Title: Disk device
Inventor: KOIZUMI SHIGEKI
IPC: G11B17/028
Filed: 1991-02-14
Abstract: PURPOSE:To easily make the disk device thin and to prevent a driving pin from being inclined in the case of chucking by using a driving pin arm provided with an elastic part between a pivotally supporting part and a position regulating part. CONSTITUTION:When a driving pin 24 is moved to a position C', a position regulating hole 22c is slid to a prescribed position in a direction D along a half blanking boss 20a and since it is further pulled in the direction D, however, a weak spring part 22b of the pin 24 is warped. Force caused by this warp is transmitted as the rotating force of an arm 22 and operated as force to return the pin 24 to a position C. Therefore, force is operated to energize the pin 24 in a direction F4, and centering force is forced to set a spindle 5 at the center of a magnetic disk with respect to a center hub in the state of not inclining the pin 24. Further, by providing a hole 22a, the arm 22 can be easily bent.

Filed: 1989-01-31
Abstract: PURPOSE:To diminish the dust sticking to various kinds of optical parts such as an objective lens, etc., by setting up a transparent plate for preventing the dust from infiltrating into an actuator unit between the objective lens and an optical information recording medium. CONSTITUTION:The transparent plate 21 for preventing the dust from infiltrating into the actuator unit 3 is set up between the objective lens 15 and the optical information medium.
