Description

  The present invention relates to a hi-hat type electronic pad suitable for an electronic percussion instrument.

  The acoustic hi-hat (hereinafter referred to as “HH”) cymbal not only produces a musical sound when the top cymbal is struck by a stick, but also the top cymbal moves up and down by pedal striking, that is, when the pedal is operated. Musical sound is generated by touching.

  2. Description of the Related Art Conventionally, an electronic percussion instrument that detects a pedal operation and can output a detection signal for musical tone control corresponding to the pedal operation, such as pedal hitting, is known (Patent Documents 1 to 3).

  For example, in the following Patent Document 1, a sensor for detecting the amount of pedal depression is provided on the pedal itself. There are no cymbals.

  Further, in Patent Document 2 below, a sensor is provided inside the electronic pad to be hit, and the pedal is operated to lower the movable shaft that passes through the center of the hi-hat part, which is the electronic pad, and turn on the sensor. Yes. The hi-hat part itself does not move up and down.

In Patent Document 3 below, a movable arm that moves up and down by a pedal operation is provided, and the first switch and the second switch are sequentially turned on via the movable arm when the pedal is depressed. The cymbal itself does not move up and down.
JP 2003-316355 A Japanese Utility Model Publication No. 6-11000 JP 60-217394 A

  However, none of the above Patent Documents 1 to 3 is a configuration in which the pad corresponding to the top cymbal itself moves up and down, and the appearance of the operation at the time of hitting the pedal is very different from the acoustic HH cymbal. is there. Moreover, the apparent movement of the moving object that is operated when the pedal is operated and the correspondence with the actually generated musical sound are different from those of the acoustic, and there is a sense of incongruity.

  By the way, like the acoustic HH cymbal, if the pad corresponding to the top cymbal is actually moved up and down in conjunction with the pedal operation and the movement is detected, the pedal operation can be detected realistically (near the acoustic one). There is a possibility. However, since the top cymbal is struck and swings, it does not always maintain a horizontal state when it is lowered by a pedal operation. For this reason, in order to accurately detect the vertical movement of the pad corresponding to the top cymbal, it is considered necessary to devise a technique that takes into account the occurrence of tilt due to the swing of the pad.

  The present invention has been made to solve the above-mentioned problems of the prior art, and its purpose is to enable detection of a realistic vertical movement of a movable pad body that operates in the same manner as the top cymbal of an acoustic HH. An object of the present invention is to provide a hi-hat type electronic pad that can accurately detect an operation by causing an operation sensor to be pressed by an actuator even when the movable pad body is lowered in an inclined state.

  In order to achieve the above object, the hi-hat type electronic pad according to claim 1 of the present invention is struck by swinging and moved up and down together with a support body (47) movable up and down by pedal operation.

The base portion (65) is used as a base portion (65), and the actuator (68A) projecting from the base portion in the other opposite direction in the vertical direction and the sensor laying surface (60a) facing the actuator are laid in a plane, And a motion sensor (61A) that outputs a signal due to being pressed by the actuator, the base portion being configured to be able to approach and separate from the sensor laying surface, The motion sensor is configured to output a detection signal when the motion sensor is pressed by the actuator by contacting the other, and the motion sensor is configured to have a substantially annular shape in plan view. And

  Preferably, a plurality of the motion sensors (61A to 61E) are provided concentrically at different positions in the radial direction, and the actuators (68A to 68E) are provided corresponding to each of the plurality of motion sensors. In the state where a plurality of sets of the motion sensors and the corresponding actuators are configured, and the motion detection unit and the other are not in contact with each other, the motion sensor and the actuator in the radially outer set are mutually connected. Is set to be small, and when the motion detection unit and the other are in contact with each other, detection signals are sequentially output from the outer set of motion sensors in the radial direction (Claim 2).

  Preferably, at least the innermost set of motion sensors (61E) in the radial direction is laid intermittently in the circumferential direction, and the radially outer set of motion sensors has a wider laying range in the circumferential direction and is annular. Close (Claim 3).

It exists at least in the place (claim 4).

  In addition, the code | symbol in the said parenthesis is an illustration.

