(Main controller 200)
As shown in FIG. 2, the main controller 200 includes a CPU 204, a RAM 206, a ROM 208, an I / O (input / output unit) 210, and a bus 212 such as a data bus and a control bus for connecting them. A UI touch panel 216 is connected to the I / O 210 via a UI control circuit 214. In addition, a hard disk (HDD) 218 and a power saving button 219 are connected to the I / O 210. The functions of the main controller 200 are realized by the CPU 204 operating based on programs recorded in the ROM 208, the hard disk 218, and the like. Note that the image processing function may be realized by installing the program from a recording medium (CD-ROM, DVD-ROM, etc.) storing the program and operating the CPU 204 based on the program.

  The power saving button 219 is a so-called hard switch (physically operated switch), and each time it is pressed, the device is alternately instructed to save power and cancel power saving. This power saving will be described later.

  The main controller 200 according to the present embodiment instructs the connected device in three types of modes: a standby mode, a power saving mode, and a sleep mode. The standby mode is a power supply state, and the sleep mode is a power cutoff state. The power saving mode is a mode instructing some devices that may require power to reduce the time from job reception to execution start.

  The main controller 200 instructs one of the three types of modes, but a device that does not have the power saving mode may shift to the sleep mode or the standby mode in response to the power saving mode instruction.

  A timer circuit 220 and a communication line I / F 222 are connected to the I / O 210. Further, the I / O 210 is connected to a device selection I / F 234.

  The device selection I / F 234 is connected to each device of the facsimile communication control circuit (modem) 236, the image reading unit 238, and the image forming unit 240. Note that the UI touch panel 216 may be recognized as a device.

  The timer circuit 220 measures the initial set time as an opportunity to put the facsimile communication control circuit 236, the image reading unit 238, and the image forming unit 240 into a power saving state (power supply non-supply state). .

  The main controller 200 and each device (facsimile communication control circuit 236, image reading unit 238, image forming unit 240) are supplied with power from the power supply device 202 (see the chain line in FIG. 2). In FIG. 2, the power supply line is shown by one dotted line, but in reality it is two to three wires. Although not shown, the UI touch panel 216 receives power supply separately from the main controller 200, and receives power supply control or cutoff control from the power supply control circuit 252.

(Power supply device 202)
As shown in FIG. 2, the input power supply line 244 drawn from the commercial power supply 242 is connected to the main switch 246. When the main switch 246 is turned on, power can be supplied to the first power supply unit 248 and the second power supply unit 250.

  The first power supply unit 248 includes a control power generation unit 248A and is connected to the power supply control circuit 252 of the main controller 200. The power supply control circuit 252 supplies power to the main controller 200 and is connected to the I / O 210. According to the control program of the main controller 200, each device (facsimile communication control circuit 236, image reading unit 238, image forming unit 240). Switching control to turn on / off the power supply line to).

  On the other hand, a first sub power switch 256 (hereinafter also referred to as “SW-1”) is interposed in the power line 254 connected to the second power unit 250. This SW-1 is controlled to be turned on / off by the power supply control circuit 252.

  The second power supply unit 250 includes a high voltage power generation unit (mainly for a heater power source used for the fixing unit of the image forming unit 240) 250H and a low voltage power generation unit (LVPS) 250L. The high voltage power generation unit 250H is a power source mainly used in the charging unit, the developing unit, the transfer unit, and the like of the image forming unit 240.

  The high voltage power generation unit 250H and the low voltage power generation unit (LVPS) 250L of the second power supply unit 250 selectively include an image reading function power supply unit 258, an image forming function power supply unit 260, and an image copying function power supply. 262, facsimile reception function power supply unit 264, and facsimile transmission function power supply unit 266.

  In the present embodiment, in addition to the above-described power supply system for each function, the high voltage power generation unit 250H and the low voltage power generation unit (LVPS) 250L of the second power supply unit 250 include an image forming unit dedicated power supply unit. 267 is connected.

  In the image forming unit 240, in the temperature management of the fixing unit, the temperature is lower than the temperature in the standby mode in which the image forming process can be immediately executed, but can be raised to the image forming processable temperature relatively quickly. May be maintained (power saving mode).

  For this reason, during power saving, the power supply is cut off to suppress power consumption as the sleep mode, but the image forming unit 240 temporarily maintains the power saving mode state until the sleep mode is entered, Thereafter, the image forming unit dedicated power supply unit 267 is provided in order to shift to the sleep mode.

