Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a motor mounting device for mounting a disk drive motor to an internal chassis.

(b) Conventional technology Conventionally, the installation of a disk drive motor (hereinafter referred to as a spindle motor) was carried out, for example, in 1983-
It is publicly known in Publication No. 85738 (G11B17/028). In such a prior art, as shown in FIGS. 3 and 4, the spindle motor 1 has a motor shaft 2 inserted into the through hole 4 of the chassis 3, and screws 5, 5 are inserted into the chassis 3.
After that, the turntable 6 is press-fitted or screwed onto the motor shaft 2 and attached to the motor shaft. However, in such a conventional device, when the spindle motor 1 breaks down and the spindle motor 1 is to be removed, the turntable 6 must be removed one by one, which is very troublesome and also causes installation errors when the turntable 6 is installed. I feared that something would happen.

(c) Problems to be Solved by the Invention The present invention aims to provide a motor mounting device that does not require the turntable to be removed when the spindle motor is removed.

(d) Means for Solving the Problems In order to provide the above-mentioned device, the present invention provides a motor mounting device in which a disk drive motor to which a turntable for mounting a disk is pivotally attached is screwed to an internal chassis. The inner chassis is provided with a notch that extends from the edge of the chassis to the rotating shaft of the motor, and the turntable is provided with a through hole at a position substantially opposite to the mounting screw, and the jig is inserted through the through hole. This allows the mounting screw to turn.

(E) Function When removing the motor, insert a jig into the through hole of the turntable and turn the mounting screw. After removing the screw, move the motor to the open side of the notch, and the motor will be removed from the edge of the internal chassis. can be removed.

(f) Examples Examples of the present invention will be described below. Incidentally, the same parts as in FIGS. 3 and 4 used in the conventional example are given the same reference numerals, and explanations thereof will be omitted.

An opening 7 is provided in the center of the chassis 3, and a notch 8 is further provided at a position extending from the edge of the opening 7 to the motor shaft 2. Further, the turntable 6 is provided with through holes 9, 9 at positions facing the screws 5, 5 screwed onto the chassis 3. 10 is a pickup; 11, 11 is a shaft that supports the pickup 10;

Now, for example, when the spindle motor 1 breaks down and is to be removed from the chassis 3, insert a screwdriver (not shown) into the through holes 9, 9, loosen the screws 5, 5, and remove the screws 5, 5 from the chassis 3. When the spindle motor 1 is moved toward the opening 7, the motor shaft 2 is removed from the chassis 3, and the spindle motor 1 and turntable 6 can be removed together. Spindle motor 1 again
If you want to attach it to the chassis 3, just follow the above steps in reverse.

As described above, in this embodiment, when removing the motor, the turntable can be easily removed from the chassis without having to remove the turntable each time.

Note that the present invention is not limited to the above embodiments. For example, in addition to the notch, a screw 5 is inserted from the opening 7,
If a notch reaching 5 is provided, the spindle motor 1 can be removed simply by loosening the screws 5, 5. Further, the turntable 6 may have only one through hole 9, 9, and in this case, after removing one screw, the turntable is rotated and the through hole is placed at a position opposite to the other screw. After that, loosen the remaining screws again using a screwdriver.

(g) Effects of the invention According to the invention, since it is not necessary to remove the turntable each time the motor is removed, work efficiency is improved and there is no risk of installation errors caused by attaching and detaching the turntable as in the prior art.
