A feeder maintenance device (11) manages history information (84) including at least one of the number of times of use of an expendable item and a measurement value of the expendable item concerning a cleaner unit (an air washing unit (30, 40, 49) and a liquid washing unit (34, 44)), and causes information about a use status of the expendable item to be displayed and output as an expendable item screen on the basis of the history information (84). The feeder maintenance device (11) can notify a worker of information about the expendable item. In addition, the feeder maintenance device (11) enables the worker to exchange or supplement the expendable item. Accordingly, a maintenance process for a feeder (60) can be performed with increased reliability. |
