ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a technology for calculating a value remaining in an electrical apparatus, of which value decreases with use, and particularly relates to a technology for calculating the residual value of the electrical apparatus based on its history of use.
2. Description of the Background Art
In recent years, attention has been given on reduction of refuse, garbage or the like for environmental conservation. The refuse or the like can be reduced by reusing or recycling products. In the “reuse” process, a product or a unit (or a part) forming the product is repaired or cleaned, and is used again as the same type of product or unit (or part). In the “recycle” process, a unit or part forming a product is restored to an original material for use as a material (material recycle). Hereinafter, the reuse and the material recycle are inclusively referred to as the “recycle”.
For promoting the recycle of products, methods of accurately calculating a value of a product to be recycled have been proposed or developed. As one of such methods, Japanese Patent Laying-Open No. 9-251486 has disclosed a method of calculating values of secondhand or used cars.
The method of calculating the value of the used car disclosed in the above publication can be used when estimating the value of the used car for trade-in or purchase, and includes the steps of determining a manufacturer of a used car to be estimated, selecting a model and a type of the car to be estimated, determining a year of first registration of the car and a type of a transmission thereof, determining a grade of the car, determining a model year of the car, determining a body color of the car, obtaining a basic estimated value from the data thus determined and selected, adding a predetermined value to the basic estimated value if a total mileage is total mileage is shorter than a standard mileage of the same model and type, and subtracting a predetermined value from the basic estimated value if the total mileage is longer than the standard mileage.
According to the disclosed method, the estimated value of the used car for trade-in or purchase can be easily and accurately calculated based on the total mileage, which represents a current state of the car to be estimated.
Although the disclosed method allows calculation of a value remaining in the car based on the total mileage of the car, i.e., a product or article of trade, an electrical apparatus cannot provide an index corresponding to the above total mileage. Therefore, the value remaining in the electrical apparatus cannot be accurately calculated according to the disclosed method. Due to difficulty in calculation of the value remaining in the electrical apparatus, recycle (resale market) of electrical apparatuses is less popular than that of automobiles. For promoting the recycle of electrical apparatuses, it has been desired to provide some method allowing easy determination of residual values of the electrical apparatuses.
