PURPOSE: To obtain a multichanger in which an erroneous selection is corrected quickly by a method wherein a memory which stores a reproduced sound for a prescribed time from a start in a first selection is provided and a control part which outputs the reproduced sound prior to a reproduction output in a second selection and onward and which stores a reproduced sound in a new disk for a prescribed time is provided. CONSTITUTION: A new CD is first housed in a housing part 2, and a number 1 and reproduction are then input. A control part 9 displays them on a display part 11, it sends the new disk to a player 4, and it instructs the reproduction. A reproducing circuit 5 supplies a reproduced signal to a switch 6, a D/A conversion circuit 7 and a memory 8. A sound generating region stores the head part of the reproduced signal for about five seconds via an amplifier 12, and a display is stopped. A conveyance part 3 houses the CD again. After a second operation onward, the number 1 and the reproduction are selected again by an input operation as long as the CD is not replaced, the control part 9 recognizes it as a reselection, and a voice at the head part of a reproduced sound is generated for five seconds. It takes about 20 seconds until the reproduced sound is output since the reproduction is designated. On the other hand, the reproduction from the memory 8 is started instantaneously, and the reproduction can be stopped before the reproduced sound is output in an erroneous selection.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-changer capable of selectively reproducing a plurality of stored discs.

[0002]

2. Description of the Related Art At present, a disc player used in the field of so-called car audio is equipped with one compact disc or mini disc (hereinafter referred to as CD, MD), and the music recorded on the CD or MD is selected appropriately. Reproduction is possible (for the sake of explanation, only reproduction of a CD will be described below. Needless to say, MD can be reproduced as well as CD).

By the way, when it is desired to listen to a song other than the songs included in the CD loaded in the disc player, this CD
It is necessary to discharge the CD once and load a new CD here. At this time, it is necessary to confirm whether or not the music to be listened to is included in the newly loaded CD by referring to the music display or the like written on the surface of the CD. If a CD is loaded without making such a confirmation, the inconvenience will occur only after the reproduction sound of the CD is output and the user realizes that the CD selection was wrong. Therefore, the confirmation work such as the display of the music on the CD before loading the CD in the disc player is essential.

Each of the above-mentioned operations of ejecting a CD from the disc player, confirming the music display of the CD before loading into the disc player, and loading the CD into the disc player is performed on the operation surface (eject) of the disc player. This can be surely done by gazing at the surface of the CD, the buttons, the disc insertion slot, etc.). On the other hand, since this disc player is for car audio, such an operation (CD ejecting operation, C
In some cases, the confirmation operation such as the song display of D and the CD loading operation) are frequently performed. In this case, the attention directed to driving must be temporarily turned on to confirm this operation. I have a problem with.

In order to solve these problems, the following has been considered. Loading multiple CDs (multi-changer) In order to eliminate the above-mentioned operations (CD ejecting operation, CD song display confirming operation, CD loading operation), multiple CDs that you want to hear in advance are loaded in the disc player. I'll do it.
Then, in the case of appropriately selecting the CD in which the music to be listened to is recorded, this can be done by matching the disk selection button to the CD.

Ensuring CD selection (display of disc name) In the above, by selecting the disc selection button for the corresponding CD, CD selection reproduction becomes possible,
Also, by giving this CD a favorite name,
The name can be displayed on the display surface of the disc player,
It is possible to confirm the contents of the CD by looking at this. For example, naming a CD is done as follows. (1) Play the disc you want to name (2) Press the name registration mode (edit mode) button (3) While pressing the character / number button, search for the character or number you want to use for the name (4) Character you want to use If you can find a number or a number, press the letter / number selection button (5) Register the name you entered in this way by pressing the name registration mode button again. These series of operations (1) to (5) are loaded. Do everything about the CD. The registered CD name information is stored in the memory built in the disc player. Also,
For example, in order to display the name of the CD given as described above, by pressing the display button during the performance of the CD, the name given to the CD being played can be displayed on the display unit for a certain period of time.

