Slit shutter for a camera |
摘要 |
This invention is directed to a slit shutter type of photographic camera which provides one cover system which would uncover the normal camera image window and another cover system following the first in operation after a selected and suitable time delay which will cover the window again. Each of the cover systems includes a folding blind and a means to fix the blind at one end and a rigid rail means connected at the other end to form one edge of the slit. There is also means to displace the rail along a substantially straight line.
