However, in the above-mentioned conventional example, the outer blade cartridge alone has a coupling structure capable of being detached from the outer blade holder when the outer blade is attached to the main body case. Therefore, when cleaning the shavings or exchanging the outer blade, when you grab the outer blade holder by hand and remove it from the main body case, the outer blade holder may remain in the main body case due to slipping of your hands on the outer blade holder. There was a problem that only the outer blade cartridge came off, or the outer blade holder came off and the outer blade cartridge came off from the outer blade holder at the same time. Further, when the outer blade cartridge comes off from the outer blade holder at the same time as the outer blade holder comes off, there is a possibility that the outer blade cartridge may be dropped by the momentum and damaged.

Now, with the outer blade 39 mounted on the main body case 1, as shown in FIG. 10, when the finger hook portion 49 of the unlocking operation knob 47 is put on by a hand and pushed inward, this knob is pushed. Although the engaging element 52 is pushed against the spring 51 by the pressing action of 47 and disengages from the recessed portion 50, the engaging portion 46 of the unlocking operation knob 47 abuts the knob movement restricting means 54 on the main body case 1 side, so that the lock operation The release operation knob 47 is restricted from shifting in the direction in which the engaging portion 46 is disengaged from the engaged portion 45. Therefore, at this time, the outer blade holder 44 together with the outer blade cartridge 40 can be removed upward from the main body case 1, but the outer blade cartridge 40 does not come off from the outer blade holder 44. When the outer blade holder 44 is detached from the main body case 1, as shown in FIG.
Since the engaging portion 46 of the unlocking operation knob 47 can be disengaged from the engaged portion 45 of the outer blade cartridge 40 by putting a hand on the finger hanging portion 49 of 7 and pushing it inwardly, The blade cartridge 40 can be detached upward from the outer blade holder 44.

In FIG. 12, the safety switch 58 includes a spring 65 from a part of the body case 1 at the lower end of the holder 44 when the outer blade holder 44 is mounted in the body case 1.
The switch operation piece 64 protruding by the biasing force of the
7 and the intermediate terminal plate 59 are closed, but the outer blade holder 44
When is removed from the main body case 1, the pressing action on the switch operation piece 64 by this is released, so that the power supply circuit is opened. Therefore, when the outer blade holder 44 is removed for cleaning dust etc., the rotating inner blade 3 does not rotate carelessly, which is safe. Also,
If only the outer blade cartridge 40 is detached from the main body case 1, the safety switch 58 remains turned on, so that the rotating inner blade 3 is rotated and there is a risk. However, in the above-described embodiment, the outer blade cartridge 40 alone is detached. Since it is impossible to do so, safety can be secured without any such danger.

In the above embodiment, one unlocking operation knob 47 serves to disengage the concave portion 50 of the outer blade holder 44 from the engaging element 52 on the main body case 1 side and the engaged portion 45 of the outer blade cartridge 40 to the outer blade holder. Although it has the function of disengaging from the engaging portion 46 of 44, in place of this, it is separate from the lock releasing operation knob 47 for disengaging the recess 50 of the outer blade holder 44 from the engaging element 52 on the main body case 1 side. , The engaged portion 45 of the outer blade cartridge 40 and the engaging portion 4 of the outer blade holder 44.
It is also possible to provide a lock release operation knob dedicated to this for releasing the engagement with 6. Further, the lock releasing operation knob 47 for releasing the engagement between the engaged portion 45 of the outer blade cartridge 40 and the engaging portion 46 of the outer blade holder 44 is provided on the outer blade holder 44 side instead of being provided on the outer blade cartridge 40 side. Can also be provided. Of course, in addition to the rotary type electric shaver, the above-mentioned conventional reciprocating electric shaver can be similarly applied, and two or more of the rotary inner blades or the reciprocating inner blades may be arranged in parallel. Needless to say.
