Abstract

A handheld device comprises a handheld structure and a focus following wheel assembly. The handheld structure comprises a first shell and a second shell, the first shell and the second shell are matched to form a handheld part and a mounting part, the mounting part comprises a mounting cavity, and an operation opening communicated with the mounting cavity is formed in the position, corresponding to the mounting cavity, of the first shell; the focus following wheel assembly comprises a supporting piece, a focus following plate and a focus following wheel; the supporting piece comprises a supporting seat and a mounting seat formed by extending outwards from the supporting seat, and the focus following plate and the focus following wheel are located on the two sides of the mounting seat respectively; the focus following wheel assembly is fixed in the installation cavity through a supporting piece, and the focus following wheel partially penetrates out of the operation opening. A control panel is arranged on the second shell, and a control key and / or a display screen are / is arranged on the control panel and used for operation and / or display in the focusing process.

Description

technical field [0001] The invention belongs to the technical field of control, and in particular relates to a focus wheel assembly, a handheld device and a photographing system using the focus wheel assembly. Background technique [0002] The damping control knob can be widely used in industrial machinery and digital products, such as the controllers of camera equipment in the film and television industry, such as follow focus devices, rocking wheels, and somatosensory controllers, etc., which can adjust the fine position. Good control feel. [0003] At present, there are two types of follow focus wheel structures commonly used in follow focus devices: one is the follow focus wheel module attached to the electronic device, and the independent follow focus wheel module is connected to the electronic device through the interface; the other is the follow focus wheel structure and the handle or handheld The equipment adopts an integrated design. [0004] However, the existing...
