TECHNICAL FIELD The present invention relates to a replacement adapter for a recording / reproducing apparatus, and more particularly to a recording / reproducing apparatus using a recording medium smaller than a recording medium originally usable in electronic information devices and the like. The present invention relates to a replacement adapter for a recording / reproducing apparatus which can be incorporated without changing its structure.

2. Description of the Related Art In general, electronic information devices such as personal computers and word processors are equipped with a magnetic disk device (recording / reproducing device) as an external storage device. The information processed by the control circuit in the device is recorded on the magnetic disk, or the recorded information is sent to the control circuit according to a command from the control circuit to be reproduced.

There are several types of magnetic disks with different outer diameters,
For example, there are those called 3.5 inches, 5.25 inches, 8 inches, etc. Therefore, as the magnetic disk device, a device for each size is prepared corresponding to each size of the magnetic disk. Generally, one type of magnetic disk device is attached to one set of electronic information devices, and normally, the size of a magnetic disk that can be used by one device is one type.

However, as the high density recording in the magnetic disk device has progressed and the performance of the magnetic disk device has improved, a 3.5-inch magnetic disk having a relatively small diameter has been widely used. Therefore, there is an increasing need for exchanging information between a 3.5-inch magnetic disk and a conventional 5.25-inch electronic disk, but in such a case, a magnetic disk device must be added separately. The magnetic disk device has a problem that not only an extra installation space is required, but also its operation is complicated.

Therefore, the applicant of the present invention, in order to solve the above problems,
In No. 102071, for example, it is proposed that a 3.5-inch magnetic disk device is incorporated in a frame formed to have the same size as a 5.25-inch magnetic disk device, and that the magnetic disk device can be mounted in an electronic information device. ing.

However, since the previously proposed magnetic disk drive can be installed with different size magnetic disk drives, information exchange between different size magnetic disks, transfer of contents, etc. can be performed by a normal method. However, there are the following problems. That is,
In the above device, for example, before assembling the 3.5-inch magnetic disk device to the same frame as the 5.25-inch magnetic disk device, the 3.5-inch front bezel must be removed, and then the 5.25-inch magnetic disk device. A 3.5-inch magnetic disk drive must be attached to the front bezel that has the same size and is formed with an insertion slot into which 3.5-inch can be inserted. Therefore, in the above proposed device, when replacing the magnetic disk device with a different size,
The manufacturing man-hours required for the replacement are the same as those of a single device or more, and it is difficult for the user who operates the electronic information device to easily replace it. Therefore, even a person with little experience can easily change the size of the magnetic disk device. It is demanded that it can be replaced with another one.

Then, this invention aims at providing the exchange adapter of the recording / reproducing apparatus according to the said request | requirement.
