Abstract
There are provided with a first supporting unit 12 which supports a disk substrate 11, a second supporting unit 14 which supports a stamper 13, a pressing member 15 which applies a pressing force on the disk substrate 11 and the stamper 13, and a fore-contact preventing member 17 which abuts against a peripheral area of the stamper 13 to maintain a not-yet-contacted area in a suspended posture, wherein the stamper 13 which is maintained in such posture is pressed by the pressing member 15, whereby the stamper is stamped on the disk substrate.
Claims7
A stamping apparatus, which is provided with a first supporting unit which supports a first plate-like member;
- a second supporting unit which supports a second plate-like member for stamping on the first plate-like member, and is disposed above the first plate-like member;
- and a pressing member which applies a pressing force on the first and the second plate-like members to perform stamping;
- comprising:
- a fore-contact preventing member for forming a not-yet-contacted area by abutting against a peripheral area of either the first plate-like member or the second plate-like member;
- wherein
- the pressing member applies the pressing force from the opposite side of the abutted position by the fore-contact preventing member to perform stamping of the first plate-like member with the second plate-like member.
A stamping method, which includes stamping of a first plate-like member with a second plate-like member by applying a pressing force on the first and the second plate-like members in a state of their faying surfaces, comprising:
- forming a not-yet-contacted area by abutting against a peripheral area of either the first plate-like member or the second plate-like member;
- and
- applying the pressing force from the opposite side of the abutted position thereby removing air from between the first plate-like member and the second plate-like member.
