  In the state where the scalp care device 10 is gripped, the back surface of the finger or the back of the hand is pressed toward the grip surface 15 by the reaction force that hits the inner peripheral surface of the arch portion 14. The upper end portion including the gripping surface 15 can be firmly gripped.

  In the present embodiment, a plate-like panel member 17 formed in a convex arc shape is attached to the concave portion 13 c formed in the central region of the upper surface 13 b of the main body housing 13. The peripheral edge portion of the surface of the panel member 17 and the peripheral edge portion outside the concave portion 13 c on the upper surface 13 b of the main body housing 13 are substantially flush with each other.

  In this example, the surface of the panel member 17 occupies most of the gripping surface 15 including the upper surface 11 b of the apparatus main body 11. When the scalp care device 10 is gripped, the abdomen and palms of a plurality of fingers inserted into the finger insertion hole 16 are placed on the gripping surface 15 and the first joint or the second joint of the plurality of fingers is advanced. Is placed on the front surface 11c of the apparatus main body 11, and the thumb is attached to one side surface 11a (for example, the side shown in FIG. 3).

In the present embodiment, the main body housing 13 and the panel member 17 constitute an example of a housing.
As shown in FIGS. 1 and 3, an operation panel 20 having a vertically long rectangular shape is provided on one side surface 11 a of the apparatus main body 11. The operation panel unit 20 includes a switch operation member 22 that is operated when the scalp care device 10 is operated, and a plurality of LED indicator lamps 23 that notify the user of the operation mode of the scalp care device 10 by lighting.

The plug terminal 39a protrudes to the back side in the insertion hole 18 formed in the back surface 11d of the apparatus main body 11, and is exposed to the outside.

  The plug terminal 39a is connected to a connector (not shown) of a cable that is connected to an external power source, so that the storage battery 33 (see FIGS. 7 and 8) built in the apparatus main body 11 is charged. Is possible.

  On the other hand, as shown in FIGS. 1 and 9, the treatment head portion 12 attached to the lower end portion of the apparatus main body portion 11 includes a cover portion 61 attached to close the lower end opening of the main body housing 13, and a cover portion. A plurality of (four as an example) surgical elements 71a to 71d that are provided at a plurality of locations (as an example, four locations) on the lower surface portion 61 and rotate eccentrically at different phases.

  The surgical elements 71a to 71d include a bottomed cylindrical surgical element base 72 and a plurality (for example, four) of surgical protrusions protruding in a vertical direction (downward) from the lower surface (bottom surface) of the surgical element base 72. 73.

  The plurality of treatment elements 71a to 71d are driven so as to be carried downstream in the operation direction X while sandwiching the scalp by rotating eccentrically around the central axis at different phases. For example, when the user touches the scalp care device 10 against his / her temporal region, it is preferable to hold the scalp care device 10 so that the movement direction X is in the lift-up direction (the direction toward the top of the head). An example.

  For this reason, in the scalp care device 10 of the present embodiment, three or four fingers other than the thumb of the hand are fingers between the arch portion 14 and the gripping surface 15 with the palm facing downward against the gripping surface 15. It is assumed that the insertion hole 16 is inserted and gripped in the finger insertion direction ID indicated by the arrow in FIG.

When the scalp care device 10 is gripped by this assumed gripping method, the longitudinal direction of the three or four fingers of the gripped hand becomes parallel to the movement direction X.
In addition, the direction of the fingertips of the three or four fingers of the gripping hand coincides with the operation direction X of the scalp care device 10. When a user massages the scalp with the fingertips of fingers holding the scalp care device 10 facing upward and applying a plurality of surgical elements 71a to 71d to his / her right and left heads, the surgical element 71a The operation direction X of ˜71d is the lift-up direction.

  Further, when the user wants to massage the occipital region in the lift-up direction, if the user takes a massage posture in which the hand is turned to the occipital region over the head (or over the shoulder), the fingertip direction of the hand holding the scalp care device 10 (that is, the operation direction X) ) Will face down.

  In this case, the scalp care device 10 is gripped by inserting three or four fingers from the opposite side of the finger insertion direction ID so that the movement direction X is the lift-up direction. In any case, in order to massage the scalp so that the movement direction X becomes the lift-up direction, it is necessary to recognize which direction the movement direction X is.

In the present embodiment, since the extending direction of the arch portion 14 is orthogonal to the operation direction X, it can be recognized that the direction orthogonal to the extending direction of the arch portion 14 is the operation direction X.
Furthermore, in order to recognize the movement direction X of the scalp care device 10 to that direction, it is necessary for the user to recognize that the arrow direction shown in FIG. 1 is the finger insertion direction ID. Therefore, in this embodiment, in order to make the user recognize that the direction indicated by the arrow in FIG. 1 is the finger insertion direction ID, in addition to the device of the extending direction of the arch part 14, the inner peripheral surface of the arch part 14 The shape of the gripping surface 15 is devised.

