Description
Technical field
The utility model is relevant for a kind of optical sensor fixture, and particularly relevant for a kind of optical sensor fixture that is applied in the optical scanner module.
Background technology
Input, processing and processing at image, become after a kind of popular interest, scanner just becomes one of basic outfit of many computer users, and it can be with literal or image documents such as file, magazine, books, pictures, and scanning input computer is also handled.In various scanners, platform-type scanner is the most frequently used a kind of, and in platform-type scanner, scanning module is to be installed on transparent platform below in the mode that can spur back and forth, places file on the transparent platform with scanning.Again, scanning module itself is not had power, therefore needs for example drive as transmission mechanisms such as stepper motor, gear, belts.When desire uses a platform-type scanner to scan a file again, file must be placed on the transparent platform, again the file cover plate be covered, smooth with the compressing file in transparent platform, scan then.
In known optical scanner module (with reference to Fig. 1), comprise a light source 100, a reflector group 400, an optical lens 500, an optical sensor 600 (for example being charge coupled cell (CCD, Charged Couple Device)) and a main body 700.Aforementioned light source 100, reflector group 400, optical lens 500, and optical sensor 600 etc. all are disposed in the main body 700.When scanning, light source 100 irradiations place the manuscript 200 on the light-passing board 300, obtain an image light through reflection or transmission.Reflector group 400 is made up by a plurality of speculums (401,402,403), and is disposed on the optical path of image light, and it can import manuscript 200 images in the reflector group 400, and the reflection of process reflector group 400 is resent to optical lens 500.The image light of the manuscript 200 that the reflector group 400 that can receive optical lens 500 is transmitted also images in charge coupled cell 600.

Please refer to Fig. 3, be the floor map of the utility model preferred embodiment optical scanner module.In the same manner, the optical scanner module comprises a light source 1100, a reflector group 1400, an optical lens 1500, a main body 1700 and an optical sensor, such as being charge coupled cell (CCD) 1600.Wherein, aforesaid light source 1100, reflector group 1400, optical lens 1500, and optical sensor 1600 etc. all are disposed in the main body 1700.When scanning, light source 1100 irradiations place the manuscript 1200 on the light-passing board 1300, obtain an image light through reflection or transmission.Reflector group 1400 is made up by a plurality of speculums (1401,1402,1403), and is disposed on the optical path of image light, and it can import manuscript 1200 images in the reflector group 1400, and the reflection of process reflector group 1400 is resent to optical lens 1500.The image light of the manuscript 1200 that the reflector group 1400 that can receive optical lens 1500 is transmitted also images in charge coupled cell 1600.
Wherein, as shown in Figure 4, charge coupled cell 1600 is to be fixedly arranged on (the trapezoidal base rear side of the fixture of optical lens 1500) on the main body 1700, the image light of the manuscript 1200 that comes to receive optical lens 1500 transmission.
Refer again to Fig. 5, can find out that by its three-dimensional exploded view optical sensor fixture of the present utility model mainly comprises: a plurality of (present embodiment is two) studs 1800 and a plurality of (present embodiment is two) nut 1900.Wherein, stud 1800 is one not have the bolt of bolt head, and its nut side 1812 and bolt are gone into 1820 of sides and had a ring-type fixed head 1830.Wherein a stud 1800 and the relative position end view of a nut 1900 wherein are shown in Fig. 6,7.Fig. 6 is its end view after decomposing, and Fig. 7 is the end view of its group after standing.
The nut side 1810 of each stud 1800 penetrates on the substrate 1610 of charge coupled cell 1600 a wherein through hole 1612, lock in nut side 1810 with nut 1900 again, the substrate 1610 of charge coupled cell 1600 is clamped and fastened between ring-type fixed head 1830 and the nut 1900.So, can in this step, adjust the deflection (skew) of the substrate 1610 of charge coupled cell 1600.
Bolt goes into that side 1820 then semi-permanently is locked on the main body 1700, in the screw hole 1712 of grooved opening 1710.1830 of aforesaid ring-type fixed heads are embedded in the grooved opening 1710, and its thickness is less than the degree of depth of grooved opening 1710, so that the substrate 1610 of charge coupled cell 1600 can be smooth comprehensively on main body 1700.
The end of nut side 1810 is a flat slotted head 1812 again, has a flat recess, is suitable for so that word screwdriver (figure does not illustrate) is in the flat recess application of force rotation of this flat slotted head 1812 one by one, and adjustment stud 1800 moves forward and backward along its axis direction.When adjusting stud 1800 when its axis direction moves forward and backward, the substrate 1610 of charge coupled cell 1600 still is clamped and fastened between ring-type fixed head 1830 and the nut 1900 (does not influence the good deflection of its adjusted), so, can adjust the distance of 1500 of charge coupled cell 1600 and optical lens, adjust correct focal depth position to cooperate.
From the above, by the stud 1800 and the nut 1900 of the utility model optical sensor fixture, mode that promptly can simple mechanism makes charge coupled cell 1600 can distinguish independent its deflection (skew) and the correct focal depth position adjusted.
Again, 1610 of the substrates of nut 1900 and charge coupled cell 1600 also can add clamping one packing ring 2000, with the strength of the substrate 1610 that increases nut 1900 locking charge coupled cells 1600.
At last, after the deflection of adjusting the substrate 1610 of determining good charge coupled cell 1600 and correct focal depth position, also can go into side 1820 and be put glue with the junction 1840 of main body 1700 in the bolt of each stud 1800, as shown in Figure 7, with fixing stud 1800 in main body 1700, avoid stud 1800 to be shaken and become flexible, influence the position of substrate 1610 on the aforementioned three degree of freedom direction of adjusting of charge coupled cell 1600.
In sum, optical sensor fixture of the present utility model is the stud of flat slotted head with an end, with and on the ring-type fixed head cooperate the simple mechanism design of nut, make charge coupled cell can distinguish independent its deflection and the correct focal depth position adjusted.
According to above-mentioned embodiment of the present utility model as can be known, the utility model has following advantage at least: be the stud of flat slotted head with an end, with and on the ring-type fixed head cooperate the simple mechanism design of nut, make charge coupled cell can distinguish independent its deflection and the focal depth position of finely tuning between itself and optical lens adjusted, make the purpose that increases the correct focal depth position of adjusting charge coupled cell, become simple possible.
Though the utility model with the preferred embodiment explanation as above; right its is not in order to limit the utility model; anyly have the knack of this technology personage; in not breaking away from spirit and scope of the present utility model; when can doing a little change and retouching, therefore protection range of the present utility model is when looking being as the criterion that claim defines.
