用に抗して内方に押込まれる。 The cutting unit 5 is connected to the electric motor 1 by means of a hollow spindle 6 (see Fig. 2), teeth numbers 7 and 8, and a shaft 9.
0 to rotate the cutting unit relative to the corresponding net blade 3. A gear 7 is rotatably supported on a pin 11, and the pin 11 is fixed to a mounting plate 12. A recess 13 is formed in the gear 7, and this recess 13
is closed by a cover plate 14. The flange 15 at the end of the hollow spindle 6 is accommodated in this recess.
The shape of the flange 15 is made non-circular, for example square,
And by matching the shape of the recess 13, a drive connection is obtained which transmits the rotary movement of the gearwheel 7 to the spindle 6, which can be rotated in any direction. A large part of the spring 16 is arranged within the hollow spindle 6 and compressed between it and the hollow spindle gear 7 to produce a force which directs the spindle 6 towards the cutting unit 5. Since the cylindrical part 17 of the spindle 6 is pressed against the cutting unit 5, this force is transmitted to the cutting unit and via the cutting unit to the screen blade 3, which is then pressed against the rim 18.
is pressed against the net blade holder 2. Under the action of external forces occurring during use of the shaving device, the blades 3 together with the cutting unit 5 and the spindle 6 are pushed inward against the action of the spring 16.

を連結する。 The cutting member 21 is attached to the cutting unit 5 (see FIG. 3).
The cutting member 21 is mainly composed of a center portion 22, cutters 23 are formed on the periphery of the center portion 22, and these cutters 23 are attached to the center portion 22 by arms 24. Each cutter 23 is provided with a lead cutter 25, and this lead cutter 25 is connected to a lead cutter unit 26. In this case, the lead cutter unit 26 is provided with a center portion 27, and an arm 28 is attached to the center portion 27 to connect the lead cutter 25 to the lead cutter unit 26.
Concatenate.
切断部材２１の中心部２２とリードカツタユニ
ツト２６の中心部２７との組合せ状態において例
えば点溶接により互いに取付ける。 In the assembled state, the center portion 22 of the cutting member 21 and the center portion 27 of the lead cutter unit 26 are attached to each other by spot welding, for example.

は網刃３に対してほぼ交差する方向に指向する。 The end 29 of the cutter 23 and the end 30 of the reed cutter are crimped against the screen blade 3 having the hair entry hole 4 in order to apply a spring pressure to the cutting unit 5 as described above with reference to FIGS. Due to the elastic properties of the arm 28, the lead cutter 25 has a corresponding cutter 23.
This movement is oriented in a direction substantially transverse to the net blade 3.
リードカツタ２５の端部３０に突出部３１を設
け、この突出部３１に接触端縁３２を設ける。 A protrusion 31 is provided at an end 30 of the lead cutter 25, and a contact edge 32 is provided on this protrusion 31.

照）。 4 and 5 the operation of the cutting unit 5 is shown, in this case a side view of part of the cutting unit and a cross section of the net blade, and the skin 33 with the beard 34.
A part of the diagram is shown diagrammatically. When the hair 34 enters the hair entry hole 4, the hair 34 first comes into contact with the contact edge 32 of the reed cutter 25 at position A due to the rotation of the cutting unit 5 with respect to the net blade 3 (see FIG. 4).

合するカツタ２３の壁３６と案内壁３５との間の
角度αは90℃以下にしなければならない。 The contact edge 32 is a sharp edge that only slightly penetrates the whiskers 34 without cutting them. The reaction force applied to the lead cutter 25 by the whiskers 34 is in the opposite direction to the moving direction P. This reaction force is offset by component N 1 of the normal force N applied to the lead cutter 25 by the guide wall 35 of the cutter 23 . In this case, to simplify the explanation, cutlet 23
The slight frictional force between the lead cutter 25 and the lead cutter 25 was ignored. Lead cutter 2 due to component N 2 of vertical force N
5 along the guide wall 35. The angle α between the wall 36 of the cutter 23 that engages the net blade 3 and the guide wall 35 must be 90° or less.
特に皮膚本来の弾性のためひげ３４はリードカ
ツタ２５とともに移動し、カツタ２３のリード端
縁３７はひげの位置Ｂに達する（第５図参照）。
従つてひげ３４は網刃３とカツタ２３との共働に

て切断され、従つてリードカツタ付切断ユニツト
を有するひげそり器を使用すればリードカツタを
持たないひげそり器に比べると皮膚に残るそり跡
はきれいになる。 In particular, due to the inherent elasticity of the skin, the whiskers 34 move together with the reed cutter 25, and the lead edge 37 of the cutter 23 reaches the whisker position B (see FIG. 5).
Therefore, the beard 34 is pulled away from the skin 33 by the distance from A to B before being cut at position B by the cooperation of the net blade 3 and the cutter 23. If there is no lead cutter 25, the beard 34 will be cut at position A, and therefore, if a shaving device with a cutting unit with a lead cutter is used, the shaving marks left on the skin will be cleaner compared to a shaving device without a lead cutter.
比較のために突出部を持たないリードカツタ２
５′を第５図において点線で示す。このリードカ
ツタ２５′は位置Ｃにおいてひげ３４に接触し、
剃られるまでに距離BCに相当する距離しか引張
ることができない。従つて突出部３１を使用する
とひげを引張るとき距離ACだけ余分に引張り、
リードカツタの作用が改善される。 For comparison, lead cutter 2 without a protrusion
5' is indicated by a dotted line in FIG. This lead cutter 25' contacts the beard 34 at position C,
It can only be pulled a distance equivalent to distance BC before it is shaved. Therefore, when using the protruding part 31, when pulling the beard, it will be pulled an extra distance AC,
The action of the reed cutter is improved.
突出部３１とはリードカツタ２５の端部３０を
一層厚くすることを意味し、全体にわたり厚いリ
ードカツタユニツトと比べるとリードカツタユニ
ツトの重量増加は相当小さく弾性アーム２８の剛
性は増加しないという利点がある。 The protruding portion 31 means that the end portion 30 of the reed cutter 25 is made thicker, and compared to a reed cutter unit that is thicker overall, the increase in weight of the reed cutter unit is considerably small and has the advantage that the rigidity of the elastic arm 28 does not increase. .
