[0002]

2. Description of the Related Art With the use of various image processing apparatuses in offices and homes, the increase in power consumption of them has become a problem. Therefore, various measures have been taken to reduce the power consumption of these image processing apparatuses.

FIG. 10 shows a conventional image processing device devised to save power. This image processing apparatus is disclosed in Japanese Examined Patent Publication No. 4-37615, and includes two power supply units, a main power supply unit 11 and a sub power supply unit 12. These power supply units 11 and 12 are the power switch 1
It is connected to a commercial power source (not shown) through the line 3.

The main power supply unit 11 is a power supply having a large capacity, and supplies power to each unit 14 in the apparatus and also supplies power to a master CPU (central processing unit) 15. The sub-power supply unit 12 is a power supply unit having a relatively small capacity, and supplies power to the operation display unit 16 provided with keys and a display unit for operating the image processing apparatus and the slave CPU 17. The sub power supply unit 12 is always supplied with power when the power switch 13 is turned on.

The slave CPU 17 detects, for example, when the operator performs a predetermined operation on the operation display unit 16 or when an incoming call is received from a partner station (not shown).
Then, ring (ringing) the attached telephone (not shown)
To output a ringing control signal 21 to activate the start switch control signal 22 to operate the start switch for recording an image, and to activate a copy switch to start copying. 23 for generating a document or inserting a document into a scanner (not shown) for image transmission.
An operation such as outputting 5 is performed. In addition, the slave CPU 17 sends a control start signal 25 to the main power source 11 at a predetermined timing to activate the above-described units 14, and causes the control by this to start up.

FIG. 11 shows a case where the technique disclosed in Japanese Patent Publication No. 4-37615 is applied to an image processing apparatus having a copying function and a facsimile function. This image processing apparatus is provided with two power supply units, a necessary power supply unit 31 corresponding to the output power supply unit 11 shown in FIG. 10 and a constant power supply power supply 32 corresponding to the sub power supply unit 12. Is supplied with power from a commercial power supply (not shown) via the power switch 33.
The power-on-demand unit 31 is composed of a relatively large-capacity power supply, and supplies power to each unit 34 such as an exposure lamp and a power supply for fixing in the image processing apparatus when they are needed, while controlling a copying function. Power is also supplied to the copy function control section 35 as a circuit section for the time period required by them.

The power supply 32 for the always-energizing part is a power supply having a relatively small capacity, and supplies power to the operation display section 36 and the first communication control section 37A in the communication control section 37. The power is constantly supplied to the operation display unit 36 so that the operation of the operator can be dealt with at any time. The reason why the power is always supplied to the first communication control section 37A is that the incoming call can be dealt with at any time. The communication control unit 37 includes a first communication control unit 37A and a second communication control unit 37B as a circuit unit that can be dealt with by subsequent power supply. The first communication control part 37A includes a power supply part 31 when needed.
At the stage where the power supply of 1 is required, the control start signal 39 is sent to this so as to enable the power supply to the main part later.

[0008]

As described above, the image processing apparatus shown in FIG. 11 is provided with one power supply 32 for the always-energizing part, and the operation display section 36 and the first communication control section 37A.
Power is supplied to both of them from the same location. However, the image processing apparatus having a plurality of functions such as communication and recording or copying as shown in this example is not necessarily commercialized in a form in which these plurality of functions are complete, and some functions are optional. It may be added. Providing an image processing device with only the functions that the user needs and adding options as needed for functions that are needed later is used to prevent unnecessary purchase of functional parts. It is useful to the person.

However, in the conventional image processing apparatus shown in FIG. 11, regardless of whether the communication control section 37 is optionally incorporated in the apparatus or not, the power supply 32 for the always-energized portion is used.
Will be installed in the device. Since the power supply 32 for the always-energized portion will be used as a power supply when the communication control unit 37 is incorporated in the device in the future, its capacity is large enough to supply power to the communication control unit 37. Is set to Therefore, in a state where the communication control unit 37 is not incorporated in the device, the power supply 32 for the always-energized portion becomes larger than that for the operation display unit 36 for single use, resulting in power consumption. There is a problem that not only the size becomes unnecessarily large, but also the cost of the power source increases for a user who does not plan to incorporate the communication control unit 37 into the device in the future.

Therefore, an object of the present invention is an apparatus capable of exhibiting complex functions by adding functional parts, and an image processing apparatus capable of efficiently reducing power consumption even in the state where no functional parts are added. To provide.

