Description
- This application incorporates by reference Taiwanese application Serial No. 089212578, Filed Jul. 20, 2000.
- 1. Field of the Invention
- The invention relates in general to a mechanism for ejecting stylus, and more particularly to the mechanism for ejecting stylus used in hand-held computers.
- 2. Description of the Related Art
- Recently, the hand-held computer such as Personal Digital Assistant (PDA), which originated from the electronic secretary of the businessman, plays an important role in daily life. It acts as a small functional computer due to its delicate exterior and artificial intelligence (AI), and is capable of recording addresses, telephone numbers, appointments, and weekly schedule of work/homework. Furthermore, the PDA is also able to receive/send email and download/transmit data by taking advantage of the thriving Internet.
- The PDA is convenient to us due to its several advantages; for example, it not only record and classify thousands of telephone numbers, but also help us to arrange weekly and/or daily schedules. With its small size, it can be placed into pockets, wallets, or handbags, and is easily accessed whenever needed. In addition, the special interface of the PDA, such as a touch screen and stylus make it more convenient to use.
- Conventionally, the stylus of the hand-held computer is retained by friction of contact. If the stylus is needed, the friction of contact must be overcome before it is taken out and one end of stylus must be held by finger. This is very inconvenient and time consuming. The traditional ejecting apparatus, however, requires too large a space to meet the requirements of hand-held computers in terms of size and weight and so not applicable to the hand-held computer.
- It is therefore an object of the invention to provide a mechanism for ejecting the stylus used in the hand-held computers. The stylus is retained by a latching mechanism, and ejected due to the recovery force of spring.
- The invention achieves the above-identified objects by providing a mechanism for ejecting the stylus. The mechanism includes a locking apparatus and an ejecting apparatus. The locking apparatus and the ejecting apparatus are separately located at opposite ends of the slide groove, and the distance between these two apparatus is equal to the length of stylus. The locking apparatus is designed according to the theory of latching mechanism to achieve the retention of the stylus. When the stylus is inserted into the slide groove of the PDA, the movable arm of the locking apparatus exactly hooks the rabbet of the stylus resulting in the fixation of the stylus. If the stylus is needed, the release bottom is pressed resulting in the movable arm being removed from the rabbet, and the stylus is then ejected along the slide groove due to the recovery force of spring of the ejecting apparatus.
- Other objects, features, and advantages of the invention will become apparent from the following detailed description of the preferred but non-limiting embodiments. The description is made with reference to the accompanying drawings in which:
- FIG. 1 illustrates a decomposed 3-D diagram of the mechanism for ejecting stylus according to the invention; and
- FIG. 2 illustrates an operating diagram of the mechanism for ejecting the stylus according to the invention.
- Referring to FIG. 1, in which a decomposed 3-D diagram of the mechanism for ejecting stylus according to the invention is presented. FIG. 1 is illustrated from a view of the inner side of
housing 114 of the hand-held computer. The mechanism for ejecting the stylus includes thelocking apparatus 10 and the ejectingapparatus 20. Thestylus 100 is inserted into theslide groove 116. Theslide groove 116 and thecompress groove 118 are located at thehousing 114 and the distance between theslide groove 116 and compressgroove 118 is exactly equal to the length ofstylus 100. With this unique design, the mechanism for ejecting the stylus only requires a small space, and the free space present in the hand-held computer is large enough to contain the entire mechanism. Hence, the present invention is very suitable for the hand-held computer. - The
locking apparatus 10 is connected to the printed circuit board (not shown in FIG. 1), and thestylus 100 is retained by a latching mechanism. Thelocking apparatus 10 includes thelock element 102, thelock holder 104, and thelock spring 106. Thepivot 202 on thelock holder 104 is able to support thelock element 102 while thelock spring 106 is placed between thereof. The ejectingapparatus 20 includes theeject cap 108, ejectspring 110, andeject holder 112. Theeject holder 112 covers the inner side of thehousing 114 and forms a hollow area, thecompress groove 118, which contains theeject cap 108 and ejectspring 110. Theeject apparatus 20 utilizes the reacting force that results from the recovery force of the compressedeject spring 110 to eject thestylus 100; therefore, thestylus 100 is pushed forward by theeject cap 108 and ejected instantly along theslide groove 116. - Referring to FIG. 2, in which an operating diagram of the mechanism for ejecting the stylus according to the invention is illustrated. The
locking apparatus 10 of the mechanism for ejecting the stylus further includes therelease button 200 and themovable arm 204, as shown in FIG. 2. When thestylus 100 is inserted into theslide groove 116, themovable arm 204 exactly hooks therabbet 206 of thestylus 100 resulting in the retention of stylus. Meanwhile, the force balance is attained resulting from the equilibrium of the upward force of theeject spring 110 due to the elastic recovery and the downward force of thestylus 100 due to the latching mechanism. - If the
stylus 100 is needed, presses therelease button 200 by anexternal force 210 so that thelock element 102 rotating clockwise while thepivot 202 on thelock holder 104 is used as a revolving spindle. Thelock element 102 is able to pull themovable arm 204 away from therabbet 206 of thestylus 100. At the same time, the downward force acting on theeject cap 108 disappears, and the recovery force of theeject spring 110 pushes theeject cap 108 upward along thecompress groove 118. Therefore, thepen point 208 is indirectly removed from thecompress groove 118, and thestylus 100 is ejected upward along theslide groove 116. Additionally, the tensile stress due to the recovery force of thelock spring 106 is able to rotate thelock element 102 back to the original orientation after themovable arm 204 is removed from therabbet 206. - According to the invention, the mechanism for ejecting the stylus used in the hand-held computer provides a convenient method of retention with a latching mechanism as well as ejection with the recovery force of the spring; hence, the stylus is easily stored and removed. Besides, the simple structure of the invention occupies so small a space that the present hand-held computers can satisfy the need without extra construction for appearance.
- While the invention has been described by way of example and in terms of the preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiment. To the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
