BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 shows a disk player 10 of a car audio device for a vehicle according to an embodiment of the present invention. The disc player 10 has a horizontally long opening 11 at a front panel on the front side thereof, and the tray 12 can be pulled out and stored by the opening 11. Then, a disk 13 constituting a recording medium is placed on the tray 12. A plurality of reproduction buttons 14 are arranged at the front end of the tray 12 and at the upper end thereof. These playback buttons 14 indicate the type of disc to be played and also serve as a close button for instructing the tray 12 to be pulled in. Here, three reproduction buttons 14 are provided, and DVD, SACD, and CD are displayed in order from the left.
[0018]
FIG. 2 schematically shows such a disk player system, in which a turntable 18 on which the optical disk 13 is rotatably mounted is provided. The turntable 18 is driven to rotate by a coaxial motor 19 disposed below the turntable. Further, a motor drive circuit 20 for driving the motor 19 is provided. An optical pickup 21 is arranged on the side of the turntable 18 so as to be movable in the radial direction of the disk 13. The optical pickup 21 is connected to a signal reading circuit 22. The signal reading circuit 22 is connected to a signal decoding device 23, which outputs an audio signal or a video signal.
[0019]
The motor drive circuit 20, the signal reading circuit 22, and the signal decoding circuit 23 are respectively controlled by a system control device 26. Note that the system control device 26 is provided with a calculation means including a CPU. A storage device 27 is connected to the system control device 26. Further, a format selection input device 28 is provided so as to be connected to the system control device 26. The input operation section of the format selection input device 28 is constituted by the reproduction button 14.
[0020]
In the above configuration, when the optical disc 13 is reproduced by the disc player 10, the media format is selected by the reproduction button 14 constituting the input operation unit of the format selection input device 28. That is, the reproduction button 14 is selected in accordance with the type of the disk 13, and thereafter, the tray 12 is pulled into the optical disk player 10 by a pull-in command of the reproduction button 14. Then, the format is stored in the storage device 27, and at the same time, the disk 13 is set in the reading device by the motor drive circuit 20 and rotated to be in a reading state.
[0021]
Next, the signal on the disk 13 is read by the optical pickup 21. The disc player 10 detects the media format by the system controller 26 according to the format stored in the storage device 27. If there is a format that can be read by the detection operation, the signal in the disc 10 is read, decoded by the signal decoding device 23, and output as audio or video to the outside of the disc player 10.
[0022]
FIG. 3 shows a media format discriminating operation in such an operation. That is, the format selected by the play button 14 of the format selection input device 28 is first set. Then, based on this format, a detection process for reading the disk 13 is performed. If the format is written on the disk 13, the read operation of the signal is performed. On the other hand, if the set format is different from the format of the disc 13, it is determined whether or not there is another reproducible format, and another reproducible format is set. Is repeated. If there is no other reproducible format, signal read error processing is performed.
[0023]
Therefore, according to such a disc player, if the type of format selected by the play button 14 matches the disc 13 before the disc 13 is inserted, the discriminating operation is performed first. The reading operation of the signal is started upon coincidence. Therefore, the time from the insertion of the disk 13 to the reproduction of audio and video is significantly reduced. Even if the selection operation by the play button 14 is erroneously pressed and the play button 14 of another format is pressed, another playable format is set based on the flowchart shown in FIG. Performs a signal reading process there. Therefore, even if the format selection operation by the reproduction button 14 is erroneous, the reproduction is not disabled.
[0024]
Next, a second embodiment will be described with reference to FIGS. In this embodiment, as shown in FIG. 4, a slot 32 is formed in the front panel of the disc player 10, and the disc 13 is inserted into the slot 32. When the disk 13 is inserted, the loading roller disposed inside and above and below the slot 32 draws the disk 13 to perform a reproducing operation.

A selection knob 33 is provided. The user inserts the disc after selecting the disc format to be reproduced by the selection knob 33. Then, the disc is automatically loaded, the disc format is determined in the order shown in FIG. 5, and the reproduction is started.
