(First embodiment)
FIG. 1 is a block diagram showing the overall configuration of the electronic musical instrument system according to the first embodiment of the present invention. FIG. 2 is a side view of the electronic musical instrument system. As shown in FIG. 2, the electronic musical instrument system includes a keyboard musical instrument body 40 and a chair body 30 that are communicably connected via a communication line 34. As will be described in detail later, the instrument main body 40 is provided with a vibration unit 46, and the chair body 30 is provided with vibration units 31 and 32 (see FIGS. 1 and 2). The communication line 34 is a composite connection line capable of exchanging various data and signals. For example, PWM for vibrating the vibration units 31 and 32 from the instrument body 40 to the chair body 30 through the communication line 34. A drive signal which is a (Pulse Width Modulation) signal is transmitted.

  As shown in FIG. 1, the keyboard instrument body 40 includes a keyboard unit KB1, a setting operator 2, a ROM 6, a RAM 7, a timer 8, a display device 9, an external storage device 4, a MIDI interface (MIDII / F) 17, a sound source 15, A first drive control unit 37 and a second drive control unit 38 are connected to the CPU 5 via the bus 16.

  A timer 8 is connected to the CPU 5, and an external MIDI device 18 is connected to the MID II / F 17. The sound system 3 is connected to the sound source 15. The keyboard unit KB1 includes a plurality of white keys 55 and black keys 56, respectively, and further includes a key pressing switch 12 corresponding to each of the keys 55 and 56. The keyboard unit KB1 also includes a vibrating unit 46 (see also FIG. 2). The setting operator 2 includes various switches (not shown), and signals generated by these operations are supplied to the CPU 5. The key pressing switch 12 detects the key pressing operation of the corresponding keys 55 and 56, and the detection signal is supplied to the CPU 5.

  The CPU 5 controls the entire keyboard instrument body 40. The ROM 6 stores a control program executed by the CPU 5, various table data, and the like. The RAM 7 temporarily stores various input information such as performance data and text data, various flags, buffer data, calculation results, and the like. The timer 8 measures various times such as an interrupt time in the timer interrupt process. The external storage device 4 stores various application programs including the control program, various music data, various data, and the like.

  The MID II / F 17 inputs a MIDI (Musical Instrument Digital Interface) signal from the external MIDI device 18 or outputs a MIDI signal to an external device. The sound source 15 converts performance data input from the keyboard unit KB1 and performance data set in advance for reproduction into musical tone signals, and the sound system 3 converts those musical tone signals into sound. The vibration unit 46 is electrically connected to the first drive control unit 37. The vibration units 31 and 32 are both electrically connected to the first drive control unit 37 and the second drive control unit 38.

  As shown in FIG. 2, the vibration unit 46 is fixedly disposed on the shelf board 36. On the other hand, the keyboard part KB1 is also fixedly arranged on the shelf board 36, and the vibration of the vibration part 46 is transmitted to the keys 55 and 56. One vibrating portion 46 is provided over the entire key width, but a plurality of vibrating portions 46 may be provided and arranged in a plurality of locations along a key arrangement direction or the like. The vibration part 31 is fixed below the seat part 35 of the chair body 30, and vibration is transmitted to the player sitting on the seat part 35. The vibration part 32 is disposed in the backrest part 33, and when the player sitting on the chair body 30 is in contact with the backrest part 33, the vibration of the vibration part 32 is transmitted to the player through the backrest part 33. It has become.

  The vibration units 31, 32, and 46 are constituted by, for example, transducers. However, any configuration that generates vibration by a drive signal may be used, and a configuration using a motor and a vibrator, a configuration using a conductive polymer (artificial muscle), or the like may be used.

  Here, in this embodiment, in the performance guide mode, performance guide is possible according to performance data for performance guide (hereinafter referred to as “guide performance data”) which is sequence data composed of a plurality of event data. It is. That is, in accordance with the guide performance data, a musical tone is generated and a score is displayed on the display device 9. In parallel with this, the suitability of the performance by the player is monitored, and if there is a performance error, a notification vibration process (FIG. 2 described later) is performed. In step S108). In the present embodiment, as an example, this notification is made by vibrating all of the vibration units 31, 32, and 46 in a predetermined manner. For example, what is stored in the external storage device 4 is temporarily stored in the RAM 7 as guide performance data, and event data in the guide performance data is sequentially read from the RAM 7 during performance guide.

