[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting adapter for a disk device which holds an outer casing of the 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 information signals on a disk serving as a recording medium for information signals, such as a magnetic disk, an optical disk or a magneto-optical disk.

[0003] This disk device comprises a rotary drive mechanism for rotating the disk, and a magnetic or optical type for writing and / or reading information signals to and from the disk rotated by the rotary drive mechanism. Head devices and the like, and these are housed in an outer housing.

By the way, the above-mentioned discs 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 has been proposed. In the disk device, the size of the outer casing is determined according to the diameter of a disk used as a recording medium.

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

That is, the small disk and the large disk device have different sizes of the outer housing, and also have different positions and structures of electrical connectors and the like provided on the rear surface and the like of the outer housing. Therefore, it is not compatible with various external devices such as a so-called computer device or word processor device to which these disk devices are attached or connected. The mounting adapter for the disk device attaches the small disk to the outer casing of the small disk to provide compatibility with the large disk device for the small disk.

The mounting adapter of the disk device has a pair of frames mounted on both sides of an outer casing of the small disk. These frames are attached to both sides of the outer casing of the small-sized disk so that the distance between the outer side faces of each other is equal to the distance between the outer side faces of the outer casing of the large-sized disk device. It has been done. The size of these frames in the height direction is 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.

A plurality of models are used in which the positions, shapes, and the like of the connector portions are different from each other. Therefore, in the mounting adapter of the disk device as described above, it is necessary to use a predetermined electric circuit board corresponding to each model of the small disk.

That is, in a conventional mounting adapter for a disk drive, it is necessary to design and manufacture a dedicated electric circuit board for each type of the above-mentioned small disk, so that a so-called high-mix low-volume production has to be performed. , The production was complicated. In addition, even a user who uses the mounting adapter of the disk device needs to prepare a mounting adapter for the disk device having a different electric circuit board for each type of the disk device. Cannot be diverted to a disk drive, which makes the purchase and use complicated.
