Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a disc reproducing apparatus including a changer capable of selecting and reproducing a required one from a plurality of discs set in a plurality of disc mounting portions of a turret tray.
[0002]
[Prior art]
In recent years, DVD (Digital Versatile Disc), a new medium, has attracted attention because it has dramatically improved image quality and can record a large amount of information compared to conventional media. ing. This DVD can digitally record a video signal and an audio signal for a long time on a disk having the same diameter of 12 cm and a thickness of 1.2 mm as a CD (compact disk). Also, in recent years, rather than setting discs one by one in the device, the required number of discs are set in advance in the disc mounting portion of the turret tray, and desired ones are sequentially selected from those discs. A reproducible changer can be attached to the above-described disk reproducing apparatus.
[0003]
In a disc playback apparatus equipped with the above changer, when the disc is replaced and played back, the number of the disc number in the turret tray on which the disc set in the disc mounting portion is to be played is operated by operating a key such as a remote control transmitter. It is necessary to specify by. Therefore, conventionally, when a disc number to be played is specified by operating the numeric keys on the remote control transmitter, a small space in the lower left corner of the monitor screen is blanked to set the specified disc number to a numeric value. It is trying to display.
[0004]
[Problems to be solved by the invention]
However, the conventional means for displaying the disk number of the disk to be played is very difficult to see a small numerical value in the lower left corner of the monitor screen, and the disk with the specified disk number is placed at the playback position. Therefore, when the turret tray is rotated, the display on the display unit is sequentially changed to the disk number that passes through the reproduction position, so that it is more difficult to see. For this reason, the displayed disk number cannot be accurately confirmed from a location relatively distant from the monitor screen. Moreover, since the display time is as short as about 2 to 3 seconds, the display may disappear before confirming whether the specified disk number is correct. In such a case, the numerical key must be operated again to specify the disk number again, which is very troublesome.
[0005]
If the stop key is operated while the disc is being played, the video display is temporarily stopped and the menu is displayed, but the disc number is not displayed. This disc number is displayed for the first time when the playback track number is specified and entered based on the menu display, so operations such as selecting the menu after knowing the disc number cannot be performed. Is very inconvenient.
[0006]
In addition, as a conventional means for displaying the disk number, when the turret tray is opened, the disk number of the disk that is outside the apparatus and the disk number of the disk that is in the apparatus are displayed in a different color. There is known a turret tray type multi-disc reproducing apparatus (refer to Japanese Patent Laid-Open No. 8-45161). However, this display means is provided separately with a display unit such as a color liquid crystal display tube, and displays numerical values for all the disk mounting parts of the turret tray on the display part, and the disk mounting part and the device outside the apparatus. In order to distinguish it from the disc loaded part in the disc, it is displayed in a different display color. Since it is necessary to provide a display unit and a display control device separately, it is expensive and the entire device is enlarged.
[0007]
Therefore, the present invention has been made in view of the above-described conventional problems, and it is possible to reliably set the disk number of a disk designated for reproduction from a relatively remote place while using a simple and inexpensive structure using an existing structure. It is an object of the present invention to provide a disc reproducing apparatus including a changer that can be displayed so as to be visually recognized.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing a schematic configuration of a disk reproducing apparatus provided with a changer according to an embodiment of the present invention. In the figure, a changer 1 has a turret tray 3 rotatably provided around a rotation shaft 4 in a housing 2, and a plurality of discs (five examples are shown in the figure) mounted on the turret tray 3. The parts 3a to 3e are provided on the concentric circles at equal intervals. A disc 8 such as a DVD can be inserted and set in each of the disc mounting portions 3a to 3e. The turret tray 3 is rotated by the turret tray driving unit 7 in the clockwise direction in the figure, for example. In addition, disk numbers are set in the disk mounting portions 3a to 3e along the rotation direction of the turret tray 3, and in the vicinity of each of the disk mounting portions 3a to 3e in the turret tray 3, for example, A disk number constituted by the number of slits and the interval is formed and displayed.
[0019]
The housing 2 of the changer 1 is provided with a disk number detection unit 9 for detecting the disk numbers of the disk mounting units 3a to 3e positioned at the reproduction position, for example. The disk number detection unit 9 optically detects, for example, the disk number formed and displayed in the turret tray 3 in the vicinity of the disk mounting units 3a to 3e.
