<p>PURPOSE:To provide the power supply circuit and control system for surely activating a mouse by fastening the starting time of a mouse power source and sufficiently providing time difference between the starting time of the mouse power source and the starting time of a mouse reset signal. CONSTITUTION:This system is provided with a mouse power source 4 connected to a main body power source 3 and an electrolytic capacitor C1 connected to the mouse power source 4 and composed of a CPU 1 for outputting the pulse of a 300ms width by pulling out a mouse reset signals between the mouse power source 4 and the electrolytic capacitor C1 and detecting the start of voltage of the main body power source 3, and transistor 2 connecting a collector C to the inputs of the main body power source 3 and the mouse power source 4, connecting a base B to the output of the CPU 1 and grounding an emitter E. Thus, the mouse power source 4 is sharply activated after 300ms.</p> |
