Abstract:
A drive pulse generating apparatus suitable for a drive device generating elongation and contraction displacement by applying a drive pulse to an electromechanical transducer and driving a driven member in accordance with the generated displacement, said drive pulse generating apparatus comprising:a first timing signal generator for generating a first timing signal designating a previously set predetermined timing;a pulse generator for generating a series of pulses having a predetermined amplitude in synchronism with said first timing signal;a second timing signal generator for generating a second timing signal designating a predetermined timing determined based on information of an instructed drive speed of the designated driven member; anda controller, said controller generating a trapezoidal drive pulse for application to the electromechanical transducer by interrupting the series of pulses outputted from said pulse generator for a predetermined period of time based on said second timing signal.
