Problems solved by technology

[0006] As can be seen from the above, the lens driving device 10 of a conventional camera has a complex focus positioning mechanism, and requires an electromagnetic device and a gear combination, so the complexity and component cost will increase, and this highly complex structure will increase the assembly cost. unable to lower
In addition, although the electromagnetic device can effectively achieve the function of precise positioning, it also reduces the space used in the lens driving device 10 of the camera.

Abstract

The present invention provides one camera lens and its focusing and positioning mechanism. The camera lens includes one base with one vertical circular hole, one rotary focusing lens fixed inside the circular hole, one rotary positioning wheel fixed on the base and with one horizontal ratchet edge, one smooth edge, one first end and one second end, one actuating element capable of shifting horizontally to drive the focusing lens and the positioning wheel, and one fixture including one horizontal rotating arm capable of moving on the positioning wheel and one vertical rod capable of contacting with the horizontal sides of the positioning wheel.

Description

technical field [0001] The invention provides a focus positioning mechanism, in particular a focus positioning mechanism for a camera lens. Background technique [0002] Please refer to figure 1 , figure 1 It is a top view of the lens driving device 10 of a conventional camera. The lens driving device 10 is disclosed in US Pat. No. 5,680,649, entitled "Lens Driving Device for Camera with Auto Focus Function". The lens driving device 10 includes a base 12 which includes a cylindrical vertical hole 16, a focusing lens 14 is fixed in the hole 16 in a rotatable manner, and a driving ring 40 can move along the hole 16 of the base 12. It is fixed on the base 12 in a manner of external rotation, a shutter interlocking ring 44 is fixed on the base 12 in a manner of engaging with the driving ring 40, a positioning element 42, and a lens interlocking ring 18 are based on The drive ring 40 and the positioning element 42 are fixed on the base 12 in a manner of ...
