Embodiment
The scan module of adjustable optical scanner of the present invention (with reference to Fig. 3) has a light source 1100, a reflector group 1400, an optical lens group 1510 and an optical sensor, such as being Charged Coupled Device (CCD) 1600 in its shell 1700.When scanning, light source 1100 irradiation manuscripts 1200 obtain an image light through reflection or transmission.Reflector group 1400 is made up by a plurality of reflecting optics (1401,1402,1403), and be disposed on the light path of image light, it can place manuscript 1200 images on the light-passing board 1300 to import reflector group 1400, and the reflection of process reflector group 1400 is resent to optical lens group 1510.Optical lens group 1510 can receive the image light of the manuscript 1200 that reflector group 1400 transmitted and image in Charged Coupled Device 1600.
Adjustable optical lens fixing means of the present invention, be in integrally formed mode, on shell 1700, form an optical lens microscope base 1710, this optical lens microscope base 1710 has many grooves 1711, and each bar groove 1711 can be in order to configuration fixed optics lens combination 1510 corresponding optical lenses (for example being 1511,1512,1513).The method more provides a fixed cap 1520, is fixed on the optical lens microscope base 1710, more firmly optical lens (for example being 1511,1512,1513) is clamped and fastened between lens mount 1710 and the fixed cap 1520.And fixed cap 1520 is fixed in the mode on the optical lens microscope base 1710, comprises mode of fixing with trip and the mode of utilizing the screw locking.
Then narrate adjustable optical lens fixed sturcture of the present invention.Wherein, optical lens group 1510 has multi-disc optical lens (as 1511 among Fig. 3,1512,1513).And to its fixed form, as shown in Figure 4, the present invention is on shell 1700, design an optical lens microscope base 1710, the groove shape that this optical lens microscope base 1710 runs through for both ends open, have many grooves 1711 in this groove, each bar groove 1711 can be fixed in the mode of Chemical Adhesion in order to configuration optical lens group 1510 corresponding optical lenses 1511,1512,1513 again.So make optical lens group 1510 between optical sensor 1600 and the reflector group 1400, on the light path of image light, to receive this image light and to image in optical sensor 1600.Can add a fixed cap 1520 again in addition again is fixed on the optical lens microscope base 1710, cover surely in week therewith between 1520 with the groove that optical lens group 1510 is clamped and fastened on optical lens microscope base 1710, can firmly be fixed on the optical lens microscope base 1710 to guarantee optical lens group 1510 more.Sectional view after its assembling as shown in Figure 5.
And fixed cap 1520 is fixed in the mode on the optical lens microscope base 1710, comprises with trip 1522 being fastened on draw-in groove 1712 (as shown in Figure 4) on the optical lens microscope base 1710; Or, lock second screw hole 1713 (as shown in Figure 6) of optical lens microscope base 1710 with first screw hole 1524 of screw 1800 via fixed cap 1520; Or the some gluing such as closes at alternate manner.
Wherein, optical lens microscope base 1710 is in integrally formed mode, forms with main body cover 1700 when injection molding.And the relative position of 1711 of each bar grooves also can form earlier when injection molding accurately, makes subsequent optical lens combination 1510 can reach desired relative position and spacing when assembling, and unnecessary adjustment through repeatedly.So can save many man-hours and cost, and reduce part number (the optical lens sleeve 520 as is well known).The position of each bar groove 1711 also can be adjusted on mould.
In addition, the section shape of the groove of optical lens microscope base 1710, for cooperating the shape of optical lens, for example the optical lens 1511,1512,1513 of present embodiment is circular, the section shape of the groove of optical lens microscope base 1710 then is semicircle.So the section shape of the groove of optical lens microscope base 1710 can be Any shape, to cooperate the shape of optical lens.
In the same manner, fixed cap 1520 is for cooperating the shape of optical lens 1511,1512,1513, can be designed to have a semi-circular cross-section as shown in Figure 3, two ends reach the groove shape for running through opening, fixes with ease of assembly.And the section shape of this groove also is can cooperate the shape of optical lens and be shape arbitrarily.
Aforementioned recess quantity and kind are not limited to as shown in the figure three, and its visual Demand Design makes fixed sturcture of the present invention look demand and adjusts the lens of changing variety classes and quantity.
According to the embodiment of the invention described above as can be known, the present invention has following advantage at least:
(1) optical lens microscope base and main body cover are one of the forming, and can reduce the part number to reduce cost.
(2) relative position between groove also can form earlier when injection molding accurately, make the subsequent optical lens combination when assembling, can reach desired relative position and spacing, and do not need adjustment through repeatedly, so can save many assembling man-hours and cost.
(3) formed a plurality of groove, visual demand and adjust the change lens kind and quantity, make the range of application of this fixed sturcture more flexible.
