Patent ID: 8336455

Claim:
A rotary stamp comprising: 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 ), the rotary stamp operable to perform sealing by positioning a lower end of the leg frame body ( 1 ) at a position where a seal is put and by moving the sheathing ( 300 ) downward, wherein 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; and 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, and the rotary stamp comprises 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.
