Description
Technical field
The utility model is related to camera lens field more particularly to a kind of DV camera lenses of lens barrier opening and closing reliable.
Background technology
DV camera lenses are made of multi-disc eyeglass, and material is then divided into glass and two class of plastics.Many test report are all shown at present,
The lens of glass might not can bring clearer image than plastic material, while glass lens may also increase camera weight
Amount.The lens assembly is made of successively lens, electronic shutter, lens group 1, lens group 2 and CCD from right to left, the shadow of shooting
As being exactly to be incident upon on CCD to be imaged along this light path.Focus adjusting system and shutter system in component are by lens group 1
It is formed with electronic shutter, the two is connected together.Under the drive of motor, lens group 1 and electronic shutter front and rear can move
It is dynamic, focus adjustment is carried out, so as to obtain most clearly image, is controlled and exposed by electronic shutter.Multiple lens be complete optics into
As, and optical signal can be converted to electric signal by last CCD.
Number of patent application is that the utility model patent of CN201220149060.6 discloses a kind of DV camera lens frame, is wrapped
It includes body, camera lens, camera shooting display screen, battery and holds set, the front end of the body sets camera lens frame, the camera lens
Frame is equipped with lens barrier and for controlling the lens barrier button that lens barrier switchs, the lens barrier and lens barrier
Button is connected；Lens barrier closing and open function are controlled using lens barrier button, changes traditional window curtain type and pulls on
The mode opened is closed and released, makes more easily to operate in shooting process, more meets the needs of consumers in general, carry simultaneously
The high market competitiveness.
But the baffle on above-mentioned camera lens frame operates only by button, it is unreliable to open and close.When opening lens barrier, nothing
Method ensures that baffle is opened completely, so as to ensure that camera lens can obtain scene.When closing lens barrier, it can not ensure that baffle is complete
Contract fully, so as to, possibly into dust, cause picture unintelligible on camera lens.When lens barrier cannot be closed reliably, the light of camera lens
It learns element to be easily damaged, influences the use of DV.
Utility model content
