It is configured as follows.

  Thereby, as shown in FIG. 5 and FIG. 7B, the second restricting portion 21 separates the spring operating portion 19 from between the pair of spring legs 17 a and 17 b of the spring member 8, and the spring operating portion 19. The position of the switching member 9 is restricted while the engagement of the spring member 8 is released.

Next, the operation of the electronic keyboard instrument switch device 5 will be described.
When the switch device 5 is used by switching to the pitch bend function, first, the switching member 9 is pushed into the instrument main body 1 as shown in FIG. At this time, when the operation head portion 18 a of the operation lever portion 18 of the switching member 9 is pushed into the instrument main body 1, the spring operation portion 19 of the switching member 9 is provided in the extending portion 14 of the rotation operation member 7. It slides in the slide hole 14 a and is inserted between the pair of spring legs 17 a and 17 b of the spring member 8.

  Then, the position of the switching member 9 is regulated by the first regulating unit 21. At this time, when the first protrusion 21a of the first restricting portion 21 gets over the locking protrusion 23 provided in the slide hole 14a of the extending portion 14 of the rotation operation member 7, the operation head of the operation lever portion 18 is moved. The portion 18a contacts the outer surface of the instrument body 1.

  As described above, when the operation head 18a of the operation lever portion 18 contacts the outer surface of the musical instrument main body 1, the extension portion of the rotation operation member 7 is configured such that the first protrusion 21a of the first restriction portion 21 is pulled back. 14 is pressed against the locking projection 23 provided in the slide hole 14a. For this reason, the position of the switching member 9 is restricted in a state where the spring operating portion 19 is disposed between the pair of spring legs 17 a and 17 b of the spring member 8.

  Thereby, the switch apparatus 5 switches to a pitch bend function. In this state, when a part of the operation main body 13 of the rotary operation member 7 protruding from the opening 2 a provided on the upper surface of the musical instrument main body 1 and exposed to the upper side of the musical instrument main body 1 is rotated, The rotation shaft 11 of the switch unit 6 rotates with the rotation, and the switch body 10 outputs an electrical signal to the rotation shaft 11 according to the rotation.

  At this time, since the pair of spring legs 17a and 17b of the spring member 8 are in contact with both side portions of the spring contact portion 12a of the mounting member 12, the operation main body portion 13 of the rotation operation member 7 in this state is shown in FIG. When the rotation member is rotated counterclockwise, the switching member 9 is rotated in accordance with the rotation of the rotation operation member 7.

  Then, the spring operating portion 19 of the switching member 9 rotates and moves one spring leg 17a against the spring force of the spring member 8 so as to spread it in the counterclockwise direction. At this time, the spring operation portion 19 rotates and moves together with the rotation operation member 7, and the operation lever portion 18 moves counterclockwise along the semicircular arc guide hole 20 of the musical instrument main body 1. When the rotation operation of the rotation operation member 7 is released, the rotation operation member 7 returns to the original rotation position by the spring force of the spring member 8.

  Further, when the operation main body 13 of the rotation operation member 7 is rotated in the opposite direction to that described above, that is, in the clockwise direction in FIG. 3, the switching member 9 rotates and moves with the rotation of the rotation operation member 7. Nine spring operating portions 19 rotate and move the other spring leg 17b in a clockwise direction against the spring force of the spring member 8.

  Also at this time, since the pair of spring legs 17a and 17b of the spring member 8 are in contact with both side portions of the spring contact portion 12a of the mounting member 12, the spring operation portion 19 and the rotation operation member 7 are in this state. The operation lever portion 18 rotates in the clockwise direction along the semicircular arc guide hole 20 of the musical instrument main body 1. When the rotation operation of the rotation operation member 7 is released, the rotation operation member 7 returns to the original rotation position by the spring force of the spring member 8.

  On the other hand, when the switch device 5 is used by switching to the modulation function, first, the switching member 9 is pulled out toward the outside of the instrument body 1 as shown in FIG. At this time, when the operation head 18 a of the operation lever portion 18 of the switching member 9 is pulled out toward the outside of the instrument main body 1, the spring operation portion 19 of the switching member 9 is provided in the extending portion 14 of the rotation operation member 7. The inside of the slide hole 14a is slid and separated from the pair of spring legs 17a, 17b of the spring member 8.

