Abstract

This invention provides a camera shutter mechanism, including: a base a diameter cam ring, a link device, a stepped motor, a shutter blade and a diameter blade. The counterclockwise rotation and clockwise rotation of the diameter cam ring control the diameter switching operation of the diameter blade and the shutter on/off operation of the shutter blade. A solenoid motor fixes the diameter. The solenoid motor also links a neutral density filter at the time of fixing the diameter so as to cause the neutral density filter to cover the aperture or leave the aperture. The shutter mechanism of the invention provides advantages of two conventional driving devices, wherein effect of electricity on the shutter precision is minimized, the speed of switching the shutter diameter is improved, the freedom for switching the shutter diameter is improved, the number of driving sources is reduced, thereby reducing a few assembly procedures, reducing assembly time and increasing product throughput.
