Abstract: An information processing apparatus comprises a controller configured to execute periodically acquiring relative speed between two vehicles which are traveling on a same road; and performing predetermined processing in a case where a number of times that polarity of the relative speed is inverted in a first period exceeds a first threshold.

Abstract: A component feeder includes: a component housing that stores a plurality of components; a plurality of orientation adjusters that adjusts an orientation of the components housed in the component housing; and a first hardware processor that controls driving of the plurality of orientation adjusters based on component information related to the components housed in the component housing.

Abstract: A component supply device includes a hopper, a conveyance robot, a pick-up stand, and a discharge stand. A temporary placement position at which the component is temporarily placed on the tray is disposed on a straight line connecting a supply position at which the component is supplied to the conveyance robot in the hopper and a hand-over position at which the component is delivered from the conveyance robot on the discharge stand. The discharge stand includes a posture changer that changes a posture of the component conveyed by the conveyance robot.

Abstract: A developing apparatus includes: a housing that accommodates developer and has a plurality of constituent parts; a vibrator that vibrates parts, which are two or more of the plurality of the constituent parts and to which scattered toner may adhere, as vibrated portions; an adjuster provided for at least one of the vibrated portions and the vibrator so as to adjust and match natural frequencies of the two or more of the vibrated portions; and a hardware processor that controls the vibrator.

Abstract: A developer discharge auxiliary tool, including a supporting section which supports a developing unit, that is provided with a discharge port to discharge developer contained therein, at a predetermined height with the discharge port down in a state in which the discharge port is located on a lateral or lower side of the developing unit.

Abstract: In an image forming apparatus that is provided with a developing unit to develop an electrostatic latent image formed on an image carrier as a toner image, the developing unit is provided with a developer reservoir that is disposed between a supplying roller to feed developer agitated by an agitating member into the developer reservoir and a developing roller to cause the developer in the developer reservoir to adhere onto the latent image on the image carrier so as to be developed as the toner image. A control section controls driving of the supplying roller, independently from driving of the agitating member.
