    摘要: In a panel (1a) of a touch panel (1), a coordinate axis x is set by connecting points A and B that are current observation points. When a designated point P is designated on the panel (1a), currents (i1) and (i2) corresponding respectively to a distance between the designated point P and the point A and a distance between the designated point P and the point B flow respectively to a resistive film between the points P and A and a resistive film between the points P and B by voltage sources (e1) and (e2), and a sum of these currents flows to an impedance Z connected to the designated point P. A coordinate x of the designated point P is calculated by detecting the currents (i1) and (i2).

    摘要: There is provided an input device using a touch panel allowing input operations to be performed without viewing an input surface. The input device includes a transparent capacitance-type touch panel (12) formed in the shape of a dome, and a liquid crystal panel (14a) disposed on the back side of the touch panel. The position detection processing portion (20) applies predetermined voltage to four terminals (T1 to T4) of the touch panel, and detects current flowing via each terminal to detect the coordinates of a point on the touch panel operated by the operator's finger (100) based on the detected current value. The data processing portion (30) causes a liquid crystal display device (14) to display an operation screen, including graphics, symbols, etc., which correspond to inputtable operations, based on a status signal Sst from electronic equipment in which the input device is used, and the data processing portion determines the content of an input operation performed by the finger pressing the touch panel, based on a position signal Spos indicating the coordinates of the operation point and the status signal Sst. The present invention is suitable for input devices using a touch panel.
