ABSTRACT:
A resinous member with a character visually arranged therein, including a resinous body, a character formed by a laser beam machining on a surface of the body, and a light transmittable coating arranged on the surface of the body for covering at least the character. The light transmittable coating is provided with a generally uniform thickness to form a roughened outer surface substantially corresponding to a machined surface of the character. The light transmittable coating may be formed through a spray coating process. The resinous member may be used as a key top member of a key in a keyboard of an electronic machine. The key top member comprises a resinous body, a character arranged on a surface of the body, and optical means arranged in association with the character for highlighting the character in an optical manner using an external light. The optical means may comprise a phosphorescent or fluorescent member.
