A sheet feeding device includes: a sheet storage that stores a plurality of sheets; a conveyer that conveys, in a sheet conveyance direction, sheets stored inside the sheet storage; a driver that drives the conveyer in such a manner that a conveyance speed of the sheet is switchable between two or more speeds; a corrector that corrects inclination of the sheet more on a downstream side in the sheet conveyance direction than the conveyer is; a first sheet detector that detects a sheet positioned at a first predetermined position between the conveyer and the corrector; and a hardware processor that controls the driver to change a conveyance speed of the sheet conveyed by the conveyer in accordance with a detection result of the first sheet detector.

Sheet feeding device and image forming device

An aspect of the present invention includes: a sheet storage unit configured to store sheets; an air blowing unit configured to blow air; a duct configured as a flow passage to an air blowing outlet for blowing air sent from the air blowing unit toward the front end of an upper part of a sheet bundle stored in the sheet storage unit; a suction transport unit configured to suck a sheet floating from the sheet bundle upward and transport the sheet; a shutter member configured to block the flow passage in the duct; and an openable/closeable member configured to open an opening part of the duct, such that air staying in the duct by blocking the flow passage by the shutter member is discharged from the opening part.

Sheet feeding device and sheet feeding method

A microchip having a substrate, a cover member joined to one surface of the substrate, and a flow path formed on at least one of joined surfaces of the substrate and the cover member, wherein the microchip includes: a well which is an first opening for communicating into the flow path with a surface opposite to the joined surface of the substrate and is arranged on the substrate; and a chimney which is a member arranged so as to project from the surface opposite to the joined surface of the substrate and has an second opening which communicating into the well, wherein a liquid rise prevention section is formed in the chimney to prevent the liquid from rising to a top portion of the chimney.