  According to the first aspect of the present invention, it is possible to detect a realistic vertical movement of the movable pad body that operates in the same manner as the top cymbal of the acoustic HH, and even if the movable pad body is lowered in a tilted state. The operation can be accurately detected by pressing the operation sensor with the actuator.

  According to the second aspect, more realistic motion can be detected by the stepwise detection.

  According to the third aspect of the present invention, it is possible to ensure reliable motion detection at the initial stage of contact with the motion sensor on the radially outer side having a wide laying range, and to detect motion at the later stage of contact when the inclination of the movable pad body is settled. With respect to the motion sensor, the construction can be simplified and the cost can be reduced as a minimum installation range.

  FIG. 2 is a right side view of the hi-hat electronic pad PD. Hereinafter, in the electronic pad PD supported horizontally, the player side is referred to as the front side, and the left-right direction is referred to as the direction viewed from the player. Each of the electronic pads PD includes a circular HH pad body PDT and a bottom pedestal 80 in plan view. The HH pad body PDT and the bottom pedestal 80 correspond to the top cymbal and the bottom cymbal in the acoustic hi-hat cymbal, respectively.

  FIG. 3 is a plan view of the HH pad body PDT, and FIG. 4 is a bottom view of the HH pad body PDT. 5 is a cross-sectional view taken along line AA in FIG. 3, FIG. 6 is a cross-sectional view taken along line BB in FIG. 3, and FIG. 7 is a cross-sectional view taken along line CC in FIG.

  First, a schematic configuration will be described. As shown in FIGS. 5 to 7, the HH pad body PDT mainly includes a pad portion pd, a back cover 70, and an operation detection unit UNT. The pad part pd is mainly composed of a frame 40 and a rubber pad 30 that provides a striking surface. The frame 40 is made of a hard material such as PP (polypropylene) that can cause extra vibration to be internally lost and can absorb the bending at the time of striking. The back cover 70 is made of a material softer than the frame 40, such as EVA (ethylene vinyl acetate resin), and is deformed along the bending of the frame 40 and suppresses unnecessary vibration after hitting.

  The HH pad body PDT is supported horizontally and swingably on the support portion 50. The support part 50 is fixed to a movable column 47 (see FIG. 9) that is erected on a stand (not shown). The movable strut 47 is lowered by a stepping operation of a pedal 48 (see FIG. 9), and when the stepping is released, it is lifted by a biasing means (not shown). Therefore, the support part 50 moves up and down integrally with the movable support 47 that moves up and down by a pedal operation. The structure of the stand from the movable support 47 to the pedal 48 is the same as that for the acoustic HH, and a commercially available one can be adopted.

  As shown in FIGS. 2 and 5, on the upper surface of the HH pad body PDT, a cup part pdc corresponding to the center part in the radial direction, a peripheral part pda corresponding to the edge part, and a ride between the cup part pdc and the peripheral part pda. An area (bow) pdb is provided as an area to be hit by a performance operation. The cup part pdc and the ride area pdb are hit with a stick exclusively, but the peripheral part pda is not only hit, but is also operated to be pinched from above and below by a finger (mute operation).

  In addition to the performance operation by these hands, in response to the operation of the pedal 48 (see FIG. 9), the motion detection unit UNT of the HH pad body PDT comes into contact with the bottom pedestal 80. Operation is also possible. In this embodiment, in particular, not only the front region of the HH pad body PDT but also the entire region including the left and right regions and the rear region are targeted for hit detection, and the mode of performance expression is expanded.

  Next, each configuration will be described in detail.

As shown in FIGS.
The support portion 50 mainly includes a felt support member 51 made of metal or the like, a non-rotating pin 54, felts 52 and 53, fixing nuts 56 and 57, and a column fixing member 59, which are integrally configured as a unit. It has become. The felt support member 51 is formed by integrally projecting a cylindrical portion 51d upward from a base portion 51a which is a flange portion. The base portion 51a and the cylindrical portion 51d may be fixed as a separate structure by screwing or the like. From the base portion 51a, a non-rotating pin 54 made of metal or the like protrudes rearward. The non-rotating pin 54 has an L shape in a side view in which a round bar is bent, and the tip extends vertically upward. A buffer material 55 such as vinyl chloride is coated around the vertical portion of the rotation prevention pin 54. The detent pin 54 may be formed integrally with the base 51a.

