Specifically, in the vibration generating structure of the present embodiment, the rotary blade shaft 17 also serves as the vibration generating shaft 51 and is arranged in parallel with the central axis P2 of the razor head 2. The eccentric weight 52 is externally fitted and fixed to the rotary blade shaft 17 protruding upward from the tip support frame 23 of the support frame 22. When the motor 3 is activated, the eccentric weight 52 is rotationally driven together with the movable blade 15, and vibrations following the horizontal plane (following the plane orthogonal to the excitation shaft 51) are generated. Due to the generated vibration, the fixed blade 14 held in an arch shape vibrates in the thickness direction on the entire circumference thereof. At this time, since the rotary blade shaft 17 is arranged behind the central axis P2 of the razor head 2, vibration is more easily transmitted to the short hair cutting portion 10 side. As described above, when the excitation shaft 51 is arranged to be parallel to the central axis P2 of the razor head 2, that is, to generate vibration including a vibration component for causing the fixed blade 14 to vibrate in the thickness direction, it is easily applied to the skin surface. The fixed blade 14 can be vibrated in the thickness direction at the top of the peripheral surface portion of the fixed blade 14 often used in the main. Therefore, the fixed blade 14 is vibrated in a direction orthogonal to the skin surface, and intermittently. Since the fixed blade 14 can be pressed against the skin surface, the whiskers can be introduced deeper into the inner side of the fixed blade 14 and deep shaving can be performed in the finish shaving. Further, since the rotary blade shaft 17 of the movable blade 15 also serves as the vibration generating shaft 51, it is not necessary to provide a motor dedicated to the vibration generating structure, and the structure of the electric shaver is simplified and the vibration generating structure is provided. Increase in cost of electric razor can be suppressed. Since the motor 3 is provided in the main body case 1, the razor head 2 can be downsized and the structure thereof can be simplified.

As described above, when a vibration generating structure for vibrating the razor head 2 is provided inside the head case 9, the movable blade 15 of the short hair cutting unit 10 is vibrated by the vibration generated by the vibration generating structure. The sharpness can be improved and the whiskers can be cut efficiently. Further, by providing a vibration generating structure on the front end side of the head case 9 away from the main body case 1 that also serves as a grip, it is possible to minimize the transmission of vibrations generated by the vibration generating structure to the fingers that grip the electric razor. .
According to the vibration generating structure provided with the support frame 22, the vibration generated in the vibration generating structure can be efficiently transmitted to the movable blade 15, so that the sharpness of the movable blade 15 can be further improved. In addition, since the contact pressure between the movable blade 15 and the fixed blade 14 is changed by vibration, the sliding resistance of the movable blade 15 made of a rotary blade can be reduced, and the load on the motor 3 is reduced and the power consumption is suppressed. Can be achieved.

  As shown in FIG. 4, the long hair cutting portion 37 where the razor blade 38 is disposed faces the connecting frame 24 with the head case 9 on the side of the inner circumferential surface 9 b of the head case 9 in between. Further, the inner surface side of the inner biased peripheral surface 9b and the front surface of the connecting frame 24 are arranged so as to contact each other. Thus, when the long hair cutting part 37 and the connection frame 24 are arranged, the vibration generated by the vibration generating structure can be applied to the razor blade 38 via the connection frame 24 and the head case 9. The sharpness can be improved, and long hairs and comb hairs can be cut more efficiently. Note that the inner surface side of the inner biased peripheral surface 9b and the front surface of the connecting frame 24 are not necessarily in contact with each other, and may be arranged with a slight gap.

  As shown in FIG. 3, an illuminating body 55 that illuminates the razor head 2 is provided at the upper end of the front portion of the main body case 1 facing the virtual space S. The illuminating body 55 is constituted by a bullet-type LED, and its optical axis is directed toward the long hair cutting portion 37. A diffusion block 56 is disposed at the tip of the illuminating body 55 so that light emitted from the illuminating body 55 is diffused. When using an electric razor, the beard can be cut while illuminating the razor head 2, the long hair cutting portion 37 and the skin surface with the illumination light emitted from the illuminating body 55, so that the state of the beard and the beard cutting state can be accurately grasped The whisker can be cut accurately while being.

