Abstract

See full text

The present invention provides a digitizer for a fingertip tactile-sense input device to which switches can be added without having to increase the number of wires. A first lower right contact (33b) and a second lower right contact (33c) are placed respectively on the first and second resistive sheets (10a, 20a) at specified positions that are separated to the right from the control area (11, 21) so that they form a lower right switch (33), with the first lower right contact (33b) being connected to the bottom edge electrode (11b) and the second lower right contact (33c) being connected to the right edge electrode (21a); and a first upper left contact (34b) and a second upper left contact (34c) are placed respectively on the first and second resistive sheets (10a, 20a) at specified positions that are separated to the left from the control area (11, 21) so that they form the upper left switch (34), with the first upper left contact (34b) being connected to the top edge electrode (11a) and the second upper left contact (34c) being connected to the left edge electrode (2b).
