摘要： A reproducing apparatus reproduces a disc-shaped recording medium which is accommodated within a case comprising 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 plate inserted through the opening of the jacket for closing the opening of the jacket. The reproducing apparatus comprises an inserting opening through which the case is inserted a lid plate locking mechanism and disc-shaped recording medium clamping mechanism respectively provided at the innermost part of the reproducing apparatus opposite to the inserting opening with respect to a turntable, for rotating the disc-shaped recording medium, and a jacket opening enlarging mechanism provided in the vicinity of the inserting opening, capable of moving over the turntable between the position in the vicinity of the inserting opening and the innermost part of the reproducing apparatus. The jacket opening enlarging mechanism has an enlarging member for enlarging the opening of the jacket by entering inside the cutouts of the lid plate, upon insertion of the jacket into the reproducing apparatus through the inserting opening. The lid plate locking mechanism has a locking member for locking the lid plate by entering inside the cutouts of the lid plate, upon insertion of the lid plate into the innermost part of the reproducing apparatus together with the jacket. The disc-shaped recording medium clamping mechanism has a clamping member for clamping the disc-shaped recording medium within the jacket by riding over the ride-over part of the lid plate and entering through the enlarged opening of the jacket, upon insertion of the lid plate into the innermost part of the reproducing apparatus together with the jacket.
摘要翻译：再现装置再现一种盘形记录介质，其容纳在具有用于容纳盘形记录介质的空间的外壳的壳体和用于允许盘形记录介质进出外壳的开口，以及通过所述护套的开口插入以封闭所述护套的开口的盖板。再现装置包括插入开口，壳体通过其插入盖板锁定机构和分别设置在再现装置的与插入口相对的转盘的最内部的盘形记录介质夹持机构，用于使盘形记录介质和设置在插入孔附近的护套开口扩大机构，能够在转盘附近在插入口附近的位置和再现装置的最内部之间移动。护套开口扩大机构具有扩大构件，用于通过插入口将护套插入到再现装置中，通过进入盖板的切口内而扩大护套的开口。盖板锁定机构具有锁定构件，用于在将盖板与护套一起插入到再现装置的最内部部分中时，通过进入盖板的切口来锁定盖板。盘形记录介质夹紧机构具有夹紧构件，用于通过在盖板的越过部分上方夹持盘形记录介质，并且在盖子插入时通过盖的扩大开口进入与夹克一起进入再现装置的最内部。
