Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
As shown in fig. 1 and 2, the embodiment discloses a scanning pen with a scanning light supplementing and light homogenizing structure, which comprises a housing 1, and a main board 9, a camera 4, a camera support 3, a scanning light supplementing lamp 5, a light supplementing lamp FPC6 and a control chip 10 which are arranged in the housing 1. One side of the shell 1 is provided with a function key 12, and a dodging lampshade 2 and a scanning switch 7 are arranged below the shell 1.
The control chip 10 is designed on the mainboard 9, and the control chip 10 is electrically connected with the camera 4, the light supplement lamp FPC6, the function key 12 and the scanning switch 7.
The camera 4 comprises an image sensor and a lens, the lens is located at the camera shooting window and faces the scanning window, the image sensor is located above the lens, and the lens is used for collecting an image of the scanned paper surface 16 when the scanning light supplement lamp 5 illuminates the scanned paper surface 16 and transmitting the collected image information to the image sensor. The camera 4 is assembled in the shell 1 through the camera bracket 3 and the dodging lamp shade 2.
A camera window 20 corresponding to the camera 4 is arranged above the dodging lamp shade 2, and a scanning window 21 is arranged below the dodging lamp shade 2, wherein the scanning window 21 corresponds to a scanning area. At least one scanning light supplement lamp 5 is arranged on the outer side of the light homogenizing lampshade 2. The lens is located at the image capturing window 20 and faces the scanning window 21, so as to ensure that the lens receives the light transmitted from the scanning window 21. Even light lamp shade 2 is added reflection granule injection moulding by transparent material and is formed, and when scanning light filling lamp 5 was lighted, light was through the even light effect of even light lamp shade 2, becomes a surface light source to whole even light lamp shade to make whole scanning region lighted. When the document characters need to be scanned, the scanning window 21 of the dodging lampshade 2 of the scanning pen is placed on the scanned paper surface 16, the scanning switch 7 is triggered, at this time, the scanning light supplement lamp 5 starts to be electrified and lighted, and meanwhile, the camera 4 also starts to scan. The light-emitting light beam formed by the point light source light 17 emitted by the scanning light supplement lamp 5 firstly illuminates the outer wall of the dodging lamp shade 2, then the whole dodging lamp shade 2 is lightened through scattering, and a plurality of scanning light supplement lamps 5 are preferably arranged to lighten the whole dodging lamp shade 2. As shown in fig. 3, preferably, the light-equalizing lampshade 2 may be made of a transparent material, and the reflective particles 15 are uniformly dispersed inside (so that the whole light-equalizing lampshade is semitransparent), when the light beam passes through the light-equalizing lampshade 2, a part of the light beam directly passes through the lampshade to form a light beam 18 passing through the lampshade and then illuminating the scanned area, and another part of the light beam is reflected by the internal reflective particles to form a reflected light beam 19, which is equivalent to forming a virtual light source, and the light beam is reflected inside the lampshade for multiple times to change the whole lampshade into a two-dimensional virtual light source matrix, thereby illuminating the inside of the whole light-equalizing lampshade 2. And surrounded by the scanning window 21 of the whole dodging lamp shade 2 in the region of being scanned just in time, the pointolite of scanning light filling lamp 5 has become the luminous area source of whole lamp shade through dodging lamp shade 2 like this to the messenger is evenly illuminated by the scanning region, prevents to cause the discomfort to eyes because of local brightness is too strong during the long-time use.
Preferably, the two opposite sides of the dodging lamp housing 2 each have an inclined wall extending straight from one side of the camera window 20 to the same side of the scanning window. The two scanning fill-in lamps 5 correspond to the walls on the two sides respectively. This communications wall makes 2 inner walls slopes of dodging lamp shade on the one hand, makes the light of scanning window get into camera 4 smoothly, and on the other hand makes each position of this communications wall all and scanning light filling lamp 5 between do not have and shelters from to the light that makes scanning light filling lamp 5 send can illuminate whole communications wall.
The installation of the dodging light housing 2 can take the following preferred example, on the one hand, the dodging light housing 2 is fixed together with the camera head support 3 by means of M1.4 screws 8 to form one assembly. On the other hand, the dodging lampshade 2 is provided with at least one lampshade hook which is matched with a boss or a hook on the shell. Advantageously, the upper portion of the dodging lamp shade 2 is provided with a first lamp shade hook 11 which just matches with the boss structure at the function key of the shell 1, the lower portion of the dodging lamp shade 2 is provided with a second lamp shade hook 13 extending upwards, and the inner wall of the shell 1 is provided with a shell hook 14 which matches with the second lamp shade hook 13. After the first lampshade clamping hook 11 and the second lampshade clamping hook 13 are assembled with the lug boss and the shell clamping hook 14, the dodging lampshade assembly is firmly assembled in the shell 1.
Preferably, the scanning light supplement lamp 5 is installed below the camera support 3 and forms an included angle α with the camera support 3, so that the central axis of the scanning light supplement lamp 5 is close to the center of the corresponding scanned area. The scanning light supplement lamp 5 is welded on the light supplement lamp FPC6, and the light supplement lamp FPC6 is arranged between the dodging lampshade 2 and the camera support 3 and connected to the main board 9.
The assembly process of the embodiment:
1. the light supplement lamp FPC6 is arranged on the dodging lampshade 2.
2. Pressing camera support 3 on light filling lamp FPC6, scanning light filling lamp 5 forms an contained angle with the horizontal plane, makes the axis of scanning light filling lamp 5 be close to correspond on the regional center of being scanned.
3. Then, the camera 4, the scanning switch 7, the main board 9, and the like are mounted.
4. The camera bracket 3 is fixed with the dodging lamp shade 2, the main board 9 and the like by 2M 1.4 screws 8 to form a component.
5. The assembly is arranged in the shell 1 and is tightly and firmly buckled with the shell 1 through the first lampshade clamping hook 11 and the second lampshade clamping hook 13.
