Detailed Description of the Embodiment

[0028] The following describes the utility model in detail with reference to the accompanying drawings.

[0029] As Figure 1 — Figure 4As shown, the present utility model provides a scanning device, including:

[0030] A scanning device, including: an upper housing 1, the upper housing 1 including a scanning module 11 for scanning paper; a lower housing 2, the lower housing 2 including a guard plate 21 for supporting the paper; the upper housing 1 and the lower housing 2 are snapped together to form a paper feed channel that is open at both ends for the paper to move bidirectionally; the edge of the guard plate 21 is provided with a plurality of first bumps 211 at intervals, the lower housing 2 is provided with a second bump 22, the first bumps 211 and the second bump 22 are arranged in a staggered manner to form a zipper-like structure, and the outer edges of the first bumps 211 and the second bump 22 are both provided with chamfers.

[0031] The present utility model forms the upper housing 1 and the lower housing 2, and the upper housing 1 and the lower housing 2 are snapped together to form a paper feed channel that is open at both ends for the paper to move bidirectionally, so that the paper has multiple ways to enter and exit the paper feed channel; the lower housing 2 is provided with the guard plate 21, and a zipper-like structure is formed between the guard plate 21 and the lower housing 2 through the staggered arrangement of the first bumps 211 and the second bump 22, thereby preventing the paper from jamming when it is conveyed to the position of the guard plate 21. At the same time, the outer edges of the first bumps 211 and the second bump 22 are both provided with chamfers, making the conveying process of the paper smoother and further preventing the paper from jamming and being damaged.

[0032] As Figure 3 、 Figure 4 shown, the outer surface of the lower housing 2 facing the upper housing 1 is provided with a plurality of first ribs 23, the outer surface of the upper housing 1 facing the lower housing 2 is provided with a plurality of second ribs 12, the plurality of first ribs 23 are arranged in a staggered manner, the first ribs 23 and the second ribs 12 are arranged in a staggered manner, and the outer edges of the first ribs 23 and the second ribs 12 are both provided with chamfers.

[0033] Specifically, in this embodiment, both the upper housing 1 and the lower housing 2 are made of metal materials. The upper housing 1 and the second rib 12 are integrally designed, and the lower housing 2 and the first rib 23 are also integrally designed. The number of the first ribs 23 and the second ribs 12 can be adjusted according to actual needs, but there should be at least more than three. A plurality of the first ribs 23 are arranged in a staggered manner with each other, and the first ribs 23 and the second ribs 12 are arranged in a vertical staggered manner, thereby ensuring that the paper can move horizontally in the paper feed channel. At the same time, the outer edges of the first ribs 23 and the second ribs 12 tend to have a smooth transition with the surface of the lower housing 2, forming a smooth slope, so that the contact surface between the paper and the ribs is smoother, reducing friction and wear, which is beneficial to further avoiding the phenomenon of paper jamming.

[0034] As Figure 3 shown, the upper housing 1 is provided with bosses 111 protruding at both ends corresponding to the scanning module 11. The end of the guard plate 21 is provided with a first groove 212. The lower housing 2 is provided with second grooves 24 at both ends corresponding to the guard plate 21. The first groove 212 communicates with the second groove 24, and the first groove 212 and the second groove 24 enclose a limiting groove matching the boss 111.

[0035] As Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 shown, the surface of the guard plate 21 is provided with a slope-shaped structure. The scanning module 11 and the guard plate 21 are correspondingly arranged. A scanning area is arranged between the scanning module 11 and the guard plate 21. The height of the scanning area is equal to the thickness of the paper, and a sensor 3 and a sensor 4 are arranged on one side of the guard plate 21.

[0036] As Figure 7 shown, the bottom of the guard plate 21 is provided with a first spring group 25. The guard plate 21 and the lower housing 2 are elastically connected through the first spring group 25. The bottom edge of the guard plate 21 extends to be provided with a first buckle 213 for preventing the guard plate 21 from falling off. The first buckle 213 is buckled and connected with the lower housing 2.

[0037] Specifically, in this embodiment, the guard plate 21 is elastically connected to the upper housing 1 through the first spring group 25. When the boss 111 abuts against the limiting groove, the boss 111 presses the first groove 212 downward until it is on the same horizontal line as the second groove 24. At this time, the distance between the top of the guard plate 21 and the scanning module 11 (i.e., the scanning area) is equal to the thickness of a piece of paper, which can just accommodate a piece of paper passing through the scanning area. This design is beneficial to the focusing of the scanning component, so that the information on the paper can be scanned and recognized clearly quickly, thereby improving the scanning efficiency of this scanning device; the width range of the scanning area is 85MM, and compared with the existing scanning devices, the scanning range of this device is wider; and the design of the first buckle 213 facilitates the disassembly, replacement and maintenance of the guard, and can also prevent the elastic action of the first spring group 25 from popping out and dropping the guard plate 21.

