It goes without saying that usually a plurality of sales terminals 1 are arranged.

Next, a data selling method by the data selling system will be described with reference to flowcharts of FIGS.

First, the operation up to data storage by the sales terminal 1 will be described with reference to the flowchart of FIG. A list of sales data stocked by each of the sales data information sources 3A to 3C is received from each of the sales data information sources 3A to 3C via the data reception server 2 in advance, and the data list is displayed as a list of purchaseable data. It is displayed on the means 14.

In this state, it is monitored whether or not the purchase request of the purchaser has been inputted to the purchase request input means 13 via the input operation section 31 (S31). Then, when it is confirmed that the purchase request has been input, the purchase request input means 1
It is monitored whether or not an input relating to permission to insert an advertisement into the recording medium has been made for S3 (S32). If an input to permit insertion of an advertisement is made in S32, it is monitored whether or not a setting input of the amount of advertisement to be inserted has been made to the purchase request input means 13 (S33). S3
The setting of the advertisement amount in 3 is performed as follows.

In the present embodiment, the advertisement insertion processing refers to the following two processings. The first process refers to a process of writing advertisement information data (character data, video data, audio data, and the like) along with sales data to a recording medium. The second process is a process of printing advertisement information on a label surface of a recording medium (CD-R).

First, the setting of the advertisement amount in the first processing of the advertisement insertion processing will be described. The CD-R used as a recording medium in the present embodiment has a relatively large capacity (about 650 MB). It is possible to erase an area in which data has been written once and then write another data in that area again. Cannot be used (write area cannot be reused). ・ Even after the write operation has been completed, data can be written again to the data unwritten area (however, dedicated writing application software is required) [Unwritten area can be reused]).

Therefore, first, the remaining non-recording area of the recording medium is calculated from the data amount of the purchase desired data of the purchaser (this is performed, for example, by the control means 16), and the non-recording area is converted into the advertisement insertable area. Is displayed on the display means 14. Further, at this time, the amount of reduction of the selling price accompanying the insertion of the advertisement is converted into a unit area and displayed on the display unit 14. Specifically, for example, price reduction information such as 10 yen / 1 MB (meaning that the selling price is reduced by 10 yen each time 1 MB of advertisement information is inserted) is displayed.

The purchaser considers the advertisement insertable area and the price reduction information displayed on the display means 14 and considers whether or not the recording medium (CD-R) on which data has been recorded is reused, etc. Set the range of the recording area where writing is permitted.

Next, the setting of the advertisement amount in the second processing of the advertisement insertion processing will be described. In the sales terminal 1, information on recording data is usually printed on a label surface of a recording medium (CD-R), and an advertisement can be inserted here by printing. However, when printing advertising information, although the purchase price can be reduced for the purchaser, the area for printing the recorded data on the label surface becomes smaller, and the information about the recorded data is read accordingly. There are inconveniences, such as difficulty in performing.

The purchaser sets the print area of the advertisement information on the label side in consideration of the degree of decrease in the purchase price and the degree of reading the information on the record data. In order to assist the purchaser in setting the advertisement information, the display unit 14 may display a preview of the print state of the label surface and a reduction amount of the purchase price at that time.

When the setting of the recording area in which the writing of the advertisement information is permitted as described above is detected in S33, the selling price of the sales data is calculated and the price is displayed on the display means 14 as the charging price (S34). In S32, if it is detected that the purchaser has performed the operation of not inserting the advertisement, the selling price at the fixed price is displayed as the charging price without performing the reduction processing.

Then, while waiting, the charge collecting means 15
Next, it is monitored whether or not money corresponding to the billing price has been paid (S35).

When it is confirmed that the charge has been paid to the charge collecting means 12, the communication means 7 sends a request signal corresponding to the purchase request and the advertisement amount permitted to be inserted to the data distribution server 2 via the Internet. Send (S3
6).

Then, the process waits until data is received from the data distribution server 2 (S37). Then, when the reception of the requested data (sales data and advertisement information) is confirmed, the received sales data is stored in the sales data storage means 8 and the advertisement information is stored in the advertisement information storage means 9 (S3).
8).

Next, the data distribution operation of the data distribution server 2 will be described with reference to the flowchart of FIG. First,
While waiting, the data distribution server 2 monitors whether or not a demand signal from each sales terminal 1 has been received by the sales terminal communication means 20. (S41). Then, when it is confirmed that the request signal has been received, the request signal is decoded to specify the requested sales data, whether or not the advertisement can be inserted, and the inserted advertisement amount. Then, a sales data calling signal is transmitted to the sales data information sources 3A to 3C in which the specified sales data is stocked. On the other hand, if the insertion of the advertisement is permitted, a call signal of the advertisement information corresponding to the inserted advertisement amount is transmitted to the advertisement information source 4 (S42).

After transmitting the calling signal of the sales data and the advertisement information, while waiting, the sales data information source 3A
It is monitored whether or not to receive the sales data and the advertisement information from 3C and the advertisement information source 4 (S43).

Upon confirming that the sales data has been received from the sales data information sources 3A to 3C and that the advertisement information has been received from the advertisement information source 4 (when the advertisement information can be inserted),
The sales data and the advertisement information are temporarily stored in the sales data temporary storage means 23 and the advertisement information temporary storage means 24 (S44). When the temporary storage of all requested sales data and advertisement information is completed, the data is transmitted to the requested sales terminal 1 via the sales terminal communication means 20 (S45), and a series of processing is ended. I do.

