摘要： The cover of a cassette such as a magnetic tape cassette is pivoted in either of two opposite directions to open positions about a single axis. To latch the cover, adjacent each side wall of the cassette there is a cover flange having a circular slot concentric with the pivot axis, the slots in the two flanges extending in opposite directions and overlapping at ends which, in the closed cover position, are aligned with latching projections on the cassette housing. By moving one latching projection out of its slot, the cover is free to pivot in the direction in which the other projection engages the slot at its end. In a flip-over reversible cassette, one unlatching member on the apparatus will engage the correct latching projection, depress and release it, so as to permit the cover to open only the correct direction. When the cover is fully opened, the projection may be permitted to be reinserted, into a recess provided for that purpose.

摘要翻译： 诸如磁带盒之类的盒式磁带的盖子在两个相反的方向中的任一方向上枢转以围绕单个轴线打开位置。 为了锁住盖子，在盒子的每个侧壁附近都有一个具有与枢转轴线同心的圆形槽的盖凸缘，两个凸缘中的狭槽在相反的方向上延伸并且在封闭盖位置的端部处重叠 与盒壳体上的闩锁突起对准。 通过将一个闩锁突出部从其槽中移出，盖可以在其另一个突起在其端部与狭槽接合的方向上自由枢转。 在翻转的可逆盒中，装置上的一个解锁构件将接合正确的闩锁突起，按压并释放它，以便允许盖仅打开正确的方向。 当盖完全打开时，可以将突起重新插入到为此目的而设置的凹槽中。

摘要： A device having a pivotal cover, such as a magnetic tape cassette, for covering one or more front openings between the front edges of two major walls which extend generally parallel away from the opening. The cover has flanges by which it is connected at the sides of the device, through a pivot pin and a straight slot, on the pivot axis, and another pin which engages a circular segment slot. The circular segment slot has a recessed portion which the other pin engages when the cover is closed. The cover must be moved in a direction away from both major walls, to an unlatched position, before it can be pivoted to an open position adjacent one or the other of the major walls.

摘要： A magnetic-tape cassette has a front opening (7) which when the cassette is not in use is covered by a pivotal front cover (20) and a sliding plate (9) which is situated on the outside of the cassette housing (1) adjacent the bottom wall (2) thereof. In the closed position the sliding plate covers the front opening (7) at the bottom and a part of the magnetic tape (18a) which extends across said opening. The top wall (3) of the housing is imperforate and is contiguous with the front cover in the closed position of the cover. In the closed position the sliding plate (9) extends from the front of the cassette housing (1) beyond openings (4) in the bottom wall (2) to cover these openings. The sliding plate is formed with two apertures (15) which expose the openings (4) in the open position of the sliding plate (9). In the closed position the sliding plate (9) is latched by means of at least one latching member (27) which comprises a latching portion (29) and an actuating portion (30), the latter projecting into a slot or groove (32) in the sliding plate (9) near the rear end of the slot or groove when this plate (9) is in the closed position.

摘要翻译： 磁带盒具有前开口（7），当未使用盒时，前盖（7）被位于盒壳（1）外侧的枢转前盖（20）和滑板（9）所覆盖， 邻近其底壁（2）。 在关闭位置，滑板覆盖底部的前开口（7）和覆盖所述开口的磁带（18a）的一部分。 外壳的顶壁（3）是无孔的，并且在盖的关闭位置与前盖邻接。 在关闭位置，滑动板（9）从盒壳体（1）的前部延伸超过底壁（2）中的开口（4）以覆盖这些开口。 滑动板形成有两个开口（15），这些孔将开口（4）暴露在滑板（9）的打开位置。 在关闭位置，滑动板（9）通过至少一个闩锁构件（27）闩锁，闩锁构件（27）包括闩锁部分（29）和致动部分（30），后者突出到槽或凹槽（32）中， 当该板（9）处于关闭位置时，在滑槽（9）中靠近槽或凹槽的后端。
