DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is embodied in a known karaoke apparatus will be described below with reference to FIGS.

As shown in FIG. 1, in the karaoke apparatus 20 of this embodiment, a fee collecting device 1 for collecting a fee.
Is connected to the reproducing apparatus 2 via the reproduction permission signal line 3 and the reproduction time measuring signal line 4. The playback device 2 has a plurality of laser discs (not shown) in which a plurality of songs are recorded. In addition, the playback device 2 includes an operation panel 5 having a plurality of keys for selecting and playing a desired song from the songs recorded on the laser disc.
And the well-known microphone 6 and amplifier 7 are connected,
The output of the amplifier 7 is connected to the speaker 8.

As shown in FIG. 2, the charge collection device 1 has an output port 12 connected to the reproduction permission signal line 3.
And a well-known CPU 10 connected to the input port 13 connected to the reproduction time measurement signal line 4, and a CPU 1.
A timer 11 which is connected to 0 and keeps track of the playing time of music.
And a well-known collection mechanism 15 for collecting the karaoke fee by a coin, a bill, a prepaid card, or the like, which is connected to the CPU 10 through the interface 14.
And the display 16 for displaying the balance, and the CPU 10.
And a ROM 17 storing the operation program of the above. If the collecting mechanism 15 has a balance of coins, bills, or prepaid cards, the CPU 10 maintains the reproduction permission signal line 3 at the Hi level, and permits the reproduction device 2 to reproduce the music. In addition, the timer 11 is a CP
The reproduction time measuring signal line 4 input to U10 is Hi.
When the level is maintained, do a time count.

When using the karaoke device 20 having such a structure, the user of the karaoke device 20 inserts a coin, a bill, a prepaid card or the like into the collecting mechanism 15 of the charge collecting device 1, and then, from the operation panel 5. Enter the song you want to play. Then, when the start key provided on the operation panel 5 is pressed, the reproducing device 2 reproduces the music specified by the operation panel 5. Then, the reproduced music is amplified by the amplifier 7 and output from the speaker 8. Therefore, the user of the karaoke device 20 inputs a singing voice from the microphone 6 in accordance with the music output from the speaker 8. The input singing voice is mixed with the music reproduced by the reproducing device 2, amplified by the amplifier 7, and then output from the speaker 8.

Now, with reference to FIGS. 3 and 4, a charge collecting method by the charge collecting device 1 of the karaoke device 20 of the present embodiment will be described.

In the collecting mechanism 15, coins, bills, prepaid cards, etc. are inserted and deposited (S1).
Then, the CPU 10 of the fee collection device 1 resets the timer 11 (S2), sets the reproduction permission signal line 3 connected to the reproduction device 2 through the output port 12 to the Hi level, and permits the reproduction device 2 to reproduce. A signal is output (S5).
When a music piece to be reproduced is designated by the operation panel 5 while the Hi level reproduction permission signal is being input, the reproduction apparatus 2 reproduces the music piece by pressing the start key, and During reproduction, the reproduction time measurement signal line is set to Hi level, and the reproduction time measurement signal is output to the CPU 10 via the input port 13 of the fee collection device 1 (S8, YES). Then, in the fee collection device 1,
The time during which the reproduction time measurement signal is input to the CPU 10 is counted by the timer 11 (S9), and the balance of coins, banknotes, prepaid cards, etc. inserted into the collection mechanism 15 is initially reduced according to the count value. Go (S1
0, S11).

In this way, there is a balance (S4 ・ YE
S), H from the CPU 10 of the charge collecting device 1 to the reproducing device 2
While the i level reproduction permission signal is being output (S5), the reproducing apparatus 2 reproduces the music specified by the operation panel 5. However, as the music is reproduced, the balance of coins, bills, prepaid cards, etc. inserted in the collection mechanism 15 is gradually reduced, and when the balance becomes 0 (S4, NO), the CPU 10 causes the reproduction device to reproduce. The reproduction permission signal output to No. 2 becomes Low level (S
7) Therefore, even if the reproducing apparatus 2 is reproducing the music, as shown in FIG. 3, the reproduction of the music is interrupted midway. It should be noted that if the display 16 reveals that the balance is running low while the music is being played, further payment may be made, or if the use of the karaoke device 20 is stopped while the balance is still present, The balance is returned as fishing, or the balance is written in the prepaid card (S3). At this time, if the balance has a fraction, the fraction is rounded up, rounded down, or rounded off. As a result, regardless of whether a short piece of music is played or a long piece of music is played, a charge is collected according to the playing time, so that an unfair feeling caused by a difference in playing time can be eliminated.

Further, when the musical tone information of different musical pieces is connected by MIDI to form a so-called medley type musical piece and the musical piece is reproduced, the above-mentioned charge collecting method is particularly effective. Become.

The present invention is not limited to the above-mentioned embodiments, and various modifications can be made without departing from the spirit of the invention.

For example, instead of calculating the charge in proportion to the reproduction time, the charge table corresponding to the reproduction time may be referred to.

[0017]

As is clear from the above description,
According to the music reproducing device of the present invention, since the charge is calculated based on the reproduction time of the music, the charge can be collected fairly regardless of the length of the reproduction time of the music to be reproduced.
