Description:
BACKGROUND OF THE INVENTION  
         [0001]    The present invention relates to a client card mail system making use of a method for storage and retrieval of fractionalized data, by which clients&#39; taste and living custom are grasped so as to enable propaganda activity.  
           [0002]    In the conventional client card mail system, cards are issued on the basis of individual information such as addresses, telephone numbers and so on of clients, and when clients purchase the goods or receive services so that delivery and reception of money between sellers and clients occur, points according to an amount of money are added to present services, present the novel goods or mail an addressed advertisement(DM).  
           [0003]    However, for example, in the case where a selling agent which sells various goods sells the goods called D of the goods C handled by a department B of a company A, there is a client who takes either the goods C of a company E or the goods C of a company F depending on the client. Further, for example, depending on separate clients, there is a client who purchases only the goods called D of the goods C handled by a department B of a company A, and there is a client who does not purchase the sales goods of the department B.  
           [0004]    As described above, there is a problem in that even if the selling agent advertises enclosing circulars of a special sale for the goods in which clients are not interested to clients having different demands, tastes, desires and the like, such an advertisement mailed is quite useless because the client who received the notice will not buy unnecessary goods.  
         SUMMARY OF THE INVENTION  
         [0005]    It is therefore an object of the present invention to provide a client card mail system having a method for storage and retrieval of fractionalized data incorporated therein, by which clients&#39; taste and living custom are grasped from the sales goods purchased by the clients previously so as to enable useful propaganda activity of the goods.  
           [0006]    According to the present invention, there is provided a client card mail system, comprising: means for storing client information in which individual information of clients&#39; code number, name, sex distinction, age, address and telephone number; means for storing information of the goods for sales company for the sales goods, departments, classes of the goods name, goods codes, prime unit prices, and sales unit prices; means for storing information of the goods purchased by the clients; and means for retrieving clients&#39; information of the clients who actually purchased the goods setting the conditions of periods and goods classes from the information of the goods purchased; and means for outputting and printing the results retrieved, so as to enable useful propaganda activity of the sales goods.

         [0026]    The client card mail system according to the present invention is carried out making use of a computer comprising an input apparatus for client information provided with a main computer  1  and terminal devices  1   a ,  1   b ,  1   c  and  1   d  and a data storing apparatus  1   e , and a card issuing machine  2  are combined, and a client card issuing system, as shown in FIG. 1. As the client management apparatus and the client card issuing system, a conventional device, for example, a POS device may be used.  
         [0027]    As shown in FIG. 1, the terminal devices  1   a ,  1   b , 1   c  and  1   d  are a terminal machine having a scanner or the like and connected to a store processor or the like to perform a unit article information management, which is called a so-called POS terminal or merely POS (Point On Sales) (sales point information management).  
         [0028]    In the client management and the client card issuing system, information is registered in the terminal devices  1   a ,  1   b ,  1   c  and  1   d  at the store front on the basis of a registration sheet entered (filled up) by the client who desires an information registration for having a service of the store, or a sheet is sent to a card issuing central issuing agent or the like where information is registered in the main computer  1  by an operator or the like, or each client registers the client&#39;s own information in the terminal devices  1   a ,  1   b ,  1   c  and  1   d  att the store front or other terminals.  
         [0029]    Concurrently with the registration, a number for client management is given to each client, and as shown in FIG. 3, data are stored in a registered member file along with client&#39;s individual information. Then, a number of each client, the registered individual information and the like are stored in a read and write memory medium, and the card is sent to each client for issuance.  
         [0030]    Each client carries the card, and as shown in FIG. 2, when paying money for the goods purchased or the service presented, a salesman (saleswoman) or a client himself uses the card to read the card data in the terminal devices  1   a ,  1   b ,  1   c  and  1   d  (n 1 ) and connect to a network (n 2 ). Collation is made with individual information stored in the main computer  1  on the basis of individual information recorded in the card (n 3 ), and reference of client is made to the terminal devices  1   a ,  1   b ,  1   c  and  1   d.    
         [0031]    In the terminal devices  1   a ,  1   b ,  1   c  and  1   d , the price for the purchased goods is entered in a register, or a bar code is read by a laser scanner or the like so that data of the purchased goods or data of the presented service are repeatedly read every goods in the main computer  1  (n 4 , n 5 , n 6 ). The salesman receives the money (n 7 ) and issues a receipt (n 8 ). Concurrently with the issuance of the receipt, purchase information of a client is stored in a data storing device  1   e  (n 9 ).  
