摘要： An apparatus for reproducing rotary recording media has an inserting opening on its front side. A rotary recording medium is accommodated within a case having a jacket and a lid member for closing an opening of the jacket. The apparatus has a mechanism for enlarging the opening of the jacket as it is inserted into the opening. This mechanism couples with the jacket as it moves over a turntable positioned between the inserting opening and a rear part of the reproducing apparatus. A switch mechanism (comprising a microswitch) detects a movement of the jacket opening enlarging mechanism. The microswitch is positioned opposite the jacket opening enlarging mechanism and near the inserting opening. The microswitch remains operated as long as the jacket opening enlarging mechanism is moved away from the inserting opening. The microswitch returns to normal when the jacket opening enlarging mechanism moves back to its normal position near the inserting opening.
摘要翻译：用于再现旋转记录介质的装置在其前侧具有插入开口。旋转记录介质容纳在具有用于封闭外壳的开口的护套和盖构件的壳体内。该装置具有用于在夹套插入开口时扩大外套的开口的机构。这种机构在护套移动到位于插入口和再现装置的后部之间的转台上时，与外套相结合。开关机构（包括微动开关）检测护套开口扩大机构的运动。微动开关位于套管开口扩大机构的对面并靠近插入口。只要护套开口扩大机构从插入口移开，微动开关就保持操作。当夹套开口扩大机构返回到插入口附近的正常位置时，微动开关恢复正常。

摘要： Information signals are reproduced from a disc-shaped recording medium which was accommodated within a case. The case has a jacket with space for accommodating the disc-shaped recording medium therein and an opening through which the disc-shaped recording medium can enter and leave the jacket. A lid member may be inserted through the opening of the jacket for covering and closing the opening. The apparatus for reproducing the disc comprises an inserting opening through which the case is manually inserted. A holding mechanism holds either the disc-shaped recording medium or the lid member at an innermost part of the reproducing apparatus and on the side opposite of the inserting opening. A turntable is located between the inserting opening and the holding mechanism. A push-back mechanism includes energy storing members which are urged responsive to a disc insertion operation in which the case is inserted through the inserting opening and into the innermost part of the reproducing apparatus. The case is pushed back responsive to a release of the pushing and inserting force acting on the case. The push back occurs in response to a use of the stored energy forces. The case is pushed back in a direction which is opposite to the direction of the insertion of the case, so that after push back a part of the case projects outwardly from the inserting opening.

摘要： An optical disc drive system in which the empty sleeve component of an optical disc cartridge is utilized to lock the optical disc in its operational position while occupying a storage location within the drive system. The locking/storage feature is achieved by providing adjacent to the conventional disc insertion opening in the drive frame an additional opening for receipt of the empty sleeve component and by providing guides within the drive for positioning the empty sleeve over the optical disc. The empty sleeve cooperates with a spring loaded frame/disc lowering mechanism which lowers the optical disc to the drive spindle where it is held by a magnetic force generated by a magnetized portion of the spindle. The sleeve also cooperates with a frame/sleeve latching mechanism to facilitate withdrawal of a frame supported optical disc from the sleeve and reinsertion of the frame supported optical disc back into the sleeve. A plurality of spring loaded members support the frame member before the sleeve actuates the lowering mechanism and free the optical disc from the spindle upon withdrawal of the sleeve from its locking/storage position.
