摘要： A cooling device includes a cooling member to absorb heat from a conveyed sheet and a plurality of cooling units to cool the cooling member. Each of the cooling units includes a coolant channel through which a coolant flows and a liquid-cooling device configured to cool the coolant that flows in the coolant channel. The coolant channels are disposed on or inside the cooling member and arranged side by side in a sheet conveyance direction. The coolant channels includes a downstream coolant channel being downstream from at least one of the plurality of coolant channels in the sheet conveyance direction, and an upstream coolant channel being upstream from the downstream coolant channel in the sheet conveyance direction. One of the liquid-cooling devices coupled to the downstream coolant channel has a cooling capacity higher than a cooling capacity of another of the liquid-cooling devices coupled to the upstream coolant channel.

摘要： A device attaches and detaches at least one of rollers in a belt conveyor in which an endless belt is wound around the rollers between a front plate and a rear plate of the belt conveyor. The device includes a guide and a roller holder. The guide has a base end and extends along a longitudinal direction of the detachable roller and includes a guide groove. The roller holder holds the detachable roller and includes an engagement portion, another engagement portion, and a guided portion. The engagement portion detachably engages with the front plate. The other engagement portion detachably engages with the rear plate. The guided portion slides along the guide groove toward the rear side or the front side of the device to engage or disengage the engagement portion with or from the front plate and engage or disengage the other engagement portion with or from the rear plate.

摘要： A conveyance device includes a conveyance member, a guide, and a rotator. The conveyance member has a conveyance surface with a joint, the conveyance member to convey an object to be conveyed, with the object on the conveyance surface. The guide approaches the conveyance surface and guides the object from or to the conveyance member. The rotator contacts the conveyance surface. The guide displaces in a direction perpendicular to the conveyance surface, in conjunction with displacement of the rotator when the rotator contacts the joint.
