If the user enters the rent out washing machine intending to use, and the washing conditions through the communication terminal 40 (S41), the communication terminal 40 checks the present state of the rent out washing machine selected by the user (S42).

If the rent out washing machine selected by the user is under operation, i.e., under use presently, the product information on the rent out washing machine selected by the user is compared to product information on all registered rent out washing machines (kinds of washing machines, washing capacities, kinds of motors, and so on), in a search for a rent out washing machine having the same product information on the rent out washing machine selected by the user (S43, and S44).

For an example, of the product information on the rent out washing machines, kinds and capacities are compared, for selecting a rent out washing machine having the same kind and capacity with the washing machine selected by the user.

As a result of the search, if there is no rent out washing machine having the same product information, an error message (for an example, “the washing machine ‘A’ selected by the user is under use. Select a washing machine again.”) is forwarded (S45, and S46).

Opposite to this, if a rent out washing machine having the same product information exists, a message (for an example, the washing machine ‘A’ is under use. You may use another washing machine ‘C’. Will you ?) asking if the user uses other washing machine is displayed (S47).

Noticing that a washing machine having product information the same with the product information of the washing machine selected by the user is selected, if the user determines to use the washing machine (S48), the washing signal and the washing conditions entered by the user are provided to the rent out washing machine (S49).

The rent out washing machine, having the washing signal received from the communication terminal 40, becomes ready to perform washing according to the washing conditions.

As has been described, the device and method for integrated management of rent out washing machines have the following advantages.
