COMPUTER DISPLAY POINTING DEVICE CONTROL- LER

摘要

PURPOSE: To improve the operability of the controller by controlling both moving direction and speed of a display mark on a display in response to a direction detection means and a power detection quantization means. CONSTITUTION: When an operator pushes a key in the direction approximately equal to its desired moving direction, the signals showing the key pushing direction are outputted from the direction detection pads 38 and 46. A microprocessor 19 produces a direction control signal to move a pointer in the designated direction by means of the signals which are outputted when the pads 38 and 46 are touched and pressed. Then the power pierces through a detection pad 70 and is transmitted to the part under the pad 70. Thus the power is applied even on a force detection resistor. Therefore, a display mark can be moved at a high speed in a long distance and can be controlled at a low speed in a short distance respectively. As a result, the operability of the controller is improved.
