## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to charging methods and imaging apparatuses, and more particularly to a method of charging with a “use point” that is a common unit of charging for use of apparatuses and/or services and an imaging apparatus supporting such a method.
2. Description of the Related Art
Conventionally, copier charges are made according to the number of copies made by the copier. In the case of making N copies for A yen per copy, for instance, A times N yen are charged in total. A bill collector is informed of the number of copies made by a user and charges the user accordingly.
However, in the case of charging according to the number of copies, a color copy and a monochrome copy have different unit prices.
Therefore, the bill collector, receiving information or notification of the number of copies, calculates charges for color copies and monochrome copies separately based on their respective numbers. Then, the bill collector adds up the respective charges so as to charge the user.
In this case, however, the user may be charged a wrong amount due to the occurrence of an error in reading the values of their respective counters or in informing the bill collector of the read value of each counter. First of all, reading and reporting the counter value cost time and trouble.
Recent multi-function printers (MFPs) include a built-in hard disk (HD). The MFP enables a user to store an image read by the scanner function in the HD and to distribute the stored image to other apparatuses through a network. Further, the image stored in the HD can be stored via the network in an image data storage server. Moreover, the MFP itself can be used as an image data storage server connected to the network.
Such a high-performance MFP requires services that cannot be charged for by the conventional method of charging according to the number of copies or printouts. Such services include upgrading of MFP software and provision of instructions on how to operate the MFP.
Further, in a high-performance MFP, even a price system for a service measurable by the number of copies or printouts is complicated and thus difficult for clients to understand. It is expected that this may cause an increase in management cost.
SUMMARY OF THE INVENTION
Accordingly, it is a general object of the present invention to provide a charging method and an imaging apparatus in which the above-described disadvantage is eliminated.
A more specific object of the present invention is to provide an appropriate, equitable, and simple method of charging for use of apparatuses and/or services and an imaging apparatus supporting such a method.
The above objects of the present invention are achieved by a charging method using a use point that is a unit, common to a plurality of apparatuses, of charging according to use thereof, the charging method including the steps of (a) converting a result of use of each of functions of each of the apparatuses to use points, (b) totaling the use points of each of the apparatuses obtained in the step (a) based on a predetermined unit, and (c) charging for use of each of the apparatuses based on the use points totaled in the step (b).
According to the above-described charging method, charging for the use of an apparatus is performed based on the totaled use points to which the use of the functions of the apparatus is converted. Therefore, even when an apparatus has multiple functions, charging can be performed appropriately, equitably, and simply for the use of the apparatus.
The above objects of the present invention are also achieved by a charging method using a use point that is a unit, common to a plurality of services, of charging according to use thereof, the charging method including the steps of (a) converting a result of use of each of the services to use points, (b) totaling the use points of the services obtained in the step (a) based on a predetermined unit, and (c) charging for the use of the services based on the use points totaled in said step (b).
According to the above-described charging method, services such as MFP software upgrading and provision of MFP operating instructions, which cannot be charged for by the conventional method, can be charged for appropriately, equitably, and simply.
The above objects of the present invention are also achieved by a charging method using a use point that is a unit, common to use of an apparatus and a service, of charging according to the use thereof, the charging method including the steps of (a) converting a result of use of each of the apparatus and the service to use points, (b) totaling the use points of the apparatus and the service obtained in the step (a) based on a predetermined unit, and (c) charging for the use of the apparatus and the service based on the use points totaled in the step (b).
According to the above-described charging method, a charge for the use of an apparatus and a charge for the use of a service are totaled when the charges are made. Therefore, a payment can also be made for the totaled charges. This saves time and trouble in making a charge and a payment for the use of an apparatus and a service.
The above objects of the present invention are further achieved by an imaging apparatus outputting a use point that is a unit, common to a plurality of apparatuses, of charging according to use thereof, the imaging apparatus including: a conversion part converting a result of use of each of functions of the imaging apparatus to use points; a totaling part totaling, based on a predetermined unit, the use points of the functions obtained in the conversion part; and an output part outputting the use points totaled in the totaling part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A description will now be given, with reference to the accompanying drawings, of an embodiment of the present invention.
First, a description will be given, with reference to FIG. 1, of a basic concept of the present invention. A charging method for the MFP, for instance, will be described.
[Basic Operation Flow]