  When using an electric razor, first, the front end surface 9c of the head case 9 is applied to the skin surface, and the long hair or the comb hair that has fallen into the skin surface is raised by the skin contact body 48 so as to be easily cut. Next, the long hair and the comb hair are roughly shaved by the long hair cutting portion 37 in which the razor blade 38 is disposed, and further the final hair shaving is performed by the short hair cutting portion 10. In this manner, a series of shaving operations such as raising, rough shaving, and finishing shaving can be efficiently performed with only one electric razor.

Example 2 FIGS. 5 and 6 show Example 2 of an electric shaver according to the present invention. In this embodiment, as shown in FIG. 5, a hair raising body 59 made of a group of protrusions (unevenness) that can apply pressure to the skin surface in a point manner is formed along the skin protection portion 44. The hair raising body 59 functions as a part of the skin protection unit 44 and increases the chance of contact between the skin protection unit 44 and the skin surface. Further, as shown in FIG. 6, each mounting portion 40 of the razor blade 38 is bonded and fixed to the mounting slit 41 in a state where the cutting blade 39 faces the top of the brushed body 59. A large number of protective wires 60 are arranged at equal intervals on the outer surface of the razor blade 38 so as to intersect with the cutting blade 39 of the razor blade 38, and both end portions thereof are embedded and fixed in the head case 9. Since the left and right ends of the protection wire 60 in this state are held so as not to move up and down by the vertically raised hairs 59, when the razor blade 38 is in contact with the skin surface, the protection wire 60 is against the cutting edge 39. Can be prevented from moving up and down. Since others are the same as those of the first embodiment, the same members are denoted by the same reference numerals and the description thereof is omitted. The same applies to the following description.

As described above, when the hair raising body 59 is formed on the skin protecting portion 44, the hair that has fallen into the long hair or the skin surface is caused by the hair raising body 59, and the chance of contact with the razor blade 38 is increased. Cutting can be performed more efficiently.
When the protective wire 60 is provided on the outer surface of the razor blade 38, the protective wire 60 can prevent the cutting blade 39 from being unnecessarily pressed against the skin surface, so that the skin of the razor blade 38 can be softened. The damage that the blade 38 gives to the skin surface can be reduced.
When the protective wire 60 is held immovably by the hair raising body 59, it is not necessary to provide a separate member for holding the protective wire 60, and the razor blade 38 is prevented from moving out of the skin with a simple configuration. Damage to the can be reduced.

(Example 3) FIG. 7 shows Example 3 of an electric shaver according to the present invention. In the present embodiment, a long hair cutting portion 37 composed of a razor blade 38 is provided on the outer peripheral surface of the head case 9 in a state adjacent to the short hair cutting portion 10. As described above, when the short hair cutting part 10 and the razor blade 38 are adjacent to each other, the shaver blade 38 and the short hair cutting part 10 are applied to the skin surface and shaved by simply twisting the wrist without having to change the electric razor. Since the finish shave can be performed, effective beard cutting can be performed in a short time. Moreover, since the short hair cutting | disconnection part 10 does not turn downward when using the razor blade 38, it can prevent that the shavings cut | disconnected by the short hair cutting | disconnection part 10 fall down.

