[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an autochanger player for compact discs (hereinafter referred to as CD), and in particular to an autochanger player for compact discs (hereinafter referred to as CD), and in particular for a compact disc (CD) autochanger player. The present invention relates to a device for displaying the contents of a CD.

[Prior Art] Conventionally, a so-called CD automatic chain player has been developed, in which a plurality of CDs are stored in a magazine, the magazine is attached to the main body of the player, and desired CDs and desired songs can be selected and played continuously. have been considered and commercialized. This kind of CD auto-change r-player has multiple C
This is very convenient for continuous playback of CDs and continuous playback of arbitrary songs selected across a plurality of CDs.

[Problems to be Solved by the Invention] In such a conventional CD autochanger player, when a CD is stored in the -H magazine, the title recorded on the CD cannot be recognized. Especially when you have multiple magazines, it becomes difficult to find the desired song, and you have to either remove the CD from the magazine and check it, or make a list of the titles of the CDs stored in the magazine. Ta.

[Means for Solving the Problems] The present invention includes a magazine storing a plurality of CDs and a memory means, and stores information recorded on the CD in the main body and necessary information from a data input means in the memory means. Seshime,
This is a CD autochanger player equipped with means for displaying this.

It is also a CD autochanger player that has a magazine equipped with a display device and an internal power source for driving.

Furthermore, the CD player is equipped with a means for driving the display device with the power supply of the main body when attached, and a charging means.

[Example] The present invention will be described below with reference to an example shown in FIG. In FIG. 1, 1a and 1b are magazines, respectively, and 2 is a CD autochanger player body. Each of the magazines 1a and 1b includes a CD storage section 11 for storing a plurality of CDs, and a non-volatile memory (22FROM>1
2. In order to record information from the main body into the non-volatile memory 12, a connector 13 is provided which connects to the connector 23 on the main body side when the magazine 1a is attached to the main body 2.

On the other hand, the main body 2 includes an optical pickup 21 that detects information recorded on the CD 3 pulled out from the magazine, a signal processing means 22 that processes the signals detected by the pickup 21 in a predetermined order, and a display means 24. Data input means 25 such as a keyboard, memory means 26, backup power supply 27 for the memory means, and signal processing means 2
2. CPU 28 that controls display means 24, memory means 26 and data input means 25, and magazine connector 1
3 is provided.

To explain the pulling operation in the above configuration, 1>Magazine 1
a to the main body 2, and input the desired C from the data input means 25.
When D is selected, the desired CD 3 is pulled out from the magazine 1a and picked up by the pickup 21 as a TOC (Table O
f contents (total number of songs, total play time, etc.) are read out, and TOC information specific to each CD is stored in the memory means 26.

2) For the TOC information stored in the memory means 26, the memory area code is sent to the non-volatile memory 12 of the magazine 1a, and the CD 3 currently being pulled into the main body 2 side is sent.
to be memorized in response to.

3) The data input means 25 inputs information necessary for displaying the track list of the CD 3, and stores the input information in the nonvolatile memory 12 in correspondence with the memory area code.

4) Perform the write operation on all CDs in the magazine 1a and store all necessary information in the nonvolatile memory 12.

Through the above operations, the nonvolatile memory 12 in the magazine 1a retains the necessary information to be displayed on the display means 24, such as the first TOC song of the stored CD.

When the above operations are completed, the magazine 1a is removed from the main body, but the information stored in the nonvolatile memory 12 is retained.

5) Perform the above operation with the magazine 1b or another magazine mounted, and store the necessary information of the CDs stored in each magazine in the nonvolatile memory of each magazine.

After performing the above operations and installing each magazine into the main body 2,
The information held in the non-volatile memory 12 is
3.23 to the main body side, and the display means 2 of the main body
By displaying the information in 4, the contents of the CDs stored in each magazine can be confirmed.

FIG. 2 shows another embodiment, and the same numbers are the same as in FIG. 1. In the figure, the magazine 11a includes a CD storage section 11,
In addition to the non-volatile memory 12 and the connector 13, it is provided with a display means 14, an internal power supply 15 for driving the display means, and a connector 19 for supplying the driving power from the main body. Further, a connector 29 is added to the main body 2 to be connected to the connector 19 in order to supply the power of the main body 2 to the magazine 11a as a power source for driving the display means 14 of the magazine 11a.

In the above configuration, if the information necessary for display is stored in the non-volatile memory of the magazine 11a by the operations 1) to 5) above, when the magazine 11a is pulled out from the main body 2, the internal drive power can be used! The display means 14 on the side of the magazine 11a driven by the display means 15 can display the necessary time at all times or by adding an appropriate switching means.
You can easily check the stored CDs. Also, main body 2
When installed in the main body 2, the display means 14 is driven by the power supply on the main body 2 side, and when installed on the main body 2, the display means 14 is driven by the power supply on the main body 2 side, and the internal N source 15 for driving is charged. You can also force it. Also, magazine 1
Of course, the necessary information stored in 1a can also be displayed on display means 24 of main body 2.

[Effects of the Invention] According to the present invention as described above, it is possible to display a display that identifies a plurality of CDs stored in a magazine, making it extremely easy to select a desired CD and a desired song in the magazine. Become.

Further, since the information stored in the memory means is retained even when the magazine is removed from the main body, the information can be used repeatedly. Further, in the second embodiment, since the magazine is provided with a display means and an internal drive power source, it is possible to identify the CDs in the magazine even when the magazine is pulled out. In addition, by driving the display means in the magazine with the main body's power supply when installed, wear and tear on the internal power supply can be suppressed, and by providing a charging means, the internal power supply can be replaced at longer intervals or can be used semi-permanently. be. still,
Although the case where non-volatile memory is used as the memory means has been described, it is also possible to use other types of memory by providing a backup power source within the magazine.
