DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a device for mounting a drive unit having a disc insertion slot.

"Prior Art" FIG. 4 is a view in which a drive unit 20 having a disc insertion opening 21 is attached to an apparatus main body 50. When installing this
As shown in FIG. 5B, if the disc insertion opening 21 is offset from the center with respect to the opening 36 of the front panel 30, the user may mistakenly think that the device body 50 is out of order. As shown in FIG. 5A, it is necessary to configure these so that the disc insertion opening 21 is located at the center of the opening 36 of the front panel 30.

Therefore, conventionally, the following two means have been taken.

As shown in FIG. 6, the main body of the drive unit 20 is set on the front panel 30 of the apparatus main body 50 with the opening 36 as a reference.
Screw holes are formed in advance, and the back surface of this panel 30
It is attached to 31 with screws 51. As a result, the above-mentioned displacement when the drive unit 20 is attached to the apparatus main body 50 is almost eliminated. However, with such a configuration, the drive unit 20 is cantilevered with respect to the front panel 30, so if the device body 50 is dropped or vibrated by a vibration test, gravity is applied to the drive unit itself, and There is a high risk of the mounting screw breaking or distorting. In order to solve this problem, JP-A-1-
In the 113987 publication, the front end of the drive unit is positioned by the protrusion and the plate is screwed to the lower surface of the rear end,
A technique is disclosed in which this plate is fixed to a chassis via a rubber bush to absorb vibration.

Alternatively, as shown in FIG. 7A, drive unit 20
Attach the bezel 52 of the same color as the front panel 30 to the front of the. Then, the drive unit 20 is attached to the front panel 30 having a large opening as shown in FIG. 7B. Therefore, the opening that the front panel 30 has is sufficiently larger than the opening that the live unit 20 has, and it is configured so that it is difficult to understand even if a deviation actually occurs.

[Problems to be Solved by the Invention] However, the above-mentioned conventional techniques have the following drawbacks.

In the first means, there is a problem that there is an error in the vertical and horizontal dimensions of the front end portion of the drive unit or the arrangement dimensions of the protrusions.

Further, in the second means, an extra member such as a decorative bezel is required, and the front portion is restricted in design because the opening of the front panel is large.

This invention was made in view of such circumstances,
An object of the present invention is to provide a drive unit mounting device that does not require any extra member and that can easily align the disc insertion opening of the drive unit with the opening of the device body and is always correctly positioned without rattling. .

[Means for Solving the Problems] In order to solve the above problems, a drive unit mounting apparatus according to the present invention is provided such that an inclination angle of a front panel surface with respect to a bottom surface of an apparatus body to which the drive unit is mounted forms an acute angle. And a guide member provided on the back surface of the front panel member, the guide unit having a tapered portion for supporting the front end portion of the drive unit on the side having the disc insertion opening by regulating the position from a predetermined direction, and the guide unit. The drive unit is fixed at a position regulated by a member, and a fixing mechanism is provided for supporting the drive unit so as to maintain the posture parallel to the bottom surface of the apparatus body.

[Operation] The front end of the drive unit is positionally regulated and supported by the tapered portion, and the drive unit is fixed so as to maintain a posture parallel to the bottom surface of the apparatus body at the regulated position.

[Embodiment] FIG. 1A is a view for explaining an embodiment of a drive unit mounting apparatus according to the present invention. This mounting device
It has a drive cover and a drive plate 7.

The drive cover has a rectangular upper plate 1, and a right rectangular plate 2 and a left rectangular plate 3 which are rectangular and project downward from the right end and the left end of the upper plate 1, respectively. The depth direction of the upper plate 1 is longer than the depth of the side plates 2 and 3 by a predetermined amount, and the long portion is bent vertically downward to form the folded-back portion 6. Protruding members 6a and 6b are provided at the lower end of the folded-back portion 6 so as to contact the back surfaces of the side plates 2 and 3, and these are spot-welded to the back surfaces of the side plates 2 and 3. On the other hand, on the lower ends of the right side plate 2 and the left side plate 3, there are provided bulging members 4 which bulge outwardly. The bulging members 4 are provided with a drive cover on a chassis 38 (see FIG. 3C) of the apparatus main body. A screw hole 5 is provided so that it can be attached. Note that these drive covers may be integrally molded according to the size of the drive unit 20, or may be configured by bonding individual members (see FIG. 2A). The material of the drive cover is not particularly limited, but it is preferable that the drive cover is made of a metal having sufficient rigidity and a wall thickness of about 0.8 mm to 1 mm.