  The first mode and the second mode can be set as vibration modes in the notification vibration processing. That is, the vibration modes of the vibration units 31, 32, and 46 are varied according to the content of the performance error. There are various ways to form the embodiment, and the embodiment is not limited to any one. For example, the vibration magnitude (amplitude), speed (cycle), vibration direction (up / down, left / right, front / rear, etc.) and the like are made different in the first and second modes. The vibration in the notification vibration process is finished in a certain time. Alternatively, the vibration may be canceled in response to note-off (in the guide performance data) of the musical sound corresponding to the performance mistake.

  Note that at the time of performance guide, it is only necessary to accept the performance on the keyboard KB1 while notifying the player of the progress of the performance by any method, and generation of musical sounds based on the guide performance data and display of the score are not essential. For example, the rhythm may be notified by touch only by a metronome sound or by vibration by any of the vibration units 31, 32, and 46 instead of the metronome sound. Alternatively, each key may be provided with a light emitting function, and the progress of the performance may be notified by a so-called optical key guide function.

  Further, in the present embodiment, by setting the “acoustic assist mode” with the setting operation element 2, vibrations are generated in the vibration units 31 and 32 of the chair body 30 to play the role of acoustic assist. it can. In this case, the vibration units 31 and 32 generate vibrations according to data of a predetermined part of performance data (including performance data for guide) set for automatic performance. At that time, it vibrates with a strength corresponding to the velocity of the note-on event data of the predetermined part. The setting operator 2 can be used to set which part is the predetermined part and which one or both of the vibration units 31 and 32 are vibrated. Further, depending on the setting, the vibration units 31 and 32 can be vibrated according to the performance operation by the player, and can be vibrated according to both the performance data and the performance operation by the player. .

  In the notification vibration process, the CPU 5 sends a drive instruction signal according to the content of the performance error to the first drive control unit 37, and the first drive control unit 37 as a drive signal according to the received drive instruction signal, The PWM signal is sent to at least one of the vibration units 31, 32, and 46 according to the setting. On the other hand, in the acoustic assistance mode, the CPU 5 sends a drive instruction signal corresponding to the performance data and / or a performance operation by the player to the second drive control unit 38, and the second drive control unit 38 uses the received drive instruction signal as the received drive instruction signal. As a corresponding drive signal, a PWM signal is sent to at least one of the vibration units 31 and 32 according to the setting.

  FIG. 3 shows a flowchart of the main routine in the present embodiment. This process is started when the keyboard instrument body 40 is turned on.

  First, initialization is executed, that is, execution of a predetermined program is started, initial values are set in various registers, and initial setting is performed (step S101). Next, panel processing is executed, that is, the operation of the setting operator 2 is accepted, and device settings such as mode setting and performance setting, instructions, and the like are executed (step S102).

  In this step S102, various settings are made by the user using the setting operation element 2. For example, in the setting / non-setting of the acoustic assistance mode and the acoustic assistance mode, the vibration parts 31, 32 of the chair body 30 are actually vibrated. Things are set up. The contents of the first and second modes in the notification vibration process are also set. In addition, in the sound assistance mode, a setting is made to vibrate the vibration units 31 and 32 according to performance data or performance operation by the player (or both).

  Next, a musical tone process, that is, a performance signal is generated in accordance with performance data set to perform automatically or a detection signal of the key press switch 12, and a sound generation mute process is executed (step S103).

  Next, it is determined whether or not the acoustic assistance mode is set (step S104). And only when the acoustic assistance mode is set, the vibration unit 31, 32 in the chair body 30 that is set to actually vibrate (one or both) is determined by the performance data and / or the player. Vibrate according to the performance operation (step S105). Next, in step S106, it is determined whether or not the performance guide mode is set. If the performance guide mode is not set, the process proceeds to step S109. The performance data is compared with the actual performance (actual performance) by the performer (step S107).

  In step S107, the match between event data (event data indicated by a read pointer (not shown) for reproduction) of a predetermined part in the guide performance data and event data generated by the actual performance is determined in units of events. Compared. Specifically, in the present embodiment, a key to be depressed (key depression key) and a key depression timing are adopted as elements relating to the performance to be determined as to whether or not performance is appropriate, and these are compared and determined. With respect to the key pressing timing, it is determined that the key is pressed at the correct key pressing timing if the correct key is pressed within a predetermined time allowable range.

