Abstract

PURPOSE:To eliminate the storage of the placement of a disk in a disk player and to improve the operability of the player, by automatically storing disk discriminating information in a memory at the time of disk loading and displaying the information through readout operation. CONSTITUTION:When data is inputted to a control section 11 from an input section 7, the data is discriminated whether it is for writing or reading out by means of a discriminating section 8 and further discriminated 9 about their kinds. After the discrimination, the data is converted into address data and character data. Both data are given to a display section 14 through a driver 15 and a disk number and title are displayed. When a discrimination button is depressed thereafter, character data are written corresponding to the address data of a RAM 13. When the discrimination button is depressed at the time of readout, the character data corresponding to the address data are read out from the RAM 13 and converted into display data. Thus the disk number and title are displayed on the display section 14.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a disc player having a display function for displaying identification information for identifying a disc loaded in the player.

(b) Conventional technology In recent years, with the spread of compact disc players (hereinafter referred to as CD players), continuous playback of multiple discs has become possible. A so-called CD player with an autochanger has been developed. In the new type of CD7'' player, the discs are stacked and stored in a -H magazine, and then this magazine is installed in the player so that it is held at a predetermined standby position in the player. At the time of playback, a predetermined disk is selected from among the disks stacked in the standby position, and this disk is taken out of the magazine and placed on a turntable so that it can be played. -261851 (G11B17/2.6)].

When playing a predetermined song on a $IIcD player, for example, the operator must first know the position from the top of the stacked disks as described above, where the disk containing the song is located. The desired song is played by inputting that number into the player, knowing which song on the disc it is, inputting this number into the player, and performing a playback operation.

As described above, when an operator selects a predetermined song in a new type of CD player, he or she must know the location of the disc that contains the desired song and the track number within the disc of the desired song. Must be. The latter can be easily determined by looking at the index attached to the disc case in which the disc was stored.

However, the operator must remember the number 111 when storing the disc in the magazine. However, when the number of disks stored in a magazine reaches about 10, it is extremely difficult to remember the arrangement of each disk. Therefore, the operator has to write down the layout of each disc on a piece of paper, for example, and is forced to do a lot of tedious work. I had to get it out and check it out.

(c) Problems to be Solved by the Invention The present invention provides a disc player with an autochanger that can continuously play a plurality of discs, so that it is not necessary to memorize the arrangement of each disc loaded in the player. The present invention aims to provide a disc player with an automatic changer.

(b) Means for solving the problem of inter-foot contact In view of the problem of inter-foot contact, the disc player of the present invention includes an information input means for inputting identification information for identifying the disc, and an information input means for inputting identification information for identifying the disc. The device is configured to have a memory means for storing input identification information, a reading means for reading out the identification information from the memory means, and a display amniotic membrane for displaying the identification information read by the reading means.

(E) Operation Identification information for identifying the working disk is stored in the memory means either manually or by the information input means when the disk is loaded. When a predetermined disc is to be parted, the display means displays the farewell information for this disc by operating the reading means.

(f) Example An embodiment of the present invention will be described below.

In Figure 1, (1) is a disc cartridge that supports 10 discs in a stack, (2) is an insertion slot provided in the player body (3) for loading the disc cartridge 111't, and (4) is a playback slot. A display panel for displaying thoughts, etc., (5) an operation button section, and (6) a character input button section for inputting alphabets and numbers from 0 to 9. In some players, after pressing the identification button of the operation button section (, 5), operating the character input button section (6) and inputting the stacking order of the discs (number 8) and, for example, the title, the button is pressed again. When the song button is pressed, the order and title of a given disc are stored in the RAM within the player. for example,
In the second row from the top of the disk cartridge (1)
To set the disc of ``MO x A Orchestra'', first press the identification button to set the player to the disc identification display mode, then operate the character input button (6) to select rS.
By inputting 2POUX MORXXATJ and then pressing the identification button again, the identification information is loaded into the RAM. Above rs2 POUX MORXXAT
” Uchisoto’s rSJ is! 9r indicates that the information is in write mode to be stored in RAM. Therefore, the internal circuit reads a certain "S" and sends r2 POUx
Threaten MORxxATJ with RAMK.

By repeating the above operations, the identification information of the ten disks supported by the disk cartridge (1) is sequentially stored in the RAM.

To read out the identification information stored in this way, press the Seibetsu button in the operation button section (5) to set the player to disc identification display mode, and then press the character input button (6) to read out the identification information stored in this way. ) and input the predetermined disc number. That is, for example, if you want to know the information about the disc stored in the third row from the top of the disc cartridge (1), enter "3" and then press the identification button to find the information corresponding to the disc number "6". The title is R
AM and displayed on the display panel +4).

