Description

Stylus pen including a sealing member

[0001] The present invention relates to a stylus pen, and more specifically, to a sealing member capable of blocking one or more moisture ingress pathways inside a stylus pen, and a stylus pen including the same.

[0002] A stylus pen is a pen-shaped device that allows data to be entered by lightly touching the screen while dragging or clicking. Users utilize stylus pens for precise touch input.

[0003] Stylus pens can be classified into active stylus pens and passive stylus pens depending on whether they are equipped with an internal battery and electronic components.

[0004] Active stylus pens have the disadvantage that, aside from a select few advanced users, there are not many actual users because the pen itself is expensive and requires a power source to charge the battery.

[0005] Passive stylus pens have the advantages of being cheaper and not requiring a battery compared to active stylus pens, but they have the disadvantage of being difficult to achieve precise touch recognition compared to active stylus pens. However, recently, technologies for implementing passive stylus pens capable of precise touch recognition have been proposed. In particular, technologies involving resonance methods through inductive change or resonance methods through capacitive change are being proposed to implement pressure sensitivity, hovering, and button operations in LC resonance.

[0006] Conventional EMR methods are superior in writing / drawing quality, which is a core function of a stylus pen, but they have the disadvantage of being thicker and more expensive because they require the addition of a separate EMR sensor panel and an EMR driver IC in addition to a general touch sensor.

[0007] The resonance method using capacitive change is a technique that supports pen touch by enhancing IC performance without incurring additional costs, while utilizing standard touch sensors and touch controller ICs.

[0008] In stylus pens utilizing EMR or capacitive change resonance methods, the frequency of the driving signal must match the resonance frequency of the resonance circuit embedded in the pen in order for the touch sensor to more accurately identify functions (pressure, hovering) performed by the stylus pen. However, conventional EMR or capacitive change resonance methods suffer from a problem where signal transmission is difficult due to significant attenuation, even if the resonance frequency and the driving signal frequency match. Consequently, despite long-standing attempts by numerous touch controller IC vendors, no company has yet succeeded in mass production because sufficient output signals are not produced.

[0009] Therefore, in order to manufacture a stylus pen using the EMR method or the resonance method through capacitive change that can generate the maximum output signal, how to design the internal resonance circuit and the structure of the pen becomes a very important factor.

[0010] Furthermore, in EMR or capacitive resonance methods, it is important to distinguish between hover, contact, and pressure. Moreover, there is a need for stylus pens with improved performance capable of distinguishing between hover and contact even at low reference pressures.

[0011] The problem that the present invention aims to solve is to provide a sealing member capable of blocking one or more moisture inflow paths and a stylus pen including the same.

Similar reference numerals in the drawings refer to the same or similar functions across various aspects.

[0106] The overall composition of the stylus pen

[0107] FIG. 1 is a perspective view of a stylus pen (100) according to one embodiment of the present invention.

[0108] Referring to FIG. 1, a stylus pen (100) according to one embodiment of the present invention comprises a housing (101) and a core (102). The housing (101) forms the exterior of the stylus pen (100). The housing (101) has a predetermined space formed inside and has an elongated shape in one direction. The housing (101) may be formed by combining two or more parts, or it may be formed integrally as a single part.

[0109] According to one embodiment of the present invention, the housing (101) may be made of a non-conductive synthetic resin material.

[0110] The housing (101) may include a first housing (101a) and a second housing (101b). The first housing (101a) and the second housing (101b) may be combined to form the exterior of a stylus pen (100). Various parts are embedded inside the first housing (101a) and the second housing (101b).

[0111] A button portion (109) may be disposed in the housing (101). The button portion (109) may be disposed on the outer surface in the middle of the second housing (101b). The button portion (109) may be for performing a specific action of the stylus pen (100). For example, it may be a mechanical or contact button for a cancel action.

[0112] The core body (102) includes one end portion disposed outside the housing (101), and the remaining portion excluding said one end portion is disposed inside the housing (101). Here, the one end portion of the core body (102) may also be referred to as a pen tip.

[0113] A portion of one end of the core body (102) can move into the housing (101) by an external force from the outside. As the external force increases, the volume of the portion of one end of the core body (102) entering the housing (101) can increase. When the applied external force decreases, the portion of one end of the core body (102) comes back out of the housing (101) by the mechanical operation of the parts inside the housing (101). When the external force is removed, the portion of one end of the core body (102) returns to its initial state.

[0114] FIG. 2a is a drawing illustrating the internal structure of a stylus pen (100) according to one embodiment of the present invention, FIG. 2b (a) is a perspective view for explaining the structure of the inner case (110) and the cushioning member (115) shown in FIG. 2a, FIG. 2b (b) is a perspective view of only the inner case (110), FIG. 2c is a perspective view of the case where the inner case (110) shown in FIG. 2b (a) is removed, FIG. 2d (a) and (b) are perspective views of the first fixed member (130) shown in FIG. 2a and FIG. 2c viewed from various sides, FIG. 2e (a) and (b) are perspective views of the first movable member (170) shown in FIG. 2a and FIG. 2c viewed from various sides.

[0115] Referring to FIGS. 2a and 2b, the inner case (110) may have a first opening (111) in which a first protrusion (131) of a first fixing member (130) and a first protrusion (192) of a second fixing member (190) are arranged. The first opening (111) may have a base groove (111b) that extends in the longitudinal direction of the stylus pen (100), and a plurality of extension grooves (111e) that are connected to the base groove (111b) and extend in a direction perpendicular to the longitudinal direction of the base groove (111b). The plurality of extension grooves (111e) may be formed at positions corresponding to the plurality of first protrusions (131, 192). As an example, the first opening (111) may have an 'E' shape.

[0116] By rotating the inner case (110) counterclockwise or clockwise with the core body (102) as the axis of rotation, a plurality of first protrusions (131, 192) can be positioned from a plurality of extension grooves (111e) to a base groove (111b), or from a base groove (111b) to a plurality of extension grooves (111e). In particular, by positioning a plurality of first protrusions (131, 192) from a base groove (111b) to a plurality of extension grooves (111e), the first fixing member (130) and the second fixing member (190) can be fixed in position within the inner case (110). Meanwhile, since the first moving member (170) is not directly coupled to the inner case (110), it can move in conjunction with the linear reciprocating motion of the core body (102) caused by an external force between the first fixing member (130) and the second fixing member (190).

[0117] The inner case (110) may have a second opening (113) in which extension coils (125a, 125b) are placed and connection terminals (165a, 165b) are exposed. The second opening (113) provides a space for placing extension coils (125a, 125b) and can protect extension coils (125a, 125b) from external impact. Additionally, the mounting position of the connection terminals (165a, 165b) can be easily checked through the second opening (113).

[0118] The buffer member (115) may be positioned between the inductor (120) and the housing (101), and between the core (102) and the inner case (110). The buffer member (115) has a through hole through which the core (102) passes. This buffer member (115) can guide the position of the core (102), stably fix the inductor part (120), and block external electrical or magnetic influences on the inductor part (120). This buffer member (115) may be configured separately from the inner case (110), but is not limited thereto, and the buffer member (115) may be configured integrally with the inner case (110).

[0119] Referring to FIGS. 2a and 2c, a buffer member (115), an inductor part (120), a first fixed member (130), a first moving member (170), and a second fixed member (190) may be arranged sequentially along the length direction (hereinafter referred to as the 'length direction') of the stylus pen (100) from one end of the core body (102). That is, along the length direction, the inductor part (120) may be arranged on the buffer member (115), the first fixed member (130) may be arranged on the inductor part (120), the first moving member (170) may be arranged on the first fixed member (130), and the second fixed member (190) may be arranged on the first moving member (170).

[0120] The inductor section (120) includes a ferrite core (121) and a coil section (123) wound around the ferrite core (121). The ferrite core (121) has a through-hole through which a core body (102) passes. Through the through-hole, the core body (102) can move in a straight reciprocating motion along the length direction. The coil section (123) may be wound around the ferrite core (121) in at least one layer. An extension coil (125a, 125b) may be connected to each end of the coil section (123). The extension coils (125a, 125b) may be connected to coil electrodes (213a, 213b) that extend along the length direction and are respectively placed on the substrate (210).

[0121] The inductor part (120) is fixedly installed inside the housing (101). The inductor part (120) can be fixed between the first fixing member (130) and the buffer member (115) in the length direction. The inductor part (120) can be fixed by the inner case (110) in a direction perpendicular to the length direction (hereinafter referred to as the 'vertical direction').

[0122] The inductor portion (120) may be fixedly positioned on one side of the first fixed member (130). Here, a portion of the inductor portion (120) may be positioned in the second cavity (133b) of the first fixed member (130).

[0123] The inductor section (120) can be electrically connected to a capacitor section (not shown) mounted on the substrate (210) to form a resonant circuit section. The resonant frequency can be set by the inductance (L) value of the inductor section (120) and the capacitance (C) value of the capacitor section (not shown). Since the inductance (L) value of the inductor section (120) changes according to the movement of the magnetic material (140), the resonant frequency can be varied.

[0124] A capacitor section (not shown) is placed on a substrate (210). It has a preset capacitance (C) value. The capacitor section (not shown) may include two or more capacitors. At least one of the two or more capacitors may be configured as a circuit in which it is always electrically connected to an inductor section (120) as a base capacitor.

[0125] The capacitor section (not shown) includes a jumping capacitor (215). The jumping capacitor (215) is mounted on the substrate (210) and can be configured in a circuit to be electrically connected to connection terminals (165a, 165b). For example, the jumping capacitor (215) can be electrically connected to connection pads (211a, 211b) placed on the substrate (210) through conductive patterns (212a, 212b). The jumping capacitor (215) can be electrically connected to or disconnected from the base capacitor depending on the movement of the core body (102). When no external force is applied to the core body (102), the ring terminal (161) is in contact with the connection terminals (165a, 165b), so that the jumping capacitor (215) is electrically connected to the base capacitor. On the other hand, when an external force is applied to the core body (102) and the first moving member (170) that is linked to the core body (102) moves toward the first elastic member (180), the ring terminal (161) separates from the connection terminals (165a, 165b), and at this time, the jumping capacitor (215) can be electrically separated from the basic capacitor.

[0126] Referring to FIGS. 2a, 2c, and 2d, the first fixing member (130) is disposed inside the inner case (110). The first fixing member (130) has a cylindrical shape overall.

[0128] A plurality of the previously described first protrusions (131) may be arranged on the outer surface of the first fixed member (130).

[0129] A plurality of first grooves (135) may be formed on the outer surface of the first fixed member (130), each having a plurality of extension portions (171) of the first movable member (170) disposed therein. Additionally, a second groove (137) may be formed on the outer surface of the first fixed member (130) along the length direction to maintain a certain distance from the extension coils (125a, 125b) shown in FIG. 11a.

[0130] Referring to FIGS. 2a, 2c, and 2e, the first moving member (170) is positioned between the first fixed member (130) and the second fixed member (190). The first moving member (170) can move in a linear reciprocating motion between the first fixed member (130) and the second fixed member (190) in conjunction with the movement of the core body (102) in the longitudinal direction.

[0131] The first moving member (170) is disposed inside the inner case (110). The first moving member (170) has a cylindrical shape overall. The first moving member (170) has a first cavity (173a) and a second cavity (173b). A portion of the first elastic member (180) shown in FIG. 9 is disposed in the first cavity (173a), and a portion of the cover portion (150) shown in FIG. 9 is disposed in the second cavity (173b).

[0132] On the outer surface of the first moving member (170), a plurality of extension parts (171) are disposed in a plurality of first grooves (135) of the first fixed member (130). The plurality of extension parts (171) have a shape that extends along the length direction and can move along the first grooves (135) of the first fixed member (130).

[0134] FIG. 3 is a perspective view of a stylus pen (1000) according to one embodiment of the present invention, FIG. 4 is a cross-sectional view of a part of the stylus pen (1000) shown in FIG. 3, and FIG. 5 is a perspective view with the housing (1010) of the stylus pen (1000) shown in FIG. 3 removed.

[0135] Referring to FIGS. 3 to 5, the housing (1010) forms the exterior of the stylus pen (1000). The housing (1010) has a predetermined space formed inside and has an elongated shape in one direction. The housing (1010) may be formed by combining two or more parts, or it may be formed integrally as a single part.

[0136] A housing (1010) according to one embodiment of the present invention may be made of a non-conductive synthetic resin material. A button portion (1090) may be disposed in the housing (1010). The button portion (1090) may be for performing a specific operation of the stylus pen (1000). For example, it may be a button for a cancel operation or a special function operation.

[0137] The core body (1020) includes one end portion disposed outside the housing (1010), and the remaining portion excluding said one end portion is disposed inside the housing (1010). Here, the one end portion of the core body (1020) may also be referred to as a pen tip.

[0138] The core (1020) can be made of a non-conductive material.

[0139] The core (1020) may include a base portion (1021) and an outer portion (1025). The base portion (1021) has a shape that is elongated along the longitudinal direction of the stylus pen (1000). The outer portion (1025) surrounds the side of the base portion (1021). One end of the base portion (1021) is not covered by the outer portion (1025) and is exposed to the outside. The material of the outer portion (1025) is composed of a material that is relatively harder than the material of the base portion (1021) to reinforce and protect the base portion (1021).

[0140] A portion of one end of the core body (1020) can move into the housing (1010) by an external force from the outside. As the external force increases, the volume of the portion of one end of the core body (1020) entering the housing (1010) can increase. When the applied external force decreases, the portion of one end of the core body (1020) comes out of the housing (1010) again. When the external force is removed, the portion of one end of the core body (1020) returns to its initial state.

[0141] The cushioning member (1150) is disposed inside the housing (1010) and is positioned between one end of the ferrite core (1210) and the inner surface of the housing (1010). The cushioning member (1150) may be disposed inside the tapered portion (1010t) of the housing (1010). Here, the tapered portion (101t0) of the housing (1010) is a part adjacent to one end of the core (1020) among the two ends of the housing (1010), and has a shape in which its width or diameter becomes thinner toward the end of one end of the housing (1010).

[0142] The cushioning member (1150) has a conical or polygonal pyramidal shape and has a through hole through which a body portion between one end of the ferrite core (1210) and one end of the core body (1020) penetrates. The inner surface defining the through hole may have a shape corresponding to the outer surface of one end of the ferrite core (1210) and the outer surface of the body portion of the core body (1020). Here, the body portion of the core body (1020) refers to the portion disposed within the through hole of the ferrite core (1210) in a core body (1020) that is elongated in one direction.

[0143] The cushioning member (1150) may be made of an elastic material such as rubber to serve as a cushion between the ferrite core (1210) and the housing (1010). This cushioning member (1150) can block electrical or magnetic influences from the outside.

[0144] The buffer member (1150) has a shape that wraps around one end of the ferrite core (1210).

[0145] A virtual tangent line that is in common contact with the tapered portion (1010t) of the housing (1010) and a portion (or pen tip) of the core (1020) disposed outside the housing (1010) may form a predetermined angle. Here, the predetermined angle may be within 30°, but is not limited thereto. According to an embodiment of the present invention, when the predetermined angle is within 30°, there is an advantage that a stylus pen according to another embodiment of the present invention can be drawn while tilted at 60° with respect to the contact surface.

[0146] The inductor section (1200) can be configured with a capacitor section (not shown) and an LC resonant section. The resonant frequency can be set by the inductance (L) value of the inductor section (1200) and the capacitance (C) value of the capacitor section (not shown). The resonant frequency can be varied according to a change in the inductance (L) value of the inductor section (1200) and / or the capacitance (C) value of the capacitor section (not shown).

[0147] The inductor part (1200) includes a ferrite core (1210) and a coil part (1230) wound on the outer surface of the ferrite core (1210).

[0148] The ferrite core (1210) may have a cylindrical, elliptical, or polygonal shape overall, and a through-hole (1210h) that penetrates the interior along the length direction of the ferrite core (1210) may be formed.

[0149] The ferrite core (1210) has a through-hole (1210h) through which the body portion of the core (1020) passes. Through the through-hole (1210h), the body portion of the core (1020) can move in a straight reciprocating motion along the longitudinal direction.

[0150] One end of the ferrite core (1210) may have a tapered shape in which the diameter or width decreases toward the end. Here, the outer surface of the one end having the tapered shape may include at least one curved surface (not shown) that is curved inward.

