  • Patent number: 11269277
    Abstract: According to an embodiment, an image forming apparatus includes a motor of which driving current value changes according to a load, an image forming unit, a measuring unit, and a setting unit. The measuring unit forms an image on a medium by using a rotation body rotated by a motor. The measuring unit measures the driving current value of the motor. When a rotation speed of the motor is set to a first speed, the setting unit continues to set the first speed if the driving current value measured by the measuring unit falls within a first range. The setting unit sets a second speed lower than the first speed as the rotation speed if the driving current value measured by the measuring unit falls within a second range higher than the first range.

  • Patent number: 10336117
    Abstract: An image erasing apparatus according to an embodiment includes a sheet supply portion that supplies a sheet and an ejector. A first conveying path conveys the sheet from the sheet supply portion toward the ejector. A reader arranged on the first conveying path reads an image on the sheet. A second conveying path branches from the first conveying path at a downstream of the reader on the first conveying path and merges with the first conveying path at an upstream of the reader on the first conveying path. An erasing unit is arranged on the second conveying path. A conveying path changing portion is arranged at a branching portion. An operating portion receives a setup of the processing to the sheet. A controller changes a conveying path of the sheet in accordance with the setup received by the operating portion before the sheet is supplied from the sheet supply portion.

  • Patent number: 10252876
    Abstract: A sheet processing apparatus according to an embodiment includes a first tray that holds a sheet transported to the sheet processing apparatus in a sheet transport direction. A second tray is provided below the first tray and holds the sheet moved from the first tray. A first member, when the sheet is moved from the first tray to the second tray, rotates about a turning shaft, and presses a first portion of the sheet toward the second tray by making a pressing portion of the first member contact with the first portion. A second member, when the sheet is moved from the first tray to the second tray, protrudes toward the second tray at a position between the turning shaft and the pressing portion of the first member, and presses a second portion of the sheet toward the second tray, the second portion being located downstream of the first portion.
