PURPOSE: To eliminate the need to gather data by a person at the automatic vending machine and to gather the data in an optional time zone by receiving management information by a telephone-set side radio transmitter receiver and sending it to a management center side through a public telephone line.
CONSTITUTION: On the side of the management center 1, the telephone-set side radio transmitter receiver 8 is actuated through the public telephone line 4 on the basis of a discrimination number given to each automatic vending machine 9 to sends an actuation signal to a single or plural automatic-vending-machine side radio transmitter receivers 10. A spread spectrum system is employed as a data modulation system between radio transmission and reception. Consequently, a signal is sent from the side of the management center 1 to the telephone-set side ratio transmitter receiver 8 through the telephone line, i.e., on a wire basis so as to obtain the information of the automatic vending machine 9. Then a radio communication is made between this telephone-set side radio transmitter receiver 8 and automatic-vending-machine side radio transmitter receivers 10... and the data of the sides of the automatic vending machines 9... are inputted to the management center 1 through the automatic-vending- machine side radio transmitter receivers 10..., the telephone-set side radio transmitter receiver 8, and the telephone line 4.