  As a result of the comparison, if the actual performance does not coincide with the guide performance data at either the key to be depressed or the key depression timing, a notification vibration process shown in FIG. (Step S108), the process proceeds to Step S109. Note that matching / mismatching of keys to be pressed is preferentially determined, and determination of matching / mismatching of key pressing timing is based on the premise that the keys to be pressed match. On the other hand, if both the key to be pressed and the key pressing timing match, that is, if it is determined that the correct performance has been made, the process proceeds to step S109 without executing the notification vibration process. In step S109, other processing is executed, and the process returns to step S102.

  FIG. 4A is a flowchart of the notification vibration process executed in step S108 of FIG. 3 in the present embodiment.

  First, as a result of the comparison in step S107 in FIG. 3, it is determined whether or not the content of mismatch is a key to be pressed or a key pressing timing (step S201). If the keys to be pressed do not match, the vibration processing is performed in the set first mode (step S202). If the key pressing timings do not match, the set second mode is set. Vibration processing is performed in the mode (step S203). Thereafter, this process is terminated.

  According to the present embodiment, when the performance guide is executed, the performance data for guide is compared with the actual performance by the performer, and if there is a performance error, the vibration units 31, 32, and 46 are vibrated. These vibrations are transmitted to the hand which is a performance limb through the keyboard instrument body 40 and also transmitted to the body through the chair body 30. Therefore, whether or not the performance is appropriate can be recognized by tactile sense. That is, since it is a tactile recognition mechanism rather than a visual recognition mechanism, it is not always necessary to stare at the keyboard, it is easy to practice performance while looking at the score, and the movement of the line of sight is small.

  Also, since the vibration mode in the notification vibration process is changed according to the content of the mismatch, the content of the performance operation in which there was an error, specifically, whether the operated key is incorrect or the key pressing timing is incorrect Can be recognized by the mode of vibration of the vibration units 31, 32, 46.

  Further, in the acoustic assistance mode, the vibration unit 31 or the vibration unit 32 of the chair body 30 is controlled to vibrate for acoustic assistance in accordance with the reading of performance data or a performance operation by the player, so only the sound by the sound system 3 is controlled. In addition, automatic performance or actual performance can be sensed by touch, and sound can be felt from various angles. In addition, the vibration units 31 and 32 are used not only for acoustic assistance but also in the notification vibration process as described above. That is, since the vibration units 31 and 32 are used for both sound assistance and misperformance notification, it is not necessary to provide a dedicated vibration mechanism for sound assistance, and it is easy to recognize whether or not the performance is appropriate by tactile sense. Can be configured as much as possible.

  In addition, although what was vibrated in alerting | reporting vibration processing was made into all the vibration parts 31, 32, and 46, it is not restricted to this. For example, at least one of these may be used, and what is actually vibrated may be set by the user in step S102 of FIG.

(Second Embodiment)
The second embodiment of the present invention differs from the first embodiment only in the notification vibration process, and the other configurations and processes are the same. Therefore, this embodiment will be described with reference to FIG. 4B instead of FIG. In the first embodiment, the vibration mode is made different depending on the content of the mismatch, but in the present embodiment, the vibration part that is actually vibrated is made different depending on the content of the mismatch.

  FIG. 4B is a flowchart of the notification vibration process executed in step S108 of FIG. 3 in the second embodiment of the present invention.

  First, in step S301, processing similar to that in step S201 in FIG. If the key to be pressed does not match, the set first assigned vibration unit is vibrated (step S302), while if the key pressing timing does not match, the set second assigned vibration unit is vibrated. The allocated vibration unit is vibrated (step S303). Thereafter, this process is terminated.

  Here, the allocation to the first and second allocation vibration units is performed by the user in step S102 of FIG. As an example, the vibration part 46 of the musical instrument main body 40 is assigned to the first assigned vibration part, and the vibration parts 31 and 32 of the chair body 30 are assigned to the second assigned vibration part. Note that the vibration unit assigned (selected) as the first and second assigned vibration units may be at least one of the vibration units 46, 31, and 32, and between the first and second assigned vibration units. There may be a vibrating section that is assigned to the same.

  According to the present embodiment, in the notification vibration process, the vibration part to be actually vibrated can be selected according to the contents of the mismatch, so that the performance operation content with the error is the error of the operated key or the pressed key. Whether the key timing is wrong can be recognized depending on which vibration part vibrates.

