The rotation speed detection holes S are formed to pass through the corresponding rotation speed detection sensors 72 when the second rotary plates 61 are rotated by the second drive motors 62.
  • the corresponding rotation speed detection sensor 72 detects the number of the rotation speed detection holes S that pass through the rotation speed detection sensor 72.

From this position, when the second rotary plates 61 are rotated and the count value of each rotation speed detection sensor 72 reaches another one half of the total number of the rotation speed detection holes S of the corresponding rotary plate 61 (i.e., reaches the total number), the first rotary plates 13 are closest from each other.

  • the present embodiment has the advantages described below.
  • a scalp care device 10 of the ninth embodiment is obtained by eliminating the control unit 19 from the scalp care device 10 of the first embodiment and coupling an elliptic drive gear 94 to the rotation shaft 17a of the first drive motor 17. As shown in Fig. 12(b) , the rotation shaft 17a is coupled at a position slightly separated along the major axis of the drive gear 94 relative to the ellipse of the drive gear 94.
  • the drive gear 94 is engaged with an elliptic driven gear 95.

  • the support shaft 95a is coupled at a position slightly separated along the major axis of the driven gear 95 relative to the ellipse center of the driven gear 95.
  • the first drive motor 17 rotates the drive gear 94 at a constant rotation speed.
  • the rotation of the drive gear 94 is transmitted to the driven gear 95. This rotates the driven gear 95 and thereby rotates the first rotary plate 13.
  • the gear 94 is elliptic.
  • the rotation angle of the driven gear 95 per rotation angle of the driven gear 94 differs between a state in which the major axis side of the drive gear 94 engages with the minor axis side of the driven gear 95 ( Fig. 12(b) ) and a state in which the minor axis side of the drive gear 94 engages with the major axis side of the driven gear 95 ( Fig. 12(c) ). More specifically, in a state in which the major axis side of the drive gear 94 engages with the minor axis side of the driven gear 95, rotation of the drive gear 94 increases the rotation speed of the driven gear 95. This increases the rotation speed of the first rotary plate 13. Further, as shown in Fig.

  • the third terminal 85c is connected to the resistor 84 via a slide contact 83 that slides and moves integrally with a weight 82 arranged in the inclination sensor 81.
  • the weight 82 swings about a rotation shaft 86 and the slide contact 83 slides and moves integrally with the slide contact 83.
  • the resistance between the slide contact 83 and the first terminal 85a or second terminal 85b changes. The resistance is detected at the third terminal 85c.
  • the control unit 19 calculates the inclination of the scalp care device 10 and controls the radius adjustment drive unit 65 based on the calculated value (inclination) to change the rotation radius of the first rotary plate 13 about the axis L3 of the second rotary plate 61. As a result, the control unit 19 controls the radius adjustment drive unit 65 in accordance with the angle detected by the inclination sensor 81. Thus, the user is massaged in accordance with the movement of the scalp that contacts the massager member 12 without the user being aware.
  • control unit 19 may control the second drive motor 62 to switch the rotation direction of the second rotary plate 61. This allows the second rotary plate 61 to be rotated in the clockwise and counterclockwise directions.
  • the first rotary plate 13, the massager member 12, and the first drive motor 17 can be rotated as a single unit about the axis L3 of the second rotary plate 61.

  • the second rotary plates 61 are rotated at the same speed by using the two second drive motors 62 and controlling each second drive motor 62 with the control unit 19 but not limited in such a manner.
  • the rotation shaft 62a of the second drive motor 62 may be coupled to the drive gear 91.
  • the drive gear 91 may be coupled to an orbiting gear 92 and a driven gear 93.
  • the driven gear 93 may be engaged with a further orbiting gear 92, which differs from the orbiting gear 92 engaged with the drive gear 91.
  • the first drive motor 17 is arranged on one surface of each orbiting gear 92.
