摘要： The present invention relates to a record playing device adapted to be attached to a cabinet of a record player.In order to facilitate the assembling of the record player as much as possible, the record playing device of the invention has a unit construction comprising a single base plate 1 which carries, at least: a turn table driving motor having a turn-table shaft and a pinion; a gear wheel for intermittent engagement with the pinion; a returning plate adapted to be moved reciprocatingly to the right and left in accordance with the rotation of the wheel gear; a sliding lever adapted to move reciprocatingly to the left and right to actuate link pawls pivoted to the gear wheel thereby to initiate the mutual engagement between the pinion and the wheel gear; and a microswitch for controlling the operation of the turn-table driving motor and adapted to be opened and closed in accordance with the positional relationship between the sliding lever and the returning plate.According to an aspect of the invention, the pinion attached to the turn-table shaft is fitted around a boss of the turn-table, thereby to reduce the thickness of the cabinet of the record player as much as possible.The present invention offers the following advantages: namely, the assembling of the record player is remarkably facilitated because the record playing section of the record player can be assembled simply by attaching the base plate to the cabinet of the record player and connecting the sliding lever at its one end to the operation plate attached to the tone-arm shaft. In addition, the overlapping of the pinion and the boss of the turn-table in the vertical direction is avoided to permit the thickness of the cabinet to be reduced correspondingly.
摘要翻译：本发明涉及一种适于附加到记录播放器的机柜的记录播放装置。为了便于记录播放器的组装尽可能地，本发明的记录播放装置具有单元结构，该单元结构包括单个基板1，该基板1至少具有：具有转台轴的转台驱动电机和小齿轮与齿轮间歇啮合的齿轮; 适合于根据所述轮齿轮的旋转而向左右移动的返回板; 滑动杠杆，其适于向左和向右往复移动以致动枢转于齿轮的连杆爪，从而开始小齿轮和齿轮之间的相互接合; 以及微型开关，其用于根据滑动杆和返回板之间的位置关系来控制转台驱动电动机的操作并适于打开和关闭。根据本发明的一个方面，附接到转台轴的小齿轮安装在转台的凸台周围，从而尽可能地减小了唱机的机柜的厚度。本发明提供以下优点：即，由于记录播放器的记录播放部分可以简单地通过将基板附接到记录播放器的机壳并将滑动杆连接到其一端连接到调音臂轴上的操作板。此外，避免了转台的小齿轮和凸台在垂直方向上的重叠，从而允许相应地减小机柜的厚度。

摘要： A tone arm moving mechanism is provided wherein the tone arm is normally moved over the lead in groove and lowered to the record during the last half of a normal record changing cycle. Means are then provided which are operative during a last record shut-off cycle for lowering the tone arm into a retaining means on the rest post, said retaining means being effective to restrain the tone arm from inward movement during the remaining portion of the last record shut-off cycle.

摘要： A record player having a turntable mounted for rotation on a frame; a pick-up arm spindle journalled to the frame, and having a pick-up arm and arm lever; and a control member for controlling movement of the pick-up arm in a first direction from the turntable and a second direction toward the turntable. A rod connected to the control member cooperates with a control element having a coupling portion for engaging the pick-up arm lever. Guides on the frame cause the coupling portion of the control element to move along first and second paths respectively during the first and second directions of pick-up arm movement, the paths being concentric with the axis of the pick-up arm spindle, and the coupling portion of the control element engaging the pick-up arm lever along the second path only.

摘要： An extremely simple record changer mechanism is provided wherein only two members interconnect the tone arm subassembly with the main cycling gear in the spindle area of the changer. One of these members is employed to lift and lower the tone arm and the other member is used for the dual purpose of moving the tone arm horizontally during the record changing cycle and also acts as a velocity trip actuating member during the playing cycle. Both members are designed to avoid damage to the mechanism if the tone arm is moved or restrained during the record changing cycle.The control knob normally used for ON-OFF-REJECT functions, is provided with a 4th position in which the record changer repeatedly plays a record on the turntable without shutting off the machine. This REPEAT PLAY position is reached by first moving the control knob to the ON or REJECT position and then moving it back to a position between the ON and OFF positions. When so moved, a detent force is provided for the control knob and an audible click is produced to inform the operator that the REPEAT PLAY position has been reached.
摘要翻译：提供了一种非常简单的记录变换器机构，其中只有两个构件将音臂组件与变换器的主轴区域中的主循环齿轮相互连接。这些构件中的一个用于提升和降低色调臂，另一个构件用于在记录改变周期期间水平移动色调臂的双重目的，并且在播放循环期间也用作速度跳闸致动构件。两个构件的设计是为了避免在记录更换周期中调音臂被移动或限制时对机构的损坏。通常用于ON-OFF-REJECT功能的控制旋钮设置有第四个位置，其中记录更换器在转盘上重复播放记录，而不关闭机器。通过首先将控制旋钮移动到ON或REJECT位置，然后将其移回到ON位置和OFF位置之间的位置，即可达到此REPEAT PLAY位置。当这样移动时，为控制旋钮提供制动力，并且产生可听见的点击以通知操作者已经到达了重复播放位置。

摘要： An automatic record player having a record changer by which a stack of records mounted on a changer spindle extending above the center of a turntable can be successively played out, wherein a cycle adjusting control is provided for enabling the record player to operate a predetermined number of times irrespective of the number of the records mounted on the changer spindle. To this end, there is provided an index wheel having a plurality of characters on its peripheral surface for showing the number of records left unplayed or the desired number of performance done by the record player in an operative association with the movement of the tone arm.
