ABSTRACT:
In an input device, switches are disposed at points of intersection of an n.times.m matrix, a scanning signal is applied from rows or columns of the matrix, and an operated switch is detected by detecting the scanning signal output from rows or columns. In detecting the operated switch, the detected switches may include the actually-operated switch and a pseudo-operated switch. The input device can prevent the detection of a pseudo-operated switch.
