After both the first and second detection levers 129 and 128 move toward the outer side of the disc stocker 62, only the first detection lever 129 moves toward the inner side of the disc stocker 62. When the disk stockers 62 and
Is determined to have been inserted in the normal direction.

Therefore, the microcomputer, as shown in FIGS. 101 to 103, when the disk cartridges 320 and 321 are erroneously inserted with the front and back reversed, as shown in FIGS. 104 to 107. The erroneous insertion is detected, and the disc cartridges 320 and 321 are ejected from the disc stocker 62. This discharge is performed by the front transport device.

When such an erroneous insertion is made, the outputs V _C1 , V from the push switches 116, 117 are output.
_{Both C2} remain at the "H" level as shown in FIG.

In the microcomputer 112, both outputs V _C1 and V _C2 have become "H" level (FIG. 134).
In the middle section “C”), that is, after the first and second detection levers 129 and 128 are both moved toward the outer side of the disk stocker 62, several seconds (for example, about 5 seconds). If the first output V _C1 does not _fall to the “L” level within this time, it is determined that the insertion is incorrect.

The microcomputer shown in FIG.
As shown in FIGS. 08 to 111, when the disc cartridges 320 and 321 are erroneously inserted by being turned over, the erroneous insertion is detected as shown in FIGS. 112 to 115, and the disc cartridges are detected. 32
0, 321 is ejected from the disc stocker 62.

When such an erroneous insertion is made, the outputs V _C1 , V from the push switches 116, 117 are output.
_As shown in FIG. 135, _C2 remains at the "H" level.

In the microcomputer 112, both outputs V _C1 and V _C2 have become "H" level (FIG. 135).
In the middle section “C”), that is, after the first and second detection levers 129 and 128 are both moved toward the outer side of the disk stocker 62, several seconds (for example, about 5 seconds). If the first output V _C1 does not _fall to the “L” level within this time, it is determined that the insertion is incorrect.

[0240] Here, the second detection lever 12
8 is capable of independently rotating without following the first detection lever 129, the outputs V _C1 and V _C2 from the pressure switches 116 and 117 are as shown in FIG.
As shown at 36, after both have become "H" level, only the second output V _C2 becomes "L" level.

In this case as well, the microcomputer 112, when both the outputs V _C1 and V _C2 are at the “H” level, that is, the first and second detection levers 1
With the fact that the first output V _C1 does not become the “L” level within a few seconds (for example, about 5 seconds) after both 29 and 128 are moved toward the outside of the disk stocker 62, Determined as an incorrect insertion.

The microcomputer shown in FIG.

When such an erroneous insertion is made, the outputs V _C1 , V from the push switches 116, 117 are output.
_As shown in FIG. 137, _C2 becomes both "H" level and "L" level. This is because the disc cartridges 320 and 321 have a lateral width longer than the front-rear length, and therefore, when inserted laterally, the disc cartridges 62 play back and forth in the disc stocker 62 and move irregularly from side to side.

When the outputs V _C1 and V _C2 are both at the "H" level, that is, when the first and second detection levers 129 and 128 are both outside the disk stocker 62, Only the first output V _C1 does not become “L” level within a few seconds (for example, about 5 seconds) after being moved to the side (the second output V _C2 is “H” level). Is not maintained in), it is determined to be an incorrect insertion.

The disk stocker 62 as described above is used.
As shown in FIGS. 185 and 186, erroneous insertion prevention members 237 and 240 that are movably supported and that can move forward and backward with respect to the disk stocker 62 are prevented.
It is possible to do by.

However, in this case, when the disc stocker 62 is moved up and down by the elevating device, the misinsertion preventing members 237 and 240 must be retracted from the disc stocker 62, which makes the control complicated. In addition, since the movable erroneous insertion preventing member has low mechanical strength, erroneous insertion may not be reliably prevented. (8-3) Continuous recording and continuous reproduction (FIGS. 189 to 19)
8) As shown in FIGS. 189 to 193, the microcomputer 112 that controls the lifting device and each of the transport devices operates when the recording of the information signal to the first disk cartridge 320a in the base unit 114 is completed. The first disc cartridge 320a is conveyed into the disc stocker 62 by the rear side conveying device, and then the first disc cartridge 320a is moved by the elevating device to a position where the side surface portion faces the front side conveying device. Further, the first disc cartridge 320a is ejected to the front side of the disc stocker 62 by the front transport device, and at this time, the second disc cartridge 320b whose side surface is opposed to the rear transport device. Is conveyed by this rear side conveying device and the base unit It is attached to the knit 114.

That is, this disc changer device is constructed so as to convert an audio signal into a digital signal and write it on the recording disk. After the digital signal converted from the audio signal is subjected to signal compression processing. ,
It is configured to write to the recording disc.

That is, in this disc changer device, the time required for writing the compressed signal on the recording disc is shorter than the time for recording the audio signal. Further, at the time of reproduction, the time required for reading the compressed signal from the recording disk is shorter than the time for the reproduced audio signal.

Therefore, in this disc changer device, at the time of recording, the signal sequentially digitally converted from the audio signal is temporarily stored in the memory 113,
Signals are sequentially read from the memory 113 and signal compression processing is performed. Further, at the time of reproduction, the compressed signal is intermittently read from the recording disk, subjected to the expansion processing, temporarily stored in the memory 113, and the signal is sequentially read from the memory 113 to perform analog conversion.

