DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a music game device that allows players to enjoy games similar to so-called slot machines.

In conventional slot machines, multiple sets of rotating number strings are stopped one after another and the players compete to see how well the stopped number strings match, and the game nature is considered only, with no consideration given to musicality.

An object of the present invention is to provide a music game device similar to a slot machine that has both gaming and musicality and allows players to practice their pitch sense and music reading skills while enjoying the game.

Therefore, the music game device according to the present invention displays a note on a musical staff using pitch data that is updated in chronological order, and as the note moves on the musical staff, a musical tone corresponding to the note is generated. By stopping the update of pitch data at the point in time, a plurality of notes can be sequentially stopped and displayed on the staff, and scores can be competed based on the combinations of the notes.

Hereinafter, the present invention will be explained with reference to the accompanying drawings.

FIG. 1 shows the external appearance of a portable keyboard electronic musical instrument incorporating a music game device according to the present invention, which, like the conventional keyboard electronic musical instrument of this type, has a keyboard 1, a speaker 2, a main switch 3, a volume/tempo The keyboard 1 is equipped with adjustment knobs 4 such as , select keys 5 for tone, rhythm, etc., and allows normal music performance using the keyboard 1 .

It is equipped with four stop switches 9 to 12 for stopping the movement of notes in a row.

As shown in an enlarged view in FIG. 2, the display 6 consists of a staff display 13 that displays notes corresponding to pitch data on a staff score, and a 4-digit score display 14 that digitally displays scores. .

The staff display 13 fixedly displays the staff and the treble clef, and also displays the display section at intervals in the left and right direction.
The four sets of note patterns 13a to 13d each represent a pitch of 11 notes from the _C3 note on the lower first line to the _F4 note on the fifth line. It is composed of.

Next, the basic configuration of a music game device incorporated into this keyboard electronic musical instrument will be explained with reference to FIG.

In this embodiment, a pitch data generator 20 is provided corresponding to each display section of the staff display 13 (a third
(Although only two are shown in the figure, if the staff display section of FIG. 2 is used, four will be required). The updating of the pitch data is sequentially stopped by update stopping means 21 which generates pitch data to be updated and is controlled by stop switches 9 to 12 in FIG.

Based on the pitch data generated by each pitch data generator 20, a musical tone generator 22 generates a musical tone signal having a pitch corresponding to the pitch data and outputs the sound from the speaker 2. In addition, the staff display 13 of the display 6
Note patterns 13a to 13 are shown in each display section of
Notes corresponding to each pitch data are displayed by d, and the display position moves upward or downward at fixed short time intervals.

Then, when the update of pitch data of each pitch data generator 20 is all stopped, all the note display on each display section on the staff display 13 is stopped, and the combination of each pitch data at this time is Accordingly, the determination circuit 23 determines the degree of matching, and displays the score on the score display 14 in order to make the determination result recognizable.

At this time, a musical tone corresponding to the judgment result of the judgment circuit 23 may be generated, for example, a fanfare sound or the like when all the judgment results match, and the sound may be emitted from the speaker 2.

Next, a more specific embodiment of the present invention will be described with reference to FIGS. 4 to 9.

In this embodiment, as shown in FIG. 4, four pitch data generation circuit blocks 24a to 24d and four latch timing pulse generation circuits 25a are provided corresponding to the four indicators of the staff display 13. ~
25d, and in addition to the parts shown in FIG. 3, a one-shot multi 26, a delay circuit 27,
A decoder 28 is provided.

Each pitch data generation circuit block 24a to 24
d are a pitch data generator 20 and a latch circuit 2, respectively.
8. Consists of a gate circuit 29, an address decoder 30, and a display data ROM 31. Of these, only one set of the address decoder 30 and display data ROM 31 may be provided in common to each pitch data generation circuit block 24a to 24d. good.

The pitch data generator 20 includes a random number generator 32 for generating an initial value of pitch data, and a pitch data update section 3.
3 and a latch circuit 34.

As shown in FIG. 5, the pitch data update unit 33 includes adders 41 and 42, addition data generators 43 and 44 that generate "1" and "-11" as addition data, respectively, and a comparison 45 and a comparison data generator 4 that generates "11" as comparison data.
6, and a selector 47.

