Abstract

A reproducing apparatus for a disc-like recording medium in which administration information of recorded information is recorded together with the information has a stocking section, a reproducing section, a transferring mechanism, a memory and a controller. A plurality of disc-like recording media are stocked in the stocking section in a laminate fashion. The reproducing section reproduces the information and the administration information recorded in the disc-like recording medium. The transferring mechanism selectively picks up the disc-like medium from the stocking section and transfers the picked-up recording medium between the stocking section and the reproducing section and transfers the recording medium to an eject position from the reproducing apparatus. The memory stores the administration information of the recording medium read out or reproduced by the reproducing section and information concerning a reproduction order. The controller controls each operation of the transferring mechanism, the reproducing section and the memory. When the recording medium is transferred to the eject position by the transferring mechanism, the controller deletes the information of administration of the recording medium transferred to the eject position and the reproduction order stored in the memory.

Claims

1. A control method for a reproducing apparatus for a recording medium, said apparatus having a stocking section for stocking a plurality of recording media, reproducing means for reproducing information from the recording medium, transferring means for selectively picking up the recording medium from said stocking section, transferring the recording medium between said stocking section and said reproducing means, and transferring the recording medium to an eject position through an opening portion of said reproducing apparatus and position detecting means for detecting positions of said transferring means, said method comprising the step of:

under a condition before execution of a normal operation including a reproduction start of the recording media by said reproducing means, after said position detecting means detects that said transferring means has reached an initial position, performing a returning operation of the recording medium into said stocking section by said transferring means, thereby recognizing an operational condition of said transferring means.

2. The method according to claim 1, wherein when a returning operation of the recording medium to said stocking section by said transferring means is impossible, said transferring means is moved to a stocking position in which other recording medium of the plurality of recording media are stocked in said stocking section, thereby performing the returning operation.

3. The method according to claim 2, wherein when the returning operation of the recording medium to said stocking section by said transferring means is impossible in a position of any of said recording medium, the recording medium is moved to the eject position by said transferring means, and thereafter said transferring means is again moved to the stocking position, thereby performing the returning operation.

4. The method according to claim 1, wherein when closing means for closing the opening portion of said reproducing apparatus is opened, the transferring operation of said transferring means is stopped.

5. The method according to claim 4, wherein when said closing means for closing the opening portion of said reproducing apparatus is again closed after the transferring operation of said transferring means has been stopped, said transferring operation of said transferring means is re-started.

6. A control method for a reproducing apparatus for a recording medium, said apparatus having a stocking section for stocking a plurality of recording media, reproducing means for reproducing information from the recording media, transferring means for selectively picking up the recording medium from said stocking section and transferring the recording medium between said stocking section and said reproducing means, and transferring the recording medium to an eject position through an opening portion of said reproducing apparatus and opening/closing means for moving in an opening direction to enable said transferring to move to the eject position, said method comprising the step:

when said transferring means is kept under a transferring condition and when said opening/closing means is moved in the opening direction, stopping the transferring operation of said transferring means.

7. The method according to claim 6, wherein when said opening/closing means is moved in a closing direction, the transferring operation is re-started from the stopped condition of said transferring means.

8. The method according to claim 6, wherein when said opening/closing means is opened under the condition that said transferring means is moved between said stocking section and said reproducing means, the operation of said transferring means is interrupted and stopped.

9. A reproducing apparatus for a recording medium, comprising:

a stocking section for stocking a plurality of recording media;

reproducing means for reproducing information recorded in the recording medium;

transferring means for selectively picking up the recording media from said stocking section and transferring the recording medium between said stocking section and said reproducing means, and transferring the recording medium to an eject position out of said reproducing apparatus;

position detecting means for detecting positions of said transferring means; and

control means for controlling each operation of said transferring means and said reproducing means, wherein under a condition before execution of a normal operation including a reproduction start by said reproducing means, after said position detecting means detects that said transferring means has reached an initial position, said control means performs a returning operation of the recording medium into said stocking section by said transferring means.

10. The apparatus according to claim 9, said apparatus further comprises detecting means for detecting whether or not a power source supply is connected to said reproducing apparatus, wherein said control means performs the returning operation on the basis of a signal from said detecting means.

11. The apparatus according to claim 10, wherein said position detecting means comprises a first position detecting means for detecting a position of said transferring means relative to said stocking section and a second position detecting means for detecting that said transferring has reached the initial position, wherein said control means performs the returning operation of said transferring means on the basis of output signals from said first and second position detecting means.

12. The apparatus according to claim 11, said apparatus further comprises an opening portion for enabling said transferring means to transfer up to the eject position and opening/closing means for opening/closing said opening portion, wherein when said opening/closing means is moved to a position for opening said opening portion, said control means stops the transferring operation of said transferring means.

13. The apparatus according to claim 12, wherein said apparatus further comprises opening/closing detecting means for detecting whether said opening/closing means is moved to a position for opening said opening portion, wherein said control means stops the transferring operation of said transferring means on the basis of a detection signal from said opening/closing means.