(Example 4) FIG. 8 shows Example 4 of an electric shaver according to the present invention. In the present embodiment, a plurality of rib-like protrusions 62 that are long in the axial direction of the head case 9 (razor head 2) are formed on the inner biasing peripheral surface 9b (outer peripheral surface) of the head case 9 facing the short hair cutting portion 10. A skin contact body 48 is provided, and a long hair cutting portion 37 including a single razor blade 38 is provided on the distal end surface 9 c of the head case 9. The head case 9 includes a cylindrical case 63 and a tip piece 64 that is externally fitted to the tip of the cylindrical case 63. The razor blade 38 is attached to the mounting portion 40 so that the cutting edge 39 is along the left-right direction. It is bonded and fixed to the slit 41. The skin protection portion 44 facing the cutting edge 39 of the razor blade 38 is configured by a rib-like protrusion that is formed to protrude from the tip end surface 9 c of the head case 9, and the cutting blade 39 of the razor blade 38 has the skin protection portion 44. It is provided so as to face the top. The razor blade 38 of this embodiment is exchanged with the tip piece 64 of the head case 9. The rib-like protrusions 62 may be provided with a plurality of thin fin-like bodies close to each other. In this case, the fin-like body exhibits elasticity and flexibility, so that silicon rubber or nitrile rubber is used. It is preferable to form with a flexible rubber material such as. A protrusion group (uneven protrusion group) 49 can be provided on the outer peripheral surface of the head case 9 instead of or in combination with the rib-shaped protrusion 62.

  The excitation structure includes an excitation motor 65 dedicated to the excitation structure and an eccentric weight 52 fixed to the output shaft of the excitation motor 65, and the output shaft of the excitation motor 65 also serves as the excitation shaft 51. ing. The output shaft of the vibration motor 65 is disposed parallel to the central axis P2 of the razor head 2 orthogonal to the virtual reference line Q, and is mounted on a motor fixing seat 66 provided on the inner surface of the front upper portion of the cylindrical case 63. Yes. In this state, the lower end surface of the vibration motor 65 is in close contact with the upper surface of the tip support frame 23. Thereby, the vibration generated by the vibration generating structure is transmitted to the head case 9 and the support frame 22. As described above, when the excitation shaft 51 is arranged to be parallel to the central axis P2 of the razor head 2, that is, to generate vibration including a vibration component for causing the fixed blade 14 to vibrate in the thickness direction, it is easily applied to the skin surface. The fixed blade 14 can be vibrated in the thickness direction at the top of the peripheral surface portion of the fixed blade 14 often used in the main. Therefore, the fixed blade 14 can be vibrated in a direction orthogonal to the skin surface. Thereby, since the fixed blade 14 can be intermittently pressed against the skin surface, the whiskers can be introduced deeper into the inside of the fixed blade 14 to deepen in the finish shaving. Moreover, since the vibration motor 65 is disposed in front of the central axis P2 of the razor head 2, vibration is more easily transmitted to the skin contact body 48 side. Accordingly, the vibration generated by the vibration generating structure can be efficiently applied to the skin contact body 48, and the long hair and the shampoo that has fallen into the skin surface can be caused more quickly. In addition, according to the vibration generating structure provided with the vibration generating motor 65, there is an advantage that the degree of freedom of the arrangement position of the vibration generating structure can be improved and the vibration applying direction can be freely set. As in the first embodiment, since the fixed blade 14 is held in an arch shape in this embodiment, the fixed blade 14 is caused to generate vibration regardless of the orientation of the excitation shaft 51. A vibration component for vibrating in the thickness direction is included. In each of the above-described embodiments, the skin contact body 48 including the plurality of rib-like protrusions 62 is not provided. However, such a skin contact body structure is naturally provided on the outer peripheral surface of the case 9 with another functional structure. For example, the long hair cutting part 37 for cutting long hairs and comb hairs, or a fleece discharge structure described later can be used in combination. The same applies to the skin contact body structures of the following examples.

