本文针对电机直接驱动式扫描机构的缺点, 设计了一种电机直驱与曲柄连杆驱动相结合的二维快速扫描机构, 该机构结构紧凑、扫描速度快, 同时可以极大降低对驱动电机的力矩要求。

To solved the problems of current motor direct driven scanners, a new design of fast optical-mechanical scanner was presented. In this design, direct drive on motor shaft was combined with crank-link mechanism. This design was compact and has a fast scanning speed. In the meantime, torque requirement for driving motor was significantly decreased.
