    摘要: A sheet feeder includes a loading surface, a supply roller configured to feed recording sheets loaded on the loading surface, an overload prevention member disposed upstream from the supply roller in a sheet feed direction, and a movable member disposed downstream from the overload prevention member in the sheet feed direction. The overload prevention member includes a restriction surface configured to be moved between a first position and a second position. The movable member is configured to be moved from a third position to a fourth position by being pushed by leading ends of the recording sheets. The movable member and the overload prevention member are configured to interlock each other such that, when the movable member is in the third position, the restriction surface is in the first position, and when the movable member is in the fourth position, the restriction surface is in the second position.

    摘要: An image forming apparatus includes an apparatus body, a recording head, head tanks, main tanks, liquid feed pumps, a first driving source, a drive control unit, and a drive switching assembly. The drive switching assembly includes a second driving source, a cam, a slider member, a switching gear, switching position detected portions, and a detector. The detected portions are disposed at the cam so as to correspond to switching positions of the liquid feed pumps. One of the detected portions has a greater width in a rotation direction of the cam than any other detected portion. When a time from when the detector detects one of the detected portions to when the detector detects another one of the detected portions is shorter than a threshold value, the drive control unit determines, as a home position, a position of the cam on detection of the another one with the detector.

    摘要: A sheet supplying unit that supplies sheets includes a sheet accommodation tray that accommodates the sheets in a stacked state, the sheets including a first sheet which is an uppermost sheet in the stack of the sheets and a second sheet which is immediately below the first sheet; a pick-up roller that conveys the sheets in a sheet conveying direction; a detection sensor that detects passage of the sheets and is disposed downstream of the pick-up roller in the sheet conveying direction; and a control unit that controls operations of the pick-up roller in accordance with outputs from the detection sensor. The control unit includes a driving section that drives the pick-up roller to start conveying the second sheet when the detection sensor detects a trailing edge of the first sheet, if the second sheet is to be fed; a suspending section that temporarily stops driving the pick-up roller for a time period α-β when the detection sensor detects a leading edge of the second sheet, α being a predetermined time period, and β being a time period from a timing when the detection sensor detects the trailing edge of the first sheet to a timing when the detection sensor detects the leading edge of the second sheet; and a resuming section that resumes driving the pick-up roller to convey the second sheet after suspending for the time period α-β.