  Here, in order to explain the device of the above shape, each surface constituting the outer peripheral surface of the main body housing 13 is defined as follows. The extended proximal end side surface (arch installation surface) on which the arch portion 14 is extended is the side surface 13d, the surface located on the downstream side in the operation direction X of the treatment head portion 12 is the front surface 13e, and the apparatus main body portion 11 is defined as a back surface 13f, which is a surface facing the front surface 13e of 11 and located on the upstream side in the operation direction X of the treatment head portion 12.

  As shown in FIG. 6, the upper surface of the apparatus main body 11, that is, the gripping surface 15 (main body upper surface) on which the abdomen of the finger and the palm are placed when the user grips, has a convex arc shape in the side view shown in FIG. Formed on the surface.

  6, the upper end portion 13g on the front surface 13e side (hereinafter, referred to as “front upper end portion 13g”) on the upper surface 11b (that is, the gripping surface 15) of the apparatus main body 11, and the rear surface on the upper surface 11b. An upper end portion 13h on the 13f side (hereinafter referred to as “back upper end portion 13h”) is disposed at a lower position than the upper surface central portion 15a that is the central portion of the upper surface 11b in the operation direction X (that is, the finger insertion direction ID). Yes.

For this reason, when a palm or the like is placed on the gripping surface 15 and gripped, the palm is formed in a convex arc-shaped surface that is easy to grip, and the user can easily grip the scalp care device 10.
Further, the gripping surface 15 which is an example of the outer surface of the housing formed in a convex arc shape is a surface of a portion located on the finger insertion direction ID side (the entrance side of the finger insertion direction ID) with respect to the upper surface central portion 15a in the finger insertion direction ID. It is formed so that the curvature of the surface of the part located on the opposite side (exit side) of the finger insertion direction ID is larger than the curvature of.

  For this reason, when a finger is inserted from an inappropriate direction opposite to the finger insertion direction ID, it is possible to give a discomfort due to the difference in curvature of the gripping surface 15 to the palm placed on the gripping surface 15. . In this case, the user can recognize that the insertion direction is inappropriate from the uncomfortable feeling of the palm placed on the gripping surface 15 and insert the finger again from the appropriate finger insertion direction ID. The scalp care device 10 can be gripped by the gripping method.

  Further, as shown in FIGS. 4 and 5, finger insertion on the gripping surface 15 is performed on the gripping surface 15, which is an example of the main body outer surface facing the arch portion 14, as viewed from the operation direction X side of the surgical elements 71 a to 71 d. A convex portion 15c bulging into a convex curved surface is formed at the center of the surface of the portion located on the entrance side of the direction ID.

  The convex portion 15c is a depression formed at the center of the palm placed on the gripping surface 15 when the user places the palm along the convex arc-shaped surface of the gripping surface 15 and grips the scalp care device 10 with a finger. Are formed in a convex shape corresponding to the concave shape of the recess.

  For this reason, when the user grips the scalp care device 10 with a finger, the palm can naturally wrap around the gripping surface 15. When the insertion direction of the user's finger is inappropriate, it can be recognized that the insertion direction is inappropriate from the uncomfortable feeling of the palm when the upper part of the apparatus main body 11 is gripped.

For this reason, it becomes possible for the user to easily recognize the operation direction X of the surgical elements 71a to 71d and to hold the scalp care device 10 by an appropriate holding method.
2, 4, and 5, when the gripping surface 15 is viewed from the front surface 13 e and the back surface 13 f, as illustrated in the front view of FIG. 2 and the rear view of FIG. ) Is formed in a concave arc shape at the central portion 15b in the width direction.

  For this reason, the center part of the width direction of the finger insertion hole 16 formed between the arch part 14 and the holding surface 15 is relatively widely secured in the vertical direction. Here, the central portion 15b forms a concave arc shape at the central portion in the width direction of the gripping surface 15, and the concave arc-shaped surface portion extends from the upper surface central portion 15a of the gripping surface 15 both forward and backward. It extends.

  In the central portion 15b, the center line of the gripping surface 15 extending from the upper surface central portion 15a to the front upper end portion 13g (that is, the width center line of the concave arc-shaped central portion 15b) has a convex shape. For this reason, it is possible to grasp the finger in a state where the finger naturally wraps the grasping surface 15 when grasped by the user's finger. Thereby, the operation direction X of the treatment elements 71a to 71d can be recognized more easily.

