PROBLEM TO BE SOLVED: To provide a structural device which enables sure positional shift of an outer periphery pressing ring in order to prevent a trouble from occurring in a positional state in which positional movement of the ring to an engagement member is not made certainly, and easily confirms the positional movement visually. SOLUTION: This stamper replacement device fixes a stamper 16 with a mirror plate 14 or removes the stamper 16 from its fixed state directly or indirectly, by the movement of oblong hole positions 41, 42, 43 following the shift of an outer periphery holding ring 30. The positional shift of the outer periphery holding ring 30 is structurally performed by a freely releasable handle 70. The handle 70 has a collar part 75 and a slip-off stopper member 90 which prevents the collar part 75 from receding halfway through the shift of the handle 70 is provided on the die side. Besides the device is structured so that the removal of the handle 70 is disabled at an intermediate position N other than a position where the outer periphery holding ring 30 is engaged with or disengaged with engagement members 51-53. |