[0007]

As described above, the disk player used in the field of car audio performs various operations that are frequently performed during the driving of an automobile (e.g., a CD eject operation, a CD song display confirmation operation, etc.). For the CD loading operation), the attention directed to driving must be temporarily turned on to confirm this operation, which causes some problems in terms of safe driving. Therefore, there is a demand for maximizing the time devoted to performing such various operations that are frequently performed while driving a vehicle.
As a solution to solve this problem, as described above,
There are multi-changer and disk name display. Such a solution may reduce some of the time devoted to performing these various actions that are frequently performed while driving a vehicle. However, since the disc name display can only display the name of the CD being reproduced, the inconvenience of realizing that the CD selection error was made only after the CD reproduction sound was output could not be eliminated.

An object of the present invention is to provide a multi-changer which can eliminate the inconvenience of noticing that the CD selection is wrong only after the reproduction sound of the CD is output.

[0009]

In order to solve the above-mentioned problems, the present invention provides a multi-changer having the following structure. A plurality of discs (CDs or MDs) stored (in the disc storage unit 2) are input (input unit 10
In the multi-changer 1 which can be selectively played back (by the operation of.), When each disk (CD or MD) is first played back (by the disk player unit 4), the playback sound of the selected disk (CD or MD) is reproduced. When the memory 8 that stores a memory for a predetermined time (for example, 5 seconds at the beginning of the reproduced sound) from the start of reproduction and each disk (CD or MD) for the second time or later is selected, reproduced sound output (reproduction) of the selected disk (CD or MD) It outputs the reproduction sound (for example, 5 seconds at the beginning of the reproduction sound) of the disk (CD or MD) stored in the memory prior to the sound from the designation until about 3 seconds elapses), and the disk (CD Or, eject the MD and insert a new disc (same as the shelf of the disc storage unit 2 where the ejected CD or MD was stored. Insert accommodating a new CD or MD in the shelf) the new disc (newly accommodated CD
Alternatively, when reproducing the MD, the reproduction sound of the ejected disc (CD or MD) stored in the memory 8 is erased and the newly inserted disc (CD or M) is erased.
D) has a control unit 9 for controlling the memory 8 so as to store the reproduced sound for a predetermined time from the start of the reproduction, and even if an erroneous selection is made during the second or subsequent disk reproduction selection, the erroneously selected disk ( Prior to outputting the reproduced sound of the CD or MD, the disc (C) stored in the memory 9 is output.
A multi-changer 1 which outputs a reproduced sound of D or MD).

The disk storage unit 2 has a plurality of discs (for example, 6 discs).
Each CD can be independently taken out and stored.
It is equipped with a plurality of shelves for storing. In addition, the disc storage unit 2 can be taken out of the multi-changer 1 with the CD stored therein, and can be loaded into a predetermined position in the multi-changer 1 from the outside.

As a result of the disc selection operation performed via the input unit 10, the disc transport unit 3 responds to a disc selection signal (transport control signal) supplied from the control unit 9 from the shelf of the disc storage unit 2. Is taken out, and the taken-out CD is conveyed to the mounting surface of the turntable of the disc player unit 4.

The disc player unit 4 reproduces, tracks forwards, and returns the CD mounted on the turntable in accordance with an operation control signal supplied from the controller 9.
It performs various operations such as stop and pause. Then, when the reproduction operation control signal is supplied from the control unit 9, the disc player unit 4 starts reproducing the CD.

The disk reproducing circuit 5 sends the digital audio signal reproduced and output from the disk player unit 4 to the DA conversion circuit 7 via the switch 6 and supplies it to the memory 8.

When the switch 6 is switched to the disk reproducing circuit 5 side, the DA converting circuit 7 outputs to the amplifier 12 the reproduced analog audio signal obtained by DA converting the digital audio signal output from the disk reproducing circuit 5. To do. When the switch 6 is switched to the memory 8 side, the reproduced analog audio signal obtained by DA conversion of the digital audio signal output from the memory 8 is output to the amplifier 12. The switch 6 is switched by a switching control signal supplied from the controller 9.

The memory 8 is composed of, for example, a RAM. Then, the memory 8 receives the write control signal supplied from the control unit 9 and outputs a digital audio signal corresponding to the disc selection signal output from the disc reproducing circuit 5 (that is, data capable of reproducing the voice for a certain period, for example, 5 seconds). To memory. Further, the memory 8 sends a digital audio signal corresponding to the disk selection signal stored therein to the DA conversion circuit 7 via the switch 6 in response to the read control signal supplied from the control unit 9. Further, the memory 8 erases the digital audio signal stored therein by the erase control signal supplied from the control unit 9.

