However, the conventional musical tone information input device cannot grasp the correspondence between the pitch position of the musical note in the musical score and the position of the key on the keyboard. For this reason, there is a problem that, for an infant whose skill and knowledge have been improved to some extent, a device for inputting musical sound information using a group of push-button switches is not sufficient, and further improvement cannot be expected. On the other hand, if the transition is made to the keyboard instrument at this stage, it is not possible to visually grasp the pitch to be pronounced and its pitch position. For this reason, there is a problem that it is difficult to learn as a music education device for infants. The problem of the present invention is that children who come into contact with music for the first time
It is an object of the present invention to realize a musical sound information input device that can be effectively used for music education, even for infants whose skills and knowledge have improved to some extent, and even for beginners of adults.

Or, a control unit that outputs the first drive signal. According to the present invention, when the first input device is operated, the pitch of the sound generated based on the operation is determined, and the operation device of the second input device corresponding to the operation device related to the operation is displaced. A second drive signal is output to the second operator displacement means. On the other hand, when the second input means is operated, the pitch of the sound generated based on the operation is determined, and the first operation of displacing the operation element of the first input means corresponding to the operation element related to the operation is performed. A first drive signal is output to the child displacement means.

19) If #HSW is ON, the flag #HF is set to 1 (step S120). Step S11
If #HSW is off at # 9, #HF is set to 0
Is set (step S121), and it is determined whether or not another modulation symbol switch 記号 HSW is on (step S122). If the $ HSW is on, the flag $ HF is set to 1 (step S123),
If $ HSW is off, $ HF is set to 0 (step S124).

After setting #HF in step S120, or in step S123 or step S12
After setting $ HF in 4, it is determined whether or not #SW, which is a temporary symbol switch, is on (step S125). If #SW is on, flag #F
Is set to 1 (step S126). On the other hand, #SW
Is off, #F is set to 0 (step S
127), it is determined whether or not the accidental switch $ SW is ON (step S128). If the $ SW is on, the flag $ F is set to 1 (step S1).
29). On the other hand, if $ SW is off, $ F is set to 0 (step S130), and the accidental switch N
It is determined whether or not the SW is on (step S13)
1). Then, if NSW is on, NF is set to 1 (step S132), and if NSW is off, NF is set to 0 (step S133).

After setting #F in step S126 and setting $ F in step S129,
Alternatively, after setting NF in step S132 or step S133, the process proceeds to step S134 in FIG. In step S134 of FIG. 19, the pointer m is set to 1, and the following loop processing is executed while incrementing m. It is determined whether or not the S (m) SW has been operated (step S135), and when it has changed from OFF to ON, the flag SF (m) is set to 1 (step S136), and SF (m), #HF , @HF, #
The corresponding key number K (n) is detected from F and $ F (step S137).

In the process of detecting K (n) in step S137, as shown in FIG. 20, the key number K (n) of the white key corresponding to SF (m) is detected from the table of ROM 11 (step S138). It is determined whether or not #F is 1 (step S139). If #F is 0, ΔF
Is determined to be 1 (step S140). ♭
If F is 0, it is determined whether or not #HF is 1 (step S141). When #HF is 1, it is determined whether or not S (m) is the pitch related to the modulation symbol (step S142). If the pitch is related to the modulation symbol, it is determined whether or not NF is 0 (a state without a natural accidental symbol) (step S143).
If F is 0, K (n) is incremented to raise the pitch by a semitone (step S144).

If #HF is 0 in step S141, it is determined whether or not ♭ HF is 1 (step S). If ♭ HF is 1, it is determined whether S (m) is a pitch related to a modulation symbol (step S1).
46). If the pitch is related to a modulation symbol, NF is 0
Is determined (step S147), and NF is 0.
If, K (n) is decremented to lower the pitch by a semitone (step S148). If #F is 1 in step S139, K (n) is incremented in step S144 to increase the pitch by a semitone.
If ΔF is 1 in step S140, K (n) is decremented in step S148 to lower the pitch by a semitone.

In the flow of FIG. 20, #F, $ F, #
If both HF and ♭ HF are 0, K (n) is the key number K (n) of the white key detected from the table of the ROM 11 in step S138. Even if either #HF or ♭ HF is 1, even if S (m) is not the pitch related to the modulation symbol, or if it is the pitch related to the modulation symbol, N
When F is 1 (a state with a natural accidental symbol), K (n) is the key number K (n) of the white key detected from the table of the ROM 11.

After K (n) is detected by the flow of FIG. 20, the flow shifts to step S149 of FIG. 19 to set the flag KF (n) to 1. When S (m) SW changes from ON to OFF in step S135,
SF (m) is set to 0 (step S150), and SF
(M), a corresponding key number K (n) is detected from #HF, $ HF, #F, $ F (step S151). K (n)
Is the same as the flow shown in FIG. Thereafter, KF (n) is set to 0 (step S15).
2).

Step S149 or step S15
In step 2, after the flag KF (n) is set, or when S (m) SW does not change in step S135, m is incremented (step S153), and m is incremented.
Is greater than the maximum number (step S15).
4). If m is equal to or less than the maximum number, step S13
5 and the loop processing up to step S154 is repeated. When m exceeds the maximum number in step S154, the process returns to the main flow.
