Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital audio device, and includes, for example, a CD (compact disc) and an MD (mini disc), and digital data such as music recorded on the CD or MD to another CD or MD
The present invention relates to a dubbing method of an audio device to be dubbed.

[0002]

2. Description of the Related Art Recent audio equipment includes CD and M
It is possible to reproduce and listen to music and the like recorded digitally by incorporating a D drive device. Originally, MD can be written and read (reproduced). Also,
A CD is a recording medium that originally reproduces recorded data, but a CD-R (CD Recordable) is a writable medium. These writable / readable CDs
By using R or MD, the data recorded on the CD is dubbed onto the MD CD → MD or the data recorded on the CD is dubbed onto another CD-R CD → C
DR is possible. Since the CD and MD data are digital data, they can be dubbed any number of times without substantially degrading the sound quality, which is a significant difference from the dubbing of analog data by a magnetic tape or the like.

FIG. 3 is a block diagram showing the basic configuration of a typical audio device. This audio device 10
Is composed of a CD device 11, an MD device 12, a control device (control microcomputer) 13, an operation unit 14, a display unit 15, a digital-analog conversion and amplification circuit (hereinafter collectively referred to as an AMP circuit) 16 and a speaker 17. still,
In the case of stereo signals, 1 to A that processes both left and right signals
It has an MP circuit and a speaker.

The CD device 11 is a CD reproducing device for reproducing digital data recorded on a CD. On the other hand, the MD device 12 is an MD or CD-R recording / reproducing device. When the user drives the CD device 12 by operating the operation unit 14, the digital data recorded on the CD is output to the AMP circuit 16 under the control of the control microcomputer 13 to be digital-analog converted and amplified to a predetermined amplitude. The audio signal is output from the speaker 17. The data being played (song number, song name, etc.) can be displayed on the liquid crystal display panel or EL
(Electroluminescence) Displayed on the display unit 15 formed by a display panel or the like.

Similarly, the user operates the operation unit 14 to set M
When D device is selected, MD is controlled under the control of the control microcomputer 13.
The device is driven. Then, the music data recorded on the MD is reproduced, digital-analog converted and amplified by the AMP circuit 16, and output as a sound signal from the speaker 17. Even in this case, the reproduction data or the like by the MD device 12 is displayed on the display unit 15.

The operation described above is performed by the CD device 11 and the MD.
In the case where the device 12 operates independently, the CD device 11 and the MD device 12 of the audio device 10 are
It is also possible to operate in cooperation as follows. That is,
The CD device 11 is operated as a CD reproducing device and the MD device 12 is operated as an MD (or CD-R) recording device. The CD device 11 reproduces the data recorded on the CD and outputs it to the AMP circuit 16 and outputs the reproduced data to the MD device 12 through the digital signal line 18. Therefore, the MD device 12 records (dubbing) the digital data output from the CD device 11 on the MD or CD-R stored in the MD device 12.

Here, the reproduction data of the CD device 11 is transferred to the MD.
There are two modes for recording (dubbing) on the device 12: constant speed dubbing and double speed dubbing. In the case of constant-speed dubbing, while listening to the reproduced sound in the CD device 11, the MD device 12 records the reproduced sound at a constant speed in the MD or CD-R.
Dubbing is possible while listening to the reproduced sound of the CD device 11. However, since dubbing takes a long time in constant-speed dubbing, the double-speed dubbing makes the reproduction speed of the CD device 11 high and allows the MD device 12 to be dubbed at high speed.
In this case, the reproduced sound of the CD device 11 cannot be heard normally.

In the above-mentioned conventional audio equipment 10, for switching the OTE constant speed / double speed REC (recording or dubbing), a dedicated changeover switch is prepared or a setting menu is provided under the menu hierarchy to set the constant speed / double speed. The REC is selected and stored in the memory inside the control microcomputer 13. O
In the TE operation, when the OTE key is pressed, a preset state is called from the memory, and constant speed / double speed OTE is executed according to the state. On the other hand, for models without a constant speed / double speed setting menu, the constant speed / double speed is selected in the memory hierarchy, and the OT selected by pressing the SET key.
Was running E. For voice output control, double speed O
Only when executing TE (REC), the effect of reducing VOLUME (volume) is applied by applying the attenuation of -12 dB.

FIG. 4 is a flow chart for explaining a conventional dubbing method for audio equipment. First, it is determined whether or not the double speed is set (step S101). If the double speed setting is ON (step S101: Yes), the double speed R
EC is selected (step S2). On the other hand, the double speed setting is O
If it is not N (step S101: No), the constant speed REC is selected (step S103). Next, the recording side, namely M
Recording is started by the D device 12 (step S4), and reproduction is started by the reproducing side, that is, the CD device 11 (step S10).
5). Finally, it is determined whether or not dubbing of all the songs is completed (step S106). When the dubbing of all the songs is finished (step S106: Yes), the dubbing operation is finished, and the dubbing of all the songs is not finished (step S1).
06: No), continues dubbing and waits for the end of dubbing of all songs.

[0010]

However, the above-described conventional audio equipment has the following various problems.
That is, an indicator showing the current setting state was required. Also, it was necessary to enter the menu in advance to make the setting. It was necessary to reset the settings because they returned to the initial settings due to plugging / unplugging the AC outlet, power failure, etc. You cannot operate the remote control when you start it directly from the menu. On models with a limited number of keys, the menu hierarchy became complicated and operation was difficult. Further, in high-speed REC such as 4 × speed or 8 × speed that will be developed in the future, control of audio output is indispensable, and the present system is not sufficient.
