  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 first power supply unit 248 and the second power supply unit 250. Although not shown, the second power supply unit 250 is a wiring that branches from the wiring on the downstream side of the main switch 246 and receives power from the commercial power supply 242.

  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) is performed.

  On the other hand, a first sub power switch 256 (hereinafter also referred to as “SW-1”) is interposed in a power line 254 (ground side) 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 (power consumption is 0 state).

  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 are selectively supplied with 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 a 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 also referred to as “SW-5”). Via the UI touch panel 216 (including the backlight unit 216BL). Note that power may be supplied from the power-saving monitoring control unit 24 to the original functions of the UI touch panel 216 (functions excluding 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 based on the 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. In addition, the power switches 268 to 276 may be arranged not in the power supply apparatus 202 but in each device to which power is supplied.

  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.

(Supervisory control for state transition of image processing device)
Here, the main controller 200 according to the first embodiment may partially stop its function so that the necessary minimum power consumption is achieved. Alternatively, the power supply may be stopped including most of the main controller 200. These may be collectively referred to as “sleep mode (power saving mode)” (see FIG. 5).

  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 predetermined time elapses after the system timer is 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.

  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.

  By the way, in the monitoring during the power saving, for example, a print request or the like from the communication line detection unit or a FAX reception request from the FAX line detection unit, the device that is in the sleep state (power saving), In the power saving monitoring control unit 24, 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 first power supply control circuit 252 are provided. It is assumed that power is supplied by controlling the sub power switch 276 of No. 5.

(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. By operating the power saving control button 26, the power saving can be canceled. 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.

  Here, in order to monitor in the sleep mode, it is preferable to supply the power saving control button 26 and each detection unit to the power saving control button 26 and each detection unit in addition to the power saving monitoring control unit 24 while the power is being saved. 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. In this case, in the UI touch panel 216, it is preferable that the backlight unit 216BL is turned off or the illuminance is reduced more than usual in order to ensure energy saving even a little.

  For example, the specific period is distinguished as an awake mode (awk) as a tentative name in FIG. 5, but this mode is not particularly essential.

  Although not shown in FIG. 5, the sleep mode (other than the awake mode) includes an “all-off mode” that requires a CPU initialization process, a process clock stabilization wait, and the like when the main controller 200 is activated, When the controller 200 is activated, the controller 200 may be classified as a “pre-off mode” that does not require a CPU initialization process or a waiting time for stabilization of a processing clock.

  The difference between the “all-off mode” and the “pre-off mode” is different in the return time until the main controller 200 starts up. That is, the rise time toff from the all-off mode is longer than the rise time tpre from the preoff mode (toff> tpre).

(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, the first human sensor 28 and the second human sensor 30 are installed in the power saving monitoring control unit 24. In the sleep mode, the human sensor detects the user before pressing the power saving cancel button. The power supply was restarted early so that users could use it quickly. Although the power saving control button 26, the first human sensor 28, and the second human sensor 30 are used in combination, all the monitoring is performed only by the first human sensor 28 and the second human sensor 30. It is also possible to perform.

  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 feelings”, which are proper nouns according to the first embodiment, and are at least detected (detected) by humans. ) As long as it can be done, 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 first 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 first 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 is wide. Further, in order to sense the movement of the moving body, 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 first embodiment naturally includes complete stillness such as a still image taken with a still camera or the like. For example, a person stops in front of the image processing apparatus 10 for the purpose of operation. Including that. 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. .

  Accordingly, the sensitivity of the first human sensor 28 is not adjusted by adjusting the sensitivity of the first human sensor 28, but the sensitivity is adjusted relatively roughly and standardly. You may make it depend on a state. That is, when the first human sensor 28 outputs one of the binary signals (for example, a high level signal), it indicates that the person is moving, and the second first human sensor. A case where a person exists in the 28 detection regions and another one of the binary signals (for example, a low level signal) is output may be set to be stationary.

  The specification of the first human sensor 28 according to the first embodiment is to detect the movement of the moving body around the image processing apparatus 10 (for example, in a 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 first 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 first embodiment, the maximum detection range (for example, the first region F and the second region N in FIG. 6) is set by the first human sensor 28 and the second human sensor 30. 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 serves as a remote mobile body detection means. It has a function. 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 a proximity moving body detection unit. As a function.

  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 2-3 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 0.3 to 1.0 m.