The control unit 9 controls the operation of the entire multi-changer 1. The control unit 9 identifies the input operation signal supplied from it by the input operation of various keys on the input unit 10, and various control signals (disk selection signal (transport control signal), operation control signal, reproduction operation) corresponding thereto. Control signal, switching control signal, write / read control signal, display control signal) to the disc transport unit 3, disc player unit 4, switch 6, memory 8, and display unit 11, respectively.

The input unit 10 is provided with various operation keys such as reproduction, track feed, track return, stop, pause, disk selection (disk number selection), and ten keys (1 to 10). Then, by inputting various operation keys, an input operation signal corresponding thereto is sent to the control unit 9.

The display unit 11 is, for example, an LCD (liquid crystal element).
In accordance with a display control signal supplied from the control unit 9, for example, various characters such as a disk number and a track number can be displayed, and eight characters can be displayed.

The amplifier 12 supplies to the speaker 13 an audio signal obtained by amplifying the reproduced analog audio signal output from the DA conversion circuit 7 by a predetermined amount, so that the speaker 13 emits audio corresponding to the audio signal output from the amplifier 12. Make a sound.

Next, the operation of the multi-changer 1 having the above-described structure will be described in the order of (1) first playback selection of each disc (2) second and subsequent playback selection of each disc.

(1) When the first reproduction of each disc is selected A new CD is stored in the CD storage shelf of the disc storage unit 2, for example, disc number 1. After that, when "disc number 1" or "playback" is selected by an input operation of the input unit 10, an input operation signal corresponding thereto is supplied from the input unit 10 to the control unit 9. In response to this, the control section 9 identifies this input operation signal as "disk number 1" or "playback" (100, 110 shown in FIG. 2).

As a result, the control unit 9 sends a display control signal to the display unit 11 to display "disk number 1" and "playback". As a result, the display unit 11 displays "disk number 1" and "playback". Around this,
The control unit 9 controls the disc storage unit 2 with respect to the disc transport unit 3.
A disc selection signal indicating that the CD accommodated in the CD accommodating shelf of disc number 1 is conveyed from the disc accommodating section 2 to the disc player section 4 is transmitted. In response to this, the disc transport unit 3 causes the disc number C of the disc storage unit 2 to be C.
The CD is taken out from the D storage rack, and the taken-out CD is conveyed to the mounting surface of the turntable of the disc player unit 4 (this conveying time is 10 to 20 seconds) (12 in FIG. 2).
0).

Next, the control section 9 sends to the disc player section 4 a reproduction operation control signal for reproducing the CD mounted on the turntable. In response to this, the disc player unit 4 starts reproducing the CD of disc number 1 (130 shown in FIG. 2). It goes without saying that the control unit 9 sends the TOC information prior to the reproduction of the CD from the disc player unit 4. The disk reproducing circuit 5 outputs the reproduced digital audio signal obtained by performing the required digital reproduction processing on the digital audio signal reproduced and output from the disk player unit 4 to the DA conversion circuit 7 through the switch 6 and also to the memory 8. Output.

The digital audio signal output from the disc reproducing circuit 5 and supplied to the DA converting circuit 7 via the switch 6 is DA converted by the DA converting circuit 7 and then from the speaker 13 via the amplifier 11. A sound is emitted (140 shown in FIG. 2).

On the other hand, the digital audio signal directly supplied from the disc reproducing circuit 5 to the memory 8 is output during the output period of the write control signal supplied from the control section 9 to the memory 8,
It is written together with the disc number information (disc number 1
The head portion of the reproduced sound of the CD is memorized for 5 seconds) (150 shown in FIG. 2).

When the reproduction of the CD of the disc number 1 is completed in this way, the disc player unit 4 sends to the control unit 9 a signal indicating that the reproduction of the CD of the disc number 1 is completed. In response to this, the control unit 9 determines that the disc number 1
Recognize that the playback of the CD has been completed. Then, the control unit 9 sends a display control signal to the display unit 11 to stop the display of “disk number 1” and “playback”, so that the display unit 11 displays “disk number 1” and “playback”. Is stopped (160 shown in FIG. 2).

