(Main controller 200)
FIG. 2 is a schematic configuration diagram of the 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. Further, a hard disk (HDD) 218, a power saving button 219, and a sub power switch 221 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 instructed alternately to save power and cancel power saving.

  The sub power switch 221 is called a so-called soft switch, unlike the main power switch 20 (see FIG. 3), which will be described later, and a part of the main controller 200 (for example, a boot ROM or the like) is being activated. The image processing apparatus 10 is turned on / off by the sub power switch 221. In other words, the operation of the sub power switch 221 requires a small amount of power in the main controller.

  The main controller 200 according to the present embodiment instructs the image processing device to enter a standby mode and a sleep mode. The standby mode is a power supply state, and the sleep mode is a power cutoff state. In the present embodiment, the main controller 200 itself may be in a power cut-off state (sleep 0 state).

  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.

  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 image processing device (facsimile communication control circuit 236, image reading unit 238, image forming unit 240) are supplied with power from the power switching controller 12 (see FIG. 3).

(Power supply system)
FIG. 3 shows a system diagram for supplying power to the main controller 200 and each image processing device as shown in the present embodiment. In FIG. 3, when there is no intervening power supply line, it is indicated by a thick solid line, and when a physical inclusion is present in the middle of the power supply line, it is indicated by two thin solid lines (real wiring).

  The image processing apparatus 10 is supplied with electric power by inserting an outlet 18 into a wiring plate 16 of a commercial power source 14 wired to a wall surface W as shown in FIG.

  As shown in FIG. 3, the outlet 18 is connected to one end of the main power switch 20. The other end of the main power switch 20 is connected to the power switching controller 12 via the triac 22.

  A first low voltage supply unit 26 (hereinafter sometimes referred to as “LVPS1”) is connected to the downstream side of the triac 22. Although illustration of wiring is omitted, on the downstream side of the triac 22, in addition to the LVPS 1, a second low voltage supply unit 28 (hereinafter sometimes referred to as “LVPS2”) and a fixing unit voltage supply unit 24 are provided. It is connected.

  The LVPS 1 is mainly applied as a power source for the main controller 200.

  The LVPS 2 is mainly applied to the operation system of the image forming unit 240, the image reading unit 238, and the facsimile (FAX) communication control circuit 236.

  The fixing unit voltage supply unit 28 is mainly applied to heating a heater (such as a halogen lamp or an IH heater) applied to the fixing unit of the image forming unit 240.

  A power storage device 30 is connected to the power switching controller 12. That is, in this embodiment, a first mode for supplying commercial power to the main controller 200 and a second mode for supplying power from the power storage device 30 are set.

  The power storage device 30 is configured to store a predetermined amount of power, and as its power source, in addition to the power generated by the solar panel 33, power from regenerative energy (not shown) is charged. There is. The commercial power supply 14 may be charged by being supplied with power. Further, as the power storage device 30, a dry battery or the like is applicable regardless of whether or not charging is possible.

  As an example, the power storage device 30 is set so that 70% of the power is charged with power from the commercial power supply 14 and the remaining 30% is charged with power from the solar panel 33 or the like. This setting is merely an example, and all the settings may be performed by charging with the solar panel 33 or the like.

  In the main controller 200, when the reception of processing (hereinafter may be referred to as “job”) is not continued for a predetermined time or when the power saving button 219 is operated, the image processing device (image forming unit 240). Then, control is performed to cut off the power supply to the image reading unit 238 and the facsimile (FAX) communication control circuit 236).

  At this time, the power switching controller 12 also cuts off the supply of power from the commercial power supply 14 to the main controller 200 when the power amount of the power storage device 30 is equal to or greater than a predetermined power amount. This power interruption is realized by cutting off the power supply to the triac 22 from the main controller 200 via the power switching controller 12. For this reason, the main controller 200 loses most of its functions.

  However, in a part of the main controller 200, it is necessary to supply power only to an IC chip (for example, boot ROM) that returns a function in response to an activation signal such as operation of the sub power switch 221 or remote job reception. The electric power stored in the electric storage device 30 is supplied. The power consumption of the main controller 200 at this time is, for example, about 0.5 W to 1.5 W.

