Japanese Patent Laid-Open No. 10-171580 Japanese Patent Laid-Open No. 10-161895

  The conventional capacitance type input pen is configured as described above, and it is necessary to operate the hard pen tip 30A by pressing it strongly against the screen 2 of the portable music apparatus 1, so that excessive press contact of the pen tip 30A is required. Therefore, there is a problem that the screen of the portable music device 1 may be damaged. In addition, a user with a hand or arm disorder may operate the button 2 of the screen 2 or the soft keyboard 3 with the capacitive input pen in his mouth. In this case, the pen tip 30A is strongly pressed. There is a problem that the operation cannot be performed and the operation is hindered.

  The present invention has been made in view of the above, and an object of the present invention is to provide a capacitive input pen that can be smoothly operated without strongly bringing the pen tip into contact with a screen, a keyboard, or the like.

  In the present invention, in order to solve the above problems, a pen body used by a user is provided, and a conductive pen tip is supported at the tip of the pen body, and a plurality of pen tips are provided. It is characterized in that it is formed into a brush shape with conductive fibers.

The pen body can be a conductive hollow shaft, and a capacitor can be built in the hollow shaft.
Also, the nib can be a flat brush shape, a corner brush shape, an attached brush shape, a face brush shape, a fan shape, or a mop shape.

  Here, the pen body in the claims is preferably a hollow shaft, and in this case, a plurality of flow ports can be provided in the hollow shaft to allow air to flow outside. Capacitors include a single type, a laminated type, a wound type, and an electrolytic capacitor, but are not particularly limited as long as the voltage holding function is not hindered. Furthermore, the capacitive input pen according to the present invention is mainly a capacitive portable music device, but is not limited to this, and is suitable for a capacitive portable game device or the like. Can also be used.

  According to the present invention, if the pen tip is brought into contact with the screen or keyboard of a capacitance-type portable electronic device or slid in a contact state, the pen tip is bent and its contact area is changed. A predetermined input operation can be performed smoothly.

  According to the present invention, there is an effect that smooth operation can be performed without bringing the pen tip into strong contact with the screen or keyboard of a portable electronic device.

In addition, if the pen body is made of a conductive hollow shaft, electrical conductivity is generated from the pen body to the pen tip, and the electrostatic capacity of the human body can be transmitted to the pen tip. It can be expected that a stable and good operation is maintained.
Also, if the nib is a flat brush shape, corner brush shape, attached brush shape, face brush shape, fan shape, or mop shape, the type of nib can be changed as necessary, so the shape of the nib The convenience of diversification and handling can be improved.

  Hereinafter, a preferred embodiment of a capacitive input pen according to the present invention will be described with reference to the drawings. The capacitive input pen according to the present embodiment has a capacitance as shown in FIG. 1 and FIG. A conductive pen main body 10 used for a portable music device 1 is provided, and an image of the screen 2 of the portable music device 1 and a button 4 of the soft keyboard 3 are brought into contact with the tip 15 of the pen main body 10. A conductive nib 30 is inserted, and the nib 30 is easily formed into a flexible brush shape whose contact area changes.

  The pen body 10 includes a first hollow shaft 11 in which a pen tip 30 is inserted and attached to a tip end portion 15, and a second hollow shaft that is detachably screwed into an open end portion of the first hollow shaft 11. 12 is formed in a hollow shaft having a capacity of 12 and is held by a user who is a capacitance body or used in the mouth. These first and second hollow shafts 11 and 12 are formed using a conductive material, specifically, a molding material or a metal material containing a resin and a conductive filler, and ensure capacitance. Capacitor 13 is built in and conducted.

  The first hollow shaft 11 is formed in a cylindrical shape suitable for gripping the user, the tip portion 15 is formed in a tapered shape with a reduced diameter, and the second hollow portion is formed on the outer peripheral surface of the opened end portion. A screw 16 for coupling with the shaft 12 is formed. The first hollow shaft 11 is formed with a plurality of ring-shaped holding ribs 17 for holding the pen tip 30 on the inner peripheral surface of the tip portion 15 so as to protrude radially inward, and on the peripheral wall near the tip portion 15. The circulation port 18 for circulating air between the outside and the outside is perforated.

