Background

Scanners (scanners) are devices that convert graphical or image information into digital signals in a scanning manner using electro-optical technology and digital processing technology. Scanners are commonly used in computer peripheral devices by capturing images and converting them into digitized input devices that a computer can display, edit, store, and output. The scanner can be used for scanning three-dimensional objects such as photos, text pages, drawings, art pictures, photographic negatives, film films, even textiles, label panels, printed board samples and the like, and extracting and converting original lines, graphs, characters, photos and plane real objects into devices capable of being edited and added into files. The scanner belongs to the input system in Computer Aided Design (CAD), and forms a computer processing system before screen printing through computer software, a computer and an output device (a laser printer and a laser plotter) interface, so that the scanner is suitable for Office Automation (OA) and is widely applied to label panels, printed boards, printing industries and the like.

The existing common scanners are integrated with a printer, and also have high-speed cameras with independent scanning functions, and the scanning devices are generally large in size and inconvenient to carry; at the same time, these devices are not very expensive. With the development of science and technology, smart phones are more and more popular, and the photographing performance of smart phones is stronger and stronger, so that a lot of software capable of scanning through photographing appears on the mobile phones, such as scanning all-purpose king and the like. When the software is used, the mobile phone needs to be unlocked, the software needs to be opened, then the mobile phone is held by a hand, and the file needing to be scanned is photographed, so that the file scanning can be completed.

The circuit schematic of this scheme is shown in fig. 7; meanwhile, the arrangement of the two pull ropes 41 enables the detection to be more reliable.

As another detection scheme, as shown in fig. 8-11, the angle detection unit 40 includes a first strip 46 and a second strip 47 arranged in parallel, and the cross sections of the first strip 46 and the second strip 47 are concave, as shown in the enlarged area of fig. 9; the first strip 46 is fixed on the first seat 21, a sliding block 48 is arranged in a groove of the first strip 46, a side pressing switch 481 is arranged on the sliding block 48, and the switch detection circuit 45 is arranged in the sliding block 48; the second strip 47 is fixedly mounted on the supporting unit 30, and the middle part of the second strip 47 is hinged with a push rod 49, the middle part is not a central position, but any part in the middle, and in actual use, the hinge point should be deviated to one side of the first strip 46. When the supporting unit 30 rotates to a set angle, the overhanging end of the push rod 49 moves to the position of the slide block 48 along the groove of the first strip 46 and abuts against the pressing-down side pressing switch 481, and the switch detection circuit 45 is used for detecting the pressing state of the pressing-down side pressing switch 481 and driving the photographing unit 10 to photograph when the pressing-down side pressing switch 481 is pressed down. The hinged position of the push rod 49 and the length of the push rod 49 can be set according to requirements, in the invention, the hinged point of the push rod 49 is arranged by deviating to one side of the first strip 46, and the length of the push rod 49 ensures that the push rod 49 can be reversely stored in the second strip 47, so that when the angle is not required to be detected, the push rod 49 can be conveniently stored, the random overturning of the supporting unit 30 is not influenced, and the carrying is not influenced.

As shown in fig. 10, the slider 48 is provided with a positioning screw hole 482, a plurality of positioning holes 461 are uniformly arranged in the groove of the first strip 46 along the length direction at intervals, a positioning screw is arranged in the positioning screw hole 482 of the slider 48, and the end of the positioning screw extends into the positioning hole 461 to realize the positioning of the slider 48. The positioning holes 461, the positioning screw holes 482 and the positioning screws are arranged, so that the position of the slide block 48 can be adjusted, and the setting angle for triggering the supporting unit 30 to take a picture can be realized. In practical use, the positioning holes 461 do not need to be formed in all of the grooves of the first strip 46, but only a part of the grooves need to be formed with the positioning holes 461.
