Abstract

Provided is a rotary stamp capable of obtaining an imprint having a uniform density. The rotary stamp includes a sheathing (300) covering an outer side of an upper portion of a leg frame body (1), with a spring (5) interposed therebetween, and being movable upward and downward; and a signet body (2) being movable together with the sheathing (300) and being movable upward and downward with respect to the leg frame body (1). When the sheathing (300) is caused to move downward by exerting a pressing force on the sheathing (300), a stamping face of the signet body (2) makes a half turn and advances to a position where the stamping face is brought into contact with a sealing position. When the sheathing (300) is caused to move upward by releasing the pressing force from the sheathing, the stamping face of the signet body (2) makes an inverse half turn and retracts into the leg frame body (1) to be brought into contact with a vermilion seal ink pad (400) incorporated into the leg frame body (1), in a state where the stamping face is pressed thereagainst. The rotary stamp includes a vermilion seal ink pad rotating mechanism operable to cause the vermilion seal ink pad (400) to rotate by a predetermined angle on a plane orthogonal to a direction in which the signet body (2) advances and retracts, along with upward and downward movements of the sheathing (300) during sealing operation.
