2. Description of the Related Art Conventionally, as a cartridge type razor of this type, a cartridge type razor is known in which a pair of cartridges are replaceably attached to a head portion provided at the tip of a holder. That is, the holder is provided with a head portion extending forward from its front end, and mounting grooves are formed on both sides of the head portion over the entire length direction. On the other hand, the cartridge is provided with a claw-like attachment portion on its back side, and the cartridge is attached by inserting this attachment portion into the attachment groove.

[0003] Furthermore, in the cartridge, a lower blade body and an upper blade body are sandwiched between a blade stand and a top plate via a spacer, and a dregs removing plate is movable in the front and rear direction between the upper and lower blade bodies. At the same time, a push operation section for operating the dandruff removal plate is provided protruding from the rear end edge of the dandruff removal plate, and when this cartridge is attached to the head section, the push operation section protrudes substantially parallel to the side surface of the head and remains at a lower position than the upper end of the head.

However, in the above-mentioned conventional cartridge type razor, when trying to press the pressing operation part of the dandruff removing plate with the cartridge attached to the head part, the finger touches the head part first. Because it hits the button, it is not possible to press the pressing operation section easily.

[0005] Therefore, when pressing the pressing operation section,
There is a problem in that removing beard dregs is very troublesome because the cartridge must be pressed with a fingernail or the like or after the cartridge has been removed from the head. The present invention has been made in view of the above-mentioned circumstances, and its object is to use a cartridge type that can easily remove beard dregs from a cartridge by making it easier to move and operate a dandruff removal plate. Our goal is to provide leather.

[0006]

[Means for Solving the Problems] In order to achieve the above object, in the present invention, a head portion is provided at the tip of the holder, and the head portion has a dandruff removing plate on at least one of both sides thereof. A cartridge is attached to the holder, and the cartridge is equipped with a pressing operation part provided on the rear edge of the dandruff removal plate, and the holder is equipped with an external operation member that moves between a pressing position where the pressing operation part is pressed and a retracted position where the pressing operation part is not pressed. The gist is that a possible pressing means is provided.

[0007]

[Function] According to the above structure, the pressing means can operate the pressing position where the pressing operation part is pressed and the retracted position where it is not pressed, so that when the pressing means is moved to the pressing position, the dandruff removing plate removes beard dregs. By pushing out and moving the pressing means to the retracted position, it is ready for use.

A protrusion 10 is inserted into the groove 4 of the holder 1. The head portion 8 is fixed to the holder 1 by inserting the screw 5 screwed into the hole 6 of the protrusion 3 into the insertion hole 10a provided in the protrusion 10.

As shown in FIGS. 1, 2 and 6, the slide member 11 serving as the pressing means is made of elastic synthetic resin and has a semi-cylindrical shape as a whole. A non-slip portion 12 is formed on the upper surface of the slide member 11, and flat pressing surfaces 11a are formed on the lower surface of both ends.
A pair of locking protrusions 13 are provided on the inner surface of the holder 1 so as to correspond to the guide grooves 7 of the holder 1 . Then, by widening the lower opening end against the elasticity of the main body of the slide member 11, the locking protrusion 13 is fitted into the guide groove 7, and the slide member 11 is supported movably along the guide groove 7. There is.

As shown in FIG. 7, the cartridge 14 includes:
It consists of a blade stand 15, a lower blade body 16, a spacer 17, an upper blade body 18, a top plate 19, and a dreg removal plate 20, and the lower blade body 16, spacer 17, and upper blade body 18 are placed on the blade stand 15 in this order. The caulking protrusions 19 protrude from the top plate 19.
It is sandwiched between the blade stand 15 and the top plate 19 at the point a. The dandruff removal plate 20 has a frame shape with a front frame part 21, a rear frame part 22, and left and right side frame parts 23, and has a pressing operation part 22a protruding rearward from the center of the rear frame part 22 and a front frame part. A connecting portion 24 is formed between the connecting portion 21 and the central portion of the connecting portion 21.
A movement permissible space 25 is formed on both the left and right sides. This dandruff removal plate 20 has a pair of left and right spacers 17 loosely fitted in its both movement permissible spaces 25, and the upper and lower blade bodies 16
, 18 so as to be movable in the front and rear directions. Stopper portions (not shown) are formed at the four corners of the lower surface of the top plate 19, and both front and rear ends 23a and 23b of the left and right side frame portions 23 of the beard dwarf removal plate 20 are latched to the stopper portions.
The dandruff removing plate 20 is movable between the front and rear stopper portions.

A pair of leaf spring portions 26 in the shape of a cantilever extend rearward from the front frame portion 21 on both the left and right sides of the connecting portion 24, and extend through the opposing separation ends 17a of the pair of spacers 17, so that both plates are connected to each other. The spring portion 26 is curved to both left and right sides so as to engage with the separation end portion 17a. The curved portions of both leaf spring portions 26 are locked to the rear end sides of the opposing separation ends 17a of the pair of spacers 17, and the dandruff removal plate 20