  As shown in FIGS. 2 and 4, in the width direction orthogonal to the operation direction X, the side end portion 13 i that becomes the root portion of the arch portion 14 is disposed at a higher position than the central portion 15 a of the gripping surface 15. Yes. For this reason, the gripping surface 15 has a surface shape that matches the palm shape.

  Further, as shown in FIGS. 2 and 4, in the portion near the base of the arch portion 14, the inner peripheral surface slightly above the gripping surface 15 changes from a gradually expanding portion to a portion that no longer spreads. There is a place. This part is called a curvature change point Pv in the front view (FIG. 2) and the back view (FIG. 4).

  This curvature change point Pv is set at a position higher than the side end portion 13 i that is the base portion of the arch portion 14. By setting the curvature change point Pv to a position higher than the side end portion 13i, the width direction intersecting the finger insertion direction ID of the finger insertion hole 16 on the lower side of the arch portion 14 (the horizontal direction in FIGS. 2 and 4). In FIG. 3, a relatively wide finger insertion area is secured.

  For this reason, it becomes possible to arrange | position two fingers of both ends among the several fingers inserted in the finger insertion hole 16 to the side edge part 13i vicinity which is a root part in the internal peripheral surface of the arch part 14. FIG. The finger insertion hole 16 can be used widely and effectively. Further, it is possible to avoid the back surfaces of the two fingers positioned at both ends in the width direction among the plurality of fingers inserted into the finger insertion hole 16 from coming into contact with the inner peripheral surface of the arch portion 14.

  As shown in FIGS. 1, 4, and 5, the panel member 17 is attached in a detachable state by locking while being fitted in a recess 13 c formed in the upper surface 13 b of the main body housing 13. . A projection 17a that is operated when the panel member 17 is removed is formed at the end of the apparatus main body 11 on the back side.

  As shown in FIG. 6, a locking projection 17 b is projected in the vicinity of the rear surface side of the projection 17 a in the panel member 17, and this locking projection 17 b is located at a corresponding position on the upper surface 13 b of the main body housing 13. It engages with the formed locking recess 13j.

  And the panel member 17 is engaged with the upper end side of the main body housing 13 so that attachment or detachment is possible in the up-down direction (axial direction) by the snap-fit engagement of the latching protrusion 17b and the latching recessed part 13j. The user can remove the snap fit engagement by pushing the protrusion 17a upward, and remove the panel member 17 from the main body housing 13.

As a result, when the panel member 17 becomes dirty, or when the recess 13c on the back side of the panel member 17 becomes dirty, the panel member 17 can be removed and cleaned.

As shown in FIG. 6, the motor 32 is disposed on the upper surface of the motor base 30 in a posture in which the base surface (motor installation surface) and the axis are parallel. In the vicinity of the pinion gear 32b fixed to the tip of the output shaft 32a of the motor 32, a cylindrical transmission gear 42 is provided in which the pinion gear 32b and the rotation axis are arranged in a direction orthogonal to each other.

  The transmission gear 42 has gear portions on the upper end surface and the outer peripheral surface, and the pinion gear 32b meshes with an annular gear portion formed on the upper end surface of the transmission gear 42. The pinion gear 32b and the transmission gear 42 constitute an orthogonal conversion mechanism that transmits the rotation by converting the axial direction of both rotations into an orthogonal direction.

  The rotation of the transmission gear 42 shown in FIG. 6 constitutes the final stage of the speed reduction mechanism 41 via the intermediate gear group of the speed reduction mechanism 41 including other gears meshed with the gear portion on the outer peripheral surface thereof. The four final gears 46a to 46d shown in FIG. As shown in FIG. 8, a connection shaft 47 is disposed at the center axis position of each of the final gears 46a to 46d so as to be integrally rotatable by press-fitting or insert molding.

  As shown in FIG. 8, each connecting shaft 47 is inserted into a waterproof base 50 and a metal pressing plate 51 arranged on the lower surface side in a state of being sealed with an O-ring (not shown). The waterproof base 50 has a slightly smaller shape than the substantially rectangular opening 13a of the main housing 13, and is fitted into the opening 13a of the main housing 13 in a sealed state. The waterproof base 50 and the pressing plate 51 are fixed to the main body housing 13 with screws.

  As shown in FIG. 8, the lower ends of the connecting shafts 47 that can rotate integrally with the final gears 46a to 46d (only two are shown in the figure) are connected to the corresponding rotation bases 55 respectively. It is attached at a position shifted radially outward from the center line. The center axis of the rotation base 55 is press-fitted and fixed with the output shaft 56 protruding downward.

