Abstract
The utility model relates to an optical path reflecting lens fixing structure for a scanner; two ends of a scanning head rack (1) are respectively emitted with a bearing face (3) corresponding to a reflecting lens (2). The utility model is characterized in that the opposite faces of the bearing faces (3) are respectively emitted with a clamping face (4) which forms a U shape faucet with the corresponding bearing face (3); the width of the faucet is bigger than the thickness of the reflecting lens; and the two ends of the reflecting lens are respectively inserted into the U shape faucets, wherein, an elastic top pressing structure is arranged between each clamping face (4) and the reflecting lens (2). The elastic top pressing structure adopts elastic cushion, such as rubber cushion (5); and the manner has best effect. In the past, the fixing of the reflecting lens by clamping card is to utilize the rigidity of the clamping card to tightly clamp the lens on the scanning head rack; the fixing manner is firm and wearable, but is not convenient to be operated, and the clamping is not in place, the cost is high, and the lens is easy to deform for a long time. After being improved, the U shape emitting faucets and the elastic top pressing structures are used for fixing, thereby increasing the tenacity so as to make the lens be uneasy to breach with better vibration resisting performance; furthermore, the tenacity of the rubber cushion makes the lens be uneasy to deform.
Description
Technical field
The utility model relates to a kind of scanner, particularly a kind of fixed form of the reflecting optics in the scanner head light path.Described reflecting optics specifically refers to rise in the light path eyeglass of reflex, to play the lens wearer of perspective effect in the difference light path.
Background technology
Scanner is when carrying out scan task, and scanner head moves along certain guide frame and finishes swash width, cooperates with the optical image device by certain light path with this to convert picture or manuscript to computer graphics metafile.Above-mentioned light path except camera lens and mainly constitute by one group of reflecting optics, these reflecting optics utilize the optical reflection principle will scan the image that obtains by certain light path arrangement and send in the camera lens.For position and the angle of each reflecting optics of accuracy in light path that guarantee light path is vital.In the prior art, reflecting optics is all formed by a transparent glass sheet coating reflection horizon, penetrating on the relevant position of scanner head support body (chassis) has breasting face (or claiming locating surface), the two ends of reflecting optics all are to adopt special-purpose metal mounting board (clip) clip to be fixed on the breasting face, with this reflecting optics are fixed.Though such fixed form effect is pretty good, exists shortcoming to be: 1, mounting board (clip) is generally made by the specific alloy material, and cost is higher; 2, mounting board (clip) is to utilize rigidity catoptron being stuck on the scanner head support body (chassis) tightly, although fixing very firm, and reliable, and the time one makes the reflecting optics distortion for a long time easily; 3, assembly manipulation inconvenience, and often block not in placely, cause location inaccurate or eyeglass distortion; 4, owing to be the rigidity crimping between mounting board and the eyeglass, the eyeglass phenomenon of rupture often appears in product when impacting and falling environmental test, has only the glass for lenses thickening in order to overcome this phenomenon in the past, and sticks the vibrationproof double sticky tape in back lens surface.Along with scientific and technological progress, resemble this class business automation equipment of scanner just towards ultrathin and miniaturization development, above-mentioned defective is more or less brought some unfavorable factors, for this reason, the utility model is from improving the angle of structure, designed a kind of simple and practically, the reflecting optics fixed sturcture of better effects if is to overcome above-mentioned deficiency.
Summary of the invention
For achieving the above object, the technical solution adopted in the utility model is: a kind of scanner light path reflecting optics fixed sturcture, on the corresponding reflecting optics end positions of scanner head support body, penetrate a breasting face respectively, a clamping face is penetrated on opposite at breasting face simultaneously, form a U-shaped socket between this clamping face and the breasting face, the socket width is greater than reflecting optics thickness, and insert respectively in the U-shaped socket at the reflecting optics two ends, wherein is provided with the elastic top laminated structure between clamping face and the reflecting optics.
Related content and change interpretation in the technique scheme are as follows:
1, described " scanner head support body " is meant and removes remaining support outside camera lens, reflecting optics and the photoelectrical coupler part in the scanner head, also claims bare headed frame or bare headed monomer, English cry " chassis ".Described " ejaculation " is meant by the extended structure of one injection moulding.Described " breasting face " is meant the meaning of locating surface, and reflecting optics is exactly to rely on the location of this locating surface to guarantee position and the angle of eyeglass in light path when the location, and this breasting face is made of the face territory of penetrating on the scanner head support body.Described " clamping face " has been meant the face territory of the effect of gripping, and this face does not generally play the role of positioning.
2, described " the socket width is greater than reflecting optics thickness " is still gapped behind the requirement reflecting optics insertion U-shaped socket, otherwise just requiring provides elastic force to fix between breasting face and the clamping face, do the material requirements of scanner head support body too high like this, may cause cost to increase, the size of elastic force also is difficult to grasp in addition, can make problem become complicated.Reflecting optics residing position and angle in light path are that position and the angle by the U-shaped socket guarantees.
3, in the technique scheme, described elastic top laminated structure can have following two kinds of forms:
(1), the elastic top laminated structure directly adopts cushion.Fix eyeglass by between clamping face and reflecting optics, inserting cushion during assembling.This structure is very simple, and effect is fine, and assembling and demolition are all very convenient.Described cushion is specifically as follows rubber gasket, also can be soft pad, such as scraps of paper etc.
(2), the elastic top laminated structure adopts the spring bulge-structure, this spring bulge-structure is made up of spring and roof pressure piece at least, the residing clamp structure of clamping face is provided with hole or groove, and spring and roof pressure piece place hole or groove, and its roof pressure piece stretches out from hole slot and acts on the reflecting optics.This mode structure is complicated, but still feasible, and effect is better.Described " hole or groove " is meant it can is pore structure or groove structure.
The utility model principle of work is: penetrate the U-shaped socket of reflecting optics on the scanner head support body, carry out roof pressing type by the elastic top laminated structure between clamping face and reflecting optics and fix.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, to adopt mounting board fixation reflex eyeglass be the rigidity of utilizing mounting board in the past eyeglass being stuck on the scanner head support body tightly, though this fixed form is very firm, and also durable, but inconvenient operation, and often block not in placely, cost is higher, and the time one also can make eyeglass produce distortion for a long time.The improvement back adopts U-shaped to penetrate socket and the elastic top laminated structure fixes, and has increased toughness, makes eyeglass be not easy to break, and shock resistance is better, and because the toughness of rubber gasket itself makes eyeglass be not easy to produce distortion.
2, because U-shaped outlet structure described in the utility model is to be finished by the injection moulding of scanner head support body one, if it is lower to adopt the rubber gasket inserted mode to fix the reflecting optics cost.
3, dress folding eyeglass is all very convenient, and can guarantee that eyeglass accurately locatees.