Therefore, in this disc changer device, the writing of a signal to the recording disc is performed as follows.
While continuing to input signals to the memory 113,
It can be interrupted only for a time corresponding to the capacity of the memory 113.

Further, in this disc changer device, even if the reading of the signal from the recording disc is interrupted for a time corresponding to the capacity of the memory 113, the signal output from the semiconductor memory can be continued. .

That is, in this disc changer device, when the signal is written to the first disc cartridge and the writing up to the limit of the recording capacity of the first disc cartridge is completed, the first disc cartridge Is immediately replaced with the second disk cartridge and the signal writing to the second disk cartridge is started, so that continuous recording can be performed.

Similarly, in this disc changer device, continuous reproduction can be performed over a plurality of disc cartridges.

The memory 113 is provided for the first disc while the writing or reading of the signal to the recording disc is interrupted, that is, from the end of the writing (reading) of the signal to the first disc cartridge 320a. The cartridge 320a is attached to the base unit 114
From the second disk cartridge 320b.
Has a capacity enough to store an audio signal until it is mounted on the base unit 114 and the writing (reading) of the signal is started.

In this disc changer device,
As shown in FIG. 189, the disc stocker 62 holds a plurality of disc cartridges in a stacked state. First, as shown in FIG. 190, the first disc cartridge 320 a is carried into the disc holder 118 and is positioned on the base unit 114. Then, this first disk cartridge 320a
As shown in FIG. 191, the base unit 114
It is mounted on and the signal is recorded.

Then, the first disk cartridge 320a is returned to the disk stocker 62, as shown in FIG. Next, the disc stocker 62
However, as shown in FIG. 192, it is moved upward by one step.

At this time, as shown in FIG. 193, the first disc cartridge 320a can be ejected to the front side of the disc stocker 62, and the second disc cartridge 320b can be ejected to the rear side of the disc stocker 62. The disc holder 118 can be transported to and mounted on the base unit 114.

In this disc player device, the height position of the disc cartridge which is operated from the outside to the disc stocker 62 and the disc cartridge which is transported from the disc stocker 62 to the disc holder 118 side. These two operations can be performed on different disk cartridges at the same time because the height position of the disk is different.

The recorded disk cartridge needs to be taken out of the disk changer device immediately after the recording is completed when it is necessary to check the recording state by another device or reproduce the recorded signal. In this disc changer device, as described above, the recorded disc cartridge can be taken out of the disc changer device immediately after the recording is completed, and the information signal can be continuously recorded on the other disc cartridges. be able to.

It should be noted that, as shown in FIGS. 194 to 198, the height position of the disc cartridge that is operated to enter and exit from the disc stocker 62 from the outside, and the height position of the disc cartridge from the disc stocker 62 to the base unit 114 side. If the height position of the operated disk cartridge is the same, these two operations cannot be performed simultaneously on different disk cartridges.

That is, in this case, as described above,
Immediately after the recording of the signal on the first disc cartridge 320a is completed, the second disc cartridge 3
When the 20b is mounted in the recording / reproducing section, the first disc cartridge 320a, which has been recorded, can be taken out from the disc stocker 62 to the outside by using FIG.
As shown in FIG. 7, the disk stocker 62 has to be moved again. That is, in this case, since it takes time to move the disc stocker 62 after mounting the second disc cartridge 320b on the recording / reproducing unit, the recorded first disc cartridge 320a is immediately taken out. I can't.

In this case, as shown in FIG. 198, immediately after the recorded first disc cartridge 320a is returned to the disc stocker 62, the first disc cartridge 320a is recorded.
If the first disk cartridge 320a is not completely taken out from the disk stocker 62, the second disk cartridge 3a is taken out from the disk stocker 62.
20b cannot be attached to the recording / playback unit. At this time, if the disc cartridge is removed from the disc stocker 62 by a manual operation, continuous recording cannot be performed unless the removal operation is surely performed promptly.

The present invention is not limited to the disc changer device configured to accommodate a plurality of disc cartridges at the same time as described above, and only one recording disc is mounted and information for this recording disc is recorded. The present invention can also be applied to a disc player device that records or reproduces signals.

[0264]

As described above, in the disc loading apparatus according to the present invention, the discriminating means is the first detecting member which is fitted into the carrying recess formed in the side surface portion of the disc cartridge inserted into the disc stocker. And a second detection member that comes into contact with a side surface portion of the disc cartridge that is deviated from the movement trajectory of the transport recess when the disc cartridge is inserted into the disc stocker. Then, when only the first detection member moves toward the inner side of the disc stocker after moving toward, the disc cartridge is determined to be inserted in the proper direction with respect to the disc stocker.

Therefore, the discriminating means can surely detect the erroneous insertion regardless of the force of inserting the disc cartridge into the disc stocker.

In this disc loading device, when the disc cartridge is inserted in the proper direction with respect to the disc stocker and the first detecting member is fitted into the carrying recess, the disc cartridge is inserted into the disc stocker. When the stopper member for preventing the movement in the direction is provided, the disc cartridge can be stopped at the timing of detecting the erroneous insertion, so that the erroneous insertion can be detected more reliably.

That is, the present invention can provide a disc loading device capable of surely preventing the erroneous insertion of the disc cartridge into the disc stocker.
