Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape recorder, an MD
It is related to audio equipment that can record and play back, etc.
In particular, it relates to setting of a recording level at the time of recording and a reproduction volume at the time of reproduction.

2. Description of the Related Art Conventionally, an audio device such as a tape recorder or an MD capable of recording and reproduction requires a recording level volume for setting a recording level at the time of recording and a reproduction volume for determining a volume at the time of reproduction. Was. If two of these regulators are independently provided, there arises a problem that the number of parts increases and the size of the device increases. For this reason, it is conceivable that the recording volume and the playback volume may be shared by a single mechanical volume.In this case, when the recording is performed by setting the optimum recording level at the time of recording, and then setting the playback mode, Since the playback volume is determined by the volume set at the time of recording, there is a problem that the playback is performed at an unintended volume.

[0002]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and enables the recording and playback level settings to be independently adjusted with a single volume. is there.

[0003]

SUMMARY OF THE INVENTION The present invention has a recording level control circuit for setting a recording level of an input signal, and a reproduction level control circuit for controlling a reproduction volume. A reproducible audio device has a single electronic volume for setting a recording level and a reproduction volume, and a memory for storing digital data indicating the recording level and the reproduction volume set by the electronic volume, respectively. When set to the recording mode or the reproduction mode, the digital data indicating the recording level or the reproduction volume stored in the memory is called, and the recording level control circuit or the reproduction level control circuit uses the immediately preceding recording level or It is characterized in that it is set to the playback volume.

Further, the present invention is characterized in that when the electronic volume is operated during a recording mode or a reproducing mode, a new recording level or a new reproducing level is stored in the memory.

Embodiments of the present invention will be described below with reference to the drawings. Each of the drawings shows an embodiment of a minidisc (MD) capable of recording and reproducing using the present invention. FIG. 1 is a block diagram, and FIG. 2 is a flowchart showing the operation of the present invention. In FIG. 1, reference numeral 1 denotes an MD recording / reproducing apparatus, and 2 denotes an MD in which a magneto-optical disk 3 is built.
A cartridge 4 is a spindle motor for rotating the disk 3, and a pickup 5 is for recording and reproducing music information on the disk 3. Under the control of the control circuit 6, the MD recording / reproducing apparatus 1 is set to a recording mode or a reproducing mode, and recording / reproducing is performed.

Reference numeral 7 denotes an audio signal input terminal, 8 denotes a recording amplifier, 9 denotes a recording level control circuit for controlling a recording level at the time of recording, and 10 denotes a recording circuit for recording an audio signal on the disk 3 via the pickup 5. It is.

Reference numeral 11 denotes a reproduction circuit for reproducing music information read from the disk 3 by the pickup 5, 12 a reproduction amplifier for amplifying the reproduced music information signal, and 13 a reproduction level control circuit for controlling the reproduction level of the reproduction amplifier 12. , 14 are output terminals for outputting a reproduction signal.

Reference numeral 15 denotes an electronic volume for setting a recording level and a reproduction volume. The electronic volume 15 is constituted by, for example, a rotary encoder, and the rotation of a knob is transmitted to the control circuit 6 as an electric signal. Alternatively, the playback volume is set. Reference numeral 16 denotes a memory in which a recording level or a reproduction volume value set by the electronic volume 15 is stored. The memory 16 is configured to be able to independently store digital data indicating a recording level or a reproduction volume.

Next, the operation of the acoustic device according to the present invention will be described with reference to FIG.
This will be described according to the flowchart shown in FIG. First, in step 1, it is detected whether or not the mode is the stop mode. If it is not the stop mode, it is determined in step 2 whether the recording mode is set or the reproduction mode is set. When it is detected in step 2 that the recording mode has been set, digital data indicating the recording level stored in the memory 16 is read out by the control circuit 6 in step 3, and the recording level control circuit 9 performs recording in accordance with this data. The amplifier 8 is controlled, and a predetermined recording level is set in step 4. Thereafter, it is determined in step 5 whether the electronic volume 15 has been operated by the user and the recording level has been changed. When the recording level has been changed, the recording level control circuit 9 controls the recording level of the recording amplifier 8 under the control of the control circuit 6 in step 6. Thereafter, the digital data of the recording level changed in step 7 is stored in the memory 16.
Is stored. The processing from step 5 to step 7 is repeated until it is detected in step 8 that the stop mode has been set. As a result, the memory 16 stores digital data indicating the finally set recording level value. Will be done.

On the other hand, when it is determined in step 2 that the reproduction mode has been set, digital data indicating the reproduction level stored in the memory 16 is read out by the control circuit 6 in step 9 and the reproduction level control is performed in accordance with this data. The circuit 13 controls the reproduction amplifier 12, and at step 10, a predetermined reproduction volume is set. Thereafter, it is determined in step 11 whether or not the user operates the electronic volume 15 to change the playback volume. When the reproduction volume is changed, the reproduction level control circuit 13 controls the reproduction volume of the reproduction amplifier 12 under the control of the control circuit 6 in step 12. Thereafter, the digital data of the reproduction volume changed in step 13 is stored in the memory 16. The processing from step 11 to step 13 is repeated until it is detected in step 14 that the stop mode has been set. As a result, the memory 16 stores digital data indicating the finally set playback volume value. Will be done.

At this time, as described above, since the memory 16 is configured to be able to independently store digital data indicating the recording level or the reproduction volume, the recording before the stop mode is set. The latest value of the digital data of the level or the reproduction volume is stored in the memory 16.

[0012]

As described above, the audio equipment according to the present invention is provided with the memory for storing the digital data indicating the recording level and the reproduction volume set by the electronic volume, respectively, when the recording mode or the reproduction mode is set. By calling the digital data indicating the recording level and the playback volume stored in the memory, respectively, to set the recording level or the playback volume immediately before, the recording level and the playback volume are set by a single volume. It can be carried out.
