Description

Controller structure

The present invention relates to a manipulator structure having a plurality of wheels that are rotationally operated.

2. Description of the Related Art Conventionally, there is known an operator structure provided with a rotary operator that controls the effect of a sound to be produced (Patent Document 1). The manipulator unit provided in the device of Patent Document 1 has a detection unit having a variable resistance and the like, and the wheel is fixed to a shaft extending from the detection unit. The shaft portion rotates in conjunction with the rotation operation of the wheel, and the detection portion detects rotational displacement (operation amount) of the shaft portion. And the detection result by a detection part is used for effect control etc.

By the way, in a keyboard instrument or the like, in order to make it possible to control a plurality of effects, a plurality of operator units may be disposed corresponding to the effects to be controlled. For example, manipulator units for pitch bend and modulation are arranged adjacent to each other. The wheels of these two manipulator units are preferably located at a certain position close to each other in order to facilitate the same manual operation.

By the way, in the keyboard instrument, the wheel is usually disposed exposed on the panel surface. On the other hand, the detection unit is disposed on the substrate inside the housing. The substrate may be provided with a relief hole for preventing interference when the wheel is rotationally displaced. FIG. 5 is a view showing an arrangement example in which two manipulator units are disposed on a common substrate. The manipulator units UT1 and UT2 have the same configuration, and will be mainly described with respect to the manipulator unit UT1.

The detection unit 11 of the operator unit UT 1 is fixed to the substrate 10, and the shaft 12 extends from the detection unit 11. A wheel (not shown) is attached and fixed to the shaft 12 from the tip end side of the shaft 12. When attaching the wheel to the shaft 12, if there is a portion on the wheel that interferes with the substrate 10, a relief hole is also needed to avoid interference at the time of attachment. In the example of FIG. 5, the through hole 14 is formed in the substrate 10 corresponding to the manipulator unit UT1. The through hole 14 is a hole in which a clearance hole (region R1) for rotational displacement of the wheel and a clearance hole (region R3-1) for mounting are integrated. Similarly, the manipulator unit UT2 has a detection unit 21 and a shaft portion 22, and a through hole 24 in which the regions R2 and R3-2 are integrated is formed in the substrate 10.

Unexamined-Japanese-Patent No. 5-100673

However, as in the arrangement illustrated in FIG. 5, if the through holes are formed after securing the area to which the detection unit is attached corresponding to each of the two units, it can not be effectively used for mounting of parts, etc. There is a useless area that is difficult or difficult to use. Then, the dead space on the substrate substantially increases. For example, in the example of FIG. 5, since the region Rx is located between the two through holes 14 and 24, wiring is not easy and large parts can not be arranged. If the combined area of the through holes 14 and 24 is large, the component mounting area is reduced. Moreover, since it is necessary to secure an area for arranging one detection unit (detection unit 21) between the two wheels, it is difficult to arrange the two wheels close to each other.

An object of the present invention is to provide a manipulator structure capable of reducing a useless opening area of a substrate and facilitating the arrangement of a pair of wheels close to each other.

In order to achieve the above object, according to the present invention, a substrate (10) having an opening (H), a first detection unit (11) disposed in the vicinity of the opening in the substrate, and It has a first shaft (12) extending in a cantilever state from the first detection unit to the side of the opening hole, and the rotational displacement of the first shaft is determined by the first detection unit. A first unit (UT1) to be detected, a second detection unit disposed in the vicinity of the opening in the substrate and at a position different from the first detection unit, and the first axis A second shaft extending in a cantilevered manner from the second detection unit to the side of the opening hole so as to face the unit, and the rotational displacement of the second shaft is the second detection A second unit detected by the second unit, and a tip of the first shaft and a tip of the second shaft in the opening hole A first wheel (13) attachable to the first shaft portion from the tip end side of the first shaft portion as a relief hole (H3) and a region corresponding to the first wheel portion; An area overlapping the area used as a relief hole when mounted on the first shaft portion is used as a relief hole, and can be mounted on the second shaft portion from the tip end side of the second shaft portion And a second wheel. In addition, the code in the said parenthesis is an illustration.

