Abstract

PURPOSE:To eliminate a waste of time due to a wrong setting by easily setting a disk number, a data number, etc., without any mistake. CONSTITUTION:When a disk 12 is selected in a disk storage section of a tray 13 based on an externally set disk No. whether there is the disk 12 or not is detected and stored and when the selected disk 12 is reproduced based on an externally set music No., TOC data stored on the disk 12 is read and stored. Then it is decided whether the externally set disk No. is already set before or not and when so, the disk No. and music No. are collated with the storage contents to display a wrong set number. Consequently, even if a wrong number is set externally, it can be corrected immediately, so the setting operation is facilitated and a waste of time due to the wrong setting is eliminated.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) This invention provides a disc that selects and reproduces data (for example, songs, etc.) recorded on a desired disc from a plurality of discs. The present invention relates to an autochanger device, and particularly to an improvement in a setting means for selecting and setting desired discs and data.

(Prior art) As is well known, in the field of sound equipment and picture equipment,
In order to achieve high density and high fidelity recording and playback as possible,
Digital recording and reproducing systems that convert information signals such as audio signals and image signals into digitized data, record it on a recording medium such as a disk or magnetic tape, and play it back have become widespread, and recently Nowadays, many compact disc players, video disc players, and the like have appeared on the market.

Among these, compact disc players are not only stationary types that simply play audio signals, but also
Portable type that is small and lightweight for portable use, in-vehicle type that can be installed in a car, disc changer type that automatically exchanges and plays multiple compact discs, and compact Various types have been developed, including a type compatible with the playback of so-called CD-ROMs, which use disks as memory in 91 electronic devices and various υJIB devices, and are being used more frequently.

Here, especially for the disc autochanger type, the disc number is used to specify the desired disc from among multiple discs, and the desired data is designated from among the multiple data (for example, songs) recorded on the disc. By setting the data number and data number by external operation, the disk corresponding to the set disk number is selected from a tray containing multiple disks, and the data corresponding to the set data number is searched from that disk. It is designed so that it can be played back.

This type of disc autochanger allows you to set reservations for multiple sets by storing the externally set disc number and data number as one set in the memory, and sequentially and continuously transfers data in the order set for the reservation. Generally, a so-called program playback function is provided that automatically plays back the program.

FIG. 4 shows the appearance of such a conventional disc autochanger device. That is, a plurality of disks 12 are arranged in a cabinet 11 formed in a substantially box shape.
A tray 13 containing ... is installed so as to be visible from the outside through a window 14 provided in the front panel 11a of the cabinet 11.

Inside this cabinet 11, although not shown, there is a tray 1.
A selection mechanism that selectively takes out a desired disk 12 from the selection head, a playback mechanism that plays back the disk taken out by the selection mechanism, a circuit unit that processes data played back by this playback mechanism and converts it into an audio signal, etc. is installed.

Further, on the front panel 11a of the cabinet 11,
Power switch 15. Numeric key part 16. play key 17,
Bose key 18. Redo key 19. Disk island (number) key 20. Song N (1 (number) key 21 and reservation key 2
Various operation sections such as 23. Various display sections such as disc order and song order display section 24° error display section 25 are 8il! It is set up.

Here, when the operation is started as shown in step S1 in FIG. 5, it is determined in step S2 whether or not the disc Nα and the song order have been set. and,
If it is set (YES), the selection mechanism selects tray 1 corresponding to the set disk station in step S3.
A disk ejecting operation is performed for the third disk storage section.

Thereafter, in step S4, it is determined whether or not the disk 12 is present in the disk storage section of the tray 13,
If the disc 12 does not exist (No), the error display section 25 is turned on in step S5 to display that there is an error in the set disc number. If the disc 12 is present in step S4 (YES), the reproducing mechanism searches for a song corresponding to the set song Nα in step S6.

At this time, it is determined whether a song corresponding to the song Nα set in step S7 exists, and if it does not exist (
No), in step S5, the error display section 25 is turned on to display that there is an error in the set song Nα. Also, if a song exists in step S7 (YES)
In step S8, the playback operation of the song is executed by the playback I structure, and the desired song set here is played.

Thereafter, in step S9, it is determined whether or not the reproduction of the song has ended, and if it has ended (YES), step S10
Then, the disc 12 is returned to the original disc storage compartment of the tray 13 by the transport mechanism.

Then, the process returns to step S2 again, and the next disk N0
and special effects are applied to the settings of the song Nα.