For this reason, the output shaft 56 is set to rotate around the connecting shaft 47 at a position deviated from the axial center of each of the final gears 46a to 46d.
On the other hand, the treatment head portion 12 detachably provided on the apparatus main body portion 11 configured as described above is driven by receiving the driving force of the cover portion 61 that closes the opening portion 13 a of the main body housing 13 and the motor 32. Surgical elements 71a to 71d. The cover 61 is made of a flexible member such as an elastomer, and is set to have the same shape and size as the opening 13 a of the main body housing 13.

  As shown in FIGS. 6 and 7, the cover 61 has a head base that is made of a harder material and has a plurality of openings into which a plurality of substantially cylindrical treatment element bases 70 can be inserted. Part 62 is attached. The head base 62 is engaged with the waterproof base 50 in the vertical direction by snap fitting. A cover 61 is attached to the head base 62 by fitting.

As shown in FIGS. 6 and 7, a support device 67 that restricts the vertical movement (axial direction) of each treatment element base 70 is provided on the upper surface side of the central portion of the head base portion 62.
The base end portions of the support device 67 are inserted at different height positions so that the same number (four in this example) of substantially flat connecting members 68 as the surgical element base 70 extend in four directions. In addition, a U-shaped portion formed at the distal end portion of each connecting member 68 extending in all directions is engaged with a circumferential groove on the outer peripheral surface of each treatment element base 70. This restricts the movement of each surgical element base 70 in the vertical direction (axial direction).

  As shown in FIG. 8, the four output shafts 56 fixed to the respective rotation center positions of the four rotation bases 55 are fitted in each treatment element base 70. When the rotary base 55 rotates about the connecting shaft 47, the treatment element base 70 makes a revolving motion together with the output shaft 56 fixed at a position shifted in the radial direction from the center of the rotary base 55. . Each treatment element base 70 is assembled with treatment elements 71 a to 71 d integrally formed with the cover portion 61.

  As shown in FIGS. 8 and 9, the treatment elements 71 a to 71 d are flexible members such as an elastomer similar to the cover part 61 and are integrally formed with the cover part 61. As shown in FIG. 8, the four surgical elements 71 a to 71 d are connected to a connecting shaft 47 arranged in a substantially square shape in plan view via a rotation base 55, an output shaft and a surgical element base 70, respectively. They are arranged at positions that form four vertices of a substantially square in a bottom view shown in FIG.

  As shown in FIGS. 8 and 9, the surgical elements 71 a to 71 d extend downward from a bottomed cylindrical surgical element base 72 to which the surgical element base 70 is attached and from the lower surface of the surgical element base 72. And a plurality of treatment protrusions 73. Further, three small-diameter projections 73 a shown in FIG. 8 are formed at the distal end of the treatment projection 73.

  As shown in FIG. 8, the distal end portion (lower end portion) of each surgical element base 70 is fitted to each surgical element base portion 72. In this embodiment, as an example, the cover 61 and the treatment element 71a are filled by filling the resin material constituting the cover part 61 and the treatment elements 71a to 71d in a state where the treatment element base 70 is arranged in the mold. ˜71d is configured integrally with the treatment element base 70 by two-color molding.

  As shown in FIGS. 1 and 9, a follower deforming portion 61 a of the cover portion 61 is provided around the treatment element base portion 72 constituting the treatment elements 71 a to 71 d. The follower deforming portion 61a is configured to be concave on the opposite side to the treatment protrusion 73 of the treatment elements 71a to 71d and to be elastically deformable in a direction perpendicular to the vertical direction (axial direction).

  For this reason, even if the surgical element base 72 is moved in the direction perpendicular to the vertical direction (axial direction) by the surgical element base 70, the surgical elements 71a to 71d are allowed to move and are deformed to follow the movement. The The follow-up deforming portion 61a may have a bellows shape.

Next, the operation of the scalp care device 10 configured as described above will be described.
The extending direction of the arch part 14 provided in the scalp care device 10 is a direction orthogonal to the operation direction X of the scalp care device 10. Therefore, the user can recognize the operation direction X from the extending direction of the arch part 14.

  However, even if the user is not particularly conscious of the extending direction of the arch part 14, the user inserts three or four fingers other than the thumb into the finger insertion hole 16 between the arch part 14 and the upper surface 11b to grip the palm. If the upper surface of the apparatus main body 11 is gripped on the surface 15, the scalp care device 10 can be gripped in a gripping direction in which the longitudinal direction of the three or four fingers substantially coincides with the movement direction X.