(Sensor power supply control)
In the first 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, regarding the interruption of the power supply of the second human sensor 30, the timer function provided in the power saving monitoring control unit 24 is used in addition to the moving body detection status of the first human sensor 28. It is like that. 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. The form which is made to a certain distance (refer the trend (C pattern) of C line arrow of FIG. 6).

  In the first embodiment, based on the detection information by the first human sensor 28, the detection information by the first human sensor 28, and the timing information of the sensor timer, the trend (the A pattern shown in FIG. The power supply timing and power supply cutoff timing of the second human sensor 30 in accordance with the movement pattern of the person based on the C pattern are controlled.

(Detection accuracy adjustment of the second human sensor 30)
Here, the moving body detection of the second human sensor 30 in the first embodiment affects the subsequent power supply control. For example, as shown in pattern B of FIG. 6, when traversing the detection area of the second human sensor 30 (passing through the vicinity of the image processing apparatus 10), the power saving monitoring control unit 24 activates at least the main controller 200. Activate the instruction to

  In order to distinguish between the case where the vicinity of the image processing apparatus 10 is passed and the case where the image processing apparatus 10 is actually used, a time when the moving body crosses the second human sensor 30 is predicted in advance. The detection status of the human sensor 30 is confirmed again during the time.

  That is, if the moving object is still detected by the second human sensor 30 by the second confirmation, the moving object recognizes that it is a user who intends to use the image processing apparatus 10, For example, a transition is made to a state in which power is supplied to some devices such as an awake mode (see FIG. 5).

  On the other hand, if the second human sensor 30 no longer detects the moving body due to the confirmation again, the moving body recognizes that the moving body has passed through the vicinity of the image processing apparatus 10, for example, The power supply to the main controller 200 is cut off.

  The time for the moving body to cross the second human sensor 30 is, for example, as an initial setting when the detection distance of the second human sensor 30 passes through the image processing apparatus 10 around 0.3 m (30 cm). The time is set. This is because power is not supplied to the main controller 200 or the like every time the moving body passes, but power is not supplied until the card is held over the IC card reader 217 or until the operation of the UI touch panel 216 is started. It is set on the condition that it is supplied and standing up.

(Rising control from sleep mode)
Here, as described above, whether the main controller 200 belongs to the “all-off mode” or the “pre-off mode” even in the same sleep mode depends on the situation of the previous image processing apparatus 10. .

  For example, when processing such as copying ends and the system timer is activated or the power saving control button 26 is operated, the “pre-off mode” is set (rise time tpre).

  On the other hand, in the “pre-off mode”, when the state in which the image processing apparatus 10 is not used continues for a predetermined time, the “all-off mode” is set (rise time toff).

  In the “pre-off mode”, the rise time until the main controller 200 can function normally is tpre, and in the “pre-off mode”, the time until the main controller 200 can function normally is toff, Both have a relationship of toff> tpre.

  Here, when the user gradually approaches the image processing apparatus 10, electric power is supplied to the second human sensor 30 when entering the detection region of the first human sensor 28, and the second human sensor 30. The user detection state by the human sensor 30 is started.

At this time, if the detection area (longest detection distance) of the second human sensor 30 is fixed, the following situations can be considered in each of the “all-off mode” and “pre-off mode”.
(Situation a) In the “off-off mode”, when the user is detected by the second human sensor 30 and the start-up process of the main controller 200 is started, the approaching user operates the UI touch pan 216. In addition, the startup process is not completed, and it is necessary to wait for the user's operation.
(Situation b) In the “pre-off mode”, although the moving object is detected by the second human sensor 30 and the start-up process of the main controller 200 is started, the moving object is not a user and is merely a user. If it is a person who passes, power is supplied to the main controller 200 and the like unnecessarily.

  In the situation a, the longest detection distance of the second human sensor 30 may be increased to an extent corresponding to the time required for the startup process of the main controller 200.

  On the other hand, in the situation b, the longest detection distance of the second human sensor 30 may be shortened to such an extent that a passing area is excluded.

  For example, in the case of a reflective sensor, the longest detection distance can be adjusted by adjusting the reference voltage of the detection distance detection comparator included in the reflective sensor. For example, when the reference voltage is 1.5 V, the longest detection distance is relatively short (narrow), and when the reference voltage is 0.8 V, the longest detection distance is relatively long (wide).

  However, there is a difference in the optimum longest detection distance for each of the situation a and the situation b, and the situation a and the situation b have a trade-off relationship.