  In the notification vibration process, the process of changing the vibration mode in the first embodiment may be combined with the process of selectively vibrating the vibration unit in the second embodiment. That is, according to the content of mismatch, both the vibration part to vibrate and the mode of the vibration may be varied.

(Third embodiment)
In the first embodiment, one type of vibration unit 46 in the keyboard instrument body 40 is fixed on the shelf board 36. On the other hand, in the third embodiment of the present invention, two types of vibration units are provided in place of the vibration unit 46, and one of them is arranged so that vibration is efficiently transmitted to the key when the key is pressed. The

  FIG. 5 is a right side view of the front half portion of the keyboard musical instrument body seen through in the electronic musical instrument system according to the third embodiment of the present invention. FIG. 6 is a plan view of the keyboard part KB2.

  It is assumed that the keyboard instrument body 60 is communicably connected to the same chair body 30 as in the first embodiment via the communication line 34. The keyboard instrument body 60 is held on a stand (not shown). The configuration and control contents of the control mechanism of the keyboard instrument main body 60 are the same as those in the first embodiment (see FIGS. 1, 3, and 4A).

  As shown in FIG. 5, the keyboard instrument main body 60 is configured such that a keyboard portion KB <b> 2 is accommodated in a case body 49. The case body 49 is formed by joining and fixing an upper case 49A and a lower case 49B. The upper frame 70 is screwed and fixed to the lower frame 50 of the lower case 49B with screws (not shown) at a plurality of locations. For example, at least a lower portion of the intermediate portion 70a that is an intermediate portion in the front-rear direction of the upper frame 70 and an intermediate portion 50a that is an intermediate portion in the front-rear direction of the lower frame 50 are fixed, and the bottom portion 70ca and the lower portion in the front portion 70c of the upper frame 70 are fixed. The front portion 50c of the frame 50 is fixed. A key unit UNT1 is attached to the upper frame 70. Hereinafter, the player side (left side in FIG. 5) of the keyboard instrument main body 60 is referred to as the front, and the left and right directions are referred to as the player.

  The key unit UNT1 is configured, for example, in units of one octave and includes a plurality of white key bodies 47 and black key bodies 48, respectively. The key bodies 47 and 48 are connected to the common base end portion 51 through the respective hinge portions 52, and can be rotated (swinged) in the vertical direction (pressing and releasing key direction) with the common base end portion 51 as a key fulcrum portion. It has become.

  As shown in FIG. 5, a lower limit stopper 11 is provided on the bottom portion 70 ca of the upper frame 70 to restrict the lower limit position (key press end position) when the key bodies 47 and 48 are pressed. In the front lower portion of the substrate support portion 70b located between the bottom portion 70ca and the intermediate portion 70a in the front-rear direction of the upper frame 70, an upper limit position (pressing key) when the key bodies 47 and 48 are not pressed. An upper limit stopper 14 for regulating the key initial position) is provided. Both the lower limit stopper 11 and the upper limit stopper 14 are made of an elastic member such as felt. The lower limit stopper 11 and the upper limit stopper 14 are provided in common to the plurality of key bodies 47 and 48, but may be provided in common to all the key bodies 47 and 48 or corresponding to the key bodies 47 and 48.

  The key pressing switch 12 is disposed on the substrate support portion 70 b of the upper frame 70 in correspondence with each of the key bodies 47 and 48. In FIG. 5, illustration of an attachment portion or a substrate for attaching the key pressing switch 12 is omitted.

  Stopper abutting pieces 29 and 30 that abut against the lower limit stopper 11 when the key is depressed are formed to hang from the front portions of the white key body 47 and the black key body 48. After the key unit UNT1 is assembled to the upper frame 70, when a key pressing operation is performed, the white key main body 47 and the black key main body 48 rotate downward (toward the key pressing direction) due to the elasticity of the hinge 52, and the lower limit. The lower end of the stopper abutting pieces 29 and 30 comes into contact with the stopper 11, and the key pressing is finished. On the other hand, when the key is released, the key bodies 47 and 48 are rotated upward (return direction of the key pressing) by the elasticity of the hinge portion 52, and the upper ends of the portions extending rearward of the stopper contact pieces 29 and 30 are It comes into contact with the upper limit stopper 14 and returns to the key pressing initial position.