  At this time, in normal use, such as when scalp care is performed on the temporal region, for example, three or four fingers are inserted into the finger insertion hole 16 from the finger insertion direction ID to grip the upper surface portion of the apparatus main body 11. In this normally used gripping direction, the thumb is positioned on the operation panel unit 20 side, and the switch operating member 22 can be operated using the thumb of the hand on the gripped side.

  When the switch operation member 22 is pressed by the user, the switch portion 24a is switched between on and off, and when turned on, the motor 32 is driven to rotate the surgical elements 71a to 71d. Accordingly, when the driving force of the motor 32 is transmitted via the speed reduction mechanism 41, the surgical elements 71a to 71d of the surgical head unit 12 are operated around the connecting shaft 47.

  When the treatment protrusion 73 (protrusion 73a) of the treatment elements 71a to 71d is brought into contact with the scalp, the user's scalp is moved in accordance with the movement of the treatment protrusion 73, and the scalp is cared for (massaged). Become. At this time, the surgical elements 71a to 71d operate to move the scalp in one direction from the operation of the gears 42, 46a to 46d and the arrangement relationship of the rotation base 55.

  Here, the rotation operation of the treatment elements 71a to 71d provided in the scalp care device 10 will be described in detail mainly with reference to FIG. In addition, in FIG. 9, the bottom view when the scalp care apparatus 10 is seen from the downward direction is shown. In FIG. 9, the direction orthogonal to the paper plane corresponds to the vertical direction, and the horizontal direction in the figure is the horizontal direction of the scalp care device 10, and the vertical direction in the figure is the front-back direction.

  The four surgical elements 71a to 71d shown in FIG. 9 are connected to a connecting shaft 47 arranged in a substantially square shape in plan view via a rotation base 55, an output shaft, and a surgical element base 70, respectively. It is arrange | positioned in the position which makes four vertices of a substantially square by the bottom view shown. Among them, the surgical elements 71a and 71b that rotate counterclockwise adjacent to each other in the front-rear direction rotate the centers P1 and P2 of the surgical element base portions 72 with a phase shift of 180 degrees from each other about the connecting shaft 47. To do.

  Similarly, in the surgical elements 71c and 71d that rotate clockwise, the centers P3 and P4 of the surgical element base portions 72 rotate around the connecting shafts 47 with a phase shift of 180 degrees. Further, in the treatment elements 71a and 71c (treatment elements 71b and 71d) adjacent in the left-right direction, the centers P1 and P3 (centers P2 and P4) of the treatment element base portions 72 are in relation to the vertical bisector L. Rotate to be line-symmetric with each other.

  According to such a configuration, the states P1 and P3 of the treatment elements 71a and 71c and the centers P2 and P4 of the treatment elements 71b and 71d are farthest in the front-rear direction (90 degrees in the reverse direction from the state of FIG. 9). When the surgical elements 71a to 71d are each rotated 90 degrees from the rotated state, as shown in FIG. 9, the surgical elements 71a and 71c are brought into the closest state in the left-right direction.

As a result, the surgical elements 71a and 71c operate so as to be pinched between the surgical protrusions 73. At this time, the scalp sandwiched between the surgical elements 71a and 71c is moved in the rotation direction.
Further, when the surgical elements 71a to 71d are rotated 90 degrees, in the surgical elements 71a and 71b rotating in the same direction, the centers P1 and P2 of the surgical element base portions 72 are closest to each other at the same timing.

  When the space between the surgical elements 71a and 71b is viewed locally, the surgical elements 71a and 71b rotate around each other so as to pass each other. As a result, the scalp is sandwiched between the surgical elements 71a and 71b approaching at the same timing, and a twisting motion can be imparted to the scalp by passing each other.

  Then, when the surgical elements 71a and 71b that perform the pinching operation and the twisting operation are brought into contact with the scalp, the scalp of the user is effectively moved according to the movement of the surgical elements 71a and 71b. As a result, the scalp is cared for (massaged). In addition, in the surgical elements 71c and 71d, the same pinching and twisting motion as the surgical elements 71a and 71b is performed.

  As described above, in the example shown in FIG. 9, different types of movements can be given to the scalp according to the rotation angles of the surgical elements 71a to 71d (centers P1 to P4). It can contribute to improvement.

  Further, as described above, the operation of moving the user's scalp in one direction in the front-rear direction (direction from the upper side to the lower side in FIG. 9) between the surgical elements 71a and 71c and between the surgical elements 71b and 71d. Is implemented. And the arch part 14 is extended in the direction orthogonal to this operation direction X with directionality in planar view. For this reason, the arch part 14 functions as a recognition means for recognizing the operation direction X of the scalp care device 10 from the extending direction.

