JPS60246062A - Remote control device for disk reproducer - Google Patents

Abstract

PURPOSE:To perform the play of plural disks or a single disk with a single disk reproducer by discriminating the digit key data obtained before a music number designation key is pushed as a disk number and as a specific disk when said designation key is pushed. CONSTITUTION:The digit key data, the program key data and the play key data are supplied and detected by a key input detection circuit 17. An input data discrimination circuit 18 checks a disk key input or a music key input. The output of the circuit 18 is divided to a disk input set/display circuit 19 and a music input set/display circuit 20 respectively. These circuits 19 and 20 display the input data to a display and also set their action modes, then output the data to a data memory circuit 21. Thus it is possible to perform easily the remote control through a single remote control device for both disk reproducers that can play plural disks and just a single disk, respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a remote control device for a disc playback device capable of playing a plurality of discs.

Conventional Structure and Problems An optical disc player capable of playing multiple discs has been commercialized.

Figure 1 shows a part of the optical disc playback device. 1 is a disc case, 2 is a disc, 3 is a gear notched in the disc case 1, 4 is a traverse, 5 is a disc clamper, and 6 is a disc case. Turntable, 7 is an optical bisok asog, 8 is a disk closing arm, 9 is a shaft, 10 is a shaft for moving the traverse 4, 11.
12 is a fixture for the shaft 10.

The operation of the optical disc playback device having the configuration of F is explained below.When one disc 2 is designated for play among the several dozen discs contained in the disc case 1, the traverse 4 moves the disc 2. The disc loading arm 8 moves toward the disc case 1 and grabs the disc 2. Then, while holding the disc 2, the disc loading arm 8 takes it into the traverse 4 and places it on the turntable 6.

Then, the disc 2 placed on the turntable 6 is
It is firmly fixed to the turntable 6 by the disc clamper 6 and begins to rotate. The optical pig-up 7 takes out the signal recorded on the disk 2, and the Wji silkworm starts to read 1.

There is a key-operated remote control device as shown in FIG. 2 as a remote control device for instructing the operation of the optical disc playback device as described above.

In FIG. 2, 13 indicates a remote control device, 13a indicates part of the numbers 1 to O, and 13b indicates disc specification "0ISC" and song specification "Track".

Part of the program key such as time specification “Time”’ is 13
C eliminates a part of the playing key of "Play" and "Pause".

14 indicates the signal oscillation part. To explain how to operate the keys of this remote control 13, for example, if you want to play from 4 minutes to 6 seconds of the third song of the 12th disc, press "DISC""1". 2”, “Track”
+3".

“Time”+4 ”, +ITime””5”
lI6″T, press the I (lil) key for “Play”. In other words, before pressing the number key part 13a, be sure to press one of the program key parts 13b that determines what number key that key is. Start playing.

Next, if you want to play a program with several discs, let's say Q, J, 12 discs 1] and 34 discs 1-1 as a program iii.
5, press “DISC” “t” “2”, “mem”
ory'″”DISC”” 3 ” +4 ” , ”
``memory'' and ``Play'' press each key to play.

However, in the above-mentioned device that can play multiple discs by remote control with key operations, when remotely controlling a normal disc playback device that can play only one disc, the disc selection key "DISC"
′, the operation was difficult to understand and easy to make mistakes, so there was a problem that it could not be shared.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional problems, and an object thereof is to provide a remote control device that can control both a disc playback device that can play a plurality of discs and a disc playback device that can play only one disc. do.

Structure of the Invention The present invention eliminates the disc designation key and determines the number of discs by the IIFi number at which the song designation key is pressed, thereby making it possible to use it even in a disc playback device that can play only one disc.

DESCRIPTION OF THE EMBODIMENT FIG. 3 shows a remote control device in an embodiment of the present invention.

In FIG. 3, reference numeral 16 indicates a remote control device, 16''a indicates a part of the numerical keys, 15b indicates a part of the program keys, 15c indicates a part of the performance keys, and 16 indicates a signal transmitter.

To explain the key operation method on the remote control device 16 as described above, for example,
When playing from minute 56 seconds, "1" a2 ""
Track” “3” “Time””4”
, “Time” “5” I+6” “Pla
y" in order to start. In this case, before the "Track" key for specifying the song number is pressed, press the number key 16a.
When any of these is pressed, it is always recognized as a disc voice number.

Next, if you want to play a program for several discs, for example, the 12th disc and the 34th disc 1, use the following commands: "1", "2", memory7", +
3 ” 4 ”.

The keys "memory" and "play" are pressed in this order, and the number key before the "Track" key for designating the song number is determined to be the key for designating the disc number, and the performance is started.

When only the song number designation key "Trock" is pressed, for example, in the case of "Track", "2", or "Play", the performance starts from the second track of the first disc.

That is, if the 9-track number designation key "Track" is suddenly pressed without pressing the number key portion 15a, the performance is fixed to the first performance on the disc.

Next, when playing on a disc playback device that can only play one disc using this remote control device 15, for example, two discs can be played.
J Karasai, which is played from 3 minutes 45 seconds into the song, is ``Track''''``2''``Time'' ``3
” “Time”n 4 ” It s It, *
You can start playing 7iii with a simple operation of pl ayI+.

As described above, according to this embodiment, the disk number selection key "DISC" is eliminated, and the song number designation key "Tr" is used.
The initial number is determined by determining the entire disc number of the late key data before "ack" is pressed, or by determining that it is the first track number on the disc when the track number designation key "Track" is pressed without entering numerical key data. The remote control of both a disc playback device capable of playing one disc and a disc playback device capable of playing only one disc can be controlled by easy-to-understand operations, and one unit can be used in common.

FIG. 4 is a circuit diagram of the disk reproducing apparatus of the above-mentioned example, and FIG. 6 is a flowchart showing its operation.

4 and 6, 17 is a key human power detection circuit;
Reference numeral 18 designates a disc and music input data discrimination circuit, 19 a disc input setting/display circuit, 20 a surface input setting/display circuit, and 21r/i data memory 1 circuit.

To explain the operation below, each of numerical key data, program music data, and performance key data is input detected by 17 key human power detection circuits, and input data discrimination circuit 1r61
At step a, it is checked whether it is the disc key input or the song key input, and the signals are distributed to each of the 19 disc input setting/display circuits and the 20 surface input setting/display circuits and output. Each of the input setting/display circuits 19 and 20 displays input data on a display, sets the respective operation modes, and outputs the data to the data memory circuit 21 for storage.

It goes without saying that the remote control 16 of the above embodiment may have any key arrangement and name as long as they have the same functions.

Effects of the Invention The present invention eliminates the disc number selection key and determines that the numerical key data before the song number designation key is pressed is the disc number, or if the music number designation key is pressed without any numerical key data being input. A disc playback device that can play multiple discs by identifying the first disc or a specific disc when the disc is played. with a remote control device,
This is possible through easy-to-understand operations, and enables the sharing of equipment.