According to the present invention, it is possible to reduce the useless opening area of the substrate and to easily arrange the pair of wheels close to each other.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic view of an electronic musical instrument to which a manipulator structure according to an embodiment of the present invention is applied. This operator structure is included in the electronic musical instrument 100 which is a keyboard instrument as an example. The electronic musical instrument 100 has a main body 30 and a neck 31. The main body portion 30 has a first surface 30a, a second surface (not shown), a third surface 30c, and a fourth surface 30d. The first surface 30a is a keyboard mounting surface (surface) on which the keyboard section KB including a plurality of keys is disposed. The second surface is the back surface (bottom surface), and the hooks 36 and 37 are provided on the second surface. A strap (not shown) can be placed between the hooks 36 and 37, and the player usually puts the strap on his shoulder and performs performance such as operating the keyboard KB. Therefore, at the time of use with shoulders, particularly when the scale direction (key arrangement direction) of the keyboard KB is in the left-right direction, the first surface 30a and the keyboard KB face the listener side, the third surface 30c, the fourth The faces 30d face generally downward and upward, respectively.

The neck portion 31 is provided with various operators including the advance operator 34 and the return operator 35. A display unit 33 composed of liquid crystal or the like is disposed on the fourth surface 30 d of the main body 30. A rotation knob 38 is disposed on the first surface 30a as a rotary operator, and a slide operator 39 is further disposed. The manipulator units UT1 and UT2 (first and second units) are disposed on the upper surface of the neck case 32 constituting the neck portion 31 and on the surface connected to the first surface 30a of the main body portion 30. Ru. The manipulator units UT1 and UT2 respectively have wheels 13 and 23 (first and second wheels) that are rotationally operated, and the wheels 13 and 23 are disposed adjacently and closely. The manipulator units UT1 and UT2 are units for controlling an effect to be given to a sound to be produced. The types of effects controlled by the manipulator units UT1 and UT2 are different from each other. For example, the effects of modulation and pitch bend are controlled by the manipulator units UT1 and UT2, respectively.

The electronic musical instrument 100 can simulate singing according to the control of the control unit (not shown) as well as pronouncing normal musical instrument sounds in response to the operation on the performance operators. Here, the song simulation is to output a voice simulating a human voice by song synthesis. White keys and black keys are arranged in the order of pitches of the keys of the keyboard section KB, and the keys are associated with different pitches. When playing the electronic musical instrument 100, the user presses a desired key on the keyboard KB. The electronic musical instrument 100 detects a key operated by the user, and produces a singing sound of a pitch corresponding to the operated key. The order of the syllables of the singing voice to be pronounced is predetermined.

In the present embodiment, the keyboard KB, the advance operator 34, and the return operator 35 are mainly included in the performance operators that receive the performance operation for specifying the pitch. As an example, the performance operator outputs performance information such as note-on / note-off based on sensor on / off corresponding to each key, and the strength (speed, velocity) of key depression. This performance information may be in the form of a MIDI (musical instrument digital interface) message. The manipulator units UT1 and UT2 and the rotation knob 38 are included in the parameter value setting manipulator. Although not shown, when the vocal sound is to be produced, the sound source reads voice segment data to generate singing voice data, and the effect circuit operates the parameter value setting operator with respect to the singing voice data generated by the sound source. Apply the specified sound effect. The sound system converts the singing voice data processed by the effect circuit into an analog signal, amplifies the converted singing voice, and outputs the amplified singing voice from a speaker or the like.

FIG. 2 is a plan view of a portion of the substrate. Inside the neck case 32, a substrate 10 which is a circuit board is disposed substantially horizontally. Various electronic components for realizing sound generation are mounted on the substrate 10, and the manipulator units UT 1 and UT 2 are also disposed on the substrate 10.

First, in the substrate 10, through holes H which are opening holes are formed corresponding to the pair of manipulator units UT1 and UT2. The detection unit 11 (first detection unit) of the manipulator unit UT 1 is fixed to the substrate 10. A shaft 12 (first shaft) is cantilevered from the detection unit 11 to the side of the through hole H. The detection unit 21 (second detection unit) of the manipulator unit UT 2 is fixed to the substrate 10. A shaft 22 (second shaft) is cantilevered from the detection unit 21 toward the through hole H. The shaft portion 22 is extended so as to face the shaft portion 12. The axial center C1 of the shaft 12 and the axial center C2 of the shaft 22 substantially coincide with each other.

