Abstract

PURPOSE:To facilitate operations of a stylus pen by tilting freely the pen point with the tip part of the pen main body defined as a fulcrum. CONSTITUTION:A stylus pen main body 1 has a hollow rod structure and has a constricted part 7 at its tip. A recess part 4a formed at the approximately center part of a pen point 4 is fitted at the part 7 of the main body 7. Thus the pen point 4 is supported with its tip side projected and its rear end side set into the main body 1. Under such conditions, the point 4 can be titled in any direction with the hooked part between the part 7 and the part 4a defined as a fulcrum. An electrode 2 is provided at the outer circumference of the rear end part of the point 4. In addition, an electrode 3 is provided opposite to the electrode 2 as it surrounded the electrode 2 formed inside the pen 1. A control spring 5 is also provided into the pen 1 to support the rear end of the point 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a stylus pen, and more particularly to a stylus pen that can be operated reliably even when held in the same way as when writing characters with a normal pen or the like.

[Prior Art] The configuration of a conventional stylus pen of this type is shown in Fig. 4(a).
, (b).

A conventional stylus pen includes a hollow stylus pen body 11, a pen tip 10 provided in the stylus pen body 11 so as to be freely retractable, an electrode 8 provided in the pen tip 10, and an electrode 8 provided in the stylus pen body 11. An electrode 9 that the electrode 8 contacts, and a control spring 12 that supports the pen tip 10
, and a lead wire 6 connected to the electrode 8.9. In a normal state, the pen tip 10 is positioned so as to protrude from the tip of the stylus pen body 11 by the control spring 12, and the electrodes 8 and 9 are in a non-contact state with each other. When the pen tip 10 is pushed against the control spring 12,
As shown in the figure, the pen tip 10 is sunk into the stylus pen body 11 and the electrodes 8 and 9 are in contact with each other.

FIG. 2 shows an example of how the conventional stylus pen is used, in which the stylus pen body 11 is pressed on the tablet surface 15 while keeping the stylus pen body 11 perpendicular to the tablet surface 15 as shown in the figure. Push the pen tip 10 in to bring the electrodes 8 and 9 into contact and turn them on. Furthermore, when the stylus pen body 11 is pulled up, the pen tip 10 returns to the protruding position by the force of the control spring 12, and the electrodes 8 and 9 are brought out of contact as described above.

[Problems to be solved] The conventional stylus pen described above must be operated by vertical movement while keeping the main body perpendicular to the tablet surface. In some places, you have to reach out and hold your wrist upright to keep the stylus pen in a vertical position, which is cumbersome and at the same time causes a lot of fatigue to your wrist.

■There are places where the pick-up point on the tablet surface is hidden behind the wrist, making it difficult to see and operate.

There was a drawback.

[Means for Solving Problems] The present invention has been made to solve the above-mentioned conventional problems, and in order to achieve this purpose, the tip of the stylus pen can be tilted freely using the tip of the stylus pen body as a fulcrum. Further, electrodes are provided inside the stylus pen main body and at the rear end of the pen tip, respectively, and are in contact with each other due to the inclination of the pen tip.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIGS. 1(a) and 1(b) are longitudinal sectional views of a stylus pen according to an embodiment of the present invention, respectively. The stylus pen of this embodiment includes a stylus pen body 1, a pen tip 4, electrodes 2 and 3, a control spring 5, and a lead wire 6. The stylus pen main body 1 has a hollow bar shape as shown in the figure, and a narrowed part 7 is formed at the tip thereof as shown in the figure. By engaging the concave portion 4a provided approximately in the center of the pen tip 4 with the constricted portion 7 of the stylus pen body 1, the tip side protrudes as shown in the figure, and the rear end side fits inside the stylus pen body 1. State supported. In this state, the pen tip 4 can tilt in any direction using the engagement portion between the narrowed portion 7 and the recessed portion 4a as a fulcrum.

An electrode 2 is provided on the outer periphery of the rear end of the pen tip 4, and an electrode 3 is provided inside the stylus pen 1 at a portion corresponding to the position of the electrode 2 so as to surround the electrode 2. Further, a control spring 5 that supports the rear end of the pen tip 4 is provided within the stylus pen body 1. This control spring 5 constantly pulls the rear end of the pen tip 4, as shown in FIG. 2(a).
As shown in FIG. 2, the electrode 2 is provided to maintain a non-contact state in which the electrode 2 is located concentrically with the electrode 3.

Next, the operation of the stylus pen of this embodiment will be explained. First, when using the stylus pen of this embodiment, as shown in FIG. Press the part 4 onto the tablet surface 15. When the pen tip 4 is pressed on the tablet 15, the pen tip 4 uses the concave portion 4a as a fulcrum as shown in FIG. 1(b).
As the pen tip 4 is tilted as shown in FIG. 2, the electrode 2 of the pen tip 4 comes into contact with the electrode 3 on the tablet main body 1 side, and becomes in an ON state.

Furthermore, when the pen tip 4 is separated from the tablet surface 15, the electrode 2 is separated from the electrode 3 by the force of the control spring 5, and the pen tip 4 is turned off.
Returns to the original state shown in .

In the above embodiment, the pen tip 4 is supported by the engagement of the constricted portion 7 and the recessed portion 4a, but the structure in which the pen tip 4 is tiltably supported on the stylus pen body 1 is not limited to this. Any structure may be used as long as it can be tilted freely.

[Effects of the Invention] As explained above, according to the present invention, the pen tip is provided so as to be tiltable with the tip of the stylus pen body as a fulcrum, and the above-mentioned pen tip is provided inside the stylus pen body and at the rear part of the pen tip. By providing electrodes that contact each other due to the inclination of the pen tip, the pen can be operated even when held in the same way as when writing with a normal pen, which has the effect of making stylus pen processing easier.