[0151] The coil portion (1230) may be wound on a ferrite core (1230) in at least one layer. The coil portion (1230) is electrically connected to the substrate (2100). The coil portion (1230) may include a first connecting portion (1231) and a second connecting portion (1232) for connecting to the substrate (2100). The first connecting portion (1231) is placed on a fixed bracket (1600), and its end is electrically connected to a first terminal portion (2131) of the substrate (2100). The second connecting portion (1232) is placed on a fixed bracket (1600), and its end is electrically connected to a second terminal portion (2132) of the substrate (2100). Here, the fixed bracket (1600) may have a groove in which the first connecting portion (1231) and the second connecting portion (1232) are each placed. The above groove can be formed along the longitudinal direction of the stylus pen (1000) on the outer surface of the fixed bracket (1600). The groove can guide the first connecting part (1231) and the second connecting part (1232) of the coil part (1230), and has the advantage of protecting the first connecting part (1231) and the second connecting part (1232) from external impact.

[0152] FIG. 17 is a perspective view of a stylus pen (1000) according to another embodiment of the present invention shown in FIG. 3, viewed from the direction of the core (1020); FIG. 18 (a) is part of a cross-sectional view taken along A-A' of the stylus pen (1000) shown in FIG. 17; FIG. 18 (b) is part of a cross-sectional view taken along B-B' of the stylus pen (1000) shown in FIG. 17; and FIG. 19 is a drawing showing side views (A, B) and cross-sectional views of a ferrite core (1210) shown in FIG. 17 and FIG. 18.

[0153] Referring to FIGS. 5, 17 to 19, the housing (1010) of the stylus pen (1000) has a rectangular shape with rounded corners, and the portion of the core (1020) exposed in the housing (1010) has a shape in which its width narrows as it goes outward.

[0154] Depending on the external shape of the housing (1010), the components placed inside also correspond to the shape of the housing (1010). Among the internal components, the ferrite core (1210) of the inductor part (1200) also has an optimized structure corresponding to the external shape of the housing (1010).

[0155] As shown in FIG. 18 (a) and (b), the ferrite core (1210) has different cross-sections cut in the first vertical direction (direction AA' in FIG. 17) and the second vertical direction (direction BB' in FIG. 17) perpendicular to the axial direction (x) of the ferrite core (1210). Specifically, the width (w1) of the ferrite core (120) in the first vertical direction is different from the width (w2) in the second direction. More specifically, the width (w1) in the first vertical direction is smaller than the width (w2) in the second direction.

[0156] The ferrite core (1210) has a flat cylindrical shape. A flat portion (1210d) may be disposed on at least one part of the outer surface of the ferrite core (1210). A flat portion corresponding to the flat portion (1210d) may also be disposed on another part of the outer surface of the ferrite core (1210). By means of the flat portion (1210d), the ferrite core (1210) can be stably disposed inside the housing (1010). The flat portion (1210d) is formed to extend from one end to the other end of the ferrite core (1210) along the axial direction (x) of the ferrite core (1210).

[0157] One end of the ferrite core (1210) may include at least two curved sections (1210c). The curved section (1210c) may be a curved surface extending from one side of one end of the ferrite core (1210) to a portion adjacent to the through hole (1210h) of the ferrite core (1210). These curved sections (1210c) may be positioned on opposite sides of one end of the ferrite core (1210) with respect to the through hole (1210h).

[0158] As shown in ①, ②, and ③ of FIG. 19, the curved portion (1210c) changes from an aspherical shape to a spherical shape as it moves along the axial direction (x) of the ferrite core (1210). FIG. 19 ③ shows that the curved portion (1210c) has an aspherical shape, and FIG. 19 ① shows that the curved portion (1210c) has a spherical shape. FIG. 19 ② shows that the curved portion (1210c) has an intermediate shape between an aspherical shape and a spherical shape.

[0159] At one end of the ferrite core (1210), the flat portion (1210d) has a shape in which its width gradually narrows as it moves along the axial direction (x) of the ferrite core (1210). Here, the width of the flat portion (1210d) can be reduced non-linearly.

[0160] By using the ferrite core (1210) described above, the inductor part (1200) including the ferrite core (1210) can be positioned closer to the tip of the core (1020) inside the stylus pen (1000). Thus, the inductor part (1200) can be positioned relatively closer to the receiver side (not shown), which has the advantage of increasing the magnitude of the pen signal received at the receiver side.

[0163] Fixed bracket (1600)

[0164] FIG. 6 is a perspective view of only the fixed bracket (1600) shown in FIG. 5, FIG. 7 is a perspective view of the fixed bracket (1600) shown in FIG. 6 viewed from a different direction, and FIG. 8 is a part of the perspective view of FIG. 5 viewed from a different direction.

[0165] Referring to FIGS. 5 to 8, a fixed bracket (1600) is fixedly positioned inside a housing (1010). The fixed bracket (1600) may be positioned between an inductor part (1200) and a substrate bracket (1900) inside the housing (1010). One end of the fixed bracket (1600) may be coupled to the inductor part (1200), and the other end of the fixed bracket (1600) may be coupled to the substrate bracket (1900).

[0166] One end of the fixed bracket (1600) may include an insertion groove (1620) into which the other end of the ferrite core (1210) of the inductor part (1200) is inserted. The insertion groove (1620) may be defined by the first partition (1611) and the inner wall (1622) of the fixed bracket (1600).

[0167] The first partition (1611) can be in contact with the other end of the ferrite core (1210), and the first partition (1611) has a through hole (1610) through which the core (1020) passes.

[0168] The inner wall (1622) may include a plurality of protrusions (1621) protruding into the insertion groove (1620). The plurality of protrusions (1621) may contact the outer surface of the other end of the ferrite core (1210) and serve to hold the position of the ferrite core (1210).

[0169] The other end of the fixed bracket (1600) may include a locking hole (1660, 1665) into which a locking part (1960, 1965) of the substrate bracket (1900) is inserted. There may be at least one locking hole (1660, 1665), and as shown in the drawing, one may be placed on the upper side and one on the lower side of the fixed bracket (1600). By engaging the locking part (1960) of the substrate bracket (1900) with the locking groove (1660), the fixed bracket (1600) can be coupled to the substrate bracket (1900).

[0170] The other end of the fixed bracket (1600) may include a guide projection (1667). The guide projection (1667) may be formed to extend along the longitudinal direction of the fixed bracket (1600). The guide projection (1667) may be coupled with the guide portion (1967) of the substrate bracket (1900). By coupling the guide projection (1667) with the guide portion (1967) of the substrate bracket (1900), the fixed bracket (1660) can be positioned along the longitudinal direction of the stylus pen (1000).

[0171] The other end of the fixed bracket (1600) may include a second partition (1680). The second partition (1680) fixes the position of the elastic member (1800) together with the substrate bracket (1900). That is, the elastic member (1800) can be fixedly mounted between the second partition (1680) and the substrate bracket (1900).

[0172] A fixed bracket (1600) is positioned to surround a movable bracket (1300), an elastic body (1700), and an elastic member (1800). The fixed bracket (1600) may have an internal storage space (1640) in which the movable bracket (1300), the elastic body (1700), and the elastic member (1800) are positioned. The movable bracket (1300) may move in a linear reciprocating motion within the storage space (1640) of the fixed bracket (1600).

[0173] The fixed bracket (1600) may include two or more electrode patterns (1690). The electrode patterns (1690) may be placed on each of the outer surfaces of both sides of the fixed bracket (1600). The electrode patterns (1690) may be plated on the outer surface of the fixed bracket (1600) made of a non-conductive material. For example, the electrode patterns (1690) may be formed on the outer surface of the non-conductive fixed bracket (1600) using LDS (Laser Direct Structuring) and LMA (Laser Manufacturing Antenna).

[0174] The electrode pattern (1690) may be placed around the guide groove (1630) of the fixed bracket (1600) and may have an uneven shape or an 'L' shape, but is not limited thereto, and may be implemented with a shape having a larger number of bent parts or a smaller number of bent parts. One end of the electrode pattern (1690) may be in contact with the electrode pattern (1390) of the movable bracket (1300) or placed at a predetermined distance apart, and the other end of the electrode pattern (1690) may be electrically connected to the terminal portion (2191, 2192) of the substrate (2100).

[0175] Depending on the movement of the movable bracket (1300) synchronized with the movement of the body (1020), the electrode pattern (1690) may come into contact with the electrode pattern (1390) of the movable bracket (1300), or may be positioned at a predetermined distance from the electrode pattern (1390) of the movable bracket (1300). This will be explained later with reference to a separate drawing.

[0176] Moving bracket (1300)

[0177] FIG. 9 is a perspective view with the inductor part (1200) and the fixing bracket (1600) shown in FIG. 5 removed, FIG. 10 is a perspective view of FIG. 9 viewed from a different direction, and FIG. 11a is a cross-sectional view of FIG. 9.

[0178] Referring to FIGS. 4 to 11a, the movable bracket (1300) moves together with the core body (1020) in synchronization. When one end of the core body (1020) receives an external force from the outside, the core body (1020) moves into the housing (1010), and the movable bracket (1300) moves together with the core body (1020).

[0179] The movable bracket (1300) is configured to accommodate the other end of the core body (1020), the magnetic body (1400), and the holder member (1500). The movable bracket (1300) may have a storage portion that accommodates the other end of the core body (1020), the magnetic body (1400), and the holder member (1500).

[0180] The magnetic body (1400) and the holder member (1500) are arranged to surround the other end of the core body (1020) within the storage portion. To this end, the magnetic body (1400) may have a cylindrical shape and a through-hole through which the other end of the core body (1020) passes, and the holder member (1500) may have a cylindrical shape and a through-hole through which the other end of the core body (1020) passes.

[0181] The magnetic body (1400) contains a material having magnetic properties and moves together with the core body (1020) in synchronization with the movement of the core body (1020). Due to the movement of the magnetic body (1400), the distance to the inductor part (1200) fixedly positioned inside the housing (1010) changes. Due to the change in distance, the inductance of the inductor part (1200) changes.

[0182] The movable bracket (1300) may include a first projection (1330a) and a second projection (1330b). The first projection (1330a) and the second projection (1330b) may protrude outward from the outer surface of the movable bracket (1300) or in a direction perpendicular to the longitudinal direction of the stylus pen (1000). The first projection (1330a) and the second projection (1330b) may be placed in the guide hole (1630) of the fixed bracket (1600) shown in FIG. 5. When the movable bracket (1300) moves in synchronization with the movement of the core body (1020), the first projection (1330a) and the second projection (1330b) may move along the guide hole (1630) of the fixed bracket (1600).

[0183] The movable bracket (1300) may include a third projection (1350). The third projection (1350) may protrude outward from the outer surface of the movable bracket (1300) or in a direction perpendicular to the longitudinal direction of the stylus pen (1000). The third projection (1350) may be placed in a guide hole (1650) of the fixed bracket (1600) shown in FIG. 5. When the movable bracket (1300) moves in synchronization with the movement of the core body (1020), the third projection (1350) may move along the guide hole (1650) of the fixed bracket (1600).

[0184] The movable bracket (1300) may include an extension (1370). The extension (1370) may extend along the longitudinal direction of the stylus pen (1000) from the outer surface of the movable bracket (1300). Alternatively, the extension (1370) may extend along the longitudinal direction of the core (1020) from the outer surface of the movable bracket (1300). The extension (1370) may have a structure and shape that can be placed inside the elastic body (1700). An extension (1870) of the elastic member (1800) may be placed on the end portion of the extension (1370).

[0185] The movable bracket (1300) may include an electrode pattern (1390). The electrode pattern (1390) may be disposed on the outer surface where the extension (1370) is formed among the outer surfaces of the movable bracket (1300), and on the first and second protrusions (1330a, 1330b).

[0186] The electrode pattern (1390) can be electrically connected by contacting the elastic body (1700) surrounding the extension (1370) of the movable bracket (1300). The electrode pattern (1390) can be electrically connected by contacting the electrode pattern (1690) of the fixed bracket (1600) shown in FIG. 5, and can be electrically separated by the movement of the core body (1020) by disconnecting the contact with the electrode pattern (1690) of the fixed bracket (1600).

[0187] The electrode pattern (1390) may be plated on the outer surface of a movable bracket (1300) made of a non-conductive material. For example, the electrode pattern (1390) may be formed on the outer surface of a movable bracket (1300) made of a non-conductive material using LDS (Laser Direct Structuring) and LMA (Laser Manufacturing Antenna).

[0188] The electrode pattern (1390) may include a base electrode pattern (1391) and first and second extension patterns (1393a, 1393b).

[0189] The base electrode pattern (1391) is positioned on the outer surface of the movable bracket (1300) and may be positioned to surround the extension (1370) of the movable bracket (1300). The base electrode pattern (1391) is in contact with one end of the elastic body (1700).

[0190] The first and second extension patterns (1393a, 1393b) extend from both sides of the base electrode pattern (1391), respectively, and the first extension pattern (1393a) may be placed on the first projection (1330a), and the second extension pattern (1393b) may be placed on the second projection (1330b). The first and second extension patterns (1393a, 1393b) may come into contact with the electrode pattern (1690) of the fixed bracket (1600) shown in FIG. 5, or the contact may be released by the movement of the core body (1020).

[0191] According to another embodiment of the present invention, the movable bracket (1300) may further include an additional projection (not shown) in addition to the first projection (1330a) and the second projection (1330b), and the base electrode pattern (1391) may further include one or more extension patterns (not shown) in addition to the first and second extension patterns (1393a, 1393b). For example, if two additional extension patterns are included in addition to the first and second extension patterns (1393a, 1393b), the two additional extension patterns may each extend to the upper and lower parts of the base electrode pattern (1391) and be respectively placed on the additional projection (not shown). In this way, when the base electrode pattern (1391) includes a plurality of extension patterns, even if some of the plurality of extension patterns do not come into contact with the electrode pattern (1690) of the fixed bracket (1600), at least some of the remaining extension patterns can still remain in contact with the electrode pattern (1690), so there is an advantage that the hover state and the contact state can be clearly distinguished without error.

[0192] In addition, according to an embodiment of the present invention, the electrode pattern (1390) of the movable bracket (1300), which is electrically connected by contact with the electrode pattern (1690) of the fixed bracket (1600), may be implemented in the shape of a plated electrode pattern rather than a wire shape. When the electrode is electrically connected by being implemented in the shape of a wire, the electrical contact state may be unintentionally released due to defects such as the wire breaking. In contrast, when the electrode pattern (1390) of the movable bracket (1300) is in contact with the electrode pattern (1690) disposed on the outer surface of the fixed bracket (1600), there is an advantage that such unintentional electrical release can be prevented.

[0193]

[0194] Holder member (1500)

[0195] Figures 11b (a) and (b) are drawings illustrating the holder member (1500) shown in Figures 9 and 11a. The holder member (1500) comprises an elastic material and can be positioned by being sandwiched between the other end of the core body (1020) and the movable bracket (1300). The other end of the core body (1020) can be protected by the holder member (1500), and since the holder member (1500) is sandwiched between the other end of the core body (1020) and the movable bracket (1300), the movable bracket (1300) can be synchronized with the movement of the core body (1020).

[0196] In order for the movable bracket (1300) to move together with the core body (1020) in synchronization, it may be preferable for a holder member (1500) arranged to surround the other end of the core body (1020) to fix the core body (1020) to the movable bracket (1300).

[0197] As illustrated in FIG. 11b (a) and (b), the holder member (1500) may include an inner space in which the core body (1020) is located. A holder member (1500) according to one embodiment of the present invention is positioned between a movable bracket (1300) and the core body (1020) so that even if a force (e.g., tension) is applied to the core body (1020) in the direction of one end of the stylus pen, the core body (1020) is not dislodged from inside the housing (1010) if the applied force is less than a threshold value. For example, the core body (1020) may be dislodged by the holder member (1500) only when pulled by a force of about 100gf or more, but specific numerical values ​​are merely examples and are not limited thereto. The function of this holder member (1500) is designed so that no excessive force is required when attempting to detach the core (1020) from the stylus pen, while providing stability to prevent the core (1020) from unnecessarily detaching during use.

