As described above, when the disc number to be reproduced is pressed out of the disc designation buttons 31 in FIG. 4, or after the EJECT button 32 is pushed to eject the disc M, it is desired to eject the disc designation buttons 31. When the disc number is pressed (step a1), the microcomputer 30 determines whether or not the mini-disc M exists in the accessor mechanism 15 according to the state of the detecting means 1 (step a1).
2) and whether or not the mini-disc M exists in the holder mechanism 19 by an existing detecting means (not shown) (step a)
3) is determined.

Here, for example, reproduction or ejection of the mini-disc M stored in the storage unit 181 is specified, and no mini-disc M is present in the accessor mechanism 15 and the holder mechanism 19 is performing reproduction or after reproduction is completed. If the mini disk M does not exist, the process goes from step a2, a3 to step a4, and the microcomputer 30 drives the accessor mechanism 15 and the elevator mechanism 16 to move the accessor mechanism 15 to a position facing the storage section 181. Then, the rotation roller 25 is rotated to draw the mini-disc M in the storage section 181 into the accessor mechanism 15. Further, as information for specifying the mini disk M pulled into the accessor mechanism 15 in step a5, the disk number “1” corresponding to the storage section 181 of the mini disk M is written in the storage means 2.

When the reproduction is designated, the process proceeds from step a6 to step a7, in which the accessor mechanism 15 is lowered to a position opposed to the holder mechanism 19, and the transport roller 25 is rotated to place the miniature in the holder mechanism 19. The disc M is inserted, the holder mechanism 19 is moved to the chucking position for the chucking mechanism of the reproducing section 20, the reproduction of the mini-disc M is started, and the disc number "1" written in the storage means 2 is changed. Erase (steps a9 and a10).

When the discharge is designated, the process proceeds from step a6 to step a8, in which the elevator mechanism 16 is driven to move the accessor mechanism 15 to a position facing the entire opening 17, and thereafter the shutter mechanism 14 is operated. By opening and rotating the transport roller 25 again, the mini disk M
Is discharged through the front opening 17. Thereafter, the operator manually removes the mini-disc M located in the front opening 17, and when the mini-disc M no longer exists in the accessor mechanism 15, the disc number written in the storage means 2 is erased (step a9). , A10).

On the other hand, reproduction or ejection of the mini-disc M stored in the storage unit is designated, the mini-disc M does not exist in the accessor mechanism 15, and another reproduction is performed in the holder mechanism 19 or another reproduction after the reproduction is completed. Minidisc M (for example,
If there is a disc stored in the storage unit 182), the process proceeds from steps a2 and a3 to step a11, and the microcomputer 30 first performs processing for storing the mini-disc M located in the holder mechanism 19 in the original storage unit. Do.

In this operation, after stopping the reproduction, the holder mechanism 19 is raised obliquely upward to release the chucking state, and the transport roller 25 is rotated in the reverse direction to accessor mechanism 15.
The mini disk M is pulled into the accessor mechanism 15 (step a11).
As information for specifying the storage unit 1 of the mini disc M
The disk number "2" corresponding to 82 is written in the storage means 2 (step a12). Then, the process proceeds from step a13 to step a14, where the elevator mechanism 16 is driven,
The accessor mechanism 15 is moved upward to return the mini disc M to the original storage section 182, and erase the disc number "2" written in the storage means 2 (step a1).
5, a16).

Thereafter, the microcomputer 30 performs processing for reproducing or ejecting the mini-disc M stored in the predetermined storage section designated in step a1, and this operation is performed in steps a4 to a4 as described above.
This is performed according to the operation of step a10. Further, when no mini-disc M is present in the accessor mechanism 15 and ejection of the mini-disc M existing in the holder mechanism 19 is designated, the microcomputer 30 ejects the mini-disc M located in the holder mechanism 19. Perform processing.
This operation is performed from step a3 to steps a11 and a1.
The process proceeds to Step a8 via Steps 2 and 13 and then operates as in Steps a9 and a10. The operation in each step is the same as described above.