[0020]
The control unit 10 composed of a microcomputer controls the entire disk reproducing device by the CPU executing a control program stored in the ROM based on various data stored in advance in a built-in RAM. In this embodiment, a remote control transmitter 11 is used as the input unit of this disc reproducing apparatus. The remote control transmitter 11 includes at least ten numeric keys 12, a reproduction key 13, and a stop key 14, and other keys and the like are not shown.
[0021]
The remote control transmitter 11 is characterized by specific ones corresponding to the respective disk numbers of the disk mounting portions 3a to 3e of the changer 1 among the ten numerical keys 12 (in this embodiment, the numbers 1 to 5). 5) are pre-set corresponding to each disk number, for example, 1 is red, 2 is yellow, 3 is blue, 4 is green, 5 is white, etc. And light-emitting diodes (not shown) are arranged in close proximity to each other corresponding to each of these numeric keys. The five specific numerical keys 12 for designating the above-described disk numbers are displayed in a light-emitting manner so that the corresponding light-emitting diodes are turned on and visible from the outside when pressed for the purpose of designating the disk numbers. The
[0022]
The transmission signal from the remote control transmitter 11 is received by the remote control receiving unit 17 and then input to the turret tray driving unit 7 and the control unit 10. When a disc number is designated by operating a predetermined numeric key 12 of the remote control transmitter 11, the turret tray drive unit 7 rotates the turret tray 3 and sets it to the disc mounting portions 3a to 3e of the designated disc number. The disk 8 is positioned at the reproduction position. When the control unit 10 receives a playback command signal from the remote control transmitter 11 by operating the playback key 13, it drives the decoder 18 to demodulate the image information recorded on the disk 8 at the playback position, and then An image is displayed on a monitor 19 such as a cathode ray tube of a receiver. The control unit 10 monitors a required display color signal from the OSD (on-screen display) IC via the superimposing circuit 21 when a signal of the disc number to be reproduced is input from the remote control transmitter 11. The output is output to 19, and the required display is controlled. Details thereof will be described later.
[0023]
Prior to the description of the display control process by the control unit 10, the display control process by a microcomputer (not shown) which is a control means built in the remote control transmitter 11 will be described with reference to the flowchart of FIG. The microcomputer constantly monitors whether or not an operation for designating and inputting a disk number has been performed by operating specific five numeric keys 12 (step S21). When it is determined that the operation has been performed, an input operation is performed. The light emitting diode corresponding to the numeric key 12 is turned on, and the numeric key is emitted and displayed on the outside (step S22). After that, the microcomputer monitors the elapse of a predetermined time such as 10 seconds (step S23), and continues the light emission display of the numeric key until the elapse of the predetermined time, When it is determined that a certain time has elapsed, the light emitting diode is turned off and the light emission display of the numerical key 12 is stopped (step S24).
[0024]
Next, display control processing by the control unit 10 will be described with reference to the flowchart of FIG. The control unit 10 constantly monitors whether or not a signal specifying the disc number to be reproduced is input from the remote control receiving unit 17 (step S1), and when it is determined that the specified signal is input, the specified disc number When it is confirmed that the disc 8 is positioned at the reproduction position, the OSD IC 20 is instructed to output a display color signal corresponding to the designated disc number.
[0025]
That is, when a signal designating a disk number is transmitted from the remote control transmitter 11, the turret tray driving section 7 rotates the turret tray 3 in a predetermined direction based on the designation signal, and the disk number detecting section 9 performs the designated disk. When the numbered disc 8 has reached the reproduction position and outputs a detection signal, the turret tray driving unit 7 stops the turret tray 3 when the detection signal is input, and the control unit 10 detects the detection signal. When it is confirmed that the disk 8 having the disk number designated by the input is positioned at the reproduction position, the OSD IC 20 is instructed to output a display color signal corresponding to the disk number.