  Therefore, in the first embodiment, there is a correlation between the mode type of the sleep mode and the longest detection distance of the second human sensor 30, and the longest detection distance of the second human sensor 30. Was adjusted and controlled.

  FIG. 7A shows the case where the longest detection distance Lt1 of the second detection sensor 30 is short, and FIG. 7B shows the case where the longest detection distance Lt2 of the second detection sensor 30 is long. It is a side view.

  For example, FIG. 7A is applied when the sleep mode is the “pre-off mode”, and after detecting that the user is approaching at the longest detection distance Lt 1, the user reaches the image processing apparatus 10 at the maximum. The time t1 until approaching is longer than the rise time tpre of the “pre-off mode” and shorter than the rise time toff of the “all-off mode” (toff> t1> tpre). Therefore, it is possible to start up the main controller 200 of the image processing apparatus 10 until the user approaches the image processing apparatus 10 and operates the UI touch panel 216 and the like, and the convenience is maintained. However, since the longest detection distance is shortened, false detection is reduced and energy saving is improved as compared with the case where the longest detection distance is long.

  On the other hand, FIG. 7B is applied when the sleep mode is the “all-off mode”, and the user detects that the user is approaching at the longest detection distance Lt2, and then the user connects to the image processing apparatus 10. The time t2 until the closest approach is longer than the rise time tpre of the “pre-off mode” and the rise time toff of the “all-off mode” (t2> toff> tpre). Therefore, it is possible to start up the main controller 200 of the image processing apparatus 10 until the user operates the UI touch panel 216 or the like closest to the image processing apparatus 10, and the longest detection distance is Although there is a possibility of erroneous detection as compared with the case where the distance is short, the convenience can be improved as compared with the case where the longest detection distance is short.

  The times t1 and t2 depend on the walking speed of the user. Generally, the walking speed in an office or the like may be used as a reference. For example, an adult walking speed of 3 to 5 km / hour is a guideline. However, the present invention is not limited to this numerical value range, and may be set according to an experimental result at the place where the image processing apparatus 10 is installed.

  In addition, as an example, when the time required for walking from a real estate property to the nearest station is described, as the “time required for walking” according to the display rules of the Real Estate Fair Trade Council (as of 2011), 1 minute = 80 m (4 .8km / hour) is set as a standard.

  The operation of the first embodiment will be described below.

(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 has not been processed, the operation state is the sleep mode. In the first embodiment, power is supplied only to the power saving monitoring control unit 24.

  Here, when there is a start trigger (detection of a start trigger or operation of the power saving control button 26, etc.), the operating state transitions to the warm-up mode.

  It should be noted that after triggering this startup trigger, the sleep mode may still be defined and only the UI touch panel 216 may be activated on the premise of power supply to the main controller 200, or the main controller 200 and the UI touch panel 216 may be activated. Since the power supply amount is increased more than the power supply only by the power saving monitoring control unit 24, the awake mode “awk” (wake-up mode) may be defined as a temporary name (in the transition diagram of FIG. 5, (See parentheses [] in the sleep mode range). When there is an operation input (key input) on the UI touch panel 216 or the like in this awake mode, the operation state transitions to the warm-up mode.

  The startup trigger mainly includes a signal, information, and the like based on the detection result by the second human sensor 30. Note that a power-saving canceling operation by the operator may be used as a startup trigger.

  In the warm-up mode, the image processing apparatus 10 is brought into a processable state quickly, so that the maximum power consumption in each mode is achieved. For example, by using an IH heater as a heater in the fixing unit, a halogen lamp is used. The warm-up mode time is relatively shorter than the heater used.

  When the warm-up operation in the warm-up mode is completed, the image processing apparatus 10 transitions to the standby mode.

  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 transits to the running mode again, and when the falling trigger is detected or a predetermined time elapses, the mode transits to the sleep mode.

  The falling trigger includes a signal, information, and the like based on the detection result by the second human sensor 30. A system timer may be used in combination.

  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.

  Here, each device that operates by receiving the supply of power can immediately execute each process by shifting from the sleep mode in FIG. 5 to the standby mode through the awake mode and the warm-up mode.

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

(Rising control from sleep mode)
The sleep mode includes an “all-off mode” and a “pre-off mode”. In the “pre-off mode”, the rise time until the main controller 200 can function normally is tpre, and in the “pre-off mode”, the main controller Assuming that the time until 200 can function normally is toff, there is a relationship of toff> tpre.