  As shown in FIG. 4, the arch portion 14 is formed so as to form a substantially annular shape with the portion of the upper surface 11 b of the apparatus main body portion 11, and is used in the finger insertion hole 16 surrounded by the substantially annular portion. The person inserts three or four fingers other than the thumb from the finger insertion direction ID, and grips the upper surface of the apparatus main body 11 with the palm placed on the gripping surface 15. At this time, the longitudinal direction fingertip side of the three or four fingers inserted into the finger insertion hole 16 can be made to substantially coincide with the movement direction X.

  Further, on the upper surface 11 b (that is, the gripping surface 15) of the apparatus main body 11, the curvature of the surface on the inlet side in the finger insertion direction ID with respect to the upper surface central portion 15 a is larger than the surface on the portion on the outlet side in the finger insertion direction ID. Increased curvature.

  In other words, the curvature of the surface on the downstream side of the operation direction X is made larger than the curvature of the surface of the upper surface 11b of the apparatus main body 11 on the upstream side in the operation direction X with respect to the upper surface central portion 15a.

  For this reason, when the apparatus main body 11 is gripped by inserting three or four fingers from the wrong finger insertion direction (counter-ID direction), it is possible to give a discomfort due to the difference in curvature of the gripping surface 15 to the palm. . As a result, the user can recognize from the discomfort of the palm that the finger insertion direction is wrong, reinsert the finger from the appropriate finger insertion direction ID, and can grip the scalp care device 10 in the appropriate gripping direction.

  In addition, by lowering the height of the rear upper end 13h than the front upper end 13g of the apparatus main body 11, the palm of the hand when gripping in the wrong finger insertion direction as compared with gripping with an appropriate finger insertion direction ID is achieved. The feeling of discomfort given to can be made clearer.

  In this way, by making a difference in the height relationship between the upper end portions 13g and 13h, the user can change the direction of the directional movement of the surgical elements 71a to 71d (the movement direction X) by the user's palm placed on the gripping surface 15. Can be recognized from the sense of discomfort. Therefore, when the user grips the apparatus main body 11, the gripping direction can be limited to one direction, and the scalp care device 10 can be gripped in the gripping direction that matches the operation direction X.

  Further, when the scalp care device 10 is viewed from a direction parallel to the operation direction X, the inner peripheral surface of the portion where the arch portion 14 extends upward from the side end portion 13i serving as the root portion once spreads outward. It has a shape that narrows inward.

  That is, the curvature change point Pv, which is a place where the arch portion 14 changes from the widened portion to the narrowed portion, is arranged at a higher position than the side end portion 13 i that becomes the root portion of the arch portion 14. For this reason, two fingers (an index finger and a ring finger or a little finger) positioned at both ends of the plurality of fingers inserted into the finger insertion hole 16 can be accommodated in the finger insertion hole 16 without being cramped. The upper surface of the apparatus main body 11 can be firmly grasped by using the finger effectively.

  If the inner peripheral surface of the arch part extends from the root part in a shape that narrows inward in the width direction, the area where the finger cannot be placed because the width in the vertical direction is narrowed at the corners at both ends in the width direction of the finger insertion hole 16 Will occur.

  In this case, the outer side surface or a slightly upper portion of the two fingers on both ends inserted into the finger insertion hole 16 hits the inner peripheral surface of the arch part and feels tightness. However, in this embodiment, since the curvature change point Pv is arranged at a position higher than the side end portion 13i, the two fingers inserted into the arch portion 14 are connected to the corners at both end portions in the width direction of the finger insertion hole 16. The upper surface of the apparatus main body 11 can be gripped by effectively using the finger insertion holes 16 in the width direction.

  Further, the side end portion 13 i that becomes the root portion of the arch portion 14 is set at a position higher than the central portion 15 a in the width direction on the upper surface 11 b facing the arch portion 14. Therefore, the gripping surface 15 matches the palm shape when gripping.

  As shown in FIGS. 1 and 3 to 5, the panel member 17 is provided with a protrusion 17 a at the end of the panel member 17 on the entrance side in the finger insertion direction ID. The panel member 17 can be removed from the main body housing 13 by performing an operation of pushing the protrusion 17 a with a finger to remove the hook that holds the panel member 17 to the main body housing 13.

  For example, when the protrusion 17a is at the end of the panel member 17 on the outlet side in the finger insertion direction ID, the user is holding the device main body 11 while using the scalp care device 10 and is around the first joint of the finger. The protrusion 17a is located at the position.

  In this case, when the user applies force to the finger to firmly hold the scalp care device 10, the projection 17a is pushed to the near side (in the unlocking direction), and the panel member 17 may be unintentionally detached. There is.

