Description

  The present invention relates to a touch pen for electronic devices used as a pointing device for touch panels of various electronic devices such as portable information terminals, mobile phones, computer peripheral devices, and tablets.

  In particular, the shaft portion in the longitudinal direction of the touch pen for electronic devices is relatively slidable between the front barrel having a tip portion that cooperates with various types of position detection sensors provided on the touch panel, and the front barrel. This is composed of a rear barrel.

  In addition, the clip used when the electronic device touch pen is held in a pocket or the like is attached to the rear shaft portion in a removable form.

  By adopting such a configuration, the touch pen for electronic equipment of the present invention achieves selective compaction in the longitudinal direction of the entire touch pen, and improves the convenience of the user when using the touch pen and when storing it.

  Furthermore, an elastic member is provided to ensure the contact state between the front shaft cylinder and the rear shaft cylinder during the slide operation, and the change in the contact state over time, that is, the so-called “sagging of the slide operation contact portion” is provided. The phenomenon is prevented.

  In this specification, the side of the sensor cooperating unit that cooperates with the position detection sensor provided on the touch panel is referred to as “front” and “front”, and the side opposite to the longitudinal direction of the touch pen for electronic devices is referred to as “rear”. ".

  A conventional touch pen for electronic equipment used as a pointing device for a touch panel has a unique length like an ordinary mechanical pencil or ballpoint pen and cannot be shortened when stored (see Patent Document 1). .

  Further, in the case of an electronic device touch pen with a clip attached to the rear end side, the user cannot easily remove the clip as needed.

Respectively.

  As described above, the illustrated electronic device touch pen includes the sensor cooperation unit 1, the front shaft operation unit 2, the rear shaft operation unit 3, and the clip mechanism unit 4.

Its basic features are
(21) The front shaft action part 2 and the rear shaft action part 3 are moved relative to each other in the front-rear direction, for example, the rear shaft cylinder 3a in which the front part is accommodated in the front shaft cylinder 2a is pulled out rearward, and then It is possible to easily set the selective expansion / contraction state of the entire length of the touch pen for electronic equipment, for example, by accommodating the rear barrel in the front barrel again.
(22) The clip 4a attached to the rear barrel 3a by the screwing action of the tail crown joint 4b and the tail crown 4c can be easily removed from the rear barrel by releasing the screwing action.
(23) Even if the number of expansion / contraction operations of the touch pen for electronic devices is repeated, a predetermined frictional force is generated between the inner peripheral surface of the front barrel 2a and the large-diameter outer peripheral surface portion 3d of the slider 3b. Since it is ensured by the outward biasing action of each elastic member such as the ring spring 3j and the V-shaped spring 3k, it is possible to prevent the slider 3b from freely moving in the front-rear direction other than the user's expansion / contraction operation,
(24) A notch-like portion is formed on the slider opening side to which each elastic member such as the coil spring 3h, the C-shaped ring spring 3j, and the V-shaped spring 3k is attached, and the slider 3b is moved outwardly by the action of the elastic member. Making the displacement easy to occur, that is, making the generation of the predetermined frictional force of (23) more reliable,
Etc.

The assembly procedure of the illustrated electronic device touch pen is, for example,
(31) The rear ring 2j is press-fitted into the high outer peripheral surface 2e of the cylindrical shaft coupling 2b from the front to the rear end step portion 2g of the cylindrical shaft coupling.
(32) From the front of the lower outer peripheral surface 2d of the cylindrical shaft coupling 2b, the front shaft cylinder 2a with the grip 2h attached is press-fitted to the intermediate step portion 2f of the cylindrical shaft coupling.
(33) After the slider 3b (with the coil spring 3h, the C-shaped ring spring 3j, and the V-shaped spring 3k) and the tail crown joint 4b are attached to the front shaft cylinder 2a to which the cylindrical shaft coupling 2b is fixed from the front. The shaft cylinder 3a is inserted from its rear part, and the front cylinder 2a and the rear cylinder 3a are integrated.
(34) The clip 4a sandwiched between the tail crown joint 4b of the rear barrel 3a integrated with the front barrel 2a and the tail crown 4c is screwed with the hexagon socket bolt 4d and the tail crown joint. Fixed for
(35) From the front of the front barrel 2a integrated with the rear barrel 3a, the rear portion of the tapered shaft joint 1b to which the front ring 1d, the pennib 1a and the tapered cylindrical portion 1e are respectively attached is press-fitted. The sensor cooperating part 1 such as 1a is fixed to the front shaft acting part 2,
(36) Cover the tapered shaft joint 1b (tapered cylindrical portion 1e) attached to the front shaft cylinder 2a with the cap 1f.
It becomes such work.