  As shown in FIG. 5, a through-hole 40 da and a rotation-preventing hole 40 c are formed in the supported portion 40 d that is the center portion in the radial direction of the frame 40. The anti-rotation pin 54 passes through the anti-rotation hole 40c of the frame 40 and is exposed upward. Accordingly, in the plan view, the rotation prevention pin 54 is surrounded by the inner wall of the rotation prevention hole 40c.

  The felt support member 51 is formed with an insertion hole 51c through which the movable column 47 (see FIG. 9) is inserted so as to penetrate from the base portion 51a to the entire tubular portion 51d in the vertical direction (see FIG. 9). 3, see also FIG. A male screw 51b is threaded on the outer peripheral side of the cylindrical portion 51d. The cylindrical portion 51d of the felt support member 51 passes through the supported portion 40d of the frame 40 with a clearance.

  On the base 51a of the felt support member 51, a donut-shaped felt 53 and a felt 52 are disposed in order with the supported portion 40d of the frame 40 interposed therebetween. A cylindrical portion 51d is inserted into each hole of the felts 53 and 52. The fixing nuts 56 and 57 (the fixing nut 56 is for preventing loosening and is not essential) are screwed onto the male screw 51 b of the felt support member 51 on the felt 52. Felts 52 and 53 are sandwiched and inserted between the fixing nut 57, which is a collar, and the base 51a with an appropriate force. As a result, the HH pad body PDT can swing with respect to the felt support member 51 through the elasticity of the felts 52 and 53, that is, swing in all directions including front, rear, left and right. By adjusting the fastening force by the fixing nuts 56 and 57, it is possible to adjust the degree of shaking of the HH pad body PDT at the time of impact.

  By the way, the outer shape of each of the base 51a of the felt support member 51, the felts 52 and 53, and the fixing nuts 56 and 57 is not limited. That is, it may not be circular as long as it does not penetrate the through hole 40da of the frame 40. Further, the fixing nuts 56 and 57 may be fixed to the cylindrical portion 51d as long as the fixing can be performed at a desired position in the vertical direction, not by a screwing method. Furthermore, the felts 52 and 53 should just be comprised with the elastic member, and are not restricted to the products made from felt.

  The support fixture 59 has an upper half part and a lower half part formed by horizontal slitting. In the lower half of the support fixture 59, a slit in the vertical direction is provided to form two fastening pieces 59b and 59c adjacent to each other (see FIG. 3). A female screw (not shown) corresponding to the male screw 51 b of the felt support member 51 is formed on the inner diameter portion of the lower half portion of the support fixture 59. The lower half portion of the support fixture 59 is screwed into the upper end portion of the felt support member 51, and the two fastening pieces 59b and 59c are fastened with screws 58 (see FIGS. 3, 5, and 7). The upper end portion of the felt support member 51 is tightened by the lower half portion of the support fixture 59. Thereby, the support fixture 59 is attached and fixed to the felt support member 51. The upper end of the cylindrical portion 51d is located near the upper end of the lower half portion of the column fixture 59.

  The support fixture 59 is provided with a tightening knob 49. By tightening the knob 49 (see FIGS. 2, 3 and 6) in a state where the movable column 47 (see FIG. 9) is inserted into the insertion hole 59a in the upper half of the column fixture 59, the knob is Since the tip of 49 presses the movable support 47 in the insertion hole 59a, the outer peripheral surface of the movable support 47 is in a pressure contact state with the inner peripheral surface of the insertion hole 59a. As a result, the entire support portion 50 is connected and fixed to the movable support 47 through the support fixture 59. Therefore, when the movable support 47 is moved up and down, the support portion 50 is moved up and down in conjunction therewith. Since the fixing mechanism of the support fixture 59 to the movable support 47 is the pressure contact mechanism as described above, even if the movable support 47 is a simple rod-like body without screws or the like, the support portion 50 is easily connected and fixed. be able to.

  In addition, as a mechanism which press-contacts the outer peripheral surface of the movable support | pillar 47 and the inner peripheral surface of the insertion hole 59a, it is not restricted to this example. For example, as with the lower half of the support fixture 59, a mechanism may be used in which the slit portion is pressed by tightening with a screw.

