[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an audio device for playing a disc of an autochanger, and more particularly to an audio device suitable for memory play of playing a disc.

[0002]

[Prior art]

 Conventionally, a memory-playable audio device for disc playback can be used to select the disc number and track number of the desired song (track) from the multiple discs stored in the magazine during the memory set mode. The operation key of the head unit was operated to select it, and the selected disk data was stored in the memory built into the first system microcomputer of the autochanger.

The first system microcomputer controls the disk reproducing device by the previously stored memory data, and executes the memory play for performing the disk reproducing operation of the memory data.

The above-mentioned audio signal of the disc change auto changer is supplied to the head unit, the reproduced voice signal is amplified by the amplifier built in the head unit and output to the speaker, and the user listens to the disc play music of the memory play. It was

As described above, it was possible to easily perform a memory play of a desired performance song from a plurality of discs stored in the magazine by utilizing the auto changer function.

[0006]

[Problems to be solved by the device]

 However, the above-described audio device for memory-playing disk playback using the conventional autochanger does not store the song itself, but the disc number and track number of the song set. Therefore, if the discs in the magazine are replaced, the stored disc number and track number are selected and played back when the memory play is executed. It had the drawback of being different from the song.

Further, since the disk number and the track number of the above-mentioned disk are recorded in the memory by the 10 keys from 0 to 9, there is a drawback that the working time for storing in the memory becomes extremely long.

The present invention has been made in view of the above points, and an object thereof is to solve the drawbacks of the conventional example, record the unique data of the reproduction disk in the memory, and replace the disk of the magazine with the memory. We provide audio equipment that selects and plays the songs that the operator wants even when playing.

[0009]

[Means for Solving the Problems]

 The audio device of the present invention comprises an autochanger having a disc reproducing device and a first microcomputer, and a head unit having an audio output device and a second system microcomputer to which a display and operation keys are connected. In the audio device, an external storage unit connected to the first system microcomputer and a memory set key in the operation keys are provided, and the unique data of the playback disc is stored in the external storage unit by the memory set key. A memory means and a memory play reproducing means for reproducing and playing a disc that matches the unique data stored by the memory play instruction from the operation key are provided.

[0010]

[Action]

 According to this invention, a memory set key for requesting a memory to store the operator's favorite song is provided in the operation keys of the head unit, so that the song desired to be stored during the disc replay of the autochanger. On the other hand, when the memory set key is pressed, the second system microcomputer incorporated in the head unit requests the first system microcomputer of the autochanger to store the reproduced disc data.

In response to the above request, the first system microcomputer of the autochanger uses the TOC data of the disk being played in the external storage unit (RAM) connected to the first system microcomputer and the track number currently being played. To store unique data.

On the other hand, contents such as TOC data of all the disks in the magazine are stored in the memory in the first system microcomputer.

If the operation keys of the head unit are operated by the audio device thus stored and the memory play start is requested, the first system microcomputer of the autochanger examines the TOC data in order from the disk with the smallest disk number. If there is memory data with the same TOC value, the disc can be loaded, the tracks of the memory data can be played back, and all the discs in the magazine can be played back in sequence.

In this way, since the memory play is performed with the unique data such as the TOC data of the reproduction disc, even if the discs in the magazine are exchanged, if the exchanged disc's peculiar data is stored, there is no doubt in advance. Only the selected favorite song can be played back by the memory play function.

【Example】

 An embodiment of an audio device according to the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a block diagram showing the configuration, and FIGS. 2 and 3 are flowcharts for explaining the operation.

In the figure, reference numeral 1 is an autochanger, and this autochanger 1 is a disc reproducing device 2 for reproducing a disc selected from a plurality of discs stored in a magazine, and an amplifier for amplifying an audio signal from the disc reproducing device 2. It is output through the peripheral circuit 3 composed of a circuit and a mute circuit.

Reference numeral 4 denotes a first system microcomputer with a built-in autochanger 1. This system microcomputer 4 is basically composed of a CPU, a ROM, a RAM, an input boat and an output boat (not shown), as well known. A program for controlling the CPU is written in the CPU, and the CPU executes arithmetic processing while fetching external data required from the input board or exchanging data with the RAM according to this program. Accordingly, the processed data can be output to and stored in the RAM 5 of the external storage unit connected to the output port, and the operation of the disc reproducing apparatus 2 can be controlled.

Reference numeral 6 is a voice signal line, 7 is a communication line connected to the first system microcomputer 4, 8 is a head unit, and this head unit 8 is composed of a source selector 9, an output amplifier 10 and a speaker 11. The second system microcomputer 12 has the audio output device described above and is connected to the display 13 and the operation keys 14.

