In an electric shaver in which an inner cutter is in sliding contact with the lower surface of a dome-shaped outer cutter serving as a fixed cutter, a large number of introduction holes 6 are provided as shown in Fig. 11.
A device has been devised in which radial grooves or convex grooves 6b''k are formed on the surface of the outer cutter 6' which is perforated to raise the bristles, but the bristles extend in various directions. With a razor, you can raise the hair that is lying in the direction in which the outer blade 6' slides, but in order to raise and cut the hair that is lying in the opposite direction, you have to move the electric razor back and forth on the desk many times. However, the drawback was that it took time to shave the hair short.

態で切断され、短く剃り上がることとなる。1 to 4 show a first embodiment of the present invention, and FIG. 2 shows an electric shaver to which the present invention is applied. In the figure, 1 is a bottomed cylindrical main body, 2 is a holder housing provided on the upper part of the main body 1, and a drive frame 3 is provided inside the holder housing. This drive frame 3
The blade base 4a of the blade block 4 provided at the upper part of the holder housing 2 converts the rotational motion of the motor into reciprocating motion.
The i'' movable blade 5 is configured to reciprocate and slide relative to the fixed blade 6 below it. FIG. 3 shows the movable blade 5, which has a large number of comb-shaped blades 5a arranged in a row on its front edge, and the contact surface of these comb-shaped blades 5a with the skin, that is, the hard and red blades 6. Grooves 5b are formed along the direction of the grooves of the comb-like blades 5a on the surface opposite to the sliding surface, and these grooves 5b and a part of the convex comb-like blades 5a on both sides are formed with ↓ A raised portion 7 having an uneven shape is formed as a whole. On the other hand, the fixed blade 6 that comes into sliding contact with the movable blade 5 is constructed by arranging a large number of comb-like blades 6a on the front edge of the blade as shown in FIG. In this operation, the drive frame 3 swings due to the rotation of the motor, and the movable blade 5 reciprocates while slidingly contacting the fixed blade 6. At this time, as shown in FIG. Since the raised part 7 provided on the contact surface side reciprocates and rubs the surface of the skin S, the lying hairs I (present on the surface of the skin S) are raised, and the movable blade 5 and the blade of the fixed blade 6 The hair gets into the groove and is cut when the hair is completely brushed, resulting in a short shave.

できる。Next, FIG. 5 shows a second embodiment. In this embodiment, a large number of thin-walled comb-like blades 5d are arranged in a row on the front edge of the movable blade 5C, and on the upper surface thereof, that is, the surface in contact with the skin, a raised part 7B having the same shape as the comb-like blades 5d is made of metal such as rubber. They are also made of a material with a high coefficient of friction and are placed one on top of the other. Even in this example, the friction with the skin is large for the raised portion 7aK, and the first
Similar to the embodiment, it is possible to reliably raise the hair that has fallen down and shave it short.

In this embodiment, raised portions 7 consisting of a comb-shaped blade 5a and a groove portion 5b as in the first embodiment are formed at regular intervals on the front edge of a movable blade 5e, and a thin wall is formed between these raised portions 7. It is constructed by disposing 5ft of crossness blades respectively. In this embodiment, the lying hair is raised by the raising part 7, and the hair can be cut short at a position close to the root by the crossness blade 5f located next to the raising part 7 as shown in Fig. 6←). There is.

。(Invention/1 Effect) According to the present invention, a movable blade having a comb-like blade that can come into contact with the skin is slid back and forth against a fixed blade having a comb-like blade. In this, a raised part is formed on the side of the movable comb-like blade that comes into contact with the skin, so it is usually used for shaving!
It has effects such as being able to reliably cut off lying hair, curly hair, etc. that are difficult to remove in a short time, and eliminating any unshaved hair.
