Abstract
Abstract A dish for supporting a light blocking object such as a coffee cup, a tea cup or the like, having a melody sounding function is disclosed, in which the dish below its object supporting surface is provided with a melody sounding means proximate to the object supporting surface for producing and playing a given melody for a predetermined time by means of a switching mechanism including a photosensor. The melody is automatically produced on removing the object from the dish and exposing the photosensor of a melody sounding means to the light passing through the dish of light permeable material.

Claim 1
Independent Claim
175 words
A dish having a melody sounding function and comprising a bottom wall of predetermined thickness and an annular wall outwardly flared from the bottom wall, at least said bottom wall for its entire extent being light permeable throughout its thickness and having an upper surface adapted to receive a light blocking object, a melody sounding means supported below said bottom wall of the dish in proximate relation to said bottom wall for producing a melody for a predetermined time, means for thus supporting the melody sounding means, and means forming part of the melody sounding means and comprising a photosensor normally exposed to light through the light permeable bottom wall of the dish for initiating production of a melody when said photosensor is impinged by light as occurs when the dish is free of the light blocking object, said melody supporting means comprising a plate mounted to the dish in relation to its bottom wall to define a space between the plate and the bottom wall in which space said melody sounding means is received.