  As shown in FIG. 5, below the substrate support portion 70b, a vibrating portion 53 (53A, 53B, 53C) is disposed on the upper surface of the bottom portion 50b between the intermediate portion 50a and the front portion 50c of the lower frame 50. It is fixed. In addition, a vibrating portion 54 (54A, 54B, 54C) is disposed and fixed on the lower surface of the front portion 50c of the lower frame 50. The configuration of the vibration units 53 and 54 is the same as that of the vibration units 31, 32, and 46 in the first embodiment.

  As shown in FIG. 6, the vibration units 53 and 54 are both arranged at a plurality of locations (for example, 3 locations) along the key arrangement direction. In particular, the vibration part 54 is long in the key arrangement direction and the gap between each other is small, and all the key bodies 47, 48 overlap with any of the vibration parts 54A, 54B, 54C in plan view. In addition, as shown in FIG. 5, the lower limit stopper 11 and the vibrating portion 54 are in a fixed relationship and close to each other via the front portion 50 c of the lower frame 50 and the bottom portion 70 ca of the frame 70. As a result, the vibration of the vibration portion 54 is directly and efficiently transmitted to the key bodies 47 and 48 in the key-pressing complete state directly through the stopper contact pieces 29 and 30. In addition, vibration can be efficiently transmitted to the depressed key without providing a vibration part for each key, and the configuration is simple.

  In such a configuration, the process in the acoustic assistance mode (step S105 in FIG. 3) and the notification vibration process (step S108 in FIG. 2, FIG. 4A) are the same as those in the first embodiment. Here, all of the vibration units 31, 32, 53, and 54 are vibrated in the notification vibration process. However, the present invention is not limited to this, and at least one of them may be used. For example, only the vibration parts 53 and 54 in the keyboard instrument main body 60 may be set as vibration targets. In particular, since the vibration part 54 has a high vibration transmission effect as described above, the vibration part 54 is preferably included in the vibration target.

  According to the present embodiment, the same effects as those of the first embodiment can be obtained. However, not only that, the vibrating portion 54 is disposed so as to be fixed with respect to the lower limit stopper 11, and the vibration is disposed so as to be directly transmitted to the lower limit stopper 11. Sometimes the vibration is efficiently transmitted to the finger pressing the key through the stopper abutting pieces 29 and 30, and the performance error can be recognized more clearly.

(Fourth embodiment)
In the third embodiment, when the vibration unit 54 vibrates, the vibration is efficiently transmitted to the key bodies 47 and 48 in the key pressing end state. In this embodiment, the vibration of the vibration part is efficiently transmitted to the key body in the entire process of pressing and releasing keys.

  FIG. 7 is a cross-sectional view of the front half of the keyboard instrument body in the electronic musical instrument system according to the fourth embodiment of the present invention.

  It is assumed that the keyboard instrument body 80 is communicably connected to the same chair body 30 as in the first embodiment via the communication line 34. The keyboard instrument body 80 is held on a stand (not shown). The configuration and control contents of the control mechanism of the keyboard instrument body 80 are the same as those of the first embodiment (see FIGS. 1, 3, and 4A).

  The keyboard instrument body 80 has a keyboard part KB3, and a key unit UNT2 is attached to the key frame 10. Hereinafter, the player side (left side in FIG. 7) of the keyboard instrument body 80 is referred to as the front, and the left and right directions are referred to as the player.

  Although not shown in detail, the black key unit BU includes a black key body 28 corresponding to the pitches C #, D #, F #, G #, and A #. The first white key unit WU1 includes a white key body 27 corresponding to the pitches C, E, G, and B, and the second white key unit WU2 includes a white key body corresponding to the pitches D, F, and A. 27. The upper surfaces of the front half of the white key body 27 and the black key body 28 function as key pressing surfaces 27a and 28a. The white key and black key units WU1, WU2, and BU are each formed by integral molding with resin.

  In the present embodiment, as shown in FIG. 7, the lower limit stopper 11 that regulates the lower limit position (key press end position) when the white key body 27 and the black key body 28 are depressed is the front portion 10 c of the key frame 10. Is provided at the bottom 10ca. Further, an upper limit stopper 14 that regulates an upper limit position (key press initial position) at the time of key release that is also a non-key press position of the key bodies 27 and 28 is provided on the lower surface of the front portion 10 c of the key frame 10. The key press switch 12 is disposed in the intermediate portion 10 b of the key frame 10.