As described above, the mini disk M
Does not exist, the operation is the same as the conventional operation except that the disk number corresponding to the storage portion is written to or deleted from the storage means 2 according to the presence or absence of the mini disk M in the accessor mechanism 15. I do. Next, some troubles such as abnormality of various detection switches or power supply abnormality occur, and the apparatus stops in a state where the mini disk M is present on the accessor mechanism 15. Mini disk M on 15
Is determined, the microcomputer 30 first performs a process of removing the mini-disc M existing on the accessor mechanism 15.

In this operation, the mini disk M existing on the accessor mechanism 15 is stored in any of the storage sections 181 to 184, that is, the mini disk M instructed to be reproduced or ejected and the mini disk M on the accessor mechanism 15. This is performed depending on whether the existing mini-disc M matches. When the operation instructed in step a1 is to reproduce data from the mini-disc M existing on the accessor mechanism 15, steps a2 through a17 and a6 are executed.
Then, the operation proceeds to steps a9 and a10 as described above. Also, the operation instructed in step a1 is
In the case of ejection to the mini-disc M existing on the accessor mechanism 15, steps a2 to a17, a
Then, the process proceeds to Step a8 via Step 6, and operates according to Steps a9 and a10 as described above.

On the other hand, the operation specified in step a1 is
In the case of reproduction on a disk M different from the mini-disc M existing on the accessor mechanism 15, the microcomputer 30 first performs processing for removing the mini-disc M existing on the accessor mechanism 15. If the operation instructed in step a1 is to play or eject the mini-disc M that does not exist on the accessor mechanism 15, step a
From step 2 to step a14 via step a17,
First, the elevator mechanism 16 is driven, the accessor mechanism 15 is moved upward to return the mini disk M to the original storage section, and the disk number written in the storage means 2 is deleted (steps a15 and a16). Thereafter, the microcomputer 30 performs processing for reproducing or ejecting the mini-disc M stored in the predetermined storage unit designated in step a1, and this operation is also performed in steps a4 to a10 as described above. It is performed according to the operation.

It should be noted that the mini disk M is placed on the accessor mechanism 15.
When the apparatus stops in the state where the mini disc M exists, there is a possibility that the mini disc M itself has an abnormality. In such a case,
If the mini-disc M is forcibly ejected, the subsequent control can be performed more reliably. Therefore, as another embodiment, FIG.
When it is determined in step a2 of the flowchart of FIG.
Similarly to the operation in step a8, first, the elevator mechanism 16 is driven to move the accessor mechanism 15 to a position facing the entire opening 17, the shutter mechanism 14 is opened, and the transport roller 25 is rotated again, so that the mini disk M
Is discharged through the front opening 17. Thereafter, as in steps a9 and a10, the operator removes the mini-disc M located in the front opening 17 by hand, and when the mini-disc M no longer exists in the accessor mechanism 15, the disc written in the storage means 2 is removed. Clear the number.

When the mini disk M located in the front opening 17 is removed, the microcomputer 30
Performs a process for reproducing or ejecting the mini-disc M stored in the predetermined storage unit designated in step a1, and this operation is performed in accordance with the operations in steps a4 to a10 as described above. As described above, when the apparatus stops in a state where the mini-disc M is present on the accessor mechanism 15, the subsequent control can be reliably performed by forcibly ejecting the mini-disc M.

In the above embodiment, the detection of whether or not the mini-disc M exists in the accessor mechanism 15 is performed by the detecting means 1 provided in the accessor mechanism 15, but as another embodiment, The same detecting means is used for each storage unit 1
A comparison between the number of mini-discs M stored in the device and provided in the holder mechanism 19 and the number of mini-discs M present in each of the storage portions 181 to 184 and the holder mechanism 19 is provided. Accordingly, it may be indirectly detected whether or not the mini-disc M exists in the accessor mechanism 15.

[0032]

As described above, according to the present invention, when the detection means detects that the recording medium is present in the accessor section, the recording medium present in the accessor section is read by a magazine, an opening or a reproduction section. Since the operation of transferring the data to any one of the units is performed with priority, it is possible to prevent an abnormal disk from being left in the apparatus and prevent other operations from being hindered.

Further, it is possible to prevent the erroneous determination that the designated recording medium does not exist in the apparatus due to the presence of the recording medium in the accessor unit, and to specify the designated recording medium. The operation as performed can be performed. Further, even when another recording medium is present in the accessor unit, the specified operation can be performed on the specified recording medium.
