Specific embodiment
To reach above-mentioned purpose and effect, technological means and construction used by the utility model, hereby draw with regard to this practicality
New its feature of preferred embodiment elaborate and function are as follows, are understood completely with sharp.
The operation principle of camera：Scenery is projected by the optical imagery that camera lens generates in image sensor surface, so
After switch to electric signal, by A/D（Digital-to-analogue conversion）Become data image signal after conversion, be then sent through in digital signal processing chip
Working process, then be transferred in computer and handled by USB interface, by display it is seen that image.
It please refers to Fig.1 to shown in Fig. 5, the utility model discloses the fixed knot of a kind of cam lens and imaging sensor
Structure, 2 and one lens fixed seat 1 of pcb board for being equipped with imaging sensor 23 including one, the lens fixed seat 1 are cuboid,
Wherein square is optimal selection, and 1 top of lens fixed seat has a through hole 13, and imaging sensor 23 is to being located at through hole
13,2 plate face of pcb board for being equiped with imaging sensor 23 is set towards 1 inside of lens fixed seat, the lens fixed seat 1
Inside is equipped with two pillars 11, and two pillars 11 are symmetrically disposed on the both sides at 1 center of lens fixed seat, and in the present embodiment, two is convex
Column 11 is respectively arranged at exemplified by a pair of of linea angulata both ends of 1 inside of lens fixed seat, and two pillars 11 can also be set respectively
Opposite both sides other positions, the pcb board 2 correspond to a wherein pillar 11 and are equipped with circle in 1 inside of lens fixed seat