If you enter "R" instead of the disc number in the length field, the identification information of the discs from the first row up to the tenth row from the top will be displayed.

The player control that operates as described above will be explained with reference to FIGS. 2 and 6.

FIG. 2 is a block diagram showing a control circuit, in which 17+ is an input section for what to do with the character input button section (6), (8) is a data judgment section for deciding whether or not to insert or read data, and 19

OM%u3 is a RAM into which the identification information of each disk is inserted (141 is a display section for displaying the identification information,
The convex portion is a driver for driving the display section t141. Note that the aa RAM t13 is backed up by a charging voltage of a large-capacity capacitor or a battery, and its contents are retained even when the power is cut off.

Next, the operation of the control circuit will be explained with reference to the flowchart of FIG.

When data is input to the control unit Uυ from the input unit-7),
A certain data is transferred to a data determination section (8), and fIJ is determined whether this data is d-in data or read-out data depending on whether or not there is an "S" in the head of this data. When a certain data is determined to be storage data, this data is then processed by the data type determination unit (9).
), where it is divided into a numerical part representing the disc number and a character part representing the title, etc., and converted into address data and character data, respectively. Then, the address data and character data are transferred to the driver and converted into display data, and after the K disk number and title are displayed on the display panel (4), the operator confirms that there are no errors in the disk number and title. By confirming this and pressing the identification button again, character data is written to the address corresponding to the address data in RAM (13).

Incidentally, if there is an error in the disc number and title displayed on the display panel 14), this error 9 can be corrected by re-entering the information.

The above operation is based on the fact that there is an "S" at the beginning of the data input from the input section 17) and the 1st section (8).
This has been an explanation of the operation when J is set, that is, the operation at the time of writing.Next, the read operation when there is no single data "S" will be explained.

Data that does not have "S" at the beginning will be displayed randomly next.
The data is transferred to the specified suI, and flj determines whether the data is rRJ. If the data is not rRJ, this data is transferred to the data type determination section (q), and the numerical part of the data is converted into address data. When reading identification information, you only need to specify the numeric part that represents the disc number, but if you accidentally add character data to the data, the numeric part of the data type f11 (9) may be The part and the character part are separated, and only the address data corresponding to the numeric part is transferred to the control part qυ. However, if there is no numeric part, the control system stops operating and waits for data to be input again. Thereafter, when the identification button is pressed, character data corresponding to a certain address data is read out from the RAM (to), and the certain address data and character data are transferred to the driver 4 and converted into display data. Based on this display data, the disc number and title are displayed on the display panel (4) (see FIG. 4).

Next, at the beginning, there is a message that says ``5Jt-The read data that does not have
If it is "R" instead of a number representing the disc number,
When certain data is transferred to the random display determining unit ulK, a command for random display operation is applied to the control unit (11)K, and address data rAD=IJ is set. Then, the character data corresponding to "AD=1", that is, the character data corresponding to the disc stored in the top row of the disc cartridge (1), is read out from the RAM (13),
These address data and character data are driver <15
Transferred to 1.

Thereafter, this address data and character data are converted into display data, and the title of the top disc is displayed.

When the title of the top disc is displayed, 1 is added to the setting address "AD=1" and the title becomes "AD=1".
2" is set and this address is greater than "10" (determined by the maximum number of discs stored in the disc cartridge)^ is compared, then the title corresponding to rAD=2" is set by the same operation as above. , that is, the title of the second disc is displayed. By repeating this operation, titles corresponding to a total of 10 discs, from the top disc to the disc at the bottom of the disc, are sequentially displayed on the display panel 141, and after that, the set address becomes rAD=11J. It is determined that the random display has occurred, and the random display ends.

As described above, in this embodiment, the discs stored in the disc cartridge can be separated by a simple operation, so it is possible to put the cartridge out of the player and read the title, etc. of the desired disc. It does not require extensive work and can produce extremely excellent effects in terms of operability.

Note that the present invention is not limited to the above embodiments, and various other embodiments are possible. For example, instead of using alphabet keys or numeric keys as a means to input identification information for identifying a disk, for example, by attaching a bar code to the disk case as shown in FIG. It is also possible to input . Alternatively, the identification information may be recorded in an empty pit of the disc, and the identification information may be read directly from this disc.

(G) Effects of the Invention According to the disc player of the present invention, even if a disc is once stored in the player, it is easy to tell what kind of disc it is by simply operating the amniotic membrane. Since the disc can be checked, there is no need to take the disc out of the player and visually check the title, etc. of the disc, and an extremely excellent effect can be achieved in terms of operability.
