Abstract
The utility model relates to a contact type image sensor, which comprises a frame, wherein a light source is positioned above the frame, the middle of the frame is provided with a lens, a base plate is positioned under the frame, and the base plate is provided with a sensor; and the contact type image sensor is characterized in that the frame is shaped by casting PC plastics with good electric conduction, the corners of the frame are embedded with cropper nuts with good electric conduction, and grounding guide lines are connected with the cropper nuts by bolts. As the frame is made from the PC plastics with good electric conduction and is connected to the ground through the cropper nuts and bolts with good electric conduction, the static electricity which is generated by the friction between a paper tooth and a paper is discharged from the frame, the nuts and the bolts, and the frame does not generate the phenomenon of the accumulation of the static electricity to eliminate the damage caused by the static electricity. The contact type image sensor has the advantages of simple structure, good static electricity removing effect, reliable work, good image transmission quality, hard damage and long service life, and the like, and is suitable for various contact type image sensors.
Description
Technical field:
The utility model relates to image reading apparatus, says it is a kind of contact-type image sensor of antistatic in detail.
Background technology:
We know, contact-type image sensor is by framework, light source, lens and transducer are formed, continuous expansion along with the contact-type image sensor range of application, its function and performance also constantly increase and improve, to lead the paper effect and lead the chart speed degree in order to increase, the paper tooth is led in having increased on framework of having now, to match with outer end equipment, lead paper tooth and paper constantly friction can produce static, because existing framework does not possess conductivity, fricative static constantly runs up on the framework, in addition, along with market is more and more higher to the requirement of sweep speed, paper is also more and more faster in the translational speed of leading the paper tooth surface, and the fast more accumulation of static electricity of speed must be many more, and the harm of static is well-known, it not only influences the normal of paper moves, and makes the paper adhesion and causes and wander off; When accumulation of static electricity arrives to a certain degree, can cause electric discharge phenomena, discharge can cause the damage of sensitization IC or other electronic unit; Simultaneously, static can make dust be adsorbed on the glass surface, has had a strong impact on picture quality.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of contact-type image sensor that can effectively solve accumulation of static electricity on the framework is provided.
The utility model can reach by following measure:
A kind of contact-type image sensor, comprise framework, the framework top is provided with light source, the framework middle part is provided with lens, the framework below is provided with substrate, and substrate is provided with transducer, it is characterized in that framework adopts the good PC plastics die cast of conduction, be embedded with the good copper nut of conduction on the corner of framework, earth lead is connected with copper nut through screw.
The utility model is because framework adopts the good PC plastic material of electric conductivity to make, and be connected with earth lead by the good copper nut of electric conductivity, screw, make lead paper tooth and paper constantly the static that produced of friction in time discharge through framework, nut, earth lead, make on the framework and can not produce the accumulation of static electricity phenomenon, the harm that static brought has also just been eliminated, have simple in structure, destatic advantages such as effective, reliable operation, images quality are good, not fragile, long service life, be applicable to various contact image sensors.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A profile of Fig. 1.
Mark among the figure: framework 1. lens 2, light source 3. glass 4, lead paper tooth 5, transducer 6, substrate 7, copper nut 8. screw 9. terminal 10, earth connection 11.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
As shown in drawings, a kind of contact-type image sensor, comprise framework 1, framework 1 is provided with glass 4, lead paper tooth 5, framework 1 top is provided with light source 3, framework 1 middle part is provided with lens 2, framework 1 below is provided with substrate 7, substrate 7 is provided with transducer 6, the structure of above-mentioned each parts and interconnected relationship applied for our company that multinomial patent was identical in 2007, this does not give unnecessary details, the framework 1 that is characterised in that of the present utility model adopts the good PC plastics die cast of conduction, be embedded with the good copper nut 8 of conduction on the corner of framework 1, earth lead 11 is through terminal 10, screw 9 is connected with copper nut 8, terminal 10 can guarantee the compactness that earth lead is connected with screw, improve conductive effect, the utility model is because framework adopts the good PC plastic material of electric conductivity to make, and by the good copper nut of electric conductivity, screw is connected with earth lead, make lead paper tooth and paper constantly the static that produced of friction in time through framework, nut, earth lead is discharged, make on the framework and can not produce the accumulation of static electricity phenomenon, the harm that static brought has also just been eliminated, have simple in structure, destatic effective, reliable operation, the images quality is good, not fragile, advantages such as long service life are applicable to various contact image sensors.