  However, in the preferred configuration of the present embodiment, the protrusion 17a is disposed at the end of the panel member 17 on the entrance side in the finger insertion direction ID, so that the palm center when the user holds the scalp care device 10 is used. The protrusion 17a is positioned around the depression.

  For this reason, it is avoided that the protrusion 17a is pushed into the palm until the locking is released, as well as the finger force that the user has tried to hold the scalp care device 10 firmly. Therefore, it is possible to avoid a situation in which the hook of the panel member 17 is released due to the gripping force during the care using the scalp care device 10.

Moreover, since the protrusion 17a is located near the dent in the center of the palm (slightly closer to the wrist), even if the protrusion 17a is on the surface gripped by the user, there is no sense of incongruity.
Next, characteristic effects of the present embodiment will be described.

  (1) The surgical elements 71a to 71d perform the operation in the directional operating direction X based on the drive of the motor 32. The scalp care device 10 includes the operating directions X of the surgical elements 71a to 71d. The arch part 14 having a recognition function capable of recognizing the above is provided.

  The arch part 14 extends across the direction intersecting the operation direction X on the side opposite to the side where the treatment elements 71 a to 71 d of the apparatus main body part 11 are provided. Thereby, the user can recognize the operation direction X of the surgical elements 71a to 71d by the extending direction of the arch portion 14. For this reason, the user can hold the scalp care device 10 in an appropriate holding direction corresponding to the operation direction X.

  (2) In the gripping surface 15 which is the upper surface of the apparatus main body 11, the curvature of the surface of the entrance side portion in the finger insertion direction ID is higher than that of the upper surface center portion 15a, and the exit side portion of the finger insertion direction ID is higher than the upper surface center portion 15a. It was larger than the curvature of the surface.

  That is, in the gripping surface 15, the curvature of the surface on the upstream side in the operation direction X with respect to the upper surface central portion 15a is larger than the curvature of the surface on the downstream side in the operation direction X with respect to the upper surface central portion 15a. did.

  For this reason, when the finger is inserted in an appropriate finger insertion direction ID and the scalp care device 10 is gripped, the gripping surface 15 fits the palm. If the scalp care device 10 is grasped by inserting a finger from an inappropriate finger insertion direction ID, the finger placed on the grasping surface 15 and the palm can be given a sense of incongruity due to a difference in curvature. As a result, the user can grasp the scalp care device 10 again by an appropriate grasping method.

  Further, the grip surface 15 has a larger curvature on the surface of the portion on which the finger is placed than on the surface of the portion on which the palm is placed, so that the second joint of the finger placed on the grip surface 15 has a relatively large angle. The scalp care device 10 can be gripped more firmly by bending. Furthermore, since the gripping surface 15 has a convex arc shape, a relatively wide space is secured on the front side of the finger insertion hole 16 when a finger is inserted into the arch portion 14, and the ease of inserting the finger is ensured. .

  (3) Since the height of the rear upper end portion 13h of the apparatus main body 11 is set lower than the front upper end portion 13g, it is easy to insert a finger into the arch portion 14 and an appropriate finger insertion direction ID. When the hand is inserted and gripped, the palm fits the gripping surface 15.

  In addition, when the user inserts a finger in an inappropriate finger insertion direction and holds the scalp care device 10, it is possible to give a discomfort to the palm. As a result, the user can grasp the scalp care device 10 again by an appropriate grasping method.

  (4) A convex shape is formed on the center line of the gripping surface 15 extending from the upper surface central portion 15a to the front upper end portion 13g, so that the finger naturally wraps the gripping surface 15 when gripped by the user's finger. Is possible. Thereby, the operation direction X of the treatment elements 71a to 71d can be recognized more easily.

  (5) Since the central portion 15b in the width direction on the upper surface 11b of the apparatus main body 11 is configured in a concave arc shape, the opening in the central portion in the width direction of the finger insertion hole 16 formed between the arch portion 14 and the upper surface 11b. A wide space can be secured in the vertical direction, and insertion of fingers during gripping can be facilitated.

  (6) When the scalp care device 10 is viewed from the operation direction X in the front view and the back view, the shape of the upper surface 11b of the device main body 11 facing the arch portion 14 is positioned so that the central portion 15a is lower than the side end portion 13i. Constructed in a concave arc shape. For this reason, the gripping surface 15 can be matched more with the shape of the palm at the time of gripping, and a better usability can be given to the user.

  (7) On the inner peripheral surface near the base of the arch part 14, the curvature change point Pv, which is a part that has changed from a part that spreads upward from the side end part 13i that is the base part to a part that has stopped spreading, It arrange | positions in the position higher than the side edge part 13i.

