PROBLEM TO BE SOLVED: To provide a stamp device that has high sealability between a stamped portion of a reversible stamp tool and an ink case, facilitates a stamping operation, and has superior printing stability.SOLUTION: A stamp device that is configured when pressed toward a surface to stamp, to reverse a stamp tool and stamp a seal, comprises: an ink case; and a holder for reversibly holding the stamp tool. The ink case has an opening portion into which a convex stamped portion comprised by the stamp tool and a seal mechanism for sealing a gap between the opening portion and the stamped portion. The seal mechanism has a pair of right and left seal members that when the stamped portion is located in the opening portion, holds the stamped portion from both the sides. The pair of right and left seal members has a biased member acting toward a direction of closing a portion of contacting with the stamped portion and a slidable switch biased toward a direction of closing the seal members in opposition to the biased members, so that when the holder is pressed toward the surface to stamp, the switch retreats, the pair of right and left seal members open, and the stamp tool declines and reverses. |
