していた。In the above-mentioned prior art, in the electric toothbrush of the kind represented by Japanese Patent Publication No. 52-43981, the toothbrush is simply moved by one of an axial linear reciprocating motion and a rotary reciprocating motion. The electric toothbrush of the type represented by Japanese Utility Model Application Laid-Open No. 61-60828 discloses a linear reciprocating motion in the axial direction.
It is possible to select any one of the revolving circular motion and the swinging reciprocating motion to perform the planar motion. However, the reciprocating motion in the axial linear reciprocating motion, which is considered to have the highest brushing effect on the teeth and gums, is possible. It is impossible to realize a three-dimensional movement by arbitrarily selecting a combination with the dynamic reciprocating motion and combining it in a complex manner. the dirt was completely removed had a problem such as Dzu leprosy.

After rotating S = 30 degrees, the engagement between the concave portion 26 and the contact piece 9 is released, whereby the contact piece 9 and the electrode plate 8A come into contact with each other. Voltage is supplied. In the drive mechanism 43, the rotation of the DC motor 6 is transmitted to the face gear 12 by the mesh between the pinion 11 and the outer peripheral gear portion 13, and the face gear 12 rotates about the rod pin 14 as an axis. At this time, as shown in FIG. 8, since the changeover switch 21 is interlocked with the switch knob 31 via the intermediate switch cover 24,
The longitudinal direction of the concave groove 22 and the axial direction of the toothbrush 41 are orthogonal to each other, that is, the toothbrush 41 is rotationally moved to a position where the longitudinal direction of the engaging groove 17 and the axial direction of the toothbrush 41 match. Accordingly, with the rotation of the face gear 12, the eccentric cam portion 15 simultaneously moves in the engagement groove 17 of the moving cam 16 while performing eccentric circular motion, and the convex portion 18 of the moving cam 16 The moving cam 16 moves in the direction perpendicular to the axial direction of the toothbrush 41 through the engagement between the eccentric cam portion 15 and the engagement groove 17 for sliding along the eccentric cam portion.
A reciprocating motion is performed in which the displacement is twice the amount of the eccentricity of 15. When the peripheral surface portion 19 of the moving cam 16 abuts on the inner periphery of the moving cam receiver 20, the moving cam receiver 20 is moved up and down by 15 degrees from the axial direction of the rod pin 14 by the reciprocating movement of the moving cam 16 in the horizontal direction.
In this case, the entire toothbrush 41 is only rotated and reciprocated, and is reciprocated with a rotational displacement amount of A = 15 degrees with respect to the axial rotation direction.

When "a" coincides with "bus" of the display section 45, as shown in FIG. 10, the changeover switch 21 rotates rightward by S = 60 degrees, and the contact piece 9 and the electrode plate 8A as in FIG.
And the power is supplied to the DC motor 6, and the face gear 12 rotates about the rod pin 14 as an axis. In this case, as shown in FIG. 11, the changeover switch 21 rotates to move the longitudinal direction of the concave groove 22 to the axial direction of the toothbrush 41, that is, the position where the longitudinal direction of the engaging groove 17 is orthogonal to the axial direction of the toothbrush 41. The convex portion 18 and the concave groove 22 of the moving cam 16
With this engagement, the moving cam 16 reciprocates in the axial direction of the toothbrush 41 with a displacement of twice the amount of eccentricity of the eccentric cam portion 15. That is, by the reciprocating motion of the moving cam 16 in the vertical direction, the moving cam receiver 20
The toothbrush 41 moves only up and down in the axial direction by a maximum of 1.35 mm, so that the entire toothbrush 41 moves only linearly and reciprocates back and forth with a displacement of L = 1.35 mm in the axial direction. .

When the switch is set to "mix" on the display section 45, as shown in FIG. 13, the changeover switch 21 is rotated to the right by S = 30 degrees, and the contact piece 9 and the electrode plate 8A are brought into contact with each other as in FIG. In contact therewith, power is supplied to the DC motor 6, and the face gear 12 rotates about the rod pin 14 as an axis. Then, as shown in FIG. 14, the changeover switch 21 is located at a position where the longitudinal direction of the concave groove 22 is inclined by 30 degrees from the axial direction of the toothbrush 41, that is, the longitudinal direction of the engaging groove 17 is inclined by 60 degrees from the axial direction of the toothbrush 41. The convex portion 18 of the moving cam 16 reciprocates along the concave groove 22. Therefore, in this state, the moving cam 16 reciprocates simultaneously in the axial direction of the toothbrush 41 and in a direction perpendicular to the axial direction. In other words, the moving cam 16 is reciprocated in the vertical direction to
20 moves up and down a maximum of 1.17 mm in the axial direction of the shaft 33 around the rod pin 14, and the moving cam receiver 20 moves left and right more than the axial direction of the rod pin 14 due to the reciprocating movement of the moving cam 16 in the horizontal direction. The toothbrush 41 is tilted by 6 degrees, and the toothbrush 41 performs an operation in which the linear reciprocating motion and the rotary reciprocating motion are combined. The displacement of the linear reciprocating motion of the toothbrush 41 is L = 1.17 mm.
On the other hand, the displacement of the rotary reciprocating motion of the toothbrush 41 is A
= 6 degrees.

可能となる。As described above, in the above embodiment, the moving direction of the moving cam 16 is determined via the changeover switch 21 of the angle adjusting mechanism 44 in accordance with the position of the switch knob 31.
Since the amount of action of the eccentric cam portion 15 in each direction is adjusted, if this moving direction does not coincide with the axial direction of the toothbrush 41 or a direction perpendicular to this axial direction, the driving mechanism 43 will move the toothbrush 41 in the axial direction. And the reciprocating motion of the shaft rotation direction,
Not only is it possible to perform a complex operation, but also by simply changing the position of the switch knob 31, it is possible to continuously switch the ratio of reciprocation between the axial direction and the axial rotation direction with respect to the toothbrush 41, The brushing effect can be enhanced, and the movement direction of the toothbrush 41 can be freely used depending on the user's preference and intended use.