  On the upper front part of the intermediate part 10b of the key frame 10, a projecting ridge part 42 protruding upward is integrally formed along the key arrangement direction. Further, an elastic material 41 is fixedly provided on the front side of the upper part of the front part of the intermediate part 10 b including the protrusion 42 corresponding to the key bodies 27 and 28. In addition, on the lower surface of the front portion of the intermediate portion 10b, a vibrating portion 45 that replaces the vibrating portion 54 (see FIGS. 5 and 6) in the third embodiment is disposed and fixed. The configuration of the vibration unit 45 is the same as that of the vibration units 31, 32, and 46 in the first embodiment.

  Stopper abutting pieces 43 and 44 are formed to hang from the front portions of the white key body 27 and the black key body 28. The stopper abutting pieces 43 and 44 have their lower portions extending forward, and the portions extending forward are inserted into the corresponding notches 10 d of the front portion 10 c of the key frame 10. The lower limit stopper 11 is disposed at a position where the stopper contact pieces 43 and 44 of the key bodies 27 and 28 that have been pressed come into contact.

  As shown in FIG. 7, in the black key unit BU, a thin plate-like hinge portion 26 extends downward from the rear end portion of each black key body 28, and the lower end portion of the hinge portion 26 has a predetermined key area (for example, It is connected to the black key common base end 23 over a length of one octave). The hinge portion 26 and the black key common base end portion 23 extend in the vertical direction and are parallel to the key arrangement direction (left-right direction). Each black key body 28 can be rotated (swinged) in the vertical direction (pressing and releasing key direction) with the black key common base end portion 23 as a key fulcrum portion via a corresponding hinge portion 26.

  Similarly to the black key unit BU, in the first white key unit WU1, the hinge portion 24 extends downward from the rear end portion of each white key body 27, and the lower end portion of the hinge portion 24 is common to the first white key. Connected to the base end 21. In the second white key unit WU2, the hinge portion 25 extends downward from the rear end portion of each white key main body 27, and the lower end portion of the hinge portion 25 is connected to the second white key common base end portion 22. Yes. Each white key body 27 is rotatable in the vertical direction via the corresponding hinge portions 24 and 25 with the first and second white key common base end portions 21 and 22 as key fulcrum portions. The hinge portion 24 and the first white key common base end portion 21, the hinge portion 25 and the second white key common base end portion 22 all extend in the vertical direction, form a right angle with the key pressing surface 27 a, and the key arrangement direction Is parallel.

  The key unit UNT2 is assembled integrally in advance and attached to the key frame 10. When the first white key unit WU1, the second white key unit WU2, and the black key unit BU are assembled, as shown in FIG. 7, the first white key common base end portion 21, which is a common base end portion, The second white key common base end portion 22 and the black key common base end portion 23 are stacked in order from the front. The common base end portions 21 to 23 are brought into contact with each other and laminated to form a laminated state in three layers.

  Concentric holes (not shown) penetrating in the front-rear direction are formed in the common base end portions 21 to 23. Through these holes, the common base end portions 21 to 23 are screwed and fixed to the rear portion 10a of the key frame 10 from behind by screws 19. Thereby, the white key body 27 and the black key body 28 are supported so as to be rotatable with respect to the key frame 10.

  After the key unit UNT2 is assembled to the key frame 10, when the key is pressed, the white key main body 27 and the black key main body 28 are rotated downward (the key pressing forward direction) by the elasticity of the hinge portions 24-26. Then, the lower end stopper 11 comes into contact with the lower ends of the stopper abutting pieces 43 and 44, and the key pressing is finished. On the other hand, when the key is released, the white key main body 27 and the black key main body 28 are rotated upward (return direction of the key press) by the elasticity of the hinge portions 24 to 26, and the front of the stopper contact pieces 43 and 44. The upper ends of the portions extending to the upper end abut against the upper limit stopper 14, and the key bodies 27 and 28 are returned to the key pressing initial position.