  The image reading function power supply unit 258 uses the low voltage power generation unit (LVPS) 250L as an input source, and reads an image via a second sub power switch 268 (hereinafter also referred to as “SW-2”). Connected to the section 238.

  The image forming function power supply unit 260 may be referred to as a third sub power switch 270 (hereinafter “SW-3”) with the high voltage power generation unit 250H and the low voltage power generation unit (LVPS) 250L as input sources. ) To the image forming unit 240.

  The image copying function power supply unit 262 may have a fourth sub power switch 272 (hereinafter referred to as “SW-4”) using the high voltage power generation unit 250H and the low voltage power generation unit (LVPS) 250L as input sources. ) To the image reading unit 238 and the image forming unit 240.

  The facsimile receiving function power supply unit 264 may have a fifth sub power switch 274 (hereinafter referred to as “SW-5”) using the high voltage power generation unit 250H and the low voltage power generation unit (LVPS) 250L as input sources. ) To the facsimile communication control circuit 236 and the image forming unit 240.

  The facsimile transmission function power supply unit 266 uses the low voltage power generation unit (LVPS) 250L as an input source, and performs facsimile communication via a sixth sub power switch 276 (hereinafter also referred to as “SW-6”). It is connected to the control circuit 236 and the image reading unit 238 (excluding output of communication reports and the like).

  The image forming unit dedicated power supply unit 267 may have a seventh sub power switch 277 (hereinafter referred to as “SW-7”) using the high voltage power generation unit 250H and the low voltage power generation unit (LVPS) 250L as input sources. .)) To the image forming unit 240.

  The second sub power switch 268, the third sub power switch 270, the fourth sub power switch 272, the fifth sub power switch 274, the sixth sub power switch 276, and the seventh sub power switch 277 are: Similarly to the first sub power switch 256, on / off control is performed based on a power supply selection signal from the power supply control circuit 252 of the main controller 200.

  In the above configuration, power is supplied to select each device (facsimile communication control circuit 236, image reading unit 238, image forming unit 240) for each function, and power is not supplied to devices unnecessary for the instructed function. Minimal power is required.

  Here, in the present embodiment, in the main controller 200, the power supply control circuit 252 controls on / off of the switches SW-1 to SW-7 to select a device corresponding to each processing function. In addition to supplying power to the minimum necessary devices (standby mode), it is possible to perform so-called “partial power saving” in which power supply to unnecessary devices is cut off (sleep mode).

  For example, since the image forming unit 240 is not applied to the image reading function or the facsimile transmission function (except for the report output), from the viewpoint of “partial power saving”, the image forming unit 240 is a device whose power supply is cut off. However, the image forming unit 240 has a fixing unit that requires temperature control of a heating medium (such as a halogen lamp or a heater), and cannot perform temperature control at all when the supply of power is cut off. Therefore, the image forming unit 240 maintains the temperature of the heating medium of the fixing unit in a “low power” state, which is lower than that in the standby mode (power saving mode).

  FIG. 3 shows the control of the power supply control circuit 252 in the CPU 204 of the main controller 200 while simultaneously performing switching control between the standby mode / sleep mode by “partial power saving” and the power saving mode of the image forming unit 240 and the like. Is a functional block.

  As shown in FIG. 3, the main controller mode selection unit 24 manages the mode instructed to each device (see FIG. 5).

  The main controller mode selection unit 24 is connected to the job reception unit 26 and the information reception unit 28. When the main controller mode selection unit 24 is in the power saving mode or the standby mode, the job reception unit 26 is activated, and in the sleep mode, the information reception unit 28 is activated.

  The job reception unit 26 is connected to the job analysis unit 30, the transition control unit 32, and the timer circuit unit 34. When the apparatus receives a job, the job receiving unit 26 outputs an instruction signal to the job analyzing unit 30. The job analysis unit 30 executes job analysis.

  On the other hand, when receiving a job, the job receiving unit 26 outputs a transition change signal to the transition control unit 32. The job receiving unit 26 is managed by the timer circuit unit 34 and outputs a transition change signal to the transition control unit 32 when no job is received for a predetermined time (predetermined time).

  When the transition control unit 32 receives the transition change signal from the job reception unit 26, the transition control unit 32 instructs the main controller selection unit 24 to perform mode transition according to the current mode state.

