BACKGROUND OF THE INVENTION
  The present inventionEnergy saving control device for image recording means and image recording device using the same,Facsimile machine, Printers, copiers and composite devicesIn detail, the recording means connected to the external device and can also be used as a printer by a control signal such as a centro signal from the external device and energy savingControl meansWithDressRelated to the position.
[0002]
[Prior art]
  Recently, energy saving (energy saving) has been demanded, and the facsimile machine also reduces the power consumption by turning off the power consuming part such as the heating part of the recording unit during reception standby etc. The device has appeared.
[0003]
  In the conventional facsimile apparatus that performs energy saving, when the operator enters the energy saving mode, the operator performs the energy saving mode canceling operation with the operation unit, thereby canceling the energy saving mode and turning on the power of each unit.
[0004]
  Conventionally, there has been proposed a facsimile machine that cancels the energy saving mode and turns on the power of each part when a call signal from a telephone line is detected (see Japanese Patent Laid-Open No. 9-95463).
[0005]
[Problems to be solved by the invention]
  However, in such a conventional facsimile apparatus, the energy saving mode is canceled by the energy saving mode canceling operation of the operation unit or the call signal from the line. There was a problem of being bad.
[0006]
  That is, recently, facsimile machines have become highly functional, and accordingly, the performance of the recording unit has been improved, networked, and connected to external devices such as word processors and personal computers. It is used as a printer.
[0007]
  In such a situation where the facsimile apparatus is connected to an external device and used as a printer of the external device, the energy saving mode is canceled by an energy saving mode canceling operation of the operation unit or a call signal from the line as in the conventional facsimile apparatus. In order to use the facsimile apparatus in the energy saving mode from an external device only by canceling the power saving, it is necessary to perform the energy saving cancellation operation by the operation unit of the facsimile apparatus, and there is a problem that the usability of the facsimile apparatus is poor.
[0008]
  Further, for energy saving, conventionally, in a facsimile apparatus, a printer, and the like, since only a power source of a portion that consumes high power such as a heating portion is turned off, further reduction of power consumption is demanded.

In the ROM, a basic program as the facsimile machine 1 and an energy saving control processing program to be described later are provided. Etc. are stored. The system control unit 5 controls each unit of the facsimile machine 1 according to the program in the ROM, executes a sequence as the facsimile machine 1 and executes an energy saving process described later. That is, the system control unit 5 enters the energy saving mode at a predetermined standby time, for example, at the time of reception standby, turns off the power supply other than the energy saving control unit 13, and in this energy saving mode, the signal from the energy saving control unit 13 By the key operation of the energy saving cancel key of the operation display unit 3, the energy saving mode is canceled and the power of each part of the facsimile machine 1 is turned on.
[0037]
  The modem 6 operates under the control of the system control unit 5 to modulate the transmission signal and demodulate the reception signal, and the communication control unit 7 exchanges a facsimile control signal with the counterpart facsimile apparatus to perform facsimile communication. Perform the procedure.
[0038]
  The network control unit 8 is connected to a handset 9 and a line L, for example, a general public line. The network control unit 8 switches between the handset 9 and the line L, and makes a call with the other party by the handset 9. And automatically makes an incoming call for a call from the line L, and performs an automatic call process to the line L.
[0039]
  The plotter control unit 10 controls the operation of the plotter 11 under the control of the system control unit 5, and in particular, selects and generates control signals for facsimile data and external printers.
[0040]
  As the plotter (recording means) 11, for example, an electrophotographic recording apparatus is used. The plotter 11 records and outputs received image data and image data read by the scanner 2 on a recording sheet with a predetermined resolution. Based on the Centro signal, the printer of the external device 22 records and outputs the data transmitted from the external device 22 on recording paper.
[0041]
  The printer I / F 12 receives a print signal from the external device 22 via the energy saving control unit 13, transmits a signal notifying the external device 22 of the state of the facsimile apparatus 1, and also uses the external device together with the system control unit 5. The print signal from 22 is converted into image data. As the printer I / F 12, for example, bidirectional Centronics is used.
[0042]
  As shown in FIG. 2, the energy saving control unit (energy saving control means) 13 includes a multiplexer (MPX) 20, a data decoder / generator 21, a pull-down resistor Rp, and the like. The external device 22, for example, an information device such as a word processor or a personal computer, is connected by a signal line of, for example, a Centronics standard signal line, and the energy saving control unit 13 transmits a signal between the system control unit 5 and the external device 22. Give and receive energy-saving control processing.
