BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disk device mounting adapter for holding an outer casing of a disk device for mounting and connecting the disk device to various devices.

[0002]

2. Description of the Related Art Conventionally, there has been proposed a disk device for writing and / or reading an information signal to / from a disk which is a recording medium for an information signal such as a magnetic disk, an optical disk or a magneto-optical disk.

This disk drive is a rotary drive mechanism for rotating the disk, or a magnetic or optical system for writing and / or reading an information signal to and from the disk which is rotated by the rotary drive mechanism. Head device and the like, and these are housed in an outer casing.

By the way, various disks having various diameters have been proposed. That is, as this disc, a disc having a diameter of, for example, 2.5 inches, 3.5 inches, 5 inches, or 8 inches is proposed. In the disk device, the size of the outer casing is determined according to the diameter of the disk used as the recording medium.

Conventionally, a small disc having a diameter of, for example, 3.5 inches is used, and a disc having a diameter larger than that of the small disc, for example, a diameter of 5 inches is used. There has been proposed a disk device mounting adapter for mounting in place of a large disk device configured as described above.

That is, the size of the outer casing is different between the small-sized disc and the large-sized disc device, and the position and structure of the electrical connector portion provided on the rear surface portion of the outer casing are different. Therefore, there is no compatibility with various external devices such as so-called computer devices and word processor devices to which these disk devices are attached or connected and used. The mounting adapter of the disk device is attached to the outer casing of the small disk to give the small disk compatibility with the large disk device.

The mounting adapter of the disk device has a pair of frames mounted on both sides of the outer casing of the small disk. These frames are attached to both sides of the outer casing of the small-sized disc so that the distance between the outer side faces of each of the smaller discs becomes equal to the distance between the outer face portions of the outer casing of the large disc device. Has been done. Further, the size of these frames in the height direction is made equal to the height of the outer casing of the large-sized disk device.

The mounting adapter of the disk device has an electric circuit board which is inserted between the frames and supported by the frames.

By the way, as the above-mentioned small-sized disc, even if the outer casing has the same size,
There are used a plurality of models designed such that the positions and shapes of the connector portions are different from each other. Therefore, in the disk device mounting adapter as described above, it is necessary to use a predetermined electric circuit board corresponding to each model of the small disk.

That is, in the conventional mounting adapter of the disk device, it is necessary to design and manufacture a dedicated electric circuit board for each model of the above-mentioned small disk, so that there is no choice but to carry out so-called multi-product small-quantity production. , Manufacturing was complicated. In addition, even a user who uses this disk device mounting adapter needs to prepare a disk device mounting adapter having an electric circuit board different for each model of the disk device. Since it cannot be diverted to a disk device, it is complicated in purchasing and using.

Therefore, the present invention is proposed in view of the above circumstances, and an object thereof is to provide a disk device mounting adapter that can be used for a plurality of types of disk devices. And

[0013]

In order to solve the above problems and achieve the above object, a mounting adapter for a disk device according to the present invention includes a pair of frames mounted on both sides of the disk device and the disk device. An electric circuit board which is inserted between the mounted frames and supported by the frames and at least a connector socket connected to the disk device is mounted, and both ends of the electric circuit board supported by the frames.
