In recent years, a plurality of CDs have been stored and selectively played. A CD player with a disc exchange function capable of performing the following has been developed.

For example, in a CD player proposed in Japanese Patent Publication No. 4-19626, a desired plurality of CDs are selected from a plurality of CDs housed in the apparatus main body.
In order to select a desired song in each selected CD and automatically play the selected song, a desired CD number and a song number in each CD are all registered in a memory in advance by a key input operation. At the time of automatic performance, a CD performance operation is executed based on the data in the memory.

A CD player proposed in Japanese Patent Application Laid-Open No. H4-245085 is intended for a plurality of magazines each accommodating a plurality of CDs, and one of the magazines is exchangeably set in an apparatus main body. Is what is done. In the CD player, names are assigned to a plurality of magazines prepared in advance, these magazine names are registered in a memory, and a plurality of Cs contained in each magazine are stored.
D is also assigned a name for each magazine, and these C
The D name is also registered in the memory. Therefore, data on a lost or damaged disk after registration can be erased from the memory without setting the disk in the apparatus main body.

[0005]

However, in a conventional CD player with a disk exchange function, each of a plurality of CDs is provided with a CD name that can be distinguished from other CDs, and a desired CD name is provided for automatic performance. A plurality of CD names must be specified, and the operation is extremely complicated. In particular, in a CD player for a large number of CDs, music recorded on a CD spans a plurality of genres such as classical, jazz, and rock. There is a demand to select and play automatically. In this case, the conventional C
In the D player, all the names of a plurality of CDs included in a desired genre must be input and registered, and the operation becomes complicated.

An object of the present invention is to specify a name of each disk when automatically performing a plurality of disks included in a specific category arbitrarily set by a user among a plurality of disks to be played. An object of the present invention is to provide a disc player in which an automatic performance is executed simply by designating a desired category.

[0007]

According to the present invention, there is provided a disk player having a disk exchange function, comprising: a memory for storing a category name for each disk storage unit; The memory means is searched based on the category designation means to be operated and the category name designated by the operation of the category designation means, and the plurality of disks in the plurality of disk storages to which the category names are assigned are automatically and continuously searched. Automatic reproduction means for reproducing, a category input means to be operated when registering a new category name in the memory means, and category registration for registering a category name in the memory means in accordance with an operation of the category input means Means.

More specifically, the apparatus further comprises a display and category display means for displaying a category name for each disk storage section on the display. Here, the category display means, when designating a category name by operating the category designation means to execute automatic reproduction, stores all of the disc storage units in which the playable discs are stored in the memory means. The category names are sequentially displayed on the display.

[0009]

In the disc player according to the present invention, when discs are stored in the plurality of disc storage sections, respectively, the category input means is manually operated to input a category name for each disc storage section. In response, the category registration unit registers the category name in the memory unit for each disk storage unit. Here, the category name is not limited to a genre name of music such as classical music, jazz, rock, etc., and can be set arbitrarily as long as it represents a category of content recorded on the disc.

Thereafter, when performing automatic reproduction of the disc, the category designation means is operated to designate the category name of the disc to be reproduced. In response, the automatic playback unit searches the memory unit based on the designated category name, and recognizes a plurality of disk storage units to which the category name has been assigned. Then, a control signal for automatically reproducing a plurality of disks in these disk storage units in a predetermined order is created and sent to a control circuit of the disk player. As a result, a plurality of discs included in the designated category are sequentially reproduced. Here, as a reproduction order of these disks, various methods that can be set in advance, such as a method in which the disk storage units are arranged or a method of playing in a random order, can be adopted.
