An object of the invention is to provide a zone controller and a conveyor device which facilitate identification of a defective part when a defect occurs in a distributed control type conveyor device. There is provided a zone controller (10) which is used for a conveyor device (1) in which a plurality of zone conveyors (2) are arranged in series, which manages one or a plurality of the zone conveyors (2) to control an operation thereof, and which is configured to receive a signal from a different zone controller (10) and transmit a signal to the outside. The zone controller (10) includes: a signal creation function that creates a predetermined abnormality alarm signal and transmits the created abnormality alarm signal to the outside when an abnormality occurs in a zone managed by the zone controller itself; a signal reception function that receives the abnormality alarm signal from the different zone controller (10); a signal processing function that applies certain processing to the received abnormality alarm signal; and a processed signal transmission function that transmits the signal processed by the signal processing function to the outside as the abnormality alarm signal.
