  • Feeding apparatus with switching pickup roller and brake roller
    Patent number: 7887043
    Abstract: In a feeding apparatus, a control device determines whether a brake roller is rotating based on the result of detection by a rotating-state detection sensor while a medium is being transferred by a separator roller. When determining that the brake roller is not rotating, the control device sets a pickup roller to non-contact state where the pickup roller is not in contact with a medium on a feed tray while a medium is not being transferred by the separator roller.
