Abstract

The invention provides a shutter and an imaging device. The shutter comprises a first mounting plate, a synchronizing ring, multiple first blades and multiple driving devices. A shutter opening is provided on the first mounting plate, and a plurality of the first blades is arranged around the shutter opening.Each of the first blades is rotatably connected with the first mounting plate. The drivingdevices are arranged around the shutter opening, and each of the driving devices is drivingly connected with the synchronization ring. The synchronizing ring is drivingly connected with each of the first blades. Each driving device drives the synchronizing ring to drive at the same time, and then drives each first blade to rotate, so as 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 the overall output of the driving device is strengthened, thereby increasing the torque of the synchronization ring. The rotation speed of the synchronization ring and the first blades is increased, and finally speed of opening and closing of the shutter is increased.

Description

Technical field[0001]The embodiment of the present invention relates to imaging device technology, and in particular to a shutter and 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 needs a corresponding driving device to complete its opening and closing, and the driving device is usually installed outside the shutter opening.[0004]However, the space outside the shutter opening is limited, which limits the number and size of the driving devices, which easily leads to insufficient driving force and slow opening and closing speed of the shutter.Summary of the invention[0005]In order to overcome the above-mentioned defects in the prior art, the purpose of the present invention is to provide a shutter and imaging device. The present invention can...
