2. Description of the Related Art Generally, in a disc reproducing apparatus, information signals such as Japanese dictionary information and English-Japanese dictionary information are recorded on an information disc such as an optical disc, and desired information is read from the information disc and read out. It is known that information is displayed on the display unit.

This is a disc drive device for rotating and operating an information disc such as an optical disc on which predetermined information is recorded, and a disc drive device for reading and reproducing the information recorded on this disc, and for reading and reproducing from the information recorded on the information disc. It is composed of a keyboard device for selecting desired information to be reproduced and a display device for displaying the information read from the information disc as character information.

In this type of disk reproducing apparatus, a disk drive apparatus, a keyboard apparatus, and a display apparatus are independent apparatuses, and these apparatus can be combined and installed on a desk or the like for use. Since each of the devices that make up is large, it is impossible to carry and use.

On the other hand, in the case of information discs such as optical discs, since the recording density has been remarkably improved, one Japanese dictionary or one booklet is provided on one optical disc having a diameter of 8 cm. Information corresponding to the English-Japanese dictionary can be recorded.

Therefore, a small optical disk capable of high-density recording is carried, and desired information is easily read from the optical disk at a free place and reproduced, and the reproduced desired information is displayed on a display device as visible information. It is desired to provide a device capable of displaying.

In order to meet such a demand in recent years, a disk drive device, a keyboard device and a display device, each of which is independently configured, are integrated to achieve miniaturization of the entire device. Furthermore, a compact disc player that is portable enough has been proposed.
The present applicant has previously disclosed it as a "portable disc player" in Japanese Patent Application No. 11619 of 1990.