  By tightening or loosening the knob 49 in the support fixture 59, the support fixture 59 and the movable support 47 can be connected and fixed or released. At this time, even if the knob 49 is slightly loosened, the support portion 50 remains integral, so that the HH pad body PDT attached to the support portion 50 can be attached to and detached from the movable support 47 (attachment and removal). )can do.

  Further, in the support portion 50, the support member 59 and the fixing nuts 56 and 57 are unscrewed from the felt support member 51, and the felt support member 51 is pulled out relatively downward from the through hole 40 da of the frame 40. Thus, the HH pad body PDT is separated from the support portion 50. Thereby, the HH pad body PDT can be handled separately from the support portion 50, and is convenient, for example, not bulky at the time of sale or transportation.

  As shown in FIGS. 5 to 7, the rubber pad 30 is fixed to the upper side of the frame 40 with a double-sided tape or an adhesive (not shown). The rubber pad 30 extends from the upper side to the lower side of the frame 40 at the peripheral edge portion pda, and is fixed so as to sandwich the peripheral edge portion of the frame 40 from above and below. Further, the supported portion 40d of the frame 40 is located inside the cup corresponding portion 30a of the rubber pad 30 in the radial direction, and the supported portion 40d is exposed upward.

  FIG. 8A is a plan view of the frame 40, and FIG. 8B is a rear view of the frame 40. The frame 40 has a through hole 40da and has a circular shape in plan view. As shown in FIG. 8A, sheet sensors 31f and 31r are disposed on the upper surface 40a of the peripheral portion of the frame 40 by bonding or the like (see also FIGS. 1 and 5 to 7). The sheet sensor 31f is disposed in a region of more than half of the front side of the frame 40. On the other hand, the sheet sensor 31r is disposed in a region on the rear side of the frame 40 where the sheet sensor 31f is not disposed, and both the sheet sensors 31f and 31r have a substantially annular shape. From each sheet sensor 31f, 31r, sensor lead-out portions 31fa, 31ra are led out radially inward.

  As shown in FIG. 8A, a sheet sensor 37 is disposed on the upper surface 40a outside the supported portion 40d of the frame 40 in the radial direction. The sheet sensor 37 is disposed in a substantially annular shape at a position avoiding the rotation stop hole 40c. Each of the sheet sensors 31f, 31r, and 37 may be a film-type sensor that senses a pressure change and outputs a detection signal independently, and may be of any type such as a piezoelectric type or a capacitor type.

  Further, as shown in FIG. 8B, one piezo sensor 41 (see also FIGS. 1 and 5) is disposed on the back surface 40b side of the frame 40 by bonding or the like. The piezo sensor 41 is disposed on the lower surface of the portion corresponding to the ride area pdb slightly inside the peripheral edge of the frame 40. The piezo sensor 41 is composed of a piezoelectric element, but any type can be used as long as it can sense vibration.

  Further, signal output units 32 and 33 are disposed on the back surface 40 b side of the frame 40. A piezo sensor 41 is connected to the signal output unit 32 through a signal line 36, and the signal output unit 32 outputs a detection signal from the piezo sensor 41 to the outside from the output terminal 34. The signal output unit 32 is also electrically connected to sensor deriving units 31fa and 31ra (see FIG. 8A) and a sensor deriving unit (not shown) from the sheet sensor 37, and detection from these sensors is performed. The signal is output from the output terminal 34 to the outside. The signal output unit 33 outputs a detection signal from an operation detection unit UNT described later from the output terminal 35 to the outside.

  The piezo sensor 41 mainly detects vibration caused by hitting the ride area pdb, and outputs a detection signal indicating the presence / absence of the hit and its strength. The sheet sensor 37 detects an impact on the cup portion pdc and outputs a detection signal indicating the presence / absence of the impact and its strength. The sheet sensors 31f and 31r detect a hit with respect to the peripheral edge portion pda and a mute operation pressed from above and below, and output a detection signal indicating the presence or absence of the hit and the mute operation and the hitting strength.