         [0032]    When the purchase information of a client is confirmed on the screen of the client card mail apparatus, as shown in FIGS. 3 and 4, clients are lined up in order of numbers given as shown in FIG.,  3  on the computer screen, and for example, when one out of the client information is selected, the goods purchased data of the client selected is displayed as shown in FIG. 4, which is readily distinguished.  
         [0033]    According to the present invention, as shown in FIG. 3, circulars or addressed advertisements are mailed, to many clients with clients&#39; goods purchase data gathered in the main computer  1  applied with special conditions, or being telephoned for propaganda advertisement to promote the purchase of the goods.  
         [0034]    The data take-in and the data retrieval will be described in detail hereinafter.  
         [0035]    [0035]FIG. 5 is a flow chart showing data take-in and data retrieval in the client card mail system according to the present invention. In the client card mail system according to the present invention, the retrieval by classes can be made. For example, referring to FIG. 4, in the case where circulars for special sales of the goods, beer xxx-ooo of liquor sold by company S, are sent to specific clients, the circulars may be sent to only the clients who have purchased the goods previously on the basis of sales information.  
         [0036]    Further, in the case where circulars for specific sales of the entire beer are desired to be sent, the circulars for specific sales of beer are not sent to clients who take no beer or clients who take no liquor but the circular for specific sales may be sent to only the clients who have purchased beer actually previously.  
         [0037]    So, in the client card mail system according to the present invention, the retrieval can be made with respect to the goods for which propaganda advertisement is carried out in company for the goods, departments, the goods, and classes of the goods names.  
         [0038]    Initially, as shown in FIG. 5, in the main computer  1 , purchase time for the goods advertised is set (k 1 ). Preferably the aforesaid time is suitably set according to the goods advertised and the sales time, for example, such as from January to February, a spring season (from Marcy to May), since opening a store, or for one year last year. By setting the time as described, it is possible to omit clients who have not visited the store and have not purchased anything recently.  
         [0039]    Next, whether or not retrieval is made by the company, or by the department, or by the goods is selected in class (k 2 ). In the present selection, clients who desire the specific goods or clients who desire the goods of specific companies are selected, an clients who have purchased the goods advertised are extracted.  
         [0040]    Next, the retrieval is carried out in the selected class (k 3 , k 4 , k 5 ), which is displayed on the screen, for example. FIG. 6 illustrates the state in which when the goods are selected in class and the retrieval is made, the result of retrieval is read (k 6 ), which is displayed on the screen of the main computer  1 .  
         [0041]    [0041]FIG. 6 is a view illustrating the result of retrieval of the goods to which the retrieving conditions are set in the client card mail system according to the present invention. This displays the result of retrieval relative to “Sales goods referred to the goods name xxx-ooo” with “time setting is a summer season (from June to August)”, and “class selection is the goods”. It is effective that when clients are selected on the screen, sales information of the clients can be readily observed., As shown in FIG. 5, the retrieval result which was read and displayed on the screen is output (k 7 ). The address and the postal code are printed on an envelope using a printer  3  shown in FIG. 1 on the basis of the retrieval result output (k 8 ).  
         [0042]    An apparatus may be employed in which an envelope is printed by the printer  3  and at the same time the circulars are sealed into an envelope. Alternatively, an envelope is not printed but an address and a dwelling place are printed on an addressed seal, circulars are sealed into an envelope, a seal is pasted, and an addressed advertisement is prepared.  
         [0043]    Further, circulars with a plurality of the goods combined, for example, circulars on which articles for special sale of different kinds such as beer, sliced raw fish, a kind of Chinese cabbage, and gum are prepared. Simultaneously, when clients&#39; names and addresses applied to the goods advertized are printed on envelopes and the circulars are sealed thereinto on the basis of the retrieval result of clients for advertisement of the plurality of the goods, more effective propaganda activity can be performed.  
         [0044]    FIGS.  7  to  15  show the screen displays when a program for the client card mail system according to the present invention is prepared and carried out on the main computer  1  actually. The present embodiment is not carried out by taking-in sales data from the terminal devices  1   a ,  1   b ,  1   c  and  1   d  shown in FIG. 1, so-called POS terminals on the on-line but carried out by the main computer  1  in which the sales data gathered in the main computer  1  are once shifted to a magnetic memory medium, a so-called floppy disk (hereinafter called FD) or the like to actuate the present system. Of course, the program executed in the present client card mail system may be incorporated in the main computer  1  shown in FIG. 1.  
         [0045]    [0045]FIG. 7 is a display on the screen of the main computer  1  when the client card mail system according to the present invention is carried out, showing a client card mail system menu screen. The client card mail system according to the present invention is provided with three modes of embodiments, i.e., “Sales data are taken in from a recording medium”, “Client information is retrieved and drawn out, clients&#39; retrieval information are shown in a table, and an addressed advertisement is prepared”, and “Master data is input”.  
