Below the effect that can be easier to understand technical problem of the present utility model, technical scheme, characteristics and be reached is described in detail by the specific embodiment conjunction with figs..

See also Fig. 1 and Fig. 2, the utility model includes an optical mechanism 1, a slide fixed cell and a slide rail 3.

This optical mechanism 1, it includes a slide guide bar 11, an eyeglass 12, a camera lens 13 and an OPTICAL SENSORS 14.

This slide guide bar 11 is as a lead track, and it makes its scanning to fix this lantern slide on can be moved to a slide fixed cell, and this slide guide bar 11 has a tip 111.Be provided with a slide rail 3 in the front support leg 21 of base 2 and the rear leg 22, slide rail 3 is inserted in the hole of front support leg 21 and rear leg 22, base 2 can be restricted to and move forward and backward.Behind motor driven base 2, can provide the required displacement of scanning motion (direction shown in the arrow under the slide rail 3 as shown in Figure 2).

The eyeglass 12 of optical mechanism 1 interior forward end penetrates resulting light behind the slide in order to reflection, and intersegmental part is provided with a camera lens 13 in the optical mechanism 1, the light that comes from eyeglass 12 reflections can be throwed really enter OPTICAL SENSORS 14 imagings.There is the slide guide bar 11 once polishing optical mechanism 1 front end below, and the part weight with optical mechanism 1 conducts to the slide fixed cell on the one hand, can assist optical mechanism 1 to slide against on skating-aid board 18 and the slide fixed cell on the other hand.This eyeglass 12 can be a mirror or other have the form of reflecting surface.This camera lens 13 will scan the reflected image of lantern slide, so that its OPTICAL SENSORS 14 is focused accurately, this camera lens 13 can amplify or dwindle the lantern slide of scanning on demand.OPTICAL SENSORS 14 can be a CMOS image sensor, a CCD camera or other forms of OPTICAL SENSORS, gets final product so long as can catch the scan-image of reflection accurately.

This eyeglass 12, camera lens 13 and image sensor 14 are installed in same housing, in case when production and assembly, these image capturing elements are fixed on the position respect to one another.Promptly since the installing of all scan-image capturing element of the utility model with respect to the fixed-site of other elements, so this scanning means can make the displacement of image capturing element hardly, so the utility model keeping is simple, and has superior scanning quality.

See also Fig. 2 A, in order to keep excellent contact between this fixed cell 17 and the slide guide bar 11, can use the method for a moment of elasticity, this optical mechanism 1 contacts with a fulcrum 15, flexible member 16 (for example: spring or metal wire bent) can provide suitable elasticity that the end of optical mechanism 1 is pushed to, then have a strength to push to down make it on the slide fixed cell slide guide bar 11, tool is high-quality as a result because it provides the image that an external force makes scanning.

Base 2 the place aheads are provided with a light source 23, in order to provide when scanning required light, base 2 tops are an optical mechanism 1, a fulcrum 15 that is provided with between this optical mechanism 1 and the base 2 wherein, it is positioned at the position of optical mechanism 1 middle below, in order to the weight of carrying optical mechanism 1 major part, and the fulcrum when be optical mechanism 1 activity.Optical mechanism 1 tail end below is a flexible member 16, it not only can share optical mechanism 1 weight partly, and can provide a power of upwards replacing, when optical mechanism 1 front end being lifted when slide or because of anchor clamps thickness with thickness, provide optical mechanism 1 tail end downward space, thus, optical mechanism 1 is just just like seesaw, utilize lever principle to do the rotation of a little, reach the purpose that adapts to other elements and keep high precision, if when cooperating, also can scan the slide of different-thickness with different slide fixed cell.

The utility model makes optical mechanism 1 keep contacting to obtain a high-quality scan-image with the slide fixed cell owing to used the method for moment of elasticity.If do not use the method for moment of elasticity, the relative position between lantern slide and eyeglass can make that the focusing effect of scan-image is relatively poor.

This optical mechanism 1 can pass through a clip, screw, bolt, screw or other jockeys, to install or to connect this fulcrum 15, makes optical mechanism 1 can shake or move forward and backward on fulcrum 15, and its flexible application that is based on flexible member 16 is shaken it or moved forward and backward.

When optical mechanism 1 is not done scanning motion, park on skating-aid board 18, when scanning motion begins, promptly slide on the slide fixed cell, this slide fixed cell wherein only must have and bear the element that optical mechanism 1 slides the application of force and get final product; Slide guide bar 11 then is the chevron of two of one group of tools, and the structure that the centre can allow light path pass through only has the tip 111 of chevron to contact with skating-aid board 18 or slide fixed cell when optical mechanism 1 is parked and slided.This slide guide bar 11 is polishing, minimizes so the friction that can be produced sliding shakes, and does not influence the function of scanning.

See also Fig. 2 A, it is one of them method of moment of elasticity, and in other embodiment of the present utility model, the position of this flexible member 16 is variable, for example: see also Fig. 6 A, there is shown the position of the moment of elasticity of this scanning means.

