    • An ink ribbon cassette for impact type printers comprises an ink roller of plastic sponge impregnated with ink and an endless type ink ribbon contacting with the ink roller. The ink ribbon is provided with a proper tension by a leaf spring member. At the time of assembly, the pressure of the leaf spring on the ribbon is not yet impressed. After the setting of ribbon, the bow-shaped leaf spring is reversed to opposite side in a snap action, being pushed from the outside, thereby to impress the tension. In another example, when the ink volume impregnated in the ink ribbon decreases after long use of the cassette, pressure is applied to the ink roller by the spring member, by changing the side of it bow part and squeezing ink to transfer to the ink ribbon, thereby prolonging the service time of the ink ribbon.
    • 用于冲击式打印机的色带盒包括浸渍有油墨的塑料海绵的墨辊和与墨辊接触的环形墨盒。 墨带由片簧构件提供适当的张力。 在组装时,丝带上的板簧压力尚未印证。 在设置色带之后,弓形板簧在快动作中被反向到相对侧,从外部推动,从而使张力受到打击。 在另一个实例中,当长时间使用墨盒后,浸渍在墨带中的墨水体积减小时,通过弹簧部件对墨辊施加压力,通过改变其弓形部分的侧面并挤压墨水以转移到墨带 从而延长墨带的使用时间。

    • A stationary record player is described having a turn table adapted to be rotatably driven by an electric motor. A pickup is pivotally secured to the turn table, the pickup having a stylus which moves along the recording groove of a stationary record medium when the pickup is rotated together with the turn table whereby the signal on the record medium is reproduced. The record player comprises a lift member adapted to detect the arrival of the stylus at the final position of reproduction, the lift member including a lift lever being pivoted to the turn table. One end of the lift lever is held by the pickup until the pickup reaches a final inward position whereby the one end is released allowing the remaining end of the lift lever to be pivoted upward. A play lever for operating a switch for supplying current to the electric motor is locked during play, and when the stylus reaches the final playing position, an activating arm of the locking mechanism is moved by the remaining end of the lift lever to release the lift lever stopping the electric motor.
    • 描述了具有适于由电动机可旋转地驱动的转台的静止记录播放器。 拾取器被枢转地固定到转台上,当拾取器与转台一起旋转时,拾取器具有沿着静止记录介质的记录槽移动的触针,由此再现记录介质上的信号。 记录播放器包括适于检测触针到达再现的最终位置的提升构件,提升构件包括枢转到转台的提升杆。 提升杆的一端由拾取器保持,直到拾取器到达最终的向内位置,由此一端被释放,允许提升杆的剩余端向上枢转。 用于操作用于向电动机提供电流的开关的游戏杆在游戏过程中被锁定,并且当触控笔到达最终播放位置时,锁定机构的启动臂由提升杆的剩余端移动以释放升降机 杠杆停止电动机。

    • A loudspeaker consisting of a driver or motor unit consisting of a cylindrical magnet structure, a voice coil and a domed diaphragm; an enclosure unit for receiving therein the driver or motor unit; and a horn unit attached mechanically to the opened end of the enclosure unit, the positioning or locating cylindrical section of the horn unit being snugly fitted into the enclosure unit. The assembly is much facilitated, and the driver or motor unit, the enclosure unit and the horn unit may be located and held in correctly mutually coaxially aligned relationship in a very simple manner. In one embodiment, a spring is loaded between the driver or motor unit and the enclosure unit so that the domed diaphragm may be restrained under the forces in excess of 1.5 kg/cm.sup.2 over which the lowest resonance frequency may be stabilized.
    • 扬声器由由圆柱形磁体结构,音圈和圆顶膜片组成的驱动器或电机单元组成; 用于在其中接收驱动器或马达单元的外壳单元; 以及机械地附接到外壳单元的开口端的喇叭单元,喇叭单元的定位或定位圆柱形部分紧密地装配到外壳单元中。 该组件非常方便,并且驱动器或马达单元,外壳单元和喇叭单元可以以非常简单的方式定位和保持在正确的相互同轴对准的关系中。 在一个实施例中,弹簧被加载在驱动器或马达单元与外壳单元之间,使得圆顶隔膜可以在超过1.5kg / cm 2的力的作用下被抑制,在该力下可以稳定最低的共振频率。

    • A stationary record player having a turn table and a pickup pivotally secured to the turn table, so as to trace, when rotated together with the turn table, the recording groove of a stationary record medium on which the record player as a whole is placed. The record player has various novel functions such as an automatic stopping function for automatically stopping the player when the play is finished with the record medium, an automatic returning function for automatically resetting the stylus to the starting position, a lift-stop function for automatically stopping the player when the latter is lifted up from the record medium a slide-stop function for automatically stopping the player when the latter is displaced laterally from the correct mounting position on the record medium, a pause state eliminating function for stopping the player when the latter in the pause state is lifted up from the record disc, and so forth. These functions are effective to prevent the unnecessary wear of the stylus and to protect the latter from any damaging external force. Further, the force required for turning the player into operation is derived from a motor for driving the turn table, so as to obtain an improved operability of the player. The playing performance of the player is further improved by an additional provision of an end repeat and optional repeat functions by means of which the playing is performed repeatingly over the full or a desired part of the record medium.
