Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optimum mounting device used when mounting a recording / reproducing device such as a floppy disk device to a mounting portion of information processing equipment or the like.

[0002]

2. Description of the Related Art Conventionally, for example, a floppy disk device as disclosed in Japanese Patent Laid-Open No. 57-36473 is disclosed.
To attach to the information processing equipment such as OA equipment, as shown in FIG. 2, the four screws 42 are attached to the bottom mounting plate 43 of the mounting portion 43.
a through a screw insertion hole 44 provided in a, respectively into the screw holes 45 of the bottom surface 41a of the floppy disk device 41, and each two screws 47 are attached to the left and right side surfaces.
The floppy disk device 41 is screwed to the mounting portion by being screwed into the screw holes 49 of the side surfaces 41b and 41c of the floppy disk device 41 through the screw insertion holes 48 of the plates 43b and 43c.

[0003]

THE INVENTION Problems to be Solved] However, according to the conventional mounting means described above, collected by bottom mounting plate 43a and the side surface
If the attached plates 43b and 43c have a bend or a step,
When the floppy disk device 41 is screwed to the mounting plates 43a to 43c, the frame 50 of the floppy disk device 41 is deformed, such as distorted. Positioning at four points physically on a plane is extremely difficult in terms of accuracy, and in order to maintain accuracy, it is necessary to increase the finishing accuracy of each component, which increases cost. In particular, the recent floppy disk device 41 has become smaller and thinner, and the strength of the frame 50 has been reduced accordingly. Therefore, if the floppy disk device 41 is screwed to the mounting portion 43 in an unreasonable state, the frame 50 is easily deformed.

When the frame 50 is deformed, such as by distortion, a positional deviation occurs between the heads and turntables (neither shown) in the floppy disk device 41, which are positioned with high accuracy. Positional deviation, tracking deviation, etc. have been problems. Further, although a cushioning member such as a rubber bush or a spring is also interposed and attached to each attachment portion, positioning at the time of assembly becomes difficult and the cost increases due to an increase in the number of parts.

Therefore, according to the present invention, when the recording / reproducing apparatus is mounted on the mounting portion by using a screw, the recording is constructed so that the frame of the recording / reproducing apparatus is not deformed due to a bend, a step or the like of the mounting portion. It is intended to provide a mounting device for a playback device.

[0007]

According to the present invention, even if the mounting portion has a bend or a step, the mounting member interposed between the recording / reproducing device and the mounting portion absorbs the bending, the step or the like to perform recording / reproducing. It is possible to prevent deformation such as distortion in the frame of the device. When the mounting member is screwed to the mounting portion , even if the mounting member is deformed by distortion or the like due to bending of the mounting portion or a step, the frame of the recording / reproducing apparatus is screwed to the mounting member at three positions. Therefore, the frame of the recording / reproducing apparatus is unlikely to be affected by deformation such as distortion of the mounting member. Further, since the recording / reproducing device is screwed at three places, the recording / reproducing device is less likely to vibrate (resonate).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a mounting device for a floppy disk device will be described below with reference to the drawings.

First, as shown in FIG. 1, a head (not shown) which is in contact with the recording surface of a rotating floppy disk 6 for recording or reproducing is supported inside the floppy disk device 1. The support device 5 is provided so as to be movable in the arrow a direction. The bottom surface 3a of the frame 3 of the floppy disk device 1 is provided with three screw holes 2 into which the screws 32 are screwed.

Next, the mounting portion 10 to which the floppy disk device 1 is mounted is composed of a bottom mounting plate 10a and side mounting plates 10b and 10c. And bottom mounting plate 1
0a is provided with four screw insertion holes 11
Each of the mounting plates 10b and 10c is provided with two screw insertion holes 14.

Next, the floppy disk device 1 and the mounting portion 1
The mounting member 20 interposed between the mounting member 20 and 0 is made of a substantially rectangular frame body made of metal. And this mounting member 20
Has a rigidity such that when the mounting portion 10 is screwed, the mounting portion 10 is distorted, and the mounting plates 10a to 10c are not deformed easily even if the mounting plates 10a to 10c are bent or stepped.

On the bottom of the mounting member 20, four substantially semicircular projections 21 each having a screw hole 22 are integrally formed, and the upper and left side portions 20b and 20c of the mounting member 20 are also screwed. Four substantially semicircular projections 23 having holes 24 are integrally provided.

The mounting member 20 also has three screw insertion holes 28a, which are burrs corresponding to the three screw holes 2 provided in the bottom surface 3a of the frame 3 of the floppy disk device 1.
~ 28c are provided. Screw insertion holes 28a, 28b
Is an inverted L-shaped projecting piece 27 integrally formed with the mounting member 20.
It is provided on the mounting portions 29a and 29b of a and 27b,
Further, the screw insertion holes 28c are provided on both sides 20 of the mounting member 20.
It is provided on the mounting portion 29c above the raised portion 30a that is raised in a substantially trapezoidal shape of the installed portion 30 that is placed between b and 20c.

