The ascending position is determined by the stocker position sensor 114 in step h21.
Judge from the output of In step h22, a fixed time t
After one elapse, the insertion / ejection motor 130 is rotated reversely, and the PU unit
15 with the retraction of the PU unit 15
Pull out from stocker 13 at first. PU unit 15 is P
The PLAY is determined by the output from the LAY position sensor 204.
When it is determined to reach the position, in step h23
The insertion / ejection motor 130 is stopped. Next, at step h24,
After the lapse of the fixed time t1, the stocker motor 32 is rotated forward and
The stocker 13 is further raised. Strike at step h25
The raising position of the stacker 13 reaches the upper limit stocker retreat position.
If so, the operation is ended in step h26. In each of the above operations, the predetermined time t1 is, for example,
100 msec and t2 is 500 msec.
In the embodiment described above, the stocker unit of the stocker 13
The material 100 and the first uppermost stocker member 101 are
The portion closer to the front has almost the same shape as CD14.
Therefore, the positions of the upper roller 25 and the lower roller 26 are shifted.
The tip of the inserted CD14 faces upward
And can be guided smoothly. B of the transport roller 24
The insertion of CD14 is almost horizontal by increasing the number of
So that the stocker member 100 and the uppermost
Do not provide the front part of the stocker member 101
You can also. The number of stages is not limited to six, of course.
It is. As a disc-shaped record carrier, same as CD14
The same applies to CD-ROMs such as personal computers.
Of course, it can be applied to
(CD) and mini disc (MD)
can do. As described above, according to the present invention, the conveying means
Is at least between the vicinity of the insertion port and the position away from the insertion port.
Recording media inserted from the insertion slot
The body can be efficiently stored in the storage means and regenerated by the
Can be. Also, insert a disc-shaped note
Guide the recording media smoothly while the leading edge of the recording media faces upward
be able to. The following is an explanation of the operation.
