Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an autochanger device for reproducing audio signals and the like, and more particularly to a device for switching between a reproduction signal by an optical disc player and a reproduction signal by a reproducing means.

[Prior Art] Conventionally, for example, an optical disc player for reproducing an optical disc (digital audio disc) in which audio signals converted into a digital amount are recorded as innumerable pits is generally known. There is. This optical disc player has been rapidly popularized because it is easier to handle a disc to be reproduced than a so-called normal analog disc (record), is easy to operate, and produces a reproduced sound with excellent sound quality. It's starting. In recent years, in particular, as a so-called karaoke device, an increasing number of restaurants have installed an optical disk player in the store instead of a tape recorder.

[Problems to be solved by the invention]

By the way, a desired song (plurality) is not always recorded in one disc, and when it is not recorded, the disc must be replaced, which is troublesome. A so-called auto-changer system is known as a means for eliminating this trouble. This automatic chain system has a disk storage portion in which a plurality of disks are stored, and when the reproduction of the music is completed, the disk is automatically returned to a predetermined position in the disk storage portion, and is designated next. It has a function of taking out a disk (in which desired music is recorded) from the disk storage portion and setting it in the disk player. Especially, as described above, a disk player for karaoke is installed in the store. It is a very convenient system in all cases.

However, when a disc is exchanged using such an auto-changing system, it takes about 10 seconds on average from the end of the previous song to the start of the next song. Moreover, during this access period, there was no sound and the feeling of frustration was undeniable.

There is also known a car audio system, that is, a so-called car stereo, which has a function of automatically outputting a radio sound during a rewinding operation of a cassette tape in a silent state. However, in this case, since the listening is started in the middle of a series of broadcast programs, and the reproduction of the next song is started in the middle of the broadcast programs, the discomfort is undeniable.

Therefore, the present invention has been proposed in view of the above-mentioned conventional problems, and after the end of a song, the optical disc is exchanged using the autochanger system to start playing the next song (desired song). It is an object of the present invention to provide an autochanger device capable of softening a feeling of frustration that occurs during a silent access period until the start of operation.

[Means for solving problems]

In order to achieve the above-mentioned object, an autochanger device according to the present invention mounts a disc storage unit for storing a plurality of optical discs and an optical disc selected from the disc storage units on an optical disc player. A mechanism section having both a mechanism and a mechanism for returning the mounted optical disc to a predetermined position in the disc storage section, an optical disc player for reproducing the mounted optical disc, and a predetermined signal recorded. Playing means for playing
Switching means for selecting a reproduction signal by the optical disc player and a reproduction signal by the reproducing means, control means for controlling the mechanical section, the optical disc player, the reproducing means and the switching means, and the optical means. And a music interval detecting means for generating a music interval detecting signal using a time code signal pre-recorded on the optical disk, and the optical disk when the end of the music is detected based on the music interval detecting signal. The control is such that the reproduction signal from the player is switched to the reproduction signal from the reproduction means, the reproduction signal from the reproduction means is output for at least a predetermined time, and then the reproduction signal from the reproduction means is switched to the reproduction signal from the optical disc player. I am trying.

[Action]

According to the present invention, the time code signal pre-recorded in the optical disc player is used to detect the interval between songs, so that at the end of the song in the reproduction signal from the optical disc player, a reproducing means such as a ROM is provided. A reproduction signal such as a clap sound from is reproduced for a predetermined time or longer.

〔Example〕

Hereinafter, an embodiment of an autochanger device according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of the autochanger device of this embodiment. In FIG. 1, an internal audio signal (tone signal) of a signal reproduced by an optical disk player 1 (hereinafter, simply referred to as a disk player) which is a first reproducing means is a selected terminal 11 of a switch 10. , And the time code signal is supplied to the microcomputer 2. The time code signal is, for example, a (+) sign during the performance of a song (during a song) and a (-) sign between songs. Based on the supplied time code signal, each control signal is output from the microcomputer 2 to control the disk player 1 and the address counter 3 and the switching of the switch 10. Audio data, in this embodiment, clapping sound data is written in a ROM (Read Only Memory) 4, and the data sequentially read from the ROM 4 according to the address signal from the address counter 3 is D A continuous clap sound signal sent to the / A (digital / analog) conversion circuit 5 is supplied to the selected terminal 12 of the switch 10. The address counter 3, the ROM 4, and the D / A conversion circuit 5 constitute second reproducing means. In addition, the switch
The selection terminal 13 of 10 is connected to the output terminal 6, and the audio signal (tone signal) from the disk player 1 or the ROM 4
One of the clap-sound signals according to is output from the output terminal 6. The output terminal 6
Is connected to the speaker system via, for example, an amplifier.

Although not shown, the above-mentioned microcomputer 2
A music title designating button for designating a music piece, an automatic changer system for converting a disc, and the like are also connected to.

Next, an example of the operation of the thus-configured autochanger device of this embodiment will be described with reference to the flowchart of FIG.

First, when the singer's desired song (karaoke) is designated, the disc in which the song is recorded is set to the disc player 1 by the above-mentioned auto-chaining system, and the performance of the first song is started. (Step). The selection terminal 13 of the switch 10 is connected to the selected terminal 11 side as shown in FIG.

Next, the microcomputer 2 determines whether or not the performance of the first tune has ended (step). this is,
This is performed by discriminating the code of the time code signal supplied from the disk player 1. And
This step is repeated until the performance of the first piece of music is completed, and when the performance is completed, the process proceeds to the next step.