  The vibration motor 65 is rotated 90 degrees around the virtual reference line Q from the state of the present embodiment so that the output shaft (vibration shaft 51) of the vibration motor 65 is orthogonal to the central axis P2 of the razor head 2, for example. It can be arranged in the state. In this case, the razor head 2 can be vibrated in the direction of the central axis P2 while vibrating the fixed blade 14 in the thickness direction at the top of the peripheral surface portion of the fixed blade 14. Accordingly, the beard can be cut off by the movable blade 15 and the razor blade 38 while intermittently pressing the fixed blade 14 against the skin surface, so that the sharpness of both the blades 15 and 38 can be improved. It should be noted that the excitation shaft 51 is not only in a state orthogonal to the central axis P2 of the razor head 2 as described above, but also has a thickness at the top of the fixed blade 14 no matter where it is rotated around the virtual reference line Q. Can vibrate in the direction.

  The vibration motor 65 in this embodiment can be arranged by forming a motor fixing seat 66 on the rear side of the top of the cylindrical case 63. In this case, since the vibration motor 65 is disposed in the vicinity of the fixed blade 14, vibration can be effectively applied to the fixed blade 14. At this time, if the output shaft of the vibration motor 65 is set in the same direction as the central axis P2 of the razor head 2, vibrations can be applied in the thickness direction on all surfaces in the circumferential direction of the fixed blade 14, so that the depthing is effective. Can be done automatically. The vibration motor 65 can also be fixed to a fixed seat provided on the support frame 22. In this case, the vibration generating structure can effectively vibrate the top portion of the fixed blade 14 in the thickness direction via the movable blade 15, making it easier to transmit the vibration by the fixed blade 14, and further reducing the cutting effect. Can be increased. In the present invention, “the support frame 22 is provided with the vibration generating structure” means that the vibration generating structure is assembled to the support frame 22 as in the first embodiment, or as in the present embodiment. This means that the vibration motor 65 is fixed to a part other than the support frame 22 and a part thereof is in contact with the support frame 22.

Example 5 FIGS. 9 and 10 show Example 5 of an electric shaver according to the present invention. In this embodiment, as shown in FIG. 9, two flat razor blades 38 are provided on the front end surface 9c of the head case 9, and the opposite edge of the cutting edge 39 is inclined with respect to the front end surface 9c. The attachment portion 40 is attached to the attachment slit 41 to form a long hair cutting portion 37. As shown in FIG. 10, the cutting blades 39 of the razor blade 38 attached to the attachment slit 41 are arranged so as to face the left and right skin protection portions 44, respectively.

  If the razor blade 38 is provided on the tip surface 9c of the razor head 2 as in the fourth and fifth embodiments, the tip surface 9c of the razor head 2 can be easily moved and operated with respect to the skin surface. Long hairs and comb hairs can be cut accurately. Further, since the razor blade 38 can be finely operated, long hairs and comb hairs in a narrow region can be accurately cut.

Example 6 FIGS. 11 to 13 show Example 6 of an electric shaver according to the present invention. In this embodiment, as shown in FIG. 11, the functional structure is composed of a skin contact body 48 including a hair raising bar 69, and an L-shaped support arm 70 is provided at the upper end (one end) of the hair raising bar 69. It is provided integrally. The front end surface 9c of the head case 9 is formed in a horizontal plane, and the hair raising rod 69 is supported by the arm support hole 71 of the head case 9 so that the middle portion of the vertical shaft portion of the support arm 70 can rotate. The periphery of the case 9 can be rotated. The hair raising rod 69 is opposed to the outer peripheral surface of the head case 9 through a gap at any position around the head case 9, and at least the hair raising rod 69 faces the long hair cutting portion 37 in the virtual space S. In the state of being located inside, the hair raising rod 69 is housed inside the outer shape of the cross section of the main body case 1. Further, the facing gap E1 between both the hair raising rod 69 and the razor blade 38 in a state where the hair raising rod 69 and the razor blade 38 are opposed to each other is such that the hair raising rod 69 and the short hair cutting portion 10 are opposed to each other. It is set smaller than the facing gap E2. As shown in FIG. 12, the hair raising rod 69 has a bristle composed of three rib-like protrusions 62 formed long in the axial direction of the hair raising rod 69 except for the circumferential surface facing the outer circumferential surface of the head case 9. A raising body 59 is provided.

