(Background technology) Conventionally, in reciprocating electric razors in which an inner blade slides back and forth on the inner surface of an outer blade that has many blade holes for introducing hair, the outer blade has been designed to better introduce relatively long hair. Proposals have been made to make the blade hole an elongated hole or to provide a three-dimensional slit in the bent strip corresponding to the top of the outer cutter.

確かに長穴では長い髭が導入され易いが、一度
この刃穴内に導入された髭が内刃ブレードにより

間隔を狭くする方法が採用されている。
It is true that long hairs are easily introduced into the slotted hole, but once the hairs are introduced into the hole, they may pass through the hole before being cut by the inner blade, or the tips of the hairs may end up on the way through the hole. The disadvantage was that a large portion of the hair was cut off and a large portion remained, making it impossible to shave shortly in a short period of time. Therefore, in view of this drawback, in order to increase the rate at which the inner cutter passes through the cutter hole, methods of increasing the frequency and swing width of the inner cutter and methods of narrowing the interval between the inner cutter blades have been adopted.

However, the former has the disadvantage that vibration, noise, and load on the main body increase, the life of the motor and vibrator for driving the inner blade is shortened, and rechargeable razors can be used less often on a single charge. Ta. On the other hand, in the latter case, the number of inner cutter blades increases, and the contact area with the outer cutter increases accordingly, resulting in an increase in load.Also, more hair chips adhere to the inner cutter blade, and the inner cutter One drawback was that the blades were spaced closely, making it difficult to clean.

Furthermore, with long blade holes, the length of the crosspiece between the outer blade holes is longer than with short blade holes, so when the skin is pressed against the outer blade, the amount of deflection of the crosspiece becomes large, causing the inner blade to bend. It also has the disadvantage that the outer cutter is easily damaged.

(Effects of the Invention) As described above, according to the present invention, there is an outer cutter formed by drilling a long hole for introducing whiskers and a short hole shorter than the long hole, and a plurality of outer cutters that are in sliding contact with the inner surface of the outer cutter. In an electric razor blade equipped with an inner blade, the pitch between the inner blades facing the elongated hole is
Since the pitch is narrower than the pitch between the inner blades facing the short hole, the hair introduced into the long hole can be quickly and reliably caught and cut by the inner blade with a short pitch, so the hair can be removed in a short time. It has the effect of allowing you to shave your hair short.