  Then, the position of the switching member 9 is regulated by the second regulating unit 22. At this time, when the second protruding portion 22a of the second restricting portion 22 gets over the locking protruding portion 23 provided in the slide hole 14a of the rotation operating member 7, the restricting protruding portion 24 of the spring operating portion 19 is It engages with a locking recess 25 provided in the slide hole 14 a of the rotation operation member 7. For this reason, the switching member 9 is engaged with the locking projection 23 in a state where the second projection 22a has passed over the locking projection 23, and the spring operating portion 19 of the switching member 9 is detached from the spring member 8. Is restricted.

  Thereby, the switch apparatus 5 switches to a modulation function. In this state, when a part of the operation main body 13 of the rotary operation member 7 protruding above and exposed from the musical instrument main body 1 is rotated, the rotation shaft 11 of the switch unit 6 rotates as the operation main body 13 rotates. The switch body 10 outputs an electrical signal to the rotating shaft 11 according to the rotation. At this time, the pair of spring legs 17 a and 17 b of the spring member 8 are in contact with both side portions of the spring contact portion 12 a of the mounting member 12.

  For this reason, when the operation main body 13 of the rotation operation member 7 is rotated in either the counterclockwise direction or the clockwise direction in FIG. 3, the spring main body 16 of the spring member 8 is moved to the cylindrical axis of the rotation operation member 7. It idles along the outer peripheral surface of the part 15. Thereby, the rotation operation member 7 rotates without being influenced by the spring force of the spring member 8. Also at this time, the spring operating portion 19 rotates together with the rotation operating member 7 and the operating lever portion 18 moves along the semicircular arc guide hole 20 of the musical instrument main body 1.

  As described above, according to the switch device 5 of the electronic keyboard instrument, the switch unit 6 that outputs an electric signal according to the rotation of the rotary shaft 11, and the rotary shaft 11 attached to the rotary shaft 11 of the switch unit 6. A rotating operation member 7 that rotates, a spring member 8 that urges the rotation operation member 7 toward a predetermined rotation position, and a spring member 8 that engages and disengages in response to a switching operation. A switching member 9 that applies the spring force of the spring member 8 to the rotation operation member 7 and releases the spring force of the spring member 8 with respect to the rotation operation member 7 by being separated from the spring member 8 in response to the switching operation. Therefore, the pitch bend function and the modulation function, which are two functions, can be easily switched to one of them with one component member.

  That is, in this switch device 5, when the switching member 9 is detachably engaged with the spring member 8 by a switching operation, the spring force of the spring member 8 can be applied to the rotation operation member 7. Of the two functions, the modulation function, the pitch bend function, which is one function, can be surely switched, whereby the rotation operation member 7 can be operated as the pitch bend function.

  Further, in this switch device 5, when the switching member 9 is separated from the spring member 8 by the switching operation, the spring force of the spring member 8 with respect to the rotation operation member 7 can be released, so that the pitch bend function and the modulation function 2 Among the two functions, it is possible to surely switch to the modulation function, which is another function, and thereby the rotation operation member 7 can be operated as the modulation function.

  For this reason, in this switch device 5, it is possible to easily and reliably switch between the pitch bend function and the modulation function, which are two functions, with only one switching member 9 by switching the switching member 9. As a result, it is not necessary to provide the switch device 5 for each of the two functions, so that the entire device can be downsized, the number of parts can be reduced, and the cost can be reduced.

  In this case, in the switch device 5, the switch portion 6 is attached to an attachment member 12 provided in the musical instrument main body 1, and a part of the rotation operation member 7 attached to the rotary shaft 11 of the switch portion 6 is part of the musical instrument main body 1. Since the projection 2 is exposed to the outside of the musical instrument main body 1 through the opening 2 a provided in the musical instrument main body 1, even if the switch unit 6 is incorporated in the musical instrument main body 1, the rotation operation member 7 exposed to the outside of the musical instrument main body 1 is exposed.
