 note = {Author intended to study the theoretical as well as the experimental analysis of motion on the Prontor type shutter, one of the three types of lens shutters, and divided the motion into three strokes the opening stroke, the full opened stroke and the shutting stroke. The equations of motion in each stroke are obtained and solved under the initial and boundary conditions of motion. The results thus obtained from the theoretical analysis are compared with those of actual experiments by the use of apparatus specially devised by the author and it becomes clear that the motion of this type shutter is in agreement with those theoretically calculated., Article, 信州大学工学部紀要 6: 47-58 (1956)},
