JPS6459418A - Coordinate input device - Google Patents

Abstract

PURPOSE:To simplify the constitution of a device and to reduce cost, by detecting a vibration inputted to a vibration transfer material from a vibration pen, by a vibration sensor installed in the vibration transfer material through an installing means, and determining a coordinate of an input pen from its vibration transfer time. CONSTITUTION:The titled device is provided with a vibration transfer material 8, a vibration pen 3 for inputting a vibration to this vibration transfer material 8, plural vibration sensors 6 being attachable and detachable to and from the vibration transfer material 8, and a means for setting fixedly each relative position of these vibration sensors 6, and also, installing the vibration sensors 6 to the vibration transfer material 8 through an adsorbing means. In such a state, by the vibration sensor 6 which is installed in the vibration transfer material 8 through this installing means, a vibration which is inputted to the vibration transfer material 8 from the vibration pen 3 is detected, and from its vibration transfer time, a coordinate of an input pen is determined. In such a way, as for the vibration transfer material, that of a desired material can be utilized, and each part required of the device can be made small in size and light in weight, therefore, the portability of the device can be improved greatly.
