By operating (e.g., pressing) the frequency-specific eject key, the controller according to the frequency-specific ejection device
The reproduction frequency of the loaded disk is measured, the disk with the lowest reproduction frequency is determined, and the disk is ejected. This apparatus is provided with a storage means for storing the number of times the loaded disc has been reproduced since the operation of the frequency-specific eject key. Then, by operating the frequency-specific eject key and ejecting the disc with the lowest reproduction frequency, the storage is cleared,
Start a new memory.

The ejection device according to frequency as described above is
For example, as shown in FIG. 20, a controller including the above-described functions is provided in a circuit including a disk reproducing device and the like.
0 and a frequency-specific eject key 701. The ejection device according to frequency configured as described above operates as follows. In other words, as shown in FIG. 21, the controller 700 determines by itself whether or not the frequency has been measured (counted up) for each of the loaded discs. Perform this measurement. Further, the controller 700 monitors whether or not the frequency-specific eject key 701 has been operated. When the frequency-specific eject key 701 has been operated, the controller 700 determines the disc with the lowest reproduction frequency and Eject the disc. It is also conceivable that two or more reproduction frequencies are the same. In such a case, any of the discs may be ejected, or an arbitrary number of these discs may be ejected.

The ejection device according to frequency as described above is
Although it did not exist conventionally, for example, with the configuration as shown in FIG. 20 above, this frequency-specific ejecting device was provided, and if it was attached to the above-described in-vehicle disk autochanger according to the present invention, a disk with a low frequency of reproduction was loaded. It is possible to prevent the disk from being left as it is, and in combination with the above-described effects of the present invention, it is possible to substantially increase the number of loaded disks.

In the above-mentioned frequency-ejecting apparatus, it is described that the disc with the lowest reproduction frequency is ejected. However, instead of this, the controller 700 counts the reproduction frequency of each disc, and It is also possible to calculate the number of reproductions of each disk with respect to the number of reproductions, and eject the disk whose calculated value is less than a predetermined value (for example, 10%). Since a microcomputer (CPU, MPU) can be used as the controller 700, the above-described calculation processing can be easily performed by incorporating the program.