The wheel 13 is attached and fixed to the shaft 12 from the tip end side of the shaft 12. The wheel 23 is attached and fixed to the shaft 22 from the tip end side of the shaft 22. The wheels 13, 23 are exposed on the top surface of the neck housing 32 so that part of them can be operated (FIG. 1). The manipulator units UT1 and UT2 have the same configuration including the shape as each other, but the orientations of the shaft portions are different as described above. The wheel 13 will be described representatively for the detailed configuration of the wheels 13 and 23. In the description of the configuration of the manipulator units UT1 and UT2, for convenience, the side on which the wheels 13 and 23 are exposed is referred to as the upper side.

FIG. 3A is a view of the wheel 13 on the side facing the shaft 12 when the wheel 13 is inserted into the shaft 12 (a view from the left side of FIG. 1). FIG. 3B is a side view of the wheel 13 (viewed from the lower side of the drawing of FIG. 1). The wheel 13 has the operated portion 15 in a semicircle or more area on the outer peripheral side, and has the locking piece 16 in a partial area other than the operated portion 15. The shaft 12 is inserted into the insertion hole 19 of the wheel 13. A spring 17 is attached to the wheel 13 as a biasing member. The spring 17 has two legs 17a.

FIG. 4 is a plan view of the substrate 10 near the through hole H. As shown in FIG. The locking pieces 18 are extended corresponding to the locking pieces 16 from positions near the through holes H in the substrate 10 and to which the detection units 11 and 21 are attached. 3A and 3B show the free state (initial position) in which the wheel 13 is attached to the shaft 12 and not operated. In a state where the wheel 13 is mounted on the shaft portion 12, the initial position of the wheel 13 is obtained by engaging the locking piece 16 and the locking piece 18 so as to sandwich the two leg portions 17 a of the spring 17. It is prescribed. In the initial position, the locking piece 18 is positioned above the locking piece 16, and the locking pieces 16, 18 are positioned between the two legs 17a. In the initial position, the insertion hole 19 is positioned on the upper surface 10 a side (first surface side) of the substrate 10, and the locking piece 16 is positioned on the lower surface 10 b side (second surface side) of the substrate 10. When the wheel 13 is rotated from the initial position, the leg 17a in the rotational direction is driven by the locking piece 16 while the other leg 17a is in contact with the locking piece 18 to restrict displacement. , The two legs 17a are spaced apart, whereby the wheel 13 is biased towards the initial position. Therefore, when releasing the operating hand, the wheel 13 naturally returns to the initial position.

The rotation of the shaft 12 is restricted with respect to the insertion hole 19, and when the wheel 13 rotates, the shaft 12 rotates integrally. The rotational displacement of the shaft 12 is detected by the detector 11. By the way, the detection unit 11 has a known configuration using, for example, a variable resistor or the like, and outputs an output signal according to the amount of rotation. Based on this output signal, a control unit (not shown) controls an effect corresponding to the manipulator unit UT1 on the sound to be produced. The detection part 11 just detects the rotational displacement of the axial part 12, and there is no limitation in the structure. The relationship between the wheel 23, the shaft 22, and the detector 21 is the same as the relationship between the wheel 13, the shaft 12, and the detector 11. Therefore, based on the detection signal of the rotation operation of the wheel 23, the control unit controls the effect corresponding to the manipulator unit UT2 on the sound to be produced.

The through hole H is an opening in which the clearance holes H1 and H2 for rotational displacement of the wheels 13 and 23 and the clearance hole H3 for avoiding interference at the time of attachment to the shaft portions 12 and 22 are integrated. The relief hole H3 is a region of the through hole H corresponding to the tip of the shaft 12 and the tip of the shaft 22. First, in the process of mounting the wheel 13 on the shaft portion 12, the worker places the locking piece 16 under the locking piece 18 so that the locking piece 18 is positioned between the insertion hole 19 and the locking piece 16. The shaft portion 12 is inserted into the insertion hole 19 while being positioned. FIG. 4 shows the positions of the wheel 13-A before mounting and the wheel 13-B after mounting. The operator once locates the locking piece 16 of the wheel 13 below the clearance hole H3 in the through hole H and then moves the wheel 13 to the left in FIG. Fit in Thus, when the wheel 13 is attached to the shaft portion 12, a relief hole H3 for avoiding interference is required. When the wheel 13 is rotated, the operated portion 15 may be displaced below the through hole H by the rotation. Therefore, also at the time of the rotation operation of the wheel 13, the relief hole H1 is required as a relief hole for avoiding the interference with the wheel 13. Similarly to the wheel 13, the wheel 23 can be considered to be symmetrical in FIG. Therefore, when the wheel 23 is attached to the shaft portion 22, an escape hole H3 is required to avoid interference. In addition, also at the time of the rotation operation of the wheel 23, the relief hole H2 is required as a relief hole for avoiding the interference with the wheel 23.

