Zusammenfassung: | A number of controllers (38) are provided for respective operation devices (121a,121b to 129a,129b) connected either in series or in parallel. Each controller has signal transmitting units (33,34) and signal receiving units (35,36) for the communication with the adjacent devices. A connection unit (37) judges whether or not the device is positioned at a fixed starting position which is the starting point of the general control in the group of devices. If the device is positioned at this fixed starting point, the connection unit specifies the device to be a master operation device and, if it is not, specifies the operation device as a slave device which operates independently. Thus, the respective operation device can judge itself to be a master operation device or a slave operation device. |
