IPC: B29C45/36
Filed: 1988-09-28
Abstract: PURPOSE:To decrease the product inferiority due to the dust and foreign matter entering a gap by a method wherein a stamper is attached to a movable mirror block with no clearance between them regardless of the fluctuation in the thickness of the stamper. CONSTITUTION:A stamper 2 is fixed to a movable mirror block 3 by means of an inner stamper holder 4, to which spring mechanism is given, with nuts 10. The inner stamper holder 4 is made of phosphor bronze or spring steel so as to give springiness to its claw part 11, by which the stamper 2 is held down. Further, the claw part 11 has a shape bent towards the stamper so as to be elastic by 0.03mm in order to absorb the fluctuation of 0.02mm in the thickness of the stamper. As a result, the stamper can be attached to the movable mirror block 3 with no clearance between the stamper 2 and the inner stamper holder 4, even when either a thinner stamper or a thicker stamper, the thickness of which lies within the range of allowable fluctuation, is attached. Furthermore, since the clamping force developed by nuts 10 is borne by a part (a), no excess force is applied to the claw part.
