利点がある。
As this type of mesh outer cutter, the present applicant previously proposed an outer cutter that has both a thin hair introduction hole area and a thicker hair introduction hole area (for example, in the patent application (Sho 60-148685). According to this, it is possible to achieve a close shave while ensuring the strength of the outer blade. Also, people who don't get irritated by razors can get a close shave by focusing on the thin hair introduction hole area, and people who don't like razors can remove the thin hair introduction hole area and use the thick hair introduction hole area. It has the advantage of being able to shave without irritation by using it intensively.
しかし、外刃の外観を見ただけでは、薄肉とす

との見分けが難しいため、実際には、その使い分
けが容易ではない。
However, just by looking at the appearance of the outer cutter, it is difficult to distinguish between the thin hair introduction hole region and the thicker hair introduction hole region, so in reality, it is not easy to use them properly.

In such cases, when shaving closely, focus on the thin hair introduction hole area A of the outer blade against the skin, and when shaving to a normal depth, use the thicker hair introduction hole area B. All you have to do is press it firmly against your skin and shave. Further, these areas A and B can be easily identified by identification display means provided on their surfaces, and their use can be easily performed.

ができるというものである。 Further, for example, when the shape and size of the hair introduction hole 1 in the thin hair introduction hole region A are different from the shape and size of the hair introduction hole 3 in the thicker hair introduction hole region B, The former hair introduction hole 1 is made relatively wide and short in order to introduce short hair,
Even in the case where the latter hair introduction hole 3 is relatively small in width and long in length, the hair introduction hole 1 in the thin hair introduction hole area A can shave hair closely from the root. The thick hair introduction hole 3 in the hair introduction hole region B can reduce sagging of the skin to the extent that it is thicker, resulting in a better shave without causing irritation even with long hair. . Note that the shape of the hair introduction hole 1 in the hair introduction hole region A, which is thin, and the hair introduction hole 3 in the hair introduction hole region B, which is thicker than that,
Even if the sizes are different, the shape and size of these holes can often be clearly distinguished only by looking with a magnifying glass, so the shape and size of hair introduction holes 1 and 3 are different to the naked eye. It is difficult to distinguish areas A and B just by being different, so in this case as well, by providing identification display means on the surfaces of areas A and B, it is possible to easily identify them with the naked eye. That is what it is.
以下、本発明の一実施例を第１図ないし第５図

してなる。 Figure 1 shows an example of the outer blade of a vibrating electric shaver. , a large number of relatively wide and short hair introduction holes 1 and a rib 2 between the hair introduction holes 1 and 1.
A region A is formed over almost the entire length in the left-right direction (inner blade vibration direction, the same applies hereinafter), and the front and rear sides of the region A are obliquely intersected at a predetermined angle with respect to the left-right direction, and the bristles are Regions B, B in which hair introduction holes 3 longer than the length of the introduction holes 1 are arranged in a staggered manner in the left and right direction, and numerous micropores 4 to the extent that no hair can be introduced are formed further forward and rearward of the region B, respectively. It also has micropore regions C and C, and a solid portion D is formed around these regions A, B and C.

前後の微細孔領域Ｃ，Ｃの各厚みは40〜48μm、
べた部Ｄの板厚は35〜45μmとする。 As shown in FIGS. 3a and 3b, the thickness t 1 of the area A where the short hair introduction holes 1 of this outer blade are arranged is greater than the thickness t 2 of the area B where the long hair introduction holes 3 are arranged. Also form a thin layer. Specifically, the thickness of area A t 1
is set to 40 to 50 μm, preferably 45 μm, and the thickness t2 of the other region B is set to 55 to 65 μm, preferably 55 μm.
The thickness of each of the front and rear micropore regions C and C is 40 to 48 μm,
The plate thickness of the solid portion D is 35 to 45 μm.
そして、外刃の領域Ｂの表面は外刃金属の光沢

We are trying to increase our popularity.
次に、上記構成の領域Ａ，Ｂをもつ外刃の製造
方法の一例を説明する。ここでは電鋳法を採用す
る。 Next, an example of a method for manufacturing an outer cutter having regions A and B configured as described above will be explained. Here, electroforming is used.

膜１１によつて覆われていない表面Ｓ、すなわち
その母型１０の導電表面に電気絶縁膜１１の厚さ
を超える第１次電着層１３を形成する。 First, as shown in FIG. 2a, on the surface of a conductive electroforming mold 10, an electrical insulating film 11 having a pattern corresponding to the hair introduction holes 1 in the thin hair introduction hole area A is formed, and each A notch 12 is formed in the electrical insulating film 11. This notch 12 is for making the thickness t 1 of the region A thinner than the thickness t 2 of the other region B, as will be described later. As is well known, the electrical insulating film 11 is formed by coating or pasting a photoresist on the surface of the electroforming mold 10, partially exposing it to light using a mask, and developing it. Next, the electroforming mother mold 10 on which the electrical insulating film 11 was formed
is immersed in an electrodeposition tank (not shown) to perform primary electrodeposition, and as shown in FIG. A primary electrodeposited layer 13 having a thickness exceeding the electrical insulating film 11 is formed on the conductive surface of the mold 10 .
この第１次電着により、上記切欠部１２の部分
に、いわゆる捨て電着部１４が形成される。 By this primary electrodeposition, a so-called sacrificial electrodeposition portion 14 is formed in the notch portion 12 .
次いで、上記母型１０を重クロム酸カリウム等

