Abstract
Abstract A synthetic resin moulded product has a moulded label equivalent portion having mirror-like smooth surface parts with a pattern and coarse surface parts in parts other than the pattern. The coarse surface parts have extremely small minute projections and depressions over the whole surface thereof, and also undulating uneven parts with another pattern. The label equivalent portion indicates the one pattern by a contrast of the lusterless parts formed by the coarse surface and the lustrous parts of the smooth surface, and at the same time indicates another pattern by the undulating uneven contour in the coarse surface. The manufacturing method forms the synthetic resin moulded product with the label equivalent portion.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
181 words
A synthetic resin moulded phonograph record disc having a label equivalent portion formed integrally therewith during a moulding process and formed in a part other than the sound grooves of said phonograph record disc, said label equivalent portion comprising coarse surface parts having a surface with minute projections and depressions thereon, smooth light reflecting surface parts having smooth surfaces, said smooth surface parts forming a predetermined pattern against a background of said coarse surface parts, the depth of the projections and depressions in said coarse surface parts being in a range of 1-5 Mu and the width thereof in a range of 5-15 Mu , and uneven parts formed on said coarse surface parts with another pattern having projections and depressions which are much larger than the projections and depressions of said coarse surface parts, said coarse surface parts being lusterless due to the irregular reflection of light theRefrom and said smooth surface parts having a luster of mirror-like reflectivity whereby the predetermined pattern is recognized by the contrast between the lusterless coarse surface parts and the lustrous smooth surface parts.
Claim 2
Dependent Claim
181 words
A synthetic resin moulded phonograph record disc having a label equivalent portion formed integrally therewith during a moulding process and formed in a part other than the sound grooves of said phonograph record disc, said label equivalent portion comprising coarse surface parts having a surface with minute projections and depressions thereon, smooth light reflecting surface parts having smooth surfaces, said smooth surface parts forming a predetermined pattern against a background of said coarse surface parts, the depth of the projections and depressions in said coarse surface parts being in a range of 1-5 Mu and the width thereof in a range of 5-15 Mu , and uneven parts formed on said coarse surface parts with another pattern having projections and depressions which are much larger than the projections and depressions of said coarse surface parts, said coarse surface parts being lusterless due to the irregular reflection of light theRefrom and said smooth surface parts having a luster of mirror-like reflectivity whereby the predetermined pattern is recognized by the contrast between the lusterless coarse surface parts and the lustrous smooth surface parts.
Claim 3
Dependent Claim
24 words
The synthetic resin moulded phonograph record disc as defined in claim 1 wherein said predetermined pattern indicates letters and said other pattern indicates figures.
Claim 4
Dependent Claim
49 words
The synthetic resin moulded phonograph record disc as defined in claim 1 wherein said label equivalent portion further comprises depressed parts which are below the level of said smooth surface parts, said coarse surface parts and said uneven parts being formed on the bottom surface of said depressed parts.