In Fig. 6 A, this fulcrum 15 is positioned at optical mechanism 1 end, and this flexible member 16 is positioned in the middle of slide guide bar 11 and the fulcrum 15, and this moment of elasticity has above-mentioned identical functions.

Consult Fig. 6 B again, it is the method for another kind of moment of elasticity, and this flexible member 16 and fulcrum 15 are positioned at the top of optical mechanism 1, and the method for this moment of elasticity has above-mentioned identical functions.

The method of other forms of moment of elasticity also can be applicable among other embodiment of the present utility model, no matter flexible member 16 provides the elasticity of pressing or drawing, its final result provides a strength makes 11 compressings of slide guide bar contact with the slide fixed cell, to obtain high-quality scanning.

Both are relative connects with optical mechanism 1 and light source 23 for the method for using moment of elasticity, and these both connections are arranged in a straight line when scanning.Therefore, when the scanning lantern slide, light source 23 and this slide maintain tram each other, obtain a correct focusing, to obtain a high-quality scanning.

In this embodiment, front support leg 21 is connected in carriage or base 2 with rear leg 22, yet in other embodiment, front support leg 21 is not to be connected in carriage or base 2 with rear leg 22.

See also Fig. 7, this slide rail 3 sees through a cylinder 22B and rotates, and this cylinder 22B is not fixedly connected on this carriage or base 2 to fix the support of this light source 23, and this cylinder 22B has comprised a support, and it is by in the opening of base 2 or the support of light source 23.

This method is not because this cylinder 22B is fixed in base 2, and the support of light source can up or move down, but as long as forward or must be against base 2 when mobile backward.Because optical mechanism 1 and light source bracket are connected, no matter be optical mechanism 1 or light source bracket, its any moving all needs to make slide guide bar 11 to be connected with the slide fixed cell.Yet, optical mechanism 1 and light source 23 residing trams, and the connection being aligned all needs to keep.

See also Figure 1 and Figure 2, this slide fixed cell further includes a skating-aid board 18, this image is positioned between slide fixed cell and this skating-aid board 18 when scanning, place when image after is pinned by the slide fixed cell and to fix, this image can not move or change and can scan.

In this embodiment, the slide fixed cell also can further comprise slide fixture 17, promptly form by slide fixture 17 and skating-aid board 18, wherein slide fixture 17 is connected with skating-aid board 18 by a hinge, and it makes slide fixture 17 to open easily or to shut.Yet, in other embodiment of the present utility model, this slide fixture 17 can be combined into the box-like film case of a film with skating-aid board 18, so, the lantern slide of particular size can scan easily, promptly no matter size the size or unique size all can scan.This slide fixture 17 can not be fixedly connected on this skating-aid board 18 by the hank chain yet, but this position is buckled in absolute demand.

The applied principle of the utility model sees also shown in Fig. 2 A, and right-hand point of application is the flexible member 16 among Fig. 2 among the figure, i.e. the point of application of whole lever system, and wherein this flexible member 16 can be the equivalence element that elastic plate, spring etc. have elastic force; And fulcrum is fulcrum 15, and system's left is the slide guide bar 11 of optical mechanism 1, most advanced and sophisticated 111 contacts with the slide fixed cell with it, and adapts to its variation and be lever motion.When scanning because of optical mechanism 1, slide must be placed within the spatial dimension of the predetermined scanning of optical mechanism, therefore the error of all element accumulations must be less than 1 patient scope of optical mechanism, promptly slide must be in the focal range of camera lens (focus depth, FD).

And consult Fig. 3 A, Fig. 3 B, Fig. 4 and Fig. 5, this slide fixture 17 is positioned at the top of lantern slide and fixedly makes its scanning, and lantern slide can not be moved when scanning.This slide guide bar 11 is striden the top of being located at slide fixture 17 when scanning, as above disclose, the method of moment of elasticity provides a suitable strength to make this force applications in compressing slide guide bar 11 past slide fixture 17 tops that are displaced downwardly to, and whole strength can't change when scanning.

Scope (the Focus Depth of focusing; FD) for the position of the suitable focusing in when scanning, make lantern slide F to scan in correct position, L1 be lantern slide F when scanning and the distance of eyeglass 12, L2 is the height of slide fixture 17.

Consult Fig. 3 B and Fig. 3 C, lantern slide F and slide fixture 17 are not to meet at right angles with eyeglass 12, and lantern slide F is positioned within the FD scope.

Because both are all flexible load slide fixture 17 and skating-aid board 18, and have flexual ability, when it transmits the position of a little change and can not lose whole strength, even if under these conditions, lantern slide F should still be positioned within the FD.

See also Fig. 3 A, when normal scan, whole slide F should be by slide fixed cell clamping, and be placed in the depth of focus of optical mechanism 1, penetrate manuscript from light source 23 transmissions thus, enter the light of camera lens 13 refractions, can enter imaging in the OPTICAL SENSORS 14 through minute surface 12 reflections.

