Liang Shang, rotates and under the hinge effect of door frame at connecting rod, and the beat finally realizing flipbook arm rotates, and completes automatic page turning important
Step.
This programme uses multiple dynamical system to coordinate corresponding pushing mechanism, it is possible to control the flip angle of flipbook arm
System, realizes automatic page turning when books archives scan, is greatly improved its safety and page turning efficiency.