[0198] Meanwhile, a holder member (1500) according to one embodiment of the present invention may include an elastic material. By utilizing the elasticity of the holder member (1500), the overlap dimension between the outer diameter of the core (1020) and the inner space of the holder member (1500) can be adjusted, thereby providing a stable fixing force to the core (1020) of the holder member (1500). For example, even if the width of the inner space of the holder member (1500) is smaller than the outer diameter of the core (1020), the core (1020) can be fitted into the inner space of the holder member (1500) by means of the elasticity of the holder member (1500), and the core (1020) can be stably fixed to the inner space of the holder member (1500).

[0199] In the case where the holder member (1500) according to one embodiment of the present invention includes an elastic material, a relatively large overlap dimension can be allowed due to the elasticity, thereby providing a high degree of design freedom. In addition, even if the dimension of at least one of the internal components of the stylus pen according to one embodiment of the present invention changes, the fixing force of the core body (1020) can be maintained at a constant or, in some cases, flexibly adjusted due to the elasticity of the holder member (1500), thus providing the advantage of increased freedom in the design and mass production process.

[0200] The holder member (1500) may include a protrusion (1510) that protrudes outward from the outer surface, as shown in (b) of FIG. 11a and FIG. 11b. The protrusion (1510) may be fitted into an insertion groove (1310) formed in the movable bracket (1300). By means of the protrusion (1510) of the holder member (1500) and the insertion groove (1310) of the movable bracket (1300), the holder member (1500) can be stably fixed to the movable bracket (1300), and accordingly, the other end of the core body (1020) can be fixed to the movable bracket (1300).

[0201] In a stylus pen according to one embodiment of the present invention, since the core body (1020) is fixed to the movable bracket (1300) by means of a holder member (1500), when a force is applied to one end of the core body and the core body (1020) moves, the movable bracket (1300) also moves together, and the electrode pattern (1390) included in the movable bracket (1300) also moves together. Accordingly, since the movement of the core body (1020) and the movement of the electrode pattern (1390) are synchronized, there is an effect of reducing the error in the electrical contact and release operation between the electrode pattern (1390) of the movable bracket (1300) and the electrode pattern (1690) of the fixed bracket (1600) caused by the movement of the core body (1020).

[0202]

[0203] Elastic body (1700)

[0204] The elastic body (1700) is composed of a conductive material and may have a spring shape. The elastic body (1700) may be placed between the movable bracket (1300) and the elastic member (1800). Here, the elastic body (1700) may be inserted between the movable bracket (1300) and the elastic member (1800) in a partially compressed state rather than a fully compressed state. If the external force applied to the movable bracket (1300), which is synchronized with the movement of the core body (1020), is smaller than the elastic force pushing outward from the partially compressed elastic body (1700), the elastic body (1700) is not compressed, and if the external force becomes larger than the elastic force, the elastic body (1700) begins to be compressed. That is, the elastic force pushing outward from the partially compressed elastic body (1700) may be a predetermined threshold value that is compared with the external force applied to the core body (1020).

[0205] The extension (1370) of the movable bracket (1300) and the extension (1870) of the elastic member (1800) can be arranged together inside the elastic body (1700). This allows the internal space of the elastic body (1700) to be utilized, thereby providing the advantage of reducing the volume inside the stylus pen (1000).

[0206] One end of the elastic body (1700) is electrically connected to the electrode pattern (1390) of the movable bracket (1300), and the other end is electrically connected to the terminal portion (2110) of the substrate (2100). The elastic body (1700) may include a connecting line (1710) connecting the elastic body (1700) and the terminal portion (2110) of the substrate (2100). One end of the connecting line (1710) may be connected to the elastic body (1700), and the other end may be connected to the terminal portion (2110) of the substrate (2100). To protect and guide the connecting line (1710), the elastic member (1800) and the substrate bracket (1900) may have a guide groove in which the connecting line (1710) is placed.

[0207]

[0208] Elastic member (1800)

[0209] FIG. 12 is a perspective view of only the elastic member (1800) shown in FIG. 9, and FIG. 13 is a perspective view of the substrate bracket (1900) and the substrate (2100) shown in FIG. 9.

[0210] Referring to FIGS. 6 through 13, the elastic member (1800) may include an extension (1870). The extension (1870) may extend from the outer surface of the elastic member (1800) toward the movable bracket (1300). The extension (1870) may be disposed inside the elastic body (1700).

[0211] The elastic member (1800) may include a guide groove (1810). The guide groove (1810) may be formed along the longitudinal direction of the stylus pen (1000) on the outer surface of the elastic member (1800). An extension line (1710) of the elastic body (1700) may be disposed in the guide groove (1810).

[0212] The elastic member (1800) may include a mounting groove (1850). The mounting groove (1850) is formed on the outer surface of the elastic member (1800). The mounting groove (1850) may be positioned on the side facing the extension portion (1870). A mounting portion (1910) of a substrate bracket (1900) may be inserted into the mounting groove (1850). A catch groove (1851) having a shape corresponding to a protrusion (1915) of the mounting portion (1910) of the substrate bracket (1900) may be formed inside the mounting groove (1850). Through this, the elastic member (1800) can be stably fixedly mounted to the substrate bracket (1900).

[0213] The elastic member (1800) is made of a non-conductive material and has a certain elasticity. For example, the elastic member (1800) may be rubber. The elastic member (1800) may be placed between the movable bracket (1300) and the substrate bracket (1900).

[0214]

[0215] Substrate bracket (1900) and substrate (2100)

[0216] Referring to FIGS. 5 to 13, the substrate (2100) is placed on the substrate bracket (1900).

[0217] The substrate bracket (1900) supports the substrate (2100) inside the housing (1010) and is combined with the elastic member (1800) to support the elastic member (1800).

[0218] The substrate bracket (1900) may include a side (1940) that guides and supports the side of the substrate (2100).

[0219] The substrate bracket (1900) may include a mounting portion (1910) for coupling with an elastic member (1800). The mounting portion (1910) protrudes from the substrate bracket (1900) toward the movable bracket (1300). The mounting portion (1910) may include protrusions (1915) protruding from the outer surface. The protrusions (1915) may protrude in a direction perpendicular to the direction of protrusion of the mounting portion (1910).

[0220] The substrate bracket (1900) may include a guide groove (1920). The guide groove (1920) can guide and protect the connecting line (1710) of the elastic body (1700).

[0221] The substrate (2100) may include a plurality of terminal portions (2110, 2131, 2132, 2191, 2192). Among the plurality of terminal portions (2110, 2131, 2132), the terminal portion (2110) is electrically connected to an elastic body (1700), and the first and second terminal portions (2131, 2132) are electrically connected to the coil portion (1230) of the inductor portion (1200). The third and fourth terminal portions (2191, 2192) are electrically connected to electrode patterns (1690) respectively disposed on both sides of the outer surface of the fixed bracket (1600).

[0222] The substrate (2100) includes a capacitor section (not shown). One or more capacitors constituting the capacitor section (not shown) may be disposed on the substrate (2100).

[0223] The substrate (2100) may include a circuit pattern that electrically connects one or more capacitors of a capacitor section (not shown) and a plurality of terminal sections (2110, 2131, 2132).

[0224]

[0225] Movement of internal composition according to the movement of the body

[0226] FIG. 14 is a drawing for explaining the movement of the movable bracket (1300) according to the movement of the core body (1020) shown in FIG. 5 to 13, and the electrical contact and release of contact between the fixed bracket (1600) and the movable bracket (1300).

[0227] FIG. 14 (a) shows the state when no external force is applied to the core body (1020), and FIG. 14 (b) shows the state where a predetermined external force is applied to the core body (1020) and the moving bracket (1300) moves in one direction.

[0228] First, referring to FIG. 14 (a), when no external force is applied to the core body (1020), the electrode pattern (1390) of the movable bracket (1300) comes into contact with the electrode pattern (1690) of the fixed bracket (1600). That is, the electrode pattern (1390) of the movable bracket (1300) and the electrode pattern (1690) of the fixed bracket (1600) are electrically connected to each other.

[0229] The elastic body (1700) can be inserted between the movable bracket (1300) and the elastic member (1800) in a partially compressed state. Due to the partially compressed elastic body (1700), the second projection (1330b) of the movable bracket (1300) is pushed toward the core body (1020), so that the electrode pattern (1390) placed on the outer surface of the second projection (1330b) can be maintained in contact with the electrode pattern (1690) of the fixed bracket (1600).

[0230] If the external force applied to the movable bracket (1300) synchronized with the movement of the core body (1020) is smaller than the elastic force that causes the partially compressed elastic body (1700) to push the movable bracket (1300) outward, the elastic body (1700) is not compressed, and the electrical connection between the electrode pattern (1390) and the electrode pattern (1690) is not severed. In this case, although the electrical connection between the electrode pattern (1390) and the electrode pattern (1690) is not severed, a certain displacement may occur in the movable bracket (1300) due to the deformation of the shape of the elastic member (1800) having a certain elasticity. When displacement of the movable bracket (1300) occurs, displacement also occurs in the magnetic body (1400) housed in the movable bracket (1300), and the inductance (L) value of the inductor part (1200) may change.

[0231] When the external force applied to the moving bracket (1300), which is synchronized with the movement of the core body (1020), is greater than the elastic force that causes the partially compressed elastic body (1700) to push the moving bracket (1300) outward, the elastic body (1700) is compressed, causing the moving bracket (1300) to move in the same direction as the external force, and the electrical connection between the electrode pattern (1390) and the electrode pattern (1690) is broken. As described later, when the electrical connection between the electrode pattern (1390) and the electrode pattern (1690) is broken, the auxiliary capacitor (Cs) is electrically disconnected from the plurality of primary capacitors, causing a change in the capacitance (C) value. In this case, the inductance (L) value of the inductor part (1200) may change as the core body (1020) moves.

[0232] Next, referring to FIG. 14(b), when a predetermined external force is applied to the core body (1020) and the core body (1020) moves in one direction, the movable bracket (1300) moves in conjunction with the core body (1020) in the said one direction. Due to the movement of the movable bracket (1300) in the said one direction, the second protrusion (1330b) also moves in the said one direction. Due to the movement of the second protrusion (1330b), the electrode pattern (1390) of the movable bracket (1300) is released from contact with the electrode pattern (1690) of the fixed bracket (1600). Likewise, the first protrusion (1330a) located on the opposite side of the second protrusion (1330b) is also moved, and the electrode pattern (1390) of the movable bracket (1300) is released from contact with the electrode pattern (1690) of the fixed bracket (1600). And, the elastic body (1700) is compressed by the movement of the moving bracket (1300).

[0233] As illustrated in FIG. 14(b), when a predetermined external force is applied to the core body (1020) and the core body (1020) moves in one direction, the contact between the electrode pattern (1390) of the moving bracket (1300) and the electrode pattern (1690) of the fixed bracket (1600) is released. Due to the release of the contact, the capacitance of the capacitor part (not shown) mounted on the substrate (2100) changes rapidly. The rapid change in capacitance changes the frequency of the pen signal emitted from the stylus pen (1000). The receiving side receiving the pen signal can detect the changed frequency and determine that the stylus pen (1000) has made contact with the screen.

[0234] FIG. 15 is a schematic representation of FIG. 14 (a) and (b), respectively, and FIG. 16 is a simplified stylus pen according to another embodiment of the present invention, and FIG. 14 (a) and (b), respectively, configured as an equivalent circuit diagram.

[0235] Referring to (a) and (b) of FIGS. 15 and 16, a plurality of capacitors (C1, C2, C3, Cs) are disposed on a substrate (2100). The plurality of capacitors (C1, C2, C3, Cs) may form a capacitor section (not shown). Among the plurality of capacitors (C1, C2, C3, Cs), at least one capacitor (C1, C2, C3) is connected in parallel with each other to maintain a constant capacitance value, and the auxiliary capacitor (Cs) is connected in parallel with the primary capacitor or is not connected to the primary capacitor depending on the contact or release of contact between the electrode pattern (1690) of the fixed bracket (1600) shown in FIG. 14 and the electrode pattern (1390) of the movable bracket (1300).

[0236] First, as illustrated in FIG. 15 (a) and FIG. 16 (a), when no external force is applied to the core body (1020), the electrode pattern (1690) of the fixed bracket (1600) and the electrode pattern (1390) of the movable bracket (1300) are in contact with each other, so the auxiliary capacitor (Cs) is connected in parallel with the basic capacitors (C1, C2, C3). Therefore, the capacitance of the capacitor section (not shown) becomes the sum of the capacitance values ​​of the basic capacitors (C1, C2, C3) and the capacitance of the auxiliary capacitor (Cs).

[0237] Next, as illustrated in FIG. 15 (b) and FIG. 16 (b), when a predetermined external force is applied to the core body (1020), the electrode pattern (1390) of the movable bracket (1300) is released from contact with the electrode pattern (1690) of the fixed bracket (1600) by the movement of the movable bracket (1300) synchronized with the movement of the core body (1020). Consequently, the auxiliary capacitor (Cs) is not electrically connected to the basic capacitor (C1, C2, C3), and the capacitance of the capacitor part (not shown) is changed to the capacitance value of the basic capacitor (C1, C2, C3).

[0238] In particular, referring to FIG. 16(b), it can be seen that the electrode pattern (1390) of the movable bracket (1300) contacts the electrode pattern (1690) of the fixed bracket (1600) in two parts. This can be understood from the fact that, as shown in FIG. 9 and FIG. 10, the fixed bracket (1600) has two electrode patterns (1690), and the first and second extension patterns (1393a, 1393b) are placed on the first and second protrusions (1330a, 1330b) of the movable bracket (1300).

[0239] If the external force applied to the core body (1020) does not reach a level that separates both the first and second extension patterns (1393a, 1393b) from the two electrode patterns (1690) of the fixed bracket (1600), that is, if the first extension pattern (1393a) separates from one electrode pattern (1690) of the fixed bracket (1600) but the second extension pattern (1393b) does not separate from the other electrode pattern (1690) of the fixed bracket (1600), then the auxiliary capacitor (Cs) is still maintained in parallel with the primary capacitor (C1, C2, C3).

[0240] On the other hand, the auxiliary capacitor (Cs) is electrically disconnected from the basic capacitor (C1, C2, C3) only when the external force applied to the core body (1020) reaches a level sufficient to completely detach both the first and second extension patterns (1393a, 1393b) from the two electrode patterns (1690) of the fixed bracket (1600). Additionally, as previously described, if the movable bracket (1300) includes additional protrusions (not shown) in addition to the first protrusion (1330a) and the second protrusion (1330b), and the base electrode pattern (1391) includes one or more extension patterns (not shown) in addition to the first and second extension patterns (1393a, 1393b), the auxiliary capacitor (Cs) is electrically disconnected from the basic capacitor (C1, C2, C3) only when all of the multiple extension patterns are completely detached from the electrode pattern (1690).

[0241] Accordingly, when using a stylus pen (1000) according to another embodiment of the present invention, a reference pressure distinguishing between hover and contact can be clearly set, which has the advantage of clearly distinguishing between hover and contact. In particular, even if some of the extension patterns among the plurality of extension patterns including the first and second extension patterns (1393a, 1393b) do not come into contact with some of the two or more electrode patterns (1690) of the fixed bracket (1600) due to manufacturing process problems or user negligence during the manufacture of the stylus pen, the stylus pen (1000) according to another embodiment of the present invention can maintain a state in which the remaining extension patterns and the remaining electrode patterns are still in contact, so there is an advantage that the hover state, contact state, and writing pressure state can be clearly distinguished.

[0242] Stylus movement according to body movement

[0243] Hereinafter, stylus operation according to the movement of the core body to distinguish hover, contact, pressure, and button states according to an embodiment of the present invention will be explained.

[0244] Hereinafter, the operation of a stylus pen (100) or a stylus pen (1000) according to an embodiment of the present invention will be described with reference to FIGS. 20 and 21.

[0245] FIGS. 20 (a) to (c) are drawings for explaining the operation of a stylus pen according to an embodiment of the present invention. Specifically, FIG. 20 (a) is a drawing showing the hover state (H) of the stylus pen, FIG. 20 (b) is a drawing showing the contact state (c) of the stylus pen, and FIG. 20 (c) is a drawing showing the pressure (P) state of the stylus pen.

[0246] In the hover state (H), the touch input device may not receive a signal from the stylus pen, or even if a signal is received, it may be recognized that the stylus pen is not in contact with the touch input device. For example, if no external force is applied to the core body (1020), or if the magnitude of the external force applied to the core body (1020) is smaller than the elastic force that pushes the compressed elastic body (1700) outwardly, it may be recognized as the hover state (H).