  The sheet sensors 31f and 31r have the same width, and the width is uniform over the entire length. However, the width may be varied depending on the position. For example, on the left and right sides, the hitting position of the peripheral edge may not be accurate, so the width may be increased. Also, the sensitivity of both may be different. Alternatively, a sensitivity adjustment mechanism may be provided. Note that a design so that the boundary between the sheet sensors 31 f and 31 r can be recognized may be provided on the upper surface of the rubber pad 30. Further, a sheet sensor corresponding to the sheet sensor 31 may be further provided on the back surface 40b side of the frame 40 for detecting the mute operation.

  As shown in FIG. 3, the detent hole 40c of the frame 40 is a long hole that is long in the front-rear direction. The length of the anti-rotation hole 40c in the front-rear direction is L1, and the length in the left-right direction is L2, which is shorter than L1. On the other hand, the detent pin 54 passing through the detent hole 40c has a circular cross section. In the non-performance state, the rotation prevention pin 54 penetrates the rotation prevention hole 40c and protrudes upward. However, the anti-rotation pin 54 is disposed at a position near the center in the radial direction of the HH pad body PDT and slightly shifted from the center to the rear side, so that it does not interfere with the performance and may be annoying to the player. Absent.

  During performance, the HH pad body PDT can rotate in the horizontal direction with respect to the support portion 50. However, the rotation angle range of the HH pad body PDT is regulated by the abutment pins 54 coming into contact with and engaging the left and right inner walls of the detent hole 40c. On the other hand, the HH pad body PDT swings when hit, but the swing angle range is also restricted by the engagement of the rotation stop pin 54 and the rotation stop hole 40c.

  For example, when the foremost part of the HH pad body PDT is hit and the HH pad body PDT swings in the front-rear direction, the rotation prevention pin 54 comes into contact with and engages with the front and rear inner walls of the rotation prevention hole 40c. The swing angle range in the front-rear direction of the HH pad body PDT is restricted. When the left or right portion of the HH pad body PDT is hit and the HH pad body PDT swings in the left-right direction, the rotation prevention pins 54 come into contact engagement with the left and right inner walls of the rotation prevention hole 40c. Thus, the horizontal swing angle range of the HH pad body PDT is restricted. Similarly, even when the HH pad body PDT swings in an oblique direction instead of front, back, left, and right, the swing angle range is restricted according to the direction.

  Here, since L1> L2, the distance between the rotation prevention pin 54 and the inner wall of the rotation prevention hole 40c is larger in the front-rear direction than in the left-right direction. Therefore, the HH pad body PDT can swing larger in the front-rear direction than in the left-right direction. Thereby, the natural rocking | fluctuation can be produced by varying the maximum rocking | fluctuation amount of the HH pad body PDT with directions.

  Although a plurality of the piezo sensor 41 and the sheet sensors 31f, 31r, and 37 may output detection signals simultaneously by hitting the frame 40, it is arbitrarily set which sensor signal is used for the tone control. Is possible. For example, a sensor signal that outputs a signal indicating the largest value may be simply used for tone control. Further, the sheet sensors 31f and 31r may be used for detection exclusively for the mute operation or batting operation at the peripheral edge portion pda. Alternatively, the hitting may be detected in cooperation with the piezo sensor 41, and the detection signals of the sheet sensors 31f and 31r may be used for determining the hitting position. Alternatively, the detection of the impact on the cup part pdc may be performed exclusively using the signal detected by the piezo sensor 41 without using the output of the sheet sensor 37.

  In the present embodiment, as an example, the CPU 11 performs tone control as follows. First, the presence / absence (timing) of the hit and the hit position are comprehensively determined from the output signals of the sensors. Here, at the peripheral edge pda, it is also determined by the two sheet sensors 31f and 31r whether the hitting position is the front area or the rear area. In the ride area pdb, the seat sensors 31f and 31r also determine whether the ride area pdb is a front area or a rear area.

  The tone color to be generated is made different depending on which one of the front / rear region of the peripheral portion pda, the front / rear region of the ride area pdb, or the cup portion pdc is hit. As a result, a musical tone having a tone different from that of the front side is generated by striking on the rear side, so that the performance expression is expanded. Depending on the detection signal from each sensor, it is up to you to decide whether to give priority to the last-come-to-be-deleted musical tone or to duplicate it, but in this embodiment, as an example, Repeat pronunciation without erasing.

