On the Vario type shutter which is a type of the lens shutters, 1 ana-lysed the motion of its mechanism, theoretically and experimentally. And I proposed the deta to design and making of this type shutter. Namely, 1 parted the motion into 4 strokes: 1. preliminary stroke. 2. opening stroke. 3. full opened stroke. shutting stroke. Then, I made the equations of the motion in each strokes, and solved them only calculation without friction loss, by moment of inertia, spring constant of parts, and the initial and boundary condition of the motions. I compared the above-mentioned result with the photographic record, was gotten by the ray passed through the shutter in real condition.
