Abstract

Abstract A reproducing apparatus for a rotary recording medium accommodated within a jacket. The apparatus comprises a jacket opening enlarging mechanism which enables the jacket to move above a turntable positioned between an inserting opening through which the jacket is inserted and a rear part of the apparatus. The jacket opening enlarging mechanism comprises upper and lower enlarging members which are aligned horizontally with the inserting opening, when the jacket opening enlarging mechanism is in the vicinity, for receiving the inserted case. The upper and lower enlarging members are pivotally coupled to each other, with their front edges mutually open toward the inserting opening and their rear edges mutually closed. The respective rear edges of the upper and lower enlarging members open and mutually separate from each other as the jacket opening enlarging mechanism moves toward the rear part of the reproducing apparatus responsive to the insertion of the case.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 347 words
An apparatus for reproducing a rotary recording medium accommodated within a case, said case comprising a jacket having a space for accommodating the rotary recording medium therein and an opening through which said medium can enter and leave the jacket and a lid member inserted through said opening of the jacket for covering and closing the opening, said reproducing apparatus comprising: a front side having an elongated inserting opening therein through which the case is inserted; holding means disposed at a rear part of the reproducing apparatus, for holding the rotary recording medium within the reproducing apparatus responsive to an insertion of the case into the reproducing apparatus and then a withdrawal of the jacket from the reproducing apparatus; turntable means positioned between said inserting opening and a rear part of the reproducing opening for rotating the recording medium thus left within the reproducing apparatus; and jacket opening enlarging means for coupling with the jacket and being movable over the turntable means between the inserting opening and said rear part of the reproducing apparatus, said enlarging means coordinating with the insertion and extraction of said case having the jacket, said jacket opening enlarging means comprising upper and lower elongated enlarging members aligned horizontally with said inserting opening when said jacket opening enlarging means is prepared for receiving the inserted case, said upper and lower enlarging members being pivotally coupled to each other with their front edges being mutually open toward said inserting opening and their rear edges being mutually closed; finger means projecting toward said inserting opening on the respective front edges of said upper and lower enlarging members, said fingers entering into cutouts in the lid member and mutually separating from each other to enlarge the opening of the jacket as the case is inserted through the inserting opening and into the reproducing apparatus; and means for opening said respective rear edges of said upper and lower enlarging members to mutually separate from each other as said jacket opening enlarging means moves towards said rear part of said reproducing apparatus during the insertion of the case.
Claim 2
Independent Claim 347 words
An apparatus for reproducing a rotary recording medium accommodated within a case, said case comprising a jacket having a space for accommodating the rotary recording medium therein and an opening through which said medium can enter and leave the jacket and a lid member inserted through said opening of the jacket for covering and closing the opening, said reproducing apparatus comprising: a front side having an elongated inserting opening therein through which the case is inserted; holding means disposed at a rear part of the reproducing apparatus, for holding the rotary recording medium within the reproducing apparatus responsive to an insertion of the case into the reproducing apparatus and then a withdrawal of the jacket from the reproducing apparatus; turntable means positioned between said inserting opening and a rear part of the reproducing opening for rotating the recording medium thus left within the reproducing apparatus; and jacket opening enlarging means for coupling with the jacket and being movable over the turntable means between the inserting opening and said rear part of the reproducing apparatus, said enlarging means coordinating with the insertion and extraction of said case having the jacket, said jacket opening enlarging means comprising upper and lower elongated enlarging members aligned horizontally with said inserting opening when said jacket opening enlarging means is prepared for receiving the inserted case, said upper and lower enlarging members being pivotally coupled to each other with their front edges being mutually open toward said inserting opening and their rear edges being mutually closed; finger means projecting toward said inserting opening on the respective front edges of said upper and lower enlarging members, said fingers entering into cutouts in the lid member and mutually separating from each other to enlarge the opening of the jacket as the case is inserted through the inserting opening and into the reproducing apparatus; and means for opening said respective rear edges of said upper and lower enlarging members to mutually separate from each other as said jacket opening enlarging means moves towards said rear part of said reproducing apparatus during the insertion of the case.
Claim 3
Dependent Claim 65 words
A reproducing apparatus as claimed in claim 1 in which the jacket has windows formed in upper and lower surfaces thereof in the vicinity of said opening of the jacket, and at least one of the upper and lower enlarging members has lugs for engaging and fitting into the windows of the jacket having the enlarged opening, said lugs being provided independently of said fingers.
Claim 4
Dependent Claim 28 words
A reproducing apparatus as claimed in claim 2 in which the fingers have a length (l) such that free ends of the fingers do not reach the lugs.
Claim 5
Dependent Claim 20 words
A reproducing apparatus as claimed in claim 2 in which the lugs are provided on only the upper enlarging member.
Claim 6
Dependent Claim 24 words
A reproducing apparatus as claimed in claim 2 in which each lug is formed with an arcuate part which extends toward the inserting opening.
Claim 7
Dependent Claim 25 words
A reproducing apparatus as claimed in claim 2 in which each lug is formed with an angular part which extends away from the inserting opening.
Claim 8
Dependent Claim 61 words
A reproducing apparatus as claimed in claim 1 in which the means for opening said respective rear edges comprises a tapered part formed in a guide rail for guiding the enlarging means at an end of the guide rail toward the inserting opening, and rollers on the upper and lower enlarging members for rolling over tapered surfaces of the tapered part.
