Title:
MOUNTING STRUCTURE OF OPTICAL PARTS FOR ADJUSTMENT AND MAGNETO-OPTICAL DISK DEVICE
Document Type and Number:
Japanese Patent JP3837752
Kind Code:
B2
Abstract:

PURPOSE: To prevent the fluctuation of a multilens barrel from a mounting adjustment position by a temp. change by bringing this lens barrel into pressurized contact with the required two surfaces of the base of the lens barrel by means of shielding springs and mounting the lens barrel in this state at the mounting position via an adhesive.
CONSTITUTION: The multilens barrel 22 is brought into pressurized contact with the two surface positions M, N of the base 31 by means of the shielding springs 36 and is held in the state that the mounting position is adjusted at the mounting position C of the base 31. The lens barrel 22 is fixed in this state at the position C between the positions M and N via the adhesive 38. Then, if the adhesive 38 is extended by the temp. change, the extension force acts on the lens barrel 22 toward the direction opposite to the elastic repulsion direction of the springs 36. Consequently, the fluctuation of the lens barrel 22 from the adjustment position by the temp. change is prevented and the characteristics of the optical system are stabilized.