  On the other hand, when the user gradually approaches the image processing apparatus 10, power is supplied to the second human sensor 30 when entering the detection area of the first human sensor 28, and the second human sensor 30. A detection state of a moving body (such as a user) by the human sensor 30 is started.

  In the first embodiment, in such moving body detection, the detection area (longest detection distance) of the second human sensor 30 is adjusted according to the type of sleep mode.

  As described above, this adjustment is “situation a (the longest detection distance of the second human sensor 30 may be increased to an extent corresponding to the time required for the startup process of the main controller 200)” and “ The control is performed in consideration of the situation b (the longest detection distance of the second human sensor 30 may be shortened to such an extent that the passing area is excluded).

  FIG. 8 is a flowchart for the second human sensor 30 detection distance adjustment control in the sleep mode according to the first embodiment.

  When the sleep mode is entered, first, in step 300, power supply cutoff processing of various devices is executed, and in the next step 302, the type of sleep mode (all-off mode or pre-off mode) is determined.

  If it is determined in step 302 that the pre-off mode is selected, the sleep state is shallow (for example, power is supplied to all of the main controller 200) and the rise time is relatively fast. The longest detection distance of the second human sensor 30 is set to Lt1 (see FIG. 7A), and then the process proceeds to step 306, where the first human sensor 28 and the second human sensor 30 are divided. Enables the detection of the error, and proceeds to step 308. In step 308, the sleep mode of the pre-off mode is entered, and this routine ends.

  On the other hand, if the all-off mode is determined in step 302, the sleep state is deep (for example, power is supplied to only a part of the monitoring control units 24 of the main controller 200), and the rise time is Since it is relatively slow, the routine proceeds to step 310, where the longest detection distance of the second human sensor 30 is set to Lt2 (see FIG. 7B), and then the routine proceeds to step 312 to enter the first human sensor. 28, the interrupt detection of the second human sensor 30 is validated, and the process proceeds to step 314. In step 314, the sleep mode of the all-off mode is entered, and this routine ends.

  By changing the longest detection distance of the second human sensor 30 according to the type of the sleep mode, the main controller 200 can be surely connected until the user starts to operate the UI touch panel 216 of the image processing apparatus 10. Since it stands up, it is possible to achieve both the energy saving of shortening the longest detection distance as much as possible and the convenience of giving priority to the user's operation.

[Second Embodiment]
The second embodiment will be described below. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description of the configuration is omitted.

  In the first embodiment described above, when the longest detection distance of the second human sensor 30 is shortened, the time t1 until the user comes closest to the image processing apparatus 10, and the second human sensor 30 The user sets a time t2 until the closest approach to the image processing apparatus 10 when the longest detection distance is increased, and either time (t1 or t1) depending on the type of sleep mode (“pre-off mode” or “all-off mode”) t2) is set.

  On the other hand, in the second embodiment, when the longest detection distance of the second human sensor 30 is shortened, the time t1 until the user approaches the image processing apparatus 10 and the second person A time t2 until the user approaches the image processing apparatus 10 when the longest detection distance of the sensation sensor 30 is increased is set, and the power saving control button 26 when starting from the sleep mode regardless of the type of the sleep mode. One of the times (t1 or t2) is set according to the operation state.

  FIG. 9 is a flowchart showing a longest detection distance adjustment control routine during power supply according to the second embodiment.

  This routine is started when it is determined that the second human sensor 30 starts up from the sleep mode. First, in step 330, the first human sensor 28 and the second human sensor 30 are allocated. Detection is disabled, and the process proceeds to step 332.

  In step 332, a power supply process is executed to the main controller 200 and the UI touch panel 216 based on the user detection by the second human sensor 30. Note that, for example, when there is a print instruction from the outside (PC 21 or the like shown in FIG. 1), power is supplied to the image forming unit 240, but the control is separate from this routine (not shown).

  In the next step 334, it is determined whether or not the return control button 26 has been operated before the UI touch panel 216 is completely raised.

  When a negative determination is made in step 334, the process proceeds to step 336, and it is determined whether or not the UI touch panel 216 has been operated after a predetermined time has elapsed since the user was detected. If a negative determination is made in step 336, it is determined that the detection by the human sensor 30 is a false detection (the detection itself is appropriate, but a simple moving body, etc.), and the process proceeds to step 338 and the second The longest detection distance of the human sensor 30 is set to Lt1 (see FIG. 7A), and this routine ends. If the determination in step 336 is affirmative, the user has been properly detected, so the longest detection distance of the second human sensor 30 is determined to be appropriate, and this routine ends.

