A sheet feeding device includes a storage, a discharger, an angle adjuster, and an urging body. The storage stores a sheet bundle. The discharger contacts and discharge an uppermost sheet of the sheet bundle from the storage in a sheet conveying direction in which the uppermost sheet is conveyed. The angle adjuster changes an angle according to a remaining amount of the sheet bundle in the storage. The urging body urges a trailing end of the uppermost sheet in the sheet conveying direction toward the discharger in stages according to the remaining amount.

Sheet feeding device and image forming apparatus

A sheet conveying device includes a pair of rollers, a biasing member, a guide member, a biasing support, and a biasing force changer. The pair of rollers includes a first roller and a second roller disposed in contact with the first roller. The pair of rollers is configured to hold a sheet between the first roller and the second roller. The biasing member is configured to bias the first roller toward the second roller. The biasing support is configured to support the biasing member and has a guide target member configured to slide along the guide member to move the biasing support. The biasing force changer is configured to change a biasing force of the biasing member along with movement of the biasing support. The guide target member has a portion projecting into a sheet conveyance passage through which the sheet is conveyed by the pair of rollers.

A sheet conveying device includes a pair of rollers including a first roller and a second roller to hold a sheet conveyed between the first and second rollers; a biasing member to bias the first roller toward the second roller; a biasing force changer to change a biasing force of the biasing member; control circuitry to, when a predetermined changing condition is met, cause the changer to change the biasing force and cause the rollers to convey the sheet; an operation detector to detect a changing operation of the changer; and a notification device to notify an abnormality of the changing operation when the operation detector detects the abnormality. When the operation detector detects the abnormality, the control circuitry performs sheet conveyance control to cause the rollers to convey the sheet without causing the changer to change the biasing force, regardless of whether the predetermined changing condition is met.

A chemiluminescence analyzer includes a reactor to cause waste liquid discharged from a blood purification apparatus to react with a reagent solution, a photodetector to measure an intensity of chemiluminescence arising in the reactor, a first liquid conveyor to convey the waste liquid from a waste liquid passage of the blood purification apparatus to the reactor, and a second liquid conveyor to convey the reagent solution to the reactor. The chemiluminescence analyzer further includes a liquid mixture passage extending from the reactor to convey a liquid mixture including the waste liquid and the reagent solution after reaction, a joint to couple the liquid mixture passage to the waste liquid passage of the blood purification apparatus, and an electric interface for connection with an external device.

A measuring apparatus includes a light receiving device, a housing, an optical window, an electrical connection line, and a line enclosure. The light receiving device receives light and output a signal. The housing, made of a conductive material, covers the light receiving device. The optical window transmits the light. The optical window includes a conductive part having conductivity. The electrical connection line transmits the signal. The line enclosure is disposed around the electrical connection line and electrically connected to the conductive part and the housing.
