Abstract

PROBLEM TO BE SOLVED: To shorten the time needed for charging a battery pack by preparing the power supply terminals and switches to perform direct supply of power to a communication circuit from a charging device. SOLUTION: When the bottom part of a communication device 55 with a battery pack 58 is put into a charging slot 51a of a charger 51, a battery pack charging power supply terminal 58b is connected to a power supply terminal 61. Then the charger 51 starts to charge the pack 58. At the same time, the power can be supplied to the device 55 from a power circuit 53 when a contact is secured between the device power supply terminal 55a and a charger power supply terminal 62. Under such conditions, the pack 58 is separated from the device 55 and connected to the charger 51 only and the charging current is supplied 100% to the pack 58 from the charger 51 when the 1st and 2nd switch means 56 and 57 of the device 55 are turned off and on respectively. As a result, the charging time of the charger 51 is never increased even the device 55 is kept in its waiting state.
