  Hereinafter, a touch pen according to an embodiment of the present invention will be described with reference to the drawings.

[First embodiment]
FIG. 1 is a view showing the appearance of a touch pen 10 according to a first embodiment of the present invention. The touch pen 10 according to the first embodiment is used to operate an electronic device provided with a touch panel such as an electronic blackboard and a tablet terminal, and more specifically, the touch input designates an arbitrary coordinate (point) on the touch panel It is used when writing, lines, characters, etc.

  Referring to FIG. 1, touch pen 10 includes a housing 12, which is formed of a nonconductive resin. However, the housing 12 may be formed of a conductive resin, a nonconductive resin on which conductive plating has been applied, or a metal (for example, aluminum). Also, the touch pen 10 includes a pen tip 14, and a pen tip cover 16 covering a part of the pen tip 14 is joined to the housing 12. The pen point cover 16 is also formed of a nonconductive resin. Further, a button 18 is provided on the surface of the housing 12. Furthermore, the touch pen 10 includes a lock member 20, and is attached to an end of the housing 12 opposite to the end to which the pen tip cover 16 is joined.

  The housing 12 is formed in a cylindrical shape, and a holder (holding portion) 30 described later is connected to an end on the side to be joined to the pen tip cover 16, and the pen tip 14 is attached to the holder 30. The pen point 14 is formed of a conductive resin. In the first embodiment, the pen point 14 is formed of conductive polyacetal. The polyacetal having conductivity is a relatively hard resin. Also, both ends of the pen point 14 are tapered toward the end as compared to the central part excluding them. A button 18 is provided on the side of the housing 12. In this embodiment, the case where one button 18 is provided will be described, but two or more buttons 18 may be provided.

  Generally, the pen tip 14 is formed of a soft material so as not to damage the touch panel, but in the case of the touch pen 10 used for a capacitive touch panel, the pen tip 14 is a resin having conductivity. The pen tip 14 is therefore made of a relatively hard material.

  In addition, the housing 12 accommodates one electronic substrate 32 extending in the longitudinal direction of the housing 12 (see FIG. 2C). Although the illustration is omitted, the housing 12 is constituted by two members, and the two members are fixed by sandwiching the electronic board 32 and fixed by attaching the pen point cover 16 and the lock member 20.

  Note that power is supplied to each circuit component mounted on the electronic substrate 32 from a battery provided in the housing 12 in a replaceable manner.

  The pen tip cover 16 is formed in a frusto-conical shape whose diameter is gradually reduced toward the tip (opposite to the housing 12), and an opening 160 for passing the pen tip 14 through the tip surface (upper surface of the truncated cone). Is provided. In addition, the pen point cover 16 is provided with an opening 162 at the bottom of the truncated cone, and a part of the housing 12, a part of the pen tip 14 and the holder 30 are accommodated from the opening 162 and joined to the housing 12 Yes). However, instead of being screwed into the housing 12, the nib cover 16 may be bonded or fixed with a screw structure.

  The button 18 is assigned a predetermined function. For example, a function to turn on / off the power of the touch pen 10 and a function to select a mode (pen or eraser mode) or a menu (type of line, thickness, color, etc.) are applicable. For example, when the button 18 is pressed and held, power is turned on / off. Also, when the button 18 is pressed (not long press) while the power of the touch pen 10 is turned on, the mode or menu is sequentially changed and selected.

  FIG. 2A is an enlarged view of a portion including the pen tip 14 of the touch pen 10 according to the first embodiment, and FIG. 2B shows a state in which the pen tip cover 16 is removed in FIG. FIG. 2C is a cross-sectional view of a portion including the pen tip 14 of the touch pen 10 of FIG. 2A.

  With reference to FIGS. 2A to 2C, the holder 30 has a sandwiching portion 30a constituted by a portion in which the end portion on the side holding the pen tip 14 is equally divided into two. The pen tip 14 is held (held) by the holding portion 30a. In the first embodiment, the holder 30 is formed of a nonconductive resin (hard resin such as polyethylene, polystyrene, polycarbonate, or ABS), but a conductive resin (hard resin such as conductive polyacetal or conductive polyethylene) And the like.

