The created key code is then supplied to the musical tone signal generation circuit 13, where a musical tone signal of a scale corresponding to the key code is generated, and the speaker SP is driven.

[Problems to be Solved by the Invention] By the way, the finger switch provided in the detector section applied to the conventional musical tone generating device described above uses a flat thin plate in its configuration, so that it is difficult to play. When a person wears a mounting device, the point at which the thin plate bends (hereinafter referred to as the bending point) changes depending on how the device is worn. Therefore, it is necessary for the performer to confirm in advance the bending angle of the finger at which each finger switch is turned on. In addition, finger switches are composed of thin plates, cylinders, springs, movable pieces, gate members, push button switches, etc., so they have a thin structure and have to be manufactured with different sizes for the fingers. There was also the problem of high costs.

The present invention has been made in view of the above-mentioned circumstances, and has a musical tone control having a detecting section that can always keep the bending point at a constant position regardless of the wearing state of the attachment, and can have a simple structure. The purpose is to provide the device.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a support member formed in a shape that fits along the palm or back of a human hand excluding fingers, and a support member provided on the support member. The finger rest is shaped to fit along the long direction of the flat or back side of the finger (

[Operation] According to the present invention, by bending the finger, the finger rest member is bent from the notch. Then, when the fingering member is bent to a predetermined angle, the conductive members provided on opposite sides of the notch come into contact and become electrically conductive.

As a result, the switch means is turned on, and musical tone control information is generated based on the output signal of this switch means.

Further, a detection unit DQ for the left hand (not shown) is similarly configured, and each finger rest member is provided with a joint switch shc.

~S h12s is provided.

Next, the configuration of the right-hand mounting tool FHr will be explained.

FIG. 8 is a plan view showing the external configuration of the right-hand mounting tool FHr, and FIG. 9 is a side view of FIG. 8.

As shown in these figures, the mounting tool FHr has a double structure in which an insertion portion FHra into which the detector SHr is inserted is provided on the palm side. A hook-and-loop fastener 37 formed to a predetermined size is attached inside this insertion portion F1-(ra. This hook-and-loop fastener 37 is connected to the hook-and-loop fastener 17 attached to the detector SHr shown in FIG. The mounting tool FHr is constructed in this manner, and the mounting tool FHQ for the left hand (not shown) is constructed in substantially the same manner.

As described above, in the detection part Dr composed of the detector SHr and the attachment device FHr, after the performer wears the detection part Dr on his right hand, for example, as shown in FIG. When bending from this state, the finger rest member 20
is bent from the notch 25, which is formed thinner than other parts. Then, as shown in FIG. 10 (b), the notch 25
When the upper part of the finger rest member 20 is bent to a predetermined angle, the blocks 30 and 3 of the joint switch 5hr2 are bent.
1 and the end faces of block 28 and block 29 are in contact with each other. This brings the contact portion 33b and the contact portion 34b into electrical continuity. Next, as shown in FIG. 1O (c), when the finger is further bent from the state where the contact portions 33b and 34b are electrically connected, the finger rest 20 is made of a flexible material, so the intervening portion 20 itself begins to curve. therefore,
Excessive stress is not applied to the contact portions 33b and 34b, and these contact portions are not damaged.

The on/off state of g is input, and the timbre set by the timbre setting switch 14 is input manually as the timbre code TC.

Next, a key code KC is created based on the input on/off state and code TC. Here, FIG. 12 shows each joint switch S hr + ~ when the set tone of the tone setting switch 14 corresponds to the saxophone.
S hrs on/off status? g (○: on/×: off)
The key code generation circuit 12 generates a key code KC corresponding to one of the scales C, SI, E, F, G, U, C, and C according to each finger operation. Create. In this case, the key code generation circuit 12 changes the number of octaves according to the on/off state of the joint switch ShQ by bending the thumb of the left hand, and changes the value of the key code KC. Further, FIG. 13 shows the relationship between each joint switch Shr+ to Shrs and the musical scale when the set tone of the tone setting switch 14 is made to correspond to a trumpet, which is different from the case where the set tone is a saxophone. Then, the key code generation circuit 12 sequentially outputs the created key code KC to the musical tone signal generation circuit 13. Musical tone signal generation circuit! 3 is a musical scale corresponding to the key code KC inputted from the key code generation circuit 12, and generates a musical tone signal having a tone corresponding to the code TC to drive the speaker SP.

In the above configuration, when the performer sets the saxophone tone or trumpet tone using the tone setting switch 14, the musical tone signal generating circuit 13 inputs the set tone as the tone code TC and switches the tone of the generated musical tone. Furthermore, when the performer performs finger operations as shown in FIG. 12 or 13 for each gradation of the music being played, a melody sound having a saxophon or trumpet tone is generated from the speaker SP. That is, by setting the timbre according to the desired musical instrument, it is possible to play the musical instrument with exactly the same operations as when operating a real musical instrument.

In addition, in the above embodiment, the finger rest members Shr+ to Sh
Since rs is formed into a curved shape, the ability to hold the finger is improved and the finger does not easily come off from the finger rest member. Furthermore, in the above embodiment, since the detector S) [r is placed against the palm of the hand, there is an advantage that each of the finger rest members Shr+ to Shrs can be easily pressed intuitively.

Further, in the above embodiment, the detector SHr and the mounting tool F

■1 r can be attached to and detached from the mounting tool FHr.

Therefore, there are advantages that the detector SHr can be replaced and the mounting tool FHr can be washed. In addition, because hook-and-loop fasteners have a planar shape, the fasteners can be connected with a slight offset between them, so it has the advantage of being able to handle differences in the size and shape of the hands of individual performers. can get.

Further, in the above embodiment, the detection section is placed on the palm of the hand, but it may be placed on the back of the hand. FIG. 14 is a perspective view showing the configuration of the finger rest member in this case, and as shown in the figure, the cross-sectional shape of the surface that contacts the finger is curved along the back of the finger, so that the finger can be easily inserted. It is designed not to come off. Note that the parts other than the above-mentioned parts are formed almost the same as the detector SHr described earlier. In addition, the mounting tool for inserting this detection part is the mounting tool FH mentioned above.
Like r, it has a double structure, and an insertion part into which a detection part is inserted is provided on the upper side.

Providing the detection section on the back of the hand in this manner provides the advantage that the performer can also hold other objects (musical instruments, microphones, etc.) at the same time.

Next, FIG. 15 is an external configuration diagram when a musical tone control device according to another embodiment of the present invention is attached to a player. This device is composed of a belt-shaped musical tone control information generating section 38, a right-hand detection section 39, and a left-hand detection section 40. The detecting sections 39 and 40 have substantially the same structure as the detecting section Dr described above, and are connected to the tone control information generating section 38 via a cable and a connector (not shown).

The musical tone control information generating section 38 has a key code generating circuit that converts the output of the detecting section 39 and 40 into a key code, and a transmitter circuit that modulates the output of this key code generating circuit and radiates it into the air as an electromagnetic wave. ing. Further, the electromagnetic waves emitted from the musical tone control information generating section 38 are received by a stationary musical tone generating section 41 shown in the figure. The musical tone generating section 4N includes a receiver circuit that demodulates the key code from the received electromagnetic waves, a musical tone signal generating circuit that converts the demodulated key code into a musical tone signal, and a speaker. For reference, FIG. 16 is a block diagram showing the electrical configuration of the belt-shaped musical tone control information generating section 38.
FIG. 17 is a perspective view showing the external configuration of the control information generating section 38. Since the above-mentioned musical tone control device is of a belt type worn around the waist, it has the advantage that there is less discomfort when worn.