  On the other hand, if the determination in step 334 is affirmative, it is determined that the longest detection distance of the second human sensor 30 is short (including the case where the user's walking speed is faster than the reference) and lacks convenience. Then, the process proceeds to step 340, where the longest detection distance of the second human sensor 30 is set to Lt2 (see FIG. 7B), and this routine ends.

  The longest detection distance of the second human sensor 30 is based on a relatively short distance with the main focus on energy saving, and the operation of the return control button 26 after detecting the user by the second human sensor 30 If the UI touch panel 216 does not stand up until the user tries to operate the UI touch panel 216, the longest detection distance is increased to improve convenience.

[Third Embodiment]
The third embodiment is a combination of the first embodiment and the second embodiment described above. That is, in the third embodiment, the following configurations are combined.
(Configuration 1) The basic specification is the first embodiment (one time (t1, t2) is selected according to the type of sleep mode and the longest detection distances Lt1, Lt2 are determined).
(Configuration 2) Under the basic specifications, the second embodiment (selects any time (t1, t2) according to the operation status of the power saving control button 26, etc., and determines the longest detection distances Lt1, Lt2. Apply the control of.
(Configuration 3) At the time of standing from the pre-off mode, the time t1 is corrected by ± Δ according to the operation state of the power saving control button 26 and the like to obtain the longest detection distance L (t1 ± Δ).
(Configuration 4) At the time of start-up from the all-off mode, the time t2 is corrected by ± Δ according to the operation state of the power saving control button 26 and the like, and the longest detection distance L (t2 ± Δ) is obtained. To do.

  In other words, in the pre-off mode and the all-off mode, the longest detection distances Lt1 and Lt2 serving as the reference are corrected.

  FIG. 10 is a flowchart showing a longest detection distance correction control routine according to the third embodiment.

  This routine is started when it is determined that the second human sensor 30 rises from the sleep mode. First, in step 350, the first human sensor 28 and the second human sensor 30 are allocated. And the process proceeds to step 352.

  In step 352, a power supply process is executed to the main controller 200 and the UI touch panel 216 based on the user detection by the second human sensor 30.

  In the next step 354, it is determined whether or not the return control button 26 has been operated before the UI touch panel 216 is completely raised.

  If a negative determination is made in step 354, the process proceeds to step 356, and it is determined whether or not the UI touch panel 216 has been operated after a predetermined time has elapsed since the user was detected. If a negative determination is made in step 356, it is determined that the longest detection distance of the second human sensor 30 is long, and the process proceeds to step 358 to determine the state of the sleep mode before the current startup process.

  After it is determined that the longest detection distance of the second human sensor 30 is long, if it is determined in step 358 that the sleep mode is the pre-off mode (shallow sleep), the process proceeds to step 360, where the second person The longest detection distance of the sense sensor 30 is corrected to minus (−Δ) by Lt1 (see FIG. 7A), and this routine ends. If it is determined in step 358 that the sleep mode is the all-off mode (deep sleep), the process proceeds to step 362, and the longest detection distance of the second human sensor 30 is decremented by Lt2 (see FIG. 7B). Correction (−Δ) is made, and this routine ends. If the determination in step 356 is affirmative, the user has been properly detected, so the longest detection distance of the second human sensor 30 is determined to be appropriate, and this routine ends without correction.

  On the other hand, if an affirmative determination is made in step 354, it is determined that the longest detection distance of the second human sensor 30 is short, and the process proceeds to step 364 to determine the state of the sleep mode before the current startup process. .

  If it is determined that the longest detection distance of the second human sensor 30 is short and the sleep mode is determined to be the pre-off mode (shallow sleep) in step 364, the process proceeds to step 366, where the second person The longest detection distance of the sensation sensor 30 is positively corrected (+ Δ) by Lt1 (see FIG. 7A), and this routine ends. If it is determined in step 364 that the sleep mode is the all-off mode (deep sleep), the process proceeds to step 368, and the longest detection distance of the second human sensor 30 is increased by Lt2 (see FIG. 7B). Correction (+ Δ) is made, and this routine ends.

  Correction (fine adjustment) is possible in each of the longest detection distances Lt1 and Lt2 of the second human sensor 30 set according to the type of sleep mode.