  As for the mute operation, for example, it is determined that the mute operation has been performed when a signal indicating that one of the sheet sensors 31f and 31r has been pressed for a certain period of time is output in a state where there is no response from the piezo sensor 41. When the mute operation is performed, attenuation control is performed for all the musical sounds that are sounding. Note that only the output signal of the sheet sensor 31f may be used for the mute operation.

  As shown in FIG. 4, the back cover 70 includes a base 73 that covers the radial center of the pad portion pd from below, and three arms that extend radially from the base 73 to the peripheral portion pda of the pad portion pd. 71 (71A, 71B, 71C) and are integrally formed. The back cover 70 is disposed on the back surface 40 b side of the frame 40. The front ends of the respective arm portions 71 of the back cover 70 are fitted into projecting portions 40e that protrude downward at the peripheral edge of the frame 40 (see FIGS. 5 to 7). Further, the back cover 70 is fixed to the frame 40 by a plurality of screws 72. The back cover 70 may be bonded to the frame 40. The length of each arm 71 is at least half the radius of the HH pad body PDT.

  The back cover 70 plays a role of transmitting vibration of the pad portion pd in cooperation with the frame 40. As shown in FIGS. 4 and 8B, the piezo sensor 41 is disposed at a position where one arm portion (arm portion 71A) is present in plan view. Thereby, the striking vibration generated in the pad portion pd is appropriately and efficiently transmitted to the striking detection means. Moreover, as shown in FIG. 4, the signal output parts 32 and 33 are arrange | positioned in the position with separate arm parts 71B and 71C, respectively in planar view. Further, the signal line 36 (see FIG. 8B) is hidden from the lower side mainly by the base 73 of the back cover 70. Accordingly, the piezo sensor 41, the signal output units 32 and 33, and the signal line 36 are protected and do not appear in the appearance.

  Moreover, since the signal output units 32 and 33 and the piezo sensor 41 are disposed at different arm portions 71, it is easy to improve the weight balance of the entire HH pad body PDT. The shape including the thickness of each arm 71 may be different. Since the arm portion 71 is radial, for example, it is easy to design a different shape in order to set the weight balance of the entire HH pad body PDT as desired.

  At the time of a strong impact, the flexure of the pad portion pd generates a vibration separately from the direct vibration due to the impact. The back cover 70 also functions to moderately attenuate the vibration of the pad portion pd and suppress malfunction caused by vibration due to bending. If the back cover 70 has a circular shape in plan view and extends to the peripheral edge portion pda of the pad portion pd, the vibration suppressing effect of the pad portion pd is high. However, if it is circular, the vibration generated in the peripheral edge portion pda may be dispersed or absorbed more than necessary by the back cover, and the striking vibration may not be properly transmitted to the piezo sensor 41 in some cases.

  Therefore, in the present embodiment, the back cover 70 is formed in a radial shape, and the arm portion 71 is extended to the peripheral edge portion pda of the pad portion pd. Thereby, harmful vibrations can be effectively suppressed without excessively impeding the transmission of impact vibrations. In addition, the weight can be reduced as compared with the circular shape, and the weight of the back cover 70 can be collected at the center of the HH pad body PDT to make the swing of the HH pad body PDT more natural.

  By the way, the outer end positions of the signal output portions 32 and 33 in the radial direction of the HH pad body PDT are both located on the inner side of the most distal positions of the arm portions 71B and 71C. Since these output terminals 34 and 35 come out from the side of the signal output parts 32 and 33, they are similarly located inside the foremost positions of the arm parts 71B and 71C. As a result, the vicinity of the peripheral edge of the HH pad body PDT is suppressed from becoming unstable due to the cords connected to the output terminals 34 and 35 being heavy. In addition, inhibition of free movement of the HH pad body PDT due to the weight of the cord is also suppressed.

  FIG. 9 is a partial cross-sectional view of the HH pad body PDT including the bottom pedestal 80 along the line DD in FIG. The motion detection unit UNT is the lowermost part of the HH pad body PDT and is disposed below the back cover 70 (see FIGS. 2, 4 to 7, and 9). As shown in FIG. 9 and the like, each of the motion detection units UNT includes a donut-shaped substrate 60 in plan view and a rubber-based elastic portion 63 disposed on the lower side of the substrate 60.

