Abstract: An abnormality inspection system S1 according to an embodiment includes: an image acquisition unit configured to acquire a plurality of pieces of continuous pickup data of a component such that an identical spot of the component is contained in mutually different regions of the plurality of pieces of continuous pickup data; and a determination unit configured to detect presence or absence of abnormality in the plurality of pieces of continuous pickup data, and to determine that the component is abnormal, in a case where the abnormality is detected in all of the plurality of pieces of pickup data.

Abstract: A sheet type determining device including a guide that guides a sheet along a sheet conveyance path to a destination. The sheet conveyance path is between a first guide surface and a second guide surface facing each other across an interval. The sheet type determining device further includes a determiner that determines a sheet type when the sheet is in the sheet conveyance path, without having contact with the sheet in conveyance, and one or more regulators that regulate a displacement range of the sheet at a determining position, the displacement range being in a direction of the interval of the first and the second guide surfaces. Each of the regulators is a member that protrudes in an arc shape from the first or the second guide surface toward the guide surface opposite, and is spaced from the guide surface or another one of the regulators opposite.

Abstract: A sheet conveyance device includes: a container that accommodates loaded sheets; a feeding mechanism that continuously feeds the sheet from the container; a conveyance path on which the sheet is conveyed; and a pitch adjustment mechanism provided on the conveyance path and which adjusts a pitch of a preceding sheet and a subsequent sheet, wherein the pitch adjustment mechanism includes a pitch adjustment roller pair including a first pitch adjustment roller and a second pitch adjustment roller that sandwich the conveyance path and are in pressure contact with each other, the first pitch adjustment roller is driven and rotated in a direction following a sheet conveying direction, the second pitch adjustment roller is driven and rotated in the direction following a sheet conveying direction, and the second pitch adjustment roller is connected to a drive shaft that drives the second pitch adjustment roller via a one-way clutch.
