2. Description of the Related Art A conventional replacement blade feeder for a razor replacement blade, which stores the replacement blades so that their side surfaces contact each other, stores the replacement blades without a back metal. It was limited to things.

[0003]

Since the conventional spare blade supply device as described above is limited to one that stores a spare blade without a backing, a plurality of spare blades with a backing are added to this conventional product. When stored, the thickness of the side with the back metal is large, so that there is a problem that the stacked spare blades are inclined. Therefore, when storing a spare blade with a back metal, it is necessary to stack the back blade of the spare blade and the edge of the blade so that they are staggered one by one. When mounting, the first blade can be inserted into the holder as it is, but the back blade and the blade edge of the second blade are reversed, so the replacement blade feeder must be inverted. In this case, inconvenience occurs. It is an object of the present invention to provide a spare blade feeder that can store a plurality of spare blades with back spines in a stacked manner without causing such an inconvenience, and can smoothly mount the spare blades on a holder. And

According to the present invention, a back metal 1 is provided.
A razor replacement blade feeder for storing a plurality of razor replacement blades 2 with a blade and supplying the razor replacement blades 2 to the holder-3, wherein each of the plurality of replacement blades 2 has a back metal 1 and a blade edge 6 staggered. When the replacement blades pressed in the outermost part of the stacked replacement blades are moved in their length direction, Two narrow outlet holes 7 and 7 are provided at both ends of the storage part so that the blade can be pulled out of the storage part in any direction, and it is pressed at the outermost side. It is characterized by having means for moving the replaceable blade in one direction.

The further embodied structure of the present invention is a razor replacement blade feeder 4 for accommodating the razor replacement blade 2 with the back metal 1 and supplying the razor replacement blade 2 to the holder-3. Two
The blades are stored so that the back metal 1 and the blade edge 6 of each blade 2 are alternately stored, and all the stored blades are always An elastic member for elastically pressing in the direction of the replacement blade superimposed on the top is provided in the storage portion 5, and when the topmost replacement blade is moved in the length direction, any one of its both ends is used. A pair of narrow outlet holes 7, 7 are provided at the upper ends of both ends of the storage portion so that the blade can be pushed out of the storage portion also from the direction. A moving body 8 is slidably mounted in a longitudinal direction, and a replacement blade pushing projection 9 provided on the sliding body 8 has a guide hole 1 extending in a longitudinal direction in an upper portion 10 of the replacement blade supply device.
When the sliding body 8 is placed at both ends of the movable range of the sliding body 8 by pressing the side surface of the uppermost replacement blade 2 projecting into the storage section 5 through the first storage section 5, It is provided on the sliding body 8 so as to be located outside the end of the spare blade and the pressing state on the spare blade is released, and from the position of one end of the movable range of the sliding body 8 When the uppermost replacement blade 2 is slid and pushed out from the outlet hole 7, the replacement blade pushing protrusion 9 is locked so as to be locked only to the end of the topmost replacement blade. The blade pushing projection 9 protrudes from the sliding body 8.

[0006]

Embodiments of the present invention will now be described with reference to the drawings. The spare blade 2 has a back metal 1 attached thereto, and in the present invention, a plurality of such spare blades 2 are stacked and stored. The blade replacement device 4 is made of synthetic resin and has a rectangular blade storage portion 5. The spare blade 2 has a backing metal 1 and a blade edge 6 in the storage portion 5.
The blades are stacked and stored so that they are staggered, so that the plurality of spare blades stacked and stored do not tilt in the storage portion.

[0007] The chevron leaf spring 12 is mounted between the bottom of the storage portion and the support plate 19 under the lowermost blade in the stacked blades. Is constantly pressed upward. A pair of narrow outlets are provided at the upper ends of both end portions 13 of the storage portion so that the uppermost replacement blade 2 of the stacked replacement blades can be pushed out of the storage portion 5 from either direction of the both ends. Holes 7, 7 are provided. The shape of the outlet hole 7 has a width and a height just enough for a single blade 2 with a back metal to pass through.

