Optical element switching device and image recording device having same

Abstract

The present invention relates to the technical field of optical instruments, and in particular, to an optical element switching device and an image recording device having the same. The optical element switching device includes: a base where a plurality of optical elements are arranged on an end surface facing a glass window; a driving mechanism connected to the base and used for driving the baseto rotate to transport the optical elements to predetermined positions; a positioning mechanism connected to the base and having a first state in which the positioning mechanism is locked to the basewhen the optical elements rotate to the predetermined positions, and a second state in which the positioning mechanism is unlocked from the base when the driving mechanism drives the base to rotate. The invention provides the optical element switching device capable of fixing the positions of the switched optical elements so as to improve a capture effect, and an image recording device having thesame.

Description

technical field [0001] The invention relates to the technical field of optical instruments and equipment, in particular to an optical element switching device and an image recording device having the same. Background technique [0002] A camera is a device that uses the principle of optical imaging to form an image and uses a film to record the image. It is an optical device used for photography. In modern social life, there are many devices that can record images, and they all have the characteristics of cameras, such as medical imaging equipment, astronomical observation equipment, etc. [0003] At present, in order to meet the photography needs of different scenes, SLR cameras and mirrorless cameras, which are high-end photography needs, need to be equipped with lenses of different focal lengths. Although good shooting results can be obtained in this way, carrying various lenses with you will greatly increase the burden of travel. At the same time, it takes a certain am...

AI Technical Summary

Problems solved by technology

Although you can get a good shooting effect in this way, carrying various lenses with you will greatly increase the burden of travel.

At the same time, it takes a certain amount of time to change the lens, but sometimes the opportunity to shoot is fleeting, and the best time to shoot after the lens change is completed has been missed, leaving only regret

However, portable small cameras are currently fixed with a lens on the body, which cannot be replaced. Although it is convenient to carry, when encountering different shooting scene requirements in the actual use process, it is difficult to a...
