When all the processing units are saved, the monitoring control unit 24 (described later) receives the minimum necessary power and supplies power to other control devices. (There is sometimes referred to as “power saving mode” or “sleep mode”).

[Main controller 200]
As shown in FIG. 4, 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.

  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 dotted line in FIG. 4). In FIG. 4, the power supply line is shown by one line (dotted line), but in reality it is two to three wires.

[Power supply device 202]
As shown in FIG. 4, 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 second power supply unit 250 via the first power supply unit 248 and the first sub power supply switch 256.

  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 for conducting / non-conducting the power supply line to 240).

  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. That is, when the SW-1 is off, the second power supply unit 250 does not function (the power consumption is in the zero state on the downstream side of “SW-1”).

  The second power supply unit 250 includes a 24V power supply unit 250H (LVPS2) and a 5V power supply unit 250L (LVPS1). The 24V power supply unit 250H (LVPS2) is a power supply mainly used for a motor or the like.

  The 24V power supply unit 250H (LVPS2) and the 5V power supply unit 250L (LVPS1) of the second power supply unit 250 selectively supply an image reading unit power supply unit 258, an image forming unit power supply unit 260, and a facsimile communication control circuit power supply. 264 and the UI touch panel power supply unit 266.

  The image reading unit power supply unit 258 uses the 24V power supply unit 250H (LVPS2) as an input source, and the image reading unit 238 via a second sub power switch 268 (hereinafter also referred to as “SW-2”). It is connected to the.

  The image forming unit power supply unit 260 uses a 24V power supply unit 250H (LVPS2) and a 5V power supply unit 250L (LVPS1) as input sources, and a third sub power switch 270 (hereinafter sometimes referred to as “SW-3”). And connected to the image forming unit 240.

  The facsimile communication control circuit power supply unit 264 may be referred to as a fourth sub power switch 274 (hereinafter “SW-4”) with the 24V power supply unit 250H (LVPS2) and the 5V power supply unit 250L (LVPS1) as input sources. ) To the facsimile communication control circuit 236 and the image forming unit 240.

  The UI touch panel power supply unit 266 uses a 5V power supply unit 250L (LVPS1) and a 24V power supply unit 250H (LVPS2) as input sources and a fifth sub power switch 276 (hereinafter may be referred to as “SW-5”). Via the UI touch panel 216 (including the backlight unit 216BL).

  Similarly to the first sub power switch 256, the second sub power switch 268, the third sub power switch 270, the fourth sub power switch 274, and the fifth sub power switch 276 are the main controller 200. On / off control is performed on the basis of a power supply selection signal from the power supply control circuit 252. Although not shown, the switches and wirings to which the 24V power supply unit 250H and the 5V power supply unit 250L are supplied are composed of two systems. Further, the power switches 268 to 276 may be arranged in each device that is the power supply destination instead of the power supply device 202. Further, the fixing unit (corresponding to “Fuser” shown in FIG. 3) of the image forming unit (not shown) is connected to the commercial power source 242 (for example, 100 V) by the first sub power switch 256 (“SW-1”). Directly supplied from the downstream side and energized only when necessary in the image forming unit 240.

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

(Supervisory control for state transition of image processing device)
Here, the main controller 200 of the present embodiment may partially stop its function (partial power saving) so that the necessary minimum power consumption is achieved. Alternatively, the power supply may be stopped including the majority of the main controller 200 (“sleep mode (power saving mode)).

  The sleep mode can be shifted, for example, by starting a system timer when image processing is completed. That is, the power supply is stopped when a certain time has elapsed since the system timer was started. If there is any operation (hard key operation, etc.) before the predetermined time elapses, the timer count to the sleep mode is naturally canceled and the system timer is started from the end of the next image processing. Note that the shorter the fixed time measured by the system timer is, the better the energy saving performance, but the convenience is impaired. In addition, the longer the fixed time counted by the system timer, the better the convenience, but the energy saving performance is impaired.

  On the other hand, during the sleep mode, a power-saving monitoring control unit 24 (see FIG. 4) is connected to the I / O 210 as an element that is constantly supplied with power. The power-saving monitoring control unit 24 may include, for example, an IC chip called an ASIC, which stores an operation program by itself and is processed by the operation program, including a CPU, RAM, ROM, and the like. Good.

