1 illustrates a preferred embodiment of a drive status display device of a CD-ROM player according to the present invention with reference to the accompanying drawings.

FIG. 1 is a schematic block diagram of a drive status display device of a CD-ROM player according to the present invention. The microcomputer 1 has 8 bits of data and a display controller 2 according to a control signal applied from the outside. The latch signal which controls the operation | movement of the latch 3 inside is output.

The display control unit 2 receives data and a control signal from the microcomputer 1 to control the display element 4. At this time, the display control unit 2 simultaneously receives the 8-bit data and the latch signal applied from the microcomputer 1 and latches the latch signal for a predetermined time and outputs the latch signal to the data decoder 5.

The data decoder 5 decodes 8 bits of data applied from the latch 3 into a control signal of a predetermined type and outputs it to the display element 4.

The display element 4 displays a letter indicating whether or not the letter of the CD-ROM drive and the disc are mounted in accordance with a control signal applied from the data decoder 5.

The operation of the drive status display apparatus of the CD-ROM player having the above configuration is as follows.

When a number of CD-ROM drives are attached to a number of connectors mounted on an initial CD-ROM player, each CD-ROM drive is assigned a unique letter and the main power is turned on. For each CD-ROM drive, it sequentially scans the disc for burning and the specified letter, and outputs 8-bit data of whether the disc is loaded and the specified letter. In addition, the microcomputer 1 outputs a latch signal for controlling the operation of the latch 3 configured in the display control unit 2.

That is, assuming that a CD-ROM drive is mounted with three CD-ROM drives initially, the first letter of the CD-ROM drive is 'F' and the second letter of the CD-ROM drive is designated. Is 'S', and the third CD-ROM drive designation letter is 'V', the microcomputer 1 searches for information on whether or not a disc is loaded and the letter from each CD-ROM drive. Outputs 8-bit data indicating whether the disk is mounted and 'F' to the latch 3 connected to the first CD-ROM drive, and whether or not the disk is mounted to the latch 3 connected to the second CD-ROM drive. 8 bits of data representing S 'are outputted, and 8 bits of data representing' V 'are output to the latch 3 connected to the third CD-ROM drive.

The 8-bit data output from the microcomputer 1 is applied to the latch 3 in the display control unit 2, and the latch 3 is the 8-bit data applied according to the latch signal applied from the microcomputer 1. Latch for a predetermined time.

After a predetermined time has elapsed, 8-bit data is applied to the data decoder 5, converted into information about a character representing the unique letter of the first CD-ROM drive, and then output to the display element 4. The display element 4 uses the character information applied from the data decoder 5 to display the letter of the CD-ROM drive in the state as shown in FIG. 2A and 2B.

At this time, when the disc is mounted in the CD-ROM drive by controlling the output information of the data decoder 5 according to the initially designated state, the character portion is displayed in bright colors as shown in FIG. Is displayed in a dark color, and when a disc is not loaded in the CD-ROM drive, the character portion as shown in (b) of FIG. 2 is displayed in dark color, and the background portion is displayed in light color.

In addition, when a disc is loaded in the CD-ROM drive so as to be contrary to the foregoing, according to the user's selection, the character part is displayed in dark color and the background part is displayed in light color, as shown in FIG. When a disc is not loaded in the CD-ROM drive, as shown in FIG. 2A, the letter portion may be displayed in light color and the background portion may be displayed in dark color.

In the above cases, the operation flow of the microcomputer 1 will be described with reference to FIG. 3. Here, the operation flowchart shown in FIG. 3 shows a search operation for each drive. The microcomputer 1 sequentially determines whether a disk is mounted and displays a drive designation letter for each drive according to the operation flowchart shown in FIG.

Assuming that the designated letter of the drive is 'F', in the search operation for the first drive, the microcomputer 1 checks whether or not a disc is loaded in the drive (SI), and determines whether there is a disc (S2). If it is determined in step S2 that the disc is loaded, the microcomputer 1 determines that the designated letter of the drive is 'F' (S3), and then the drive designated letter 'F' and the disc in the latch 3 are identified. Outputs 8 bits of data indicating that is installed (S4).

If it is determined through the above step 32 that the disk is not mounted, the microcomputer 1 determines that the designated letter of the drive is 'F' (S5), and the latch designated by the drive designated letter 'F' in the latch (3). 8 bits of data indicating that the disc is not loaded are output (S6).

The microcomputer 1 outputs a latch signal to the latch 3 (S7) to control the operation of the latch 3.