In addition, the addition data "1" and "-11" and the comparison data "11" are both 2 by binary code.
It is output as a base number, and "1" to "11" are data corresponding to each pitch of _C3 to _F4 (excluding semitones).

Latch timing pulse generation circuits 25a to 25
A specific example of d is shown in FIG. 6, and a specific example of the determination circuit 23 is shown in FIG. An outline of the operation of the example will be explained.

When the game start switch 8 in Fig. 4 is turned on (it stays on only while the key is pressed), the input to the one-shot multi 26 becomes "1", and at the rising edge of the switch 8, a start pulse Sp is generated, and the staff In addition to resetting the displays on the display 13 and score display 14, the pitch data generation circuit block 2
The operations of the pitch data generators 20, etc. 4a to 24d and the latch timing pulse generation circuits 25a to 25d are started.

The pitch data generator 20 generates a start pulse Sp
In _response to _the input of Delayed start pulse Sp
When input to the latch circuit 34, the initial value of pitch data from the random number generator 32 is latched and output.

The pitch data output from the latch circuit 34 is returned to the pitch data update section 33, and as shown in FIG. It becomes the A input of the comparator 45, and is further inputted by the adder circuit 42 to "-".
11'' is added (that is, ``11'' is subtracted) and becomes the A input of the selector 47.

The comparator 45 outputs "0" while the A input does not exceed "11" of the B input, and outputs "1" when the A input exceeds "11". When the output of this comparator 45 is "0", the selector 47 outputs the B input, and the comparator 45
When the output becomes "1", the A input is output.

Therefore, the pitch data output from the selector 47 progresses downward from the _F4 pitch as the upper limit and the _C3 pitch as the lower limit, as shown in FIG. 8A.

Here, the addition data generated by the addition data generators 43 and 44 are set to "-1" and "+11" respectively, and the condition for the comparator 45 to output "1" is set as A<
When set to B, the pitch data output from the selector 47 advances upward with the pitch of _C3 as the lower limit and the pitch of _F4 as the upper limit, as shown in FIG. 8B.

Furthermore, if one more comparator is added to switch between up mode and down mode when the upper and lower limits are reached, downward and upward movement will be performed alternately as shown in Figure 8 (c). You can also get pitch data output that changes like an arpeggio.

Further, in this embodiment, semitones corresponding to black keys are excluded, but by changing the circuit shown in FIG. 5, pitch data corresponding to black keys can also be output. In that case, a semitone display using "#" or "♭" may be added to the staff display 13 shown in FIG. 2.

Returning to FIG. 4, the latch circuit 34 latches the initial data from the random number generator 32 only when the start pulse Sp is input, but thereafter the latch timing pulse Lp is input from the latch timing pulse generation circuits 25a to 25d. Each time, the pitch data from the selector 47 (FIG. 5) of the pitch data update section 20 is latched.

Therefore, the output of the pitch data generator 20, which is the output of the latch circuit 34, becomes pitch data that is updated in time series in synchronization with the latch timing pulse Lp.

This pitch data is transmitted to the latch timing pulse generation circuits 25a to 2 when the start pulse Sp is generated.
The pitch data is inputted to the musical tone generator 22 via the gate circuit 29 which is opened by the gate control signal Gs outputted from the gate control signal Gs outputted from the pitch data, and a musical tone signal corresponding to the pitch data is generated, and the musical tone is emitted from the speaker 2.

At the same time, the pitch data is decoded by the address decoder 30 and displayed in the display data ROM.
31 at the address of the display position corresponding to the staff display 13, and the note corresponding to the pitch data is displayed on the staff display 13 until the next pitch data is input.

Note that the pitch data generation circuit block 24a~
Musical notes corresponding to pitch data stored in each display data ROM 24d are displayed on each display section of the staff display 13 shown in FIG. 2, respectively. The position of the note displayed in each display section is
It changes sequentially (progressing downward in this embodiment) with the period of the latch timing pulse Lp.

So, when I turn on the stop switch 9,
The period of the latch timing pulse Lp from the latch timing pulse generating circuit 25a gradually becomes longer as shown in FIG. 9B, and eventually the latch timing pulse Lp is no longer output.

Therefore, the notes displayed on the display section of the staff display 13 will gradually move slowly from the point when the stop switch 9 is turned on, and will be displayed when the stop switch 9 is turned on one after another. The sound will stop at the pitch that was being played. After the musical tone corresponding to the stopped pitch position is sounded for about 1 second, the gate circuit 29 is activated by the gate control signal Gs.
is closed, and the generation of musical tones corresponding to the display section is stopped.

