In another embodiment, optical base 11 is only organized and is provided with lens 21 and gets final product, and can not need group to be provided with any catoptron.For example the lens 21 of optical base 11 can directly receive the image information of corresponding scanning document, and perhaps optical base 11 can be separated or the like with reflector group.
This adjustment plate 31 is located at second side 14 of this optical base 11 with adjustable mode group, and should adjust plate 31 correspondences and this lens 21.This image sensing component is located on this circuit board 42 for 41 groups.This circuit board 42 is located on this adjustment plate 31 with adjustable mode group, and the image sensing component on it 41 is relative with these lens 21.
Fig. 2 is one of outside drawing of adjusting plate.Disclose the L shaped lamellar body that this adjustment plate 31 is formed in one among the figure, include the transverse part that is constituted by one first lamellar body 32, reach the vertical portion that is constituted by one second lamellar body 33.Winding place of above-mentioned two lamellar bodies constitutes a junction 34.Offer two elongated slots 39 on this connecting portion 34, be under pressure and bend distortion in order to this two lamellar body, but under the collocation of design conditions, can also omit this two elongated slot 39, or reduce or increase the quantity of elongated slot 39.Be formed with two slotted holes 37 on this first lamellar body 32.And also be formed with two slotted holes 43 on the circuit board 42.
Fig. 3 is two of the outside drawing of adjusting plate.The surface of this second lamellar body 33 is provided with the projection 36 of tool screw 38.For example the fixation kit (not shown) of screw is passed the slotted hole 43 of the circuit board 42 of Fig. 2, and circuit board 42 is locked on second lamellar body 33.Before locking, this circuit board 42 just relatively this second lamellar body 33 move up and down, or swing an angle.
This image sensing component 41 is installed on this second lamellar body 33, and relative with these lens 21.
Fig. 4 is for adjusting action diagram one.Because this adjustment plate 31 is locked on this optical base 11 with first lamellar body 32, and this first lamellar body 32 offers slotted hole 37 and establishes for locked assembly (not shown) lock, therefore do not break away under the condition of locking position at slotted hole 37, can move forward and backward (as shown by arrows) this adjustment plate 31, also can adjust this adjustment plate 31 so that its swing angle (shown in dotted line).Via above adjustment, group is located at the image sensing component 41 of adjusting plate 31 just can have preliminary adjustment effect.
Fig. 5 is for adjusting action diagram two.Because this second lamellar body 33 and this circuit board 42 can relative displacement and relative swings, so can circuit board 42 be moved up and down (direction as shown by arrows), or swing an angle (shown in dotted line) under second lamellar body, 33 fixed situations.Via above adjustment, the circuit board 42 that group is located on second lamellar body 33 of adjusting plate 31 can obtain further to adjust effect with image sensing component 41.
Fig. 6 is for adjusting action three.Because the connecting portion 34 of this second lamellar body 33 and first lamellar body 32 has the ability of plastic yield, thus can when adjusting the position, bestow the acting force of pushing to this second lamellar body 33 or circuit board 42, and make it form plastic yield.Thus, organized the image sensing component 41 that is located on this circuit board 42 and can be obtained a displacement and a skewness variable quantity in view of the above.Via above adjustment action, this image sensing component can obtain and further adjust effect.By the adjustment mode of plastic yield, the adjustment personnel can make things convenient for and promptly carry out meticulous adjustment.
Adjust personnel's work for convenience, following examples can promote that the adjustment personnel are quicker optical facilities are adjusted.
