Abstract: A hand stamp is set forth which allows normal stamping of a signature and allows a matrix plate thereof to be reversed when not in use in order to prevent abrasion of the matrix. This hand stamp includes a first member having an n-shaped structure and a handle integrally formed on the n-shaped structure with the n-shaped structure defining a first internal space. A plurality of guides are placed respectively on an inside of a first pair of sidewalls of the n-shaped structure. A second member is movably received within the space of the first member with the second member defining hog portions at appropriate positions. A substantially rectangular plate with a slightly smaller area than the cross-sectional area of the second member is received within a second internal space of the second member with the rectangular plate having two bosses respectively defined on a pair of wing surfaces extending from the rectangular plate and being rotatably received within the hog portions of the second member.

Abstract: A roller stamp device includes a housing which is open at a lower side thereof, a front wheel assembly, a rear wheel assembly mounted to a rear portion of the housing, and an ink pad assembly. The front wheel assembly includes a wheel mounted on a front wheel axle which, in turn, is rotatably mounted to a front portion of the housing and a stamping strip placed around and secured to the periphery of the wheel. The ink pad assembly includes at least one ink pad mounted around an ink pad axle, which, in turn, is mounted to a middle portion of the housing. The ink pad axle includes a first axle section and a second axle section which are separably engaged together. The roller stamp device further has a U-shaped bumper to rotationally mount the front wheel axle and the ink pad axle to the housing.

Abstract: A stamp has a housing and a stem provided on the housing. A lid is provided on the stem. A holder is connected to the lid by a rod and is receivable in the housing. A number of grooves are formed in a bottom of a lower casing. An upper casing and the lower casing are insertable into the holder. A number of blocks each has a letter, a numeral or a symbol carved on a lower surface. The blocks are disposed and arranged in the grooves. When the lid is pressed downward, the blocks are caused to move downward to stamp a surface to be stamped.
