Problems solved by technology

[0004] However, the existing inter-mirror shutters generally have disadvantages such as complex structure, large volume, and heavy weight.
[0005] Moreover, in recent years, the size of the camera module has been gradually reduced with the development of technology, but the size of the shutter driving device has always been a major obstacle restricting the miniaturization of the size of the camera module.

Abstract

A motor (10) is applied to a shutter device (1) and a camera device with the shutter device (1), and comprises a printed circuit board assembly (12) with a winding (120), a stator core (13), a rotor (14) and a magnet (15) mounted on the rotor (14). The printed circuit board assembly (12) has a first side (121) and a second side (122). The stator core (13) is mounted on the first side (121) of theprinted circuit board assembly (12), and the winding (120) is disposed around the stator core (13). The rotor (14) and the magnet (15) are mounted on the second side (122) of the printed circuit boardassembly (12) and are spaced apart from the winding (120). The motor (10) has a flattened structure, thereby facilitating miniaturization of the shutter device (1).

Description

Technical field [0001] The embodiments of the present invention relate to the technical field of imaging equipment, and in particular to a motor, a shutter device, and an imaging device applied to a shutter device. Background technique [0002] Camera shutters usually include focal plane shutter and inter-lens shutter. A focal plane shutter is a shutter placed in front of the focal plane of imaging, usually referred to as a rolling shutter. The power released by the front curtain and the rear curtain comes from the spring and connecting rod assembly. A geared motor winds the front curtain and the rear curtain at the same time through the spring and the connecting rod assembly. The front curtain and the rear curtain each have an electromagnet. Separate control to realize the sequential action of the front curtain and the rear curtain. The focal plane shutter is mainly used in SLR cameras. [0003] The inter-lens shutter is a type of shutter placed inside the lens diaphragm, also ...