  For example, in the power saving mode and when a job is received, a transition to the standby mode is instructed. On the other hand, when the current mode is the standby mode and no job is received for a predetermined time, an instruction to shift to the power saving mode is given. Further, when the current mode is the power saving mode and no job is received for a predetermined time, an instruction to shift to the sleep mode is given.

  Note that, as described above, the mode recognized by the main controller mode selection unit 24 is not necessarily reflected in each device, and a device that does not have a power saving mode transitions based on the current mode. May be different.

  As a result of the analysis by the job analysis unit 30, when a device necessary as a function for processing the job is found, the necessary device information is sent to the job execution possibility determination unit 36.

  The job execution availability determination unit 36 is connected to a mode pattern inquiry unit 38. In response to the inquiry from the job execution enable / disable unit 36, the mode pattern inquiry unit 38 inquires about the mode status of each device via the I / O 210 and returns a response to the job execution enable / disable unit 36.

  The job execution possibility determination unit 36 determines whether or not a device necessary for executing the processing function of the instructed job is in the standby mode.

  The job execution possibility determination unit 36 is connected to the mode transition instruction unit 40 and the job execution instruction unit 42.

  For this reason, if the result of determination by the job execution possibility determination unit 36 is that the required device is not in the standby mode, the mode transition instruction unit 40 is instructed to transition to the standby mode, and the required device is in the standby mode. In this case, the job execution instruction unit 42 is instructed to execute the job.

  The information receiving unit 28 receives a remote job reception signal and an operation signal of the power saving button 219 via the I / O 210. The remote job reception signal is a signal received when a print instruction or the like is received from an information processing terminal (for example, a PC or the like) via the network communication network 20 (see FIGS. 1 and 2), for example. The operation signal of the power saving button 219 is a signal received when the hardware power saving button 219 is operated separately from the UI touch panel 216 of the apparatus. Each time the power saving button 219 is operated, the power saving button shifts to and returns from power saving.

  The information receiving unit 28 is connected to the UI activation control unit 44. The UI activation control unit 44 controls the UI control circuit 214 via the I / O 210 to supply power to the UI touch panel 216 but the backlight is turned off (low power mode), or the UI touch panel is turned off. Transition to any of the states (standby mode) in which complete recovery is included.

  This selection depends on the signal received by the information receiving unit 28. That is, the backlight is turned off in the remote job reception signal, and the backlight is turned on in the operation signal of the power saving button 219.

  The operation of the present embodiment will be described below.

  FIG. 4 is a flowchart showing the flow of mode transition of the main controller 200 and each device.

In step 100, the current mode in the main controller 200 is determined.
(Standby mode)
If it is determined in step 100 that the current mode is the standby mode, the process proceeds to step 102. In step 102, it is determined whether or not a job has been received. If an affirmative determination is made, the process proceeds to step 104.

(Job execution)
In step 104, job analysis is executed, and then the process proceeds to step 106, where it is determined whether the current device mode pattern is OK as a result of job analysis. If a negative determination is made in step 106, the process proceeds to step 108 in order to change the device mode pattern, an activation instruction is output to the necessary device, and the process proceeds to step 110.

  In step 110, it is determined whether or not there is an answer to the standby mode from the device that has received the activation instruction. If an affirmative determination is made, the process proceeds to step 112.

  Further, when an affirmative determination is made at step 106, the routine proceeds to step 112.

  In step 112, a process execution instruction is output, and then the process proceeds to step 114, where the current device mode pattern is recognized based on the mode for each device, and the process returns to step 100.

  On the other hand, if a negative determination is made in step 102, it is determined whether or not a predetermined time has passed since the transition to step 116. If a negative determination is made, the process returns to step 102 and the above steps are repeated. If an affirmative determination is made in step 116, the process proceeds to step 118 to shift the main controller 200 to the “power saving mode”. Next, in step 120, the transition of the main controller 200 is notified to each device. 122.

In step 122, the current device mode pattern is recognized based on the mode for each device, and the process returns to step 100.
(Power saving mode)
Next, when it is determined in step 100 that the power saving mode is set, the process proceeds to step 124 to determine whether or not a job has been received. If the determination is affirmative, the process proceeds to step 126.

  In step 126, the main controller 200 transitions to the “standby mode”, and in the next step 128, the transition destination of this system is notified to each device, and the process proceeds to step 104. Since step 104 and subsequent (job execution) have been described above, description thereof is omitted here.

