PURPOSE:To allow the processing unit to manage concentratingly charging data of a charging equipment by connecting the charging equipment, plural equipments having the address of the charging equipment by means of an optical communication equipment. CONSTITUTION:Each of game machines G-1 to G-N is respectively provided with each of slave sets S-1 to S-N (charging equipments). Then a detection contact C-1 through which an operating state of the game machine G-1 is detected as a contact signal is connected to the slave set S-1, and the contact signal through the detection contact C-1 is sent to a master set via an optical communication equipment T-1 together with the address of the game machine G-1. The optical receiver of the master set monitors cyclicly the presence of data sent from optical communication equipments T-1 to T-N and receives the data. Then a personal computer (processing unit) 14 processes data collected by the master set. Furthermore, the optical receiver of the master set is located on the ceiling of a game center and is able to receive always the signals from the slave sets S-1 to S-N. |