  The holding portion 30a is divided into two parts except the surface on the side where the hollow cylinder is connected to the housing 12 (the bottom surface of the cylinder), and the height direction of the column on the side surface of the cylinder (axial direction of the pen point 14 A hole 300 is formed penetrating in the direction orthogonal to. In addition, a hole 302 is formed at the center of the end (end face) on the side of holding the pen tip 14 by the two separated parts of the sandwiching part 30a. The diameter of the hole 302 is set smaller than the diameter of the pen tip 14 in the state where the pen tip 14 is not held. Therefore, when the pen tip 14 is attached to the holder 30, the two separated portions of the holding portion 30a are bent outward (in the direction in which the two holding portions 30a are separated). For this reason, a restoring force is generated in each of the two separated portions of the holding portion 30a, and the pen tip 14 is held (held) by the restoring force. As described above, since only the pen tip 14 is held by the bending of the part separated into two of the holding portion 30a, even a relatively hard pen point 14 can be easily replaced.

  In addition, the holder 30 includes a linear bar member 30b extending on the opposite side to the end portion on the side holding the pen tip 14, and the bar member 30b is connected to the sandwiching portion 30a. Moreover, the disk member 30c is provided in the rod member 30b at a predetermined distance from the sandwiching portion 30a. The holder 30 is connected to the housing 12 such that the disc member 30 c is located in the space provided at the end of the housing 12. Since the disk member 30 c is provided with a gap with the housing 12, the disk member 30 c is displaceable in the axial direction of the touch pen 10 (pen tip 14). Therefore, the pen tip 14 is displaced in the axial direction of the touch pen 10 together with the holder 30 in a range in which the disc member 30 c can be displaced.

  Although not shown, the controller for controlling the touch pen 10, an interface for inputting the on / off signal of the button 18 to the controller, memory (ROM and RAM), Bluetooth (registered trademark), although not shown. Alternatively, a communication circuit of a predetermined communication method such as Wi-Fi (registered trademark), a power supply line, a signal line, and the like are provided.

  The fact that the button 18 has been operated (pressed) is notified to the computer controlling the electronic blackboard or the like through the communication circuit and the antenna. Therefore, the computer detects that the touch panel 10 is touched by the touch pen 10. However, the communication circuit may be connected to a processor mounted on the electronic substrate 32 so as to be able to transmit and receive data without being mounted on the electronic substrate 32.

  Also, the pressure sensor 34 is attached (fixed) to the electronic substrate 32. The pressure sensor 34 has a detection surface larger (wider) than the diameter of the pen tip 14 and is formed in an L-shaped cross section. The detection surface (detection portion) of the pressure sensor 34 corresponds to the portion of the L-shaped vertically elongated rod in the cross section, and is disposed perpendicularly to the direction in which the rod member 30 b of the holder 30 is displaced. Therefore, when the pen tip 14 and the holder 30 are displaced to the housing 12 side, the rod member 30 b of the holder 30 hits the detection portion of the pressure sensor 34. Therefore, the resistance value changes in the detection unit of the pressure sensor 34. As a result, it is detected that the pen tip 14 and the holder 30 are displaced to the housing 12 side, that is, that the touch pen 10 is touching the touch panel or the like. The detection result is notified to the computer controlling the electronic blackboard or the like through the communication circuit and the antenna, as in the case where the button 18 is pressed.

  In the touch pen 10 having such a configuration, since the pen tip 14 has conductivity, when the pen tip 14 of the touch pen 10 contacts the capacitive touch panel, the inside of the touch panel is touched at the portion where the pen tip 14 contacts. The capacitance between the electrodes of is changed, whereby it is detected that the part is touched.

  According to the first embodiment, since the pen tip 14 is simply held by the bending of the part separated into two of the holding portion 30a of the holder 30, even the pen tip 14 formed of a relatively hard material is easily It can be exchanged.

  In the touch pen 10 of the first embodiment, an electronic pen provided with the button 18, the electronic substrate 32, and the pressure sensor 34 is configured, but a stylus pen having no electrical configuration may be configured.