Next, the operation of the sales data information sources 3A to 3C will be described with reference to the flowchart of FIG. First, the sales data information sources 3A to 3C monitor whether or not a sales data calling signal has been received from the data distribution server 2 while waiting (S51). When the sales data call signal is received, the call signal is decoded to specify the desired sales data, and the sales data is extracted from the stocked data group (S52).

Then, the extracted sales data is transmitted to the data distribution server 2 (S53), and a series of operations is completed.

Next, the operation of the advertisement information source 4 will be described with reference to the flowchart of FIG. First, the advertisement information source 4 monitors whether or not an advertisement information calling signal has been received from the data distribution server 2 while waiting (S61). And
Upon receiving the advertisement information call signal, the call signal is decoded to specify the desired amount of advertisement information, and the advertisement information corresponding to the amount of advertisement information is extracted from the stock advertisement data group (S62).

Then, the extracted advertisement information is transmitted to the data distribution server 2 (S63), and a series of operations is terminated.

Next, the data selling operation by the selling terminal 1 will be described with reference to the flowchart of FIG.

First, a CD-R (recording medium) for writing is taken out from the recording medium stock means 11 and is conveyed to the writing means 10. Then, the sales data and the advertisement information stored in the sales data storage means 8 and the advertisement information storage means 9 are read out and written into the recording medium by the writing means 10 (S71).

When the writing is completed, the written recording medium is conveyed to the printing means 12. In the printing means 12,
The following print processing is performed. That is, text data and image data (such as data names and character data indicating details of data) stored in correspondence with the sales data, and text data and image data included in the advertisement information are stored in the sales data storage unit 8. Or from the advertisement information storage means 9 and print it on the label surface or the like of the written recording medium (S72). This printing process may be performed in advance before the writing process of the sales data and the advertisement information.

When printing is completed, the written recording medium is discharged to the discharge port 34 and delivered to the purchaser (S
73), a series of operations ends.

Next, the operation of the data distribution server 2 for collecting an advertisement fee will be described with reference to the flowchart of FIG. First, the advertisement payment collecting means 25 compares the total amount of advertisement insertion for a certain period (for example, every day, every week, every month) with each advertisement information source 4 (in this embodiment, a single advertisement for simplicity of explanation). (S81). Further, the advertisement fee collecting means 25 calculates an advertiser managing the advertisement information source 4 based on the total amount of the inserted advertisements (for example,
The advertisement price to be charged to the advertising agency for the above-mentioned fixed period is calculated (S82). Then, the advertisement fee collecting means 25
Transmits the information on the calculated advertisement price to the advertiser-side financial company 6 on a predetermined date and time (for example, a closing date) after the above-mentioned fixed period ends. Information on the advertisement price is transmitted to the advertiser-side financial company 6 via the financial company communication means 26 via a communication line (or the Internet) (S83). The advertiser-side financial company 6 that has received the information on the advertisement price pays the advertisement price with the seller-side financial company 5 by, for example, electronic settlement.

In the above-described embodiment, the advertisement information is taken in from the advertisement information source 4 every time each sales data is sold by the sales terminal 1. This has the advantage that the latest advertisement information can be taken in and inserted into the recording medium, but the transmission cost of the advertisement information is unavoidably increased. On the other hand, the advertisement information can be stored in advance in the advertisement information storage means 9 of the sales terminal 1 and inserted into the recording medium without updating the advertisement information for a certain period. In this case, although the latest advertisement information cannot be taken and inserted into the recording medium, the transmission cost of the advertisement information can be suppressed.

The location where the sales terminal 1 is installed is preferably in a downtown area where the number of people is as large as possible. Inevitable. In such a case, profits can be secured as follows. That is, in a downtown area or the like, the landowner where the sales terminal 1 is installed often runs a business that can be the advertiser described above. Therefore, when the landowner can be the advertiser, at least a part of the advertisement information inserted into the recording medium is the advertisement information of the landowner, thereby offsetting the advertisement price collected from the landowner and the land rent paid to the landowner. As a result, the rent that presses on profits can be kept low.

In the embodiment described above, the recording medium is C
Although the DR is used, it goes without saying that it may be an MD (mini-disc) or a DVD.

In addition, although the cash payment is made by cash payment, it goes without saying that a credit card or a prepaid card can be used.

Further, the portion to be printed by the printing means 8 may be not only the label surface of the CD-R but also a separately prepared paper. If it is music data, it can be printed as a lyrics card. It can also be printed as an album cover to be inserted and placed inside the case of a CD-R. In these cases, the purchaser may be asked if he / she wants to print image data such as a lyrics card, and the billing amount may be varied depending on whether or not he / she wants to print.

[0070]

As described above, according to the present invention,
By lowering the selling price of the recording medium in which the sales data has been written in accordance with the insertion of the advertisement, it is possible to increase the purchase motivation of the purchaser. Moreover, since the sales profit is compensated by the advertisement price collected from the advertiser, the sales profit does not decrease even though the sales price is lowered. For this reason, it is possible to reduce the sales price of data without reducing profits, thereby overcoming intensifying sales competition.