[0247] Referring to FIG. 14 (a) and FIG. 20 (a), when no external force is applied to the core body (1020), it can be recognized as a hover state (H). In this case, there is no change in the internal components. No deformation of the elastic member (1800) occurs, and the electrical connection between the electrode pattern (1390) of the movable bracket (1300) and the electrode pattern (1690) of the fixed bracket (1600) is not broken. No change in position occurs between the magnetic body (1400) and the inductor part (1200), so the inductance (L) value is maintained constant. Therefore, the inductance (L) value of the inductor part (1200) and the capacitance (C) value of the capacitor part are each maintained constant, so the resonance frequency of the resonance circuit is maintained constant.

[0248] Referring to FIG. 14 (a) and FIG. 20 (a), even if a predetermined external force is applied to one end of the core body (1020) in the hover state (H), the hover state (H) can be recognized when the magnitude of the predetermined external force applied here is smaller than the magnitude of the elastic force that pushes the compressed elastic body (1700) outwardly, thereby pushing the movable bracket (1300). Since the predetermined external force applied to the core body (1020) is smaller than the magnitude of the elastic force of the elastic body (1700), the elastic body (1700) is not compressed, and since no movement of the movable bracket (1300) occurs, there is no change in the internal components. Since no deformation of the shape of the elastic member (1800) occurs, and the electrical connection between the electrode pattern (1390) of the movable bracket (1300) and the electrode pattern (1690) of the fixed bracket (1600) is not broken, no change in the capacitance of the capacitor part (not shown) occurs. In addition, since no change in position occurs between the magnetic body (1400) and the inductor part (1200), the inductance (L) value is maintained constant. Therefore, the inductance (L) value of the inductor part (1200) and the capacitance (C) value of the capacitor part are each maintained constant, so the resonance frequency of the resonance circuit is maintained constant.

[0249] In the contact state (c), a signal from the stylus pen is received by the touch input device, and the stylus pen can be recognized as being in contact with the touch input device. For example, if the magnitude of the external force applied to the core body (1020) is greater than or equal to the elastic force that pushes the compressed elastic body (1700) outwardly, the contact state (c) can be recognized.

[0250] Referring to FIG. 14(b) and FIG. 20(b), in the contact state (c), the external force applied to the movable bracket (1300), which is synchronized with the movement of the core body (1020), is greater than or equal to the elastic force of the partially compressed elastic body (1700) pushing the movable bracket (1300) outward; thus, the movable bracket (1300) moves in the same direction as the external force, and the contact between the electrode pattern (1390) of the movable bracket (1300) and the electrode pattern (1690) of the fixed bracket (1600) is released. When the contact between the electrode pattern (1390) and the electrode pattern (1690) is released, as shown in FIG. 14 to 16, due to the release of contact, the auxiliary capacitor (C1, C2, C3) that was connected in parallel with the basic capacitors (C1, C2, C3) in the capacitor part (not shown) mounted on the substrate (2100) S Since the electrical connection of ) is broken, the total capacitance value of the capacitor part (not shown) decreases.

[0251] As the movable bracket (1300) moves in the same direction as the external force, the elastic member (1800) is compressed by the external force transmitted to the movable bracket (1300) linked to the core body (1020), causing a deformation of shape. Due to the deformation of the elastic member (1800), a certain displacement occurs in the movable bracket (1300), and a displacement also occurs in the magnetic body (1400) housed in the movable bracket (1300). The inductance (L) value of the inductor part (1200) changes according to the displacement of the magnetic body (1400). Therefore, in this case, the total capacitance value of the capacitor part (not shown) and the inductance (L) value of the inductor part (1200) change together, and the resonance frequency of the resonance circuit can be varied. In the contact state (c), the total capacitance value and the inductance value change together, but the change in the capacitance value may be greater than the change in the inductance value. In this case, the change in the capacitance value may have a dominant effect on the change in the LC value.

[0252] In the pressure state (P), a signal from the stylus pen is received by the touch input device, and it can be recognized that the stylus pen is in contact with the touch input device in a compressed state. For example, if the magnitude of the external force applied to the core body (1020) is greater than the elastic force that pushes the compressed elastic body (1700) outwardly, it can be recognized as the pressure state (P).

[0253] Referring to (c) of FIG. 20, in the pressure state (P), an external force greater than that in the contact state (c) is applied to one end of the core body (1020). In the pressure state (P), even after the contact between the electrode pattern (1390) and the electrode pattern (1690) is released, the elastic member (1800) is further compressed by the external force applied to one end of the core body (1020), and the movable bracket (1300) can move inwardly in the housing (1010) due to the deformation of the compressed elastic member (1800). When the movable bracket (1300) moves in the pressure state (P), displacement of the magnetic body (1400) housed in the movable bracket (1300) occurs, and because the magnetic body (1400) and the inductor part (1200) move away from each other, the inductance (L) value gradually decreases. In this case, since the contact between the electrode pattern (1390) and the electrode pattern (1690) is released, the capacitance value is constant, but the inductance value changes, so the resonant frequency of the resonant circuit can be varied. Therefore, in this case, the change in the inductance value can have a dominant effect on the change in the LC value.

[0254]

[0255] FIG. 21 (a) illustrates, as an example, the change in LC values ​​of the resonant circuit section according to the operation of FIG. 20 (a) to (c), where the Th section represents the hover state (H) of FIG. 20 (a), the Tc section represents the contact state (c) of FIG. 20 (b), and the Tp section represents the pressure state (P) of FIG. 20 (c). FIG. 21 (b) is a graph showing the frequency characteristics in each operation state of FIG. 20 (a) to (c).

[0256] Referring to FIG. 21 (a), the LC value of the resonant circuit part, which is composed of a capacitor part (not shown) and an inductor part (1200), maintains a constant value during the Th period. During the Th period, the core body (1020) of the stylus pen may not come into contact with the touch surface, so no external force may be applied to the core body (1020). Alternatively, even if the core body (1020) of the stylus pen comes into contact with the touch surface, the magnitude of the external force applied to the core body (1020) may be smaller than the elastic force of the compressed elastic body (1700) pushing the movable bracket (1300) outward.

[0257] In the Th section, since the predetermined external force applied to the core body (1020) is smaller than the magnitude of the elastic force of the elastic body (1700), the elastic body (1700) is not compressed, and the electrical connection between the electrode pattern (1390) of the movable bracket (1300) and the electrode pattern (1690) of the fixed bracket (1600) is not broken, so there is no change in the total capacitance value of the capacitor section (not shown). In addition, since no deformation of the shape of the elastic member (1800) occurs, there is no movement of the movable bracket (1300), and since there is no change in the distance between the magnetic body (1400) housed in the movable bracket (1300) and the inductor section (1200), there is no change in the inductance value of the inductor section (1200). Therefore, the resonance frequency value of the resonance circuit is maintained at a constant level.

[0258] Referring to FIG. 21 (a), the LC value of the resonant circuit may decrease rapidly during the Tc interval (or time point). During the Tc interval (or time point), after the core body (1020) contacts the touch surface, the magnitude of the external force applied to the core body (1020) may be greater than or equal to the elastic force of the compressed elastic body (1700) pushing the moving bracket (1300) outward.

[0259] In the Tc interval (or time point), after the core body (1020) contacts the touch surface, if an external force greater than or equal to the magnitude of the elastic force that pushes the compressed elastic body (1700) outwardly, the contact between the electrode pattern (1390) of the movable bracket (1300) and the electrode pattern (1690) of the fixed bracket (1600) is released. Due to the release of contact, the auxiliary capacitor (C1, C2, C3) that was connected in parallel with the basic capacitors (C1, C2, C3) in the capacitor section (not shown) mounted on the substrate (2100) S As the electrical connection of the capacitor (not shown) is severed, the total capacitance value of the capacitor (not shown) decreases. Additionally, the elastic member (1800) is compressed by an external force transmitted to the movable bracket (1300) linked to the core (1020), causing a deformation of its shape. Due to the deformation of the elastic member (1800), the movable bracket (1300) moves, and a change in the distance between the magnetic body (1400) housed in the movable bracket (1300) and the inductor (1200) occurs, causing the inductance value of the inductor (1200) to decrease. As the capacitance value and the inductance value change, the resonance frequency value of the resonance circuit decreases.

[0260] According to one embodiment of the present invention, the inductance value also changes during the Tc interval (or time point), but the capacitance value changes rapidly, so the change in the capacitance value due to the applied pressure acts predominantly on the change in the LC value.

[0261] Referring to FIG. 21 (a), the LC value of the resonant circuit part, which is composed of a capacitor part (not shown) and an inductor part (1200), gradually decreases as more pressure is applied during the Tp period. During the Tp period, after the core body (1020) contacts the touch surface, the magnitude of the external force applied to the core body (1020) is greater than the elastic force of the compressed elastic body (1700) pushing the movable bracket (1300) outward.

[0262] In the Tp section, even after the contact between the electrode pattern (1390) of the movable bracket (1300) and the electrode pattern (1690) of the fixed bracket (1600) is released, the elastic member (1800) is further compressed by the external force applied to one end of the core body (1020), and the movable bracket (1300) can move further inward toward the housing (1010) due to the deformation of the compressed elastic member (1800). In this case, as the pressure applied to the core body (1020) increases, the magnetic body (1400) housed in the movable bracket (1300) moves further away from the inductor part (1200), so the inductance value is further reduced, and the LC value of the resonant circuit part is further reduced. That is, in this section (Tp), as the pressure applied to the core body (1020) increases, the LC value of the resonant circuit part can gradually decrease. However, since the total capacitance value remains constant even if the inductance value decreases in this range (Tp), the main factor determining the LC value is inductance. Therefore, in this range (Tp), the change in inductance due to the applied pressure acts dominantly on the change in the LC value.

[0263] Referring to FIG. 21 (a), the LC value of the resonant circuit section is shown as hover state (H) > contact state (c) > pressure state (P). If the inductance value of the inductor section (1200) and the capacitance value of the capacitor section (not shown) are changed, the resonant frequency and Q value of the resonant circuit section may change. The resonant frequency of the resonant circuit section increases as the inductance of the resonant circuit section decreases, and the Q value decreases as the inductance decreases. Therefore, as shown in FIG. 21 (b), the frequency characteristics of the resonant signal (Vpen) output from the resonant circuit section can be such that the resonant frequency increases (hover state < contact state < pressure state) and the Q value decreases (hover state > contact state > pressure state) as the distance traveled by the core body (1020) increases, that is, as the pressure increases.

[0264] When the resonant frequency of the resonant circuit changes, the phase of the electromagnetic signal output from the stylus pen (1000) changes. The stylus pen sensing device interacting with the stylus pen (1000) calculates the change in the LC value of the resonant circuit based on this change in phase, and based on this, the contact status and pressure of the stylus pen (1000) with the stylus pen sensing device can be detected.

[0265] As described above, a stylus pen (1000) according to one embodiment of the present invention can detect writing pressure in a stylus pen sensing device (e.g., a touch input device or a touch panel) by changing at least one of the inductance value and the capacitance value of the resonant circuit. In addition, it has the advantage of being able to sense precise writing pressure. Furthermore, even if a predetermined writing pressure is applied in a contact state (c), if the predetermined writing pressure is smaller than the magnitude of the elastic force of the elastic body (1700), an auxiliary capacitor (C S Since the electrical connection of ) is not interrupted, there is an advantage in that the contact state (c) and the pressure state (P) can be distinguished more precisely.

[0266] Distinction between Hover, Contact, and Pressure at Low Reference Pressure

[0267] Referring to FIG. 14, the elastic body (1700) may be composed of a spring. The elastic body (1700) begins to be compressed from a low pressure (e.g., around 10gf or around 5gf, etc.) and may be arranged so that it is compressed quickly even when the pressure increases only slightly, as the compression strength is weak.

[0268] FIGS. 22 (a) and (b) are drawings for explaining the elastic body (1700) and elastic member (1800) shown in FIGS. 9. FIGS. 22 (a) is a drawing showing the case where no external force is applied to the elastic body (1700) or where the magnitude of the external force applied to the elastic body (1700) is smaller than the elastic force that pushes the compressed elastic body (1700) outwardly, and FIGS. 22 (b) is a drawing showing the contact surface between the movable bracket (1300) and the elastic member (1800) shown in FIGS. 9 placed between the elastic body (1700). According to FIGS. 11a and FIGS. 22 (b), the extension (1370) of the movable bracket (1300) and the extension (1870) of the elastic member (1800) can be placed together inside the elastic body (1700).

[0269] The elastic body (1700) may be positioned in a partially compressed (or incompletely compressed) state by being sandwiched between the movable bracket (1300) and the elastic member (1800), as illustrated in FIG. 22 (b). The elastic body (1700) may be configured to respond to a weight relatively greater than that of the elastic member (1800). The elastic body (1700) will not be compressed unless a force (or repulsive force) greater than that applied by the movable bracket (1300) and the elastic member (1800) is applied. Here, the force (or repulsive force) may be, for example, around 10 (gf), but is not limited thereto and may be a smaller value, such as 5 (gf). The force (or repulsive force) can be calculated and adjusted using the following [Equation 1].

[0270] [Mathematical Formula 1]

[0271]

[0272] In the above [Equation 1], G represents the shear modulus of the spring, Na represents the effective number of turns of the spring, D represents the diameter of the spring, d represents the diameter of the wire, and x represents the length of the spring compressed (in the -direction).

[0273] By adjusting F, which is the magnitude of the force (or repulsive force) calculated by [Equation 1] above, to a smaller value, the minimum force required to reach the contact state (c) from the hover state (H) can be adjusted to a weaker value, and accordingly, the hover state and contact state of the stylus pen can be clearly distinguished even at low reference pressure.

[0274] By significantly adjusting F, which is the magnitude of the force (or repulsive force) calculated by [Equation 1] above, the minimum force required to reach the contact state (c) from the hover state (H) can be strongly adjusted, and accordingly, it is also possible to adjust so that the hover state and contact state of the stylus pen can be distinguished at a high reference pressure.

[0275] If the magnitude of the force (or repulsive force) calculated by [Equation 1] above is adjusted to a very low value, the minimum force required to reach the contact state (c) from the hover state (H) can be adjusted to a very weak value, and it is also possible to adjust the hover state and contact state of the stylus pen to be distinguishable at a very low reference pressure.

[0276] Meanwhile, the elastic body (1700) may be positioned between the movable bracket (1300) and the elastic member (1800) in an uncompressed state. Accordingly, a stylus pen according to another embodiment of the present invention is not limited to a case where a part of the elastic body (1700) is positioned in a compressed state between the movable bracket (1300) and the elastic member (1800).

[0279] Moisture inflow pathway

[0280] First moisture inflow path and second moisture inflow path

[0281] FIG. 23a is a drawing showing a first moisture inflow path and a second moisture inflow path through which moisture is introduced through the core opening of the housing with the stylus pen illustrated in FIG. 2a. FIG. 23b is a drawing showing a first moisture inflow path and a second moisture inflow path through which moisture is introduced through the core opening of the housing with the stylus pen illustrated in FIG. 3. FIG. 24 is a drawing for explaining in detail the second moisture inflow path of the stylus pen illustrated in FIG. 3.

[0282] As shown in FIG. 23a, moisture can be introduced into the interior of the stylus pen (100) shown in FIG. 2a through the core opening (not shown) of the housing (101). Here, the core opening (not shown) may refer to the space between the housing (101) and the core (102).

[0283] Specifically, as shown in FIG. 23a (a), moisture may be introduced into the interior of the stylus pen (100) through a first moisture inflow path (P1), which is a path through which moisture is introduced into the interior of the stylus pen (100) by passing through the core opening (not shown) of the housing (101) and the space between the housing (101) and the inductor part (120). Alternatively, specifically, as shown in FIG. 23a (b), moisture may be introduced into the interior of the stylus pen (100) through a second moisture inflow path (P2), which is a path through which moisture is introduced into the interior of the stylus pen (100) by passing through the core opening (not shown) of the housing (101) and the through hole of the ferrite core (121).