[0043]
  That is, in the energy-saving control unit 13, the multiplexer 20 receives various control signals such as the strobe signal STB and the wake-up signal UW and the communication signal 1 such as print data (print data) from the external device 22, and the received communication signal 1 Are distributed to the printer I / F 12 and the data decoder / generator 21 and output as the communication signal 2 and the communication signal 3. The data decoder / generator 21 determines the strobe signal STB and the wake-up command from the communication signal 3 input from the multiplexer 20, and, in the energy saving mode, the busy signal BUSY and notification data indicating that energy saving is in progress. Are output to the multiplexer 20 and a wake-up signal UW for canceling the energy saving mode and turning on the power of each unit of the facsimile apparatus 1 is output to the system control unit 5. The system control unit 5 outputs to the multiplexer 20 a switching signal SW that becomes high (H) in the normal mode that is not the energy saving mode and becomes low (L) by the pull-down resistor Rp in the energy saving mode. Then, the multiplexer 20 determines whether the switching signal SW is high or low, that is, whether the normal mode or the energy saving mode, the signal path to the external device 22 from the printer I / F 12 and the data decoder. In the normal mode, the external device 22 and the printer I / F 12 are connected. In the energy saving mode, the external device 22 and the data decoder / generator 21 are connected.
[0044]
  Next, the operation of the present embodiment will be described. The facsimile apparatus 1 is connected to an external device 22, and the plotter 11 can be used as a printer for the external device 22, and the power supply other than the energy saving control unit 13 is turned off at a predetermined time such as waiting for reception. When a print request such as a strobe signal STB or a wake-up command is received from 22, each part is turned on, and when the power is turned on and a stable state is reached, a signal to that effect is sent to the external device 22. There is its feature.
[0045]
  Hereinafter, this energy saving control process will be described with reference to FIGS. 3 and 4. First, when a strobe signal STB and dummy print data are transmitted from the external device 22, an energy-saving control process (print request acceptance process) for outputting the busy signal BUSY to the external device 22 until the power is turned on and stabilized. Will be described with reference to FIG.
[0046]
  The facsimile apparatus 1 enters an energy saving mode in which the main parts other than the energy saving control part 13 are turned off at a predetermined time such as waiting for reception to save power consumption.
[0047]
  In the normal mode, the system control unit 5 outputs a high switching signal SW to the multiplexer 20 of the energy saving control unit 13 in the normal mode, and the multiplexer 20 communicates the communication signal 1 from the external device 22. If the strobe signal STB and print data which are print requests are output from the external device 22 to the printer I / F 12 as the signal 2, the print data sent from the external device 22 in response to the print request is sent to the system control unit. 5 and the printer I / F 12 are converted into image data, transferred to the plotter control unit 10, and recorded on the recording paper by the plotter 11.
[0048]
  When the energy saving mode is entered from the normal mode, the system control unit 5 sets the switching signal SW output to the system control unit 13 to low, and the multiplexer 20 inputs from the external device 22 when the switching signal SW becomes low. The communication signal 1 is output to the data decoder / generator 21 as the communication signal 3.
[0049]
  In this energy saving mode, the energy saving control unit 13 is in a state in which a command from the external device 22 can be accepted at any time with the busy signal BUSY turned off, that is, in a ready (READY) state. In this state, as shown in FIG. 3, when the strobe signal STB and the dummy print data are transmitted from the external device 22 and the strobe signal STB is turned on (step S1), the energy saving control unit 13 receives the data decoder / The generator 21 determines the on strobe signal STB, turns on the busy signal BUSY, that is, sets the busy (BUSY) state (step S2), and turns on the power of each part of the facsimile apparatus 1 (step S3). That is, the energy saving control unit 13 outputs a wake-up signal UW to the system control unit 5 and causes the system control unit 5 to turn on the power of each unit of the facsimile apparatus 1. When the external device 22 makes a print request to the facsimile apparatus 1, dummy data is written (dummy write) as the first data.
[0050]
  Thereafter, the energy-saving control unit 13 checks whether the initialization (system initialization) of the facsimile apparatus 1 is completed (step S4), and when the initialization is not completed, waits for the initialization to be completed, The busy signal BUSY is turned off, that is, in a ready (READY) state, print data is received from the external device 22, and recording output by the print data is performed in the same manner as in the normal state (step S6).
[0051]
  Therefore, for the external device 22 that uses the plotter 11 of the facsimile apparatus 1 as a printer, the facsimile apparatus 1 is switched to the normal mode and the busy signal BUSY from the facsimile apparatus 1 even when the facsimile apparatus 1 is in the energy saving mode. Thus, it is possible to recognize that the facsimile apparatus 1 has been stably prepared for recording, and even in the energy saving mode, the facsimile apparatus 1 can appropriately perform recording output without impairing operability. be able to. As a result, the usability of the facsimile machine 1 can be improved. In this energy saving mode, the facsimile apparatus 1 can supply power to the energy-saving control unit 13 and can turn off the power supply to the other units, thereby greatly reducing power consumption.
