ABSTRACT:
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.
