2. A cartridge 13 was attached, and a weight 14 was attached to the rear end of the rear arm. When a tone arm is attached to a player case, a space is required to allow the weight side to rotate freely, so the upper surface area of the player case becomes large, which has the disadvantage that it is difficult to reduce the tone arm to the jacket size. It was hot.

As shown in Fig. 3, the weight 2 mounting arm 4 is placed on the side of the cartridge 1 mounting arm 3, the drum 9 is mounted on the end of the front part 3 of the arm to which the cartridge 1 is mounted, and the rear part of the arm to which the weight 2 is mounted. The drum 10 attached to the end of the drum 4 is pivotally connected to the U-shaped mounting frame 6 attached to the rotating shaft 5 by mounting shafts 7 and 8, and both drums 9 and 10 are pulled by a tome arm as if being indexed by a thread 11. be.

上効果がある。 Since the present invention has the structure described above,
No space is required behind the tone arm rotation axis, making it suitable for jacket-sized players. Further, since the cartridge side arm vibration system and the weight side vibration system are separated and connected by a thread, vibrations on the weight side are not transmitted, which is effective in countering resonance.

本考案はドラム９，１０を糸で結合する以外に
歯車、摩擦車等で結合する場合も考えられる。 In the present invention, in addition to connecting the drums 9 and 10 with a thread, it is also possible to connect the drums 9 and 10 with gears, friction wheels, etc.

策上の効果もある工業上有益な考案である。 As mentioned above, this invention has no weight behind the rotation axis of the tone arm and can be compactly assembled, making it possible to miniaturize record players and convert them into jacket-sized players. This is a very useful idea.

Claims

[Scope of utility model registration request]

A drum 9 attached to the end of the front arm 3 to which the cartridge 1 is attached and a drum 10 attached to the end of the rear arm 4 to which the weight 2 is attached are pivoted to a U-shaped mounting frame 6 attached to the rotation shaft 5. The tone arm was attached and pulled as if it were indexing both drums 9 and 10 with a string 11.