  If a negative determination is made at step 124, the routine proceeds to step 130 where it is determined whether or not a predetermined time has elapsed. If a negative determination is made in step 130, the process returns to step 124, and if a positive determination is made in step 130, the process proceeds to step 132.

In step 132, the main controller 200 is shifted to the “sleep mode”, and then in step 134, the transition destination of the main controller 200 is notified to each device, and the process proceeds to step 136. In step 136, the current device mode pattern is recognized based on the mode for each device, and the process returns to step 100.
(sleep mode)
Next, when the sleep mode is determined in step 100, the process proceeds to step 138, where it is determined whether or not the information prompting the activation is accepted, and when the determination is affirmative, the process proceeds to step 140. In step 140, it is determined whether the received information is reception of a remote job or operation of a power saving button. If it is determined in step 140 that a remote job has been received, the process proceeds to step 142, the UI touch panel 216 is transitioned to the “low power mode” (backlight off), and the process proceeds to step 126.

  In step 126, the main controller 200 transitions to the “standby mode”, and in the next step 128, the transition destination of this system is notified to each device, and the process proceeds to step 104. Since step 104 and subsequent (job execution) have been described above, description thereof is omitted here.

  If it is determined in step 140 that the power saving button has been operated, the process proceeds to step 144, the UI touch panel 216 is transitioned to “standby mode” (backlight on), and the process proceeds to step 146.

  In step 146, it is determined whether or not a function selection operation has been performed from the UI touch panel 216. If an affirmative determination is made, the process proceeds to step 126.

  In step 126, the main controller 200 transitions to the “standby mode”, and in the next step 128, the transition destination of this system is notified to each device, and the process proceeds to step 104. Since step 104 and subsequent (job execution) have been described above, description thereof is omitted here.

  On the other hand, when a negative determination is made at step 146, the routine proceeds to step 148, where it is determined whether or not a predetermined time has elapsed. If a negative determination is made in step 148, the process proceeds to step 146. If an affirmative determination is made in step 148, the UI touch panel 216 is set to the standby mode, but it is determined that there is no operation for selecting a subsequent function. ”And return to Step 100.

  FIG. 5 is a chart showing the transition state of the mode pattern. When the job is not executed and the power saving state is set, the state No. 1 or No. 2 state. This difference is whether or not the image forming unit 240 is in the power saving mode. For example, when there is an instruction to store and print by [remote user], the image forming unit 240 is an unnecessary device, and thus may transition to the sleep mode. However, in the present embodiment, the current state is No. In the case of No. 1, no. 4, the image forming unit 240 is set to the sleep mode, and the current state is No. 4. In the case of No. 2, no. 5, the image forming unit 240 maintains the power saving mode.

  When the main controller 200 enters a standby mode and executes a job, the temperature of the fixing unit can be adjusted when the image forming unit is necessary for the next job by maintaining the mode state of the image forming unit 240 that is the transition source. Convenience of job execution by starting up to a temperature that can be processed quickly, maintaining power reduction due to partial power saving, and supplying power to the minimum necessary parts such as the image forming unit 240 Sex is maintained.

  In this embodiment, control is performed so that power is supplied to the UI touch panel 216 when the mode of the main controller 200 is the power saving mode. However, power to the UI touch panel 216 is turned off in the power saving mode. Also good. In this case, in the flowchart of FIG. 4 described above, if the determination in step 130 is negative, the process proceeds to step 138, and if the negative determination in step 138 is to return to step 100, the main controller 200 sleeps in the power saving mode. The state UI touch panel 216 can be controlled.

  In the present embodiment, as shown in FIG. 2, a block diagram of a power supply control system in which a power supply destination is classified for each processing function (service) is shown, but the present invention is not limited to this. For example, power supply / shutoff is performed by directly controlling switch elements provided for each device (facsimile communication control circuit 236, image reading unit 238, image forming unit 240, and UI touch panel 216). May be performed.

  Further, in the present embodiment, the main controller 200 recognizes the three modes and issues an instruction to each device. For this reason, the image forming unit 240 maintains the power saving mode according to the mode instruction even when it is not necessary to execute the processing function. However, when the main controller 200 issues instructions only in two modes (standby and sleep), the image forming apparatus 240 that has received the sleep instructions is configured to maintain its own power supply, unlike the instructions from the main controller 200. May be.
