Embodiment 1

[0035] see image 3 with Figure 4 , image 3 It is a circuit structure diagram (standby state) of the zero-power standby automatic starting device of the facsimile machine in Embodiment 1 of the present invention; Figure 4 for image 3 The actual wiring diagram inside the relay.

[0036] The structure of the action circuit 10 is as follows: a rectifier D1 is connected to the outside lines d1 and d2 of the telephone, and the output of the rectifier D1 is connected to an action winding RE1 of the relay RE (hereinafter referred to as the action winding RE1), a regulator tube D5 and the first group of the relay RE. A series circuit composed of normally closed contacts J1-A and J1-B in the switching contacts.

[0037] The structure of the return circuit 20 is: its input terminal is connected to the normally open contacts J1-A and J1-C in the first group of switching contacts of the relay RE, the normally open contacts J1-C and a delay circuit (about 10 seconds ) connection, ...

Embodiment 2

[0049] see Figure 5 , Figure 5 It is a circuit diagram of a zero-power standby automatic starting device for a facsimile machine according to Embodiment 2 of the present invention.

[0050] (1) Standby state

[0051] The thyristor SCR is in cut-off state because there is no trigger voltage, the relay J loses its magnetism, its contact J-1 opens, and the AC power supply circuit of the fax machine is cut off. At this time, the transistors BG1, BG2, and BG3 are all in the cut-off state.

[0052] (2) Ringing start

[0053] When a call comes in, the bell current is coupled through the transformer to generate a trigger signal to turn on the thyristor SCR. Transistor BG1 is turned on due to obtaining collector voltage and injecting base current through R6. The relay J is energized, its contact J-1 is closed, and the facsimile machine is connected to the AC power supply and starts to work.

[0054] (3) Working status

[0055] After the bell disappears, although the thyristor ...

Abstract

The invention discloses a fax machine energy conservation starting method and a device. The method comprises the following steps: a fax machine loop which is arranged between an alternating current power supply and a fax machine is used for controlling the connection and disconnection of the alternating current power supply and the fax machine; an action loop which is connected with an outside line, is in cut-off state in the case of no telephone ringing signal and acts when receiving the telephone ringing signal is used for controlling the fax machine loop so as to lead the alternating current power supply to be connected with the fax machine; and a resetting loop which is coupled with the action loop is used for resetting the action loop to the cut-off state when the fax machine finishesreceiving so as to disconnect the connection of the alternating current power supply and the fax machine. The device of the invention automatically starts the fax machine when a fax signal comes, andcloses the fax machine automatically after receiving the fax signal, thus realizing the function of standby zero power consumption of the fax machine.

Description

technical field [0001] The invention belongs to the field of electricity, and in particular relates to an energy-saving start-up method and device for a facsimile machine, and more specifically relates to a device for controlling the zero-power consumption standby and automatic start-up of a facsimile machine. Background technique [0002] With the wide application of automated office equipment, fax machines have become an indispensable basic office supplies for enterprises and institutions, and they are entering the families of ordinary people with a growing trend. [0003] Compared with other office supplies and household appliances, the hourly usage rate of fax machines is undoubtedly the lowest among all electrical products. In other words, the facsimile machine is in the so-called "standby" state most of the time. The average standby power consumption of a fax machine is 7.5 watts, which consumes 65 degrees of electricity per year. There are tens of thousands of fax m...