[0284] As illustrated in FIG. 23b, moisture can be introduced into the interior of the stylus pen (1000) illustrated in FIG. 3 through the core opening (not shown) of the housing (1010). Specifically, as illustrated in FIG. 23b (a), moisture can be introduced into the interior of the stylus pen (1000) through a first moisture inflow path (P1'), which is a path through which moisture passes through the core opening (not shown) of the housing (1010) and through the space between the housing (1010) and the inductor part (1200) to enter the interior of the stylus pen (1000). Alternatively, specifically, as shown in (b) of FIG. 23b, moisture may be introduced into the interior of the stylus pen (1000) through a second moisture inflow path (P2'), which is a path through which moisture passes through the core opening (not shown) of the housing (1010) and through the through hole of the ferrite core (1210) into the interior of the stylus pen (1000).

[0285] Referring to FIG. 24, the second moisture inflow path of the stylus pen illustrated in FIG. 3 is described in detail. FIG. 24 (a) shows the overall configuration of the stylus pen according to one embodiment of the present invention illustrated in FIG. 3 and the second moisture inflow path (P2'), and FIG. 24 (b) shows in detail the flow path of moisture introduced through the second moisture inflow path (P2') according to one embodiment of the present invention.

[0286] As illustrated in FIG. 24(a), a stylus pen according to one embodiment of the present invention may include a housing (1010), an inductor portion (1200) located inside the housing and comprising a ferrite core (1210) and a coil portion (1230) wound on the outer surface of the ferrite core (1210). The ferrite core (1210) may have a cylindrical, elliptical, or polygonal shape overall, and a through portion (1210h) penetrating the interior along the longitudinal direction of the ferrite core (1210) may be formed. The body portion of the core (1020) is capable of linear reciprocating motion along the longitudinal direction at the through portion (1210h) penetrating the interior of the ferrite core (1210).

[0287] Since the body portion of the core (1020) included in the stylus pen according to one embodiment of the present invention must be able to move along the longitudinal direction at the penetration portion (1210h), a space may be formed between the body portion of the core (1020) and the penetration portion (1210h). As shown in FIG. 24 (a), moisture may be introduced into the interior of the stylus pen through the second moisture inflow path (P2') through the space formed between the body portion of the core (1020) and the penetration portion (1210h).

[0288] As illustrated in FIG. 24 (a) and FIG. 24 (b), moisture introduced through the second moisture inflow path (P2') according to one embodiment of the present invention can pass through the space formed between the body part and the penetration part (1210h) of the core body (1020) and reach between the movable bracket (1300) and the core body (1020).

[0289] Meanwhile, according to one embodiment of the present invention, as shown in FIG. 5 and FIG. 14 (a), an electrical connection may be formed by contact between an electrode pattern (1390) formed on a movable bracket (1300) and an electrode pattern (1690) formed on a fixed bracket (1600) in a stylus pen according to one embodiment of the present invention. However, if moisture introduced through the second moisture inflow path (P2') reaches between the movable bracket (1300) and the core (1020), there is a risk that the electrical connection between the electrode pattern (1390) formed on the movable bracket (1300) and the electrode pattern (1690) formed on the fixed bracket (1600) may be interfered with. Accordingly, it is important to prevent moisture from entering through the second moisture inflow path (P2') through one or more sealing members according to one embodiment of the present invention, or to ensure that even if moisture enters, it does not interfere with the electrical connection between the electrode pattern (1390) formed on the movable bracket (1300) and the electrode pattern (1690) formed on the fixed bracket (1600). A description of the sealing member for preventing moisture from entering through at least one of the above-described first moisture inflow path (P1), first moisture inflow path (P1'), second moisture inflow path (P2), and second moisture inflow path (P2') will be provided later.

Additionally, the button bracket (1190) may have a predetermined groove (not shown) formed therein for coupling with a button portion (1090) so as to accommodate the button portion (1090).

[0294] As illustrated in FIG. 25 (a), moisture may be introduced into the interior of a stylus pen (1000) according to one embodiment of the present invention through a third moisture inflow path (P3'). Specifically, as illustrated in FIG. 25 (b), the third moisture inflow path (P3') may include a path (P3'-1) that passes through the space between the button portion (1090) and the housing (1010) and reaches the substrate (2100) through a hole (not shown) formed in the button bracket (1190). Alternatively, the third moisture inflow path (P3') may include a path (P3'-2) that passes through the space between the button portion (1090) and the housing (1010) and reaches the substrate (2100) along the outer surface of the button bracket (1190).

Additionally, the first sealing member (2000a') may be positioned to be in close contact with the inner wall of the housing (1010). By doing so, the first sealing member (2000a') can prevent moisture from entering through the first moisture inflow path (P1').

[0374] As described above with reference to FIGS. 32a and 32b, the third sealing member (2000c, 2000c') may be positioned to cover at least a portion of the outer surface of the ferrite core (1210). Specifically, the third sealing member (2000c, 2000c') may cover at least a portion of the outer surface of the ferrite core (1210) near the core opening (not shown). Additionally, the third sealing member (2000c) may be positioned to be in contact with the coil portion (1230), but is not limited thereto. Furthermore, the third sealing member (2000c, 2000c') may be positioned to be in close contact with the inner wall of the housing (1010). By doing so, the third sealing member (2000c, 2000c') can prevent moisture from entering through the first moisture inflow path (P1').

[0375] As described above with reference to FIG. 33, the stylus pen (1000) may include a cushioning member (1150). Specifically, the cushioning member (1150) may be positioned to cover at least a portion of the outer surface of each of the core (1020) and the ferrite core (1210) near the core opening (not shown).

[0376] Additionally, the cushioning member (1150) may include a fourth sealing member (2000d). Specifically, the fourth sealing member (2000d) may be formed in the shape of a ring, but is not limited thereto. The fourth sealing member (2000d) may be coupled to one end of the core opening (not shown) side of the cushioning member (1150).

[0377] More specifically, the fourth sealing member (2000d) may be intended to block the first moisture inflow path (P1'). As shown in FIG. 24 (b), the outer edge (2000d-1) of the fourth sealing member (2000d) may be positioned to be in close contact with the inner wall of the housing (1010). By doing so, the fourth sealing member (2000d) can prevent moisture from entering the first moisture inflow path (P1').

[0378] Additionally, the fourth sealing member (2000d) may be intended to block the second moisture inflow path (P2'). As shown in FIG. 24 (b), the inner rim (2000d'-2) of the fourth sealing member (2000d) may be positioned to be in close contact with the core (1020) and / or the ferrite core (1210). By doing so, the fourth sealing member (2000d) can prevent moisture from entering the second moisture inflow path (P2').

[0379] According to one embodiment of the present invention, the fourth sealing member (2000d) may be coupled to one end of the cushioning member (1150) as a separate component. Alternatively, the fourth sealing member (2000d) may be coupled to one end of the cushioning member (1150) to form an integral part with the cushioning member (1150). However, it is not limited thereto.

[0380] According to one embodiment of the present invention, the fourth sealing member (2000d) may be formed at one end of the cushioning member (1150) through a predetermined process. For example, the fourth sealing member (2000d) may be formed through at least one process selected from the group including a taping process and a coating process. However, it is not limited thereto.

[0381] As described above with reference to FIG. 35, a stylus pen (1000) according to one embodiment of the present invention may include a packing member (1290). Specifically, the packing member (1290) may be coupled to a button bracket (1190) through a predetermined groove (not shown) formed in the button bracket (1190). Additionally, the packing member (1290) may block a hole (not shown) formed in the button bracket (1190) to block a third moisture inflow path (P3'). The packing member (1290) may be positioned to be in close contact with the button bracket (1190).

[0382] Additionally, the packing member (1290) may have a protrusion (1291) formed on its edge. Specifically, the protrusion (1291) may be formed to be in close contact with the inner wall of the housing (1010).

[0383] Thus, the packing member (1290) can prevent moisture from entering through a third moisture inflow path (P3') that passes through the gap between the button part (1090) and the housing (1010) and reaches the substrate (2100) along a hole (not shown) formed in the button bracket (1190) or the outer surface of the button bracket (1190).

[0384] As described above with reference to FIGS. 36a and 36b, FIGS. 36e and 36f, a stylus pen (1000) according to one embodiment of the present invention may include a fifth sealing member (2000e, 2000e') for blocking a fourth moisture inflow path (P4'). Specifically, the fifth sealing member (2000e, 2000e') may be disposed in a groove (not shown) formed in the clicker cover (2400) near the portion where the clicker cover (2400) is coupled with the substrate bracket (1900). The fifth sealing member (2000e, 2000e') may wrap around the outer surface of the clicker cover (2400) in the groove (not shown) formed in the clicker cover (2400). Additionally, the fifth sealing member (2000e, 2000e') can be positioned to be in close contact with the inner wall of the housing (1010). By doing so, the fifth sealing member (2000e, 2000e') can prevent moisture from entering through the fourth moisture inflow path (P4').

[0385] As described above with reference to FIGS. 36c and 36d, FIGS. 36g and 36h, a stylus pen (1000) in one embodiment of the present invention may include a fifth sealing member (2000e, 2000e') for blocking a fourth moisture inflow path (P4'). Specifically, the fifth sealing member (2000e, 2000e') may be disposed in a groove (not shown) formed in the substrate bracket (1900) near the portion where the inner wall of the housing (1010) is joined to the substrate bracket (1900). The fifth sealing member (2000e, 2000e') may wrap around the outer surface of the substrate bracket (1900) in the groove (not shown) formed in the substrate bracket (1900). Additionally, the fifth sealing member (2000e, 2000e') can be positioned to be in close contact with the inner wall of the housing (1010). By doing so, the fifth sealing member (2000e, 2000e') can prevent moisture from passing through the joint between the housing (1010) and the substrate bracket (1900') and entering the fourth moisture inflow path (P4') which reaches the substrate (2100) along the outer surface of the substrate bracket (1900').

[0386] Accordingly, by applying at least one waterproofing means among a cushioning member (1150) comprising the above-described first sealing member (2000a, 2000a'), second sealing member (2000b), third sealing member (2000c, 2000c'), and fourth sealing member (2000d), a fifth sealing member (2000e, 2000e'), and a packing member (1290) to a stylus pen according to embodiments of the present invention, it is possible to prevent moisture from entering through at least one of a first moisture inflow path (P1'), a second moisture inflow path (P2'), a third moisture inflow path (P3'), and a fourth moisture inflow path (P4').

[0389] FIG. 38a is a drawing showing an embodiment of a sealing member that blocks a second moisture inflow path of a stylus pen according to one embodiment of the present invention. FIG. 38b is a drawing showing an embodiment of a sealing member that blocks a second moisture inflow path of a stylus pen according to another embodiment of the present invention. FIG. 38c is a drawing showing an embodiment of a sealing member that blocks a second moisture inflow path of a stylus pen according to another embodiment of the present invention. Referring to FIG. 38a to FIG. 38c, a stylus pen according to one embodiment of the present invention may include a sixth sealing member (2000f) for blocking a second moisture inflow path (P2'). Hereinafter, various embodiments of the sixth sealing member (2000f) for blocking the second moisture inflow path (P2') will be described with reference to the drawings.

[0390] First embodiment of the sixth sealing member

[0391] FIG. 38a is a drawing showing an embodiment of a sealing member that blocks a second moisture inflow path of a stylus pen according to an embodiment of the present invention.

[0392] Referring to FIG. 38a, a stylus pen according to one embodiment of the invention may include a core (1020), a fixed bracket (1600'), a movable bracket (1300'), a holder member (1500'), a first electrode pattern (1390'), a second electrode pattern (1690'), an elastic body (1700), a second movable member (1370'), an elastic member (1800), an inductor part including a magnetic body (1400) housed in the movable bracket (1300'), a ferrite core (1210), and a sixth sealing member (2000f) for blocking a second moisture inflow path (P2').

[0393] Referring to FIG. 38a, a sixth sealing member (2000f) according to one embodiment of the present invention can separate a first detection unit (D1) in which a magnetic body (1400) housed in a ferrite core (1210) and a moving bracket (1300') is located, and a second detection unit (D2) in which an elastic member (1800), a first electrode pattern (1390'), and a second electrode pattern (1690') are located. Meanwhile, according to one embodiment of the present invention, the first detection unit (D1) discussed with reference to FIG. 38a may include an inductor part, and the second detection unit (D2) may include a capacitor part. Additionally, the first detector (D1), discussed with reference to FIG. 38a, includes a magnetic body (1400) and a ferrite core (1210) for distinguishing a pressure state and / or detecting pressure, and the second detector (D2) may include a first electrode pattern (1390') and a second electrode pattern (1690') for distinguishing a contact state, and an elastic member (1800) for detecting or controlling pressure.

[0394] Referring to FIG. 38a, a holder member (1500') according to one embodiment of the present invention comprises an elastic material and can be positioned by being sandwiched between the other end of the core body (1020) and the movable bracket (1300'). The other end of the core body (1020) can be protected by the holder member (1500'), and since the holder member (1500') is sandwiched between the other end of the core body (1020) and the movable bracket (1300'), the movable bracket (1300') can be synchronized with the movement of the core body (1020). As shown in FIG. 38a, the holder member (1500') according to one embodiment of the present invention may include a portion protruding toward the sixth sealing member (2000f).

[0395] Similar to the holder member (1500) described with reference to (a) and (b) of FIG. 11b, the holder member (1500') may include an inner space in which the core body (1020) is located. The holder member (1500') according to one embodiment of the present invention is positioned between the movable bracket (1300') and the core body (1020) to prevent the core body (1020) from easily coming out with a force below a threshold value. For example, the core body (1020) may be pulled by the holder member (1500') with a force of about 100gf or more to come out, but the specific numerical value is merely an example and is not limited thereto. The function of such a holder member (1500') is designed so that excessive force is not required when attempting to detach the core body (1020) from the stylus pen, while providing stability that prevents the core body (1020) from unnecessarily coming out during use.

[0396] Meanwhile, a holder member (1500') according to one embodiment of the present invention may include an elastic material. By utilizing the elasticity of the holder member (1500'), the overlap dimension between the outer diameter of the core (1020) and the inner space of the holder member (1500') can be adjusted, thereby providing a stable fixing force to the core (1020) of the holder member (1500'). For example, even if the width of the inner space of the holder member (1500') is smaller than the outer diameter of the core (1020), the core (1020) can be fitted into the inner space of the holder member (1500') by the elasticity of the holder member (1500'), and the core (1020) can be stably fixed to the inner space of the holder member (1500').

[0397] In the case where the holder member (1500') according to one embodiment of the present invention includes an elastic material, a relatively large overlap dimension can be allowed due to the elasticity, thereby providing a high degree of design freedom. Furthermore, even if the dimension of at least one of the internal components of the stylus pen according to one embodiment of the present invention changes, the fixing force of the core body (1020) can be maintained at a constant level or, in some cases, flexibly adjusted due to the elasticity of the holder member (1500'), thus providing the advantage of increased freedom in the design and mass production process.

[0398] A first electrode pattern (1390') according to one embodiment of the present invention may be disposed on one side of a second moving member (1370'). Inside the elastic body (1700), the second moving member (1370') and at least a portion of the elastic member (1800) may be disposed together. This allows the internal space of the elastic body (1700) to be utilized, thereby providing the advantage of reducing the internal volume of the stylus pen.

[0399] A sixth sealing member (2000f) according to one embodiment of the present invention may be disposed inside a fixed bracket (1600'). According to one embodiment of the present invention, the sixth sealing member (2000f) may be configured to separate a first space in which the core body (1020) communicates with the movable bracket (1300') in synchronization, and a second space in which contact is formed between the first electrode pattern (1390') and the second electrode pattern (1690'). Here, the first space may be a space associated with the first detector (D1), and the second space may be a space associated with the second detector (D2).

[0400] According to one embodiment of the present invention, the sixth sealing member (2000f) may include an elastic material. Meanwhile, according to one embodiment of the present invention, the sixth sealing member (2000f) may be configured in the form of a diaphragm. According to one embodiment of the present invention, when the core body (1020) receives force in the longitudinal direction of the stylus pen, the core body (1020) may move in the direction of the force together with the synchronized moving bracket (1300'). Meanwhile, when the moving bracket (1300') moves in the direction of the force, the sixth sealing member (2000f) may also receive force in the longitudinal direction of the stylus pen through contact formed between the holder member (1500') and the sixth sealing member (2000f).

