Definitions

• the present invention relates to a combined writing implement and stylus pen, and more particularly, to a writing implement having a stylus pen, which can be used as a writing implement and a stylus pen for touching a touch panel, and which has a retractable touch tip and a buffer spring, thereby protecting the touch panel while touching the touch panel .
• a Personal Digital Assistant adopts a touch panel for enlarging an LCD scr een since the size of the PDA is restricted for handheld use, and buttons of the PDA are miniaturized in size and minimized in number.
• an iron pen called “stylus pen” is used.
• a stylus pen has a problem in that a user suffers from an inconvenience of carrying another writing implement to write something since he or she cannot write something on paper with the stylus pen.

• the combined writing implement and stylus pen is easy in carrying.
• a buffer spring is provided to protect the touch panel by relieving touch pressure applied to the tou ch panel and to provide the user with a good writing feeling by evening the touch pressure. Furthermore, a preloaded spring is interposed between the nut and the slide screw in order to prevent a lateral movement of the touch tip, thereby providing the us er with better writing feeling.

• a combined writing implement and stylus pen includes: a nut 40 movable back and forth, the nut 40 being spline -coupled to a housing 32 and connected to a pen point extending and retracting member 36 of a writing implement 30 by a holder 34; a rotatable cap 42 of a hollow type connected to an end of the nut 40 in a freely rotatable fashion and in such a fashion that its axial movement is restricted; a slide screw 44 screwed with a female screw portion 40s formed on the nut 40 and spline -coupled to the rotatable cap 42; and a touch tip 46 mounted at an end of the slide screw 44, the touch tip 46 being outwardly extendable and inwardly retractable through the center of the rotatable cap 42.
• a buffer spring 80 is interposed between the housing 32 and the nut 40 in order to suck excessive pressure transferred from the touch tip 46.
• the rotatable cap 42 includes: an uneven portion 42n formed on the outer periphery thereof in order to prevent slip of the rotatable cap 42 when a user holds and rotates the rotatable cap 42 with a hand; a one -way hook portion 42h formed on the rear end thereof to be coupled with the slide screw 44, thereby simplifying an axial assembly; and a guide hole 42m for med in the center of the rotatable cap 42 for axially guiding the touch tip 46.
• the slide screw 44 includes: a male screw portion 44s formed at the rear end thereof; a spline -coupling portion 44h formed at the center thereof, for instance, having a hexagon al section, for spline -coupling with the rotatable cap 42; a boss 40a formed at an end thereof for fitting the touch tip 46 thereinto; and a holding jaw 44t formed at a portion where the male screw portion 44s and the spline -coupling portion 44h are meet with each other for restricting stroke of the slide screw 44 .
• the touch tip 46 has an annular protrusion 46b formed on the inner periphery thereof, the protrusion 46b being held and fixed to an annular groove 40b formed on the outer periphery of t he boss 40a.
• the annular groove 40b and the annular protrusion 46b simplify replacement of the worn touch tip 46.
• a preloaded spring 50 is mounted to one end of the slide screw 44 to be repelled between the nut 40 and the slide screw 44 throu gh the holder 34 in order to always apply pre-pressure to the slide screw 44 in the extending direction and prevent a lateral movement of the touch tip 46.
• the touch tip 46 may be impregnated with perfume for emitting a sweet fragrance, so that the perfume can be emitted into the air by pressure applied during the use.
• the slide screw 44 has a perfume storing chamber 72 formed therein for storing liquid perfume 70.
• the touch tip 46 is made of porous material for emitting the perfume for a long time.
• the touch tip 46 has an auxiliary pen point 64 mounted on an end thereof, so that the user can write something with the auxiliary pen point 64 and the pen point 39 mounted opposite to the auxiliary pen point 64 by turns .
• the unexplained reference numeral 31 designates a clip mounted on the housing 32 for hanging it on the user's pocket
• 90 designates the paper surface for writing
• 92 designates a touch panel
• 39 designates the pen point being extendable and retractable at the opposite side of the touch tip 46 .
• the present invention As shown in FIGS. 1 to 8 , to use the present invention as a stylus pen by extending the touch tip 46, which is hid inwardly, when the user grasps the housing 32 with one hand to prevent rotation of the housing 32 and rotates the rotatable cap 42 with the other hand in the opposite direction, the rotatable cap 42 is coupled to the nut 40 only in a rotatable condition without axial movement. So, the nut 40 is fixed to the rotatable cap 42 without movement, but the rotatable cap 42 is rotated in the opposite direction.
• the rotatable cap 42 and the nut 40 are coupled with each other only in a rotatable condition. Because the rotatable cap 42 and the slide screw 44 are spline -coupled to each other, for instance, in a hexagonal form, the slide screw 44 is rotated t ogether with the rotatable cap 42, and at the same time, moved axially in order to extend the touch tip 46 outwardly. After that, when the holding jaw 44t formed on the slide screw 44 is in contact with the end of the rotatable cap 42, the slide screw 44 c annot moved axially anymore. At this time, as shown in FIG. 6, when the user clicks icons or moves the touch tip 46 while touching the touch tip 46 onto the touch panel 92 in a state where the user holds the writing implement 30 upside down to direct the touch tip 46 in the downward direction, the present invention can be used as the stylus pen.
• the preloaded spring 50 repelled between the nut 40 and the slide screw 44 through the holder 36 is preloaded in order to always extend the slide screw 44 outwardly, so that the preloaded spring 50 can prevent the lateral movement of the slide screw 44 due to loose -fitting between the nut 40 and the slide screw 44, thereby preventing the lateral movement of the touch tip 46 and providing the user with a good writing feeling.
• the buffer spring 80 interposed between the housing 32 and the nut 40 serves to relieve excessive pressure applied to the touch tip 46 so as to prevent damage of the surface of the touch panel 92. That is, when the user con tacts the touch tip 46 with the touch panel 92 with power exceeding the repelling power of the buffer spring 80, the repelling power is transferred to the buffer spring 80 through the touch tip 46, the slide screw 44 and the nut 40, and compresses the buffer spring 80. As a result, the buffer spring 80 can prevent damage of the surface of the touch panel 92, and evening the pressure irregularly applied to the touch tip 46 during the use of the stylus pen.
• the slide screw 44 is moved inwardly in the axial direction, and the touch tip 46 mounted at the end of the slide screw 44 is retracted into the rotatable cap 42.
• the pen point 39 is extended from an end of the writing implement 30 by the pen point extending and retracting member 36 embedded in the writing implement 30, so that the user can use the present invention as the writing implement.
• the touch tip 46 is worn due to a long -term use, the worn touch tip 46 must be replaced with a new one. For this, when the user grasps the touch tip 46 extended outwardly and pulls it axially, the touch tip 46 is separated from the slide screw 44.
• auxiliary pen point 64 is mounted on the end of the touch tip 46, the user can write something with the auxiliary pen point 64 and the pen point 39 mounted opposite to the auxiliary pen point 64.
• the liquid perfume 70 is contained in the perfume storing chamber 72 formed within the slide screw 44, and the touch tip 46 is made of the porous material.
• the liquid perfume 70 stored in the perfume storing chamber 72 is gradually sucked into t he touch tip 46 by a capillary phenomenon and emitted into the air in order to emit a sweet fragrance. If pressure and friction force are applied to the touch tip 46, it facilitates emission of the perfume, so that more perfume is emitted in the air durin g the use of the writing implement.