  Since the image processing apparatus 10 in this state does not receive any power from the commercial power supply 14, the power consumption is 0 (“sleep 0” state).

  In this state, for example, when an operation of the sub power switch 221 or a remote job is accepted (that is, when a print instruction or the like is accepted from the network communication line), the main controller 200 is activated by the activation program. This activation is realized when the power switching controller 12 energizes the triac 22.

  At this time, in the present embodiment, it is assumed that the startup processing (triac 22 is turned on) is performed using the power from the power storage device 30, but for example, the sub power switch 221 is operated. When the power is turned off and the main power switch 20 is turned off, it is not in the “sleep 0” state but in a completely off state. For example, when the image processing apparatus 10 is moved, naturally, the power switch 20 is turned off or the outlet 18 is disconnected.

  In such a case, it is not necessary to maintain the “sleep 0” state of quickly starting up when receiving a remote job. In other words, there is no power in the power storage device 30 and no power is supplied to the main controller 200 or the like.

  Therefore, in this embodiment, at the time of return from the complete power cut-off state or the sleep mode (“sleep 0” state), at least the return by the operation of the sub power switch 221 is a commercial power supply power return circuit triggered by a manual operation. 31 (see FIG. 3) was formed.

  As shown in FIG. 3, the commercial power supply power recovery circuit 31 is branched from the downstream side of the main power switch 20 and the upstream side of the triac 22, and an auxiliary switch element 32 that is manually turned on is interposed. A start-up wiring circuit 34 wired directly from the main power switch 20 (commercial power supply 14) to the LVPS 1 is provided.

  The auxiliary switch element 32 has a partial relay switch function. That is, the switch portion 32A that can manually connect the wiring of the start-up wiring circuit 34 to a connected state (ON state), and the connection state (ON state) of the switch portion 32A by a magnetic force is opened (OFF). A coil portion 32B is provided. One end of the coil portion 32B is connected to the wiring 36 output from the power switching controller 12, and the wiring 38 connected to the other end of the coil portion 32B is grounded. The wirings 36 and 38 and the coil portion 32B function as the excitation circuit 40.

  Further, between the main controller 200, the power switching controller 12, and the LVPS 1, power is distributed to the main controller 200 and the power switching controller 12 from the LVPS 1 that is supplied with power from the commercial power supply 14 through the startup wiring circuit 34. Special wirings 42 and 44 are formed.

  A conventional power supply line 46 including the power storage device 30 is provided between the main controller 200, the power switching controller 12, and the LVPS 1 (shown by a bold solid line in FIG. 3). It is preferable to provide wirings 42 and 44 separately from the existing power supply line 46.

  The power recovery (first normal mode transition control) using the commercial power supply power recovery circuit 31 (and the startup wiring circuit 34, the auxiliary switch element 32, and the excitation circuit 40) is a power recovery using the power of the power storage device 30 (first normal mode transition control). The commercial power supply return is realized without using the second normal mode transition control).

  For example, when the main power switch 20 is in the off state, the main power switch 20 is turned on and the sub power switch 221 is turned on, and then the switch portion 32A of the auxiliary switch element 32 is manually turned on. Operation starts.

  The start-up wiring circuit 34 supplies the power of the commercial power supply 14 to the LVPS 1 by the auxiliary switch element 32.

  With the supply of power from the commercial power supply 14, the LVPS 1 supplies power to the main controller 200 and the power switching controller 12 to start up.

  When the power switching controller 12 is activated, the TRIAC 22 is controlled to restore the power supply line from the commercial power supply 14 of the steady route.

  Note that after the power supply line is restored from the commercial power supply 14 of the steady route, the power switching controller 12 energizes the excitation circuit 40 to excite the coil portion 32B of the auxiliary switch element 32, thereby switching the switch. The part 32A is turned off.

In the present embodiment, the application of the commercial power supply power recovery circuit 31 is not limited. For example, the following forms can be considered.
(Application 1) Used in combination with power recovery by the power storage device 30 (triac 22 on operation), the power of the power storage device 30 is used in the sleep mode, and the power is cut off by the main power switch 20 or the sub power switch 221 being turned off. In some cases, the commercial power supply power recovery circuit 31 is used.
(Use 2) The commercial power supply power recovery circuit 31 is used as emergency means when the power of the electricity storage device 30 is equal to or lower than a predetermined threshold.
(Usage 3) Separately, the on / off state of the main power switch 20 is monitored, and at the time of recovery, the commercial power supply power recovery circuit 31 is used only when the operation starts from the main power switch ON.