On the other hand, the drive plate 7 is composed of a rectangular member whose width is substantially equal to that of the upper plate 1 and whose depth is longer than the depths of the side plates 2 and 3 by a predetermined amount. The drive unit 20 is inserted and supported and fixed. As can be seen, the side plates 2 and 3 are horizontally supported at a predetermined height inside, as described later. The material is not particularly limited, but a metal elastic member having a wall thickness of about 0.3 mm to 0.4 mm is preferable so that sufficient springiness can be obtained in the vertical direction. The drive plate 7 is provided with a screw hole 8 capable of supporting and fixing the drive unit 20 and a projecting member 9 at the rear end so as to be horizontally supported.

1B and 1C are views showing an example for supporting the drive plate 7 on the drive cover. Side plate 2,
Each of the 3 is provided with a support member 10 for supporting the drive plate 7. The support member 10 is formed by forming a notch in the side plate by a predetermined amount and curving the side plate inward from the notch. There is. Therefore, the drive plate 7 can be horizontally supported by providing the support members 10 at two places on the side plates 2 and 3 so as to sandwich the drive plate 7, respectively. further,
By performing spot welding of the protruding member 9 to the inside of the folded-back portion 6 at, for example, three places, it is possible to more reliably horizontally support the protruding member 9.

FIG. 2A shows the drive unit 20 and the drive plate 7
It is a figure showing the state where it was attached to a drive cover.
A mounting screw hole (not shown) is provided on the lower surface of the drive unit 20 so that the front end of the drive unit 20 can be extended and fixed from the drive cover, and through the screw hole 8 shown in FIG. 1A, The drive unit 20 is fixed and supported on the drive plate 7 by screwing the fixing screw into the mounting screw hole.

An embodiment of the present invention will be described with reference to FIGS. 3A to 3C. As shown in FIG. 3A, the device is installed so as not to be displaced with respect to the disk insertion opening 21 of the fixed and supported drive unit 20. A pre-positioned opening 36 is formed in the front panel 30 of the main body, and the floppy disk
40 is inserted in the direction of the arrow in the figure. Further, the front panel 30 (front panel member) is provided with an inclined surface such that the inclination angle of the front panel surface with respect to the bottom surface (chassis 38) of the apparatus body forms an acute angle.

On the other hand, on the back surface 31 of the front panel 30 of the main body of the apparatus, the front end of the drive unit 20 is positionally regulated from a predetermined direction (in this example, vertically regulated and laterally regulated), and is supported. Drive guides 32, 33, 34, 35 that are tapered are provided so as to easily enter (see FIGS. 3A to 3C). Then, the front end portion is pressed down by taper, and the drive unit 20 is fixed to the chassis 38 of the apparatus body by a fixing mechanism such as a drive cover so as to maintain the posture parallel to the bottom surface of the apparatus body. As a result, it is easy to align the disc insertion opening 21 of the drive unit 20 with the opening 36 of the apparatus main body, and even if there are some errors in the vertical and horizontal dimensions of the front end of the drive unit and the arrangement dimensions of the protrusions, the tapered portion The disk insertion opening 21 of the drive unit 20 will not be displaced with respect to the opening 36 of the apparatus main body. Further, since the drive plate 7 has a spring property in the vertical direction, when the drive unit 20 is inserted and assembled, even if there is some rattling in the vertical direction, it is absorbed and displacement is prevented. Therefore, it is possible to effectively absorb the vibration of the device body. Similarly,
With respect to rattling in the left-right direction and the back-and-forth direction, by increasing the diameter of the screw hole 5, the drive cover can be slightly moved in the left-right direction and the back-and-forth direction to be fixed to the chassis 38 and absorbed. Further, since the drive unit 20 is supported so as to maintain the posture parallel to the bottom surface of the device body even if the front panel 30 is inclined, an efficient mounting layout can be secured in the device body.

Further, by making both the drive case and the drive plate 7 metallic, the drive unit 20
Eliminates the need for a shield case. As a result, when the drive unit 20 is inserted and assembled, the drive plate 7
Due to the springiness of the drive unit 20, the entire upper surface of the drive unit 20 comes into contact with the upper plate 1, and even the portion which should not be brought into contact with the upper plate 1. Therefore, in this case, in four places on the upper plate 1,
As shown in FIG. 2B, a recess 11 is provided at a position where the upper surface of the drive unit 20 does not interfere with the contact.

[Advantage of Invention] Since the front end of the drive unit is supported by being regulated in a predetermined direction by the guide member having the tapered portion, it is easy to align the disc insertion opening of the drive unit with the opening of the apparatus body. At the same time, it is possible to prevent misalignment without causing rattling. Further, since the drive unit is supported so as to maintain the posture parallel to the bottom surface of the device body even if the front panel member is inclined, an efficient mounting layout can be secured in the device body. Further, since no extra member is used, it is not necessary to make a large opening in the front panel, and the front part of the apparatus body is not restricted in design.