  The second hollow shaft 12 is formed in a cylindrical shape with a thickness capable of accommodating the capacitor 13, and is detachably engaged with the screw 16 of the first hollow shaft 11 on the inner peripheral surface of the open end portion 15. A threaded groove 19 is formed in a threaded manner, and a conductive tail plug 20 having a substantially U-shaped cross section facing the capacitor 13 is detachably press-fitted into the open end portion. In the second hollow shaft 12, a slight gap is defined between the inner peripheral surface of the peripheral wall and the capacitor 13, and this gap circulates air in the axial direction of the pen body 10.

  On the inner peripheral surface of the peripheral wall of the second hollow shaft 12, a ring-shaped support rib 21 that prevents the accommodated capacitor 13 from dropping off is formed in a radially inward direction. A circulation port 18 for circulating air in the axial direction is drilled. In addition, a circulation port 18 through which air is circulated is formed in the peripheral wall near the end of the second hollow shaft 12.

  The capacitor 13 is inserted, for example, from the end of the second hollow shaft 12 from which the tail plug 20 is removed and supported by the support rib 21, and the lower terminal 14 penetrating through the hollow of the support rib 21 is bent and the first end is bent. While being in contact with the inner peripheral surface of the peripheral wall of one hollow shaft 11, the upper terminal 14 extends to the filament and opposes the opposing surface of the tail plug 20 so as to be able to contact and separate. The capacitor 13 having such a configuration exhibits a power storage function when the upper terminal 14 and the tail plug 20 that is selectively deeply press-fitted are brought into conductive contact.

  The pen tip 30 is formed into a corner-brush shape, an attached brush shape, or a face brush shape that can be bent easily by bundling a plurality of conductive fibers 31 having flexibility. The tip is made narrower than the fingertip so that it is easy. The conductive fiber 31 of the nib 30 is not particularly limited. For example, copper sulfide is applied to a metal wire, carbon fiber, a fiber in which micron-sized carbon black particles are kneaded, a metal-plated fiber, and a nylon fiber. Examples thereof include organic conductive fibers chemically bonded and fibers coated with a conductive polymer on the surface.

  In the above configuration, when the screen 2 or the soft keyboard 3 of the portable music device 1 is operated, the pen tip 30 of the capacitive input pen is brought into contact with the image of the screen 2 or the button 4 of the soft keyboard 3, What is necessary is just to make it contact and to slide up and down, right and left. Then, electrical conductivity is generated from the pen body 10 to the pen tip 30, the electrostatic capacity of the human body is supplied to the pen tip 30, and the pen tip 30 bends with contact to change / enlarge the contact area. The input operation can be reliably performed without stress.

  According to the above configuration, since the pen tip 30 bends to change the contact area, it is not necessary to operate the pen tip 30 by pressing it strongly against the screen 2 of the portable music apparatus 1 as in the prior art. Therefore, the possibility of damage to the screen 2 due to excessive pressure contact of the pen tip 30 can be effectively eliminated, and various gesture inputs can be performed. In addition, even when the capacitive input pen is held in the mouth and the screen 2 or the soft keyboard 3 is operated, the pressing force of the pen tip 30 can be reduced, so that operability and workability can be significantly improved. it can.

  Moreover, since the capacitor | condenser 13 holding a voltage is built in the pen main body 10, stable and reliable operation can be expected. Furthermore, since a plurality of flow ports 18 are drilled in the first and second hollow shafts 11 and 12 to allow air to flow outside, for example, when an infant accidentally swallows a capacitive input pen However, it does not interfere with breathing and can improve safety.

  Next, FIG. 2 shows a second embodiment of the present invention. In this case, the pen tip 30 is not shaped like a spindle having a tapered tip, but gradually bends outwardly toward the tip. The fan shape or mop shape is widened. The other parts are substantially the same as those in the above embodiment, and thus description thereof is omitted.

  In this embodiment, the same effect as that of the above embodiment can be expected. Moreover, since the pen tip 30 is fan-shaped or mop-shaped spreading outward, the contact area of the pen tip 30 with respect to the screen 2 can be further expanded. It is clear that the image on the screen 2 can be smoothly scrolled in a contact state.

  In the above-described embodiment, the pen body 10 is configured by the first and second hollow shafts 11 and 12 in order to ensure conductivity. However, the present invention is not limited to this. You may comprise by a hollow shaft. Moreover, you may detachably fit the cap with a clip which protects the pen tip 30 to the front-end | tip part 15 of the pen main body 10 of the said embodiment. In addition, the storage and connection of the capacitor 13 may be appropriately changed as necessary as long as the voltage can be maintained. Further, the pen tip 30 may be a flat brush shape or the like as long as the operability is not hindered.