Here, the selection terminal 13 of the switch 10 is switched and connected to the selected terminal 12 side, and the clap sound data is output from the ROM 4 in accordance with the address signal from the address counter 3, and this data is output to the D / A conversion circuit. It is converted into an analog quantity by 5 and supplied to the selected terminal 12. As a result, the reproduction of the clap sound is started (step).

Then, the time counting operation (timer operation) by the microcomputer 2 is started (step). This timing operation is an operation for measuring a predetermined time t ₀ , as will be described later, and determines the shortest reproduction time of the clap sound.

Next, the microcomputer 2 determines whether or not the next music piece is designated (step). It is assumed that the tune is designated by the above-mentioned tune designation button (not shown) during the performance of the first tune or before the start of the performance.

When the designation is made, the access to the designated song is started. That is, the disc is exchanged by the above-mentioned auto-changing system (not shown), the disc containing the designated song is set in the disc player 1, and the optical pickup device of the disc player 1 is moved to the head position of the designated song. When moved, a series of operations is started (step). When the designated song (next song) is recorded on the same disc as the first song, the disc is not exchanged and the optical pick-up device of the disc player 1 is only moved.

Next, the microcomputer 2 determines whether or not the access to the designated music has been completed (step). Then, this step is repeated until the access is completed, and when the access is completed, the process proceeds to the next step.

Next, it is judged whether or not a predetermined time t ₀ has elapsed from the time (step) when the time counting operation by the microcomputer 2 is started (step). This predetermined time t ₀ is
For example, it may be set to an appropriate time between the shortest time and the longest time required to access the designated music.
Then, when the access is completed in a short time (<t ₀₎ until the predetermined time t ₀ has elapsed repeat this step, the process proceeds when the predetermined time t ₀ has elapsed the next step. If the access requires a long time (> t ₀ ), the process immediately proceeds to the next step.

At this time, the data output from the ROM 4 is stopped and the selection terminal 13 of the switch 10 is switched and connected to the selected terminal 11 side. As a result, the clapping sound being played is stopped (step).

Then, after the resetting of the timing operation by the microcomputer 2 is performed (step), the process returns to step again and the disc player 1 starts playing the second tune.

On the other hand, if the next tune is not designated at the step, the designated tune is not accessed and, like the step, a predetermined time t from the time (step) when the time counting operation by the microcomputer 1 is started. _It is determined whether or not ₀ has elapsed (step). Then, until the predetermined time t ₀ has elapsed repeat this step, the process proceeds to the next step when the predetermined time t ₀ has elapsed.

Here, an operation similar to that of step is performed, and the clapping sound being reproduced is stopped (step).

And, like the step, the micro computer 2
The resetting of the timing operation is performed (step), and the series of operations is completed. At this point in time, the autochanger device of the present embodiment is in a standby state (standby state), for example.

As described above, in the automatic changer device of this embodiment, when the next song is designated, the clapping sound is reproduced during the period from the end of the song to the start of the next song. . The reproduction time of the clap sound changes according to the time required for access (access time), but when the access time is shorter than the predetermined time t ₀ , the time t _{0 is} fixed. That is, the shortest reproduction time of the clap sound is the predetermined time t ₀ . Therefore, even if the access ends in an extremely short time, the performance of the next song does not start immediately, and the performance of the next song starts after the clapping sound is reproduced for a predetermined time t _0. . Therefore, it has the effect of helping to raise the atmosphere of the place. Even when it takes a long time to access, the applause sound is played until the start of the next song, so that the feeling of frustration can be eased and the atmosphere on the spot can be enhanced. on the other hand,
When the next song is not designated, the clapping sound is reproduced for a predetermined time t ₀ from the time when the song ends. Therefore, an effect such as clapping sound is maintained even after the music is finished.

Further, the autochanger device may start the operation from the step shown in FIG. By doing so, it is possible to confirm that the clap sound is reproduced even before the performance of the first song and the autochanger device is in the operating state, and at the same time, the volume and the like can be adjusted while listening to the clap sound. Further, in the case where the disc player 1 plays a piece of music other than karaoke, which can be independently listened to, the operator of the apparatus should give some time to reach the optimum listening position (listening position). You can

The present invention is not limited to the above-mentioned embodiment, and an endless tape or the like may be used as the second reproducing means. Further, the sound reproduced by the second reproducing means is not limited to the clap sound, and any sound such as a wave sound which does not cause any discomfort even if it starts and ends can be used. Furthermore, this sound may be played back by so-called fade-in or fade-out. Furthermore, a so-called video disk player or the like that reproduces a video signal and an audio signal may be used as the first reproducing means.

[Effect of device]

As is apparent from the above description of the embodiment, according to the autochanger device of the present invention, after the end of a song, the optical disc is exchanged using the autochanger system to start the performance of the next song. Since signals such as clap sounds are reproduced during the period up to, it is possible to sufficiently alleviate the feeling of frustration. In addition, it is possible to obtain effects such as being useful for raising the atmosphere of the place. Furthermore, it is possible to play back clap sounds and other signals even before the start of a song. This makes it possible to confirm that the autochanger device is operating, and adjust the volume while listening to clap sounds, etc. It is also possible to obtain the effect that the operator of the apparatus can reach the optimum listening position with a sufficient time.