         [0046]    As shown in FIG. 7, “Client card mail system menu”, which is a client card mail system menu screen  4 , is provided with a sales data take-in button  4   a , a client information output button  4   b , a master maintenance button  4   c , and a termination button  4   d.    
         [0047]    Here, when the sales data take-in  4   a  is selected, sales information or the like can be taken into the present client card mail system from FD or the like to apply a date. Alternatively, not reading from FD, but a program stored in the main computer  1  is incorporated into a main computer  1 ′ which controls the terminal devices  1   a  to  1   d , and terminal information (POS terminal information) is instantaneously taken in on the on-line. The sales data take-in  4   a  will be described with reference to FIG. 8.  
         [0048]    When the client information output  4   b  is selected, client information can be extracted and drawn out on the basis of the retrieval conditions set from data stored in the main computer  1 , and the name and address for addressed advertisement can be printed on an addressed seal on the basis of the selected client information. The client information output  4   b  will be described with reference to FIGS.  9  to  14 .  
         [0049]    When the master maintenance  4   c  is selected, it is possible to perform inputting, changing and deleting of data which rarely change through a certain period, a so-called master record. In the present client card mail system, regional information, goods information and client information correspond to the master record. Data of the present master record are stored in a file in which all the information necessary for data processing are collected, a so-called basic file (called a master file also). The master maintenance  4   c  will be described with reference to FIGS.  15  to  18 .  
         [0050]    When the termination  4   d  is selected, the client card mail system menu screen  4  is closed to terminate the program for the client card mail system.  
         [0051]    In the following, three modes of embodiments, i.e., the sales data take-in  4   a , the client information output  4   b , and the master maintenance  4   c  will be described in order with reference to the display screen.  
         [0052]    [0052]FIG. 8 is a display on the screen of the main computer  1  when the client card mail system according to the present invention is carried out, showing a sales data take-in screen. In the present embodiment, there is employed a program in which sales data are collected every day and taken into the main computer  1 . Therefore, when sales data are taken into the main computer  1  by FD, data are stored after the take-in date has been applied to data.  
         [0053]    This is because records such as when sales data were taken in, and when was the latest input (that is, the latest update date of sales data) are left.  
         [0054]    When sales data are taken into the main computer  1  from FD, they may be taken in without applying dates relative to all the data. When the sales data take-in button  4   a , in which dates and time on which clients purchase the goods are shown in FIG. 7, is depressed, the sales data collection screen  5  appears.  
         [0055]    The sales data collection screen  5  is provided, as shown in FIG. 8, with a date write-in column  5   a , a OK button  5   b , and a termination button  5   c . A FD is inserted into a read/write device, a so-called floppy disk drive provided in the main computer  1 , a date of sales data stored in the FD is written into the date write-in column  5   a , and when the OK button  5   b  is depressed, data is taken into the main computer  1 . The termination button  5   c  is depressed to close the sales data collection screen  5 , then returning to the client card mail system menu which is the client card mail system menu screen  4 .

         [0062]    [0062]FIG. 10 is a display on the screen of the main computer  1  when the client card mail system according to the present invention is carried out, showing a client retrieval screen. When the client information retrieval button  6   a  shown in FIG. 9 is depressed, the client retrieval screen  7  shown in FIG. 10 appears.  
         [0063]    The present client retrieval screen  7  is provided with a date range designation column  7   a,  a region range designation column  7   b,  a goods designation  7   c,  a sales rate setting column  7   h,  an output designation column  7   i,  an output button  7   j,  and a termination button  7   k.  In the present client retrieval screen  7 , the conditions of a time range, a regional range, and the goods are imposed to retrieve and select clients to which circulars of the goods are distributed.  
         [0064]    In the date range designation column  7   a,  the time for retrieving the client who purchased the goods designated in a certain time is set. The region range designation column  7   b  is the column which for example, in a branch store for special sale, sets the retrieval conditions for specifying the goods purchaser class who lives in a certain regional range about the branch store.  
         [0065]    The goods designation  7   c  sets the goods put on circulars out of a plurality of the goods. That is, this is the column (item) for setting the designated goods in order to retrieve the goods purchaser who purchases the goods in a certain time and lives in the designated region for distributing circulars for advertisement of the designated goods.  
         [0066]    The goods designation  7   c  is provided with a goods code selection column  7   d,  an addition  7   e,  a cancellation  7   f,  and a goods code setting column  7   g.