[0401] According to one embodiment of the present invention, the sixth sealing member (2000f) includes an elastic material, so that the shape may be deformed in the longitudinal direction of the stylus pen due to the elasticity, and due to the shape deformation, the movable bracket (1300') can move further in the longitudinal direction of the stylus pen. Contact may be formed between the sixth sealing member (2000f) and the second movable member (1370') by the additional movement of the movable bracket (1300'), and the second movable member (1370') may also receive force in the longitudinal direction of the stylus pen. When the second movable member (1370') moves in the longitudinal direction due to a predetermined force applied to the extension part (1370'), the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') may be broken. In this way, the sixth sealing member (2000f) separates the first space and the second space, so that moisture introduced through the second moisture inflow path (P2') can be prevented or minimized from penetrating the contact portion formed between the first electrode pattern (1390') and the second electrode pattern (1690').

[0402] Meanwhile, according to one embodiment of the present invention, when an external force is applied to the core (1020) in the longitudinal direction of the stylus pen, the applied force is transmitted to the sixth sealing member (2000f) through the holder member (1500'), and since it is desirable to cause movement of the first electrode pattern (1390') through the sixth sealing member (2000f), contact can be formed between the sixth sealing member (2000f) and the second moving member (1370'). Referring to FIG. 38a, the second moving member (1370') on which the first electrode pattern (1390') is formed may include a protrusion protruding toward the sixth sealing member (2000f). Accordingly, the sixth sealing member (2000f) and the second moving member (1370') may come into contact with each other, and the first electrode pattern (1390') may be moved by a force applied in the longitudinal direction of the stylus pen. Meanwhile, FIG. 38a is illustrated as including a protrusion on the second moving member (1370') according to one embodiment of the present invention, but is not limited thereto. The sixth sealing member (2000f) may include a protrusion protruding toward the second moving member (1370'), or both the sixth sealing member (2000f) and the second moving member (1370') may include protrusions protruding toward each other, or the sixth sealing member (2000f) and the second moving member (1370') may be configured to come into contact with each other without a separate protrusion.

[0403]

[0404] Second embodiment of the sixth sealing member

[0405] FIG. 38b is a drawing showing an embodiment of a sealing member that blocks a second moisture inflow path of a stylus pen according to another embodiment of the present invention.

[0406] Referring to FIG. 38b, a stylus pen according to one embodiment of the invention may include a core (1020), a fixed bracket (1600'), a movable bracket (1300''), a holder member (1500''), a first electrode pattern (1390'), a second electrode pattern (1690'), an elastic body (1700), a second movable member (1370'), an elastic member (1800), an inductor part including a magnetic body (1400') housed in the movable bracket (1300''), a ferrite core (1210), and a sixth sealing member (2000f) for blocking a second moisture inflow path (P2').

[0407] Referring to FIG. 38b, a sixth sealing member (2000f) according to one embodiment of the present invention can separate a first detection unit (D1) in which a magnetic body (1400') housed in a ferrite core (1210) and a moving bracket (1300'') is located, and a second detection unit (D2) in which an elastic member (1800), a first electrode pattern (1390'), and a second electrode pattern (1690') are located. Meanwhile, according to one embodiment of the present invention, the first detection unit (D1) discussed with reference to FIG. 38b may include an inductor part, and the second detection unit (D2) may include a capacitor part. Additionally, the first detector (D1), discussed with reference to FIG. 38b, includes a magnetic body (1400') and a ferrite core (1210) for distinguishing a pressure state and / or detecting pressure, and the second detector (D2) may include a first electrode pattern (1390') and a second electrode pattern (1690') for distinguishing a contact state, and an elastic member (1800) for detecting or controlling pressure.

[0408] Referring to FIG. 38b, a moving bracket (1300'') according to one embodiment of the present invention moves together with the core body (1020) in synchronization. When one end of the core body (1020) receives an external force from the outside, the core body (1020) moves into the inside of the housing of the stylus pen, and the moving bracket (1300'') can move together with the core body (1020). The moving bracket (1300'') is configured to accommodate the other end of the core body (1020), a magnetic body (1400'), and a holder member (1500''). The moving bracket (1300'') may have a storage portion that accommodates the other end of the core body (1020), a magnetic body (1400'), and a holder member (1500''). That is, referring to FIG. 38a and FIG. 38b, the movable bracket (1300'') shown in FIG. 38b can perform at least some of the roles and functions of the movable bracket (1300') shown in FIG. 38a. Meanwhile, the movable bracket (1300'') according to one embodiment of the present invention may include a portion protruding toward the sixth sealing member (2000f).

[0409] FIG. 11c (a) and (b) illustrate a holder member (1500'') according to an embodiment of the present invention. Referring to FIG. 11c (a) and (b) and FIG. 38b, the holder member (1500'') according to an embodiment of the present invention comprises an elastic material and can be positioned by being sandwiched between the other end of the core body (1020) and the movable bracket (1300''). The other end of the core body (1020) can be protected by the holder member (1500''), and since the holder member (1500'') is sandwiched between the other end of the core body (1020) and the movable bracket (1300''), the movable bracket (1300'') can be synchronized with the movement of the core body (1020). A holder member (1500'') according to one embodiment of the present invention may include a protrusion located within a groove of a movable bracket (1300''), as shown in FIG. 38b. Since the protrusion of the holder member (1500'') is located within a groove of the movable bracket (1300''), the holder member (1500'') can be more firmly fixed to the movable bracket (1300'').

[0410] Referring to FIG. 11c (a) and (b), a holder member (1500'') according to one embodiment of the present invention may include an inner space in which a core body (1020) is located. A holder member (1500'') according to one embodiment of the present invention is positioned between a movable bracket (1300'') and a core body (1020) to prevent the core body (1020) from easily coming out with a force below a threshold value. For example, the core body (1020) may be pulled by the holder member (1500'') with a force of about 100gf or more to come out, but the specific numerical value is merely an example and is not limited thereto. The function of such a holder member (1500'') is designed so that excessive force is not required when attempting to detach the core body (1020) from the stylus pen, while providing stability that prevents the core body (1020) from unnecessarily coming out during use.

[0411] Meanwhile, the holder member (1500'') according to one embodiment of the present invention may include an elastic material. By utilizing the elasticity of the holder member (1500''), the overlap dimension between the outer diameter of the core body (1020) and the inner space of the holder member (1500'') can be adjusted, thereby providing a stable fixing force to the core body (1020) of the holder member (1500''). For example, even if the width of the inner space of the holder member (1500'') is smaller than the outer diameter of the core body (1020), the core body (1020) can be fitted into the inner space of the holder member (1500'') by the elasticity of the holder member (1500''), and the core body (1020) can be stably fixed to the inner space of the holder member (1500'').

[0412] In the case where the holder member (1500'') according to one embodiment of the present invention includes an elastic material, a relatively large overlap dimension can be allowed due to the elasticity, thereby providing a high degree of design freedom. Furthermore, even if the dimension of at least one of the internal components of the stylus pen according to one embodiment of the present invention changes, the fixing force of the core body (1020) can be maintained at a constant level or, in some cases, flexibly adjusted due to the elasticity of the holder member (1500''), thus providing the advantage of increased freedom in the design and mass production process.

[0413] The holder member (1500'') may include a protrusion (1510'') that protrudes outward from the outer surface, as shown in (a) and (b) of FIG. 11c. The protrusion (1510'') may be fitted into an insertion groove (not shown) formed in the movable bracket (1300''). By means of the protrusion (1510'') of the holder member (1500'') and the insertion groove of the movable bracket (1300''), the holder member (1500'') can be stably fixed to the movable bracket (1300''), and accordingly, the other end of the core body (1020) can be fixed to the movable bracket (1300'').

[0414] In a stylus pen according to one embodiment of the present invention, since the core body (1020) is fixed to the movable bracket (1300'') by the holder member (1500''), when a force is applied to one end of the core body and the core body (1020) moves, the movable bracket (1300'') also moves together, and the movable bracket (1300'') pushes the second movable member (1370'), causing the first electrode pattern (1390') included in the second movable member (1370') to move together. Since the movement of the core body (1020) and the movement of the movable bracket (1300'') are synchronized, the movement of the movable bracket (1300'') linked with the core body (1020) has the effect of reducing the error in the electrical contact and release operation between the first electrode pattern (1390') of the second movable member (1370') and the second electrode pattern (1690') of the fixed bracket (1600').

[0415] A first electrode pattern (1390') according to one embodiment of the present invention may be disposed on one side of a second moving member (1370'). Inside the elastic body (1700), the second moving member (1370') and at least a portion of the elastic member (1800) may be disposed together. This allows the internal space of the elastic body (1700) to be utilized, thereby providing the advantage of reducing the internal volume of the stylus pen.

[0416] A sixth sealing member (2000f) according to one embodiment of the present invention may be disposed inside a fixed bracket (1600'). According to one embodiment of the present invention, the sixth sealing member (2000f) may be configured to separate a first space in which the core body (1020) communicates with the movable bracket (1300'') in synchronization, and a second space in which contact is formed between the first electrode pattern (1390') and the second electrode pattern (1690'). Here, the first space may be a space associated with the first detector (D1), and the second space may be a space associated with the second detector (D2).

[0417] According to one embodiment of the present invention, the sixth sealing member (2000f) may include an elastic material. Meanwhile, according to one embodiment of the present invention, the sixth sealing member (2000f) may be configured in the form of a diaphragm. According to one embodiment of the present invention, when the core body (1020) receives a force in the longitudinal direction of the stylus pen, the core body (1020) may move in the direction of the force together with the synchronized moving bracket (1300''). Meanwhile, when the moving bracket (1300'') moves in the direction of the force, the sixth sealing member (2000f) may also receive a force in the longitudinal direction of the stylus pen through the contact formed between the moving bracket (1300'') and the sixth sealing member (2000f).

[0418] According to one embodiment of the present invention, the sixth sealing member (2000f) includes an elastic material, so that the shape may be deformed in the longitudinal direction of the stylus pen due to the elasticity, and due to the shape deformation, the movable bracket (1300'') can move further in the longitudinal direction of the stylus pen. Contact may be formed between the sixth sealing member (2000f) and the second movable member (1370') by the additional movement of the movable bracket (1300''), and the second movable member (1370') may also receive force in the longitudinal direction of the stylus pen. When the second movable member (1370') moves in the longitudinal direction due to a predetermined force applied to the extension part (1370'), the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') may be broken. In this way, the sixth sealing member (2000f) separates the first space and the second space, so that moisture introduced through the second moisture inflow path (P2') can be prevented or minimized from penetrating the contact portion formed between the first electrode pattern (1390') and the second electrode pattern (1690').

[0419] Meanwhile, according to one embodiment of the present invention, when an external force is applied to the core (1020) in the longitudinal direction of the stylus pen, the applied force is transmitted to the sixth sealing member (2000f) through the moving bracket (1300''), and since it is desirable to cause movement of the first electrode pattern (1390') through the sixth sealing member (2000f), contact can be formed between the sixth sealing member (2000f) and the second moving member (1370'). Referring to FIG. 38b, the second moving member (1370') on which the first electrode pattern (1390') is formed may include a protrusion protruding toward the sixth sealing member (2000f). Accordingly, the sixth sealing member (2000f) and the second moving member (1370') can come into contact with each other, and the first electrode pattern (1390') can be moved by the force applied in the longitudinal direction of the stylus pen. Meanwhile, FIG. 38b is illustrated as including a protrusion on the second moving member (1370') according to one embodiment of the present invention, but is not limited thereto, and the sixth sealing member (2000f) may include a protrusion protruding toward the second moving member (1370'), or both the sixth sealing member (2000f) and the second moving member (1370') may include protrusions protruding toward each other, or the sixth sealing member (2000f) and the second moving member (1370') may be configured to come into contact with each other without a separate protrusion.

[0421] Third embodiment of the sixth sealing member

[0422] FIG. 38c is a drawing showing an embodiment of a sealing member that blocks a second moisture inflow path of a stylus pen according to another embodiment of the present invention.

[0423] Referring to FIG. 38c, a stylus pen according to one embodiment of the invention may include a core (1020), a fixed bracket (1600'), a movable bracket (1300'''), a holder member (1500''), a first electrode pattern (1390'), a second electrode pattern (1690'), an elastic body (1700), a second movable member (1370'), an elastic member (1800'), an inductor part including a magnetic body (1400') housed in the movable bracket (1300'''), a ferrite core (1210), and a sixth sealing member (2000f) for blocking a second moisture inflow path (P2').

[0424] Referring to FIG. 38c, a sixth sealing member (2000f) according to one embodiment of the present invention can separate from each other a first detection unit (D1) in which a ferrite core (1210), a magnetic body (1400') housed in a movable bracket (1300'''), and an elastic member (1800') are located, and a second detection unit (D2) in which a first electrode pattern (1390') and a second electrode pattern (1690') are located. Meanwhile, according to one embodiment of the present invention, the first detection unit (D1) discussed with reference to FIG. 38c may include an inductor part, and the second detection unit (D2) may include a capacitor part. Additionally, the first detector (D1), discussed with reference to FIG. 38c, includes a magnetic body (1400') and a ferrite core (1210) for distinguishing a pressure state and / or detecting pressure, and an elastic member (1800') for detecting or controlling pressure, and the second detector (D2) may include a first electrode pattern (1390') and a second electrode pattern (1690') for distinguishing a contact state.

[0425] Referring to FIG. 38c, a moving bracket (1300''') according to one embodiment of the present invention moves together with the core body (1020) in synchronization. When one end of the core body (1020) receives an external force from the outside, the core body (1020) moves into the inside of the housing of the stylus pen, and the moving bracket (1300''') can move together with the core body (1020). The moving bracket (1300''') is configured to accommodate the other end of the core body (1020), a magnetic body (1400'), and a holder member (1500''). The moving bracket (1300'') may have a storage portion that accommodates the other end of the core body (1020), a magnetic body (1400'), and a holder member (1500''). That is, referring to FIG. 38b and FIG. 38c, the movable bracket (1300''') shown in FIG. 38c can perform at least some of the roles and functions of the movable bracket (1300'') shown in FIG. 38b.

[0426] Meanwhile, referring to FIG. 38c, an elastic member (1800') according to one embodiment of the present invention may be disposed between a movable bracket (1300''') and a sixth sealing member (2000f). The elastic member (1800') may include an elastic material and be configured to be coupled to the movable bracket (1300''') to form contact with the sixth sealing member (2000f), but is not limited thereto, and the elastic member (1800') may also be configured to be coupled to the sixth sealing member (2000f) to form contact with the movable bracket (1300''').

[0427] FIG. 11c (a) and (b) illustrate a holder member (1500'') according to an embodiment of the present invention. Referring to FIG. 11c (a) and (b) and FIG. 38c, the holder member (1500'') according to an embodiment of the present invention comprises an elastic material and can be positioned by being sandwiched between the other end of the core body (1020) and the movable bracket (1300'''). The other end of the core body (1020) can be protected by the holder member (1500''), and since the holder member (1500'') is sandwiched between the other end of the core body (1020) and the movable bracket (1300'''), the movable bracket (1300''') can be synchronized with the movement of the core body (1020). Although not illustrated in FIG. 38c, a holder member (1500'') according to one embodiment of the present invention may include a protrusion located within a groove of a movable bracket (1300'''), as illustrated in FIG. 38b. Since the protrusion of the holder member (1500'') is located within a groove of the movable bracket (1300'''), the holder member (1500'') can be more firmly fixed to the movable bracket (1300'').

[0428] A first electrode pattern (1390') according to one embodiment of the present invention may be disposed on one side of a second moving member (1370'). A second moving member (1370') may be disposed inside an elastic body (1700). This allows the internal space of the elastic body (1700) to be utilized, thereby providing the advantage of reducing the internal volume of the stylus pen.

[0429] A sixth sealing member (2000f) according to one embodiment of the present invention may be disposed inside a fixed bracket (1600'). According to one embodiment of the present invention, the sixth sealing member (2000f) may be configured to separate a first space in which the core body (1020) communicates in synchronization with a movable bracket (1300''') and a second space in which contact is formed between a first electrode pattern (1390') and a second electrode pattern (1690'). Here, the first space may be a space associated with a first detector (D1), and the second space may be a space associated with a second detector (D2).

[0430] According to one embodiment of the present invention, the sixth sealing member (2000f) may include an elastic material. Meanwhile, according to one embodiment of the present invention, the sixth sealing member (2000f) may be configured in the form of a diaphragm. According to one embodiment of the present invention, when the core body (1020) receives a force in the longitudinal direction of the stylus pen, the core body (1020) may move in the direction of the force together with the synchronized moving bracket (1300'''). Meanwhile, when the moving bracket (1300''') moves in the direction of the force, the sixth sealing member (2000f) may also receive a force in the longitudinal direction of the stylus pen through contact formed between the elastic member (1800') and the sixth sealing member (2000f).

