BRIEF SUMMARY
This application is a 371 of PCT/JP94/00637, filed Apr. 18, 1994.
FIELD OF THE INVENTION
The present invention relates to a disc reproducing apparatus for a CD-ROM drive or the like and an electronic apparatus.
DESCRIPTION OF THE PRIOR ART
In recent years, the size and weight of disc drives that use optical discs as recording mediums have been reduced. Thus, built-in type disc reproducing apparatuses that are accommodated in computers have been actively developed. In some disc reproducing apparatuses, a disc drive system, an optical pickup, and so forth are disposed in a disc mounting table that holds a disc. This table can be loaded into and unloaded from the cabinet of the disc reproducing apparatus.
In such disc reproducing apparatuses, a printed circuit board disposed in the cabinet is connected to a printed circuit board disposed in the table through a flexible cable. FIG. 24 shows a connection of the flexible cable. In the drawing, reference numeral 101 is the flexible cable. Reference numeral 102 is the cabinet. Reference numeral 103 is the printed circuit board. Reference numeral 104 is the table. The flexible cable 101 is flatly connected between the printed circuit board 103 disposed on the cabinet 102 and the printed circuit board (not shown) disposed on the table 104.
Thus, when the table 104 is loaded into the cabinet 102, as shown in FIG. 24, the center portion of the flexible cable 101 swells upwardly. Consequently, the surfaces of the flexible cable 101 contact the cabinet 102 and other parts of the apparatus and thereby the flexible cable 101 will be damaged. To prevent the flexible cable 101 from being damaged, the space for the flexible cable 101 should be provided in the direction of the thickness of the cabinet 102. However, if such a space were provided, the thickness of the apparatus would increase.
In some recent disc reproducing apparatuses, to reduce the thickness, a clamper that secures an optical disc to a turn table is omitted.
However, in such disc reproducing apparatuses, the disc may drop or become dislodged from the turn table. In addition, in such apparatuses, if the disc is inclined on the turn table, when the table is loaded into the cabinet, the surfaces of the disc will frictionally contact adjacent parts of the apparatus and thereby the disc will be damaged.
On the other hand, in such disc reproducing apparatuses, the table loaded into the cabinet should be secured at a predetermined position of the cabinet so as to stably reproduce data from the disc. Various mechanisms that secure the table loaded into the cabinet have been proposed. However, lock mechanisms that are small in size, have good operability, and are trouble-free are difficult to accomplish. For example, if the size of the lock mechanism is reduced, when the table is unlocked, the drawing amount of the table becomes insufficient. Thus, operations for mounting the disc on the table and for unloading the disc from the table become troublesome.
The present invention is made to solve the above-mentioned problems.
An object of the present invention is to provide an electronic apparatus that allows the space for a flexible cable to be remarkably reduced.
Another object of the present invention is to provide an electronic apparatus that allows the durability of a flexible cable against the twisting and bending to be improved.
Yet another object of the present invention is to provide an electronic apparatus with a simple structure that allows a second cabinet to be unloaded largely from a first cabinet.
Still another object of the present invention is to provide a disc reproducing apparatus that allows a disc to be secured at a position where data is reproduced without need to use a disc clamper.
Still another of the present invention is to provide an electronic apparatus that shares a grounding member with another function so as to allow the number of parts of the apparatus to be reduced.
SUMMARY OF THE INVENTION
In an electronic apparatus of the present invention, a flexible cable disposed in a first