For example, if the stop switch 9 is turned on at the sound _D3 , the generation cycle of musical tones changes as shown in FIG. 9A and then stops.

Similarly, stop switches 10, 11, 1
2 is turned on in sequence, the latch timing pulse generation circuits 24b, 24c, and 24d sequentially lengthen the period of the latch timing pulse Lp and stop generating it when the period of the latch timing pulse Lp reaches "0", and the gate control signal Gs is set to "0". do.

Accordingly, each display section of the staff display 13 ~
The movement of each note displayed also stops at the pitch position when the respective stop switches 10 to 12 are turned on, and the generation of the corresponding musical tones also stops sequentially.

That is, the latch timing pulse generation circuit 2
5a to 25d, together with stop switches 9 to 12, serve as update stopping means for stopping updating of pitch data generated by each pitch data generator 20.

And each latch timing pulse generation circuit 2
5a to 25d set the stop signal _ST to "1" when the generation of the latch timing pulse Lp is completely stopped, and when all the stop signals _ST of the four circuits 25a to 25d become "1", the AND circuits 3
The output of 5 becomes "1".

As a result, the latch circuits 28 of the pitch data generation circuit blocks 24a to 24d each latch the pitch data being outputted from the pitch data generator 20 at that time and output it to the discrimination circuit 23.

The discrimination circuit 23 judges the degree of coincidence of the four input pitch data (A, B, C, and D), and the decoder 28 decodes the judgment result data and converts it into a score, which is displayed on the score display. 14.

Next, the latch timing pulse generation circuit 25a
A specific example of circuits 25d to 25d will be described with respect to the circuit 25a combined with the stop switch 9 shown in FIG.
The other three circuits are constructed in exactly the same way.

This latch timing pulse generation circuit 25a
includes a variable frequency oscillator 50, a latch circuit 60, a delay circuit 61, and a matching circuit 6 for controlling the same.
2 and set/reset type flip-flops 63 and 64, a falling differentiation circuit 65 for producing a gate control signal Gs, a delay circuit 66, and a flip-flop 67.

The variable frequency oscillator 50 includes an oscillation circuit 51 that generates frequency timing according to input data;
A latch circuit 52 that outputs data to this oscillation circuit 51, an initial value data generator 53, an addition data “+
This addition data "+" is added to the output data of the addition data generator 54 that generates "
It consists of an adder 55 that adds and outputs "n", and an AND circuit 56.

When the start pulse Sp is output from the one-shot multi 26 in FIG. 4, the flip- _flop 63 in FIG. At the same time, the latch data of the latch circuit 28 shown in FIG. 4 is erased.

At the same time, the start pulse Sp is input as a preset signal to the latch circuit 52 of the variable frequency oscillator 50, so the latch circuit 52 latches the initial value data generated by the initial value data generator 53 and outputs it to the oscillation circuit 51. do.

Thereby, the oscillation circuit 51 oscillates at a predetermined frequency according to the initial value data and outputs the latch timing pulse Lp to the latch circuit 34 in FIG. 4.

Thereafter, this state continues while the stop switch 9 is off, and the period of the latch timing pulse Lp remains constant as shown in period _T1 in FIG. 9B.

So, when I turn on the stop switch 9,
The flip-flop 64 is set to make its Q output "1", and the pitch data being generated by the pitch data generator 20 in FIG. Therefore, the B input data of the coincidence circuit 62 is delayed by one cycle of the latch timing pulse Lp.

The latch circuit 62 constantly receives new pitch data as A input data, and outputs a coincidence output "1" when A=B. That is, when the pitch data changes in sequence and the same pitch data as the pitch data that was being generated when the stop switch 9 was turned on is generated again, a coincidence output is produced.

By the way, when the Q output of the flip-flop 64 becomes "1", the AND circuit 56 activates the oscillation circuit 51.
, and outputs a latch signal to the latch circuit 52 every time the latch timing pulse Lp is output.

Therefore, the latch circuit 52 latches the data obtained by adding the addition data "+n" by the adder 55 to its own output data and outputs it to the oscillation circuit 51.