  By the way, the hinge portions 24, 25, 26 extend downward at positions below the key pressing surfaces 27a, 28a, and the common base end portions 21-23 are positioned below the key pressing surfaces 27a, 28a. The locus of the key pressing surfaces 27a and 28a at the time of key pressing is better than that of a configuration in which the hinge portion extends upward or a general horizontal hinge configuration. That is, usually, any position on the key pressing surfaces 27a and 28a (hereinafter referred to as “key pressing point”) is rotated and moved on a circle around the rotation fulcrum by the key pressing. When the key is pressed, the key pressing point moves backward as the key pressing proceeds.

  However, in addition, in the case of a hinge type key, the key pressing point is displaced by the bending of the hinge portion. For example, in the case of a horizontal hinge, a rearward displacement of the position of the key pressing point due to the downward deflection of the front part of the hinge part is added. Even in the configuration in which the hinge portion extends upward, the rearward displacement of the key pressing point position due to the backward deflection of the lower portion of the hinge portion is added. A smaller amount of backward displacement of the key pressing point is preferable for performance.

  However, in this embodiment, the upper portions of the hinge portions 24, 25, and 26 are bent forward by the key depression, so that the deflection of the hinge portions 24, 25, and 26 is a rotational movement around the rotation fulcrum. This will act in the direction of canceling out the backward displacement due to. Specifically, in the present embodiment, in the key pressing forward stroke, the position of the key pressing point in the front-rear direction is gradually displaced forward.

  With such a hinge configuration, the substantial key pressing point trajectory is close to the key pressing point trajectory of a key that is long like an acoustic grand piano and has a fulcrum at the bottom of the key. Therefore, it is possible to make the locus of the key pressing surfaces 27a and 28a favorable so as to be in a more preferable state for improving the expressive power.

  Here, since the upper ends of the hinge portions 24, 25, and 26 are bent in the front-rear direction, the white key main body 27 and the black key main body 28 are moved in the front-rear direction through the bending of the corresponding hinge portions 24, 25, 26. Can be displaced. Therefore, if no measures are taken, when a force is applied from the front to the key bodies 27, 28 from the front by hand or the like, the key bodies 27, 28 are easily displaced rearward, and the hinge portions 24- There is a possibility that an excessive stress is applied to 26.

  However, in the present embodiment, when a backward force is applied to the key bodies 27 and 28, the stopper abutting pieces 43 and 44 abut against the elastic member 41, and a forward force against the backward operation force. Is provided to the stopper abutting pieces 43 and 44 via the elastic member 41. Thereby, since the backward displacement of the key bodies 27 and 28 in the non-key-pressed state is suppressed, the amount of bending of the hinge portions 24 to 26 is small, and plastic deformation thereof is prevented. As described below, such an action can occur not only in the non-key-pressed state but also in the entire stroke of the key-release key.

  FIG. 8 is an enlarged view of the stopper contact pieces 43 and 44. The contact surface 41a of the elastic member 41, which is the front surface on the side in contact with the stopper contact pieces 43, 44, is formed in a curved surface having a curvature radius R1 that is convex forward in a side view. On the other hand, in the stopper abutting pieces 43, 44, the rear surfaces 43a, 44a facing the abutting surface 41a of the elastic member 41 are formed in a curved surface shape having a concave curvature radius R1 in front of the side view. The rear surfaces 43a and 44a and the contact surface 41a are close to each other with a slight gap. When the key bodies 27 and 28 are urged rearward in the non-key-pressed state, both come into surface contact.

  Further, as indicated by a two-dot chain line in FIG. 8, at least the curved surfaces of the rear surfaces 43a and 44a of the stopper abutting pieces 43 and 44, which are opposed to the abutting surface 41a, have a key body 27, The shape is such that the position in the front-rear direction does not change during the 28 rotation strokes. In other words, the distance between the rear surfaces 43a and 44a and the contact surface 41a is constant at any time during the pressing and releasing key stroke. As a result, even if the key bodies 27 and 28 are urged rearward at any time during the pressing / releasing key stroke, the rear surfaces 43a and 44a and the contact surface 41a can be connected to each other as long as the key bodies 27 and 28 are urged backward. Abut. On the other hand, when a normal key pressing operation without a backward operation is performed, the rear surfaces 43a and 44a and the contact surface 41a do not contact each other, so that the key pressing operation can be performed without any trouble. That is, in the state where the rearward urging force is not applied, the stopper contact pieces 43 and 44 and the elastic member 41 are not in contact with each other in the entire stroke of the key to be pressed, but they are close to each other with a very narrow interval. Yes.

