In addition, follow after into direction D leaves first transmission combination 140 at object O1, O2, first elastic component 142 that is in compressive state and second elastic component 143 provide elastic force to make first driving member 1400 and second driving member 1402 relative close towards the opposite direction of arrow A 1, A2 respectively respectively, and first connecting rod 341 also can drive first gear 340 simultaneously with second connecting rod 343 and second gear 342 relatively rotates towards the opposite direction of arrow R1, R2 respectively, and then replys the state before the start.In like manner, driving object O1, O2 at the 3rd driving member 1410 and the 4th driving member 1412 follows after into direction D leaves housing 10, the 3rd elastic component 144 that is in compressive state and the 4th elastic component 145 provide elastic force to make the 3rd driving member 1410 and the 4th driving member 1412 relative close towards the opposite direction of arrow A 3, A4 respectively respectively, and third connecting rod 345 and the 4th connecting rod 347 also can drive the 3rd gear 344 simultaneously and the 4th gear 346 relatively rotates towards the opposite direction of arrow R3, R4 respectively, and then reply the state before the start.
It should be noted that the number of teeth of first gear 340 and second gear 342 can be identical or different, and the number of teeth of the 3rd gear 344 and the 4th gear 346 also can be identical or different, decides on practical application.
See also Fig. 7, Fig. 7 is the schematic diagram according to the Image sensor apparatus 3 ' of third embodiment of the invention.Image sensor apparatus 3 ' is with the main difference of aforesaid Image sensor apparatus 3, the 3rd gear 344 of Image sensor apparatus 3 ' and 340 engagements of first gear, and the 4th gear 346 and 342 engagements of second gear.Therefore, in this 3rd embodiment, when first driving member 1400 relative with second driving member 1402 away from or near the time, first gear, 340 to the 4th gears 346 and first connecting rod 341 to the 4th connecting rods 347 promptly can drive simultaneously the 3rd driving member 1410 relative with the 4th driving member 1412 away from or close.It should be noted that with the element of same numeral shown in the 4th to 6 figure, its structure, action principle are roughly the same, do not repeat them here among Fig. 7.
See also Fig. 8 to Figure 10 B, Fig. 8 is the schematic diagram according to the Image sensor apparatus 5 of fourth embodiment of the invention, Fig. 9 A and Fig. 9 B are the Image sensor apparatus 5 among Fig. 8 has the object O1 of thickness T 1 in order to sensing the process of transporting schematic diagram, and Figure 10 A and Figure 10 B have the process of the transporting schematic diagram of the object O2 of thickness T 2 in order to sensing for the Image sensor apparatus 5 among Fig. 8.Image sensor apparatus 5 is with the main difference of aforesaid Image sensor apparatus 1, first driving member 5400 of first transmission combination 540 of the conveyer 54 of Image sensor apparatus 5 and second driving member 5402 are arranged at the both sides of travel path P respectively rotationally, and the 3rd driving member 5410 of second transmission combination 541 and the 4th driving member 5412 are arranged at the both sides of travel path P respectively rotationally.In this 4th embodiment, first driving member 5400, second driving member 5402, the 3rd driving member 5410 and the 4th driving member 5412 are all made by deformable material.In practical application, deformable material can be rubber or foam, but not as limit.It should be noted that with the element of same numeral shown in Fig. 1 to Fig. 3, its structure, action principle are roughly the same, do not repeat them here among Fig. 8 to Figure 10 B.
Before object O1, O2 enter first transmission combination 540, but contact of first make contact C1 essence or the noncontact second contact point C2, but and contact of the 3rd contact point C3 essence or noncontact the 4th contact point C4, can design according to practical application.
Shown in Fig. 9 A and Figure 10 A, when object O1, O2 entered first transmission combination 540, first driving member 5400 and second driving member 5402 produced distortion and form one and equal the thickness T 1 of object O1, O2, the gap of T2.At this moment, equal thickness T 1, the T2 of object O1, O2 apart from essence between the second contact point C2 of the first make contact C1 of first driving member 5400 and second driving member 5402, but with the centre line L 1 of guaranteeing object O1, O2, L2 all essence remain in identical travel path P and go up and move.As mentioned above, because travel path P is the field depth DOF that is positioned at image sensor 12, although therefore object O1, O2 have different thickness T 1, T2, but image sensor 12 all sensing article O1, O2 and produce the sharp image of corresponding object O1, O2.
Shown in Fig. 9 B and Figure 10 B, when object O1, O2 entered second transmission combination 541, the 3rd driving member 5410 and the 4th driving member 5412 produced distortion and form one and equal the thickness T 1 of object O1, O2, the gap of T2.At this moment, equal thickness T 1, the T2 of object O1, O2 apart from essence between the 3rd contact point C3 of the 3rd driving member 5410 and the 4th contact point C4 of the 4th driving member 5412, but with the centre line L 1 of guaranteeing object O1, O2, L2 all essence remain in identical travel path P and go up and move.In addition, after object O1, O2 left first transmission combination 540, first driving member 5400 and second driving member 5402 promptly can be replied the state before the distortion.In like manner, after the 3rd driving member 5410 and the 4th driving member 5412 drove object O1, O2 and leave housing 10, the 3rd driving member 5410 and the 4th driving member 5412 promptly can be replied the preceding state of distortion.
Compared to prior art, the center line that the conveyer of Image sensor apparatus of the present invention can make the different object of a plurality of thickness all essence remains on the identical travel path and moves.Therefore, although these objects have different thickness, but the image sensor of Image sensor apparatus of the present invention these objects of sensing and produce the sharp image of corresponding these objects all.In other words, the user can use Image sensor apparatus of the present invention to come the different object of a plurality of thickness of sensing, and does not need to buy a plurality of specific Image sensor apparatus respectively at the different object of a plurality of thickness.
The present invention is described by above-mentioned related embodiment, yet the foregoing description is only for implementing example of the present invention.Must be pointed out that the embodiment that has disclosed does not limit the scope of the invention.On the contrary, change of being done and retouching without departing from the spirit and scope of the present invention all belongs to scope of patent protection of the present invention.