By providing a memory set key to the operation keys 14 of the head unit 8 and pressing the memory set key, it is possible to request the storage of the disc specific data of the song that the operator likes. This storage operation will be described with reference to the flow chart shown in FIG.

When storing the unique data such as TOC data of the disc being reproduced and played by the disc replay device 2 of the autochanger 1 (step S1), the first system microcomputer 4 of the autochanger 1 uses the memory set key. A memory set request of an instruction command supplied from the second system microcomputer 12 of the head unit 8 by the operation through the communication line 7 is determined (step S2).

In response to this memory set request, the first system microcomputer 4 of the autochanger 1 stores the TOC data of the disk being played by the disk replay device 2 and the track number currently being played in the RAM 5 of the external storage unit ( Step S3). In this way, it is possible to store and process all of the disc data of the music piece of one's liking (step S4).

After the unique data of the disc is recorded in the external RAM 5, the first system microcomputer recognizes the contents of all the discs in the magazine, that is, the unique data of the disc in order to reproduce and play only the recorded music. Need to be This is because the memory play of the present invention does not identify the played music piece by the disc number or track number alone, but by the memory data such as TOC data unique to the disc.

Therefore, if there is an opportunity to play the disc of the favorite song before the memory play is started, the TOC data of the disc is stored in the storage unit inside the first system microcomputer 4 at the time of this playing. deep. In this way, the unique data of the disk can be stored in the external storage unit 5 and the first system microcomputer 4, respectively, and the memory play can be executed. The operation of this memory play will be described with reference to the flowchart of FIG.

When the memory play start is requested by operating the operation keys 14 (step S 10), the first system microcomputer 4 of the autochanger 1 sequentially stores the disks stored in the external storage unit 5 in order from the disk having the smallest disk number. The TOC data stored in the first system microcomputer 4 is checked, and if the memory data of the same TOC value exists in the memory of the first system microcomputer 4 (step S11), the first system microcomputer 4 is rewritten to the disk. The disk stored in the magazine of the sexual device 2 is taken out and loaded, and the track of the memory data is reproduced and played (step S12).

When there is no valid TOC data stored in the first system microcomputer 4 (step S 11), it is determined whether the disc data of all the stored discs is valid or invalid. If it is valid, the unknown disc is loaded by the disc reproducing device 2 if the unknown disc, that is, the disc which has not been played and played even once after inserting the magazine, is read by the disc reproducing device 2 and the TOC is determined. The data is stored in the first system microcomputer 4 (step S14).

If the disk data is invalid (step S13), the display unit 13 indicates that the disk data of all the disks are invalid (step S17).

In this way, the memory-play disc unique data stored in advance in the external storage unit 5 and the memory data in the first system microcomputer 4 storing the unique data of all the discs stored in the magazine match. Thus, it is possible to reproduce and play the track of the desired performance song, and the first system microcomputer 4 determines whether the track performance has ended (step S15).

When the track performance is completed, the memory data in the external storage unit 5 is subsequently identified from the valid data of all the disks stored in the magazine, and the memory play is repeated by the disks having the same valid data, and all the disks in the magazine are read. The playback performance is executed in the order of the disc numbers (steps S11, S12, S15).

The memory play is repeatedly executed until the operator operates the operation keys 14 to cancel the memory play, and by canceling the memory play (step S16), the memory play ends (step S18).

As described above, if there is a favorite song during playback of the disc, it can be stored by one key operation, and can be processed by a simple operation without the need for the conventional 10 key operation. Moreover, it is possible to exchange the discs in the magazine.

Further, as an application of the present invention, by preparing a plurality of memory set keys, for example, only a plurality of JAZZ music can be stored, or only ROCK music can be grouped and a plurality of music can be stored. Grouping them as a group enables multiple memory plays of songs of the same genre.

Also, as for the reproducing and playing method, as described above, the disks are played in order from the disk with the smallest disk number, but conversely, it is also possible to play and play from the disk number with the largest disk number.

[0033]

[Effect of device]

 As described above, the memory play of the audio device according to the present invention stores the unique data of the playback disc, and instead of the conventional memory of the number of the magazine, the memory of the disc, the memory of the disc is stored in the magazine. This has the effect that you can play back and play only your favorite songs even if you replace the key.Also, as shown in the application example, by providing multiple memory areas and multiple memory set keys, you can create more versatile memory play. Playback performance can be performed.

In addition, if there is a favorite song during playback, it can be stored with a single key operation, and the conventional 10-key operation is unnecessary, and the storage operation to the memory is easy. There is also.

Moreover, the memory play function by the autochanger largely depends on the software of the first and second system microcomputers contained therein, and there is an effect that the function can be increased without increasing the cost. It has excellent features such as ready implementation.