  In the power saving monitoring control unit 24, for example, when a print request is received from the communication line detection unit or a FAX reception request is received from the FAX line detection unit in the monitoring during power saving, the power saving monitoring control unit 24 Through the power supply control circuit 252, the first sub power switch 256, the second sub power switch 268, the third sub power switch 270, the fourth sub power switch 274, and the fifth sub power switch 276 are provided. By controlling, power is supplied.

(Main controller power supply / cut-off control)
Further, as shown in FIG. 4, a power saving control button 26 (sometimes simply referred to as “power saving button 26”) is connected to the I / O 210 of the main controller 200. The sleep mode can be canceled by operating the power saving control button 26. The power saving control button 26 also has a function of being operated when power is supplied to the processing unit, thereby forcibly cutting off the power supply of the processing unit and setting the power saving state. An IC card reader 217 is connected to the I / O 210 of the main controller 200.

  Here, in order to monitor in the sleep mode, it is preferable to supply the minimum necessary power to the power saving control button 26 and a predetermined detection unit in addition to the power saving monitoring control unit 24. That is, even in the sleep mode in which the power is not supplied, there is a case where the power is not more than a predetermined power (for example, 0.5 W or less) and is supplied with the power necessary for determining whether to supply power. is there.

  As a specific period of the sleep mode, a period for supplying the minimum necessary power supply mainly including an input system such as the main controller 200, the UI touch panel 216, and the IC card reader 217 may be provided. This is in consideration of convenience for the user. Also, it is not particularly important whether the specific period of the sleep mode is still defined as the sleep mode or as another mode. For example, if the definition of the sleep mode is “less than power consumption such as a predetermined energy saving level”, whether or not the power consumption in a specific period of the sleep mode is maintained below the predetermined energy saving level. Judge by.

  For example, when the user operates the power saving control button 26 during the sleep mode to copy as a processing function, as a specific period, first, the main controller 200 is started up, the UI touch panel 216 is operated, After making the card authentication by the IC card reader 217 possible, it is possible to achieve both convenience and energy saving by selecting a device and supplying power in accordance with the operation status of the user. This specific period may be during human detection by a human sensor described later.

(Function of human sensor)
By the way, when the user stands in front of the image processing apparatus 10 in the sleep mode and then operates the power saving control button 26 to restart the power supply, it may take time until the image processing apparatus 10 starts up. .

  Therefore, as the “automatic return mode”, human sensors (in the present embodiment, the first human sensor 28 and the second human sensor 30) are installed in the power saving monitoring control unit 24, and the sleep mode is set to sleep. In the mode, the user detected it with a human sensor before pressing the power saving release button and restarted the power supply at an early stage so that the user can use it quickly.

  As shown in FIG. 4, the first human sensor 28 and the second human sensor 30 include detection units 28A and 30A and circuit board units 28B and 30B, and the circuit board units 28B and 30B The sensitivity of the signals detected by the detection units 28A and 30A is adjusted and an output signal is generated.

  The first human sensor 28 and the second human sensor 30 are “human feeling”, but this is a proper noun according to the present embodiment, and at least if a person can sense (detect) it. In other words, it also includes sensing (detection) of moving objects other than humans. Therefore, in the following, the detection target of the human sensor may be referred to as “person”, but in the future, a robot or the like that executes on behalf of a person is also within the detection target range. On the other hand, when there is a special sensor that can be identified and identified as a person, the special sensor can be applied. Hereinafter, a moving body, a person, a user, and the like are treated as synonymous as objects to be detected by the first human sensor 28 and the second human sensor 30, and are distinguished as necessary.

"First human sensor 28"
The specification of the first human sensor 28 according to the present embodiment is to detect the movement of the moving body around the image processing apparatus 10 (for example, in a range of 1 m to 5 m). In this case, an infrared sensor using the pyroelectric effect of the pyroelectric element is representative (pyroelectric sensor). In the present embodiment, a pyroelectric sensor is applied as the first human sensor 28.