Therefore, the output data of the latch circuit 52 gradually increases, the oscillation frequency of the oscillation circuit 51 decreases accordingly, and the period of the generated latch timing pulse Lp gradually increases as shown in period _T2 in FIG. 9B. Become.

When the coincidence circuit 62 outputs a coincidence output "1" as described above, the flip-flop 63 is set and its Q output, the stop signal _ST , becomes "1".
Since the latch circuit 52 and the oscillation circuit 51 are reset and their operations are stopped, the latch timing pulse Lp is no longer generated.

The match output of match circuit 62 is also applied to latch circuit 6.
0 and flip-flop 64.
is also reset and its Q output is set to "0".

When the Q output falls, the falling differentiation circuit 65 generates a pulse, which is delayed by about 1 second in the delay circuit 66 and set by the start pulse Sp.
Flip-flop 67 whose output was set to “1”
and its Q output is the gate control signal.
Set Gs to “0”.

Thereby, the gate circuit 29 shown in FIG. 4 is closed and the generation of musical tones is stopped.

Next, a specific example of the determination circuit 23 will be explained with reference to FIG.

The determination circuit 23 shown in FIG. 7 includes six matching circuits 71 to 76, six inverters 77 to 82,
It is composed of eight AND circuits 83 to 90 and two three-input OR circuits 91 and 92.

FIG. 4 Pitch data generation circuit block 24a
If the pitch data latched in each latch circuit 28 in ~24d are A, B, C, and D, respectively, the matching circuit 71 operates as the matching circuit when A=B, and the matching circuit 72 operates as the matching circuit when A=C. 73 outputs "1" when A=D, the coincidence circuit 74 outputs "1" when B=C, the coincidence circuit 75 outputs "1" when B=D, and the coincidence circuit 76 outputs "1" when C=D.

Inverters 77-82 correspond to matching circuits 71-76.
2 of each matching circuit 71 to 76.
The output is set to “1” when two input data do not match.

AND circuit 83 corresponds to matching circuits 71, 72, 73.
Take the AND of the output of and obtain the four pitch data A to D.
The output is set to "1" only when all match.

AND circuit 84 ANDs the outputs of match circuits 71 and 72 and inverter 79; AND circuit 85 ANDs outputs of match circuits 71 and 75 and inverter 78; , 76 and the inverter 77, and the output is set to "1" only when three of the pitch data A to D match each other.

When the output of any of the AND circuits 84 to 86 becomes "1", the output of the OR circuit 91 becomes "1".

The AND circuit 87 ANDs the outputs of the coincidence circuit 71 and the inverters 78, 79, and 82;
79, 81, and the AND circuit 89 connects the matching circuit 76 and the inverters 77, 79,
81, and the output is set to "1" only when two of the pitch data A to D match each other.

When the output of any one of the AND circuits 87 to 89 becomes "1", the output of the OR circuit 92 becomes "1".

The AND circuit 90 connects inverters 77, 78, 7
9 is ANDed, and the output is set to "1" only when none of the pitch data A to D match.

These AND circuits 83, 90 and OR circuit 9
4 bit judgment data by output of 1,92
JD is formed, and this judgment data JD becomes “1000” when all pitch data A to D match, and 3
When one matches, it becomes "0100", when two matches, it becomes "0010", and when all match, it becomes "0001".

This judgment data JD is input to the decoder 28 and converted into a score display signal, and the score is displayed on the score display 14.

FIG. 10 is a block diagram of another embodiment of the present invention, in which parts corresponding to those in FIG. 4 are given the same reference numerals, and explanations of these parts will be omitted.

In this embodiment, the configuration is simplified by having one pitch data generator 20 and one latch timing pulse generating circuit 25, and only one stop switch is required.

The configuration of this embodiment will be explained below along with its operation.

A set/reset type flip-flop 101 is provided between the game start switch 8 and the one-shot multi 26, and when the game start switch 8 is turned on, the flip-flop 101 is set and its Q output becomes "1", and the one-shot is activated. The multi 26 outputs a start pulse Sp at the time of its rising edge.

This start pulse Sp is input to the latch timing pulse generation circuit 25 via the OR circuit 102, operates the latch timing pulse generation circuit 25 in the same way as in the previous embodiment, and also operates the random number generator of the pitch data generator 20. 32 is stopped to output initial value data, and at the same time, it is input to the latch circuit 34 as a preset signal to latch the initial value data generated by the random number generator 32.

