MOBILE COMMUNICATION TERMINAL DEVICE

摘要

PROBLEM TO BE SOLVED: To prolong the life of a battery by suppressing an increase in power consumption as much as possible. SOLUTION: An electrification control part 7 with an electrification control table is provided and ON/OFF states of electrification to respective circuit parts are stored corresponding to all the operation modes that the device has. When an operation mode is reported by a main control circuit 11 prior to operation, the output Vcc of a power circuit 6 is supplied to only irreducible circuit parts needed to implement the operation mode according to the operation mode and the storage contents of the electrification control table 7 and the electrification to other circuit parts is cut off or reduced.