  Further, in the first embodiment, the holder 30 is connected to the housing 12 so as to be displaceable in the axial direction of the pen tip 14, but it is not necessary to be limited to this. For example, the holder 30 may be pressed into or bonded to the housing 12.

  Furthermore, in the first embodiment, the two holding portions 30a are provided separately, but three or more holding portions 30a may be provided. However, it is necessary to hold the pen tip 14 with equal resilience by each separated part.

  Furthermore, in the first embodiment, the pen tip 14 is formed of conductive polyacetal, but in the case of the touch pen 10 used for an infrared touch panel or resistive touch panel, the pen tip 14 has no conductivity. It is formed of high molecular weight polyethylene. Even when the pen tip 14 is formed of ultrahigh molecular weight polyethylene having no conductivity, the user can easily use the pen tip 14 by configuring the touch pen 10 as described in the first embodiment described above. It can be exchanged.

Second Embodiment
The touch pen 10 of the second embodiment is the same except that the holder 30 of the touch pen 10 of the first embodiment is changed to another holder 40, so different contents will be described.

  FIG. 3A is an enlarged view of a portion including the pen tip 14 of the touch pen 10 according to the second embodiment, showing a state in which the pen tip cover 16 has been removed, and FIG. FIG. 2 is a cross-sectional view of a portion including the pen tip 14 of the touch pen 10 of the embodiment.

  In the second embodiment, the holder 40 includes a cylindrical portion 40a, and a cylindrical soft material 42 is accommodated in the cylindrical portion 40a. As the soft material 42, a resin (elastic member) such as urethane or rubber can be used. The soft material 42 has a hole (insertion hole) 42a for holding the pen tip 14 at the center of a cylinder. The holes 42 a are set to diameters smaller than the diameters of both ends of the pen tip 14 and the neck 140 in a state where the pen tip 14 is not held. The pen point 14 is pressed into the hole 42 a of the soft material 42. Since the end of the pen point 14 is thinner than the central portion, it is easier to press the pen point 14 into the hole 42 a of the soft material 42 than when the end is not narrowed. The pen point 14 inserted into the hole 42 a of the soft material 42 is fixed by the frictional force with the soft material 42. Further, on the side surface of the soft material 42, a plurality of protrusions 42b are formed. In the second embodiment, the two protrusions 42b are formed at positions shifted by 180 ° on the outer periphery of the side surface.

  The end face of the cylindrical portion 40a on the pen tip 14 side is opened, and the end face on the opposite side is closed. A plurality of holes (engagement holes) 400 for engaging the plurality of protrusions 42 b are formed on the side surface of the cylindrical portion 40 a. In the second embodiment, two holes 400 are formed at positions corresponding to the protrusions 42 b and at positions opposed to each other. The engagement of the projection 42b with the hole 400 prevents the soft material 42 from being detached from the cylindrical portion 40a when replacing the pen tip 14 or using the touch pen 10.

  Although the two holes 400 may be formed at a position shifted from the facing position, it is necessary to prevent the two holes 400 from coming too close. This is because when the two holes 400 are too close to each other, the anti-disengagement effect is almost the same as when one hole 400 is formed. However, when the positions of the two holes 400 are formed at a position shifted from the facing position, the positions of the two projections 42 b provided on the side surface of the soft material 42 are also changed accordingly.

  In addition, the holder 40 includes a linear bar member 40 b extending on the opposite side to the end portion on the side holding the pen tip 14, and the bar member 40 b is connected to the cylindrical portion 40 a. Further, a disk member 40c is provided on the rod member 40b at a predetermined distance from the cylindrical portion 40a. The holder 40 is connected to the housing 12 such that the disc member 40 c is located in the space provided at the end of the housing 12. Since the disk member 40 c is provided with a gap with the housing 12, the disk member 40 c can be displaced in the axial direction of the touch pen 10 (pen tip 14) in the above-mentioned space. Therefore, the pen tip 14 is displaced in the axial direction of the touch pen 10 together with the holder 40 in a range in which the disc member 40 c can be displaced.