  The greatest feature of the sensor using the pyroelectric effect of the pyroelectric element applied to the first human sensor 28 is that the detection area (including the diffusion width and the detection distance) is wide. Further, since the movement of the moving body is sensed by a temperature change, the presence of the person is not detected if the person is stationary within the detection region. For example, when a high-level signal is output when a person moves, the signal becomes a low-level signal when a person within the detection range stops.

  Note that “still” in the present embodiment naturally includes complete stillness such as a still image taken with a still camera or the like. For example, a person stops before the image processing apparatus 10 for the purpose of operation. Shall be included. Accordingly, a case where a predetermined range of fine movement (such as movement accompanying breathing) or movement of a limb, neck, or the like is set as a stationary category.

  However, if a person performs a stretching exercise or the like in front of the image processing apparatus 10 while waiting for processing such as image formation or image reading, the human sensor 28 may detect the presence of the person. .

  Therefore, instead of defining the “still” and setting a threshold value for motion detection by the first human sensor 28, the threshold value is set relatively roughly and standardly, and the environment ( You may make it depend on the detection state of the said 1st human sensitive sensor 28 based on temperature, humidity, etc.). That is, a person is moving when the first human sensor 28 outputs one of the binary signals (for example, a high level signal) experimentally or statistically at the device installation location. When a person is present in the detection area of the second first human sensor 28 and another one of the binary signals (for example, a low level signal) is output, What is necessary is just to set the threshold value which carries out.

  The specification of the first human sensor 28 according to the present embodiment is to detect the movement of the moving body around the image processing apparatus 10 (for example, in the range of 0 m to 5 m).

"Second human sensor 30"
On the other hand, the specification of the second human sensor 30 according to the present embodiment is applied to detect the presence / absence (presence / absence) of a moving body. The sensor applied to the second human sensor 30 is typically a reflective sensor having a light projecting part and a light receiving part (reflective sensor). Note that the light projecting unit and the light receiving unit may be separated.

  The greatest feature of the reflective sensor or the like applied to the second human sensor 30 is to reliably detect the presence or absence of a moving body by blocking / not blocking light entering the light receiving unit. In addition, since the amount of light incident on the light receiving unit is limited by the amount of light projected from the light projecting unit, a relatively short distance is the detection region.

  If the first human sensor 28 and the second human sensor 30 can achieve the following functions, the first human sensor 28 may be a pyroelectric sensor or a second human sensor. The human sensor 30 is not limited to a reflective sensor.

  Here, in the present embodiment, the maximum detection range (for example, the first region F and the second region N in FIGS. 6 and 7) by the first human sensor 28 and the second human sensor 30. It was set.

  The first region F in FIG. 6 which is a relatively distant detection region (sometimes simply referred to as “region F”) is a detection region by the first human sensor 28 and is a relatively remote mobile object. It has a function as a detection means. Further, the second region N in FIG. 6 (which may be simply referred to as “region N”), which is a relatively close detection region, is a detection region by the second human sensor 30 and is relatively close. It has a function as a moving body detection means.

  The detection area of the first human sensor 28 (see the first area F in FIG. 6) has a critical point (the farthest position) as a guide, although it depends on the environment where the image processing apparatus 10 is installed. About 0.8 to 3 m is preferable. On the other hand, the detection area of the second human sensor 30 (see the second area N in FIG. 6) is a range in which the UI touch panel 216 and hard keys of the image processing apparatus 10 can be operated. (The farthest position) is preferably about 0.2 to 1.0 m. Of course, after setting both, the critical point of the first human sensor 28 becomes farther than the critical point of the second human sensor 30.

(Configuration of the first human sensor 28, the second human sensor 30 and the surroundings)
As shown in FIG. 7, the image processing apparatus 10 includes an image reading device 238, an image forming device 240, and the like that are covered with a housing 300, and the first human sensor 28 (the second human sensor 30 is replaced by the first human sensor 28. Are attached to a vertically long rectangular pillar 302 in the housing 300. The pillar portion 302 is a portion that connects the upper housing 300A that covers the image reading device 238 and the lower housing 300B that covers the image forming device 240, and a recording paper conveyance system or the like is assembled therein.

  A vertically long rectangular cover member 304 that covers the pillar portion 302 with a design element is attached to the front surface of the pillar portion 302.

