Title:
TELEPHONE SET
Document Type and Number:
Japanese Patent JP3793298
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To execute speech operation without being limited by an operating time similarly to a usual state even after power failure.
SOLUTION: When an SP key 35 is operated while power from a commercial power supply is interrupted, a feeding state generating circuit 3 generates a feeding state from a subscriber line and power is supplied to a microcomputer 1 by a subscriber power supply section 4 via the feeding state generating circuit 3 to allow the microcomputer 1 to be operated from power from the subscriber line. Thus, the telephone set is realized in which the speech operation is executed whose operating time is not limited similarly to a conventional telephone set even after the power failure.
