Abstract
The present invention aims to provide a zone controller that enables construction of a conveyor line adapted for articles having various shapes and weights. The zone controller includes: an output terminalfor output of a driving status signal representing a driving status of the driving roller; an input terminalfor input of a driving status signal; and a controlling sectionfor generating a controlling signal for controlling the driving roller. The controlling section is capable of being switched between a master control mode and a slave control mode. In the master control mode, the controlling section generates the controlling signal by determining the need for driving the driving roller and outputs a driving status signal equivalent to the controlling signal via the output terminal, and in the slave control mode, by employing a driving status signal transmitted via the input terminalas the controlling signal, the controlling section controls the driving roller synchronously with the control by the zone controllerfrom which the driving status signal is transmitted.
