Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rest for a tone arm of a record player, and particularly to a rest that allows a turntable to stop or rotate when the tone arm is placed on the arm rest.

The armrest of a conventional record player is designed so that when the arm is held, the turntable stops dynamically, so for example, when the turntable is rotated,
\This has the disadvantage that it is difficult to clean it with a record cleaning device.

The present invention aims to provide an armrest that eliminates the above-mentioned drawbacks, and its feature is that the arm is placed on the armrest, and in addition to operating the switch for stopping rotation of the turntable at the time of h, the arm is placed on the armrest. It is designed so that the record can be cleaned using the rotation of the turntable by providing a part where the stop switch does not operate even when the record is turned.

The present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a plan view of the present invention, in which a record 2 is placed on a turntable 1, a tone arm 3 for pickup has a cartridge 4 at one end, a counterweight 5 at the other end, and a stand. The tone arm 6 is rotatable horizontally and vertically about the center point 6.

The armrest 7 has tone arm rests 7a and 7b, and when the tone arm 3 is at the position shown by the solid line, the turntable 1 is in a stopped state, and when the tone arm 3 is at the position shown by the dotted line, the turntable is in a rotated state, and the record cleaner 8 is The record disc can be cleaned by manually or automatically disposing it on the record disc 2.

In the present invention, in order to achieve the above-mentioned configuration, a cam 6a is pivotally attached to the shaft of the stand 6, and a switch 10 is disposed opposite to the long axis of the cam.

The switch is pressed by one end of the cam 6a so that the switch is
Therefore, when the tone arm 3 is placed on the rest 7a of the armrest 7, the circuit connected from the power source 11 to the turntable motor 9 through the switch 10 is cut off, and the motor stops rotating. Also tone arm 3
If the cam 6a is moved to the mounting portion 7b of the armrest 7, the cam 6a
is separated from the contact piece of the switch 10 and operates as shown by the dotted line in FIG. 2, so the circuit becomes conductive and the motor 9 continues to rotate.

Since the present invention is configured as described above, it is possible to have the conventional armrest function and cleaning function in the same manner depending on the position on the armrest, and its practical effects are great.

[Brief explanation of the drawing]

FIG. 1 is a plan view for explaining the armrest of the present invention, and FIG. 2 is a schematic diagram illustrating the operation of the main parts of the present invention. 1 is the turntable, 3 is the tone arm, 6a is the cam,
7 is an armrest, and 10 is a switch.

Claims (1)

[Scope of utility model registration request] A first tone arm rest and a second tone arm rest are provided for placing the tone arm on the arm rest, and the turntable is driven when the tone arm is placed on the first tone arm rest. the motor to be stopped,
The armrest is characterized in that when a tone arm is placed on the second tone arm placing portion, the motor is rotated to clean a record placed on the turntable.
