==About the processing in the karaoke system==
Next, processing in the karaoke payment system 1 according to this embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing processing in the karaoke payment system 1. As shown in FIG. In this example, it is assumed that a user U who uses a karaoke store N wishes to sing a song X in karaoke.

A store clerk C at a karaoke store N registers the song ID of the song X through the input means 13 of the store terminal R. The reservation instructing unit 15a transmits the registered music ID to the karaoke apparatus K, and instructs it to reserve the performance of the music X (instruct performance reservation; step 10). The karaoke machine K registers the received song ID in the reservation queue.

When receiving a signal from the karaoke machine K indicating that the music piece X is waiting to be played, the first generation unit 15b reads out the first amount information and the first payee information for the karaoke store N from the storage means 10 . The first generator 15b encodes the read information and generates a first code for the first payment (generates a first code for the first payment; step 11).

The first display control unit 15c causes the display means 12 to display the first code generated in step 11 (display the first code, step 12). The clerk C presents the displayed first code to the user U.

The user U photographs the first code through the photographing means 24 of the user terminal M. FIG. The first acquisition unit 25a acquires the first amount information and the first payee information by reading and decoding the first code from the captured image (obtains the first amount information and the first payee information; step 13).

The first payment instructing unit 25b instructs the server device S to make a payment based on the first amount information and the first payee information (instructs the first payment; step 14).

The server device S performs payment processing based on the instruction from the first payment instruction unit 25b. After that, the server device S transmits to the store terminal R of the karaoke store N a notification that the first payment has been made.

When receiving notification from the server device S that the first payment has been made (Y in step 15), the performance instruction unit 15d instructs the karaoke device K to start karaoke performance of the song X (instruct to start karaoke performance; step 16). Based on the instruction, the karaoke machine K starts karaoke performance of the piece of music X in the standby state. The user U can sing karaoke along with the karaoke performance. On the other hand, if there is no notification from the server S that the first payment has been made (N in step 15), the store terminal R does not instruct the karaoke machine K to start karaoke performance.

As is clear from the above, the karaoke payment system 1 according to the present embodiment is communicably paired with the karaoke device K installed in the karaoke store N, and has a store terminal R operated by the store clerk C of the karaoke store N and a user terminal M owned by the user U of the karaoke store N. The store terminal R includes a reservation instructing unit 15a for instructing the karaoke machine K to make a reservation for a musical piece that the user U desires to sing in karaoke; It has a first display control part 15c for displaying the first code on the display means 12 of the shop terminal R, and a performance instruction part 15d for instructing the karaoke machine K to start playing karaoke of the reserved music when the first payment is made. The user terminal M has a first acquisition unit 25a that reads a first code displayed on the display means 12 of the shop terminal R and acquires first amount information and first payee information included in the first code, and a first payment instructing unit 25b that instructs the server device S to make a first payment based on the acquired first amount information and first payee information.

According to such a karaoke system 1, a karaoke performance is performed only when payment is received from a user after making a reservation for performance of a musical piece. Therefore, the karaoke parlor can reliably charge "advance payment". That is, according to the karaoke payment system 1 according to the present embodiment, it is possible to coordinate the reservation of the music performance, the payment for the karaoke performance, and the start of the karaoke performance of the music.

<Second embodiment>
Next, a karaoke payment system according to the second embodiment will be described with reference to FIGS. 5 to 7. FIG.

Some users wish to sing karaoke only a part of a song (for example, only No. 1). In such a case, even if the karaoke store being used charges according to the number of songs, it is common for the user to want to pay only for the number of karaoke songs sung. Therefore, in the present embodiment, a configuration will be described in which part of the amount once paid is refunded. A detailed description of the configuration similar to that of the first embodiment will be omitted.

== User terminal ==
The configuration of the user terminal M according to this embodiment will be described with reference to FIG. As shown in FIG. 5, when the user U activates the payment application in the present embodiment, the control unit 25 functions as a first acquisition unit 25a, a first payment instruction unit 25b, a second generation unit 25c, and a second display control unit 25d.

(Second generator)
The second generation unit 25c generates a second code for the second payment for refunding part of the amount paid in the first payment, based on the second payment destination information indicating the payment destination specified by the user.

The second payee information indicates the payee when the karaoke parlor makes a refund to the user. The second payee information is, for example, the bank account number with which the user U has a contract. The second payee information is stored in the storage means 20 of the user terminal M or the like. The second settlement means that the karaoke store refunds a part of the amount paid when starting the karaoke performance of the reserved song to the user who sings the karaoke song. The second code is a dedicated code used for the second payment. The second code is, for example, a one-dimensional code similar to the first code.