  A moderation structure is provided between the head case 9 and the support arm 70 to hold the hair raising rod 69 in a predetermined position, and the hair raising rod 69 faces the razor blade 38 and the short hair cutting portion 10. It is comprised so that position can be hold | maintained in the state which opposes. As shown in FIG. 13, the moderation structure has a moderation recess 72 provided on the head case 9 side, a moderation projection 73 provided on the support arm 70 side, and the moderation recess 72 and the moderation projection 73 held in an engaged state. A force spring 74 and the like are provided. A support boss 75 is provided on the inner surface of the front end of the head case 9, and a moderation recess 72 is formed in the front and rear of the lower surface side of the boss 75. In addition, an arm support hole 71 that rotatably supports the vertical shaft portion of the support arm 70 is formed in the center of the support boss 75. A flange body 76 that is fixed in a non-rotatable manner is provided in the middle portion of the vertical shaft portion of the support arm 70, and a moderation protrusion 73 projects from the upper front side of the flange body 76. The moderation structure is covered with a bottomed cylindrical cover body 77 fitted and fixed to the support boss 75, and a biasing spring 74 is disposed between the flange body 76 and the bottom wall inner surface of the cover body 77. . The lower end of the vertical shaft portion of the support arm 70 is also rotatably supported by the bottom wall of the cover body 77.

  The hair raising bar 69 held in a position facing the long hair cutting portion 37 with a moderation structure pushes the support arm 70 downward, whereby the engagement state of the front moderation recess 72 and the moderation projection 73 is released and the rotation bar 69 is rotated. It becomes movable. In this state, by rotating to the short hair cutting part 10 side and releasing the pushing of the support arm 70, the moderation protrusion 73 is engaged with the moderation recess 72 on the rear side, and the hair raising rod 69 cuts the short hair. The position is held at a position facing the portion 10. When the hair raising rod 69 is held again on the long hair cutting portion 37 side, the support arm 70 is pushed downward to disengage the moderation recess 72 and the moderation projection 73 on the rear side, and the moderation projection 73 is moved to the front side. The moderation recess 72 may be engaged. In this way, the holding position of the hair raising bar 69 can be changed by pushing the support arm 70 and rotating it. In FIG. 13, reference numeral 78 denotes a restriction flange that defines the pushing limit of the support arm 70. Also in this embodiment, since the razor head 2 is provided with the skin contact body 48, the long hair cutting portion 37, and the short hair cutting portion 10, a series of shaving operations such as hair raising, rough shaving, and finishing shaving are performed with one electric shaving operation. Efficiently using only a razor.

  As described above, when the hair raising rod 69 is opposed to the outer peripheral surface of the head case 9 via a gap, the hair raising rod 69 is brought into contact with the skin surface before the head case 9 to accurately cause long hairs and hairs. Can do. Further, when the hair raising body 59 composed of the rib-like protrusions 62 is formed on the hair raising bar 69, it is possible to increase the chances of contact between the hair raising bar 69 and the skin surface and to raise long hairs and hairs more accurately.

  When the hair raising rod 69 can rotate around the head case 9, the posture of the electric shaver is greatly changed by positioning the hair raising rod 69 in the vicinity of the short hair cutting portion 10 or the long hair cutting portion 37. In addition, the hair raising by the hair raising rod 69 and the hair cutting by the short hair cutting part 10 or the long hair cutting part 37 can be performed. Further, by positioning the hair raising rod 69 far from the short hair cutting portion 10 or the long hair cutting portion 37, the hair raising by the hair raising rod 69 and the hair cutting by the short hair cutting portion 10 or the long hair cutting portion 37 are used properly. be able to. Therefore, since the use form can be selected alternatively depending on the position of the hair raising bar 69, the electric razor can be used in the use form preferred by the user. For example, in a state where the hair raising rod 69 is directly opposed to the short hair cutting portion 10, the movable blade 15 (motor 3) is driven to actively use the hair raising rod 69 and the short hair cutting portion 10. be able to. In this case, whiskers can be cut by the short hair cutting portion 10 while raising the beard with the hair raising rod 69. Therefore, the beard can be effectively cut. At this time, the moderation structure is set so that the hair raising rod 69 can be held in any position in the circumferential direction of the fixed blade 14 (for example, the central portion and the three end portions of the stationary blade in the circumferential direction). Then, the hair raising rod 69 will not rotate carelessly.

