Zusammenfassung: | A bowling pin for use with an automatic scorer includes a wood core and an ionomer cladding having an outer surface which surrounds the standing portion of the pin. The pin includes a first fluorescent coating on the outer surface in a preselected area, preferably in the neck portion of the pin. This first fluorescent coating emits a relatively high level of visible light when subjected to ultraviolet light. A second fluorescent coating, which is colorless under ambient light, covers the standing portion of the pin, including the first fluorescent coating and emits a relatively low level of visible light, i.e., the moonglow effect. The second coating also allows the relatively high-intensity visible light which is emitted from the first fluorescent coating to pass therethrough for detection by an automatic scorer. |
