Abstract
A plurality of nodes 2-n are assigned to a plurality of operators. The each node 2-n detects input operation of the corresponding operator to transmit detection information in a wireless manner. A host 27 receives the detection information transmitted in the wireless manner by the each node 2-n. The host 27 transmits a beacon signal BS to the plurality of the nodes 2-n in a predetermined cycle CY. The each node 2-n performs processing of detecting the input operation while changing time, i.e., at times ST0 to ST3 to transmit the detection information to the host 27 in response to the beacon signal BS. It is possible to finely detect order of changes of the detection information among the plurality of the nodes.
