Abstract: An electronic device associates coordinates of a virtual space with coordinates of a real space. The electronic device includes an imaging section, a recognition section, a first setting section, and a display controller. The imaging section captures an image or respective images of a hand and a robot in the real space to generate a captured image of the hand and the robot. The recognition section recognizes a gesture represented by a motion of the hand based on the captured image. The first setting section sets the robot in the virtual space based on coordinates of the hand in the virtual space when it is recognized that the gesture corresponds to a first gesture. The display controller controls display of the robot so that the robot is visible to the human eye.

Abstract: A motor control device includes a motor and a motor driver. The motor rotates a conveyance roller that conveys a sheet. The motor driver drives the motor on the basis of a control signal. The motor driver receives from the motor a rotation signal indicating a rotation amount of the motor and performs feedback control on the motor on the basis of the rotation signal and the control signal. The feedback control refers to controlling the motor to make the rotation amount indicated by the rotation signal match a rotation amount specified by the control signal. The motor driver stops the feedback control when determining that a rotation amount of the motor per unit time determined on the basis of the rotation signal has converged to a rotation amount per unit time specified by the control signal.

Abstract: A speed control portion of a motor driving device performs a deceleration control of decelerating a rotation speed of a driving motor based on a first pulse signal for the deceleration control that includes a plurality of pulses whose pulse width corresponds to each commanded speed to the driving motor. A pulse signal output portion generates the first pulse signal and a second pulse signal and outputs the second pulse signal to the speed control portion after outputting the first pulse signal to the speed control portion, wherein the pulse width of the first pulse signal changes by obeying a predetermined rule that corresponds to a deceleration tendency of the rotation speed during the deceleration control, and the second pulse signal does not obey the predetermined rule. When a determination processing portion determines that the second pulse signal is included in an input signal, the deceleration control is ended.

Abstract: A motor controller (58) according to the present invention includes a pulse width detection portion (595), a speed control portion (591), a pulse width storage portion (596), a same pulse detection portion (597), and a stop processing portion (598). The pulse width detection portion detects the pulse widths of pulses included in the pulse signal. The speed control portion performs: an acceleration control of the drive motor; and a deceleration control of the drive motor. The same pulse detection portion detects, from among the pulses included in the pulse signal inputted during the deceleration control, a pulse in which the pulse width detected by the pulse width detection portion is the same pulse width as the pulse width of an earliest pulse stored in the pulse width storage portion. The stop processing portion stops control of a rotation speed of the drive motor performed by the speed control portion.

Abstract: A sheet conveying device includes a conveying roller, a drive motor, a second detection portion, and a control portion. The control portion includes a first drive control portion, a rotation amount calculation portion, and a second drive control portion. When a front end of a sheet member is detected by the second detection portion, the first drive control portion sets driving of the drive motor in a stopped state before the sheet makes contact with the conveying roller. Rotation amount calculation portion performs a process of calculating a rotation amount of the conveying roller after the sheet member conveyed from upstream in the conveying direction of the sheet member makes contact with the conveying roller. Second drive control portion starts driving of the drive motor at a timing in accordance with the rotation amount of the conveying roller calculated by the rotation amount calculation portion.

Abstract: In sheet conveying device, first pair of rollers, driven by first driving motor, conveys sheet on conveyance path that passes image forming portion that forms image on the sheet. Second pair of rollers, driven by second driving motor, conveys the sheet on the conveyance path together with the first pair of rollers. Speed difference calculating portion calculates speed difference between speed related to sheet conveyance speed of the first pair of rollers and speed related to sheet conveyance speed of the second pair of rollers. The motor control portion determines target speeds respectively for the first driving motor and the second driving motor based on the speed difference calculated by the speed difference calculating portion, and performs control during non-image formation period so that driving speeds of the first driving motor and the second driving motor respectively become the target speeds.
