To present a coordinates input device simplified in construction and outstandingly improved in utility. In a panel member of a coordinates input device, a first input unit and a second input unit are set on a pair of transparent electrodes and the first input unit allows to input by a member of a relatively large pressing pressure per unit area by using a tapered pen piece. The second input unit allows to input by pressing with a member of a relatively small pressing pressure per unit area such as the finger, not limited to the pen member. To present a coordinates input device enhanced in the reading precision of pressing position by accurately measuring the pressing level at the pressing position. This device possesses a structure in which conductive X-direction resistive film and Y-direction resistive film overlap with each other across a tiny clearance, and when the pressing position is pressed, switch opening or closing is controlled by a specified procedure, and the X-direction and Y-direction levels of the contact resistance obtained by pressing of the position are detected, and when the pressing levels are sufficient, the switch opening or closing is controlled by the next procedure, and the coordinates of the pressing position by measured voltages can be measured.
