To provide a car washing machine system capable of saving time for an input by bringing an IC tag reader closer and suppressing the cause of failure or damage.

Only if an IC tag is attached to a vehicle or a freely portable object and is brought closer to the IC tag reader 207 interlocking with a main panel 102 of the car washing machine, useless time is saved without requiring an input by a person. When a set condition is different from the condition of the vehicle applied to the car washing machine, the cause of the failure or damage can be suppressed by temporarily stopping this system and notifying a user (holder) or a store person of information by performing communication without wires or with wires.
