Abstract
Abstract A razor in which a razor blade and a blade support, on which the razor blade is mounted, move together back and forth with respect to the base of the razor so as to adjust the contacting angle with respect to the operator's skin. The base is provided on the top of the handle of the razor, and the razor blade and the blade support are covered by a top plate mounted on the base. Provided in front of the blade support is a guard member which projects forwardly beyond the cutting edge of the razor blade and extends parallel with the cutting edge. The blade support and the razor blade are moved back and forth by a rotatable operating member. When the blade support is retracted backwards, the whisker particles clinging to the blade are scraped off and dropped from between the base and the guard member.

Claim 3
Dependent Claim
47 words
A razor as set forth in claim 1, wherein said knob of the operating member has a projection that slides on a curved wall formed on the rear side of the top plate and which selectively registers with one of the notches formed on the curved wall.
Claim 4
Dependent Claim
53 words
A razor as set forth in claim 1, wherein said support shaft of the operating member has a guide portion for stabilizing the rotary movement of the operating member, said guide portion being disposed within a depressed portion for sliding movement along the inner wall of the depressed portion formed in the base.
Claim 5
Dependent Claim
59 words
A razor as set forth in claim 1, wherein said guard member is provided in front of the blade support and connected thereto through a plurality of arms so that at least one exhaust hole to drop whisker particles is formed by the inner surface of the guard member, the front surface of the blade support and the arms.
Claim 6
Dependent Claim
37 words
A razor as set forth in claim 4, wherein at least one of the inner surface of the guard member and the front surface of the base has a notch for facilitating the dropping of whisker particles.
Claim 7
Dependent Claim
65 words
A razor as set forth in claim 4, wherein said base has a front frame on its front portion which passes through the exhaust hole to bear against the underside of the razor blade so that when the blade support moves backwards the whisker particles clinging to the razor blade can be scraped off by the front frame and be dropped through the exhaust hole.
Claim 8
Dependent Claim
51 words
A razor as set forth in claim 1, wherein said attaching means for fixing the top plate to the base comprises a pair of grooves formed on the base on both sides and a pair of claws projecting downwardly from both ends of the top plate for engagement with said grooves.
Claim 9
Dependent Claim
56 words
A razor as set forth in claim 1, wherein said blade support and said base have a pair of grooves and a pair of guide rails respectively on their opposing surfaces, said guide rails and grooves extending along the direction of the movement of the blade support and being adapted for sliding engagement with each other.
Claim 10
Dependent Claim
28 words
A razor as set forth in claim 8, wherein one of said pair of guide rails has a rectangular cross section and the other a trapezoidal cross section.