  When the pen tip 14 and the rod member 40b of the holder 40 are displaced toward the housing 12 when the touch pen 10 is used, the point that the rod member 40b of the holder 40 hits the pressure sensor 34 is the first embodiment. Is the same as

  According to the second embodiment, since the pen point 14 is only pressed into the hole 42a of the soft material 42, the pen point 14 can be easily replaced as in the first embodiment.

  In the second embodiment, the hole 400 is formed on the side surface of the cylindrical portion 40a and the protrusion 42b is formed on the side surface of the soft material 42. However, in the case of bonding the soft material 42 to the cylindrical portion 40a, The hole 400 and the protrusion 42b may not be formed.

Third Embodiment
The touch pen 10 of the third embodiment is the same as that of the first embodiment except that the shapes of the pen tip 14 and the holder 30 are different, so only different contents will be described.

  FIG. 4A is an enlarged view of a portion including the pen tip 14 of the touch pen 10 according to the third embodiment, showing a state in which the pen tip cover 16 has been removed, and FIG. FIG. 2 is a cross-sectional view of a portion including the pen tip 14 of the touch pen 10 of the embodiment.

  In the third embodiment, the holding portion 30 a of the holder 30 has a claw 310 projecting toward the pen tip 14. In the pen point 14, a constriction 140 is provided at a portion corresponding to the claw 310. Therefore, the hole 302 formed by the sandwiching portion 30 a is considerably smaller than the diameter of the portion of the pen tip 14 where the neck 140 is provided and the portion excluding the both end portions of the pen tip 14. For this reason, when the claw 310 is engaged with the constriction 140 of the pen tip 14, the pen tip 14 can be made difficult to separate from the holder 30 compared to the touch pen 10 of the first embodiment.

  Also in the third embodiment, the same effects as in the first embodiment can be obtained.

  Further, in the third embodiment, when the pen tip 14 is attached to the holder 30, the claw 310 is locked to the neck 140 after passing through a portion thicker than the neck 140 of the pen tip 14, the deflection of the holding portion 30a The friction force generated with the pen tip 14 changes with this. Therefore, the user can know that the pen tip 14 is properly inserted to the position by the touch of the hand.

Fourth Embodiment
The touch pen 10 according to the fourth embodiment is the same as the first embodiment except that the housing 12 having conductivity is used and the housing 12 and the pen tip 14 are electrically connected, so only different contents will be described. Do.

  FIG. 5A is an enlarged view of a part including the pen tip 14 of the touch pen 10 according to the fourth embodiment, showing a state in which the pen tip cover 16 has been removed, and FIG. FIG. 2 is a cross-sectional view of a portion including the pen tip 14 of the touch pen 10 of the embodiment.

  In the touch pen 10 of the fourth embodiment, a conductive member 50 which is partially disposed between the pen tip 14 and the holder 30 and extends to the inside of the housing 12 is provided. The conductive member 50 is formed by appropriately bending a plate of conductive metal (such as aluminum or copper) extending in a band shape. Although not shown, the conductive member 50 is in contact with the inner side surface of the housing 12 inside the housing 12. For example, the conductive member 50 is bonded to the inner surface of the housing 12 using a conductive adhesive. Therefore, the housing 12 and the pen tip 14 are electrically connected (conductive). The conductive member 50 also functions as a leaf spring.

  In the touch pen 10 having such a configuration, the pen tip 14 is electrically connected (conductive) to the conductive housing 12 via the conductive member 50. In addition, the housing 12 can be considered to be grounded since the housing 12 is in contact with the user's finger gripping (using) the touch pen 10. Therefore, sufficient capacitance can be secured. Therefore, when the pen tip 14 of the touch pen 10 contacts the capacitive touch panel, the capacitance between the electrodes inside the touch panel largely changes at the portion where the pen tip 14 contacts, which causes the portion , It is detected that the touch has been made.

  When the touch pen 10 according to the fourth embodiment performs touch panel, the pen tip 14 and the holder 30 are displaced toward the housing 12 side. Therefore, the conductive member 50 is bent. Therefore, a restoring force is exerted on the conductive member (leaf spring) 50, and the pen tip 14 and the holder 30 are biased (pushed back) to the side opposite to the housing 12 side. That is, although the pen tip 14 is displaced toward the housing 12 by the writing pressure of the user, the pen tip 14 is biased in the opposite direction by the conductive member 50, so that touch input can be performed with an appropriate writing pressure. Therefore, when the user uses the touch pen 10 to write characters and the like, the user can feel a sense of incongruity and provide smooth writing.