In step S1 of FIG. 1, a “use point” is set with respect to each function of the MFP. The use point is a unit of charging for use of each function of the MFP. For instance, the use point, as a charging unit, is set with respect to each of one printout, one A3 copy, one A4 copy, and one A4 duplex copy. The use point system may be set so that a point is added for every predetermined black area (6%, for instance) of the entire copy area. Another use point system is set for color copying. The set contents of the use point system are stored in a memory as a conversion table.
In step S2, every time the MFP is used, referring to the conversion table, the state of use (time length, the number of times, etc.) of each function is converted to the corresponding use points to be stored in the memory. Next, in step S3, the use points of the functions are totaled based on a predetermined unit at predetermined intervals. Then, in step S4, a charge is made based on the totaled use points of the functions.
The use point may be used in common with other apparatuses or services. In this case, the use points may be totaled according to a unit of collecting bills (a bill collection unit) or a unit suitable for collecting bills.
[Operation Flow of the Present Invention]
A description will be given, with reference to FIG. 2, of an operation flow of the present invention.
In step S10 of FIG. 2, an apparatus and/or a service is used. In step S11, data on the use of the apparatus and/or the service (hereinafter referred to as use data) is obtained. The use data may be automatically generated by the apparatus used or input through a terminal (which may be the apparatus used if the apparatus used can function as a terminal). Thereafter, the operation flow is divided into four parts according to the following cases.
(a) [In The Case Where The Apparatus Used Totals And Displays The Use Points]
In step S12, the apparatus used, which includes a memory storing the conversion table, refers to the conversion table and converts the obtained use data to use points. In step S13, the apparatus used totals the use points based on a predetermined unit at predetermined intervals. Next, in step S14, the apparatus used stores the totaled use points, and in step 15, displays the totaled use points as required on the display unit of the apparatus or an external display.
A charge is made based on the displayed value. Thereby, the use point value or the sum of the use points of the functions of each apparatus can be known.
(b) [In The Case Where The Apparatus Used Totals The Use Points And An External Apparatus Uses The Totaled Use Points]
In step S12, the apparatus used, which includes a memory storing the conversion table, refers to the conversion table and converts the obtained use data to use points. In step S13, the apparatus used totals the use points based on a predetermined unit at predetermined intervals. Next, in step S14, the apparatus used stores the totaled use points in a predetermined memory. Then, in step S16, accessed by the external apparatus, the apparatus used outputs the use points stored in the memory. In step S17, the external apparatus performs billing based on the use points.
The external apparatus of the operation flow (b) is preferably a charging and/or billing system. In this case, charging and/or billing can be performed efficiently with a reduced amount of charging and/or billing data.
(c) [In The Case Where An External Apparatus Totals The Use Data And Converts The Use Data To Use Points So As To Perform Charging And/or Billing Based On The Use Points]
The external apparatus accesses each apparatus via a network and collects the use data.
In step S18, the external apparatus, which includes a memory storing the conversion table, refers to the conversion table and converts the use data collected from the apparatus used to use points. In step S19, the external apparatus totals the use points based on a predetermined unit such as a bill collection unit at predetermined intervals. Next, in step S20, the external apparatus stores the totaled use points in a predetermined memory. Then, in step S21, the external apparatus outputs the stored use points at a predetermined date and time, and in step S22, the external apparatus performs billing based on the use points.
The external apparatus of the operation flow (c) is a system for collecting information on the state of each apparatus used as well as for charging and billing. In this case, the system for collecting information on the state of each apparatus used includes the charging and billing functions so as to be capable of performing information collecting, charging, and billing with more efficiency.
(d) [In The Case Where An External Apparatus Collects The Use Data And Converts The Use Data To Use Points So That a Billing Apparatus Performs Billing Based On The Use Points]
The external apparatus such as a use data collection center accesses each apparatus via a network and collects the use data.
In step S18, the external apparatus, which includes a memory storing the conversion table, refers to the conversion table and converts the use data collected from the apparatus used to use points. In step S19, the external apparatus totals the use points based on a predetermined unit such as a bill collection unit at predetermined intervals. Next, in step S20, the external apparatus stores the totaled use points in a predetermined memory. Then, in step S21, accessed by the billing apparatus, the external apparatus outputs the stored use points, and in step S23, the billing apparatus performs billing based on the use points.
The external apparatus of the operation flow (d) collects information on the state of each apparatus used and converts the information to use data. Then, the external apparatus makes a charge based on the result of the conversion. Therefore, the functions are distributed so as to realize a very expansive system. Instead of the external apparatus, the billing apparatus may total the use points based on a predetermined unit at predetermined intervals in step S19.

