Embodiment Construction

[0040] The lens shifting device 10 of the present invention can be installed in such as Figure 1A Shown on projector 1. The user can adjust the member 108, for example by turning Figure 1A The rotating wheel shown makes the lens moving device 10 move so that the lens 12 can start to move. How the lens shifting device 10 achieves the purpose of moving the lens will be described in detail below.

[0041] According to a specific embodiment of the present invention, such as Figure 1BThe shown lens shifting device 10 includes a fixed base 100 , a lens mount 102 and a first actuating member 104 . The lens mounting base 102 is used for connecting the lens 12 , and the lens mounting base 102 includes a first slide rail 1020 . The lens carrier 102 is movably connected to the fixed base 100 , and the first sliding rail 1020 extends along the first extending direction FE. The first actuating member 104 includes a first end 1040 and a first connecting portion 1042 , and the first co...

Abstract

The invention discloses a lens shifting device which includes a fixed base, a lens bearing seat and an actuating component. The lens bearing seat is used for connecting a lens; the lens bearing seat includes a slide rail and is movably spliced on the fixed base, the slide rail stretches along the extension direction. The actuating component includes an end and a splicing part, the splicing part is rotatably spliced on the fixed base to limit a rotating axle to pass the splicing part, the actuating component can rotate relative to the rotating axle, and the end slides on the slide rail. When the actuating component rotates relative to the rotating axle, the end pushes the lens bearing seat to move along the direction different from the extension direction. The invention also provides a projecting camera with the lens shifting device.

Description

technical field [0001] The invention relates to a lens moving device, and in particular to a lens moving device applied to a projector. Background technique [0002] The current 3C products are progressing faster and faster, and there are technological changes every few years. Today's TVs are moving towards large size and thinness, and movies are improving towards high-resolution images and multi-channel stereo sound, in order to meet the entertainment needs of modern people. Generally speaking, projection technology is the easiest to meet the requirements of playing large-scale video images. For example, a movie theater can use projection technology to present a large image with a height of two floors. [0003] In order for the projector to correctly project the most appropriate and skew-free images, it is necessary to adjust the position and projection angle of the projector, which must be adjusted every time it is used again, which is very inconvenient to use. Therefore...
