Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electronic acupuncture device that doubles as a ballpoint pen by incorporating a piezoelectric unit in the barrel of the ballpoint pen.

[0002]

[Prior art]

 An electronic acupuncture needle that doubles as a ballpoint pen is already known as Japanese Utility Model Publication No. 2-46366, in which a ballpoint pen refill is connected to a discharge lead wire of a piezoelectric unit mounted in a shaft cylinder, and in a normal state, the shaft is normally used. A conductive lid is attached to the projecting portion of the refill projecting from the tip of the cylinder for use as an electronic needle, and the lid is removed for writing.

[0003]

[Problems to be solved by the device]

 The above-mentioned conventional one requires a lot of work to attach and detach the lid piece or the cap each time when using it as an electronic acupuncture needle and when using it for writing, and in the case of a small lid piece, the procedure after removing it is required. There is a risk that it may be lost due to inconvenience, and there is an inconvenience that the fingertips are soiled when attaching / detaching, and there is a disadvantage that the attachment / detachment is troublesome.

[0004]

[Means for Solving the Problems]

 In view of the above, the present invention has an object to make it extremely easy to use as an electronic acupuncture needle or for writing. In the shaft cylinder 1 having the front half as a rotation shaft cylinder, a shaft cylinder is provided. It is equipped with a voltage unit that discharges with a pressure actuator provided at the rear end of the rotary shaft cylinder. The tip of the rotating shaft tube is inserted into the skin acupuncture needle by the rotation of the cylinder, and a ballpoint pen refill made of a conductive material that protrudes and retracts from the front end of the needle is connected to the lead wire for discharge of the piezoelectric unit. It will be done.

[0005]

In the present invention, as shown in FIG. 1 of the embodiment, the tip of the refill 6 is projected from the skin acupuncture needle 5 at the tip of the rotary shaft cylinder 2 to be used as a ballpoint pen for writing. When the rotary shaft cylinder 2 is relatively rotated, the projection 12 and the spiral cam groove 11 are engaged with each other, so that the cam cylinder 8 integrated with the refill 6 is retracted inward as shown in FIG. The tip of the film 6 is immersed, and the skin acupuncture needle 5 can be brought into contact with the human body in the proper position a. In this contact pressure state, the pressing actuator 4 at the rear end of the barrel 1 is pressed to cause the piezoelectric unit 3 to move. The discharge voltage can be applied to the human body a from the lead wire 7 through the refill 6 and the skin acupuncture needle 5, and thus, the refill 6 can be retracted and retracted by the rotation of the rotation shaft cylinder 2 in this way to change the electronic needle and the writing. Used for.

【Example】

 An embodiment of a ballpoint pen / electronic acupuncture device according to the present invention will be described with reference to FIGS.

In the drawings, reference numeral 1 denotes a ball-point pen barrel having a rotating barrel 2 in the front half thereof, and the rotating barrel 2 is rotatable with respect to a non-conductive connecting member 1 a integrally fixed to the barrel 1. And so as not to separate at the joint portion 1b. In addition, 10 is a clip for carrying.

An impact-type piezoelectric unit 3 is immovably accommodated and mounted in an upper position of the connecting member 1a in the shaft cylinder 1, and a pressing actuator 4 provided at a rear end of the shaft cylinder 1 is pushed to push the piezoelectric unit 3 in place. The operation portion 3a is pressed against a spring (not shown) so as to generate a piezoelectric force by applying an impact to the internal piezoelectric element. Return.

The rotating shaft cylinder 2 in the front half of the shaft cylinder 1 is made of a non-conductive material, and a cylindrical skin acupuncture needle 5 made of a conductive material is attached to the tip thereof to form the tip of the ballpoint pen. A refill 6 of a ball-point pen is inserted into the connecting member 1a and the skin acupuncture needle 5 and housed in the center of the inside of the rotary shaft cylinder 2, respectively.

In the illustrated example, the refill 6 is detachably inserted into and attached to a conductive support tube 9 which is integrally bonded by inserting the center of a cam cylinder 8 described later, and the refill 6 is appropriately used as a consumable item. As shown in FIG. 3, the cam cylinder 8 is made replaceable, and a convex portion 8a is integrally formed thereabove, and the convex portion 8a is fitted into the concave portion 1c of the connecting member 1a. 8 is rotated integrally with the connecting member 1a, but is coupled so as to be movable in the axial direction. Therefore, the refill 6 inserted into the support tube 9 integral with the cam barrel 8 forms the shaft barrel 1 together with the cam barrel 8. Although the shaft cylinder 1 and the cam cylinder 8 can be connected to each other in the axial direction, other mechanisms such as spline engagement and key engagement can be adopted without being limited to the above-mentioned connecting means.

The base end side of the refill 6 into which the support tube 9 is inserted and bonded is connected to the screw portion of the discharge lead wire 7 of the piezoelectric unit 3 in the upper recess of the connecting member 1 a via the conductive support tube 9. , And the tip of the refill 6 was internally inserted into the skin acupuncture needle 5 so that the piezoelectric unit 3 and the skin acupuncture needle 5 were always in an electrically conductive relationship.

A spiral cam groove 11 is formed on the outer periphery of the cam barrel 8, and this is engaged with a projecting piece 12 projecting from the inner surface of the rotary shaft barrel 2. As shown in FIG. 3, the protrusion 12 is formed by recessing the inner surface of the annular piece 13 so that the annular piece 13 is engaged with the inner peripheral surface of the movable barrel 2 by a protrusion 13a provided on the outer surface thereof. It is attached so as to rotate integrally with the movable shaft cylinder 2, and as described above, it is attached to the annular groove forming the coupling portion 1b surrounding the outer periphery of the connecting member 1a of the shaft cylinder 1. The projection 13b is inserted into the spiral cam groove 12 of the cam cylinder 8 so as to be rotatable relative to the rotary cylinder 1 together with the rotary cylinder 2 by the projection 13b. .

When the spiral cam groove 11 and the protrusion 12 are engaged with each other, the refill 6 is moved by a predetermined amount together with the cam barrel 8 by the relative rotation of either one of them. When the shaft cylinder 1 is rotated by grasping the hand firmly, the cam cylinder 8 and the refill 6 rotate and move in the engagement relationship between the cam groove 11 and the projecting piece 12, and the tip of the refill 6 is moved. It is possible to project and retract from the front end of the skin acupuncture needle 5, and it is possible to easily switch between writing as a ballpoint pen and electronic needle.

In the illustrated example, the tip end of the refill 6 is projected and retracted by rotating the barrel 1 approximately once, but the amount of rotation can be set arbitrarily.

[0015]

[Effect of device]

 According to the present invention, the shaft cylinder equipped with the piezoelectric unit and the refill for the ballpoint pen is simply rotated to project and retract the tip of the refill from the tip, thereby switching between the ballpoint pen and the electronic acupuncture. It has the effect that it is extremely easy to handle.
