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 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： An open and close device, a sheet conveyor, and an image forming apparatus. The open and close device includes an open and close portion to open or shut, a biasing mechanism to bias the open and close portion in an opening direction, and a holder to hold the open and close portion shut. The biasing mechanism includes a first spring whose biasing force is invariable regardless of a stroke of the first spring, and a second spring whose biasing force is variable due to a stroke of the second spring. The sheet conveyor includes the open and close device, and the open and close portion includes a conveyor to convey a sheet. The image forming apparatus includes the sheet conveyor.

摘要： An airbag device has an airbag that is wound in a rolled state, mounted in a vehicle longitudinal direction of a vehicle and deployable in a curtain-like manner in a vehicle compartment by a gas generated by an inflator in case of emergency. A cover cloth is provided so as to be wound to cover at least part of an outer circumference of the airbag extending in a longitudinal direction. The cover cloth has a first folded-back part that is formed by folding back one end of the cover cloth in a circumferential direction of the outer circumference of a cross section, which is perpendicular to the longitudinal direction of the folded airbag. An edge of the outer circumference of the airbag is held between the first folded-back part and the other end of the cover cloth.
