摘要: Disclosed is a signal generation device for use in system inputting information using an ultrasonic signal. The present invention has unique design naturally supporting the tip portion of pen without requiring separate configuration such as retainer, by having cross- sectional area (diameter) at certain section which different from cross-sectional remaining sections that are held interior sides housing or cap portion. Pen tips according to prior art require retainers gradually loose elasticity after long-term lead decline ability support tip. In contrast, able stable manner irrespective long-tern utilizing structure itself inside housing.