The management terminal 20 is a terminal for controlling the use data collection center 11. The communication server 21, which communicates with the apparatuses 11 through 1N directly or via the network 10, receives the use data of the apparatuses 11 through 1N therefrom. Further, at the request of any of the apparatuses 11 through 1N, the communication server 21 transmits thereto its present use point value or its use point value for a predetermined period of time.
The system management server 22 manages the entire use data collection center 11 of FIG. 6. The database server 23 manages the database 24. The database server 23, for instance, stores, as required: a (conversion) table correlating each apparatus use and/or each service use with its corresponding use point as a charging unit; the use points (use point values) recorded client by client, apparatus by apparatus, and function by function in a bill collection unit; client information; apparatus information; and use state information. The database 24 stores data used in the conversion server 26, the totaling server 27, and the billing server 28. The firewall 38 ensures security in the connection with the network 10.
The conversion server 26, referring to the conversion table stored in the database server 23, converts the use data of each of the apparatuses 11 through 1N obtained thereby to use points. The totaling server 27 totals the use points of each of the apparatuses 11 through 1N based on a predetermined unit at predetermined intervals. The billing server 28, based on the use points totaled by the totaling server 27, bills the user of each of the apparatuses 11 through 1N for the use thereof.
According to the above-described system, when the apparatus 1 is used, the use data of the apparatus 1 is transmitted therefrom to the use data collection center 11 at any time, periodically, or at the request of the use data collection center 11. Thereafter, the conversion server 26, referring to the conversion table stored in the database server 23, converts the received use data to use points, and stores the use points in the database server 23. Next, the totaling sever 27 totals the use points stored in the database server 23 at predetermined intervals, and stores the totaled use points in the database server 23. Then, at any time or a predetermined date and time, the billing server 28 bills the user of the apparatus 1 for the use thereof based on the use points stored in the database server 23.
According to the system of FIG. 3, the use data collection center 11 collects the use data of each of the apparatuses 11 through 1N and converts the collected data to the respective use points. Therefore, the collection and the conversion of the use data can be performed with efficiency.
[In The Case Where The Apparatus 1 Displays The Use Point Value]
A description will be given, with reference to FIG. 7, of the case where the use point value is displayed on an apparatus such as an MFP.
FIG. 7 is a diagram showing another configuration of the apparatus 1 according to this embodiment. In FIG. 7, the same elements as those of FIG. 4 are referred to by the same numerals.
The apparatus 1, which is an apparatus for office or home use, such as an MFP, a printer, a copier, or a facsimile machine, includes the communication I/F 70, the control part 71, the information processing part 72, the apparatus information collection part 73, the operation screen 74, a use state information database 75, and a conversion table 76 in its main body.
The control part 71 controls the entire apparatus 1. In addition, the control part 71 controls the communication I/F 70, the information processing part 72, the apparatus information collection part 73, and the operation screen 74.
The information processing part 72, which is connected to the use state information database 75 and the conversion table 76, collects information including the use data of the apparatus 1, and stores the information in the use state information database 75. Further, the information processing part 72 converts the use data of the apparatus 1 to use points referring to the conversion table 76, and stores the use points in the use state information database 75. The apparatus information collection part 73 totals the use points based on a predetermined unit at predetermined intervals, and stores the totaled use points in the use state information database 75 according to the operation of the information processing part 72. The operation screen 74 is formed of a touch panel. By following instructions displayed on the operation screen 74, the apparatus and/or service use data can be input, and the present use data or the use data for a predetermined period of time can be displayed.
The use data or the totaled use points of the apparatus 1 may be transmitted to an external apparatus via the communication I/F 70 as required. That is, the totaled use points are collected via the network 10 by an external apparatus such as the use data collection center 11, and charging is performed based on the collected use points. This reduces the amount of charging-related data flow on the network 10.
If the apparatus 1 has a normal mode and a power-saving mode, the use points may be calculated in each of the modes and displayed as required.
The client can determine, referring to the calculated use points of each of the modes, which of the two is the more suitable, to frequently switch off the power or to use the power-saving mode. This helps the client save power and reduce costs.
In the present invention, the following items are suitably converted to the use points, for instance.
Use of Apparatus
In converting the use of the apparatus 1 to use points, different conversions may be performed in the normal mode and the power-saving mode since the degree of consumption of expendable supplies differs between the normal mode and the power-saving mode.
Further, different conversions may be performed in color printing or copying and monochrome printing or copying.

    
    
        Replenishment of expendable supplies
        Technical fees for periodic checks or failure recovery operations
        Provision of operating instructions
        Function upgrading
        Consultation service by phone, etc.
        Additional memory installation
        Additional function installation
    
    


According to the embodiment of the present invention, appropriate, equitable, and simple charging, easy for the users to understand, can be performed without complicating the price system for the use of a high-performance apparatus such as an MFP.
The present invention is not limited to the specifically disclosed embodiment, but variations and modifications may be made without departing from the scope of the present invention.
The present application is based on Japanese priority application No. 2002-084551 filed on Mar. 25, 2002, the entire contents of which are hereby incorporated by reference.
