An image forming apparatus is operable at least in a first power state and in a second power state, in which electric power consumption in the second power state is less than electric power consumption in the first power state. The apparatus includes a detection unit formed by a plurality of elements disposed to detect the temperature of an object, and a control unit configured to control the image forming apparatus in such a way as to shift from the second power state to the first power state based on a detection result obtained by the detection unit at first timing and a detection result obtained by the detection unit at second timing.

Image forming apparatus and image forming apparatus control method

An image forming apparatus measures the distance between the image forming apparatus and an object located in the periphery of the image forming apparatus each predetermined amount of time. Then, whether or not the object is a human is detected on the basis of the measured distance and a moving amount of the object each predetermined amount of time. Furthermore, the image forming apparatus controls the power supply state of the image forming apparatus in accordance with the result of the human detection.

Information processing apparatus that inputs a setting related to a sensitivity of human sensor, control method thereof, and storage medium

An image forming apparatus includes a detection unit that detects a user of the image forming apparatus, a power supply control unit that, when a person approaching the image forming apparatus is detected by the detection unit when the image forming apparatus is in a power saving state where power supply to a function unit included in the image forming apparatus is stopped, activates the function unit while maintaining the display unit in a non-display state, and a display control unit that, when the user of the image forming apparatus instructs the display unit to present display after power is supplied to the function unit by the power supply control unit, changes the display unit to a display state.

Image forming apparatus, method for controlling the same, and recording medium

A human presence sensor unit in which an ultrasonic wave sensor is mounted is fixed to a frame sheet metal of an image forming apparatus with a pedestal interposed therebetween. The pedestal is made of a synthetic resin material, and the frame sheet metal is made of a metal material. As the pedestal and the frame sheet metal are made of different materials, a difference in the acoustic impedance is produced between the pedestal and the frame sheet metal.

Electronic device having substrate mounting sonic wave output element that outputs and receives sonic wave, pedestal to which the substrate is attached made of a nonconductive material, frame to which the pedestal is attached made of a conductive material, and conductive tape or conductive leaf spring which contacts substrate and frame
