On the other hand, the output terminal of the ○R circuit 105 is also connected to one input terminal of the AND circuit 1 1 2, and its output terminal is connected to the other input terminal of the AND circuit 1 1 1.

Reference numeral 113 designates the other input terminal of the AND circuit 112, into which a signal is input by a switch that is activated when the tone arm reaches the performance end position. Next, the operations of the autoplayer configured as described above will be sequentially explained.

First, the record disc 5 is inserted into the weight bodies 1 and 2 from the position shown by the solid line in FIG. 1 or the one-dot chain line in FIG.

By providing a notch 10 in the lower slope 7, this insertion operation can be performed deep as shown by the two-dot chain line. In such a state, the leading edge of the record 5 reaches the lower part of the roller 35. Then, at the predetermined position where the code board is inserted, one of the sensors 90, 91, 92, and 93 is shielded, and the output signal of the OR circuit 101 is "
1", and together with the output signal "1" obtained by converting the output signal "0" of the ○R circuit 105 into the inverter circuit I06, the signal "1" is sent to the output side of the AND circuit 102.
"The motor 38 is driven via the amplifier, and an output signal "1" is also obtained from the output side of the other OR circuit 108, and the plunger 42 is driven via the amplifier 109. Therefore, the rotation of the motor 38 causes the roller 35 to rotate, and the bias of the plunger 42 causes the roller 36 to rotate.

When the sensors 90, 91, 92, 93 are unshielded, the drive of the motor 38 and the energization of the plunger 42 are released, and the motor 87 constituting the concentration device is driven, and the pulleys 86, 88 Via
The thin strips 70, 71, 72, 73 are pulled, and the sliding members 48, 49, 50, 51 are moved by the guide rails 44, 45, 45,
46, 47 toward the center of the turntable 17, and is pressed by the L-shaped plates 53, 54, 55, 56. The record 5 is guided onto the turntable 17 in such a way that it is placed upward, and a rough center positioning operation is performed in this way. Once this is completed, the plunger 2
9 is released, the elevating village 21 immediately descends under the elastic force of the coil spring 23, and the aforementioned protrusion 31 or 32 of the cord holding plate 34 is fitted into the center hole of the record disc 5, thereby accurately Center positioning is performed. When this is completed, the motor 87 is driven to rotate in the opposite direction, and the strings 70, 71, 72, 73 are pulled back, and the sliding members 48, 49, 50, 51 are retracted in the circumferential direction. . When the switch 89 detects the withdrawal, the motor 6 is driven to rotate. The rotational speed of this motor 6 is automatically determined by the sensor 94 detecting whether the record disc 5 on the turntable 17 is an LP disc or an EP disc. The well-known tone arm lead-in mechanism then operates. When the record 5 is played and the tone arm reaches the playing end position, the record holding plate 34 is raised, the switch is activated, and a signal "1" is input to the input terminal 113. and thus the above AN
A signal "1" is obtained at the output of the D circuit 1 1 2, and this is supplied to the other input terminal of the other AND circuit 1 1 1. Incidentally, since the output signal "0" of the AND circuit 102 is converted to "1" by the inverter 110, the output signal "1" is obtained at the 10,000 input terminals of the AND circuit 111. Therefore, the output signal of the AND circuit 111 becomes "1", which is supplied to the negative input terminal of the amplifier 107 to reverse the motor 38 and send a signal "1" to the output of the ○R circuit 108. is obtained, the plunger 42 is energized, and the turntable 1 is
While the record on 7 is held between the two rollers 35 and 36, it is guided in the opposite direction to the insertion/removal □4. The periphery of the record disc 5 is the above-mentioned notch 10.
When the above-mentioned code board 5 releases the shielding for the sensors 95 and 96, the motor 38 that rotationally drives the roller 35 is stopped and the roller 35 is stopped.
The pressing force of the roller 36 against the plunger 4
2 is released. Then, the periphery of the record 5 is picked up at the notch 101 and pulled out, thereby completing the ejecting operation. As described above, in the present invention, the first conveyance roller to which a driving force is applied by the driving means and the electromagnetic means are used to convey the conveyance to the guide path of the recording disk that connects the turntable and the recording disk exit. A carrying-out means is provided which includes a second carrying roller which is applied with a biasing force in the direction of pressure contact with the loaf, and a sensor is provided between the carrying-out means and the turntable. A first conveyance roller and a second conveyance roller sandwich the recording disk and guide it to the exit, and the recording disk passes through the sensor to release the shielding of the sensor by the recording disk. When this occurs, the driving of the first conveying roller is stopped and the urging force of the second conveying roller by the electromagnetic means is released. By setting the installation position to a predetermined position, when a part of a recording disc such as a record disc reaches a position where it can be taken out and protrudes from the outlet, the output of the sensor causes the set of rollers to move the recording disc This makes it possible to easily remove the recording disk by hand after being carried out by the carrying means, making it extremely easy to take out the recording disk. Since no time clamping force is applied, the possibility of damage can be extremely reduced.
