Abstract

The invention provides a shutter and an imaging device. The shutter includes: a first mounting plate, a synchronous ring, a plurality of first blades and a plurality of driving devices, the first mounting plate is provided with a shutter opening, and the plurality of first blades A blade is arranged around the shutter opening, and each of the first blades is rotatably connected to the first mounting plate; a plurality of the driving devices are arranged around the shutter opening, and each of the driving devices is connected to the first mounting plate. The synchronous ring is in transmission connection, and the synchronous ring is respectively in transmission connection with each of the first blades. Each driving device drives the transmission of the synchronous ring at the same time, and then drives the rotation of each first blade to realize the opening or closing of the shutter opening; compared with only one driving device, the power and volume of a single driving device are reduced while strengthening the driving device The overall output, thereby increasing the torque of the synchro ring, increasing the rotation speed of the synchro ring and the first blade, and finally increasing the shutter opening and closing speed.

Description

technical field [0001] Embodiments of the present invention relate to imaging device technology, and in particular, to a shutter and an imaging device. Background technique [0002] Imaging devices such as cameras generally have a shutter, and the shutter is used to control the exposure of the imaging device. Therefore, the quality of the shutter directly affects the imaging quality of the imaging device. [0003] The shutter usually requires a corresponding driving device to complete its opening and closing, and the driving device is usually installed outside the shutter opening. [0004] However, the limited space outside the shutter opening limits the number and size of the driving devices, which easily leads to insufficient driving force and slow shutter opening and closing speeds. Contents of the invention [0005] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide a shutter and an imaging device. The ...
