Abstract

PURPOSE:To make a recording player of one-point turning type small-sized by using a mechanism which repeats the start state and the stop state alternately independently of the position of a pickup arm. CONSTITUTION:A driving auxiliary plate 21 which can be rotated in a certain range is arranged on a driving plate 12, and a switch control piece 14 is so arranged that it rubs the peripheral part of the driving auxiliary plate 21. The mechanism repeating the operation, where the switch control piece 14 rotates a moving piece 13 to start the pickup at the first time and does not rotate the moving piece 13 to stop the pickup at the second time, is used. Since the switch control piece 14 repeats the start state (the moving piece 13 is raised) and the stop state (the moving piece 13 is not raised) alternately independently of the position of a pickup arm 15 in this manner, a rest position and an LP record start position can be placed close to each other, and consequently, the player of one-point turning type is made small-sized.

引っかかり保持されている。Structure of the conventional example and its problems FIGS. 1 to 3 show an example of a conventional star/stop switching device. In Figure 1, 1 is a turntable shaft, and this shaft and small gear 2 are coaxial, and can mesh with the main gear 3 when the turntable rotates 2 and starts up, but during other normal performances. Main gear 3 has 3 missing teeth so they do not mesh. The start lever 4 is caught and held by a stopper 5.

る。A cam (not shown) is formed on the back surface of the main gear 3, and the drive plate 12 starts moving in the direction of arrow F along this cam, and a movable piece rotatably disposed on the drive plate 12 moves along the cam. The distal end tS(a) of the switch control piece 13 hits the switch control piece 14, causing the moving piece 13 to rotate clockwise, and the drive pin 16, which is integrated with the pickup arm 16, is sandwiched between the drive comb 17 and this state is removed from the plate. It is held by a spring 18. FIG. 2 shows a state in which the movable piece 13 is thus rotated clockwise 7 and grips the drive pin 16. Thereafter, as shown in FIG. 2, the t-i drive plate 12 holding the drive pin 16 returns in the direction of arrow G along a cam (not shown), so that the pickup arm 16 is carried toward the center of the turntable.

ジに側圧がかかり針飛びをおこしでし捷う。At this time, the control pin 19 fixed to the pickup arm 15 rotates the switch control piece 14 in the direction of arrow H and passes beside the switch control piece 14 . Therefore, it is absolutely necessary to keep a certain distance between the armrest position and the start position of the LP record. If the position at which the switch control piece 14 is rotated is beyond the star 1 position of the LP record, lateral pressure will be applied to the cartridge of the pickup arm 16 during performance, causing needle skipping and twisting.

The moving piece 13 does not collide with that. Therefore, the drive pin 16 is pushed by the drive rubber 17, and the pickup arm 16 returns to the rest position. At that time, the control pin ] 9 rotates the switch control piece 14 clockwise, and the lock part 20
Remove the one that was caught in the mechanism and turn the power switch 8 off.

ヤを小型化する上での大きなネックとなっていた。In this way, in the conventional configuration, for the reason mentioned above, a certain distance must always be maintained between the rest position and the start position of the LP record, which is a major problem in downsizing the single-point rotation type record player. It was becoming a bottleneck.

ーヤの外形寸法を小型てすることができるものである。Structure of the Invention In the present invention, a drive auxiliary plate that can rotate within a certain range is arranged on the drive plate, and the switch control piece is arranged so that it rubs around this drive auxiliary plate. By using a mechanism in which this switch control piece repeats the operation of rotating the moving piece the first time to start the pickup, and the second time stopping the moving piece without fully rotating it, the position of the pickup arm is adjusted to the starting position. It is independent of the stop switching mechanism, and the external dimensions of the single-point rotation type player can be made smaller.

第５図のように移動片が時計方向に回転する。FIG. 4 shows the state in which the power is off, and when the start button is pressed in the same manner as in the conventional example, the power is turned on and the drive plate 12 begins to move in the direction of arrow J. The tip 14(a) of the switch control piece 14 bends and passes the right side of the drive auxiliary plate 21 which can rotate on the drive plate 12, and the movable piece 13 and the switch control piece 14 collide.
The moving piece rotates clockwise as shown in FIG.