  Here, although not shown in detail, the vibration part 45 is disposed at a plurality of places (for example, three places) with a small gap along the key arrangement direction in the same manner as the vibration part 54. All the key bodies 27 and 28 overlap with any one of the vibrating portions 45 in plan view. Moreover, as shown in FIG. 7, the elastic member 41 and the vibrating portion 45 are in a fixed relationship and close to each other via the upper front portion of the intermediate portion 10 b. In addition, it is assumed that the vibration unit 45 vibrates largely in the front-rear direction. Accordingly, when the vibration portion 45 vibrates, the elastic material 41 also vibrates due to the vibration, and the elastic material 41 repeats contact / separation with the stopper contact pieces 43 and 44 in small increments. As a result, the vibration of the vibrating portion 45 is transmitted to the key bodies 27 and 28 through the stopper abutting pieces 43 and 44 in the entire process of pressing and releasing keys.

  In such a configuration, the process in the acoustic assistance mode (step S105 in FIG. 3) and the notification vibration process (step S108 in FIG. 2, FIG. 4A) are the same as those in the first embodiment. Here, all of the vibration units 31, 32, and 45 are vibrated in the notification vibration process. However, the present invention is not limited to this, and at least one of them may be used. For example, only the vibration unit 45 in the keyboard instrument body 80 may be a vibration target. In particular, since the vibration part 45 has a high vibration transmission effect as described above, the vibration part 45 is preferably included in the vibration target.

  According to the present embodiment, vibration is efficiently transmitted to the key-pressing finger, so that the same effect as that of the third embodiment can be achieved with respect to making the performance error clearly recognized. However, not only that, but the vibration of the vibration part 45 is transmitted to the key bodies 27 and 28 in the entire process of pressing and releasing keys, so that it is possible to clearly recognize a performance error even in the initial key pressing or in the middle of key pressing. .

  Further, according to the present embodiment, since the vibration part 45 mainly vibrates in the front-rear direction, the key depression switch 12 can accurately make up and prevent chattering when the key is depressed.

  In addition, the elastic member 41 functions as a stopper for suppressing excessive displacement of the key bodies 27 and 28 to the rear, and also functions to transmit the vibration of the vibration part 45 to the key bodies 27 and 28. There is no unnecessarily complicated.

  In the third and fourth embodiments, the notification vibration process is performed by applying the process of FIG. 4B instead of FIG. 4A, as in the second embodiment. Also good. In this case, at least one of the vibration units 31, 32, 53, and 54 in the third embodiment is assigned (selected) as the first and second allocation vibration units, and the fourth embodiment In the form, at least one of the vibration units 31, 32, and 45 may be used, and there may be a vibration unit that is allocated in an overlapping manner between the first and second allocation vibration units.

  From the viewpoint of simplifying the configuration, in the third embodiment, the lower limit stopper 11 and the vibrating portion 54 may be configured integrally, and in the fourth embodiment, the elastic material 41 and You may comprise the vibration part 45 integrally.

  In each of the above embodiments, the elements relating to the performance to be determined as to whether or not the performance is appropriate are not limited to the key to be pressed and the key pressing timing. For example, the key pressing length (sound length) (or key release timing) or the like may be used as the determination factor of the matching state. In the notification vibration process (see FIG. 4A), three or more vibration modes may be provided according to the number of element types. Alternatively, in the notification vibration process (see FIG. 4B), the number of vibration unit allocation patterns may be three or more.

  In each of the above embodiments, the vibration unit to be disposed may be disposed in the keyboard instrument main body 40, 60, 70 so that vibration is transmitted to the key main body. Therefore, it may be provided in common for a plurality of operators, or may be provided for each operator. What is necessary is just to arrange | position about the vibration part provided in the chair body 30 so that it may be transmitted to the body of the player who is sitting.

  In addition, although the keyboard musical instrument was illustrated as a musical instrument which comprises an electronic musical instrument system, it is not restricted to this. That is, when a vibration unit is provided in the musical instrument main body, the vibration may be transmitted to a limb to be played or a body part in contact with the limb. The performance operator is not limited to a key operated with a finger, and may be a pedal, a foot key, or the like.

  It should be noted that the present invention can also be applied to an electronic musical instrument system including a keyboard instrument with a hammer body in which a hammer body that imparts appropriate inertia to a key depression is rotated in conjunction with the key. .
