摘要： A media conveying apparatus includes a media tray, a feed roller, a first media sensor, a second media sensor, and circuitry. The first media sensor is located downstream from the feed roller in a media conveyance direction. The first media sensor is located inside of a side wall of a media conveyance path and outside of a maximum size media supported by the media conveying apparatus placed on the media tray in a direction perpendicular to the media conveyance direction. The second media sensor is located downstream from the first media sensor in the media conveyance direction. The circuitry executes error handling based on a detection result of the medium by the first media sensor and a detection result of the medium by the second media sensor.

摘要： A media feeding apparatus includes: a feed roller, a separation roller, and a pressing portion to press one of the feed roller and the separation roller against the other to form a nip region. A surface of the feed roller has grooves extending in a width direction of the feed roller. The grooves are arranged with a pitch such that at least one groove is always present in the nip region during feeding of the medium. A width of each groove is 0.5 mm or greater and is set such that a contact area ratio is 0.5 or greater, the ratio being a value obtained by {(a surface area of the feed roller in the nip region−an area of the at least one groove of the feed roller in the nip region)}/(the surface area of the feed roller in the nip region). A surface of the separation roller has grooves extending in a circumferential direction of the separation roller.

摘要： A medium conveying apparatus includes a loading tray to place media, a feed roller to separate and sequentially feed the media placed on the loading tray, a motor to drive the feed roller, a sensor located on a downstream side of the feed roller in a medium conveying direction to detect a medium, and a processor to control the motor. In a separation period from a start of medium feeding by the feed roller to detection of a front edge of the first medium by the sensor, when feeding a first medium of a plurality of media placed on the loading tray, the processor controls the motor to rotate the feed roller at a constant speed, and when feeding a second or subsequent medium, the processor controls the motor to rotate the feed roller at a first speed and then at a second speed higher than the first speed.
