In the mounting bracket 2, and between the mounting bracket 2 and the lens assembly 1.The reflection of the lens assembly 1
It is the second angle β that angle is formed between the reflecting surface 131 of mirror 13 and the screen frame 34 of the handheld device 3.It is described
The size that third angle γ, the third angle γ are formed between abutment face 220 and the bottom edge 222 is equal to first angle
α.After 3 partial receipt of the handheld device is in the inner cavity 27, the support portion 211 of the pedestal 21 supports the handheld device
The rear shell 35 of 3 bottom end, the handheld device 3 is obliquely resisted against on the abutment face 220 of the butting section 22, and described hand-held
35 part of rear shell of equipment 3 is overlapped with the extension inclined-plane 26.The handheld device 3 be limited in the limiting section 24 with it is described
Between butting section 22, further, the handheld device 3 be limited in the limit section 242 and the abutment face 220 it
Between, the limiting section 24 prevents the handheld device 3 along the parallel cradle bottom surface 2130 and far from the side of the interconnecting piece 23
It is moved to A.
First angle α, the second angle β, the third angle γ are acute angle.First angle α is more than
The second angle β.Correspondingly, the fixed angles α 1 and the third angle γ are all higher than the second angle β.
Further, the size of first angle α can be 70 degree to 80 degree between；Correspondingly, the fixed angles α 1
Size can be 70 degree to 80 degree between.
Further, the size of the second angle β is 51 degree to 61 degree.
Further, the second angle β is 61 degree, and first angle α is 70 degree；Alternatively, the second angle β
It it is 61 degree, first angle α is 80 degree；Alternatively, the second angle β is 51 degree, first angle α is 80 degree；Alternatively,
The second angle β is 51 degree, and first angle α is 70 degree.
It is further preferable that the second angle β is 56 degree, first angle α is 75 degree.
The operation principle of described image harvester is：The lens assembly 1 is removably mounted on described hold to set
Second angle is formed on standby 3, and the handheld device 3 is mounted on the support portion 211 of the mounting bracket 2, and will

It is noted that the reflecting surface 131 reflect it is scanned in the horizontal sweep region 5 and described anti-
It penetrates face 131 to be located in the conical scan region 132, and vertical height of the reflecting surface 131 apart from the horizontal sweep region 5
The vertical height H for spending horizontal sweep region 5 described in the focal length with the front camera 4 is substantially suitable, therefore, it is described preposition
It is scanned in the horizontal sweep region 5 reflected comprising the reflecting surface 131 in the image that the scanning of camera 4 generates,
And scan in generated image, the scanned image in the horizontal sweep region 5 that the reflecting surface 131 reflects is more
Clearly, thus the scanner program is identified mainly for the reflected content of the reflecting surface 131 and matching treatment.
It, will to improve to the scanned scan resolution and discrimination in the embodiment of the utility model
The scanned top edges abut and paste the edge that the neat limiting section 24 intersects with the horizontal table top 6, and the quilt
The middle position at the edge that the middle position of scanning object is substantially intersected with the limiting section 24 with the horizontal table top overlaps.From
And after starting the scanner program in the handheld device 3, the reflecting surface 131 of the speculum 13 on the lens assembly 1 will
The scanned front camera 4 for being reflected into the handheld device 3 comprehensively being positioned in the horizontal sweep region 5, it is described
Front camera 4 to it is described it is scanned be scanned generation image, to realizing to the scanned auto-focusing and
Shooting, the image that the scanner program generates scanning are handled, and further, the scanner program, which can start, gives birth to scanning
At image be identified and match, and obtain the corresponding resource of the image to be shown to user.
In the embodiment of the utility model, if ensure the size that first angle α is be 70 degree to 80 degree it
Between, and the technical solution of the utility model then may be implemented between 51 to 61 degree in the size of second angle, with realization pair
The scanned auto-focusing and shooting.
When being scanned using the image collecting device of the utility model, the lens assembly 1 is positioned over by scanned
Can in the horizontal sweep region 5 that scan, the lens assembly 1 reflect in the horizontal sweep region 5 it is scanned extremely
The front camera 4, after user starts the scanner program of the handheld device 3, you can realize to described scanned
Auto-focusing and shooting scanning, further, the image that the scanner program generates scanning is handled, and further can
Start the image for generating scanning to be identified and match, and obtains the corresponding resource of the image to be shown to user；In addition,
The utility model without using person hold the handheld device 3 and it is scanned shoot, the handheld device 3 scan when,
The both hands of user can also handle other items；By auto-focusing and shooting scanning, simplifies user and shoot scanning
Operation improves the clarity of the scanned scanning, and is convenient for the scanned identification.
It is noted that the interconnecting piece 23 can be semicircle, it can also vertical or mode in other shapes
Connect the pedestal 21 and the butting section 22.The upper surface of the butting section 22 can be a flat surface, or other shapes
Shape, but the length H2 of the top margin 221 positioned at the upper surface is necessarily less than the length H3 on the bottom edge 222 so that the third
Angle γ is equal with first angle α, and is maintained between 70 degree to 80 degree.
It is apparent to those skilled in the art that for convenience and simplicity of description, only with above-mentioned practical new
The preferable specific implementation mode of type is illustrated, and but protection scope of the utility model is not limited thereto, any to be familiar with
Those skilled in the art within the technical scope disclosed by the utility model, all answer by the change or replacement that can be readily occurred in
Cover and is within the protection scope of the utility model.Therefore, the scope of protection of the utility model should be with the protection of claim
Subject to range.
