The object of the invention and solve its technical matters and also can adopt following technical measures further to realize.
Aforesaid lens assembly, wherein said stationary magazine creel has a track, and said rotating cylinder can be followed this track rotation and moved axially.
Aforesaid lens assembly, wherein said rotating cylinder comprises a projective structure, and when this rotating cylinder was positioned at an ad-hoc location, this projective structure can move into the detecting position of this sensor, so as to detecting the position of this rotating cylinder.
Aforesaid lens assembly, wherein said projective structure are a sheet structure.
Aforesaid lens assembly, the bottom of contiguous this stationary magazine creel of wherein said ad-hoc location.
Aforesaid lens assembly, wherein said survey device is arranged at the madial wall of this stationary magazine creel, and the detecting position of this sensor is towards this rotating cylinder.
Aforesaid lens assembly also comprises a pedestal, and this pedestal is arranged at the bottom of this stationary magazine creel, and this pedestal can be fixed this sensor.
Aforesaid lens assembly, wherein said sensor are interrupter-type detectors.
Aforesaid lens assembly, wherein said sensor are reflective detectors.
The present invention compared with prior art has tangible advantage and beneficial effect.Know that by above for achieving the above object, the invention provides a kind of lens assembly, this lens assembly comprises a stationary magazine creel, a rotating cylinder and a sensor.Rotating cylinder is sheathed on the inboard of stationary magazine creel, and sensor is arranged at the inboard of stationary magazine creel, in order to the position of detecting rotating cylinder.By technique scheme, lens assembly of the present invention has advantage and beneficial effect at least: lens assembly does not produce unnecessary volume because sensor is set, and therefore, lens assembly can have smaller volume, applicable to small-sized digital product.
In sum, lens assembly of the present invention, rotating cylinder are sheathed on the inboard of stationary magazine creel, and sensor is arranged at the inboard of stationary magazine creel, do not have to produce because sensor is set unnecessary volume.The present invention has obvious improvement technically, and has tangible good effect, really is the new design of a novelty, progress, practicality.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention; Understand technological means of the present invention in order can more to know; And can implement according to the content of instructions, and for let of the present invention above-mentioned with other purposes, feature and advantage can be more obviously understandable, below special act preferred embodiment; And conjunction with figs., specify as follows.
