  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  As shown in FIG. 2, the hair cutter 1 includes a main body 2 referred to as a so-called clipper and an abutting member 10 attached to the tip 2 a of the main body 2.

  As shown in FIG. 1, a blade portion 3 is provided at the tip 2 a of the main body 2. The blade portion 3 includes a comb-shaped fixed blade 4 and a comb-shaped movable blade 5 that is slidably contacted with the fixed blade 4 and driven to reciprocate with respect to the fixed blade 4. The movable blade 5 is reciprocally driven electrically by a drive mechanism (not shown) built in the main body 2. By moving the movable blade 5 back and forth, the hair is cut between the fixed blade 4 and the movable blade 5.

  An abutting member 10 that abuts against the scalp G (skin) when cutting the hair with the blade 3 is disposed around the edge of the blade 3. The abutting member 10 is integrally formed at the distal end portion of the fixed cylinder portion 14 that is detachably fixed to the main body 2. Reference numeral 15 in FIG. 2 denotes an attaching / detaching operation button.

  As shown in FIG. 3, the contact member 10 includes a comb member 13 in which a large number of comb teeth portions 12 are arranged in parallel. In the comb member 13, a plurality of comb tooth portions 12 are arranged in parallel to each other at equal intervals in the blade width direction F of the blade portion 3. The tip of each comb tooth portion 12 is a flush skin contact surface 11.

  The comb members 13 in this example are arranged on both sides of the front D and the rear E with the blade portion 3 interposed therebetween. Further, the skin contact surface 11 at the tip of the comb member 13 is disposed substantially perpendicular to the protruding direction A of the blade portion 3 as shown in FIG. Here, the skin contact surface 11 extends in a straight line perpendicular to the protruding direction A of the blade portion 3 when viewed from the side. An important function of the skin contact surface 11 is to stably hold the blade 3 so that the pressing force of the tip of the blade 3 against the skin does not become too high. Excessive pressing force causes discomfort associated with skin damage and irritation when the skin contacts the blade portion 3. Therefore, the irritation reduction is achieved by the skin contact surface 11.

  The protruding direction A of the blade portion 3 is inclined so as to be positioned forward D toward the tip with respect to the longitudinal direction B of the main body 2. Moreover, the front-end | tip of the blade part 3 is protruded and arrange | positioned outward from the skin contact surface 11 by a little predetermined dimension. As shown in FIG. 4, the distal end of the fixed blade 4 protrudes outward by a predetermined dimension M from the skin contact surface 11 that hits the scalp G, and the distal end of the movable blade 5 is inward by a predetermined dimension N from the skin contact surface 11. It is placed in a position that goes into the direction. The dimensions of M and N can be changed as appropriate.

  The body 2 of the hair cutter 1 having the above configuration is held by hand, and the body 2 is pushed forward D while the skin contact surface 11 at the tip of the comb member 13 is applied to the scalp G as shown in FIG. The hair H is cut (pressed) with the blade portion 3. At this time, even if the cutting edge direction of the blade portion 3 is perpendicular to the scalp G, the skin contact surface 11 comes into close contact with the scalp G, so that the comb member 13 is stabilized and the skin irritation can be reduced. On the other hand, as shown in FIG. 5 (b), even when the main body 2 is moved backward E and the hair H is cut (drawn) by the blade portion 3, the blade portion 3 is caused by the presence of the skin contact surface 11. The force of pressing is less likely to concentrate on the scalp G, the effect of reducing skin irritation is obtained, and the skin is less likely to be damaged. In addition, since the tip of the comb member 13 is the skin contact surface 11 in both of the above-described push cutting and pulling, the hair H to be cut is likely to be raised and trimmed by the skin contact surface 11 before cutting. In addition, since the hair H is combed by the plurality of comb tooth portions 12, the blade portion 3 can easily capture the hair H and the cutting performance is improved. As a result, anyone who is not an expert can easily obtain a safe and clean finish.

  In addition, since the comb members 13 are arranged on both the front and rear sides of the blade part 3, the skin contact surface 11 presses the scalp G on both sides of the blade part 3. Thereby, the comb member 13 becomes more stable, and a further stimulus reduction effect is obtained.

  Moreover, since the skin contact surface 11 at the tip of the comb member 13 is disposed substantially perpendicular to the protruding direction A of the blade portion 3, the skin contact surface 11 makes it difficult to damage the scalp G at the cutting edge of the blade portion 3. There is also an advantage that the introduction property of the hair into the portion 3 can be secured.

  Further, only the tip of the fixed blade 4 is disposed so as to protrude from the skin contact surface 11, and the tip of the movable blade 5 is disposed so as not to protrude from the skin contact surface 11. Thus, the hair H can be cut without pressing the tip of the movable blade 5 against the scalp G while the tip of the fixed blade 4 is in close contact with the scalp G, and the scalp G can be hardly damaged by the tip of the movable blade 5.

  Further, since the gaps between the plurality of comb teeth 12 are opened to the front D and the rear E, respectively, the side edges of the comb teeth 12 without the cut hair H collecting in the vicinity of the blade 3. It is guided from the 12a side (FIG. 1) to the gap between the comb tooth portions 12 and smoothly discharged. In addition, since the comb member 13 can be attached to and detached from the main body 2, the blade portion 3 and the comb member 13 can be easily cleaned.

  In the above embodiment, the comb members 13 are provided on both sides of the front D and the rear E of the blade portion 3, respectively. However, the comb members 13 may be provided at least on the front D, and the comb members 13 on the rear E can be omitted. It is. That is, the comb member 13 is provided only in the front D where the angle formed between the scalp G and the longitudinal direction B of the main body 2 is the acute angle α (see FIG. 4) when the cutting edge direction of the blade portion 3 is perpendicular to the scalp G. Thus, when pushing forward D, either the usage mode shown in FIG. 5A or the usage mode shown in FIG. 7 (conventional example) can be freely selected. On the other hand, in the case of cutting to the rear E, by selecting the usage mode of FIG. 5B so that the skin contact surface 11 of the front D is in contact with the scalp G, the conventional cutting (FIG. 7 ( A stimulus reduction effect that cannot be obtained from b)) can be obtained. Moreover, there is also an advantage that the entire comb member 13 can be made compact by omitting the rear E comb member 13 as in this example.

  Moreover, in the said embodiment, although the skin contact surface 11 was linearly formed at right angle with the protrusion direction A of the blade part 3, it is good also as circular arc shape like FIG. That is, the skin contact surface 11 may be formed in an arc shape that is highest at the end portion close to the blade portion 3 and gradually decreases as the distance from the blade portion 3 increases. In this case, the skin contact surface 11 can be easily applied to a narrow scalp portion such as the back of the ear, and the cutting work is accelerated.

  Moreover, in the said embodiment, although arrange | positioned so that the front-end | tip of the movable blade 5 may not protrude from the skin contact surface 11, the structure which protrudes and arrange | positions the front-end | tip of the movable blade 5 rather than the skin contact surface 11 is also possible.