For example, in the example of the first embodiment, assume that the user U wants to stop the karaoke performance in the middle of the karaoke performance of the song X. In this case, the user U instructs the clerk C of the karaoke store N to stop the karaoke performance. On the other hand, the user U instructs the refund processing on the payment application. In this case, the second generator 25c reads the second payee information from the storage means 20. FIG. The second generator 25c encodes the read information to generate a second code for the second payment.

(Second display control unit)
The second display control unit 25d displays the generated second code on the display means of the user terminal.

In the above example, the second display control unit 25d causes the display unit 12 to display the second code generated by the second generation unit 25c.

== Store terminal ==
The configuration of the store terminal R according to this embodiment will be described with reference to FIG. As shown in FIG. 6, in the present embodiment, the control unit 15 functions as a reservation instruction unit 15a, a first generation unit 15b, a first display control unit 15c, a performance instruction unit 15d, a cancellation processing unit 15e, a second acquisition unit 15f, and a second payment instruction unit 15g.

(Cancellation processing part)
A stop processing part 15e instructs the karaoke machine K to stop the karaoke performance of the music when receiving a signal indicating the stop of the karaoke performance of the music, and calculates the refund amount to be refunded to the user according to the singing section of the music during which the karaoke performance is stopped among the singing sections of the music.

The singing section of a song is a section with lyrics included in the performance section in which karaoke performance is performed. The singing section may be roughly divided into, for example, the first singing section and the second singing section, or may be subdivided into the first A melody, the first B melody, and the first chorus. A singing section is set in advance for each piece of music. In the following explanation, it is assumed that the piece of music X is composed of four singing segments.

For example, in the example of the first embodiment, assume that the user U wants to stop the karaoke performance when the karaoke performance of the song X reaches the third singing section. In this case, the user U instructs the clerk C of the karaoke store N to stop the karaoke performance. The store clerk C inputs karaoke performance stop via the input means 13 of the store terminal R. The stop processing unit 15e receives a signal indicating stop of the karaoke performance based on the input. In this case, the stop processing unit 15e instructs the karaoke machine K to stop playing the song X in karaoke. The karaoke machine K stops karaoke performance of the song X based on the instruction.

On the other hand, the cancellation processing unit 15e calculates the refund amount to be refunded to the user according to the singing section of the song X in which the karaoke performance is canceled.

For example, the cancellation processing unit 15e can calculate the refund amount by multiplying the paid amount by the ratio of the number of characters corresponding to the singing section in which the karaoke performance was not performed, out of the number of characters in all the singing sections of the song.

For example, assume that the amount paid by the user U in the first payment is 100 yen. Also, suppose that the number of characters in four singing segments is 480 characters, and the number of characters in one singing segment is 120 characters. In this case, the cancellation processing unit 15e calculates 100 yen×(120 characters÷480 characters)=25 yen as the refund amount.

In addition, instead of the number of characters in the singing section, the ratio of the singing section in which the karaoke performance was not performed may be used among all the singing sections. In the case of the above example, the cancellation processing unit 15e calculates the refund amount as follows: 100 yen x (singing section (one) in which karaoke performance was not performed/all singing sections (four)) = 25 yen.

(Second Acquisition Unit)
The second acquisition unit 15f reads the second code displayed on the display means of the user terminal and acquires the second payee information included in the second code.

For example, assume that the display means 22 of the user terminal M displays the second code generated by the second generator 25c.

A store clerk C of the karaoke store N operates the input means 13 to activate the code reader, and photographs the second code through the photographing means 14 . The second acquisition unit 15f reads the second code from the captured image. The second acquisition unit 15f acquires the second payee information by decoding the read second code.

(Second settlement instruction unit)
The second payment instructing unit 15g instructs the server device to perform the second payment based on the calculated refund amount and the obtained second payee information.

Based on the instruction from the second payment instructing unit 15g, the server device S deposits the amount corresponding to the refund amount from the account of the karaoke store N to the account of the user U indicated by the second payee information.

==About the processing in the karaoke system==
Next, the processing in the karaoke payment system 1 according to this embodiment will be described with reference to FIG. FIG. 7 is a flow chart showing processing in the karaoke payment system 1. As shown in FIG. In this example, it is assumed that the user U who uses the karaoke store N performs karaoke singing of the song X after paying a predetermined amount of money by the process described in the first embodiment.

When the user U gives an instruction to stop the karaoke performance, the store clerk C of the karaoke store N gives an instruction to stop the karaoke performance of the song X through the input means 13 of the store terminal R.

When the stop processing unit 15e receives the signal indicating the stop of the karaoke performance of the song X, it instructs the karaoke device K to stop the karaoke performance of the song X (instructs to stop the karaoke performance; step 20). The karaoke machine K ends the karaoke performance of the song X based on the instruction.