  A gap (not shown) is provided between the lower surface of the cover member 304 and the upper surface of the lower housing 300B. Further, as shown in FIG. 8, the lower end portion of the cover member 304 has a so-called chamfering (chamfered portion 304A) shape, and the opening of the gap portion between the lower surface of the cover member 304 and the upper surface of the lower housing 300B described above. The area is larger than the gap size on the back side.

  The chamfered portion 304A is provided with a rectangular through-hole 304B, and the first human sensor 28 is attached thereto. For this reason, the through hole 304 </ b> B serves as a monitoring window for detecting the moving body by the first human sensor 28. Hereinafter, the through hole 304B may be referred to as a monitoring window 304B.

  Here, since the monitoring window 304B is formed in the chamfered portion 304A, the monitoring window 304B is less visible from the front of the apparatus than that formed on the front surface, and does not impair the design elements of the cover member 304. .

  Further, as shown in FIG. 8, a vertically long slit hole 310 is provided at the upper end portion of the cover member 304 in FIG. 8, and the second human sensor 30 is provided on the back side of the slit hole 310. Has been placed. The second human sensor 30 includes a light receiving unit 30IN and a light projecting unit 30OUT as the detection unit 30A, and the detection unit 30A is attached to the circuit board unit 30B. The circuit board portion 30B is attached to the base member 306.

(Sensor power supply control)
In the present embodiment, the second human sensor 30 is not always supplied with power. The second human sensor 30 starts operating when power is supplied when the moving body (user) enters the first region F of FIG. 6 managed by the first human sensor 28. When the moving body (user) enters the second area N of FIG. 6 under the jurisdiction of the second human sensor 30, the start-up from the sleep mode to the standby mode is instructed.

  That is, two human sensors (the first human sensor 28 and the second human sensor 30) having different detection areas cooperate with each other to receive the minimum necessary power supply.

  On the other hand, in the “automatic return mode”, regarding the interruption of the power supply of the second human sensor 30, in addition to the moving body detection status of the first human sensor 28, the power saving monitoring control unit 24 is provided. The timer function is used together. This timer function is sometimes referred to as a “sensor timer” in order to distinguish it from the system timer described above.

  The sensor timer is one of the functions of the power saving monitoring control unit 24. That is, the control system is naturally provided with an operation clock, and a timer may be generated from this clock signal, or a counter program may be generated that counts every processing every predetermined time.

  As shown in FIG. 6, the relationship between the moving object (user) and the image processing apparatus 10 is roughly divided into three forms. In the first form, a person operates the image processing apparatus 10 for the purpose of use. The form approaching to the possible position (see the trend of arrow A in FIG. 6 (A pattern)), the second form is a form in which the person approaches the operable position, although the processing device is not intended for use ( In the third form, the person does not approach the operable position of the processing apparatus, but the third form is likely to shift to the first form or the second form. It is the form (refer the trend (C pattern) of the C line arrow of FIG. 6) which is made to a certain distance.

In the present embodiment, based on the detection information by the first human sensor 28, the detection information by the first human sensor 28, and the time information of the sensor timer, the trends (the A pattern to the C pattern shown in FIG. 6). The power supply timing and the power supply cutoff timing of the second human sensor 30 are controlled in accordance with the person's movement mode based on the above.
(Enable / disable automatic return mode)
As described above, using the first human sensor 28 and the second human sensor 30 to monitor the approach of the moving body and control the power supply is defined as the “automatic return mode”. In the present embodiment, enable / disable of the “automatic return mode” can be selected.

  In the case where the “automatic return mode” is valid, when the user who gives an operation instruction or the like to the image processing apparatus 10 leaves, that is, a detection region (region N in FIG. 6) by the second human sensor 30. ), The image processing apparatus 10 is set in a power saving state (power supply cut-off to each device) after a predetermined time has elapsed based on the time measurement information of the sensor timer.

  On the other hand, when the automatic return mode is invalid (hereinafter referred to as “automatic return release mode”), the moving of the moving body by the first human sensor 28 and the second human sensor 30 is performed during the power saving mode. Avoid monitoring. For this reason, the trigger for returning from the power saving mode (power supply) is left to the operation of the power saving control button 26 by the user.

