Description

Technical Field

[0001] This utility model relates to the field of scanning equipment technology, and in particular to a flip-type scanning device. Background Technology

[0002] Scanners are used to convert documents, photographs, and other materials into computer-readable formats for human use. Flip-type scanners are widely used in work and daily life due to their simple structure and ease of operation.

[0003] Among the main structural forms of flip-type scanners, such as the scanner with application number 200920105397.5, a long guide shaft is set along the horizontal direction of the scanner in the scanning processing device. A linear CCD frame is set on the long shaft, and a lens is set on the linear CCD frame. It can slide along the long shaft in the horizontal direction. When the user scans an image, the image is placed upside down on the glass table and the flip-top is closed for scanning. However, a transmission mechanism is required to drive the lens to move to complete the scanning action. The existence and operation of the transmission mechanism makes the structure relatively complex and difficult to maintain and repair. On the other hand, the movement of the lens from front to back and its resetting during the scanning process also increases the scanning time. Utility Model Content

It can quickly and conveniently scan paper documents that need to be scanned by simply transmitting and reflecting light. It is easy to operate and the overall structure is simple, which is conducive to maintenance and repair.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a flip-type scanning device, comprising:

[0006] The bottom shell has an internal cavity.

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figures 1 to 4 As shown, a flip-top scanning device includes a bottom shell 10, a glass support plate 20, a reflector assembly (including a reflector 31 and a light strip 32), a camera assembly 40, and a top cover 50. The bottom shell 10 has an inner cavity 100. The glass support plate 20 is disposed on the bottom shell 10 to support paper (the paper to be scanned). The reflector 31 is disposed at an angle in the inner cavity 100 and is located below the glass support plate 20. The light strip 32 is disposed in the inner cavity 100 on the side wall of the bottom shell 10 and is located below the side of the glass support plate 20. The camera assembly 40 is disposed in the inner cavity 100 and is located on the opposite side of the reflector 31. The field of view of the camera assembly 40 covers the reflector 31. The top cover 50 is hinged to the bottom shell 10 and, after rotation, closes onto the glass support plate 20 and seals the inner cavity 100.

[0029] In this invention, the paper to be scanned is placed on the glass support plate 20, and one corner of the paper to be scanned is positioned at the positioning point 200 formed by the bottom shell 10 and the glass support plate 20, ensuring that the paper to be scanned is in the correct position. After the top cover 50 is closed, the bottom shell 10 and the inner cavity 100 are sealed, forming a visual and light isolation from the outside world. The light strip 32 can illuminate the content on the paper to be scanned, and the glass support plate 20 can transmit the content on the paper to be scanned. Then, the content on the paper to be scanned is reflected to the camera assembly 40 through the reflector 31. Since the reflection range of the reflector 31 matches the field of view of the camera assembly 40, the camera assembly 40 feeds back the received content, completing the entire scanning process.

[0030] The positional structure (relationship) of the glass carrier plate 20, reflector 31 and camera assembly 40 inside the bottom shell 10 is simple. It achieves fast and convenient scanning of paper documents such as A3 / A4 paper through simple transmission and reflection principles. The operation is simple. Moreover, the overall structure is simple, which is conducive to maintenance and repair.

[0031] Specifically, the bottom shell 10 includes a shell 11, an inner frame 12, a first top plate 13, and a second top plate 14. The inner frame 12 is disposed inside the shell 11 to strengthen the structure. The first top plate 13 is disposed on the upper end of one side of the inner frame 12, and a positioning groove 130 is provided on the side wall of the first top plate 13 at an incline. One end of the reflector 31 is embedded in the positioning groove 130, and the other end abuts against the bottom wall of the shell 11. A pair of second top plates 14 are disposed on opposite sides of the inner frame 12. The opposite sides of the glass support plate 20 are respectively disposed on the second top plates 14 and abut against the upper end of the first top plate 13. This invention forms an inner cavity 100 through the housing 11, and places the glass support plate 20 and the reflector 31 in the inner cavity 100 to facilitate the sealing of the upper cover 50. The glass support plate 20 is positioned on the second top plate 14 and is further supported by the first top plate 13. When the first top plate 13 has a positioning baffle 131 on the side away from the inner cavity 100, the first top plate 13 can position the side of the glass support plate 20 by the abutment between the side wall of the glass support plate 20 and the positioning baffle 131, ensuring the accurate position of the glass support plate 20. Moreover, under the premise of having the above-mentioned functions, the first top plate 13 can also install and position the reflector 31 through the positioning groove 130 on its side wall (and cooperate with the bottom of the bottom shell 10). The multiple functions of the first top plate 13 can optimize the structure of the bottom shell 10.

[0032] Preferably, a horizontal slot 140 is provided on the side wall of the second top plate 14, and the end of the glass support plate 20 is embedded in the horizontal slot 140, which can prevent the glass support plate 20 from detaching upward from the second top plate 14 and ensure the installation stability of the glass support plate 20.

[0033] Furthermore, the length of the reflector 31 is equal to the length of the positioning groove 130. The lateral limiting of the first top plate 13 can ensure that the position of the reflector 31 is stable and accurate, and can ensure that it matches the field of view of the camera assembly 40.

[0034] In addition, two positioning grooves 130 with different tilt angles can be provided on the side wall of the first top plate 13 to enable the mirror 31 to be set with different tilt angles and adapted to the camera assembly 40.

[0035] Based on the above configuration, in order to ensure that the reflector 31 can be stably supported in the inner cavity 100, the housing 11 is provided with a stop block 15 that is locked to the inner frame 12. The lower end of the stop block 15 abuts against the bottom wall of the housing 11, and the lower end of the reflector 31 abuts between the stop block 15 and the bottom wall of the housing 11. Furthermore, two locking holes can be provided on the stop block 15. The stop block 15 can be positioned at different positions on the inner frame 12 through the locking holes at different positions, which can respectively cooperate with the two positioning grooves 130 with different inclination angles.

[0036] Preferably, the camera assembly 40 includes a tilting bracket 41 and a CMOS camera 42. The tilting bracket 41 is mounted on the housing 11 or the inner frame 12, and its tilting angle is conducive to forming a suitable shooting angle. The CMOS camera 42 is mounted on the upper end of the tilting bracket 41. The camera assembly 40 has two CMOS cameras that are spaced apart, meaning that the simultaneous shooting by the two spaced-apart CMOS cameras can capture the content of large-format paper more seamlessly.

[0037] The top cover 50 includes a cover body 51 and a black foam board 52 disposed on the cover body 51. The cover body 51 is hinged to the bottom shell 10 and rotates to cover the glass support plate 20 with the black foam board 52, which can form a better sealing effect. The cover body 51 is provided with an extension plate 511, which makes it easy to open the top cover 50 by hand.

[0038] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
