Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a ballpoint pen/electric stimulator in which an electric stimulator having a piezoelectric unit is incorporated into a ballpoint pen.

(Prior Art) As a conventional electric stimulator, a piezoelectric unit consisting of an impact member and a piezoelectric element body is housed in a hollow holding cylinder, and a part of the actuating member for pressing the piezoelectric unit is attached to the holding cylinder. The piezoelectric unit is provided so as to protrude from the rear end of the body, and when the actuating member is pressed, the piezoelectricity generated in the piezoelectric unit is discharged to the human body through the discharging portion at the tip of the conductor that protrudes forward of the piezoelectric unit, thereby causing the human body to It is known that it was designed to stimulate people (see Utility Model Publication No. 60-935).

(Problems to be Solved by the Invention) However, the above-mentioned conventional devices had the problem that their only purpose was medical purposes, and their scope of use was narrow.

(Means for solving the problems) The present invention attempts to solve the above problems by incorporating an electric stimulator into a ballpoint pen so that it can be used for both writing and medical purposes. A piezoelectric unit consisting of an impact member and a piezoelectric element body is housed in a hollow holding cylinder, and an operating member for pressing the piezoelectric unit is provided with a part thereof protruding from the rear end of the holding cylinder. , an insulating cartridge having a conductive ink tank is provided with its pen tip protruding from the tip of the holding cylinder, and a conductor guides piezoelectricity generated in the piezoelectric unit when the actuating member is pressed to the ink tank. A conductive lid is detachably attached to the nib of the pen.

(Function) The present invention has the above configuration. According to this, when the lid at the tip is brought into contact with the skin and the operating member at the rear end is pressed, the impact member impacts the piezoelectric element body, causing the piezoelectric element body to Piezoelectricity is instantaneously generated and discharged to the skin via a conductor and a conductive ink tank, so it can be used as an electrical stimulator, and when the lid is removed, the pen tip is exposed, allowing it to be used as a ballpoint pen. Can be used.

(Example) Next, an example of the present invention will be described based on the drawings.

FIG. 1 shows the case of use as an electric stimulator, in which numeral 1 is a hollow holding cylinder having a clip 2 on its outer circumferential surface, and a piezoelectric unit 3 is provided inside the holding cylinder at a position slightly near the rear end.

The piezoelectric unit 3 consists of a piezoelectric element main body 4 and an impact member 5 behind it. It is fixed by press-fitting the fixed holding part 4a into the insulating cylinder 6 formed along the inner circumferential surface of the cylinder 1.

Under normal conditions, the impact member 5 is urged toward the rear end of the holding cylinder 1 by the force of a spring wound around an inner shaft (not shown) and comes into contact with the actuating member 7. It is biased toward the end.

The actuating member 7 presses the piezoelectric unit 3 and has its rear end protruding from the rear end of the holding cylinder 1. This actuating member 7 moves the impact member 5 forward against the force of the spring by pushing its rear end with a fingertip, and has a stepped portion 7a on its outer peripheral surface.
By engaging this stepped portion 7a with a protrusion 1a provided on the inner circumferential surface of the rear end of the holding cylinder 1, it is possible to prevent it from coming off when the pressure on the rear end is released. did.

Reference numeral 8 denotes an insulating cartridge having a conductive ink tank 9 in its center, with its pen tip 9a protruding from the tip of the holding cylinder 1.

A lead wire 10 is a conductor for guiding the piezoelectricity from the piezoelectric element to the ink tank 9, and a holding portion 10a at the tip thereof is screwed and fixed to the rear end of the cartridge 8.

Reference numeral 11 denotes a conductive lid, which is removably engaged with and fitted into a small groove 9b formed at the base of the pen tip 9a.

FIG. 2 shows the case where it is used as a ballpoint pen. In this case, the lid 11 is not needed, so a fitting groove 7b is provided at the rear end of the actuating member 7, and the removed lid 11 is fitted into this. I put it in there so I wouldn't lose it.

To do this, fit the lid 11 onto the pen tip 9a, press it against the skin, and then press the operating member 7 at the rear end with your fingertip. It enters the main body 4 and impacts the piezoelectric element to generate piezoelectricity, that is, high voltage, which is discharged to the skin via the lead wire 10, ink tank 9, pen tip 9a, and lid 11. This electrical discharge stimulates the human body and makes you feel good.

3 and 4 show another embodiment of the present invention, in which a cover 11 is detachably provided on the pen tip 9a.
This embodiment is not particularly different from the embodiment shown in FIGS. 1 and 2, except for the fact that it is constituted by a cap with a clip and that a push spring 12 is provided which urges the actuating member 7 toward the rear end side together with the spring of the impact member 5.

In FIG. 3, 11a is a conduit that is fitted into the pen tip 9a and guides the high voltage generated by the piezoelectric element to the discharge section 11b, and 11c is a conduit that connects the discharge section 11b to the cap body 1.
1d is an intermediate member for insulating, 11e is a conduit 1
A fixing member formed along the outer peripheral surface of 1a for fixing intermediate member 11c is shown.

Incidentally, in the two embodiments described above, a clip 2 is attached, making it even more convenient to carry.

(Effects of the invention) As described above, the present invention combines an electric stimulator and a ballpoint pen, so it can be used not only as a medical instrument but also as a writing instrument, unlike the conventional one that is used only as a medical instrument. It has the effect of expanding the scope of use compared to the previous model, especially since ballpoint pens are usually carried by office workers, test takers, and other ordinary people, so there is no portability inconvenience such as having to carry an electric stimulator separately. It has the effect of eliminating

In addition, when office workers feel tired while working or test takers study, they can use it as an electric stimulator to relieve stress by simply attaching the cap to the pen tip. It has a convenient effect.