[0052]
  Next, when a wake-up signal is transmitted from the external device 22, energy saving control processing (print request acceptance processing) for outputting notification data indicating that energy is being saved to the external device 22 until the power is turned on and stabilized. Will be described with reference to FIG.
[0053]
  In the normal mode, the system control unit 5 outputs a high switching signal SW to the multiplexer 20 of the energy saving control unit 13 as shown in FIG. When the signal 1 is output to the printer I / F 12 as the communication signal 2 and the strobe signal and the wake-up command are input from the external device 22 as a print request, the print sent from the external device 22 in response to the print request The data is transferred to the plotter control unit 10 and recorded on the recording paper by the plotter 11.
[0054]
  When the energy saving mode is entered from the normal mode, the system control unit 5 sets the switching signal SW output to the system control unit 13 to low, and the multiplexer 20 inputs from the external device 22 when the switching signal SW becomes low. The communication signal 1 is output to the data decoder / generator 21 as the communication signal 3.
[0055]
  In this energy saving mode, the energy saving control unit 13 is in a state in which a command from the external device 22 can be accepted at any time with the busy signal BUSY turned off, that is, in a ready (READY) state. In this state, as shown in FIG. 4, when a strobe signal and a wakeup command are input as a print request (step P1), the energy saving control unit 13 recognizes the wakeup command by the data decoder / generator 21, Notification data indicating that energy is being saved is output to the external device 22 via the multiplexer 20 (step P2), and the power of each part of the facsimile apparatus 1 is turned on (step P3). That is, the energy saving control unit 13 outputs a wake-up signal UW to the system control unit 5 and causes the system control unit 5 to turn on the power of each unit of the facsimile apparatus 1.
[0056]
  Thereafter, the energy saving control unit 13 checks whether the initialization (system initialization) of the facsimile apparatus 1 has been completed (step P4), and if the initialization has not been completed, checks whether a wake-up command has been input ( Step P5).
[0057]
  If there is no wake-up command in step P5, the process returns to step P4 to check that the system has been initialized (step P4). If the initialization has not been completed, the wake-up command is input as described above. Is checked (step P5). When a wakeup command is input in step P5 during the transition from the energy saving mode to the normal mode, data indicating that the energy is being saved is output to the external device 22 that has transmitted the wakeup command (step P6). ), The process returns to step P4 to check whether the initialization of the system is completed (step P4).
[0058]
  In step P5, it is checked whether the wake-up command has been input because the external device 22 that has sent the wake-up command when the wake-up command is input during the transition from the energy saving mode to the normal mode. This is to appropriately notify that the system is in the energy saving mode and waits until the initialization of the system is completed.
[0059]
  When the initialization of the system is completed in step P4, the energy saving control unit 13 transmits a ready command to the external device 22 (step P7), receives print data from the external device 22, and, similarly to the normal state, Recording output by print data is performed (step P8).
[0060]
  Accordingly, when the external device 22 transmits a wake-up command as a print request in the energy saving mode in which the power other than the energy saving control unit 13 that recognizes the print request from the external device 22 is turned off to reduce power consumption, When the control unit 13 turns on the power of each part of the facsimile apparatus 1 and recognizes the wake-up command from the external device 22 and reaches a predetermined stable state, it can output a ready command to the external device 22 and save energy. Even in the mode, it is possible to cancel the energy saving mode in response to a print request from the external device 22 and to perform printing while ensuring reliability in data communication by a ready command. Therefore, power consumption can be greatly reduced, and usability of the external device 22 as a recording unit can be further improved.
[0061]
  The invention made by the present inventor has been specifically described based on the preferred embodiments. However, the present invention is not limited to the above, and various modifications can be made without departing from the scope of the invention. Needless to say.
[0062]
  For example, in FIG. 4 described above, when the data decoder / generator 21 of the energy saving control unit 13 recognizes the wake-up command, the energy saving mode is shifted to the normal mode. When the strobe signal transmitted together with the wakeup command is recognized and the mode is changed from the energy saving mode to the normal mode, the wakeup command is recognized by the system control unit 5, and when the stable state is reached, the ready command is transmitted. Also good. In this way, the data decoder / generator 21 can have a simple structure, and it is not necessary to supply power to the portion for recognizing the wake-up command in the energy saving mode, thereby further reducing power consumption. can do.
[0063]
  In the above embodiment, the case where the present invention is applied to a facsimile apparatus has been described. However, the present invention is not limited to a facsimile apparatus. It can be similarly applied to.
