The connecting part 19 that connects the inner blade 7 and the second blade part 20 are connected to each other.
It is comprised of a groove 23 that engages with the first blade 21 via the moe rod 22 of the second blade part 20 to reciprocate the movable blade 21. The second blade portion 20 includes a comb-shaped fixed blade 24 and a fixed blade 2
4, a comb-shaped movable force 21 in contact with the movable blade 21
a push-up spring (1 not shown) that presses the fixed blade 24 against the movable blade 2 and the drive frame 22 that is held in the groove 23, and the base 2.
5, and a fixed blade 24, a movable blade 21, a drive frame 22, and a push-up screw are supported on the base 25.

First openings 26 supported by the spindles of the first casing 4 are formed in both 1+llIu of the base 25, and the second! The blade portion (A) is rotatably supported by the first casing 4 located near the first blade portion 6. The second blade part is accommodated in a second blade part housing chamber 27 formed in the first casing 4 or protrudes from the second blade part housing chamber 27 . The first casing 4 accommodates a driver 10, a motor 6, a battery path that serves as a power source for the motor 6, and a motor mounting bracket for attaching the motor 6 and battery row MX. Terminal pins connected to ten poles and one pole of the battery row are fixed to the motor Mx fittings and protrude from the first casing 4. first casing 4
A second casing 31 formed in a cylindrical shape from a synthetic resin material is rotatably inserted into the outer periphery of the casing, and the first casing 4 and the second casing 31 constitute a casing. A flange portion 33 is formed in the second casing 31, and the flange portion 3 is formed between the lid body 32 fixed to the first casing 4 with screws 34 and the first casing 4.
3 is retained. 2nd') On the inner circumferential wall of the casing 31, there is a protrusion 37 that connects a first horizontal part 35 and a second horizontal part 36 formed on both sides of the tapered part 34 and the tipped bar part 34 in the circumferential direction. It is formed. The protrusion 37 has a first casing 4 lever 39
The other end is a second opening 40 formed in both side walls of the base 25.
It is loosely fitted. As shown in FIG. 2, the second opening 4o is formed to be located obliquely forward and lower than the first opening 26 when the second blade part is completely accommodated in the storage chamber 27. . The first casing 4 is provided with a fixed contact 641, and the second casing 31 is provided with a movable contact 42. The second casing 31 has an elastic protrusion 43
is formed in the lid body 32, and a first groove 44 in which the elastic piece 43 engages when the fixed contact 41 and the movable contact 42 are separated, and a first groove 44 that engages the fixed contact 41 and the movable/movable contact. 42 is in contact with the second groove 45 in which the elastic protrusion 43 engages, and the fixed contact 41 and the movable contact 42 are in contact with each other, causing the first blade portion to extend and causing the drive element 10 to A third groove 46 is formed in the groove 23 to which the elastic protrusion 43 engages when the drive frame 22 is engaged, and the first blade portion 6
In an electric shaver in which the second blade part is located on the back side, the second groove 45 and the third groove 46 are
°If left open, when using the second blade part (a) after using the first blade part 6, you can use the second blade part without changing the position of your hand. . Also, as shown in FIG. 7, the second blade part is pressed to the right with respect to the first blade part 6! till The electric razor placed in the song,
If the second groove 45 and the second groove 46 are opened by 180 degrees, you will hardly have to shift your hand position unless you use the second blade part after using the first blade part 6. A second cutting edge can also be used.

In addition, in the embodiment, the second blade part (A) is rotated to protrude from the first casing 4, or the second blade part (A) is slid to protrude from the first casing 4. You can let me.

(Operation) Next, the operating state will be explained based on the above. 1st
2 and 2, the inner cutter 7 of the first blade portion 6 is stopped, and the second blade portion is moved so that the accommodation chamber 27j3 is in the first groove 4.
4, the fixed contact 41 and the movable contact 42 are separated from each other, and the lever 39 is located at the first horizontal portion 35. From this state, when the second casing 31 is rotated in the direction of arrow P with respect to the first casing 4 (7) as shown in FIG.
The fixed contact 41 and the movable contact 42 are in contact with each other, and the lever 39 is located in the first horizontal part 35, and the inner blade 7 of the first blade part 6 is driven. At the same time, the second blade part is housed in the housing chamber 27. From this state, when the second casing 31 is rotated in the direction of arrow P as shown in FIG. 8 with respect to the first casing 4,
The elastic protrusion 43 engages with the third groove 46, the fixed contact 41 and the movable contact 42 maintain contact, and the lever 39 passes through the tapered portion 34 and is located in the second horizontal portion 36. As shown in FIG. 6, the inner blade 7 of the first blade part 6 is driven, and the second blade part protrudes from the storage chamber 27, and the movable blade 21 of the second blade part 6 is driven. drive ring 22
It is connected to the driver IO via the driver element IO to reciprocate. Koto,
Through a procedure reverse to that described above, the inner blade 7 of the first blade part 6 is stopped, and the second blade part I is accommodated in the storage chamber 27(8).

[Effects of the Invention] As described above, the electric shaver according to the present invention includes a first blade portion consisting of an outer cutter protruding from a casing and an inner cutter for slidingly contacting the inner surface of the outer cutter; An electric shaver equipped with a second blade section consisting of a flexible comb-shaped fixed blade and a movable blade, characterized in that the second blade section can be freely moved in and out by rotation of the casing. Therefore, the second blade part can be moved out and out of the casing without changing the hand holding the casing, making it easy to use.Furthermore, the operation hand M for moving the second blade part out and out can be protruded from the casing. It has the effect of being able to be shaped without causing any damage, and that it can be used as an easy-to-use electric shaver.
