To efficiently perform the secure maintenance operation of the automatic vending machine as the automatic vending machine manager intends by turning on a lighting means when a door is opened for the confirmation of the vending state of the automatic vending machine, its maintenance, etc.

An arithmetic control part 3 reads and writes data based upon output data by reading a signal indicating which switch of the choice input device 1 is pressed and outputs a signal for turning on the lighting means 2. When the automatic vending machine is in normal operation at the time of operation for the confirmation of the vending state of the automatic vending machine, its maintenance, etc., the arithmetic control part 3 always outputs the signal for turning on the lighting means 2 provided on the external front of the choice input device 1, thereby turning on the lighting means 2. Thus, the lighting means 2 illuminates and then the choice input device 1 can be operated while the contents, etc., of an explanation label for automatic machine specifications, etc., stuck in the automatic vending machine are confirmed in the night and day and even when the circumference is dark.