Along with this, the control unit 9 causes the disc carrier unit 3 to move the CD with the disc number 1 mounted on the turntable of the disc player unit 4 from the disc player unit 4 to the disc storage unit 2. CD with disc number 1
Send out the transport to the storage rack. Accordingly
The disc transport unit 3 transports the CD placed on the turntable of the disc player unit 4 to the CD storage shelf of the disc number 1 of the disc storage unit 2 and stores it again (FIG. 2).
170).

After that, if necessary, the disk storage unit 2
Eject the CD stored in the CD storage shelf of disc number 1 and replace it with a new CD. In this case, the original data on the CD with the disk number 1 stored in the memory 8 is rewritten by the above-described procedure with the data on the new CD that has been erased or replaced). The control unit 9 recognizes the replacement of the CDs by collating the TOC information (if the verifications match, it recognizes that the CDs have not been replaced, and if the verifications do not match, recognizes that the CDs have been replaced). (180 shown in FIG. 2).

(2) When the second or subsequent reproduction of each disc is selected When the above-mentioned (1) operation of the first reproduction of each disc is completed and the above-mentioned CD is not replaced, the input unit 1
By inputting 0, "disc number 1" and "playback" are selected again. An input operation signal corresponding to this is supplied from the input unit 7 to the control unit 9. In response to this, the control unit 9 identifies this input operation signal as "disk number 1" and "playback", and recognizes that the selection is again (1 shown in FIG. 3).
90).

As a result, the control section 9 sends to the display section 11 a display control signal for displaying "disk number 1" and "playback". As a result, the display unit 11 displays "disk number 1" and "playback". Further, the control unit 9 outputs a read control signal to the memory 8 so that the digital audio signal in which the first 5 seconds of the reproduced sound of the CD having the disk number 1 is stored is output. Further, the control unit 9 can send the digital audio signal output from the memory 8 to the switch 6 (the digital audio signal corresponding to the first 5 seconds of the head portion of the reproduced sound of the CD having the disk number 1) to the DA conversion circuit 7. Thus, the switching control signal for switching to the switch 6 side is output. In this way, the digital audio signal corresponding to the head portion 5 seconds of the reproduced audio of the CD of the disk number 1 stored in the memory 8 is DA converted by the DA conversion circuit device 7 via the switch 6,
Sound is emitted from the speaker 13 via the amplifier 12.

This sound emission from the speaker 13 can be performed significantly prior to the reproduction start of the disc player unit 4 (for example, it takes about 20 seconds from the reproduction designation to the reproduction sound output, while the memory is stored in the memory). Playback from 8 will start playing instantly). As a result, it is possible to know whether or not the wrong selection of the disk is made before playing the CD by listening to the head portion of the reproduced sound emitted from the speaker 13 only for 5 seconds. It becomes possible to promptly eliminate the erroneous selection state (200 to 230 shown in FIG. 3). In the case of erroneous selection, by operating the stop button of the input unit 10, the reproduction of the CD can be stopped before the reproduced sound is output. If the selection is correct, the CD sound can be reproduced again by continuing this state.

[0034]

The multi-changer of the present invention solves the conventional inconvenience of noticing that the disc selection is wrong only after the reproduced sound of the selected disc is output, and the reproduced sound of the disc is output ( It takes about 20 seconds from the playback specification to the output of the reproduced sound) A long time ago, the head of the reproduced sound of this disc is briefly (a certain time from the start of the reproduction of the first song recorded on the disc, for example, about 5 seconds).
Since it is audible, it can be confirmed without changing the line of sight, unlike the system in which the selected disc is recognized by looking at the display attached to the disc. Further, even when the multi-changer of the present invention is used in the field of car audio, due to various operations that are frequently performed during the driving of the automobile (disk ejecting operation, disc song display confirming operation, disc loading operation), It eliminates the drawback of having to frequently pay attention to driving to check this operation, minimizes this time, and requires only disk selection, so safe driving can continue. Can contribute significantly.