[0431] According to one embodiment of the present invention, the sixth sealing member (2000f) includes an elastic material, so that the shape may be deformed in the longitudinal direction of the stylus pen due to the elasticity, and due to the shape deformation, the movable bracket (1300''') can move further in the longitudinal direction of the stylus pen. Contact may be formed between the sixth sealing member (2000f) and the second movable member (1370') by the additional movement of the movable bracket (1300'''), and the second movable member (1370') may also receive force in the longitudinal direction of the stylus pen. When the second movable member (1370') moves in the longitudinal direction due to a predetermined force applied to the extension part (1370'), the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') may be broken. In this way, the sixth sealing member (2000f) separates the first space and the second space, so that moisture introduced through the second moisture inflow path (P2') can be prevented or minimized from penetrating the contact portion formed between the first electrode pattern (1390') and the second electrode pattern (1690').

[0432] Meanwhile, according to one embodiment of the present invention, when an external force is applied to the core (1020) in the longitudinal direction of the stylus pen, the applied force is transmitted to the sixth sealing member (2000f) through the moving bracket (1300''') and the elastic member (1800'), and since it is desirable to cause movement of the first electrode pattern (1390') through the sixth sealing member (2000f), contact can be formed between the sixth sealing member (2000f) and the second moving member (1370'). Referring to FIG. 38c, the second moving member (1370') on which the first electrode pattern (1390') is formed may include a protrusion protruding toward the sixth sealing member (2000f). Accordingly, the sixth sealing member (2000f) and the second moving member (1370') may come into contact with each other, and the first electrode pattern (1390') may be moved by a force applied in the longitudinal direction of the stylus pen. Meanwhile, FIG. 38c is illustrated as including a protrusion on the second moving member (1370') according to one embodiment of the present invention, but is not limited thereto, and the sixth sealing member (2000f) may include a protrusion protruding toward the second moving member (1370'), or both the sixth sealing member (2000f) and the second moving member (1370') may include protrusions protruding toward each other, or the sixth sealing member (2000f) and the second moving member (1370') may be configured to come into contact with each other without a separate protrusion.

[0434] Operation of a stylus pen including a sixth sealing member

[0435] FIG. 39a is a drawing for explaining the operation of an internal configuration according to the movement of a core body in a stylus pen including a sixth sealing member illustrated in FIG. 38a. FIG. 39b is a drawing for explaining the operation of an internal configuration according to the movement of a core body in a stylus pen including a sixth sealing member illustrated in FIG. 38b. FIG. 39c is a drawing for explaining the operation of an internal configuration according to the movement of a core body in a stylus pen including a sixth sealing member illustrated in FIG. 38c. FIG. 40 is a drawing for explaining electrical contact and release of contact between a first electrode pattern (1390') and a second electrode pattern (1690') according to the movement of a core body (1020) in a stylus pen illustrated in FIG. 39a to FIG. 39c. Hereinafter, the operation of a stylus pen including a sixth sealing member according to embodiments of the present invention will be described in detail with reference to the drawings.

[0436] FIGS. 39a(a), FIGS. 39b(a), FIGS. 39c(a) and FIGS. 40(a) illustrate the case where no external force is applied to the core body (1020) of the stylus pen, and FIGS. 39a(b), FIGS. 39b(b), FIGS. 39c(b) and FIGS. 40(b) illustrate the case where an external force is applied to the core body (1020) of the stylus pen in the longitudinal direction.

[0437] First, referring to (a) of FIG. 39a, when no external force is applied to the core body (1020) shown in FIG. 38a, the first electrode pattern (1390') comes into contact with the second electrode pattern (1690'). That is, the first electrode pattern (1390') and the second electrode pattern (1690') are electrically connected to each other. According to one embodiment of the present invention, an elastic body (1700) can be fitted in a partially compressed state while wrapping around the second movable member (1370'). Because the second movable member (1370') is pushed toward the core body (1020) by the partially compressed elastic body (1700), the first electrode pattern (1390') can maintain contact with the second electrode pattern (1690').

[0438] Referring to (a) of FIG. 39a, if the external force applied to the core body (1020) and transmitted to the second moving member (1370') through the moving bracket (1300') and holder member (1500'), which are synchronized with the movement of the core body (1020), is smaller than the elastic force that causes the partially compressed elastic body (1700) to push the second moving member (1370') outward, then the elastic body (1700) is not compressed, and the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') is not broken. Meanwhile, according to one embodiment of the present invention, in a state where the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') is not broken, there is no change in the internal components, and no change in position between the magnetic body (1400) and the inductor part occurs, so the inductance (L) value can be maintained at a constant level. In addition, the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') is not interrupted, so the capacitance (C) value of the capacitor section can also be maintained at a constant level. Accordingly, the resonance frequency of the resonance circuit can be maintained at a constant level.

[0439] Meanwhile, referring to (b) of FIG. 39a, if the external force transmitted to the second moving member (1370') through the moving bracket (1300') and holder member (1500') synchronized with the movement of the core body (1020) is greater than the elastic force that pushes the second moving member (1370') outward by the partially compressed elastic body (1700), the elastic body (1700) is compressed by the external force transmitted through the sixth sealing member (2000f), and the second moving member (1370') moves in the same direction as the external force, and as a result, the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') is broken.

[0440] Next, referring to (a) of FIG. 39b, when no external force is applied to the core body (1020) illustrated in FIG. 38b, the first electrode pattern (1390') comes into contact with the second electrode pattern (1690'). That is, the first electrode pattern (1390') and the second electrode pattern (1690') are electrically connected to each other. According to one embodiment of the present invention, an elastic body (1700) can be fitted in a partially compressed state while wrapping around the second movable member (1370'). The second movable member (1370') is pushed toward the core body (1020) by the partially compressed elastic body (1700), so that the first electrode pattern (1390') can remain in contact with the second electrode pattern (1690').

[0441] Referring to (a) of FIG. 39b, if the external force applied to the core body (1020) and transmitted to the second moving member (1370') through the moving bracket (1300'') which is synchronized with the movement of the core body (1020) is smaller than the elastic force that causes the partially compressed elastic body (1700) to push the second moving member (1370') outward, the elastic body (1700) is not compressed, and the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') is not broken. Meanwhile, according to one embodiment of the present invention, in a state where the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') is not broken, there is no change in the internal components, and no change in position between the magnetic body (1400) and the inductor part occurs, so the inductance (L) value can be maintained at a constant level. In addition, the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') is not interrupted, so the capacitance (C) value of the capacitor section can also be maintained at a constant level. Accordingly, the resonance frequency of the resonance circuit can be maintained at a constant level.

[0442] Meanwhile, referring to (b) of FIG. 39b, if the external force transmitted to the second moving member (1370') through the moving bracket (1300'') synchronized with the movement of the core body (1020) is greater than the elastic force that pushes the second moving member (1370') outward by the partially compressed elastic body (1700), the elastic body (1700) is compressed by the external force transmitted through the sixth sealing member (2000f), and the second moving member (1370') moves in the same direction as the external force, and as a result, the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') is broken.

[0443] Next, referring to (a) of FIG. 39c, when no external force is applied to the core body (1020) illustrated in FIG. 38c, the first electrode pattern (1390') comes into contact with the second electrode pattern (1690'). That is, the first electrode pattern (1390') and the second electrode pattern (1690') are electrically connected to each other. According to one embodiment of the present invention, an elastic body (1700) can be fitted in a partially compressed state while wrapping around the second movable member (1370'). The second movable member (1370') is pushed toward the core body (1020) by the partially compressed elastic body (1700), so that the first electrode pattern (1390') can remain in contact with the second electrode pattern (1690').

[0444] Referring to (a) of FIG. 39c, when the external force applied to the core body (1020) and transmitted to the second moving member (1370') through the moving bracket (1300''') and elastic member (1800') which are synchronized with the movement of the core body (1020) is smaller than the elastic force that causes the partially compressed elastic body (1700) to push the second moving member (1370') outward, the elastic body (1700) is not compressed, and the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') is not broken. Meanwhile, according to one embodiment of the present invention, when the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') is not broken, there is no change in the internal components, and no change in position between the magnetic body (1400') and the inductor part occurs, so the inductance (L) value can be maintained at a constant level. In addition, the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') is not interrupted, so the capacitance (C) value of the capacitor section can also be maintained at a constant level. Accordingly, the resonance frequency of the resonance circuit can be maintained at a constant level.

[0445] Meanwhile, referring to (b) of FIG. 39c, if the external force transmitted to the second moving member (1370') through the moving bracket (1300''') and elastic member (1800') synchronized with the movement of the core body (1020) is greater than the elastic force that pushes the second moving member (1370') outward by the partially compressed elastic body (1700), the elastic body (1700) is compressed by the external force transmitted through the sixth sealing member (2000f), and the second moving member (1370') moves in the same direction as the external force, and as a result, the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') is broken.

[0446] Referring to FIGS. 40 (a) and (b), a plurality of capacitors (C1, C2, C3, Cs) may be disposed on a substrate (2100) according to one embodiment of the present invention. The plurality of capacitors (C1, C2, C3, Cs) may constitute a capacitor section (not shown). At least one of the plurality of capacitors (C1, C2, C3, Cs) may be connected in parallel with each other to maintain a constant capacitance value, and an auxiliary capacitor (Cs) may be connected in parallel with the primary capacitor or not connected to the primary capacitor depending on contact or disconnection between the first electrode pattern (1390') and the second electrode pattern (1690') shown in FIGS. 39a to 39c.

[0447] First, as shown in FIG. 40 (a), when no external force is applied to the core body (1020) shown in FIG. 39a to 39c, the second electrode pattern (1690') and the first electrode pattern (1390') are in contact with each other, so the auxiliary capacitor (Cs) is connected in parallel with the basic capacitors (C1, C2, C3). Therefore, the capacitance (C) of the capacitor section (not shown) becomes the sum of the capacitance values ​​of the basic capacitors (C1, C2, C3) and the capacitance of the auxiliary capacitor (Cs).

[0448] Next, as illustrated in FIG. 40 (b), when a predetermined external force is applied to the core body (1020) illustrated in FIG. 39a to 39c, at least a portion of the external force can be transmitted to the second moving member (1370') through the sixth sealing member (2000f) by the movement of the core body (1020). Due to the force applied to the second moving member (1370'), the second moving member (1370') undergoes displacement in the direction of the external force, and accordingly, the first electrode pattern (1390') can be released from contact with the second electrode pattern (1690'). Consequently, the auxiliary capacitor (Cs) is not electrically connected to the basic capacitor (C1, C2, C3), and the capacitance (C) of the capacitor part (not shown) is changed to the capacitance value of the basic capacitor (C1, C2, C3).

[0449] As discussed with reference to FIG. 40(b), when the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') is broken, the auxiliary capacitor (Cs) is electrically disconnected from the plurality of primary capacitors, causing a change in the capacitance (C) value. In this case, the inductance (L) value of the inductor part may change as the core body (1020) moves. That is, as illustrated in FIG. 39a(b), FIG. 39b(b), and FIG. 39c(b), when a predetermined external force is applied to the core body (1020) and the core body (1020) moves in one direction, the contact between the first electrode pattern (1390') and the second electrode pattern (1690') may be released. Due to the release of the contact, the capacitance of the capacitor part mounted on the substrate (2100) changes rapidly. The abrupt change in the above capacitance changes the frequency of the pen signal emitted from the stylus pen. The receiving side receiving the pen signal can detect the changed frequency and determine that the stylus pen has made contact with the screen.

[0450] Hereinafter, stylus movements according to the movement of the core body to distinguish hover, contact, pressure, and button states according to the movement of the core body, according to an embodiment of the present invention, will be explained.

[0451] In the hover state, the touch input device may not receive a signal from the stylus pen, or even if a signal is received, it may be recognized that the stylus pen is not in contact with the touch input device. For example, as discussed with reference to FIGS. 39a to 39c, if no external force is applied to the core body (1020), or if the magnitude of the external force applied to the core body (1020) is smaller than the elastic force that causes the partially compressed elastic body (1700) to push the second moving member (1370') outward, it may be recognized as a hover state (H).

[0452] Specifically, referring to FIG. 39a (a), FIG. 39b (a), and FIG. 39c (a), when no external force is applied to the core body (1020), it can be recognized as being in a hover state. In this case, there is no change in the internal components. There is no deformation of the shape of the sixth sealing member (2000f), and the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') is not broken. There is no change in position between the magnetic body (1400, 1400') and the inductor part, so the inductance (L) value is maintained constant. Therefore, the inductance (L) value of the inductor part and the capacitance (C) value of the capacitor part are each maintained constant, so the resonance frequency of the resonance circuit is maintained constant.

[0453] Referring to FIG. 39a (a), FIG. 39b (a), and FIG. 39c (a), even if a predetermined external force is applied to one end of the core body (1020) in a hover state, the hover state can be recognized if the magnitude of the predetermined external force applied here is smaller than the magnitude of the elastic force that pushes the second moving member (1370') outward by the compressed elastic body (1700). Since the predetermined external force applied to the core body (1020) is smaller than the magnitude of the elastic force of the elastic body (1700), the elastic body (1700) is not compressed, and since no movement of the moving bracket (1300', 1300'') occurs, there is no change in the internal components. Since no deformation of the shape of the sixth sealing member (2000f) occurs and the electrical connection between the first electrode pattern (1390') and the second electrode pattern (1690') is not broken, no change in the capacitance (C) value of the capacitor part occurs. In addition, no change in position occurs between the magnetic material (1400, 1400') and the inductor part, so the inductance (L) value is maintained constant. Therefore, the inductance (L) value of the inductor part and the capacitance (C) value of the capacitor part are each maintained constant, so the resonance frequency of the resonance circuit is maintained constant.

[0454] In a contact state, a signal from the stylus pen is received by the touch input device, and the stylus pen can be recognized as having come into contact with the touch input device. For example, if the magnitude of the external force applied to the core body (1020) is greater than or equal to the elastic force that pushes the second moving member (1370') outward by the compressed elastic body (1700), it can be recognized as being in a contact state.

[0455] Meanwhile, referring to (b) of FIG. 39a, an external force is applied to the core body (1020) in a contact state, and the applied external force can be transmitted to the second moving member (1370') through the moving bracket (1300') and the holder member (1500') synchronized with the movement of the core body (1020), and through the sixth sealing member (2000f). Since the external force transmitted to the second moving member (1370') is greater than or equal to the elastic force of the compressed elastic body (1700) pushing the second moving member (1370') outward, a deformation of the shape in the longitudinal direction of the stylus pen may occur in the sixth sealing member (2000f) containing an elastic material. Due to the deformation of the sixth sealing member (2000f) in the longitudinal direction of the stylus pen, the second moving member (1370') is pushed in the longitudinal direction of the stylus pen, thereby releasing the contact between the first electrode pattern (1390') and the second electrode pattern (1690'). When the contact between the first electrode pattern (1390') and the second electrode pattern (1690') is released, as shown in FIG. 39a (b) and FIG. 40 (b), due to the release of contact, the auxiliary capacitor (C1, C2, C3) that was connected in parallel with the basic capacitors (C1, C2, C3) in the capacitor part (not shown) mounted on the substrate (2100) S Since the electrical connection of ) is broken, the total capacitance value of the capacitor part (not shown) decreases.

[0456] Next, referring to (b) of FIG. 39b, an external force is applied to the core body (1020) in a contact state, and the applied external force can be transmitted to the second moving member (1370') through a moving bracket (1300'') synchronized with the movement of the core body (1020) and through the sixth sealing member (2000f). Since the external force transmitted to the second moving member (1370') is greater than or equal to the elastic force of the compressed elastic body (1700) pushing the second moving member (1370') outward, a deformation in the longitudinal direction of the stylus pen may occur in the sixth sealing member (2000f) containing an elastic material. Due to the deformation of the sixth sealing member (2000f) in the longitudinal direction of the stylus pen, the second moving member (1370') is pushed in the longitudinal direction of the stylus pen, thereby releasing the contact between the first electrode pattern (1390') and the second electrode pattern (1690'). When the contact between the first electrode pattern (1390') and the second electrode pattern (1690') is released, as shown in FIG. 39b (b) and FIG. 40 (b), due to the release of contact, the auxiliary capacitor (C1, C2, C3) that was connected in parallel with the basic capacitors (C1, C2, C3) in the capacitor part (not shown) mounted on the substrate (2100) S Since the electrical connection of ) is broken, the total capacitance value of the capacitor part (not shown) decreases.