  Hereinafter, the operation of the present embodiment will be described.

  4 and 5 are flowcharts showing the flow of power supply control mainly including the realization of “sleep 0” using the power storage device 30 and the power recovery operation of the commercial power supply 14 using the power storage device 30.

  FIG. 4 shows power supply control in the main controller 200. In step 100, it is determined whether or not a job has been accepted. If an affirmative determination is made, the process proceeds to step 102 to perform job execution processing. Ends.

  Further, if a negative determination is made in step 100, it is determined whether or not a predetermined time has passed after moving to step 104. If a negative determination is made in step 104, the process proceeds to step 106 to determine whether or not the power saving button 219 has been operated. If a negative determination is made in step 106, the process proceeds to step 108, where it is determined whether or not an off instruction has been given by operating the sub power switch 221. If an affirmative determination is made in step 108, the process proceeds to step 109, the complete power cut-off process of the image processing apparatus 10 is executed, and this routine ends. If the determination at step 108 is negative, this routine ends. The complete power cut-off process refers to shutting off the power to various devices and the like while leaving only the operating power of the start program that is started based on the ON operation by the sub power switch 221 instead of the sleep state. After this, the main power switch 20 may be turned off.

  If an affirmative determination is made in step 104, the process proceeds to step 110, the image processing device is shifted to the sleep mode, then the process proceeds to step 112, the electric energy of the power storage device 30 is read, and the process proceeds to step 114. In step 114, it is determined whether or not a sufficient amount of electric power has been accumulated even if the commercial power source 14 is shut off (whether the commercial power source is OK). Transition to mode. The second mode is a mode in which power is supplied from the power storage device 30.

  In the next step 118, the control subject is transferred to the power switching controller 12, and this routine ends. Further, if the determination in step 114 is negative, that is, it is determined that the commercial power supply 14 cannot be shut off (determined that the power consumption of the storage device 30 is insufficient), the main controller 200 is supplied with power from the commercial power supply 14. This routine ends. Although not described in this flowchart, for example, when charging from the commercial power supply 14 or the solar panel 33 proceeds and the power storage device 30 has a sufficient amount of power, the mode may be changed to the second mode. Good.

  If an affirmative determination is made in step 106, that is, if the power saving button 219 is operated, the control is the same as the affirmative determination (when a predetermined time has elapsed) in step 104. Execute.

  Next, FIG. 5 shows power supply control in the power switching controller 200. In step 152, it is determined whether or not the power saving button 219 has been operated. It is determined whether there is job reception information from the controller 200. If a negative determination is made in step 154, the process returns to step 152 and is repeated until an affirmative determination is made in any of steps 152 and 154.

  If an affirmative determination is made in step 152 or step 154, the process proceeds to step 156, and a transition is made to the first mode. The first mode is a mode in which electric power is supplied from the commercial power source 14, and specifically, an operation for turning on the triac 22.

  In the next step 158, it is determined whether or not the main controller 200 has risen to a controllable state. This “rising up to a controllable state” determines whether or not the power of the commercial power supply 14 is supplied to the primary side of the LVPS1 and LVPS2 and a normal voltage (for example, 5V) is output from the secondary side. If an affirmative determination is made in step 158, the process proceeds to step 166, the control subject is transferred to the main controller 200, and the power supply control in the power switching controller 12 is terminated.

  Here, when the operation of the sub power switch 221 is instructed to be turned off in Step 108 of FIG. 4 and the main power switch 20 is also turned off, it is unclear how long the period is, A state in which the amount of power of the power storage device 30 does not remain (or there is no power to turn on the triac 22) is also conceivable.

  Therefore, in the present embodiment, a commercial power supply power recovery circuit 31 (see FIG. 3) is provided for recovering the power supply of the commercial power supply 14 that is activated when the main power switch 20 is turned on.