[0038] In addition, the sensor 3 is arranged at the entrance of the paper feeding channel. When the sensor 3 senses the paper, the system is started. The sensor 4 is arranged on one side close to the guard plate 21. When the paper reaches the position of the sensor 4, the sensor 4 will calculate the length of the paper, and the system calculates the starting time of the scanning module 11 according to the length of the paper and the current conveying speed of the paper, thereby reflecting the automated management of the entire device, without manual operation, saving time and effort.

[0039] In another embodiment, the scanning module 11 includes at least one CIS, which is used to scan lottery tickets to identify whether they are in a printable state. It can be set as a scanner made by CIS technology. The Chinese name of CIS is a contact image sensor. It uses a contact photosensitive element (photosensitive sensor) for photosensing. At a position 1 mm to 2 mm below the scanning platform, 300 to 600 red, green, and blue three-color LED (light-emitting diode) sensors 4 are closely arranged together to generate a white light source, replacing the complex mechanisms such as the CCD array, lens, fluorescent tube, and cold cathode ray tube in the CCD scanner, and changing the optical, mechanical, and electrical integration of the CCD scanner into the mechanical and electrical integration of the CIS scanner. The scanner made by CIS technology has the advantages of small volume, light weight, and low production cost.

[0040] As Figure 2 shown, a conveying rubber roller 26 protrudes from the surface of the lower housing 2 facing the upper housing 1, and the upper housing 1 is provided with a pressing wheel 13 adapted to the conveying rubber roller 26.

[0041] As Figure 2 、 Figure 4As shown, the conveying rubber roller 26 is divided into a first circular shaft 261 and a second circular shaft 262. The interval between the first circular shaft 261 and the second circular shaft 262 is set to 0 - 40 MM. The number of the pressing wheels 13 is set to two, and the two pressing wheels 13 are respectively arranged corresponding to the first circular shaft 261 and the second circular shaft 262.

[0042] As Figure 2 , Figure 5 As shown, a spring pressing plate 14 is arranged inside the upper housing 1. A second spring group 15 is arranged between the spring pressing plate 14 and the pressing wheel 13. The spring pressing plate 14 and the pressing wheel 13 are elastically connected through the second spring group 15.

[0043] Specifically, in this embodiment, the spring pressing plate 14 is fixedly connected to the upper housing 1. The pressing wheel 13 and the conveying rubber roller 26 are arranged at the entrance end of the paper feeding channel for conveying the paper in the paper feeding channel. The first circular shaft 261 and the second circular shaft 262 are respectively close to the inner wall of the lower housing 2. When the user inserts the paper into the paper feeding channel, the first circular shaft 261 and the second circular shaft 262 respectively abut against the paper and provide a guiding and correcting effect for the paper. In addition, the design of dividing the conveying rubber roller 26 into the first circular shaft 261 and the second circular shaft 262 is more cost - saving than the design of setting the conveying rubber roller 26 as a single circular shaft.

[0044] As Figure 6 As shown, the scanning module 11 is arranged inside the upper housing 1, and several second buckles 16 are arranged inside the upper housing 1. The scanning module 11 is snap - fitted to the upper housing 1 through the second buckles 16.

[0045] Specifically, in this embodiment, the number of the second buckles 16 is set to four. The scanning module 11 is arranged in a rectangular structure. Every two of the buckles are respectively arranged at intervals on the long sides of the scanning module 11, thereby fixing the scanning module 11 inside the upper housing 1 in all directions to prevent it from falling.

[0046] As Figure 1 , Figure 4 As shown, a coaxial buckle 27 is arranged on the lower housing 2. A slot 17 is arranged at the corresponding position of the upper housing 1 for the coaxial buckle 27. The upper housing 1 and the lower housing 2 are buckled through the coaxial buckle 27 and the slot 17. And baffles 28 for correcting the position of the paper are arranged on both sides of the lower housing 2 corresponding to the paper feeding channel.

[0047] Specifically, in this embodiment, the design of buckling the upper shell 1 and the lower shell 2 by setting the coaxial buckle 27 facilitates the user to separate the upper shell 1 and the lower shell 2, so as to clean, replace, and repair the internal parts of the device, or take out the paper stuck in the paper feeding channel, etc. The number of the coaxial buckles 27 is set to two, and the two coaxial buckles 27 are respectively arranged at both ends of the lower shell 2, which improves the stability when the upper shell 1 and the lower shell 2 are buckled. At the same time, since the coaxial buckles 27 can move coaxially and open and close simultaneously, it is convenient for the user to operate with one hand and improves the usability of the device. In addition, the design of the baffle 28 enables the paper entering the paper feeding channel to move along the edge of the baffle 28. Therefore, the baffle 28 has the functions of guiding and correcting.

[0048] In summary, it can be seen that the present utility model has the excellent characteristics described above, so that it can enhance the efficiency never before achieved in the prior art during use and has practicability, becoming a product with extremely high practical value.

[0049] The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manners and application scopes. The content of this specification should not be construed as a limitation to the present utility model.
