Claims

[Scope of utility model registration request]

(1) A vibration system support structure for a pickup cartridge that supports a vibration system including a cantilever so as to vibrate freely with respect to a frame, wherein the vibration system is fixed to the cantilever and the frame, respectively, and at least one protrudes toward the other side at the center thereof. and a damper that is baked and fixed to the first and second members and interposed between the first and second members. A vibration system support structure for a pickup cartridge characterized by vibrating with the tip as a fulcrum.

(2) The vibration system support structure for a pickup cartridge according to claim 1, wherein the protrusion has a pointed shape.

(3) The damper has a configuration in which one of the fixed surfaces is inclined relative to the other in a plane in the direction of applying stylus pressure that includes the central axis of the cantilever, and the two fixed surfaces are mutually moved by the application of stylus pressure. A vibration system support structure for a pickup cartridge according to claim 1, wherein the structures are parallel to each other. {4} A claim for registration of a utility model, characterized in that each fixing surface of the first and second members and the damper has a shape in which a dimension in the plane is smaller than a dimension in a plane orthogonal to the plane. A vibration system support structure for a pickup cartridge according to scope 1.
