<p>PURPOSE:To decrease the space of an operating section by outputting a cursor control signal to one point or the movement of that point on a solid-state mouse face to attain ease of cursor position control and efficient data input. CONSTITUTION:In pointing out a face of the solid-state mouse 4, an output 9 is at an H level and outputs 11, 12 represent analog signals at the point. A leading detector 5 detects a clock signal 13 when the output 9 goes to the H level and a signal 10 is outputted as the H level. A latch circuit 6 latches the state of the signals 11, 12 every time a clock 13 is inputted and outputs the content latched before as the signals 14, 15. A subtractor 7 subtracts signals 11, 12 and 14, 15 respectively and outputs signals 16, 17. A converter 8 outputs a cursor control signal 18 proportional to the level of the signals 16, 17 when the signal 10 is at the H level and the clock 13 is inputted and it is displayed on a CRT display connected to a CPU.</p> |