In the state where the hair raising bar 69 is located in the virtual space S, when the hair raising bar 69 is within the outer shape of the cross section of the main body case 1, the electric razor is placed on the mounting table in a lying posture. In this state, the hair raising rod 69 can be prevented from coming into contact with the placement surface, so that the hair raising rod 69 can be prevented from being damaged due to contact with or collision with the placement surface.
The opposing gap E1 between both the hairs 38 and 69 in a state where the brushing bar 69 and the razor blade 38 are opposed to each other, and the opposing gap between the both hairs 10 and 69 in a state where the hair raising bar 69 and the short hair cutting portion 10 are opposed to each other. If it is set to be smaller than E2, the razor blade 38 can be more reliably protected by the raising bar 69. Further, in a state where the hair raising bar 69 is directly opposed to the short hair cutting part 10, there is no possibility that the long hair and the comb hair are captured by the short hair cutting part 10 and the beard is pulled when the electric razor is not driven. .

  When the moderation structure is provided so that the hair raising rod 69 can be held in a position facing the long hair cutting portion 37 composed of the short hair cutting portion 10 or the razor blade 38, the razor blade 38 is used during use of the short hair cutting portion 10. Since it can be covered with the hair raising rod 69, it is possible to prevent the skin surface from being accidentally damaged by the razor blade 38 of the long hair cutting portion 37. Moreover, since the short hair cutting part 10 can be covered with the hair raising stick 69 during use of the long hair cutting part 37, it can prevent that clothes etc. are caught in the short hair cutting part 10 accidentally.

Example 7 FIGS. 14 to 16 show Example 7 of an electric shaver according to the present invention. In the present embodiment, as shown in FIG. 14, the fluff discharge structure that facilitates the discharge of the fluff retained in the fluff chamber R on the inner peripheral surface 9 b of the head case 9 facing the virtual space S. (Functional structure) was provided. Specifically, a discharge window (window) 80 communicating with the fuzz chamber R inside the razor head 2 is opened on the peripheral wall of the head case 9 so that the discharge window 80 can be opened and closed by the opening / closing body 81. The functional structure was configured. The opening / closing body 81 includes a shutter 82 that slides the discharge window 80 up and down, that is, in the direction of the central axis P2 of the razor head 2. As shown in FIG. 15, the shutter 82 is formed in an outwardly curved shape along the peripheral surface of the head case, and an operation piece 83 for hooking a finger when the shutter 82 is opened and closed is provided on the outer surface of the lower end. ing. A pair of L-shaped guide pieces 84 are provided on the left and right edges of the shutter 82, and the guide pieces 84 are formed by a head case 9 and a square frame-like shutter frame 85 fixed to the case 9. The guide groove 86 is slidably guided. Although not shown, the shutter 82 includes a holding structure that is held in an open position and a closed position. A discharge opening 87 is formed in the connecting frame 24 of the support frame 22 that faces the discharge window 80, so that the hair and cleaning water in the hair chamber R can be efficiently discharged from the discharge window 80. In the present embodiment, the long hair cutting portion 37 composed of one razor blade 38 is provided on the tip surface 9 c of the head case 9. In addition, although each of the above-described embodiments is not provided with the fluff discharge structure including the discharge window 80 and the opening / closing body 81, such a foul discharge structure is naturally provided on the outer peripheral surface of the case 9 with another functional structure. For example, it can be configured in combination with the long hair cutting portion 37 for cutting long hairs and comb hairs or the rib-like protrusions 62 having a hair raising function. The same is true for the fluff discharging structure of the following embodiments.

