Title:
信号発生装置
Document Type and Number:
Japanese Patent JP5411359
Kind Code:
B2
Abstract:
Disclosed is a signal generation device for use in a system for inputting information using an ultrasonic signal. The present invention has a unique design for naturally supporting the tip portion of a pen without requiring a separate configuration such as a retainer, by having a cross- sectional area (diameter) at a certain section of the pen tip which is different from the cross-sectional area of the remaining sections such that the remaining sections are held by the interior sides of the housing or the cap portion. Pen tips according to the prior art require retainers which gradually loose elasticity after long-term use which lead to decline of the ability to support the pen tip. In contrast, the present invention is able to support the tip of the pen in a stable manner irrespective of long-tern use by utilizing the unique structure of the pen tip itself which is held inside the housing.