  Note that the trailing ends of the clip 4a fixing work and the press-fitting work of the tapered shaft joint 1b in (34) and (35) are arbitrary.

  In the above (35), the taper shaft joint 1b enters the position where the annular rear end face of the front ring 1d press-fitted and held on the rear outer peripheral surface thereof abuts against the respective annular front end faces of the front barrel 2a and the grip 2h.

1 and 2 show the shortest state of a touch pen for electronic equipment.
At this time, since the annular front end surface 3c of the slider 3b is in contact with the annular rear end surface 1c of the tapered shaft joint 1b, the rear barrel 3a further moves forward from this contact state, or the front barrel 2a moves to the rear. There is no movement in the direction.

3 and 4 show the most extended state of the touch pen for electronic equipment.
At this time, since the annular step portion 3f of the slider 3b is in contact with the annular front end surface 2c of the cylindrical shaft coupling 2b, the rear shaft cylinder 3a is further moved backward from this contact state, or the front shaft cylinder 2a is It doesn't move forward. That is, the rear barrel 3a does not come out of the front barrel 2a.

  The slider 3b and the rear shaft cylinder 3a fixed to the slider 3b and the cylindrical shaft coupling 2b and the front shaft cylinder 2a fixed to the slider 3b and the front shaft cylinder 2a are extended from the shortest state of the electronic device touch pen by the user's expansion / contraction operation. It moves relatively to the state while resisting the so-called static friction force between the inner peripheral surface of the front cylinder and the outer peripheral surface (large diameter outer peripheral surface portion 3d) of the slider.

  Note that, due to the action of the static frictional force, the slider 3b and the rear barrel 3a do not freely move in the front-rear direction with respect to the front barrel 2 even when the electronic device touch pen is upright or inverted.

  To remove the clip 4a held between the tail crown joint 4b and the tail crown 4c from the rear barrel 3a, the hexagon socket head bolt 4d is rotated with a tool and the bolt and the tail crown joint 4b are screwed together. What is necessary is just to cancel | release a state (refer FIG. 5).

  Of course, it is also possible to attach the tail crown 4c to the tail crown joint 4b with the hexagon socket bolt 4d after the clip 4a is once removed from the rear barrel 3a (see FIG. 6).

  The slider 3b has its large-diameter outer peripheral surface portion 3d biased toward the inner peripheral surface of the front shaft cylinder 2a by its own elasticity.

  Each of the sliders of FIGS. 7B to 7D has a function of preventing the urging action from being lowered by the above-described “sagging” phenomenon, and includes a coil spring 3h, a C-shaped ring spring 3j, and a V-shape, respectively. By providing the internal spring 3k in the inside corresponding to the large-diameter outer peripheral surface portion 3d, a sufficient biasing action on the inner peripheral surface of the front shaft cylinder is secured.

Of course, the present invention is not limited to the above embodiments.
(41) As the sensor cooperating unit 1, an element that acts on various types of touch panels (position detection sensors) such as an electromagnetic induction method and a pressure sensitive method other than the electrostatic capacitance method is used.
(42) A slider is attached to the front shaft cylinder 2a, and a cylindrical shaft coupling is attached to the rear shaft cylinder 3a (for example, the front shaft operation section 2 and the rear shaft operation section 3 shown in the figure are respectively connected to the rear shaft cylinder 3a and the front shaft cylinder 2a. And replace under the dimension adjustment),
(43) The front barrel 2a is disposed inside the rear barrel 3a.
(44) As each component in each of the sensor cooperation part 1, the front shaft action part 2, the rear shaft action part 3 and the clip mechanism part 4, those made of various metals and synthetic resins other than the above are used.