[0026]
Therefore, when the disk 8 having the designated disk number is positioned and stopped at the reproduction position, the screen of the monitor 19 is displayed in a color set in advance corresponding to the disk number (step S2), and this solid display is displayed on the disk. 8 is continued until the reproduction operation No. 8 is started. Thereby, the user can surely visually recognize the color displayed on the entire screen of the monitor 19 even from a relatively distant place from the monitor 19, and the display color of the monitor 19 and the numeric keys of the remote control transmitter 11 at hand. By comparing with the color colored by 12, it is possible to accurately confirm that the disk number designated by itself and the disk 8 of that disk number have been positioned at the reproduction position.
[0027]
In addition, in this embodiment, the numerical key 12 operated for designating the disk number is displayed in a light-emitting manner, so that the user can accurately confirm the numerical key 12 operated by the user and the numerical value displayed in the light-emitting display. By comparing the coloring of the key 2 with the color displayed on the screen of the monitor 19, it is possible to more accurately confirm whether or not the disk number has been specified by mistake.
[0028]
In addition, since the display of the disk number is performed using an existing monitor 19 and OSD IC 20 that are generally provided in this type of disk playback device, special configurations such as a liquid crystal display and a display control device are separately provided. There is no need to provide it, and it is possible to cope with this by simply changing the control program and control data of the control unit 10, and the above display control can be performed with a simple and inexpensive configuration.
[0029]
Subsequently, the control unit 10 determines whether or not the selection of the disk number has been changed by the user (step S3), and when a signal specifying a different disk number is transmitted from the remote control receiving unit 17, the same as described above. When it is confirmed that the disk 8 having the designated disk number has been positioned at the reproduction position, the display is changed to the color corresponding to the changed disk number on the screen of the monitor 19 and displayed solidly. Control as follows. As a result, the user can accurately confirm that the disk 8 of the disk number designated by changing is positioned at the reproduction position.
[0030]
When the reproduction command signal transmitted from the remote control transmitter 11 is input by operating the reproduction key 13, the control unit 10 drives the decoder 18 to reproduce the image information recorded on the disk 8 at the reproduction position. While the video is displayed on the monitor 19, as shown in FIG. 4A, the reproduction display mark 22 is displayed with the color signal output from the OSD IC, that is, the color set to the disk number of the selected disk 8. The superimposing circuit 21 is controlled so as to be superimposed on the video display. Thereby, the user can confirm the disc number selected by himself / herself by comparing the display color of the playback display mark 22 with the color of the numerical key 12 even during the playback operation.
[0031]
During the reproduction operation of the disc 8, the control unit 10 always monitors whether or not the stop key 14 has been operated (step S6), and the stop key 14 is determined until it is determined that the reproduction operation has been completed (step S12). When it is determined that it has been operated, the decoder 18 is instructed to stop the video display, and as shown in FIG. 4B, the superposition circuit 21 is controlled and output from the OSD IC 20. The color signal is displayed as the background color, and the menu information is superimposed and displayed on the background color (step S7). Therefore, the user can accurately confirm the disc number selected by the user when the stop key 14 is operated by comparing the background color of the screen of the monitor 19 with the coloring of the numerical keys 12 of the remote control transmitter 11 at hand.
[0032]
Subsequently, the control unit 10 determines whether or not the user has operated the remote control transmitter 11 based on the menu display on the monitor 19 (step S8). If there is any instruction input, the control corresponding thereto is performed. The process is performed (step S10). On the other hand, when it is determined that there is no instruction input until a predetermined time elapses (step S9), the decoder 18 is instructed to resume the video display, and the video display is performed. The reproduction operation is continued until it is determined that the reproduction operation has been completed (step S12).
[0033]
In the above embodiment, the disc 8 on which image information is recorded has been described as an object. However, the present invention is also applied to a compact disc reproducing device on which acoustic information is recorded, and the above description has been given. Similar effects can be obtained.
[0034]
【The invention's effect】
As described above, according to the disc reproducing apparatus provided with the changer of the present invention, when the disc number is designated and input from the input unit, the monitor screen is displayed in a preset color corresponding to the disc number. Compare the display color of the monitor that is displayed on the entire screen of the monitor and can be reliably seen from a relatively remote location with the color that is colored on the numeric keys of the input section. Thus, the designated disk number can be confirmed accurately. Further, as a hardware configuration, an existing monitor provided in a general disk reproducing device and a display color control unit such as an OSD IC can be used, so there is no need to provide a special configuration separately. Therefore, it is possible to make the configuration simple and inexpensive.
