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： A rotating recording medium such as a video disc placed on a turntable is played back by a signal pickup head movable radially over and across the disc. Before and after the disc is played back, it is supported by a disc support over the turntable, the disc support being movable vertically between elevated and lowered positions. A switching mechanism has a single motor for selectively moving the signal pickup head and the disc support. While the disc support is actuated by the switching mechanism, the signal pickup head is locked against movement by a locking mechanism. Since the signal pickup head and the disc support are selectively actuated by the single motor, the overall construction is relatively simple and can be manufactured inexpensively. When the signal pickup head remains inactivated, it is locked in a standby position against undesired movement even when the apparatus is tilted or subjected to an impact.
摘要翻译：放置在转台上的旋转记录媒体例如视频盘通过径向跨过盘片的信号拾取头播放。在播放盘之前和之后，它由转盘上的盘支撑支撑，盘支撑件可在升降位置之间垂直移动。切换机构具有用于选择性地移动信号拾取头和盘支架的单个电动机。当盘支撑由切换机构致动时，信号拾取头被锁定机构锁定以防止运动。由于信号拾取头和盘支架由单个电动机选择性地致动，因此整体结构相对简单并且可以廉价地制造。当信号拾取头保持不活动时，即使当设备倾斜或受到冲击时，它也被锁定在备用位置以防止不期望的运动。

摘要： A recording reproducing apparatus reproduces a rotary recording medium which is accommodated within a jacket. The apparatus has a jacket opening enlarging device which is horizontally movable over a turntable, in the vicinity of a lateral inserting opening. For loading the recording, the jacket is inserted into the rear part of the reproducing apparatus where the record is captured and then the jacket is pulled out, leaving the record on the turntable. The jacket opening enlarging device comprises upper and lower enlarging members aligned with the inserting opening and pivotally coupled together to open and close by swinging upwardly and downwardly respectively. Fingers on the enlarging members project towards the inserting opening, which are close to each other when the jacket opening enlarging device is in the vicinity of the inserting opening. A rotating mechanism swingably opens the upper and lower enlarging members so that the fingers open the jacket engaging with rims as the jacket opening enlarging device moves toward the rear part. An enlarging member locking mechanism interlocks the upper and lower enlarging members for keeping them closed to shut the inserting opening when the jacket opening enlarging device is positioned in the vicinity of the inserting opening, and release the interlock upon insertion of the case.

摘要： A rotary recording medium reproducing apparatus comprises a turntable onto which a rotary recording medium is placed, a motor for rotating the turntable, a reproducing transducer for reproducing a recorded signal from the rotary recording medium placed onto the turntable, and a clamping mechanism for clamping the rotary recording medium on the turntable. The clamping device comprises a support structure capable of unitarily rotating with the turntable and moving up and down independently with the turntable, for supporting a part in the vicinity of a center hole of the rotary recording medium when the support structure is in a raised position, an elevating mechanism for moving the support structure upwards and downwards, clamping fingers provided on the support structure for clamping the rotary recording medium on the turntable at a part in the vicinity of the center hole of the rotary recording medium when the clamping fingers are operated, where the clamping fingers are supported at positions deviated from their centers of gravity so as to rotate towards a clamping releasing direction, and a receiving and stopping member for rotating the clamping fingers towards a clamping direction opposite to the clamping releasing direction by receiving and stopping parts of the clamping fingers when the support structure is lowered. The support structure is separated from both the elevating mechanism and the receiving and stopping member when the support structure is lowered. Further, the clamping fingers are applied with a rotational force in the clamping direction due to the weight of the support structure, to press the part of the rotary recording medium in the vicinity of the center hole thereof against the turntable.

摘要： A rotating recording medium such as a video disc placed on a turntable is played back by a signal pickup head movable radially over and across the disc. The disc is removably housed in a disc case composed of a jacket for containing the disc and a lid plate closing a slot in the jacket. When the disc case is inserted, it pushes a jacket opener over and across the turntable while the slot is opened by the jacket opener for removal of the disc. When the disc playback apparatus is not in operation or the disc is being played back, the jacket opener is firmly locked by a locking mechanism against movement into the apparatus, so that forced entry of a disc case into the apparatus is prevented. Since the jacket opener is locked at laterally spaced positions by the locking mechanism, the jacket opener is rigidly kept in the locked position against the operator's undue attempts to insert the disc case.
