The recording device 12 is composed of an inkjet head, a thermal head, etc. (not shown) and a document conveying system. The CPU 16 outputs a drive and stop signal to the recording device 12 to output a document. It is designed to print.

The NCU 13 is connected to the modem 14 and the attached telephone T, connects the telephone line, and controls the line switching between the facsimile apparatus F and the attached telephone T. The modem 14 also modulates / demodulates a transmission / reception signal. In this embodiment, it is assumed that the line has been switched to the side of the attached telephone T during standby.

As shown in FIG. 1, the power supply circuit 15 is connected to the reading device 11, the recording device 12, the control circuit 10 and the like to supply electric power to various devices. Further, the power supply circuit 15 is connected to a power supply switch 20 provided in the operation section 4 and a reed switch 21. The power switch 20 is composed of a return type push button switch, and is turned off when pressed and turned on when released. Moreover, the reed switch 21 is turned on by the magnetic force of the electromagnetic coil 22 connected to the NCU 13, and is turned off when the magnetic force is released. Then, the power supply circuit 15 is turned on by the power switch 20 being released by pressing the interlock 3a, and is closed to supply power to various devices such as the reading device 11, the recording device 12, and the control circuit 10. There is. Further, the power supply circuit 15 is turned on by closing the reed switch 21 by turning on the reed switch 21 by exciting the electromagnetic coil 22 by the call signal of 16 Hz input to the NCU 13 from the calling side through the exchange and the telephone line. Power is supplied to the device 11, the recording device 12, the control circuit 10, and the like. Further, the power supply circuit 15 is provided with a self-holding circuit 23, and after the power switch 20 and the reed switch 21 are turned on, the closed state of the power supply circuit 15 is held. A communication control power supply circuit 24 is connected to the NCU 13, the modem 14, and the attached telephone T, and is connected to an AC power supply together with the power supply circuit 15 and is always energized.

Next, the operation of the facsimile apparatus F configured as above will be described. When transmitting a document by the facsimile device F, if the cover 3 is opened and locked at the rear surface of the upper case 2b of the main body case 2, the pressing of the power switch 20 by the interlock 3a of the cover 3 is released. When the self-holding circuit 23 is closed and the power supply circuit 15 is closed and energized, the energized state of the control circuit 10, the reading device 11, the recording device 12, etc. is maintained. After that, various circuits including the RAM 18 of the control circuit 10 are initialized. Then, insert the original into the insertion slot 4a, operate the numeric keypad 5 of the operation unit 4 to enter the FAX number, and press the start key 8 to connect the line with the called side by the NCU 13 and set the facsimile line. When switched, the CPU 16 drives the reading device 11 to read the original and transmits the read data via the modem 14 and the NCU 13. When the CPU 16 inputs the transmission end signal from the NCU 13 after reading the original, the timer 19 starts counting down, and the cover 3 is closed within a certain time and the power switch 20 is not turned off by the interlock 3a. The timer 19 counts up, the self-holding circuit 23 is opened, the power supply circuit 15 is de-energized, and the reading device 11, the recording device 12, the control circuit 10 and the like are de-energized.

When the facsimile device F receives transmission data, when a call signal of 16 Hz is input to the NCU 13 from the calling side through the exchange and the telephone line, the weak current of the call signal causes electromagnetic waves to flow. The coil 22 is excited to generate a magnetic force. The reed switch 21 is turned on by this magnetic force, and the self-holding circuit 23 and the power supply circuit 15 are closed and energized. The self-holding circuit 23 turns on the energization state of the reading device 11, the recording device 12, and the control circuit 10. Retained. After that, various circuits including the RAM 18 of the control circuit 10 are initialized, the NCU 13 detects a CNG signal or the like and switches to the facsimile line, and the CPU 16 inputs the received data via the NCU 13 and the modem 14, and the recording device. 12 is driven to record the received data on the recording paper. When the CPU 16 confirms the end of recording the received data and inputs the reception end signal from the NC U13, the energization of the self-holding circuit 23 is released, and the power supply circuit 15 is closed to thereby cause the reading device 11 to record. De-energize the device 12, the control circuit 10 and the like.

When the attached telephone T is used as a calling side, the attached telephone T, the NCU 13, and the modem 14 are always energized via the communication control power supply circuit 24. Therefore, the fax machine F and the attached telephone T The numeric keypad 5, which also serves as the operation of, and the function key 6 are also energized. Therefore, when the cover 3 is open or closed, the NCU 13 inputs a telephone number or the like by operating the numeric keypad 5 or the like, and when it confirms that it is in the on-hook state, the NCU 13 sends a dial pulse or the like through the telephone line. Let me Then, when the line with the other party is connected, a call is started at the attached telephone T via the NCU 13 and the modem 14.

When the auxiliary telephone set T is used as a called side, a call signal of 16 Hz is input to the NCU 13 in the above state, and if a CNG signal or the like is not detected within a certain period of time after that, the call is issued. It is determined that the calling side is a telephone, and a calling voltage is generated to ring the attached telephone T. When the call signal is input, the reed switch 21 is turned on and the self-holding circuit 23 and the power supply circuit 15 are closed. However, when the NC U13 does not detect the CNG signal or the like, the CPU 16 causes the self-holding circuit. By deenergizing 23 and closing the power supply circuit 15, the reading device 11, the recording device 12, the control circuit 10 and the like are deenergized.

As described above, in the facsimile apparatus F of the present embodiment, when the cover 3 is closed, the power switch 20 is pressed by the interlock 3 a to turn off the power switch 20 to open the power circuit 15, so that it is not used. Since power is not supplied to various devices when the cover 3 is closed, which is time, power consumption can be reduced.

Further, when the cover 3 is closed, the power switch 20 is pressed by the interlock 3a to be turned off and the power circuit 15 is opened, so that the reed switch 21 is turned on by the calling signal from the calling side. By operating the power supply circuit 15, the power supply circuit 15 is automatically closed and various devices such as the control circuit 10 are turned on, so that the facsimile can be automatically received.

Further, even when the cover 3 is closed, the numeric keypad 5 and the function key 6 are inserted through the insertion holes 3b of the cover 3 so that the upper portion thereof is projected, and the operation of the attached telephone T is also performed. Since the attached telephone T is always energized through the communication control power supply circuit 24, the attached telephone T can be used at all times.

The present invention is not limited to the above-mentioned embodiment, and may be arbitrarily changed as follows without departing from the spirit of the present invention. In the above-described embodiment, the power switch 20 is adopted, and an interlock 3a as an operating portion is provided at a position of the cover 3 corresponding to the power switch 20 so that the cover 3 is turned on / off by the opening / closing operation. However, the interlock 3a is omitted, and the power switch 20 is provided with a switch piece as an operating part so as to protrude from the operation part 4 of the upper case 2b. When the cover 3 is closed, the switch piece is pressed to perform an off operation and open. At this time, the pressing of the switch piece may be released and the switch may be turned on.
