Patent JP-H04193038-A (JP)
Title: Charger
Inventor: NAKAJIMA TAKASHI
IPC: H02J7/10
Filed: 1990-11-26
Abstract: PURPOSE:To realize proper charging by providing an oscillation means for switching the oscillation frequency according to the operating state of a machine, and means for switching the charging current of a battery according to the operating state of the machine and interrupting the charging current when the count in means for counting the output pulse from the oscillation means reaches a predetermined count. CONSTITUTION:A charging current control means 4 switches the charging current between I1 and I2 according to whether a word processor 5 is operating or not. Charging operation of an Ni-Cd battery 6 is terminated by counting the input pulses fed from a counting means 8 by predetermined numbers. An oscillation frequency selecting means 9 selects oscillation means 10 or 11 depending on whether the word processor 5 is operating or not based on an input signal to the counting means 8. Since the oscillation frequencies f10, f11 of the oscillation means 10, 11 are set such that f10<f11, charging time is longer when the word processor 5 is operating as compared with the core that the processor is not operating.
