  • Publication number: 20240034578
    Abstract: A sheet feeder includes a sheet loading tray, an air blower, a side air blower, and processing circuitry. The sheet loading tray loads sheets. The air blower blows air to the sheets to float and separate the sheets. The side air blower blows air to the sheets to separate the sheets. The processing circuitry controls a tray elevator to rise the sheet loading tray to move the sheets to an upper limit position, after a predetermined time has elapsed from a time when the sheets are loaded on the sheet loading tray. The processing circuitry causes the air blower and the side air blower to blow air to the sheets to perform sheet separation and controls the tray elevator to lower the sheet loading tray to a position at which an intermediate remaining-sheet sensor is disposed, after the sheet separation ends.

  • Publication number: 20230159289
    Abstract: A sheet feeding apparatus includes a sheet stacker, an air blower, a suction feeder, a lifting mechanism, an elevation detection sensor, an elevation detection sensor, a feed detection sensor, and processing circuitry. The air blower blows air to float an uppermost sheet of sheets stacked on the sheet stacker. The processing circuitry drives the lifting mechanism such that the sheet stacker is lifted by an elevation amount determined based on a sheet thickness of the sheets stacked on the sheet stacker, each time a sheet is detected when a number of sheets detected is smaller than a threshold number of sheets, and stops lifting of the sheet stacker until a sheet is not detected when the number of sheets reaches the threshold number of sheets, while repeatedly feeding the uppermost sheet and counting the number of sheets.

  • Patent number: 11597616
    Abstract: A feeding device includes a loading portion, a lifting mechanism, a conveying unit, a sheet detector, a near-end detector, and process circuitry. The loading portion stacks a plurality of sheets. The lifting mechanism lifts the loading portion. The conveying unit conveys the sheets on the loading portion. The sheet detector detects presence or absence of the sheets on the loading portion at a specified height position. The sheet count detector detects a number of sheets conveyed by the conveying unit. The near-end detector detects a near-end state in which a stack height of the sheets on the loading portion is a specified value or less. The process circuitry controls the lifting mechanism based on a detection result of the sheet detector before the near-end state is detected, and controls the lifting mechanism based on a detection result of the sheet count detector after the near-end state is detected.

  • Patent number: 11097636
    Abstract: A fuel cell vehicle includes a fuel cell, an oxygen-containing gas supply apparatus, and an ECU. A pump of the oxygen-containing gas supply apparatus is a shaft floating type air pump having a rotatable element. The rotatable element floats from a wall around the rotatable element, as a result of rotation of the rotatable element. The ECU includes a travel permission determination instruction unit. The travel permission determination instruction unit determines whether or not a predetermined condition indicative of a floating state of the rotatable element is satisfied, and if the predetermined condition is satisfied, permits traveling of the fuel cell vehicle, and if the predetermined condition is not satisfied, restricts traveling of the fuel cell vehicle.

  • Patent number: 10635241
    Abstract: [Problem] To detect touch coordinates, without detection errors and without using a special pen, on a substrate such as a touch panel. [Solution] This coordinate detection method comprises: calculating a ratio between the short-term average (STA) and long-term average (LTA) of output signals from at least three vibration detectors installed apart from each other at predetermined distances on a substrate which has a uniform thickness and is made from a homogeneous material that allows the propagation speeds of oscillating waves to be constant; calculating, as arrival times, the times at which the STA/LTA ratio of the three vibration detectors by oscillating waves generated by touching the substrate exceeds a predetermined threshold value; and calculating touch position coordinates on the basis of each of the arrival times, the propagation speed of the oscillating waves, and the distances at which the three vibration detectors are spaced apart from each other.

  • Patent number: 10017342
    Abstract: A paper sheet conveyance device includes a plurality of conveyance members and conveys a paper sheet while performing temporary stop of conveying and then restart of conveying. Two paper sheets sequential in a conveyance direction stop together in a state of the temporary stop, driving a first transfer member to which a preceding first paper sheet that is one of the two paper sheets is opposed and a second conveyance member to which a following second paper sheet that is the other paper sheet is opposed is stopped and restarted synchronously for the temporary stop and the restart. A stop position information acquisition unit acquires information on a position on the conveyance path at which the second paper sheet stops in the state of the temporary stop, and a timing for stopping the conveying after the conveying is restarted is controlled according to the acquired information.