The I / O port 148 outputs data or commands to other circuit devices to be controlled other than the operation display unit 117 shown in FIG. 2 or inputs data or commands from these other circuit devices. It is a port for.

The first communication control section 1 shown in FIG.
The 16A and the copy function control section 119 are each provided with their own CPU, and are designed to control their respective circuit parts. Therefore, the display CPU 141 does not finely control the copy function control unit 119 while the first communication control unit 116A is not connected to the image processing apparatus. In addition, the first communication control portion 116A
CPU (communication CPU) provided in the communication device 10
6 is attached to the image processing apparatus, the display CPU 141
Instead of this, the overall control of the image processing apparatus is performed. Whether or not the communication device 106 is attached to the image processing apparatus is initially determined when the power switch 111 is turned on. As a result of this,

FIG. 4 shows an outline of the circuit configuration of the first and second communication control parts. First and second
The communication control parts 116A and 116B of the above are provided with a communication CPU 151 for controlling them and controlling the entire image processing apparatus in a predetermined case. Communication CPU 151
Via bus 152, ROM 153, working memory 1
54, the communication control circuit 155, the timer circuit 156, and the first and second I / O ports 157 and 158. The ROM 153, the work memory 154 and the timer circuit 156 are functionally the same as the corresponding circuits in FIG. Communication control circuit 155
Is connected to the line 161 and is used to transmit / receive facsimile data to / from another facsimile apparatus or computer. First I / O port 15
7 mainly connects the circuit portion which constitutes the second communication control portion 116B to the bus 152. The second I / O port 157 is used for exchanging necessary data with other circuit parts of the image processing apparatus.

FIG. 5 shows a state of control for canceling the power saving of the image processing apparatus to which the communication device is attached. The communication CPU 151 shown in FIG. 4 monitors whether an incoming call for facsimile communication is made via the communication control circuit 155 (step S10).
1). In addition, the operation display unit 1 indicates whether any key or switch of the operation display unit 117 shown in FIG. 2 is operated.
It is monitored by the presence / absence of the operation start signal 131 input from 17 (step S102). When an incoming call for facsimile communication is made (step S101; Y),
The communication CPU 151 performs facsimile data reception processing according to the procedure written in the ROM 153 (step S103). Then, a relay excitation signal is generated at a predetermined timing of this processing (step S104). This relay excitation signal is substantially the same signal as the first operation instruction signal 131 shown in FIG. This relay excitation signal is input to an excitation control circuit (not shown), and the power supply relay 114 shown in FIG. 2 is excited.

When the power supply relay 114 is excited, the power supply section 118 for the energizing section is activated when necessary, and the copy function control section 1
The power supply to 19 and the second communication control section 116B and each unit 121 in the apparatus starts. As a result, the image data sent from the other party of communication is recorded.

On the other hand, if any key or switch of the operation display unit 117 is operated before the arrival of the facsimile (step S102; Y), a relay excitation signal is immediately generated in this case (step S10).
4). This is because there is a possibility that an operation for immediately starting the reading of the image for copying or the recording of the read image is performed. The relay excitation signal at this time is substantially the same signal as the second operation instruction signal 132 shown in FIG. When the power supply relay 114 is excited, the power supply section 118 for the energizing section is activated as necessary as described above, and the copy function control section 119 and the second communication control section 11 are activated.
Power supply to 6B and each unit 121 in the apparatus starts. Thus, the first and second operation instruction signals 13
Even if the relay excitation signal corresponding to either 1 or 132 is generated, the relay excitation signal is generated in the form of the logical sum of these, and the supply of power to necessary circuit parts is started. Will be.

FIG. 6 shows a state of control for starting power saving of the image processing apparatus to which the communication device is attached. The communication CPU 151 shown in FIG. 4 performs the copying operation using the reading device and the recording device, and the communication device 106.
Then, it is checked whether or not the facsimile reception using the recording device is completed (step S201). Then, when this is completed, the timer circuit 15 shown in FIG.
A timing operation for starting power saving is started for 6 (step S202). This timing operation is continued until the preset time is reached and a time-out is performed unless the timing is canceled midway (step S203) (step S204). Here, the release of the time counting operation is performed by the incoming call of the facsimile in step S101 shown in FIG. 5 or the operation of the operation display unit 117 in step S102. Once the time counting operation is released, the process returns to step S201, and the time counting operation by the timer circuit 156 is not started until the copying operation or the communication operation ends. Also,
When the time counting operation is released in step S203, the time counting of the timer circuit 156 is reset, so the time counting operation is started again from the beginning.

