材Q3を設けたものが考えられたが、引張り材Q3
でひげを引張るにはそられるひげＰが可動刃Q1
と固定刃Q2の厚み分以上の長さを有しなければ
引張れないという欠点があつた。 When shaving with a comb type electric razor, there is a drawback that it is not possible to shave deeper than that due to the thickness of the movable blade Q 1 or fixed blade Q 2 that faces the skin M as shown in Figure 12. Ta. Furthermore, if the thickness of the movable blade is made smaller and the movable blade is placed closer to the skin, deeper scratches can be achieved, but this has the disadvantage of increasing irritation to the skin. As an improvement plan for these, it was considered that the tension material Q 3 was provided as shown in Figs. 13 and 14, but the tension material Q 3
To pull the beard with the movable blade Q 1
It had the disadvantage that it could not be pulled unless it had a length equal to or greater than the thickness of the fixed blade Q2 .
したがつて、この発明の目的はひげの長さにか
かわらず、肌当りよく深ぞりをすることができる
電気かみそりを提供することである。 Therefore, an object of the present invention is to provide an electric razor that can deeply shave the beard with good contact with the skin, regardless of the length of the beard.

する。 The details of the movable blade 13 and the fixed blade 12 are shown in FIGS. 2 to 4. The movable blade 13 is stacked on the fixed blade 12, and the driver 16 of the movable blade 13 is attached to the fixed blade 12.
The fixed blade 12 is fixed to the skin protection member 15 by a stopper 17, and at this time, the boss 18 of the member 15 and the driver 16 serve as guides for the movement of the movable blade 13. Also, the movable blade 13
A push-up spring 14 is interposed between the movable blade 13 and the skin protection member 15 to press the movable blade 13 against the fixed blade 12. In addition, each blade part 12a, 13 of the fixed blade 12 and the movable blade 13
a are in mutual contact with each other, and the blade portion 13a of the movable blade 13 is warped and bent at the blade groove 12b of the blade portion 12a of the fixed blade 12 so as to enter into the blade groove 12b.
Therefore, the operation of the blade part 13a is such that the blade part 13a is located in the blade groove 12b between the blade parts 12a of the fixed blade 12, but as it approaches the blade part 12a, it crosses from the root side of the blade to the blade part 12a. Moves back and forth so that it is positioned above.

一方可動刃１３側が肌側となる場合はその刃部１
３ａが固定刃刃部１２ａ間に進入している分だけ
固定刃１２が肌に接近するので同様に深ぞりが可
能となる。 Figures 5 and 6 show the shaving operation of this electric shaver. In the figure, the fixed blade 12 side is skin M.
The movable blade 13 is shown as being pressed against the movable blade 13.
The operating principle is the same even when the side is the skin M side (in this case, the skin protection member contacts the skin as described above). When the fixed blade 12 side touches the skin M, the blade part 1
A whisker P is introduced into the blade groove 12b between the blade grooves 2a. The movable blade 13 moves back and forth so that the blade portion 13a moves into the blade groove 12b.
When located in the blade groove 12b,
The blade part 13a catches the beard P near the base of the beard P, and as it approaches the blade part 12a, it pulls up the beard P while keeping it caught, and cuts it when the blade parts 12a and 13a intersect. As a result, the cutting height of the beard P is the dimension δ a from the skin contact surface 19 of the fixed blade 12 to the penetration depth position of the blade portion 13a, which is smaller than the thickness δ b of the blade portion 13a, so that it will not be deeply scratched. Become.
On the other hand, if the movable blade 13 side is the skin side, the blade part 1
Since the fixed blade 12 approaches the skin by the amount that the fixed blade 3a enters between the fixed blade blade portions 12a, deep scratching is also possible.

実施例と同様である。 A second embodiment of the invention is shown in FIGS. 7 and 8. That is, in this case, the fixed blade 12' is in contact with the skin, and the fixed blade 12' is fixed to the comb 11' by a stopper 17', and the movable blade is guided by the stopper boss 20, and the movable blade 13 ' and comb 1
1' is interposed with a push-up spring 14'. The thickness of the blade portion 13'a becomes smaller toward the tip end. In this case, the elasticity of the blade portion 13'a increases and the sliding load on the movable blade 13' is reduced, and is the same as in the first embodiment.

は第１の実施例と同様である。 A third embodiment of the invention is shown in FIG. That is, this means that the blade portion 21 of the movable blade 13' is the fixed blade 1.
It is curved convexly towards the 2' side. As a result, as shown in the figure, the crossness effective area H of the blade part 1 is in a straight line state.
3a, the range η 1 expands to the range η 2 , and the deep groove area in the blade groove 12b expands. The rest is the same as the first embodiment.
この発明の第４の実施例を第１０図に示す。す

接触となるため摺動が滑らかとなり、負荷の低減
となる。 A fourth embodiment of the invention is shown in FIG. That is, the blade parts 12a and 13a are both trapezoidal in plane, and the mutual angle α of the blade parts 12a and 13a is set to be 0° or more. As a result, the mutual contact between the cutting edges becomes point contact, resulting in smooth sliding and a reduction in load.

確保できる。 A fifth embodiment of the invention is shown in FIG. That is, every plurality of blade grooves 22a of the movable blade 13'' are made into long grooves to disperse floating force into the fixed blade groove due to the sliding of the blade portion 13''a of the movable blade 13''. At the same time, non-uniformity in the warpage of the blade portion 13''a can be corrected at the time of assembly, and good sliding and cutting quality can always be ensured.
以上のように、この発明の電気かみそりは、く
し状可動刃の刃部をくし状固定刃の刃溝の内部に
