  • Publication number: 20160236975
    Abstract: A cover glass for a pen input device has a haze value of less than 1%, and a Martens hardness within a range from 2000 N/mm2 to 4000 N/mm2. When a moving member receiving a load of 150 gf (1.47 N) is moved in one direction, at 10 mm/sec, at room temperature, on the surface of the cover glass, a coefficient of kinetic friction ?k of a kinetic frictional force Fk (N) exerted by the cover glass surface within a region where an approximately linear relationship is established between the kinetic frictional force Fk (N) and the time is 0.14˜0.50, and a standard deviation ? (N) of the kinetic frictional force Fk (N) is no more than 0.03. The moving member is a pen that includes a pen tip made of polyacetal resin with a Rockwell hardness of M90 and having a radius of curvature of 700 ?m.