When the timer circuit 156 times out (step S204; Y), the communication CPU 151 sends a relay demagnetization signal from the second I / O port 158 to the above-mentioned excitation control circuit (step S205), and the power supply relay. The excitation of 114 (FIG. 2) will be released. As a result, power supply to the second communication control section 116B and the copy function control section 119 shown in FIG. 2 is stopped.

FIG. 7 shows the principle configuration of the circuit configuration of the image processing apparatus of this embodiment when no communication device is attached, and corresponds to FIG. Since it has been described with reference to FIG. 2, detailed description of the circuit is omitted. Since the communication device 106 shown in FIG. 1 is not attached to the image processing device, the operation display unit 1 is always energized.
17, the operation display power supply unit 113 supplies this power. The copying function control unit 119 is supplied with power only from the power supply unit 118 for the energized portion when necessary, at a necessary time.

FIG. 8 shows a state of control for canceling the power saving of the image processing apparatus when the communication apparatus is not attached. Display CPU 1 shown in FIG.
41 is an operation display unit 117 via the display control circuit 146.
It is monitored whether any one of the keys or switches has been operated (step S301). And the operation display unit 1
When any key or switch of 17 is operated (Y), a relay excitation signal is generated (step S302). As a result, as described above, the power supply unit 118 for the energized portion is activated when necessary, and the power supply to the copy function control unit 119 is started.

FIG. 9 shows a state of control for starting power saving of the image processing apparatus when the communication apparatus is not attached. Display CPU shown in FIG.
141 checks whether or not the copying operation using the reading device or the recording device is completed (step S40).
1). Then, when this is finished, the timer circuit 147 shown in FIG. 3 is caused to start the time counting operation for starting the power saving (step S402). This timing operation is performed unless the timing is canceled during the operation (step S40).
3) The process continues until the preset time is reached and the time-out is performed (step S404). Here, the release of the timing operation is performed by operating the operation display unit 117 in step S102 shown in FIG. Once the time counting operation is canceled, the process returns to step S401, and the time counting operation by the timer circuit 147 is not started until the copying operation ends. When the time counting operation is canceled in step S403, the time counting of the timer circuit 147 is reset, so that the time counting operation is started again from the beginning.

When the timer circuit 147 times out (step S404; Y), the display CPU 141 sends a relay demagnetization signal from the I / O port 148 to the excitation control circuit (step S405), and the power supply relay 11
4 (FIG. 2) will be released. As a result, the power supply to the copy function controller 119 shown in FIG. 2 is stopped.

In the above-described embodiment, any key or switch is operated as a condition for operating the power supply section 118 for the necessary energizing section by operating the operation display section 117. When necessary, the power supply unit 118 for the energized portion is provided on condition that a key or switch having a specific function necessary to start energization such as copying starts.
May be activated. In addition, the operation display unit 11
In accordance with the operation content of 7, for example, the second communication control part 11
Immediately energize only 6B, copy function control unit 119
It is also possible to perform control such that the power is turned on after a delay of a predetermined time from the operation of the operation display unit 117.

Further, in the present embodiment, for example, the copying function control section 119 is energized all together when there is a facsimile incoming call, but when there is a facsimile incoming call and image information is recorded based on this, it is read. Since the operation of the apparatus is unnecessary, it is possible to control the energization of only the recording apparatus to further save power.
Similarly, when the operator operates the operation display unit 117 in order to copy only the image information once stored in the image processing apparatus, by analyzing the operation content, for example, only the recording apparatus is energized. It is also possible to save power by deciding to operate.

[0041]

As described above, according to the first aspect of the present invention, the always energizing portion is separated for the communication means detachably attached to the device and the operation control means originally provided in the device. By making the part to be energized integral with the communication means and attachable to and detachable from the image processing apparatus, it is possible to further reduce the size of the image processing apparatus without the communication means and reduce the cost.

Further, in the invention according to claim 4 , since the communication control section is divided into the first communication control section which is constantly supplied with power and the second communication control section which is supplied with electricity when necessary, large power is required for transmission. In the case of such a device, there is an effect that the power saving effect can be particularly increased.