  For this reason, a wide space in the width direction in which the fingers at both ends inserted into the finger insertion holes 16 can be arranged can be secured. For example, when the arch part has an inner peripheral surface shape whose width is narrower at the upper part from the root part, the space where the fingers at both ends can be arranged becomes narrow in the width direction, and the fingers at both ends feel tight. However, in this embodiment, since the inner peripheral surface of the arch part 14 located on the side of the fingers on both ends is a concave curved surface along the curved surface of the finger, the fingers on both ends are on the inner periphery of the arch part 14. Even if it hits the surface, it does not feel cramped.

In addition, you may change embodiment as follows.
-In the said embodiment, an arch part is formed in each area | region which divided | segmented the formation area of the arch part into a plurality, and a plurality (2-4 pieces) of arch parts are provided, and one finger is provided for each arch part. It may be configured to hold the gripping portion (grip surface) of the apparatus main body.

  Of course, a plurality of fingers may be put in at least one of the plurality of arch portions. For example, two fingers and one finger may be put in separate arch portions, or two fingers may be put in two arch portions, or a combination of three and one finger.

  -In the said embodiment, the structure which arrange | positions the axis line of the connection shaft 47 and the centers P1-P4 of operation element 71a-71d coaxially, and the operation elements 71a-71d rotate centering on P1-P4 may be sufficient. In this case, since the treatment elements 71a to 71d do not rotate eccentrically, it is desirable that the treatment elements 71a to 71d and the cover portion 61 are separate.

  In the above-described embodiment, in addition to the operation elements 71 a to 71 d operating in the operation direction X orthogonal to the output shaft 56, a configuration is adopted in which the operation elements 71 a to 71 d are operated in an axial direction parallel to the output shaft 56. Also good. According to this configuration, it is possible to give a stimulus that strikes the user's scalp. Further, the treatment element may operate so as to wave in the operation direction X. In this case, the treatment element may be rotated, or may be only a undulating motion without rotation.

  -In above-mentioned embodiment, you may employ | adopt the structure which made the cover part 61 and the treatment element 71a-71d which comprise the treatment head part 12 into a different body. However, the treatment protrusions 73 of the treatment elements 71a to 71d are preferably constituted by a flexible member (elastic member) in any configuration.

  In the above embodiment, four surgical elements 71a to 71d are provided, but the number may be arbitrarily changed. Moreover, although it was set as the structure which provided the four treatment protrusions 73 which comprise the treatment element 71a-71d, respectively, the number may change arbitrarily, for example, the number of the treatment protrusion 73 differs in each treatment element 71a-71d. May be.

  Furthermore, although it was set as the structure which provided three small diameter protrusions 73a at the front-end | tip of each treatment protrusion 73, the number may be changed arbitrarily, for example, in each treatment protrusion 73, the number of protrusions 73a may differ. Further, a configuration in which the protrusion 73a is omitted may be employed.

  -The arch part may be divided | segmented by one slit in the middle of the extension direction. For example, the central part of the arch part in the extending direction may be divided by a slit, and the arch part may be configured by a pair of cantilevered arm parts that form a half of the arch part.

  The arch portion is not limited to the configuration integrally formed with the main body housing 13, and may be a separate member from the main body housing 13. The base portion of the arch member is fixed to a side surface or upper surface side end portion of the main body housing 13 by a known fixing method such as screwing, bonding, or locking.

  The number of arch portions is not limited to one, and a plurality of arch portions such as two or three may be arranged in the apparatus main body portion in a direction intersecting the extending direction. In this case, the number of fingers inserted into each of the plurality of arch portions may be the same or different.

  If the number of fingers inserted into each arch part is different, the number of fingers inserted into the arch part on the entrance side in the finger insertion direction is determined from the viewpoint of ease of finger insertion and recognition of the movement direction X. It is desirable that the number of fingers inserted into the exit-side arch portion is larger than the number of fingers. Moreover, it is desirable that the opening area of the finger insertion hole formed by the entrance-side arch portion in the finger insertion direction is larger than the opening area of the finger insertion hole formed by the exit-side arch portion.

  -The width | variety in the extension direction center part of an arch part may be formed wider than the width | variety by the side of a root part. With this configuration, the back of the hand that grips the main body is supported by the wide portion of the arch, so that a sense of stability can be obtained when the main body is gripped. Of course, conversely, the central portion of the arch portion in the extending direction may be narrow and the base portion side may be wide.

  As described above, the scalp care device according to the present invention makes it possible for the user to easily recognize the proper way of holding the device itself, so that it is not limited to the scalp, but the face, neck, shoulders, back. It can also be applied to uses such as instruments intended to care for at least part of the body, such as care for the abdomen, buttocks, arms, and legs.