  When cleaning the inside of the fuzz chamber R, the shutter 82 is opened as shown in FIG. 16, and the position of the electric razor is held in a state where the discharge window 80 faces downward. In this state, cleaning water is supplied from the short hair cutting unit 10 to the fuzz chamber R, and the fouling chamber R is cleaned by discharging the fouling together with the cleaning water through the discharge opening 87 and the discharge window 80. At this time, by starting the motor 3, the hair chamber R can be cleaned more effectively by stirring the cleaning water in the hair chamber R. If the shutter 82 is opened even after cleaning, drying of the fuzz chamber R is promoted. The cleaning water can be supplied from the discharge window 80 and discharged from the short hair cutting unit 10 together with the shavings. That is, the discharge window 80 can be a cleaning water introduction window. Further, fluff can be discharged by swinging the electric razor with the shutter 82 opened without using cleaning water.

  As described above, when the functional structure including the opening window 81 that opens and closes the discharge window 80 is provided on the peripheral wall of the head case 9 facing the functional structure area F2, the opening body 81 is opened and the discharge window 80 is opened. Is opened toward the outer surface of the head case 9, so that the hair in the hair chamber R can be easily discharged. Moreover, by supplying the washing water from the short hair cutting unit 10, the hair can be discharged together with the washing water while washing the inside of the fuzz chamber R with water. Therefore, it is possible to facilitate the cleaning of the fluff accumulated in the fluff chamber R and easily clean the fluff chamber R. Further, if the opening / closing body 81 is configured by the shutter 82, the structure of the opening / closing body 81 can be simplified, and the discharge window 80 can be opened toward the outer surface of the head case 9 by a simple operation of sliding the shutter 82. Can do. According to the shutter 82 provided with the operation piece 83 for hooking, the slide operation of the shutter 82 can be accurately performed with one hand using the operation piece 83. At this time, since the operation piece 83 is provided near the main body case 1 of the shutter 82, it is easy to operate when opening and closing the shutter 82 while grasping the main body case 1.

Example 8 FIGS. 17 and 18 show Example 8 of an electric shaver according to the present invention. In the present embodiment, the opening / closing body 81 similar to that of the seventh embodiment is provided in the head case 9, but the upper end of the guide groove 86 is exposed to the front end surface 9 c of the head case 9, which is different from the seventh embodiment. According to such an opening / closing body 81, most (a part) of the shutter 82 can protrude from the tip of the head case 9 in a state where the shutter 82 is slid to open the discharge window 80. Note that the shutter frame 85 as viewed from the front is formed in a U-shape. Thus, when most of the shutter 82 is protruded from the tip of the head case 9, it can be displayed by the shutter 82 that the discharge window 80 is opened. Further, since it is possible to visually confirm that the discharge window 80 is open, it is possible to effectively prevent whisker cutting while the discharge window 80 is open.

Example 9 FIG. 19 shows Example 9 of an electric shaver according to the present invention. In this embodiment, the shutter 82 is configured to be slidable in the circumferential direction of the head case 9. Accordingly, the guide piece 84 is provided on the upper and lower edges of the shutter 82, and the operation piece 83 is provided on the outer surface of the right end of the shutter 82. When the shutter 82 is slid to the left as viewed in FIG. 19 from the state shown in FIG. 19, the discharge window 80 can be opened toward the outer surface of the head case 9 to discharge the dust. Thus, the sliding direction of the shutter 82 may be not only the direction along the central axis P2 of the razor head 2, but also the circumferential direction of the razor head 2.

(Example 10) FIG. 20 shows Example 10 of an electric shaver according to the present invention. In this embodiment, the opening / closing body 81 includes a swing shaft 90 that is pivotally supported by the head case 9, and the opening / closing body 81 is supported by the head case 9 so as to be swingable open / close.
