Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] In a disc reproducing apparatus having a mechanism for selecting one disc from a magazine accommodating a plurality of discs and setting it in the player section, the designated disc is completely taken out within a certain time. If not, remove the other disk instead to avoid system down.

[Industrial application field]

The present invention is a magazine containing a plurality of discs
The present invention relates to a disc reproducing apparatus for selecting a single disc and setting it in a player section.

[Conventional technology]

In a disc reproducing apparatus with an autochanger, which stores a plurality of discs to be reproduced by the player unit in a magazine in advance, and automatically selects one of the discs to set in the player unit, a disc selection mechanism and a loading / unloading mechanism driven by a motor. Is equipped with. When the desired disc number is input from the operation unit, the control unit drives the disc selection mechanism motor to take out the disc from the magazine, and then drives the disc insertion / ejection mechanism motor to drive the disc unit. Set to.

[Problems to be solved by the invention]

In the above-mentioned disc reproducing apparatus, if the disc cannot be taken out due to a catch or the like when the disc is selected (taken out), if a current flows through the motor or its driver IC for a long time, it causes thermal destruction. In order to prevent this, there is a method of shutting down the system when the disc ejection is not completed within a certain time.

However, once the system goes down, it is inconvenient because the disc number has to be set again in order to bring it into the reproducing state. Therefore, in the present invention, a system is proposed in which another disc is taken out and reproduced instead of the system so that the system does not go down as much as possible.

[Means for solving problems]

The present invention relates to a disc reproducing apparatus provided with a mechanism (5) (6) for selecting one of a plurality of discs (7) housed in a magazine (1) and setting it in a player section (2). If the removal of the disc specified by the section (3) is not completed within a certain time, the process proceeds to the next removal of the disc, and when the removal is completed, the reproduction is started, and if the removal fails for a certain number of times, the system is down. It is characterized by comprising a control unit (4).

[Action]

Even if the specified disc fails to be ejected, the system will not be brought down immediately, but if another disc can be ejected and set in the player section instead, the playback state can be maintained even though the disc is not the desired disc, and the system will go down. It is possible to avoid the reset operation that accompanies it. Since the above-mentioned automatic disk changer called an autochanger is intended to be used in a vehicle, it is desirable to operate with as few operations as possible.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of the present invention. (1) is a magazine, (2) is a player section, (3) is an operation section, and (4).
Is a control unit, (5) is a disk selection mechanism, and (6) is a disk insertion / ejection mechanism. Disk selection mechanism (5) consists of a motor (51) and a rack and pinion pair (52), the magazine (1) in the disc _{(71), (7 2),} take out one ....... The disk insertion / ejection mechanism (6) is a motor (6
1) and a rack and pinion pair (62), the disc taken out from the magazine (1) is loaded into the player section (2).
The disc (7) in the player section (2).
₀ ) is returned to the magazine (1). (21) of the player section (2) is a read head. The disc (7) is, for example, a CD (compact disc).

In the magazine (1), for example, disk numbers NO.1 to NO.
Ten discs (7) of 10 are housed. The desired disk number is designated by inputting (1) or a plurality of sets from the operation unit (3). The control unit (4) sends a disc selection control signal to the motor (51) of the disc selection mechanism (5) so that the inputted disc number is selected, and the ejected disc is set in the player unit (2). As described above, the disc insertion / ejection control signal is sent to the motor (61) of the disc insertion / ejection mechanism (6). At this time, the timer (41) is started to activate the disc selection mechanism (5).
The success or failure of ejecting the disc is monitored. If this disc removal is not completed within a certain time, an alarm is issued and the next disc is selected. The next disc is (1) When the designated disc number is one set, the number next to the designated number (for example, when NO.5 is designated, NO.6 and NO.10 are designated. When it is being played, it is the No. 1) disc,
(2) When there are a plurality of sets of designated disc numbers, the disc has the next designated number. The counter (42) counts the number of fetch trial lines. In the case of (1), the system down signal is issued when the number of sheets reaches 10, and in the case of (2), the system down signal is issued when the number of designated sheets is reached. FIG. 2 is a flow chart showing the above-mentioned processing by the control unit 4.

[Effect of device]

As described above, according to the present invention, it is possible to avoid the system down caused by the disc removal failure with the autochanger as much as possible, and it is possible to continue the operation with a small number of operations.
