Focal length regulating mechanism and photographic apparatus having same

Abstract

The invention discloses a focal length regulating mechanism and a photographic apparatus having the same. The focal length regulating mechanism of the invention is arranged in the photographic apparatus and regulates the focal length of a camera lens set of the photographic apparatus. The focal length regulating mechanism comprises a focal length regulating knob which is combined with a shell of the photographic apparatus and provided with a contact part, and a pressure sensing module which is arranged at the position corresponding to the focal length regulating knob in the photographic apparatus, is contacted with the contact part and is electrically coupled with the camera lens set. When the focal length regulating knob is pressed, the pressure sensing module can generate different signal values according to the pressing quantity so as to determine the focal length of the camera lens set according to the different signal values. Besides, the invention also provides a photographic apparatus having the focal length regulating mechanism.

Description

technical field [0001] The invention relates to a photographic device and a focus adjustment mechanism. Background technique [0002] In the prior art, there are photographic devices (such as digital cameras) with a focus adjustment mechanism, and users can adjust the focus by pressing a focus adjustment button. For example, when the focus button is pressed, the lens group of the camera device will expand and contract in a desired manner, so as to facilitate the user to take pictures. [0003] In the focus adjustment mechanism in the prior art, usually two adjacent and independently arranged focus adjustment buttons are used to achieve the purpose of zooming. One of them is a zoom in button, which is usually pressed and the lens group will stretch out, so that the scene displayed on the viewfinder (such as a screen) is enlarged; and the other is a zoom out button, which is usually pressed This button will retract the lens group inward, making the scene displayed in the vie...

AI Technical Summary

Problems solved by technology

[0004] However, since the camera device originally has many function buttons, if two focus adjustment buttons are provided for the single function of adjusting the focus, it will inevitably affect other available spaces of the camera device.

Moreover, the more function buttons are set, the cost of its components will be relatively increased

[0005] In addition, in the prior art, since two focus adjustment buttons must be used together, the user must remember the difference between the two, that is, the user must remember which is the zoom button and which is the zoom button. zoom out button), otherwise it will cause confusion and make it impossible to operate the camera device smoothly
