Here, it is assumed that no CD is stored in the fifth row.

In step g13, when the insertion / ejection position SW91 is turned on, it is detected that the gantry 16 has reached the insertion / ejection position, and the stair motor 31 and the insertion / ejection motor 130 are temporarily stopped. Similarly, in step g14, it is determined whether or not CD14 is held in the second-stage stocker. In step g15, it is determined whether or not CD14 is held in the first-stage stocker. The operation ends at step g16.

FIGS. 48 and 49 show the CD detection operation in step a14 of FIG. 35 as a flowchart and a time chart, respectively. The operation is started from step h1, and in step h2, the stocker motor 32 is reversed to lower the stocker 13. In step h3, when it is detected from the output of the stocker position sensor 114 that the stocker 13 has been lowered to the predetermined position, the stocker motor 32 stops. In step h4, after the elapse of the predetermined time t1, the insertion / ejection motor 130 is rotated forward, and the CD 14 mounted on the PU unit 15 is returned to the stocker 13. When the clamp position SW 203 is turned on in step h5, the insertion / ejection motor 130 is stopped. In step h6, the stocker motor 32 is rotated forward after the elapse of the predetermined time t1, and the clamp releasing operation for removing the CD 14 from the center shaft 191 is performed. When it is determined in step h7 that the stocker 13 has risen to the upper limit position from the output of the stocker position sensor 114, the stocker motor 32 is stopped. In step h8, after the elapse of the predetermined time t1, the insertion / ejection motor 130 is rotated reversely, and the PU unit 15 is retracted from the stocker 13 to perform unit ejection. When the unit origin SW 206 is turned on in step h9, the insertion / ejection motor 130 is stopped. In step h10, the stocker motor 32 is rotated reversely after the elapse of the predetermined time t1, the stocker 13 is lowered as a whole, and the stocker origin is returned. If it is determined in step h11 that the stocker 13 has dropped to the origin position from the output of the stocker position sensor 114, the stair motor 31 is rotated after a lapse of a predetermined time t1 in step h12. 16 is stopped at a predetermined position.

In step h14, after a lapse of a certain time t1, the stocker motor 32 is rotated forward, and the stocker 13 is divided and raised. At step h15, it is detected from the output of the stocker position sensor 114 that the divided upper half of the stocker 13 rises to the upper limit position.

In step h16, the insertion / ejection motor 130 is rotated forward to allow the PU unit 15 to enter the stocker 13. When the clamp position SW 203 is turned on in step h17, the insertion / ejection motor 130 is stopped. In step h18, the stocker motor 32 is rotated reversely after the elapse of the predetermined time t1, and when it is determined in step h19 that the output from the stocker position sensor 114 has dropped to the pressed position, the stocker motor 32 is stopped. In step h20, after a certain time t2 has elapsed, the stocker motor 32 is rotated forward, and the upper half of the divided stocker 13 is raised again. This rising position is determined from the output of the stocker position sensor 114 in step h21. In step h22, the insertion / ejection motor 130 is rotated reversely after the elapse of the predetermined time t1, and the CD 14 transferred to the PU unit 15 is pulled out from the stocker 13 with the retreat of the PU unit 15. When it is determined that the PU unit 15 reaches the PLAY position based on the output from the PLAY position sensor 204, the insertion / ejection motor 130 is stopped in step h23. Next, at step h24, after a lapse of a predetermined time t1, the stocker motor 32 is rotated forward to further raise the stocker 13. If it is determined in step h25 that the ascending position of the stocker 13 has reached the upper-limit stocker retreat position, the operation ends in step h26.

In the above operations, the fixed time t1 is, for example, 100 msec, and t2 is 500 msec. In the embodiment described above, since the stocker member 100 of the stocker 13 and the uppermost stocker member 101 of the first stage have a shape near the front side substantially equal to the CD 14, the upper roller 25 and the lower roller 26 Is shifted and the tip of the inserted CD 14 is directed upward, but can be guided smoothly. If the number of rollers of the transport roller 24 is increased so that the CD 14 can be inserted substantially horizontally, the front part of the stocker member 100 and the uppermost stocker member 101 can be omitted. Further, as the disc-shaped record carrier, similarly to the CD 14, it can be applied to a CD-ROM of a personal computer or the like, as well as a laser disc (CD) or a mini disc (MD). Can be applied to
