DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing a schematic configuration of a facsimile apparatus 16 according to an embodiment of the present invention.

In FIG. 1, a display unit 1 displays the status of the apparatus, time information, and the like under the control of a control unit 4. The ROM 2 stores programs and operator messages for the control unit 4 to control the present apparatus, and the RAM 3 stores data and the like that can be set by the operator.

The CPU 4 is a control unit for controlling the entire apparatus, and executes various control operations according to a control program stored in the ROM 2. The operation unit 5 is for operating the communication terminal device and inputting various kinds of information, and includes a plurality of key input switches, an operation circuit for the key input switches, and the like. The copy key 6 is one key switch in the operation unit 5 and is a key for instructing a copy operation.

The communication section 7 is composed of a hardware circuit or the like for controlling image data and the like into a communication format and for connecting to a communication line 17. The low-power-consumption control unit 8 controls the stop of the oscillation circuit, the stop of the power supply, and the like, and the release from the low power consumption state, in order to reduce the power consumption of the device.

The recording control section 9 interfaces with the recording section 13. The reading unit 10 reads a document, and the document detecting unit 11 detects whether or not there is a document to be read in the reading unit 10.

The system section 12 includes the components from the display section 1 to the document detecting section 11 and performs control other than the recording operation. The recording unit 13 is a recording unit that records image data.

The power supply unit 14 includes the system unit 12 and the recording unit 1
3 is a power supply unit for supplying power to the power supply 3. Switch (SW1)
Numeral 15 is for interrupting the power to the recording unit 13 in the low power consumption state. That is, in this embodiment, the system unit including the control unit 4 for controlling the entire facsimile apparatus by the switch 15 and the recording unit 1 for executing the recording operation
3 have separate power supply sources.

FIG. 2 is a flowchart showing the operation of the facsimile apparatus of this embodiment.

In step S101, the document detection unit 11 detects the presence or absence of a read document. If there is no document, the above operation is repeated.
To release the low power consumption state on the system unit 12 side, and activate the timer T1 in step S103.

Next, in step S104, when there is a copy operation instruction, in step S105, the low power consumption control unit 8
The switch 15 is turned on to supply power to the recording unit 13, and a copy operation is executed in step S106. After the copy operation is completed, in step S109, the switch 15 is turned off by the low-power-consumption control unit 8, and the process shifts to the low-power-consumption state and ends.

If there is no instruction for the copy operation in step S104, it is confirmed in step S107 whether there is an instruction for the communication operation. In step S107, when there is an instruction for the communication operation, the communication operation is executed in step S108, and after the communication operation is completed, the system unit 12 is shifted to the low power consumption state in step S109, and the processing ends.

If there is no instruction for the communication operation in step S107, it is checked in step S110 whether the timer T1 has timed out. At step S110, the timer T1
Is timed out, a warning is issued to the operator in step S11, and the process ends.

[0023]

As described above, according to the present invention,
When the reading unit detects a read document and shifts to the release of the low power consumption state, power supply to the recording unit is not performed. It is possible to provide an environment-friendly facsimile apparatus that consumes no power.

Further, according to the present invention, when an instruction for a copy operation is detected, the power supply to the recording unit is started, so that it is possible to appropriately cope with the copy operation while suppressing unnecessary power consumption.

According to the present invention, if a copy operation instruction or a communication instruction is not issued within a certain period of time after a reading original is detected by a reading unit, a warning is issued to an operator, thereby wasting power. Consumption can be further suppressed.