However, in the conventional disc autochanger device as described above, even if there is an error in the set disc Nα, that is, even if the disc Nα is set for a disc storage compartment in which the disc 12 of the tray 13 is not stored, , the selection mechanism takes out the disk 12 from the disk storage compartment, and if it cannot be taken out, it is determined as an error, so that it takes a long time for the user to realize that the set disk number is incorrect. , which takes a considerable amount of time.

In addition, even if there is an error in the set song number, that is, if only six songs are recorded on the selected disc 12 and the seventh song is set as ○, the playback mechanism will The system performs an operation to search for the song corresponding to the set song No. 0, and determines that it is an error if the search is not possible. , it still takes time.

Furthermore, if there is an error in the set disc Nα or song NQ, for example, multiple discs Nα and song Nα
When playing a program with the settings set, the disc autochanger device stops operating when an error is detected, so the program must be restarted from the point at which the operation stops.

Therefore, in order to avoid the above-mentioned inconvenience, the user must remove the disc 1 in the tray 13.
2 and the number of songs recorded on the existing discs 12, etc., which is very inconvenient to handle.

(Problems to be Solved by the Invention) As described above, in the conventional disc autochanger device, it is inconvenient to set the disc NQ and song ~α, and moreover, even if the wrong disc N0 or song Nα is set, This poses various problems, such as the fact that it takes time to figure it out.

Therefore, this invention was made in consideration of the above circumstances, and it is possible to easily perform the setting work of disk numbers, data numbers, etc. without errors, and eliminate wasted time consumption due to incorrect settings. The purpose is to provide an extremely good disc autochanger device.

[Structure of the Invention] (Means for Solving the Problems) That is, the disc autochanger device according to the present invention selects a disc from the corresponding disc storage compartment of the disc storage unit based on the externally set disc number. The first step is to detect and store the presence or absence of a disk in the state.
a second storage means for reading and storing the number of data recorded on a disc selected based on an externally set data number while reproducing desired data from the disc; Determine whether or not the set disk number is a previously set disk number, and if the set disk number is a previously set disk number, store the disk number and data number in the first and second storage means. control means for checking the stored contents and displaying an error in the set number; ! The apparatus is equipped with an erasing means for erasing all or selectively the disc number and data number of @.

(Function) According to the above configuration, the presence or absence of a disk is detected and stored in a state where a disk is selected from within the disk storage section of the disk storage section based on the externally set disk number, and the external While playing a disc selected based on the set data number, read and memorize the number of data recorded on the disc, and when making external settings, confirm that the set disc number was previously set. If the disk number and data number have been set previously, the disc number and data number are compared with the stored contents and an error in the set number is displayed. Even if an incorrect number is set during external settings, it can be corrected immediately, making the setting work easier and eliminating unnecessary time consumption due to incorrect settings.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings. In FIG. 1, the same parts as in FIG. 4 are indicated with the same symbols. The difference here is that a clear key 26, which will be described later, is provided on the front panel 11a of the cabinet 11.

It is assumed that the tray 13 is provided with a disk storage section that accommodates 100 disks 12, and each disk storage section is assigned a number from Disk NQI to Disk No. 100, respectively.

Here, the operation of the disc autochanger device as described above will be explained with reference to the flowcharts shown in FIGS. 2 and 3. First, when the operation is started in step 311, it is determined in step 812 whether or not the disc order and song number have been set. If it is set (YES), step 313
Then, it is determined whether the disk 12 corresponding to the set disk NQ is a disk 12 that has been specified before.

In this case, if the disk 12 has not been designated before (No), then in step 814 the selection mechanism selects
The disk 12 is removed from the disk storage section of the tray 13 corresponding to the set disk Nα. Then, in step S15, it is determined whether or not the disk 12 is present in the disk storage section of the tray 13, and if the disk 12 is not present (No.
), in step 816, the disk Nα is stored in a memory (not shown), and in step 817, the error display section 25 is lit to indicate that there is an error in the set disk NG.

Further, if the disk 12 exists in step S15 (YES), that disk 12 is taken out, and in step 81B, the TO of the disk 12 is
C (Table of Contents) data is read,
In step 819, the number of songs recorded on the disc 12 is stored in the memory.

Then, in step 820, it is determined whether or not a song corresponding to the set song number exists. If the song does not exist (No), in step 817, the error display section 25
lights up to indicate that there is an error in the set song order. Also, if a song exists in step S20 (Y
ES) In step 821, the playback mechanism executes playback of the song, and the desired song set here is played back.