After that, the cancellation processing unit 15e calculates the refund amount to be refunded to the user according to the singing section for which the karaoke performance is canceled among the singing sections of the song X (calculation of the refund amount; step 21).

On the other hand, the user U who instructed to stop the karaoke performance instructs the refund processing on the payment application. In this case, the second generator 25c reads the second payee information from the storage means 20. FIG. The second generator 25c encodes the read information and generates a second code for the second payment (generates a second code for the second payment, step 22).

The second display control unit 25d causes the display means 22 to display the second code generated in step 22 (display the second code, step 23). The user U presents the displayed second code to the clerk C.

The store clerk C photographs the second code through the photographing means 14 of the store terminal R. The second acquisition unit 15f acquires the second payee information by reading and decoding the second code from the captured image (acquiring the second payee information, step 24).

The second payment instructing unit 15g instructs the server device S to make a payment based on the calculated refund amount and the second payee information (instructs the second payment; step 25).

The server device S performs payment processing based on the instruction from the second payment instruction unit 15g.

As described above, in the karaoke payment system 1 according to the present embodiment, the user terminal M has a second generation unit 25c for generating a second code for the second payment for refunding part of the amount paid in the first payment based on the second payment destination information indicating the payment destination specified by the user U, and a second display control unit 25d for displaying the generated second code on the display means 22 of the user terminal M. In addition, when the store terminal R according to the present embodiment receives a signal indicating that the karaoke performance of a song is to be stopped, the store terminal R instructs the karaoke device K to stop the karaoke performance of the song, and calculates the refund amount to be refunded to the user according to the singing section in which the karaoke performance is stopped among the singing intervals of the song. 15f, and a second payment instructing unit 15g for instructing the server device S to perform the second payment based on the calculated refund amount and the obtained second payee information.

According to such a karaoke payment system 1, if the karaoke performance is canceled halfway after the payment for the karaoke performance has been made, part of the paid amount can be refunded. That is, even if the karaoke performance is stopped halfway, it is possible to pay an appropriate amount of money according to the singing section in which the karaoke singing has been performed so far.

<Modification>
In the second embodiment, an example was described in which a refund is made each time in response to an instruction to stop the karaoke performance from the user. On the other hand, depending on the user, there may be a case where the instruction to stop the karaoke performance in the middle of the karaoke performance is issued multiple times in one use of the karaoke parlor N. In such a case, it is troublesome for the user terminal to generate the second code each time and for the shop terminal to read the second code each time. Therefore, according to the karaoke payment system in this modified example, it is possible to collectively make refunds for multiple cancellations of karaoke performances at once.

In this case, the reservation instructing unit 15a causes the storage unit 10 to store the music identification information for identifying the music and the user identification information indicating the user who wishes to sing karaoke of the music in association with each other. For the user identification information, for example, information provided in the store terminal R for customer management can be used.

For example, assume that user U wishes to sing song X in karaoke. In this case, the reservation instructing unit 15a associates the song ID of the song X with the user ID of the user U and causes the storage means 10 to store the song ID. Similarly, assume that user U wishes to sing song Y in karaoke. In this case, the reservation instructing unit 15a associates the music ID of the music Y with the user ID of the user U and causes the storage means 10 to store the music ID.

The cancellation processing unit 15e stores the refund amount calculated for each song in association with the user identification information.

For example, it is assumed that the user U gives an instruction to stop playing music X and music Y in the middle of the karaoke performance. In this case, the cancellation processing unit 15e calculates the refund amount RaX for the song X and the refund amount RaY for the song Y. The cancellation processing unit 15e causes the storage unit 10 to store the refund amount RaX and the refund amount RaY in association with the user ID of the user U.

The second payment instruction unit 15g instructs the server device to perform the second payment based on the total amount of the refund associated with the obtained second payee information and the user identification information.

For example, when the user U leaves the karaoke shop N, the user U instructs a refund process on the payment application. In this case, the second generator 25c reads the second payee information from the storage means 20. FIG. The second generator 25c encodes the read information to generate a second code for the second payment. The second display control unit 25d causes the display unit 22 to display the second code generated by the second generation unit 25c.

A store clerk C of the karaoke store N operates the input means 13 to activate the code reader, and photographs the second code through the photographing means 14 . The second acquisition unit 15f reads the second code from the captured image. The second acquisition unit 15f acquires the second payee information by decoding the read second code.

Also, the store clerk C designates the user ID of the user U who instructed the refund processing at the store terminal R, and the second acquisition unit 15f reads the refund amount linked to the user ID of the user U from the storage means 10. - 特許庁In the above example, the user ID of the user U is associated with the refund amount RaX and the refund amount RaY. The second acquisition unit 15f adds up the read refund amounts to calculate the total amount RaX+RaY.

The second payment instruction unit 15g instructs the server device S to perform payment based on the total amount and the second payee information.
