手寫筆Stylus

本發明涉及一種手寫筆，尤其係涉及一種具有按鍵手感之手寫筆。The present invention relates to a stylus, and more particularly to a stylus with a button feel.

隨著移動通訊技術之發展，觸摸屏式攜帶型電子裝置越來越受使用者之喜愛。With the development of mobile communication technologies, touch-screen portable electronic devices are increasingly favored by users.

手寫筆係觸摸屏式擕帶型電子裝置進行訊息輸入之主要方式。習知手寫筆通常為一簡單之按壓桿，使用者藉由該按壓桿直接按壓於觸摸屏式攜帶型電子裝置之觸摸屏。The stylus is the main way for the touch screen type portable electronic device to input information. The conventional stylus is usually a simple pressing lever, and the user directly presses the touch screen on the touch screen of the touch screen type electronic device.

惟，所述手寫筆使用時手感較生硬，而且還不能很好地讓使用者感知按壓之力量，如此使用者勢必會出現用力過度之現象，並對觸摸屏造成損害。However, the stylus is harder to use when used, and it does not allow the user to perceive the force of pressing, so that the user is bound to exert excessive force and damage the touch screen.

有鑒於此，有必要提供一種具有按鍵手感之手寫筆。In view of this, it is necessary to provide a stylus with a button feel.

一種手寫筆，包括一筆頭、一筆尖、一彈性元件及一筆身，該筆頭裝設於該筆身之一端，該筆尖可伸縮地容置於筆身內，且其一端露出於該筆身，該彈性元件容置於該筆身內，其一端抵持於該筆尖，另一端抵持於該筆頭。A stylus pen includes a head, a tip, an elastic element and a body, the pen head being mounted at one end of the pen body, the pen tip being telescopically received in the pen body, and one end of which is exposed to the pen body The elastic member is received in the pen body, and one end thereof abuts against the pen tip and the other end abuts against the pen tip.

相較於習知技術，所述手寫筆藉由該彈性元件之變形來使得使用者具有按鍵手感，並能感知按壓觸摸屏之強度，從而較好地改變了習知手寫筆手感生硬之缺憾。Compared with the prior art, the stylus makes the user feel the button feel by the deformation of the elastic component, and can sense the strength of pressing the touch screen, thereby better changing the shortcoming of the conventional stylus feel.

請參閱圖1所示本發明具有按鍵手感之手寫筆之較佳實施例，該手寫筆20用於進行攜帶型電子裝置訊息之輸入，其包括一筆頭21、一彈片22、一緩衝體23、一筆尖24及一筆身25。該筆尖24、緩衝體23及彈片22依次容置於筆身25內，並藉由筆頭21卡持裝設於筆身25之一端。Referring to FIG. 1 , a preferred embodiment of the stylus with a button feel of the present invention is used for inputting a message of a portable electronic device, which includes a head 21 , a spring 22 , a buffer body 23 , A tip 24 and a body 25.