  Even in the “automatic return cancellation mode”, monitoring in the first human sensor 28 and the second human sensor 30 is applied to control when the power supply state is changed to the power supply cancellation state (sleep mode). To do.

  For this reason, at least after returning from the sleep mode (power supply), it is necessary to supply power to the first human sensor 28 and the second human sensor 30.

  In this case, as in the “automatic return mode”, electric power is always supplied to the first human sensor 28, and the second human sensor 30 detects a moving body with the first human sensor 28. Electric power may be supplied, or electric power may be supplied to the first human sensor 28 and the second human sensor 30 when the power saving control button 26 is operated.

  Incidentally, in the “automatic return mode”, the transition to the sleep mode occurs after a certain time has elapsed since the second human sensor 30 no longer detects the user (from no detection).

  When the “automatic return cancellation mode” is selected, when power is unnecessarily consumed when the system timer or the power saving control button 26 is operated as a trigger for transition to the sleep mode, energy saving is reduced. There is.

  Therefore, in the present embodiment, when the power is supplied to the image processing apparatus 10, the first human sensor is used in any of the “automatic return mode” and the “automatic return release mode” when transiting to the sleep mode. The functions of 28 and the second human sensor 30 are utilized to make a transition to the sleep mode.

  In other words, in the “automatic return mode”, the functions of the first human sensor 28 and the second human sensor 30 are used for both the return from the power saving mode and the transition to the power saving mode. In the “release mode”, the functions of the first human sensor 28 and the second human sensor 30 are used for transition to the power saving mode.

  More specifically, in the “automatic return mode”, as shown in FIG. 9A, when the second human sensor 30 no longer detects a moving body (see symbol A4 in FIG. 9A). ) When the sensor timer is started and a predetermined time (see time width t1 in FIG. 9A) has elapsed, the power supply to the second human sensor 30 and each device is cut off, and the power saving mode (See reference A5 in FIG. 9A).

  On the other hand, in the automatic return release mode, as shown in FIG. 9B, when the second human sensor 30 no longer detects the moving body (see reference B5 in FIG. 9B), each device directly When the first human sensor 28 no longer detects a moving body (see reference numeral B6 in FIG. 9B), the electric power is supplied to the second human sensor 30. Is turned off to enter power saving mode.

  The difference in function between the automatic return mode and the automatic return release mode is shown in Table 1 below.

In the present embodiment, the selection of whether the “automatic return mode” is valid or invalid is set, for example, in a selection item of the UI touch panel 216 and can be set as appropriate by the user. Alternatively, the “automatic return mode” valid / invalid selection function may be set in a function key (so-called hard key) provided along with the power saving control button 26 and the numeric keypad. Further, the validity / invalidity of the “automatic return mode” is set by selection at the time of shipment, and the setting change may be left to a service person.

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

(Mode transition of power supply control of image processing apparatus 10 (device))
First, based on FIG. 5, a timing chart showing each mode state and an event that triggers the transition of the mode state in the image processing apparatus 10 is shown.

  If the image processing apparatus 10 is not processed, the operation state is the sleep mode, and in this embodiment, power is supplied only to the power-saving monitoring control unit 24.

  Here, when there is a start opportunity (detection of a start trigger such as user detection by the second human sensor 30 or operation of the power saving control button 26, etc.), the operation state transitions to the warm-up mode.

  Note that after the trigger for the start-up, the sleep mode may still be defined, but the power supply amount is increased by the activation of the main controller 200 and the UI touch panel 216 as compared with the power supply of the power-saving monitoring control unit 24 alone. . Further, for example, when returning by the operation of the power saving control button 26, the mode returns to the mode for selecting a job, which device is activated depending on the selected job, and when the image forming unit 240 is not activated, it is not warmed up There is also.

  The start-up trigger includes, for example, a human detection by the cooperation of the first human sensor 28 and the second human sensor 30, a power saving canceling operation by the user's operation of the power saving control button 26, for example, human feeling It may be a signal based on a detection result by a sensor or an operation authentication of the IC card reader 217.

