ONE-OPERATION BUTTON MECHANISM AND APPLICATION SOFT STARTING METHOD USING THE MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide an one-operation button mechanism eliminating the necessity of a power supply for a keyboard controller, and an application soft starting method using the mechanism. SOLUTION: A depression signal generated when a false button depression circuit connected by a keyboard scanning line 4 to be a matrix on a keyboard depresses a button A is detected, a prescribed key scanning line 4 is connected to a keyboard controller 1 by outputting a pulse signal synthesized by the circuit 3 on the basis of the depression signal to the line 4, the controller 1 reports a key scanning code corresponding to the prescribed line 4 to master software, and corresponding application software is started by the master software.