  According to the fourth embodiment, the effects of the first embodiment can be obtained, and even with a relatively large touch panel such as a touch panel provided on the electronic blackboard, the change in capacitance is large. It can be detected correctly.

  Further, according to the fourth embodiment, when writing characters or the like using the touch pen 10, when the pen tip 14 and the holder 30 are displaced to the housing 12 side, they are pushed back by the conductive member (leaf spring) 50. Therefore, it is possible to provide a smooth writing taste.

  In the fourth embodiment, the conductive member 50 which also functions as a leaf spring is provided. However, the present invention is not limited to this. Instead of the conductive member 50, a rubber or compression spring may be disposed between the pen tip 14 and the holder 30.

  The modification of the fourth embodiment can also be applied to the touch pens 10 of the second and third embodiments. However, in the case of applying to the touch pen 10 of the second embodiment, it is necessary to form a hole for bringing the conductive member 50 into contact with the pen tip 14 on the side surface of the cylindrical portion 40 a.

Fifth Embodiment
The touch pen 10 of the fifth embodiment is the same as the first embodiment except that the internal structure of the pen tip cover 16 is different, so only different contents will be described.

  In the touch pen 10 of the fifth embodiment, a cylindrical support portion 60 connected to the opening 160 of the pen tip cover 16 is provided. The pen tip 14 is held by the holder 30 through the hole formed by the opening 160 and the support 60.

  For example, when the supporting portion 60 is not provided, when a strong impact is applied to the tip of the pen tip 14 of the touch pen 10, the pen tip is at or near the midpoint between the tip of the pen tip cover 16 and the holder 30. The 14 may buckle and the pen tip 14 may be broken. In addition, when the touch pen 10 is used, the pen tip 14 may be wobbled and touch input may be difficult. In this respect, in the touch pen 10 according to the sixth embodiment, the pen tip 14 is supported by the support portion 60, so that the above-described inconvenience can be avoided and the pen tip 14 can be protected.

  According to the fifth embodiment, since the cylindrical support portion 60 connected to the opening 160 of the pen tip cover 16 is provided, in addition to the effects of the first embodiment, the pen tip 14 is protected and the pen tip 14 is Wobble can be prevented.

  FIG. 7A is an enlarged view of a portion including the pen tip 14 of the touch pen 10 according to the sixth embodiment, and FIG. 7B is a view of the pen tip cover 16 as viewed from the opening 162 side. FIG. 7C is a cross-sectional view of a portion including the pen tip 14 of the touch pen 10 of FIG. 7A.

  In the touch pen 10 of the sixth embodiment, the support portion 70 connected to the opening 160 is formed of a plurality of plate members 70 a inside the pen tip cover 16. Each of the plurality of (six in the sixth embodiment) plate members 70a is formed in a triangular shape. However, the side connected to the pen point cover 16 is curved along the shape of the pen point cover 16. The plurality of plate members 70 a are disposed at predetermined angles (60 ° in the sixth embodiment) around the axis of the touch pen 10. A hole similar to the cylindrical support portion 60 shown in the fifth embodiment is formed by a plurality of sides opposed to the side connected to the pen point cover 16 among the plate members 70a. That is, the support 70 forms a hole connected to the opening 160. Therefore, also in the sixth embodiment, the pen point 14 is held by the holder 30 through the cylindrical hole formed by the opening 160 and the support 70.

  The number of the plate members 70 a and the predetermined angle to be disposed can be appropriately changed as long as the holes capable of supporting the pen tip 14 can be formed.

  According to the sixth embodiment, since the cylindrical hole connected to the opening 160 of the pen tip cover 16 is provided while achieving the effects of the first embodiment, the pen tip 14 is protected as in the fifth embodiment. At the same time, wobble of the pen tip 14 can be prevented.
