According to above-mentioned conception, fixture of the present invention, wherein this fixture is a screw.
According to above-mentioned conception, fixture of the present invention, it is used on therebetween this circuit board has a screw at least, its position be correspond respectively to had in addition on this holder one set firmly screw, set firmly screw for one and screw in and this holder and this photoelectric conversion component are formed this contact object.
According to above-mentioned conception, fixture of the present invention, its this photoelectric conversion component of using therebetween is a Charged Coupled Device.
The invention has the advantages that:
Fixture provided by the invention, be between the photoelectric conversion component and a bare engine module housing that is applied in the image scanner, it has a location datum level parallel with the photosurface of this photoelectric conversion component, by utilizing this positioning reference face to position, thereby the optical centreline of guaranteeing the photosurface of this photoelectric conversion component and this bare engine module housing is orthogonal thereto, and then can effectively avoid because the defective that floating weldering or circuit board out-of-flatness are caused.The present invention does not need to utilize and adjusts the angle rotation that latch carries out photosurface 1 and adjust, thereby when further eliminating known approaches and desiring to carry out the adjustment on Charged Coupled Device (CCD) surface, too complicated Assembly Action is to inconvenience that the assembler caused.
The present invention also will be described in further detail embodiment in conjunction with the accompanying drawings.
Description of drawings
Fig. 1 (a), 1 (b): it is the known construction schematic diagram of bare engine module in the image scanner;
Fig. 2 (a), 2 (b): it is that known construction is because of floating weldering and being the schematic diagram that printed circuit board (PCB) Charged Coupled Device that out-of-flatness causes surface and optical center line present deflection;
Fig. 3 (a), 3 (b): it is that the present invention is the organigram that improves the fixture preferred embodiment that the known approaches defective develops out;
Fig. 4 (a), 4 (b): even it is to express because float weldering or circuit board out-of-flatness, the present invention still can keep Charged Coupled Device surface and the orthogonal thereto schematic diagram of optical center line.
Wherein, description of reference numerals is as follows:
Optical facilities main body 11
Charged Coupled Device 13 printed circuit board (PCB)s 14
Fixing hole 321,322 first fixtures 34
Second fixture, 35 bare engine module housings 36

Embodiment
See also Fig. 3 (a), 3 (b), it improves the fixture preferred embodiment organigram that the known approaches defective develops out for the present invention, wherein the photoelectric conversion component of being finished with Charged Coupled Device (CCD) 31 serves as that welding is fixedly arranged on the circuit board 30 (PCB), has screw 300 on this circuit board 30, its position be correspond respectively to had on this holder 32 one set firmly screw 320, set firmly that screw screws in and this holder 32 combined with photoelectric conversion component 31 fix for one, and then form a contact object jointly.In addition, have fixing hole 321,322 on this holder 32 in addition, can insert in order to provide one first fixture 34 and second fixture 35 to screw in the screw 361,362 on the bare engine module housing 36.And these fixtures the 34, the 35th are usually finished with screw.
And major technique of the present invention is characterised in that this contact object mainly has a location datum level parallel with the photosurface 311 of this photoelectric conversion component 31, in this example, this positioning reference face is that the upper face that is designed to the elastomer 323 that had by this holder 32 is constituted, and its surface is parallel with the photosurface 311 of photoelectric conversion component 31 basically.Thus, when utilizing fixing hole 321,322 with fixture that screw is finished 34,35 and screw in screw set on the bare engine module housing 36 361,362, the positioning reference face that upper face constituted of these elastomers 323 can be close to the contact-making surface 360 of this bare engine module housing 36, and then the photosurface 311 of guaranteeing this photoelectric conversion component 31 is orthogonal thereto with the optical centreline of this bare engine module housing, and then reaches the effect of the defective of improving known approaches.
Fig. 4 (a) though be depicted as because floating weldering, make that photosurface 311 that 31 of circuit board 30 and photoelectric conversion components and fail to closely cooperate and when being crooked, apparatus of the present invention also can guarantee photoelectric conversion component 31 is orthogonal thereto with the optical centreline of this bare engine module housing and situation that do not have a deflection takes place.This is because fixing point has been transferred on the holder 32, can avoid fully crooked circuit board 30 takes place, and elastomer 323 can provide a little deformation to tolerate the crooked of 31 of circuit board 30 and photoelectric conversion components.
As for Fig. 4 (b) even then express because circuit board 30 out-of-flatnesses own, make that photosurface 311 that 31 of circuit board 30 and photoelectric conversion components and fail to closely cooperate and when being crooked, apparatus of the present invention all can guarantee photoelectric conversion component 31 is orthogonal thereto with the optical centreline of this bare engine module housing and situation that do not have a deflection takes place.Because fixing point transferred to holder 32 on, avoid the irregular circuit board 30 in plane fully.Similarly, elastomer 323 can provide a little deformation to tolerate the crooked of 31 of circuit board 30 and photoelectric conversion components.
In sum, the present invention has guaranteed the quadrature accuracy of photosurface 311 with the optical centreline of this bare engine module housing of photoelectric conversion component 31 when assembling, therefore can effectively avoid welding or the disappearance that the circuit board out-of-flatness is caused, more not need to utilize the adjustment latch to carry out the angle rotation adjustment of photosurface 311 because of floating.So can effectively solve the various defectives of known approaches, reach development main purpose of the present invention.
Though the present invention can do multiple modification by the personnel that are familiar with this technology, the scope of neither disengaging accompanying Claim institute desire protection.
