The movable blade 40 and fixed blade 41 of the trimmer block 4 installed in this manner are placed close to the upper end of the curved outer blade 21, and their cutting edges are directed forward and diagonally downward. By determining the direction of the cutting edge in this way, the thickness of the trimmer block 4 at the front and back becomes thinner, and the thickness at the front and back of the blade frame 2 including the trimmer block 4 becomes thinner. Further, the front edge of the base plate 43 is an inclined surface, and the cutting edge of the front edge of the fixed blade 41 and the movable blade 40 that contacts the upper surface of the fixed blade 41 by the spring pressure of the presser spring 42 and the front edge of the base plate 43 are arranged in a straight line.

The drive mechanism for reciprocating the movable blade 40 of the trimmer block 4 includes a driver 10 that converts the rotational motion into reciprocating motion, a joint 49 attached to the driver 10, and a mounting board 4 of the trimmer block 4.
It consists of a trimmer drive rod 46 attached to the back of the hanging piece of No. 4. The vertical center portion of the hanging piece of the mounting board 44 is supported by a shaft 445 that protrudes rearward from the center of the back surface of the hanging piece of the mounting board 44.

It has a receiving groove 48 in a facing position, and receives the movement of the drive element 10 via a joint 49 and swings, thereby causing the movable blade 41 to reciprocate. The joint 49 connects the drive element 10 so that it can freely rotate up and down by fitting the shaft hole 490 into the shaft 105 protruding from both sides of the cylindrical shaft 102 of the drive element 10.
The opening 26 of the blade frame 2 and the notch 2 at one end of the outer blade 21 are attached to the front end.
12, a receiving groove 48 for the trimmer drive rod 46
It has a shaft portion 491 that can be freely engaged with the shaft hole 4.
A protrusion 492 is provided on the inner surface of each side piece having elasticity extending rearward than the protrusion 492.
2 climbs over a pair of protrusions 106 that protrude to both sides at a position slightly below the rear of the cylindrical shaft 102 of the drive element 10 as the joint 49 rotates, and the joint 49
It is designed to give a click to the rotation.

The vertical rotation of the joint 49 about the left-right direction is performed in conjunction with the switch operation by the switch handle 7. Switch handle 7 and fitting 4
The aforementioned slider 71 and slide lever 20 are used to link the slider 9 with the slider 71 and the slide lever 20. A slide lever 20, which is disposed on the front surface of the mounting base 6 so as to be movable up and down and whose upper end projects onto the upper surface of the mounting base 6, is pushed up by a slider 71 that moves upward in accordance with the upward movement of the switch handle 7. There is an engagement window 2 that penetrates back and forth on the upper part that is slightly bent at the rear.
01 is an opening 20 that also passes through the lower part back and forth.
2 is formed, and is spring-biased downward by a return spring 205 disposed within the opening 202 and having its upper end abutted against the lower surface of the flange 69 of the mounting base 6 and its lower end abutted against the lower edge of the opening 202. The shaft portion 491 of the joint 49 is inserted through the upper engagement window 201.

When the switch handle 7 is moved upward, the slide lever 20 is also moved upward via the slider 71, and the slide lever 20 is moved upward to the shaft portion 491 of the joint 49.
Since the joint 49 is rotated until the shaft portion 491 engages with the receiving groove 48 of the trimmer drive rod 46, the movement of the driver 10 can be transmitted to the movable blade 40 of the trimmer block 4. However, as mentioned above, there is a gap between the upper end of the slider 71 and the lower end of the slide lever 20 at the lowest position among the three clicks given to the vertical movement of the switch handle 7. Even if the motor 9 is energized by pushing up the switch handle 7 to the middle position and deflecting the contact spring 91 with the pin 72 to close the circuit between the motor 9 and the dry cell battery 96, the slide lever 20
The joint 4 is not pushed up by the slider 71 but is lowered by the force of the return spring 205, and the inner cutter block 22 is reciprocated by receiving the rotation of the motor 9 via the driver 10.
9 is not engaged with the trimmer drive rod 46, the movable blade 40 of the trimmer block 4 is not driven. However, if the switch handle 7 is pushed up to the highest position as shown in FIG. Slide lever 20
Since the joint 49, which has the shaft portion 491 inserted through the engagement window 201 of the trimmer drive rod 46, is rotated, the shaft portion 491 is engaged with the receiving groove 48 of the trimmer drive rod 46. Trimmer drive rod 4
6, and the spherical protrusion 47 is attached to the movable blade 40.
The movable blade 40 is reciprocated by the swinging of a trimmer drive rod 46 that is engaged with an engagement seat 45 fixed to the movable blade 40. Furthermore, when the joint 49 is rotated in this manner, the protrusion 492 of the joint 49 rides over the protrusion 106 of the driver 10, and eventually the joint 46 moves itself to the engagement position with the trimmer drive rod 46. try to For this reason, the joint 49 self-maintains the state of engagement with the trimmer drive rod 46 when its shaft portion 491 is engaged with the trimmer drive rod 46.

When shaving by using the trimmer block 4 in which the movable blade 40 is driven in this way, the blade edges of the fixed blade 41 and the movable blade 40 and the tip of the base plate 43 are located in a straight line, so the movable blade 40
The blade edge of the outer blade 21 is in close contact with the skin without being obstructed by the substrate 43, and when performing a finishing shave with the outer blade 21 and the inner blade of the inner blade block 22, which can shave hair short, the outer blade 21 is It can be made long enough to be guided into a small introduction hole, and it can eliminate unshaved hair.

On the other hand, hair that has entered the interior of the trimmer block 4 through the gap between the movable blade 40 and the base plate 43 is
It passes between the lower surface of the substrate 43 and the upper surface of the movable blade 40 to the rear and accumulates there, but the rear edges of the movable blade 40 and the fixed blade 41 are located behind the substrate 43 and the rear wall 436, and as is clear from FIGS. 6 and 7, this space A is formed between the through hole 411 of the fixed blade 41 and the mounting board 44. The gasket 3 communicates with the lower space B of the upper piece of the mounting board 44 through the provided outlet 447 and only through the outlet 447, and further through the opening 260 in the front recess 25 of the blade frame 2.
It communicates with the space C which serves as a hair waste collection above the space 5. Therefore, when washing with water to wash away hair, if a water flow is introduced into the trimmer block 4 from the portion where the movable blade 40 and the fixed blade 41 protrude, the hair that has accumulated in the space A will be removed. Passing through the space B along with the water flow through the outlet 447,
Furthermore, the hair is discharged through the opening 260 of the blade frame 2 into the space C as a hair waste collection, and the hair that has reached this space C is washed with water by opening the blade frame 2 with respect to the main body housing 1. It can be removed.

When the switch handle 7 is pulled down, the slide lever 20 moves downward by the force of the return spring 205, rotating the joint 49 in the direction of lowering the shaft portion 491, so that the joint 49 and the trimmer drive rod 46 are is disengaged and returns to its original state.