The upper portion 10 of the spare blade feeder is extended so as to extend outside the end portions 13 of the accommodating portion. That is, the blade supplying device 4 has a shape in which the thin plate portions 16 are integrally protruded from both ends of the upper portion thereof. An elongated guide hole 11 is provided in the central longitudinal direction of the upper portion 10 so that the replacement blade pushing protrusion 9 for pushing the replacement blade 2 can move when the sliding body 8 slides. . Both ends of this guide hole 11 are both end portions 13, 1 of the storage portion.
3, but does not reach the ends of the thin plate portions 16, 16. Therefore, when the sliding body 8 is moved, the replacement blade pushing projection 9 that moves in the guide hole 11 in the longitudinal direction hits the end of the guide hole 11 and the movement of the sliding body is restricted. Determines the slidable range of the sliding body. Above both lateral portions 14 of the storage portion, grooves 15 are provided in the longitudinal direction, respectively. The grooves 15 are for guiding the sliding of the sliding body 8.

The sliding member 8 is integrally formed of a synthetic resin, and has a substantially U-shaped end portion, and is mounted on the upper surface thereof so as to straddle the blade supplying device 4 from above. That is, the side plate portions 17 of the sliding member are connected to the side portion 1 of the blade supplying device.
4, 14 extending downward so as to be circumscribed by the side plate portions 17, 1
When the projections 18, 18 provided integrally on the inner surface of the lower end of 7 engage with the grooves 15, 15, the sliding body 8 is slidably mounted on the blade supplying device 4.

A spare blade push-out projection 9 is integrally provided on the back surface of the sliding body 8, passes through the guide hole 11 and projects slightly into the storage section 5. When the sliding body 8 is located near the center of the spare blade supply device, the spare blade pushing projection 9 presses the spare blade 2 therebelow from above. When the blade is slid to the portion, the blade pushing protrusion 9 moves to the outside of the end of the blade that has been pressed, and the pressed state is released. The uppermost replacement blade 2 that has been released from the pressed state is brought into pressure contact with the ceiling surface inside the storage portion 5, and the replacement blade pushing projection 9 is located immediately next to the end of the replacement blade 2. The replacement blade push-out projection 9 projects only so as to be locked only at the end of the uppermost replacement blade pressed against the ceiling surface in the storage portion 5, and is the second replacement blade from the top. Does not reach the end of the.

After the sliding body 8 is slid to one end of the slidable range and then the sliding body 8 is slid toward the other end, the blade extruding projection 9 is moved to the top. By pushing the end of the spare blade 2, the spare blade 2 is pushed out from the outlet hole 7, so that the spare blade can be inserted into the holder 3 as it is. When the sliding body 8 is moved to the other slidable end and the uppermost spare blade is attached to the holder-3, the second superimposed spare blade is placed on the ceiling in the storage unit 5. Since the sliding member 8 is slid in the direction opposite to the previous direction by the same operation as when the first spare blade is pushed out, the second spare blade is pushed out from the other outlet hole 7 because it is pressed against the surface. Therefore, it can be directly inserted into the holder-3.

In this way, the spare blade is pushed out even if the sliding body 8 is slid in any direction. Therefore, the spare blade with the back metal is alternately provided by the back metal 1 and the blade edge 6 one by one. If the blades are stored in the storage part 5 in such a manner that the blades are superimposed on each other, the blades are always supplied to the holder in the same state only by reversing both ends of the blade supply device 4.

[0013]

As described above, according to the present invention, a plurality of spare blades 2 are stacked and stored such that the back metal 1 and the blade edge 6 are alternately staggered and elastically pressed. When the spare blade stored in the part 5 and pressed against the outermost of the stacked spare blades moves in the length direction,
Two narrow exit holes 7, 7 are provided at both ends of the storage section so that the blade can be moved out of the storage section regardless of the direction in which the blade moves. Means for moving the replacement blade in one direction. Therefore, there is no possibility that the plurality of superposed blades are inclined in the storage unit 5. Further, even if a plurality of replacement blades 2 are stored in a state where the back metal 1 and the blade edge 6 are alternately stacked for each sheet, if the replacement blades 2 are alternately put out from the two outlet holes 7, 7. By simply reversing the blade supply device 4, the blade can always be supplied to the holder 3 in the same state.
