摘要： A tape recorder or player with automatic azimuth control, utilizing a single pieozoelectric element inside the head's magnetic shield. A bimorph has one end rigidly connected to the head and the other end rigidly connected to the head support, for pivoting the head about an axis in line with the head gap.

摘要： An adjustable torsion-spring slipping clutch, especially useful for tape recorders, having first and second coaxial clutch sections which are rotatable about an axis of rotation. The second clutch section includes a sleeve which has a substantially circular cylindrical shape and is adjustable in diameter. A coaxially arranged cylindrical helical torsion spring is connected to one end to the first clutch section and its turns are wrapped around the sleeve, adjustment of sleeve diameter determining the torque to be transmitted between the clutch sections.
摘要翻译：特别适用于磁带录音机的可调式扭簧式滑动离合器具有能绕旋转轴线旋转的第一和第二同轴离合器部分。第二离合器部分包括具有基本上圆柱形形状并且可直径调节的套筒。同轴布置的圆柱形螺旋扭转弹簧的一端连接到第一离合器部分，并且其匝被套在套筒周围，调节套筒直径确定了将在离合器段之间传递的扭矩。

摘要： A cassette holder for Compact Cassettes, which is pivotable about a pivoting axis and intended for a vertical cassette recorder, is provided with stop means in order to avoid an incorrect position of the cassette, the openings in the front of the cassette, for the passage of the magnetic heads and the pressure roller, not being oriented towards the pivoting axis of the cassette holder but towards the insertion opening. In the cassette holder guide ridges are provided which co-operate with the cassette near its side walls and beside the locally thickened portion in the cassette, in such a way that during insertion the cassette is tilted from an oblique position to a straighter position, the top edge of the cassette holder butting against the locally thickened portion of the cassette in the case of an incorrectly inserted cassette.
摘要翻译：用于紧凑型盒式磁带的盒式磁带保持架可围绕枢转轴线枢转并且用于立式盒式磁带录像机，其具有停止装置，以避免磁带盒的不正确位置，磁带盒前部的开口用于通道的磁头和加压辊，不是朝向盒保持器的枢转轴线而是朝向插入开口。在磁带盒保持架中，提供了与磁带盒靠近磁带盒的侧壁和局部加厚部分配合的盒式磁带盒，这样一来，磁带盒在插入过程中就会从倾斜位置向更直的位置倾斜，在盒式磁带不正确的情况下，磁带盒的顶部边缘抵靠磁带盒的局部加厚部分。

摘要： A magnetic-tape player has a drive arrangement for winding a tape between two reel hubs. The drive arrangement can drive both reel hubs with different transmission ratios by a motor and four transmission devices. The drive arrangement is controlled entirely by a cam disc capable of counterclockwise rotation.
摘要翻译：磁带播放器具有用于在两个卷轴轮毂之间缠绕带的驱动装置。驱动装置可以通过电动机和四个传动装置驱动具有不同传动比的两个卷轴轮毂。驱动装置完全由能够逆时针旋转的凸轮盘控制。