[0457] Next, referring to (b) of FIG. 39c, an external force is applied to the core body (1020) in a contact state, and the applied external force can be transmitted to the second moving member (1370') through the moving bracket (1300''') and elastic member (1800') synchronized with the movement of the core body (1020), and through the sixth sealing member (2000f). Since the external force transmitted to the second moving member (1370') is greater than or equal to the elastic force of the compressed elastic body (1700) pushing the second moving member (1370') outward, a deformation in the longitudinal direction of the stylus pen may occur in the sixth sealing member (2000f) containing an elastic material. Due to the deformation of the sixth sealing member (2000f) in the longitudinal direction of the stylus pen, the second moving member (1370') is pushed in the longitudinal direction of the stylus pen, thereby releasing the contact between the first electrode pattern (1390') and the second electrode pattern (1690'). When the contact between the first electrode pattern (1390') and the second electrode pattern (1690') is released, as shown in FIG. 39c (b) and FIG. 40 (b), due to the release of contact, the auxiliary capacitor (C1, C2, C3) that was connected in parallel with the basic capacitors (C1, C2, C3) in the capacitor part (not shown) mounted on the substrate (2100) S Since the electrical connection of ) is broken, the total capacitance value of the capacitor part (not shown) decreases.

[0458] Meanwhile, in a contact state according to an embodiment of the present invention discussed with reference to FIG. 39c(b) and FIG. 39c(b), the elastic member (1800) may be compressed and undergo shape deformation by an external force transmitted from the movable bracket (1300', 1300'') linked to the core body (1020), through the sixth sealing member (2000f), and through the second movable member (1370'). Due to the shape deformation of the elastic member (1800), a predetermined displacement occurs in the movable bracket (1300', 1300''), and a displacement also occurs in the magnetic body (1400, 1400') housed in the movable bracket (1300', 1300''). The inductance (L) value of the inductor part changes according to the displacement of the magnetic body (1400, 1400'). Therefore, in this case, the total capacitance value of the capacitor section (not shown) and the inductance (L) value of the inductor section change together, and the resonant frequency of the resonant circuit can be varied. In the contact state (c), the total capacitance value and the inductance value change together, but the change in the capacitance value may be greater than the change in the inductance value. In this case, the change in the capacitance value may have a dominant effect on the change in the LC value.

[0459] Meanwhile, in a contact state according to an embodiment of the present invention discussed with reference to FIG. 39c (b), the elastic member (1800') receives an external force from a movable bracket (1300''') linked to the core body (1020), and may be compressed and undergo shape deformation. Due to the shape deformation of the elastic member (1800'), a certain displacement occurs in the movable bracket (1300'''), and a displacement also occurs in the magnetic body (1400') housed in the movable bracket (1300'''). The inductance (L) value of the inductor part changes according to the displacement of the magnetic body (1400'). Therefore, in this case, the total capacitance value of the capacitor part (not shown) and the inductance (L) value of the inductor part change together, and the resonance frequency of the resonance circuit can be varied. In the contact state (c), the total capacitance value and the inductance value change together, but the change in the capacitance value may be greater than the change in the inductance value. In this case, the change in the capacitance value may have a dominant effect on the change in the LC value.

[0460] In the pressure state (P), a signal from the stylus pen is received by the touch input device, and it can be recognized that the stylus pen is in contact with the touch input device in a compressed state. For example, if the magnitude of the external force applied to the core body (1020) is greater than the elastic force that pushes the second moving member (1370') outward by the compressed elastic body (1700), it can be recognized as the pressure state (P).

[0461] Specifically, in the stylus pen illustrated in FIG. 39a (b) and FIG. 39b (b), in the pressure state (P), an external force greater than in the contact state (c) is applied to one end of the core body (1020). In the pressure state (P), even after the contact between the first electrode pattern (1390') and the second electrode pattern (1690') is released, the elastic member (1800) is further compressed by the external force applied to one end of the core body (1020), and the moving bracket (1300', 1300'') can move inwardly in the housing (1010) due to the deformation of the compressed elastic member (1800). When the moving bracket (1300', 1300'') moves in the pressure state (P), displacement of the magnetic body (1400, 1400') housed in the moving bracket (1300', 1300'') occurs, and since the magnetic body (1400, 1400') and the inductor part move away, the inductance (L) value gradually decreases. In this case, since the contact between the first electrode pattern (1390') and the second electrode pattern (1690') is released, the capacitance value is constant, but since the inductance value changes, the resonance frequency of the resonance circuit can be varied. Therefore, in this case, the change in the inductance value can have a dominant effect on the change in the LC value.

[0462] In addition, in the stylus pen illustrated in (b) of FIG. 39c, an external force greater than that in the contact state (c) is applied to one end of the core body (1020) in the pressure state (P). In the pressure state (P), even after the contact between the first electrode pattern (1390') and the second electrode pattern (1690') is released, the elastic member (1800') is further compressed by the external force applied to one end of the core body (1020), and the moving bracket (1300''') can move inwardly in the housing (1010) due to the deformation of the compressed elastic member (1800'). When the moving bracket (1300''') moves in the pressure state (P), displacement of the magnetic body (1400') housed in the moving bracket (1300''') occurs, and since the magnetic body (1400') and the inductor part move away, the inductance (L) value gradually decreases. In this case, since the contact between the first electrode pattern (1390') and the second electrode pattern (1690') is released, the capacitance value is constant, but since the inductance value changes, the resonance frequency of the resonance circuit can be varied. Therefore, in this case, the change in the inductance value can have a dominant effect on the change in the LC value.

[0463] A pen signal emitted from a stylus pen according to one embodiment of the present invention is based on the resonant frequency of a resonant circuit. According to one embodiment of the present invention, when the contact between the first electrode pattern (1390') and the second electrode pattern (1690') changes due to an external force applied to one end of the core body (1020), the capacitance (C) value of the resonant circuit changes, and thus the LC value may change. Additionally, according to one embodiment of the present invention, when displacement of the magnetic body (1400, 1400') housed in the movable bracket (1300', 1300'') occurs due to an external force applied to one end of the core body (1020), the inductance (L) value of the resonant circuit changes, and thus the LC value may change.

[0464] According to one embodiment of the present invention, the first detector (D1), discussed with reference to FIGS. 38a and FIG. 38b, may include an inductor, and the second detector (D2) may include a capacitor. Specifically, the first detector (D1) may include a magnetic body (1400) and a ferrite core (1210) for distinguishing a pressure state and / or detecting pressure, and the second detector (D2) may include a first electrode pattern (1390') and a second electrode pattern (1690') for distinguishing a contact state, and an elastic member (1800) for detecting or controlling pressure.

[0465] A sixth sealing member (2000f) according to one embodiment of the present invention is disposed between a first detection unit (D1) and a second detection unit (D2), and can separate a first space in which a component included in the first detection unit (D1) is located and a second space in which a component included in the second detection unit (D2) is located from each other.

[0466] Specifically, with reference to FIGS. 38a and 38b, since a magnetic body (1400, 1400') housed in a moving bracket (1300', 1300'') is located in the first space associated with the first detector (D1), a change in the LC value may occur due to a change in the inductance (L) value according to the displacement of the magnetic body (1400, 1400') in the first space. Since a first electrode pattern (1390') and a second electrode pattern (1690') are located in the second space associated with the second detector (D2), a change in the LC value may occur due to a change in the capacitance (C) value according to whether the first electrode pattern (1390') and the second electrode pattern (1690') are in contact in the second space. In addition, since an elastic member (1800) is located in the second space associated with the second detection unit (D2), a change in the LC value may occur due to a change in the inductance (L) value caused by the displacement of the elastic member (1800) due to an external force applied through the core (1020).

[0467] Additionally, referring to FIG. 38c, since a magnetic body (1400') housed in a moving bracket (1300''') is located in the first space associated with the first detection unit (D1), a change in the LC value may occur due to a change in the inductance (L) value caused by the displacement of the magnetic body (1400') in the first space. Additionally, since an elastic member (1800') is also located in the first space associated with the first detection unit (D1), a change in the LC value may occur due to a change in the inductance (L) value caused by the displacement of the elastic member (1800) due to an external force applied through the core body (1020). Since the first electrode pattern (1390') and the second electrode pattern (1690') are located in the second space associated with the second detection unit (D2), a change in the LC value may occur due to a change in the capacitance (C) value depending on whether the first electrode pattern (1390') and the second electrode pattern (1690') come into contact in the second space.

[0468] Accordingly, according to embodiments of the present invention described with reference to FIGS. 38a to 38c, the first space associated with the first detection unit (D1) and the second space associated with the second detection unit (D2) can be separated by the sixth sealing member (2000f), and the hover, contact, pressure, and button states can be distinguished by a change in the LC value by at least one of the components included in the first detection unit (D1) and the second detection unit (D2).

[0469] Using a stylus pen according to an embodiment of the present invention has the advantage that a reference pressure distinguishing between hover and contact can be clearly set, thereby making the distinction between hover and contact clear. Additionally, using a stylus pen according to an embodiment of the present invention has the advantage that moisture entering the second detection unit (D2), where the first electrode pattern (1390') and the second electrode pattern (1690') are located, through the second moisture inflow path (P2') is prevented by the sixth sealing member (2000f), while at the same time, at least one of the hover, contact, pressure, and button states can be distinguished.

[0470] In addition, using a stylus pen according to an embodiment of the present invention allows the space associated with the first detection unit (D1) and the space associated with the second detection unit (D2) to be separated from each other, thereby providing the advantage of being able to independently operate components and / or circuit configurations necessary for sensing such as hover, contact, and pressure without affecting each other's spaces. Accordingly, using a stylus pen according to an embodiment of the present invention prevents moisture from entering through the second moisture inflow path (P2') through one or more sealing members, or prevents interference with the electrical connection between the electrode pattern (1390') formed on the second moving member (1370') and the electrode pattern (1690') formed on the fixed bracket (1600'). In addition, since the components required for sensing such as hover, contact, and pressure are not located in a single space, and at least one of the components required for sensing such as hover, contact, and pressure can be separated from one another by the sixth sealing member (2000f), the circuit and mechanism configuration can be operated independently, thereby increasing the degree of design freedom.

[0472] Reduction of movement deviation in the internal configuration of a stylus pen including a sixth sealing member

[0473] FIG. 41a is a drawing showing the internal components and cross-sectional view of the stylus pen shown in FIG. 3 and 4. FIG. 41b is a drawing for explaining the movement deviation of the movable bracket (1300) of the stylus pen shown in FIG. 3 and 4. FIG. 41c is a drawing showing the internal components and cross-sectional view of the stylus pen including the sixth sealing member shown in FIG. 38a to 38c.

[0474] Specifically, FIG. 41a(a) illustrates some of the internal components of the stylus pen discussed with reference to FIG. 3 through FIG. 14, and FIG. 41a(b) illustrates a cross-sectional view taken in a plane perpendicular to the longitudinal direction of the stylus pen illustrated in FIG. 41a(a). Referring to FIG. 41a(a) and (b), a core body (1020) and a magnetic body (1400) may be housed inside the movable bracket (1300). Inside the house, the magnetic body (1400) may be positioned to surround the core body (1020). The magnetic body (1400) housed inside the movable bracket (1300) contains a magnetic material and moves together with the movable bracket (1300) in synchronization with the movement of the core body (1020). At least a portion of the extension of the movable bracket (1300) may be located on the inner side of the elastic body (1700).

[0475] Meanwhile, referring to FIG. 41a (a), FIG. 41a (b) and FIG. 11a, the movable bracket (1300) may include an electrode pattern (1390), and the electrode pattern (1390) may be formed on the outer surface of the movable bracket (1300). The electrode pattern (1390) may be formed on a protrusion of the movable bracket (1300) and may be in contact with the electrode pattern (1690) formed on the outer surface of the fixed bracket (1600). Accordingly, in order to form contact between the electrode pattern (1390) of the movable bracket (1300) and the electrode pattern (1690) of the fixed bracket (1600), the protrusion on which the electrode pattern (1390) of the movable bracket (1300) is formed may be placed between the groove on which the electrode pattern (1690) of the fixed bracket (1600) is formed.

[0476] Meanwhile, since the protrusion of the movable bracket (1300) is positioned between the groove of the fixed bracket (1600), a gap may occur between the protrusion and the groove. Referring to FIG. 41b, the deviation in movement of the movable bracket (1300) due to the gap between the protrusion of the movable bracket (1300) of the stylus pen and the groove of the fixed bracket (1600) is illustrated. Specifically, FIG. 41b(a) illustrates a cross-sectional view of the stylus pen described with reference to FIG. 3 to FIG. 14, cut in the xy plane. Here, the y direction is the length direction of the stylus pen, and the x direction is the width direction of the stylus pen. Referring to (a) of FIG. 41b, due to the gap between the protrusion of the moving bracket (1300) of the stylus pen according to one embodiment and the groove of the fixed bracket (1600), a deviation in the tilt movement of the moving bracket (1300) in the xy plane may occur.

[0477] Meanwhile, FIG. 41b(b) illustrates a cross-sectional view taken in the xz plane when the stylus pen described with reference to FIG. 3 to FIG. 14 is viewed in the longitudinal direction (y-axis direction). Referring to FIG. 41b(b), due to the gap between the protrusion of the movable bracket (1300) of the stylus pen according to one embodiment and the groove of the fixed bracket (1600), an azimuth movement deviation of the movable bracket (1300) may occur in the xz plane. If a movement deviation of the movable bracket (1300) occurs, there is a risk that a movement deviation may also occur in the magnetic body (1400) which is placed inside the movable bracket (1300) and whose movement is linked. If a relative displacement occurs with respect to the inductor part located inside the stylus pen due to the movement of the magnetic body (1400), the inductance (L) value of the inductor part may change. Therefore, there is a possibility that an error in pressure sensing may occur due to the movement deviation of the magnetic material (1400).

[0478] Meanwhile, FIG. 41c is a drawing illustrating the internal components and cross-sectional view of a stylus pen including the sixth sealing member illustrated in FIG. 38a to FIG. 38c. Specifically, FIG. 41c (a) illustrates some of the internal components of the stylus pen described with reference to FIG. 38a and a cross-sectional view thereof, and FIG. 41c (b) illustrates some of the internal components of the stylus pen described with reference to FIG. 38b and FIG. 38c and a cross-sectional view thereof.

[0479] As described with reference to FIGS. 38a to 38c, in a stylus pen including a sixth sealing member, the first electrode pattern (1390') that contacts the second electrode pattern (1690') of the fixed bracket (1600') is formed on the outer surface of the second movable member (1370') rather than the movable bracket (1300', 1300'', 1300'''). Accordingly, there is no need to form a protrusion on the movable bracket (1300', 1300'', 1300'''), and the fixed bracket (1600') can be formed in a structure that completely covers the outer surface of the movable bracket (1300', 1300'', 1300''').

[0480] Therefore, unlike the internal configuration of the stylus pen shown in FIG. 41a to FIG. 41b, no gap occurs between the movable bracket (1300', 1300'', 1300''') and the fixed bracket (1600') of the stylus pen shown in FIG. 41c (a) and FIG. 41c (b), so the deviation of movement of the movable bracket (1300', 1300'', 1300''') can be reduced. When the movement deviation of the moving bracket (1300', 1300'', 1300''') is reduced, the movement deviation of the magnetic body (1400, 1400') housed inside the moving bracket (1300', 1300''', 1300''') and whose movement is linked is also reduced, so the error in the change amount of the inductance (L) value of the inductor part due to the movement deviation of the magnetic body (1400, 1400') can be reduced. Accordingly, a stylus pen including a sixth sealing member according to one embodiment of the present invention can be arranged in a closed structure in which the fixed bracket (1600') completely surrounds the outer surface of the movable bracket (1300', 1300'', 1300'''), and the movement deviation of the movable bracket (1300', 1300''') and the magnetic body (1400, 1400') is reduced, thereby having the effect of reducing the error in pressure detection caused by the movement deviation.
