path connecting the paper feeding device and the paper taking device, a transparent window and a direction control roller located on the opposite side of the transparent window; the rotary device has an input path and an output path and are respectively connected The scanning area; the sensing device is located at the paper output end of the rotary device; the image reading device is located outside the transparent window.

In the above design, the input path of the rotary device is used to guide the scanned documents from the scanning area, and the output path is used to flip the scanned document from one side to the other side, and guide the flipped document to the scanning area; the sensing device is used to exit the rotary device , send a direction control signal to the direction control wheel to make it rotate in the opposite direction; the image reading device is used to read the first side of the document when it passes through the transparent window, and read its second side when the document passes through the transparent window through the rotary device , so as to achieve a good effect of completing a double-sided image scanning module with a relatively simple structure.

The utility model is described further below by accompanying drawing and embodiment:

Fig. 1 is the structural representation of existing single-sided image reading device to scan double-sided images; Fig. 2 is the structural representation of the best embodiment of the utility model; Fig. 3 is the structural representation of another preferred embodiment of the utility model; Fig. 4 is a structural schematic diagram of the utility model for a single-sided scanner;

As shown in Figure 2: the utility model includes: a paper feeding device 210, a paper taking device 211, a scanning area 212, a rotary device 31, an induction device 28 and an image reading device 27, and it is characterized in that the paper taking device 211 is located at the The same side of the device 210; the scanning area 212 has a document travel path connected to the paper feeding device 210 and the paper taking device 211, a transparent window 26 and a direction control roller 25 located on the opposite side of the transparent window 26; the rotary device 31 has an input path 32 and An output path 33 is connected to the scanning area 212 respectively; the sensing device 28 is located at the paper output end of the rotary device 31 ; and the image reading device 27 is located outside the transparent window 26 . Wherein, the paper feeding device 210 includes a first file box 21 for placing documents and a first idler wheel 23 for sequentially guiding the documents into the scanning area 212 . Wherein, the paper feeding device 210 includes a second file box for placing documents and a second idler wheel for sequentially guiding the documents from the scanning area 212 to the second file box. Wherein, the turning device 31 includes rollers located on its input and output paths 32 and 33 for guiding the document from the first direction to the second direction. Wherein, the image reading device 27 is a single contact type. Wherein, the image reading device 27 is a single charge-coupled type. Wherein, the turning device 31 is detachable. Wherein, the rotary device is installed on a machine cover. Wherein, the double-sided image scanning module further includes a modulation and demodulation module for transmitting the image read by the image reading device 27 to the remote end. Wherein, the distance between the direction control roller 25 and the rotary device 31 is greater than the length of a document. so that paper does not jam.

Wherein, there are at least two idle wheels 29, 30 in the rotary device 31, in order to control the entry and exit of documents. The rotation direction of the idler wheel 30 in the paper feeding direction is the same as that of the first idler wheel 23 above the first file box 21 , and the rotation direction of the idler wheel 29 in the paper output direction is the same as that of the idler wheel 30 .
