Power control apparatus of public telecommunication terminal
First Claim
1. A power control apparatus of a public telecommunication terminal, said apparatus comprising:
- a power control unit adapted for supplying holding power and operating power;
a central control unit operated with said operating power supplied from said power control unit to thereby control a public communication function and for storing an information set on a power control program by which said power control unit is turned on or off; and
an auxiliary control unit operated with said holding power supplied from said power control unit and for downloading the information set on said power control program stored in said central control unit by which said power control unit is turned on or off, wherein said auxiliary control unit compares a current time with a starting time among said information set in said power control program and if said current time corresponds to said starting time, turns said power control unit on such that said operating power is supplied to said central control unit;
said central control unit controls said power control unit if said current time corresponds to an ending time among said information set on said power control program such that said power control unit is in a standby state and at the same time, completes the operation itself; and
said power control unit is turned on under the control of said auxiliary control unit to thereby supply said operating power to said central control unit or is turned off under the control of said central control unit to thereby cut off the supply of said operating power to said central control unit such that the operation of said central control unit is completed.

Abstract
Disclosed is a power control apparatus of a public telecommunication terminal which makes the public telecommunication terminal (e.g., a public telephone) disposed in every place provided with a power control program so that the public telecommunication terminal itself can turn on/off the power supplied thereto in an automatic way. The apparatus includes: a power control unit supplying holding power and operating power; a central control unit operated with the operating power supplied from the power control unit to thereby control a public communication function and for storing the information set on a power control program with which the power control unit is turned on or off; and an auxiliary control unit operated with the holding power supplied from the power control unit and for downloading the information set on the power control program stored in the central control unit with which the power control unit is turned on or off, wherein the auxiliary control unit compares current time with starting time among the information set in the power control program and if the current time corresponds to the starting time, turns the power control unit on such that the operating power is supplied to the central control unit; the central control unit controls the power control unit if the current time corresponds to ending time among the information set on the power control program such that the power control unit is in a standby state and at the same time, completes the operation itself; and the power control unit is turned on under the control of the auxiliary control unit to thereby supply the operating power to the central control unit or is turned off under the control of the central control unit to thereby cut off the supply of the operating power to the central control unit such that the operation of the central control unit is completed.