  FIG. 6 is a flowchart showing an operation flow of the commercial power supply power recovery circuit 31, and FIG. 7 is a timing chart thereof. In addition, in FIG. 6, although the flow of operation | movement of the commercial power supply electric power return circuit 31 is shown by the flowchart (startup routine at the time of main power switch ON), a part shall include operation | movement by an electric circuit.

  In step 170, it is determined whether or not the sub power switch 221 is turned on. If an affirmative determination is made, the process proceeds to step 172 to determine whether or not the commercial power can be maintained on the normal route. For example, when the power is cut off by the sub power switch 221 during the normal mode, the determination is affirmative. Note that a positive determination may also be made when the power of the electricity storage device 30 is sufficient and the operation of the triac 22 is surely possible.

  When an affirmative determination is made at step 172, the routine proceeds to step 174, where normal return processing is executed, and this routine ends. The normal recovery process includes starting up each device by turning on the LVPS 2 and the fixing unit voltage supply unit 24.

  If a negative determination is made in step 172, the process proceeds to step 176, and it is determined whether or not the switch part 32A of the auxiliary switch element 32 is turned on. If an affirmative determination is made in step 176, it means that the power of the commercial power supply 14 has been supplied to the LVPS 1, and the process proceeds to step 178 to supply power to the main controller 200 and the power switching controller 12.

  In the next step 180, the power switching controller 12 that has received power from the LVPS 1 controls the triac 22 to turn it on. As a result, the power supply line from the commercial power supply 14 of the steady route is restored, and the process proceeds to step 182.

  In step 182, the recovery of the power supply line from the commercial power supply 14 of this steady route is confirmed. If an affirmative determination is made, the process proceeds to step 184 to energize the excitation circuit 40 and excite the coil section 32B. With the excitation of the coil portion 32B, the switch portion 32A that is manually turned on is turned off, and the process proceeds to step 174. Note that this routine is partly a software control of the power switching controller 12, but for example, whether or not the switch unit 32A of the auxiliary switch element 32 is turned on (step 176), the main controller 200, the power switching controller. 12 until the power supply to 12 (step 178) or the energization of the excitation circuit 40 (step 182) to the switch element 32A being turned off by excitation of the coil part 32B (step 184) is an operation by an electric circuit. Therefore, the period of the alternate long and short dash line in the timing chart of FIG. 7 is executed almost instantaneously although a time width indicated by the alternate long and short dash line is provided for explaining the operation.

  In the present embodiment, the power supply recovery of the commercial power supply 14 by the commercial power supply power recovery circuit 31 and the power supply recovery of the commercial power supply 14 using the power of the power storage device 30 are used in combination. The power supply recovery of the commercial power supply 14 by the commercial power supply power recovery circuit 31 may be performed.

  Further, as an emergency measure when the power of the power storage device 30 is insufficient, the power supply recovery of the commercial power supply 14 by the commercial power supply power recovery circuit 31 may be applied (emergency countermeasure).

(Realization of sleep 0)
When switching from the normal mode to the sleep mode, the power saving button 219 may be operated. At this time, the main controller 200 instructs the power switching controller 12 to turn off the triac 22. As a result, the triac 22 is turned off. At the same time, the power supply from the LVPS 1 is cut off by outputting a sleep signal from the main controller 200 to the LVPS 1. Thereby, the power supply from the commercial power source 14 becomes “0” W, and the main controller 200 and the power switching controller 12 realize a so-called “sleep 0” state in which power is supplied from the power storage device 30.

(Modification)
As shown in FIG. 8, among the existing power supply lines 46 (thick solid lines) shown in the present embodiment, the main power switch 20 is in the middle of wiring from the power storage device 30 to the main controller 200 and the power switching controller 12. By interposing the switch element 20 </ b> A that is linked to on / off of the power storage device 30, power consumption of the power storage device 30 when the main power switch 20 is off is eliminated. In other words, the main controller 200 and the power switching controller 12 are in a complete power cutoff state.

  For this reason, in the modified example, the power of the power storage device 30 is not inadvertently consumed. Therefore, the main power switch 20 is turned on after the main power switch 20 is turned on, and then the commercial power supply 14 is turned on after the sub power switch 221 is turned on. The probability of being able to do with the electric power of the electricity storage device 30 is increased. On the contrary, by adopting such a configuration, the commercial power supply power recovery circuit 31 can be used in an emergency.