Thereafter, it is determined in step S23 whether or not the reproduction of the above-mentioned surface has been completed, and if it has been completed (YES), step 824
Then, the disc 12 is returned to the original disc storage compartment of the tray 13 by the selection mechanism.

Then, in step 825, the process returns to step S12, and the process waits for the next disc Nα and song Nα to be set.

Therefore, according to the above operation, for the disk 12 in the disk order set for the first time, it is determined whether or not the disk 12 exists in the disk storage compartment of the tray 13 corresponding to the disk Nα. , the determination result is stored in the memory, and if the disc 12 is present, the TOC data of the disc 12 is read and stored in the memory, and then the actual playback operation is performed. become.

Next, the disk 12 corresponding to the disk Nα determined to have been set in the previous step 812 is set in step 812.
The case where it is determined in step 13 that it has been set before (YES) will be explained.

That is, in this case, since the disk 12 has already undergone the above-mentioned process, the presence or absence of the disk 12 in the disk accommodation section of the tray 13 corresponding to the set disk N0 and the TOC data in the presence state are stored in the memory. is stored in Therefore, the disk Nα set in step 826 is compared with the stored contents of the memory, and it is determined whether or not the disk 12 is present in the disk accommodation section of the tray 13 corresponding to the set disk Nα. .

If the comparison results do not match (NO), the error display section 25 is lit in step S27 to display that an incorrect setting has been made. Also, step S26
If the comparison results match (YES), the song order set in step 82B is compared with the stored contents of the memory, and the song corresponding to the set song number is selected from the previously set disk 12. It is determined whether or not it exists.

In this case, if the comparison results do not match (No), the error display section 25 is lit in step 827 to display that an incorrect setting has been made.

Also, if the matching result in step 828 matches (
If YES), the music reproduction operation is performed by the above-described processing after step 814.

Here, in step 812, the disk Nα and the song Na
is not set 1 (No>, step 82
At step 9, it is determined whether or not the disk 12 in the tray 13 has been replaced by the user. If the disk 12 has not been replaced (<No), the process returns to step 812 and enters a standby state, and if the disk 12 has been replaced (
YES), the contents stored in the memory of the disk storage section of the tray 13 corresponding to the disk 12 replaced by the user in step S30 are erased.

To erase the contents of this memory, for example, when erasing the contents stored in the disk 12 of disk Nα53, first set "53" in the numerical key part 16, and then
This is done by operating the clear key 26 after operating the α key 20. Also, if you want to erase all the contents of the memory, use the number 11ff and part 16 to
”, and after operating the disk N (l key 2o), operate the clear key 26.

In the case of program playback in which a plurality of songs are sequentially played, after step 820, the set disk Nα and songs ~α are stored in the memory and reservation settings are made, and when the reservation settings are all completed, e.g. By operating the play key 17, the operations of ejecting the disc 12, searching for two songs, playing back, and returning the disc may be sequentially repeated.

Therefore, according to the above embodiment, the presence or absence of the disc 12 is detected and stored in a state in which the disc 12 is selected from the disc accommodation section of the tray 13 based on the externally set disc Nα, and the externally set music The TOC data recorded on the disc 12 is read and stored in a state in which the disc 12 selected based on the order is played back, and when external setting is performed, the set disc company is one that has been set before. If the disc Nα and song Nα are set previously, the disc Nα and song Nα are compared with the stored contents and an error in the set number is displayed. Even if an incorrect number is sometimes set, it can be corrected immediately, making setting work easier and eliminating wasted time caused by incorrect settings.

In addition, since the storage of the presence or absence of the disk 12, TOC data, etc. is automatically performed when the user sets the disk Nα and the number of songs, there is no need to perform any extra operations for storing the data. .

Furthermore, the memory that stores the presence or absence of a disk and the TOC data is designed so that the stored contents will not be erased even if the power switch 15 is turned off or the outlet is unplugged.
For example, it will be even more effective if it is backed up with a large capacity capacitor or the like.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and can be implemented with various modifications without departing from the gist thereof.

[Effects of the Invention] Therefore, as detailed above, according to the present invention, the setting work of disk numbers, data numbers, etc. can be easily performed without errors, and wasted time caused by incorrect settings can be eliminated. Therefore, it is possible to provide an extremely good disc autochanger device that can perform the following operations.
