Abstract

PURPOSE:To vary the cursor moving spped by providing four pulse generating means, which generate pulses having frequencies corresponding to magnitudes of output signals from respective depression detecting parts, and an output means for input to a host computer and varying the frequency of the generated pulse in accordance with the extent of depression. CONSTITUTION:When a prescribed point of a plane prate 1 is depressed, this point is moved downward with a pole brace 4 as the fulcrum to reduce the resistance values of depression detecting parts. Pulse generating means generate pulses having a high frequency corresponding to resistance values. When depression is stopped, a spring 5 acts to return the plane plate 1 to the horizontal state, and resistance values are made infinite, and then, each pulse generating means stops pulse generation. That is, when an arbitrary position of the plane plate 1 is depressed, the current value or the like is changed in accordance with the extent of depression, and pulse generating means change the frequencies of generated pulses in accordance with the change of resistance values or the like, and a signal is sent to the computer from the output means to move the cursor.