[0026]
When a DVD is selected by the format selection knob 33, a format determination operation is performed in the order of DVD detection processing, SACD detection processing, and CD detection processing. When the SACD is selected by the format selection knob 33, the discriminating operation is performed in the order of SACD, DVD, and CD. When a CD is selected by the format selection knob 33, the discriminating operation is performed in the order of CD, DVD, and SACD.
[0027]
Next, a third embodiment will be described with reference to FIGS. In this embodiment, as shown in FIG. 6, a slot 32 is formed in the front panel of the disc player 10, and the disc 13 is inserted through the slot 32. This disc player is not provided with an input means such as a play button 14 and a format selection knob 33 for a user to designate or select a format. That is, in a multi-disc player capable of reproducing DVDs, SACDs, and CDs, the format of a previously reproduced disc is stored in a memory or storage device 27 connected to the CPU of the system control device 26 shown in FIG. The disc format is preferentially discriminated according to the procedure shown in FIG. 7 and reproduction is performed.
[0028]
If the previously reproduced disc 13 is a DVD, the discriminating operation is performed in the order of DVD, SACD, and CD. If the disc used last time is an SACD, the format discriminating operation is performed in the order of SACD, DVD, and CD. If the disc used last time is a CD, the discriminating operation is performed in the order of CD, DVD, and SACD.
[0029]
Therefore, according to such a discrimination method, the format used last time is stored without the user giving any information to the disc player 10 by the play button 14 or the format selection knob 33 and the like. Is performed based on the format. Therefore, particularly when repeatedly reproducing the same type of disc, the time from insertion of the disc to reproduction of audio and video is reduced, and an extremely practical format selection operation is performed.
[0030]
Next, another embodiment will be described with reference to FIGS. The shape of the disc player 10 of this embodiment is the same as that shown in FIG. That is, here, there is no input means for the user to specify or select the format, such as the reproduction button 14 and the format selection knob 33.
[0031]
The CPU incorporated in the system control device 26 shown in FIG. 2 stores the format used each time the disc player is used, and the CPU calculates the weight based on this format. Processing is performed, and the result of performing the weighting operation processing is stored in the storage device 27. Table 1 shows the contents of the weight variables stored by the storage device.
[0032]
[Table 1]

[0033]
As described above, in the present embodiment, in a multi-disc player capable of reproducing DVDs, SACDs, and CDs, when a disc 13 is inserted, as shown in FIG. The disc format is determined according to the determination order, and the reproduction is started. That is, as shown in FIG. 8, the detection processing of the format with the heaviest weight is performed first, the detection processing of the second heaviest format is performed, and then the detection processing of the lightest format is performed. Therefore, the probability of shortening the time from the insertion of the disc to the reproduction of the audio and video becomes very short.
[0034]
FIG. 9 shows an operation of weighting the weight variables shown in Table 1 by the CPU of the system control device 26 shown in FIG. Here, for example, when an SACD is reproduced as the disc 13, it is determined whether or not the weight coefficient of the SACD is the maximum value that can be set in the register. If not, 1 is added to the weight coefficient of the SACD. On the other hand, when the weight coefficient of the SACD is the maximum, it is determined whether both the weight coefficient of the DVD and the weight coefficient of the CD are the minimum values that can be set in the register. Subtract 1 from the weighting factor. When the weight coefficient of the DVD and the weight coefficient of the CD are the minimum values, the state is kept as it is. By such a process, each time the disc 13 is reproduced, the weight coefficient of the disc format can be weighted according to the use history. Therefore, by using such weighting variables, it is possible to shorten the time from the insertion of the disc to the reproduction of audio and video based on the flowchart shown in FIG.
[0035]
The invention included in the present application has been described above with reference to the illustrated embodiment. However, the invention included in the present application is not limited to the above embodiment, and various modifications may be made within the technical idea of the invention included in the present application.