Here, the relief hole H3 is used when any of the wheels 13, 23 is attached. That is, at least a part of the area used as a relief hole when the wheel 13 is mounted on the shaft 12 and the area used as a relief hole when the wheel 23 is mounted on the shaft 22 overlap ing. As a result, it is not necessary to make the through holes H of the substrate 10 excessively, and the useless opening area can be reduced. If, as shown in FIG. 5, the through holes 14 and 24 are provided for each operator unit UT, two areas R3-1 and R3-2 are required as relief holes for wheel attachment. . On the other hand, in the present embodiment, the through hole H is single, and the relief hole H3 corresponds to the common use of the regions R3-1 and R3-2, compared with the example of FIG. The opening area corresponding to one region R3-2 is not wasted. Moreover, the substantial dead space such as the area Rx can be reduced.

Further, in the arrangement configuration shown in FIG. 5, since the detection unit 21 is disposed between the two wheels, it becomes difficult to bring the two wheels close to each other. On the other hand, in the present embodiment, since the shaft portion 12 and the shaft portion 22 are extended to face each other, it is easy to reduce the distance between the wheels 13 and 23 mounted on the shaft portions 12 and 22. .

According to the present embodiment, a single through hole H is provided in the substrate 10 in common to the pair of wheels 13 and 23, and in the through holes H, the relief holes H 3 have the wheels 13 and 23 as the shaft 12, Used when attaching to 22. Thereby, the useless opening area of the substrate 10 can be reduced, and the pair of wheels 13 and 23 can be easily arranged close to each other. In particular, as in the case where the present invention is applied to a small-sized musical instrument, it is suitable when space saving is highly required. Further, since the axial center C1 of the shaft portion 12 and the axial center C2 of the shaft portion 22 substantially coincide with each other, a direction orthogonal to the axial centers C1 and C2 of the through hole H (a width direction and parallel to the longitudinal direction of the key Direction) can be shortened, leading to a reduction in the useless opening area.

Moreover, since the wheels 13 and 23 have the same shape, they contribute to the reduction of the number of parts. By the way, although each of the wheels 13 and 23 has a configuration in which the spring 17 is attached and automatically returns to the initial position, the wheels 13 and 23 may not have the initial position. The locking piece 16 may be eliminated in the case of a wheel configured not to have an initial position.

Note that there may be a plurality of pairs of manipulator units, and one through hole H is formed corresponding to the pair of manipulator units.

In the present embodiment, the effect given to the singing sound is kept in mind, but the present invention is not limited to this, and the effect control of the sound generated by the performance operation in the musical instrument or the sequence data in the sound generating device The present invention is also applicable to the control of the effect of the generated sound. The parameters controlled by the wheel are not limited to modulation and pitch bend, but may be expressions or the like.

It is not essential that the controller unit is a unit that controls the effect. The controller unit may be used for an operation of changing (jumping) the reading position of the musical composition or changing the musical composition to the preceding or succeeding musical composition. For example, the controller unit may be a unit capable of stepping on or off the playing position or the selected song according to the rotational operation direction of the wheel.

The manipulator structure of the present invention may be applied to an independent effect control device that can be connected to output control information regarding an effect to an electronic musical instrument or a sound producing device. The instruments to which the present invention is applied include not only keyboard instruments but also instruments in which strings are arranged side by side like a guitar.

Although the present invention has been described in detail based on its preferred embodiments, the present invention is not limited to these specific embodiments, and various embodiments within the scope of the present invention are also included in the present invention. included.