  In the warm-up mode, the image processing apparatus 10 (mainly, the temperature of the fixing unit of the image forming unit 240) is brought into a processable state, so that the power consumption is the maximum in each mode. By using an IH heater as the heater, the warm-up mode time is relatively shorter than that of a heater using a halogen lamp. An IH heater and a halogen lamp can be used in combination.

  When the warm-up operation in the warm-up mode is completed, the image processing apparatus 10 transitions to the standby mode. The warm-up operation is a mode that consumes the most power (for example, 1200 W).

  The standby mode is literally a “preparation is complete in preparation” mode, and the image processing apparatus 10 is ready to execute an image processing operation.

  For this reason, when there is a job execution operation as a key input, the operation state of the image processing apparatus 10 transitions to the running mode, and image processing based on the instructed job is executed.

  When the image processing is completed (when a plurality of continuous jobs are waiting, when all the continuous jobs are completed), the operation state of the image processing apparatus 10 is changed to the standby mode by the standby trigger. Note that, after image processing, timing by a system timer may be started, and after a predetermined time has elapsed, a standby trigger may be output to transition to the standby mode.

  If there is a job execution instruction during the standby mode, the mode transitions to the running mode again, and transitions to the sleep mode when a predetermined time based on the timing of the sensor timer after the detection of the falling trigger is detected or after the detection of the falling trigger. It is supposed to be. In the present embodiment, the trigger for falling is non-detection of the moving body by the second human sensor 30.

  Further, the mode state transitions in the actual operation of the image processing apparatus 10 do not all proceed in time series as shown in this timing chart. For example, the process may be stopped in the standby mode after the warm-up mode and the mode may be shifted to the sleep mode.

  As described above, the image processing apparatus 10 according to the present embodiment transits between the modes, and the power consumed for each mode is different.

  In the present embodiment, power supply control is performed for each device. For example, when an image reading process is instructed from the sleep mode, the image reading unit is not started without starting the image forming unit 240. So-called partial power saving, such as energizing 238, is possible.

(Monitoring by the first human sensor 28 and the second human sensor 30 during the sleep mode)
Here, in the present embodiment, it is possible to select to enable or disable the “automatic return mode”. When the “automatic return mode” is valid, the return is executed from the sleep mode depending on the first human sensor 28 and the second human sensor 30. Hereinafter, a detailed flow of returning from the sleep mode will be described.

  During the sleep mode, basically, only the first human sensor 28 is supplied with power and monitors the approaching state of the moving body. This monitoring region (detection region) corresponds to the region F in FIG. 6, and the analysis (change amount) of the electric signal based on the infrared rays input to the detection unit 28 </ b> A of the first human sensor 28 is performed. The presence or absence is detected.

  When a moving body is detected by the first human sensor 28 (moving body detection in the region F in FIG. 6), power supply to the second human sensor 30 is started.

  The second human sensor 30 is closer to the image processing apparatus 10 than the detection area of the first human sensor 28 as shown by the area N in FIG. 10 is recognized, and power is supplied to a part of the image processing apparatus 10 (for example, the main controller 200 and the UI touch panel 216).

  In this way, the first human sensor 28 and the second human sensor 30 are used in combination, and by taking the detection form step by step, the mobile object simply passing and the intention to use the image processing apparatus 10 are obtained. It is possible to distinguish from a certain user.

  On the other hand, when the automatic return mode is disabled (“automatic return release mode”), the first human sensor 28 and the second human sensor 30 do not function when returning from the sleep mode. Therefore, when the user manually operates the saving control button 26 or manually holds the IC card over the IC card reader 217, each device of the image processing apparatus 10 returns from the sleep mode.

  As described above, when returning from the sleep mode, in the case of the automatic return mode, it is used for detection information of the first human sensor 28 and the second human sensor 30, and in the case of the automatic return release mode. The detection information of the first human sensor 28 and the second human sensor 30 is not used, and is restored by manual operation.

  On the other hand, in the transition to the sleep mode, detection information of the first human sensor 28 and the second human sensor 30 is used in any of the automatic return mode and the automatic return cancel mode. This is because if the transition to the sleep mode is left to the user in the automatic return cancellation mode, energy saving performance is impaired by neglecting the operation. Also, in the transition to the sleep mode by the system timer, since priority is usually given to convenience, unnecessary power supply may be performed.

