DEVICE FOR GENERATING THE SIGNALS USED FOR POSITION TRACING AND THE SYSTEM INCLUDING THE SAME

摘要

A position tracing signal generator and an input system including the position tracing signal generator are provided to radiate an ultrasonic signal only in the ground direction through a guide path formed between a guide and an ultrasonic signal generator to input a correct position tracing signal. A position tracing signal generator includes a main body(200) and a guide(300). The main body includes an ultrasonic signal generator(240) for generating an ultrasonic signal. The guide receives the ultrasonic signal generator such that the ultrasonic signal generated by the ultrasonic signal generator is radiated in one direction and is combined with the main body. The ultrasonic signal generator includes a plurality of ultrasonic generating units(244) which generate ultrasonic waves such that the ultrasonic waves are superposed and amplified.
