Abstract A reproducing apparatus reproduces a disc-shaped recording medium which is accommodated within a case comprising a jacket which has a space for accommodating the disc-shaped recording medium and an opening for allowing the disc-shaped recording medium to go in and out of the jacket, and a lid member inserted through the opening of the jacket for closing the opening of the jacket, where the lid member has cutouts and ride-over parts. The reproducing apparatus comprises an inserting opening through which the case is inserted, a turntable for rotating the disc-shaped recording medium, a clamping mechanism for clamping at least one of the disc-shaped recording medium and the lid member provided at an innermost part on the opposite side from the inserting opening with respect to the turntable, a detecting mechanism for detecting whether the disc-shaped recording medium is loaded within the reproducing apparatus, a reproducing transducer for reproducing the disc-shaped recording medium placed on the turntable, a reproducing operation mechanism for moving the reproducing transducer from a waiting position to a reproducing position with respect to the disc-shaped recording medium to perform a reproducing operation, and an operating mechanism connected to the detecting mechanism and the reproducing operation mechanism and operated upon starting of the reproducing operation, for operating the reproducing operation mechanism only when operated in a state where the detecting mechanism is detecting whether a disc-shaped recording medium is loaded within the reproducing apparatus.
A reproducing apparatus for reproducing a disc-shaped recording medium which is accommodated within a case, said case comprising a jacket which has a space for accommodating said disc-shaped recording medium and an opening for allowing said disc-shaped recording medium to go in and out of said jacket, and a lid member inserted through said opening of said jacket for closing said opening of said jacket, said lid member having cutouts and ride-over parts, said reproducing apparatus comprising: an inserting opening through which said case is inserted; a turntable for rotating said disc-shaped recording medium; clamping means for clamping at least one of said disc-shaped recording medium and said lid member provided at an innermost part on the opposite side from said inserting opening with respect to said turntable; detecting means for detecting whether said disc-shaped recording medium is loaded within said reproducing apparatus; a reproducing transducer for reproducing the disc-shaped recording medium placed on said turntable; reproducing operation means for moving said reproducing transducer from a waiting position to a reproducing position with respect to the disc-shaped recording medium to perform a reproducing operation; and operating means connected to said detecting means and said reproducing operation means and operated upon starting of the reproducing operation, for operating said reproducing operation means only when operated in a state where said detecting means is detecting whether a disc-shaped recording medium is loaded within said reproducing apparatus.

A reproducing apparatus for reproducing a disc-shaped recording medium which is accommodated within a case, said case comprising a jacket which has a space for accommodating said disc-shaped recording medium and an opening for allowing said disc-shaped recording medium to go in and out of said jacket, and a lid member inserted through said opening of said jacket for closing said opening of said jacket, said lid member having cutouts and ride-over parts, said reproducing apparatus comprising: an inserting opening through which said case is inserted; a turntable for rotating said disc-shaped recording medium; clamping means for clamping at least one of said disc-shaped recording medium and said lid member provided at an innermost part on the opposite side from said inserting opening with respect to said turntable; detecting means for detecting whether said disc-shaped recording medium is loaded within said reproducing apparatus; a reproducing transducer for reproducing the disc-shaped recording medium placed on said turntable; reproducing operation means for moving said reproducing transducer from a waiting position to a reproducing position with respect to the disc-shaped recording medium to perform a reproducing operation; and operating means connected to said detecting means and said reproducing operation means and operated upon starting of the reproducing operation, for operating said reproducing operation means only when operated in a state where said detecting means is detecting whether a disc-shaped recording medium is loaded within said reproducing apparatus.
Claim 3
Dependent Claim
77 words
A reproducing apparatus as claimed in claim 1 in which said detecting means is a detecting switch which detects the side of the loaded disc-shaped recording medium which is to be reproduced, and said operating means has an operation switch connected in series with said detecting switch with respect to a power source and circuit means for close-circuiting said reproducing operation means to said power source when both said detecting switch and said operation switch are closed.
Claim 4
Dependent Claim
50 words
A reproducing apparatus as claimed in claim 2 in which said reproducing operation means comprises a motor for moving said reproducing transducer, and said circuit means comprises a transistor connected in series with said motor with respect to said power source and having the base connected to said operation switch.
Claim 5
Dependent Claim
168 words
A reproducing apparatus as claimed in claim 1 in which: said lid member is provided with a cutout on the front surface at a position deviated from the central part thereof; said detecting means has a first detecting switch which enters within the cutout of said lid member upon loading of said disc-shaped recording medium with one side as the side which is to be reproduced, and a second detecting switch which enters within the cutout of said lid member upon loading of said disc-shaped recording medium with the other side as the side which is to be reproduced, said first and second detecting switches being connected in parallel with respect to said power source; and said operating means has an operation switch connected in series with the parallel connection detecting switches with respect to said power source, and circuit means for close-circuiting said reproducing operation means to said power source when both said operation switch and either one of the first and second detection switches are closed.
Claim 6
Dependent Claim
31 words
A reproducing apparatus as claimed in claim 1 in which said detecting means further comprises first and second display means respectively connected in series with said first and second detecting switches.
