Claims

[Scope of Claim for Utility Model Registration] (1) A drive gear is attached to the drive shaft suspended horizontally on the music box base, and the drive gear rotates a rotating disk, and the protrusions provided on the rotating disk generate various vibrations. A rotating disk-shaped music box that rotates a ratchet wheel facing the plate and plays a diaphragm with the ratchet wheel to produce a sound,
A mounting plate formed in a size that can cover the mechanical parts of the music box except for the rotating disk is attached and fixed on the music box base, and a window is placed on the mounting plate in the part facing the ratchet wheel and drive gear. In addition to providing a hole, a support shaft for removably attaching a rotating disk is provided protruding from a portion located on an extension line of the drive shaft, and
On the mounting plate, the base of a presser arm extending in the direction of the support shaft is rotatably mounted on the extension line of the drive shaft and on the opposite side of the support shaft. 1. A music box device comprising: a presser protrusion projecting from the lower surface of the presser arm placed under the action of a spring. (2) The music box device according to claim 1, wherein the tip of the presser arm is formed in a hook shape that can be freely engaged with and detached from an annular groove provided on the support shaft. (3) The music box device according to claim 1, wherein the presser arm is rotatable in vertical and horizontal directions. (4) The music box device according to claim (1) of the utility model registration, wherein the presser arm is covered by a cover body.
