Vibration-transmitting tablet and coordinates input apparatus

Abstract

A coordinates input apparatus which detects vibration, inputted by a vibration-input pen, by a plurality of vibration sensors provided on a vibration-transmitting tablet, and derives coordinates of a vibration-input point based on vibration transmitting time on the vibration-transmitting tablet. The vibration-transmitting tablet comprises a glass substrate and two sheets of resinous film laminated on the glass substrate. The two sheets of resinous film are laminated on both surfaces of the glass substrate in an orientation such that the stretched directions of the resinous film differ for 90 degrees. By this, a vibration-transmitting tablet where sheets of protection film are laminated, and a coordinates input apparatus which minimizes the changes in vibration propagation velocity depending on the propagation directions, are realized.
