Description

retractable scanner

technical field

The present invention relates to a scanner, and more particularly to a scanner with telescoping function for scanning documents of different sizes.

Background technique

With the substantial improvement of computer performance, and the high development of Internet and multimedia technology, in addition to using digital cameras (Digital Camera, DC) to directly capture image patterns, other image input operations related to documents or pictures require optical scanning. Optical Scanner to capture analog images of text or patterns and convert them into digital signal output, which helps users display, identify, edit, store and output image files on computers or other electronic products action.

According to the input method of document images, optical scanners can be divided into hand scanners, sheet feed scanners, drum scanners and flatbed scanners ( Flatbed Scanner) and so on. It is worth noting that since the flatbed scanner has a relatively stable image scanning quality and has the function of scanning reflective or transmissive manuscripts (negatives, transparencies, etc.), it can be equipped with an Automatic Document Feeder (Automatic Document Feeder, ADF) to scan stacks of documents of the same size, making flatbed scanners one of the most common optical scanners available today.

As shown in FIG. 1 , it is a schematic top view of a known flatbed scanner. Referring to FIG. 1 , the top of the flatbed scanner 100 usually has a transparent glass 110 for placing a document to be scanned. In addition, a transmission mechanism 120 is configured in the scanner 100 , and the transmission mechanism 120 is composed of a belt 122 and a motor 124 to drive the scanning module 130 that is also configured in the scanner 100 .

And when the bottom plate 224 of the second housing 220 turns over to the outer surface of the first housing 210 , an open circuit is formed between the second signal line 224 a and the first signal line 216 a. Therefore, before scanning, if the control device 270 receives a conduction signal, the control device 270 judges that the scanning area is a large scanning area. On the contrary, if the control device 270 receives a disconnection signal, the control device 270 judges that the scanning area is a small scanning area.

In addition, in addition to automatically judging the size of the current scanning area according to the signal of the connection or disconnection obtained from the above-mentioned signal line, it is also possible to scan manually, for example, on the scanner or on the scanner connected to the scanner. directly select the size of the scanning area on the computer.

Based on the above, the retractable scanner of the present invention has at least the following advantages:

1. The scanner of the present invention has a telescopic function, which can change the size of the scanner according to the size of the document to be scanned, and has strong functionality and high practicability.

2. The scanner of the present invention can manually select or automatically judge the size of the current scanning area according to the signal of the path or disconnection obtained from the signal line, so as to perform the scanning action, and its operation is convenient and simple.

3. The scanner of the present invention has a telescopic function, and the shrunk scanner is small in size and easy to carry, which can lead to the trend of product miniaturization.
