The present invention provides a facsimile receiver in which a second power supply circuit is provided separately from the first power supply circuit that continuously supplies power, and the magnetic disk is supplied with power from the second power supply circuit during device operation. This reduces power consumption when the device is on standby.

[Conventional technology]

A facsimile receiver that temporarily stores received messages is
It is widely used because it allows messages to be received without depending on the amount of recording paper remaining even when the system is operated unmanned, such as at night.

As a means for storing this message, it is common to use a semiconductor memory element or a magnetic disk.

Traditionally, facsimile receivers using magnetic disks
The configuration was as shown in Figure 2.

In FIG. 2, reference numeral 1 denotes a communication control unit that controls the reception of messages from the destination facsimile, storage and recording of the messages;
Reference numeral 2 denotes a magnetic disk for temporarily storing received telegrams, 4 a call detection circuit for detecting a call signal from an exchange, and 9 a recording section for outputting the received telegrams as images on recording paper. Also,
Reference numeral 7 denotes a power supply circuit that supplies power to the communication control section 1, the call detection circuit 4, the magnetic disk 2, and the recording section 9.

Here, when the call detection circuit 4 detects a call signal from the exchange, it provides the result to the communication control section 1.

The communication control unit 1 monitors the detection output of the call detection circuit 4 and starts receiving the message when the detection output is input. When a message is sent from a destination facsimile machine not shown in FIG. 2, this received message is temporarily stored on the magnetic disk 2. When the reception of the received telegram is completed and there is any recording paper left in the recording section 9, the communication control section 1 reads out the received telegram stored on the magnetic disk 2 and provides it to the recording section 9. As a result, the received telegram is recorded and output.

On the other hand, if there is no recording paper left in the recording section 9, the communication control section 1 does not start recording until the recording paper is replenished by the operator.

[Problem that the invention seeks to solve]

However, with such conventional facsimile receivers,
In order to temporarily store the received message on the magnetic disk 2, it is necessary to keep the magnetic disk 2, which takes a certain amount of time after startup, in an operational state at all times, and for this reason, the disadvantage is that power must be constantly supplied. was there.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned drawbacks, and aims to provide a facsimile receiver that consumes less power when the device is on standby.

A magnetic disk 2 for storing the received message, a recording section 9 for recording the received message on paper, a means for receiving the received message from the other party, a means for storing the received message on the magnetic disk 2, and a means for storing the received message on the magnetic disk 2. The received message is recorded in the recording section 9.
The communication controller 1 includes a communication control unit 1 including means for providing power to the call detection circuit 4, and a first power supply circuit 7 that continuously supplies power to the call detection circuit 4.

Here, the present invention is characterized by comprising a control circuit 5 connected to the power supply circuit 7 and a semiconductor memory circuit 3 for storing the received message from the communication control unit l, and separately from the power supply circuit 7, the communication control circuit 5 is connected to the power supply circuit 7. A power supply circuit 6 is provided to supply power to the storage section 1, the recording section 9, the magnetic disk 2, and the semiconductor storage circuit 3. The control circuit 5 includes means for supplying power to the power supply circuit 6 based on the detection output of the call detection circuit 4 and stopping the recording section 9 after recording the received message. be.

The operation of the facsimile receiver having such a configuration will be explained. In FIG. 1, a power supply circuit 7 continuously supplies power to a call detection circuit 4 and a control circuit 5. In FIG. The power supply circuit 6 has its power supply controlled by the control circuit 5, and supplies its output to the communication control section 1, the magnetic disk 2, the semiconductor storage circuit 3, and the recording section 9.

When the device is in a standby state, the control circuit 5 turns off the output of the power supply circuit 6. The call detection circuit 4 constantly monitors the state of the input terminal 10 and detects a call signal from the exchange. The control circuit 5 detects a call signal from the exchange by monitoring the output of the call detection circuit 4. When the call detection circuit 4 detects a call signal from the exchange, the control circuit 5 turns on the output of the power supply circuit 6.

When the output of the power supply circuit 6 is turned on, the communication control section 1 starts communication with the destination facsimile machine. On the other hand, magnetic disk 2
starts up as soon as power is supplied, but it takes some time before it becomes operational. This time is about 15 seconds to 20 seconds. The communication control unit 1 starts receiving messages from the destination facsimile before the magnetic disk 2 becomes operational, and temporarily stores the received messages in the semiconductor storage circuit 3.

When the magnetic disk 2 becomes operational, the communication control unit 1
reads the received message temporarily stored in the semiconductor storage circuit 3 and stores it in the magnetic disk 2. Subsequent received messages are also temporarily stored in the semiconductor memory circuit 3, and the contents of the semiconductor memory circuit 3 are read out and written to the magnetic disk 2.

When the message reception is completed, the communication control unit 1 transfers the magnetic disk 2
The received telegram stored in is read out and recorded and output from the recording section 9. After the recording output is completed, the control circuit 5 turns off the output of the power supply circuit 6.

〔Effect of the invention〕

As described above, the present invention can turn off the power to the magnetic disk when the apparatus is on standby, and has the excellent effect of reducing the power consumption of the apparatus.

Another advantage is that the message can be received before the magnetic disk becomes operational.