When the problem of precision takes place in optical mechanism 1, during tilt condition shown in Fig. 3 B, a is the due distance of board surface distance body seat of carrying slide, a1 is the mistake distance of platform gained, the mistake distance of gained when a2 is the platform perk, and the reflecting optics 12 of optical mechanism 1 to the light path of slide F is L1.Because of a1 is short than a, slide F is short than L1 to the distance of reflecting optics 12, and the distance that optical mechanism 1 only can scan is a.

For solving the error of above-mentioned generation, shown in Fig. 3 C, scan mode of the present utility model adopts linearity to move forward into line scanning, promptly in when scanning only the slide of some be positioned at focal range and get final product, the part that slide F is not scanned need not enter focal range, therefore can make the influence that error may take place when making assembling scanning means drop to minimum.

See also Fig. 4 again, except that can be as the issuable error of above-mentioned adaline body, if use different anchor clamps or fixed cell, also can adapt to different slide F, platform with the carrying slide is an example, because in the optical mechanism 1 reflecting optics 12 to camera lens 13 front focal lengths from fixing, need be with the slide fixed cell of suitable thickness L2 during egative film in scanning, the position that can find out slide F this moment is just in the depth of focus that scan light mechanism 1 is scheduled to.

The utility model is in scanning during lantern slide, because of the edge of lantern slide has thickness, so the anchor clamps that contact with scan light mechanism in order to fixing lantern slide must be had some change, the slide of lantern slide partly could be placed in the depth of focus.Generally speaking, (being the sheet of clamping slide) about equally about the thickness of slide edge, be that 1/2nd of the edge thickness L2 that promptly accounts for is the thickness of L4, therefore the thickness L3 of the slide fixed cell that the uses thickness L4 that only needs the thickness of original slide fixed cell to deduct slide to increase gets final product, as shown in the formula:

L2-L4＝L3

This moment, the slide of visible lantern slide partly was placed in the focal range, can correctly finish scanning work.

Lever motion does not have only the model of fulcrum 15 at the point of application (being flexible member 16) and stress point (slide fixed cell), also the point of application and stress point can be placed the homonymy of fulcrum, as shown in Figure 6A; In Fig. 6 B, also the fulcrum 15 and the point of application (being flexible member 16) can be placed homonymy, stress point (slide fixed cell) then places heteropleural, i.e. the position of optical mechanism 1 below.

Because slide rail 3 passes in the hole of front support leg 21 and rear leg 22, and rear leg 22 protrudes out a cylinder 2 2B so that base 2 is fixing, wherein base 2 can move up and down along this rear leg 22, as shown in Figure 7, therefore can drive the light source 23 that is positioned at base 2 other ends does suitable displacement, further increase the convenience of adjusting on the assembly of scanning means, and can guarantee the displacement relation of inter-module.

As mentioned above, slide fixture 17 can scan in order to scanning means according to the size adjustment of lantern slide.

The button of scanning scans with driving on being positioned at scanning means, in case touch this button, motor can drive slide rail 3 to begin to slide, and when slide rail begins toward front slide, can make the support of light source and optical mechanism 1 move forward.Light source will throw light on lantern slide the inboard and see through the slide fixed cell and be fixed to scan, because the lantern slide of scanning is the lantern slide of transparent or semitransparent shape, so that scanning can see through the tip 111 in the slide guide bar 11 and can reflect from lens surface, the image of this reflection can and be caught this image via OPTICAL SENSORS 14 at last by this camera lens, at last, the electronic installation in the scanning means can store or handle the image of this seizure.

In case after scanning was finished, motor advanced or retreats, it sees through a slide rail, and the support of this light source and optical mechanism can see through this machine makes it be back to standby position, and in the device of awaiting orders, this slide guide bar 11 can stop at the end of skating-aid board.

The image of this seizure can transfer to computer via the connecting line of USB or IE1394.

The user is flexible operating or the image that further uses computer handle to catch freely.

Therefore, slide scanning means of the present utility model can be widely used in the scanning of various slidies, utilize assemblies such as fulcrum and spring can make optical mechanism do limited activity,, finish the slide scanning work of high-res so that it cooperates the requirement of high precision.

As mentioned above, see through the scanning means of the utility model lantern slide, it provides a device for image to deposit and puts a fixed position, and can not move easily or change through external force, can make this device have more permanent useful life.Again, because the relative position that light source is put is when scanning, it has appropriate configuration with respect to most advanced and sophisticated with eyeglass, produces a high-quality scan-image.Use moment of elasticity and make that the slide fixture can be adjusted easily, to obtain the suitable focusing effect of image when optical mechanism can be at the different size lantern slide.Moreover the slide fixed cell can be a film case movably, and it allows the lantern slide of different sizes, form or thickness, and all can see through the utility model effectively to scan.And the utility model includes an elastic device, and this slide guide bar is supplied with this slide guide bar of an external force pressure and moved on the slide fixture, so that produce a suitable focusing behavior when scanning.

Above-described embodiment only is explanation technological thought of the present utility model and characteristics, its purpose makes those of ordinary skills can understand content of the present utility model and is implementing according to this, when can not with qualification claim of the present utility model, promptly the equalization of doing according to design of the present utility model generally changes or modifies, and must be encompassed in the claim of the present utility model.