Next, a method of mounting the floppy disk device 1 on the mounting portion 10 will be described with reference to FIG.

First, the screws 32 are respectively inserted into the screw insertion holes 28a to 28c of the mounting member 20, and the respective screws 32 are screwed into the screw holes 2 of the floppy disk device 1, and the floppy disk device 1 is mounted at three positions of the mounting members. Parts 29a-2
Screw to 9c. Next, the screw holes 22 of the mounting member 20
The screws 37 and 38 are screwed into the screw holes 24 through the screw insertion holes 11 and 14 provided in the mounting portion 10, and the mounting member 20 is screwed to the mounting portion . As a result, the floppy disk device is fixed to the mounting portion 10.

According to the above-described embodiment, even if the mounting portion 10 is distorted or each of the mounting plates 10a to 10c is bent or stepped, the mounting member 2 screwed to the mounting portion 10 is used.
0 does not undergo significant deformation due to its rigidity. Therefore,
The distortion or the like of the mounting portion 10 is absorbed by the mounting member 20 and hardly affects the frame 3 of the floppy disk device 1,
It is possible to prevent the frame 3 from being deformed such as by the distortion of the mounting portion 10. Even when the mounting member 20 is deformed, the frame 3 of the floppy disk device 1 is
Since it is configured to be screwed to the three mounting portions 29a to 29c of the mounting member 20, even if the mounting portions 20a to 29c are varied in height position due to the deformation of the mounting member 20, those mounting portions 29a to 29c are mounted. The floppy disk device 1 screwed to the portions 29a to 29c has mounting portions 29a to 29c.
The frame 3 which is generated when the floppy disk device 1 is screwed to the mounting member 20 at four points only by changing the mounting posture based on the variation in the height position of the frame 3.
It prevents deformation such as distortion.

The mounting member 20 and four points on the plane of the frame 3
In order to match the four points on the plane formed by the mounting portions 29a to 29c, extremely high accuracy is required. If this accuracy cannot be achieved, screwing for mounting at these four points will When one of them is deformed, the other is also deformed accordingly, and when the frame 3 is distorted, the operation of the floppy disk device 1 is hindered.
Such a problem does not occur when the two planes are made to coincide with each other at a point, and the deformation of one does not cause the distortion of the other.

Further, temporarily, the floppy disk device 1 is attached to the two mounting portions 29a and 29c of the mounting member 20 with the two screws 3.
When the screws are screwed by 2, the floppy disk device 1 is screwed into the screw insertion holes 28 of the two mounting portions 29a and 29c by the internal vibration of the floppy disk device 1 or the vibration from the outside.
Although it is easy to resonate in the direction orthogonal to the line connecting the centers of a and 28c, the floppy disk device 1 is fixed to the three mounting portions 29a, 29b, and 29c of the mounting member 20 by the three screws 32 at three points. The disk device 1 does not resonate in a direction orthogonal to the screwing direction (vertical direction in FIG. 1) such as a direction orthogonal to a line connecting the centers of the two mounting portions 29a and 29c.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and various effective modifications can be made based on the technical idea of the present invention.

For example, in the above-mentioned embodiment, the front side of the frame 3 and the rear side of the frame 3 are fixed to the three mounting portions 29a to 29c of the mounting member 20 with one screw 32 each. However, these three screwing positions may be appropriately determined in consideration of the structure of the floppy disk device 1, the weight balance, and the like.

The present invention is not limited to the mounting device of the floppy disk device shown in the embodiment, but can be applied to the mounting device of various recording / reproducing devices.

[0022]

According to the present invention, since the mounting member is interposed between the recording / reproducing apparatus and the mounting portion , the mounting member absorbs bending, distortion and the like of the mounting portion , It is possible to prevent the frame of the recording / reproducing apparatus from being deformed by distortion or the like due to bending or distortion of the mounting portion .

Since the frame of the recording / reproducing apparatus is constructed so as to be screwed to the mounting member at three places, the mounting member screwed to the mounting portion is distorted due to bending of the mounting portion , a step or the like. Even if the frame of the recording / reproducing apparatus is deformed, distortion of the frame of the recording / reproducing apparatus is prevented.

[0024] Thus, the bending having the mounting portion, by the distortion or the like, subjected to deformation of the frame distortion of the recording and reproducing apparatus attached to the mounting portion, the position of the head displacement on this basis,
It is possible to reliably prevent the occurrence of tracking deviation and the like.

Further, since the frame of the recording / reproducing apparatus is screwed at three points, the recording / reproducing apparatus does not resonate in the direction orthogonal to the screwing direction due to internal vibration or external vibration.