つても、上記捨て電着部１４上に電着部１６が形
成される。 Next, the matrix 10 is immersed in an aqueous solution of potassium dichromate or the like to perform a peeling treatment on the surface of the primary electrodeposited layer 13, and then a layer of metal such as nickel or an alloy of nickel and cobalt is applied. Secondary electrodeposition is performed to form the first electrodeposited layer 1 as shown in Figure 2c.
A second electrodeposited layer 15 is formed on the surface of the hair introduction hole 3 to form a rib 2 between the hair introduction holes 1 and 1. Also by this secondary electrodeposition, the electrodeposited portion 16 is formed on the sacrificial electrodeposition portion 14 .
領域Ｂについても同じ母型１０上で同時に電鋳
するが、この領域Ｂの電着では、第５図に示すよ
うに、捨て電着部は形成しない。 Region B is also electroformed on the same master mold 10 at the same time, but in the electrodeposition of region B, no sacrificial electrodeposited portion is formed, as shown in FIG.
最後に、母型１０を電着槽から引き上げて第２

捨て電着部１４，１６は毛導入孔１となる部分内

層１３と共に残される。 Finally, the mother mold 10 is pulled up from the electrodeposition bath and the second
When the secondary electrodeposited layer 15 is peeled off from the peeled surface of the primary electrodeposited layer 13, as shown in FIG. 2d and FIG. An outer cutter having the following is obtained. When the second electrodeposited layer 15 in area A is peeled off,
Since the sacrificial electrodeposited portions 14 and 16 are formed within the portion that will become the hair introduction hole 1, they are left on the mother die 10 side together with the primary electrodeposited layer 13.
しかるときは、第３図ａ，ｂに示すように、領
域Ａの厚みt1は、領域Ｂの厚みt2よりも、捨て電
着部１４，１６に電着された分だけ薄くなる。す
なわち、電着法においては単位面積当りの電着量

リブ２の厚みが領域Ｂのそれよりも薄くなること
になる。リブ２の厚みは電着厚さに比例し、電着
厚さが薄くなればリブ厚が小さくなるからであ
る。 In this case, as shown in FIGS. 3a and 3b, the thickness t 1 of region A becomes thinner than the thickness t 2 of region B by the amount of electrodeposited portions 14 and 16. That is, in the electrodeposition method, the amount of electrodeposition per unit area is approximately constant, and therefore, by forming the sacrificial electrodeposition parts 14 and 16 in area A as described above, the electrodeposition area per unit area can be reduced. If it is increased more than that in area B, the electrodeposition thickness in area A, that is, the thickness of the rib 2, will be thinner than that in area B. This is because the thickness of the rib 2 is proportional to the electrodeposition thickness, and as the electrodeposition thickness becomes thinner, the rib thickness becomes smaller.
領域Ａと領域Ｂの境界の厚みが急激に変化する
ことによる機械的強度の変化並びに内刃との当り

厚みを徐々に領域Ｂの厚みに近づけることが好ま
しい。これは、上記電鋳法で、領域Ａの外周部の
捨て電着部１４，１６となる切欠部１２の開孔面
積を領域Ｂに近づけるに従い徐々に小さく設定す
ればよい。 To prevent changes in mechanical strength and poor contact with the inner cutter due to sudden changes in the thickness of the boundary between area A and area B, the thickness of the outer periphery of area A is gradually increased to the thickness of area B. It is preferable to get close to . This can be done by setting the opening area of the notch 12 which becomes the sacrificial electrodeposited parts 14 and 16 on the outer periphery of the area A to gradually become smaller as it approaches the area B in the electroforming method described above.
なお、上記電鋳後に領域Ａのみの表面に金メツ
キを施す。 Note that after the electroforming, only the surface of area A is plated with gold.

A large number of small holes (indicated by the symbol P in the enlarged view in Figure 1) are provided on the other surface of the outer cutter so that the dark area inside the outer cutter is visible from the outside when the outer cutter is attached. It may be made to exhibit a darker color.

According to the present invention, since the outer blade has both the thin hair introduction hole area A and the thicker hair introduction hole area B, the hair introduction hole area A is thin.
It is possible to shave hair closely from the root with the thick hair introduction hole area B, and to shave more shallowly than that in the thick hair introduction hole area B. Moreover, when looking at the mechanical strength of the entire outer blade, the thickness of the hair introduction hole area A is Even if it is formed thin, sufficient mechanical strength can be ensured by the presence of the hair introduction hole region B, which is thicker than the thickness.
