  • Scrolling apparatus, scrolling method, and computer-readable medium
    Patent number: 10209875
    Abstract: An electronic apparatus includes a display that displays a content, and a detector that detects contactless proximity of an object to the display and contact of the object to the display. While the content scrolls on the display at gradually decreasing speeds, when the contactless proximity of the object to the display is detected and the contact of the object to the display is not detected, a scrolling speed of the content changes from the gradually decreasing speeds to a constant speed, which is faster than being stopped. After the scrolling speed of the content has changed to the constant speed, while the contactless proximity of the object to the display is detected and the contact of the object to the display is not detected, the content scrolls on the display at the constant speed.

  • Image forming apparatus
    Patent number: 10185239
    Abstract: An exposing unit forms a latent-image electric potential on each photosensitive drum. A detecting toner image of each color is transferred to an intermediate transfer belt using a first potential difference between a latent-image electric potential and the potential of an intermediate transfer belt at each primary transfer portion. When the polarity of voltage to be applied from a transfer power source to a secondary transfer roller is to be switched to an opposite polarity while the detecting toner image of each color is passing through each primary transfer portion, the absolute value of a second potential difference between the potential of the intermediate transfer belt and the background electrical potential of each photosensitive drum is made equal to or greater than the absolute value of the first potential difference by a control unit.
