After modulating the magnification that meets design load, the optimal imaging position then may change to some extent.In order to allow to obtain the optimal imaging position once more, must be as illustrating among Fig. 2 A, adjust camera lens 260 once more and move forward and backward to a lens location along optical axis 250 and temporarily fix, and must adjust circuit board 210 once more, make photo-sensitive cell 220 must think that optical axis 250 passes through.
After adjusting the optimal imaging position, therefore magnification will be adjusted and change to some extent.At this moment, only need follow the relative position that utilizes mitre joint face 235,245 to adjust circuit board bearing seat 240 and lens bearing seat 230 as illustrating among Fig. 2 B, can obtain another image distance once more, can modulate the magnification that meets design load.Then, adjusting circuit board 210 again makes photo-sensitive cell 220 must think that optical axis 250 passes through to get final product.
It is above-mentioned that to utilize camera lens of the present utility model carrying module modulation optimal imaging position be a kind of convergence process with the process that meets the magnification of design load, that is, can draw optimal imaging position and the magnification that meets design load at last.
Please refer to Fig. 3 A, it illustrates is the stereographic map that carries module according to the camera lens of preferred embodiment of the present utility model.Find out that by knowing in graphic lens bearing seat 230 and 240 of circuit board bearing seats are to see through mitre joint face 235 to couple mutually with mitre joint face 245, the relative displacement of mitre joint face 235 and mitre joint face 245 thus, and can modulate the magnification that meets design load.
Also can find out that in Fig. 3 A the coupling mode that circuit board bearing seat 240 and lens bearing seat are 230 can be the mode of bolt, and the coupling mode of 240 of circuit board 210 and circuit board bearing seats can also be the mode of bolt.This is for providing the coupling mode of temporarily fixing to each other or permanent fixation.
Can have slotted hole 310 on the circuit board bearing seat 240, on lens bearing seat 230, then can have circular hole (not showing among the figure), and have screw thread in the circular hole.Because of circuit board bearing seat 240 has slotted hole 310, thus can littlely loosen the screw a little 320 with the mitre joint face 245 that makes circuit board bearing seat 240 can be on the mitre joint face 235 of lens bearing seat 230 little moving.Can obtain until modulation circuit plate load bearing seat 240 to one new relative positions one meet the magnification of design load after, screw screw 320 again and circuit board bearing seat 240 can fixedly be coupled on the lens bearing seat 230 get final product.
In like manner, can also have slotted hole 330 on the circuit board 210, on circuit board bearing seat 240, then can have circular hole (not showing among the figure), and have screw thread in the circular hole.Because of circuit board 210 has slotted hole 330, so can littlely loosen the screw a little 340 with make circuit board 210 can be on the positive composition surface 247 of circuit board bearing seat 240 little moving, can make photo-sensitive cell (not showing among the figure) by optical axis (not showing among the figure) when being passed through until modulation circuit plate 210 to one new relative positions, screw screw 340 again and circuit board 210 can fixedly be coupled on the circuit board bearing seat 240 get final product.
Please refer to Fig. 3 B, it illustrates is the exploded view that carries module according to the camera lens of preferred embodiment of the present utility model.Can know the relativeness of finding out 210 of lens bearing seat 230, circuit board bearing seat 240 and circuit boards in graphic.Be positioned at the slotted hole 310 on the circuit board bearing seat 240 and be positioned at the corresponding relation of 350 of circular holes on the lens bearing seat 230, and the corresponding relation that is positioned at the slotted hole 330 on the circuit board 210 and is positioned at 360 of circular holes on the circuit board bearing seat 240 also cocoa clearly seen by we look.
As illustrating among Fig. 3 B, can have guide groove 370 on the mitre joint face 235, then can have guide rail 380 on the mitre joint face 245 corresponding to guide groove 370.Guide rail 380 can slide in guide groove 370, mitre joint face 245 can smoothly be moved, in view of the above to modulate the magnification that meets design load on mitre joint face 235.On the contrary, also can have guide rail on the mitre joint face 235, then can have the guide groove corresponding to guide rail on the mitre joint face 245, guide rail also can slide in guide groove, mitre joint face 245 can smoothly be moved on mitre joint face 235, modulate the magnification that meets design load in view of the above.
From the above, camera lens carrying module provided by the utility model, it focuses on seeing through the adjustment to the relative position between two inclined-planes, and makes image distance can obtain modulation, and then can obtain meeting the magnification of design load.By the utility model, can solve the shortcoming that traditional camera lens carrying module can't be modulated magnification.
It should be noted that, the geometry of each object only is an embodiment of the present utility model among the embodiment, be not in order to limit applicable elements of the present utility model, anyly be familiar with this operator and all can be adjusted and reach and the similar function of the utility model, only still do not break away from spirit of the present utility model.
The disclosed camera lens carrying of the utility model the foregoing description module, the advantage that has is: the magnification that can modulate image makes it meet design load, makes the size of the scan-image that is scanned can meet required.
In sum; though the utility model discloses as above with a preferred embodiment; right its is not in order to limit the utility model; anyly have the knack of this operator; in not breaking away from spirit and scope of the present utility model; when being used for a variety of modifications and variations, therefore protection domain of the present utility model is as the criterion when looking accompanying the claim person of defining.