Thereafter, the pitch data generator 20 updates the pitch data it outputs every time the latch timing pulse Lp is input, as described above.

The start pulse Sp is also input to the counter 104 via the OR circuit 103.
Change the count value from "0" to "1". This counter 104 is designed to self-reset counting up to "5".

The 3-bit count data from this counter 104 is input to a decoder 105. Decoder 1
In 05, when the count data is "1", only the output terminal is set to "1", and when the count data is "2", only the output terminal is set to "1".
The terminals that output "1" are sequentially shifted to → according to the count data.

In this embodiment, four gate latch circuits 106 are provided corresponding to each indicator of the staff display 13.
109 are provided, and each of the gate latch circuits 106 to 109 is controlled by the output signal from the output terminal 1 of the decoder 105, generated by the pitch data generator 20, and decoded by the decoder 110. The data for displaying musical notes is input respectively.

Therefore, when the count data of the counter 104 becomes "1" by the start pulse Sp,
When the output terminal of the decoder 105 becomes “1”,
The gate of the gate/latch circuit 106 is opened to allow the note display data from the decoder 110 to pass, and first, a note of a pitch corresponding to the initial value data is displayed on the display section of the staff display 13.

Thereafter, each time the pitch data generated from the pitch data generator 20 is updated, the displayed notes on the display section move upward or downward.

So, when I turn on the stop switch 9,
As mentioned above, when the period of the latch timing pulse Lp gradually becomes longer and the pitch data becomes uniform,
A stop signal _ST is output from the latch timing pulse generation circuit 25, and the one shot multi 111
The rising pulse is output from and input to the shift register 112.

Thereby, the shift register 112 latches the pitch data at that time. Also, the pulse from this one-shot multi 111 is output to the OR circuit 10.
3, the counter 104 counts up through the decoder 105, and the output terminal of the decoder 105 becomes "0" and then becomes "1", but when the output terminal falls, the gate latch circuit 106 changes the current value of the decoder 11.
Latch the note display data starting from 0 and continue displaying the note.

At the same time, the pulse from the one-shot multi 111 is passed through the OR circuit 102 to the pitch data generator 2.
0 random number generator 32 and latch circuit 34, and also input it to the latch timing pulse generation circuit 25 to generate the latch timing pulse Lp,
Generation of new pitch data and its chronological update begin.

The pitch data is displayed on the display section of the staff display 13 through the gate latch circuit 107.

Then, when the stop switch 9 is turned on again, the gate latch circuit 107 latches the current note display data to fix the displayed note on the display, and the shift register 112 transfers the previously latched pitch data to the next output line. Along with the shift,
Newly latch the pitch data at that time.

In this way, by turning on the stop switch 9 four times, one note can be selected and fixedly displayed on each display section of the staff display 13. Then, pitch data corresponding to the notes displayed on the display sections is sequentially shifted and stored in the shift register 112.

At this time, the output terminal of the decoder 105 becomes "1", so the latch circuit 113 latches the four pitch data stored in the shift register 112 and outputs it to the determination circuit 23.
Reset flip-flop 101.

Judgment and score display by the judgment circuit 23 are the same as in the previous embodiment.

FIG. 11 is an external view of an embodiment in which the music game device according to the present invention is incorporated into a calculator.

The display 6' in this embodiment also includes a staff display 13' and a score display 14', but the score display 14' has a large number of digits because it is also used to display numerical values for calculations.

In addition to the calculation keys, a mode switching key 7', a game start key 8', and a speaker or piezoelectric buzzer 2' are provided. Stop key 9'~
12' is also used as a calculation key (it serves as a stop key only in game mode).

Further, as shown in the embodiment, it is convenient to incorporate it into a portable keyboard electronic musical instrument or a calculator, and since many parts can be shared, it can be implemented at low cost.

Furthermore, by using a microcomputer, the circuit configuration can be made extremely simple.

As described above, the music game device according to the present invention is configured such that multiple types of musical notes that are updated in chronological order are displayed and moved on the staff, and the corresponding sounds are output. By stopping at the right timing, you can enjoy the game like a slot machine, and it is also visually and audibly fun.You can learn the correspondence between sounds and notes while enjoying the game, and it is also effective in teaching pitch sense and music reading ability. It will be done.