  Here, in the “automatic return mode”, a predetermined time (see time t1 in FIG. 9A) elapses by predicting a case where the user returns once even after deviating from the region N in FIG. After that, the mode is changed to the sleep mode.

  However, in the “automatic return cancellation mode”, since manual return is assumed in the first place, the time t1 is useless and energy saving performance may be impaired.

  Therefore, in the present embodiment, in the “automatic return cancellation mode”, immediately after the second human sensor 30 no longer detects the user, the power supply to each device is cut off and the mode is changed to the sleep mode. I made it.

  Hereinafter, the flow of processing in the “automatic return mode” and the “automatic return cancellation mode” will be described with reference to the timing chart of FIG.

(Control when automatic return mode is enabled)
FIG. 9A is a timing chart of the “automatic return mode” (valid). In addition, the code | symbol of each sentence end shown below shows the temporal position described in FIG. 9 (A).

  During the sleep mode, power is supplied to the first human sensor 28 and no power is supplied to the second human sensor 30 (A1).

  Here, when a moving body is detected by the first human sensor 28, power is supplied to the second human sensor 30. Thereby, the function of the 2nd human sensor 30 becomes effective (A2).

  When the moving body further approaches the image processing apparatus 10 and the second human sensor 30 detects the moving body, power is supplied to the corresponding device (A3).

  Note that the corresponding device refers to, for example, when power is supplied to the UI touch panel 216 or the IC card reader 217 and an operation is performed on these, the other devices (image reading unit 238, image forming unit 240, facsimile) Power may be supplied to the communication control circuit 236 or the like, or power may be supplied to all devices at once.

  When the image processing is completed and the user leaves the image processing apparatus 10, first, the second human sensor 30 is not detected because the user departs from the area N in FIG. 6, and at this point, the timer is started (reset)・ Start) (A4).

  When the predetermined time t1 of the timer elapses, the power supply to the second human sensor 30 and the device is cut off and the sleep state is set (A5).

Thereafter, if the user leaves, the first human sensor 28 may not be detected (A6). Since the first human sensor 28 is constantly supplied with electric power, it may not be detected as indicated by reference numeral A6 and may detect other passing moving objects.
(Control when automatic return mode is disabled)
Next, FIG. 9B is a timing chart of the “automatic return cancellation mode” (invalid). In addition, the code | symbol of each sentence end shown below shows the temporal position described in FIG.9 (B).

  During the sleep mode, power is supplied to the first human sensor 28 and no power is supplied to the second human sensor 30 (B1).

  Here, when a moving body is detected by the first human sensor 28, power is supplied to the second human sensor 30. Thereby, the function of the 2nd human sensor 30 becomes effective (B2).

  The moving object further approaches the image processing apparatus 10, and the second human sensor 30 detects the moving object. However, since the automatic return mode is being canceled, the second person can be supplied without supplying power to the device or the like. The detection information of the sense sensor 30 is invalidated (B3).

  Thereafter, when the user operates the power saving cancel button 26, power is supplied to the device based on this operation (B4).

  Next, when the image processing operation is completed and the user deviates from the region N in FIG. 6, the second human sensor 30 is not detected (B5). While the automatic return mode is being canceled, at this time (that is, at timing B5), the power supply to each device is cut off and the power saving mode is set.

  Thereafter, when the first human sensor 28 no longer detects the moving body, the power supply to the second human sensor 30 is cut off and the sleep mode is completely set (B6).

  In the present embodiment, when the “automatic return mode” is selected by the setting, the first human sensor 28 and the second human sensor 30 are not used when returning from the power saving mode. Even when the power saving control button 26 is restored, when the transition to the power saving mode is made, a predetermined time (time width of the sensor timer in FIG. 9A) is detected after the moving object is not detected by the second human sensor 30. t1) The program is executed after the elapse of time.

  However, in the case of the “automatic return mode” described above, if the power saving control button 26 is used to return, the transition to the power saving mode is performed immediately after the second human sensor 30 does not detect the moving body when the mode is changed to the power saving mode. You may do it.
