Description

  The present invention relates to an electronic device, an apparatus, and a control method.

  In recent years, development of technology for saving power consumption of electronic devices has been promoted in response to a request to save energy.

  The hardware configuration included in the image forming apparatus 100 has been described above. Next, functional units executed by each hardware of the image forming apparatus 100 will be described with reference to FIG. FIG. 3 is a software block diagram of the image forming apparatus 100 according to each embodiment of the present invention.

  A main body 200 of the image forming apparatus 100 includes a power control unit 210 and an image forming unit 220. The power control unit 210 is a unit that controls power supply of the image forming apparatus 100, and supplies power to the image forming unit 220 and the operation unit 300.

An adjustment unit 380 is included.

  The removal determination unit 310 is a unit that determines whether the operation unit 300 has been removed from the main body 200. The determination of removal can be made based on, for example, the presence or absence of power supply from the main body power supply 211.

  The tilt detection unit 320 is a unit that detects the tilt of the operation unit 300 detached from the main body 200 based on the output of the posture sensor 305a. When the inclination of the operation unit 300 is equal to or greater than the threshold, it is determined that the user is operating with the operation unit 300 removed, and the operation of the operation unit 300 can be controlled.

  Note that the determination as to whether or not the user is using the operation unit 300 may be made based on a change in inclination with time. For example, when there is no change in inclination for a long time, the user can determine that the operation unit 300 is not being used.

  The threshold value determination unit 340 is a unit that compares the inclination amount calculated by the inclination amount calculation unit 330 with a preset threshold value and determines whether the operation unit 300 is supplied with power or cut off. For example, if the calculated tilt amount is substantially horizontal, it can be determined that the probability that the user is using the operation unit 300 is low. On the other hand, when the calculated inclination amount is larger than the threshold value, it can be determined that the probability that the user is using the operation unit 300 is high. It should be noted that an arbitrary value can be set by the user as the threshold value serving as a determination criterion.

For example, when the operation unit 300 is attached to the main body 200, the operation unit 300 receives supply of power from the main body power supply 211.

  Further, when the operation unit 300 is detached from the main body 200, the posture sensor 305 a detects the inclination of the operation unit 300 to determine the usage status of the operation unit 300. Further, when the operation unit 300 is detached from the main body 200 and the inclination has not changed over a certain period of time, the power supply is cut off, so that the consumption of the operation unit power supply 303 can be saved.

  The display unit 370 is means for displaying information to be provided to the user on the screen 306. The display unit 370 can control the turning on / off of the backlight, the luminance, the color, and the like, and the display unit adjustment unit 380 can adjust these setting items.

  The display unit adjustment unit 380 is a unit that adjusts the display of the screen 306, and includes a backlight control unit 381, a luminance control unit 382, and a color control unit 383. Since the operation unit 300 removed from the main body 200 has limited power resources, the consumption of the operation unit power supply 303 can be saved by controlling the turning on / off of the backlight according to the use state of the user. Can do.

  In addition, the brightness and color of the screen 306 change the way the user feels depending on the brightness of the surroundings, and affect the ease of viewing and eye fatigue. Therefore, a comfortable operating environment can be provided by adjusting the luminance and color of the screen 306 according to the brightness detected by the illuminance detection unit 350.

  Thereafter, in step S <b> 1003, when the user removes the operation unit 300 from the main body 200, the removal determination unit 310 determines a connection state between the operation unit 300 and the main body 200. When the operation unit 300 is detached from the main body 200, the operation unit power control unit 360 switches the power supply source of the operation unit 300 to the operation unit power source 303 in step S1004. Note that the operation unit power supply 303 can always charge the power generated by the solar cell even when power is supplied.

  In step S1005, the tilt detection unit 320 detects the tilt of the operation unit 300 based on the output of the attitude sensor 305a. In step S1006, whether the tilt amount of the operation unit 300 is equal to or greater than a preset threshold value. Determine whether or not. If the amount of inclination is smaller than the threshold (NO), the process returns to step S1005 and the detection of the inclination is repeated.

  If it is determined in step S4006 that the amount of inclination is smaller than the threshold (NO), the process proceeds to step S4008. In this case, as in step S2008 in the second embodiment, the operation unit 300 is removed from the main body 200, but it is considered that the probability that the user is using the operation unit 300 is low. Therefore, in step S4008, processing for turning off the backlight of the screen 306 of the operation unit 300 is performed.