  An outer edge portion that is also an upper portion of the elastic portion 63 is formed with a pinching portion 66 that is concave on the inside, and a protrusion-like engaging portion 67 that is connected to the pinching portion 66 and protrudes outward. ing. A plurality of pins 45 project from the upper surface side of the substrate 60 (see FIGS. 5 to 7 and 9), and these pins 45 are fitted to the frame 40. Thereby, the substrate 60 is fixed to the frame 40. Further, the peripheral edge portion of the substrate 60 is sandwiched from above and below by the sandwiching portion 66. Further, the engaging portion 67 of the elastic portion 63 is engaged with the back cover 70. In this way, the motion detection unit UNT is fixed to the frame 40 and the back cover 70.

  FIG. 10A is a plan view of the elastic portion 63. FIG.10 (b) is sectional drawing which follows the EE line | wire of Fig.10 (a). As shown in FIGS. 9, 10A, and 10B, the elastic portion 63 has a through hole 63a in the center in the radial direction, and further, a skirt portion 64B that is a thin portion around the lower portion of the through hole 63a, It has a thick base 65 radially outward from the skirt 64B and a skirt 64A that connects the base 65 to the outer edge. The lower surface of the base 65 is inclined downward as it goes inward in the radial direction.

  An escape portion 63aa is connected to the through hole 63a in the same direction as the extending direction (backward) of the root portion of the rotation stopper pin 54 of the support portion 50 (see FIGS. 4 and 10A). When the HH pad body PDT with the motion detection unit UNT attached is attached to or detached from the support portion 50, interference between the elastic portion 63 and the detent pin 54 is avoided by the escape portion 63aa. That is, the outer diameter of the cylindrical portion 51d of the felt support member 51 of the support portion 50 is smaller than the through hole 40da of the frame 40 and has a clearance. Therefore, when inserting / removing the felt support member 51 into / from the through hole 40da, the felt support member 51 is moved slightly forward relative to the HH pad body PDT, so that the elastic portion 63 is prevented from rotating. The HH pad body PDT can be attached and detached without interfering with 54. Note that the escape portion 63aa may be designed to be sufficiently large so that the felt support member 51 can be inserted and removed straight without shifting.

  The elastic part 63 is made of an elastic material harder than the rubber pad 30, but when pressed in the vertical direction, the entire base part 65 is displaced upward mainly by the elasticity of the skirt parts 64A and 64B. As a result, the base 65 approaches and separates from the substrate 60. Actuators 68 (68A to 68E) are integrally formed on the upper surface of the base 65 so as to project. The actuators 68A are projected at all four concentric positions on the front, rear, left, and right with the radial center of the elastic portion 63 as the center, and the actuators 68B to 68E are projected at two positions on the left and right. The actuators 68A to 68E are located in this order from the radially outer side to the inner side.

  As shown in FIG. 10B, the upper end position is lower in the order of the actuators 68A to 68E, and the actuator 68A is the highest. In addition, stoppers 69 are provided at four positions on the left and right sides of the diagonally front and left and right sides of the diagonally back at positions concentric with the actuator 68E. Although the height of the stopper 69 is not shown, it is the same height as the actuator 68D.

  FIG. 11A is a bottom view of the substrate 60. FIG.11 (b) is sectional drawing which follows the FF line | wire of Fig.11 (a). The substrate 60 has a through hole 60b in the center in the radial direction. A plurality of sheet switches 61 (61 </ b> A to 61 </ b> E) corresponding to the actuators 68 </ b> A to 68 </ b> E of the elastic portion 63 are laid in a planar manner on a laying surface 60 a that is a flat lower surface of the substrate 60. On the left side of the rear half of the substrate 60, a sensor lead-out section 46 is led out from each sheet switch 61, and the sensor lead-out section 46 is connected to the signal output section 33 (FIGS. 4, 6, and 8B). Yes.

  The seat switches 61A to 61E have concentric substantially circular or arc shapes with different radii of curvature (different radial positions) in plan view, and are arranged in the order of the seat switches 61A to 61E from the outside in the radial direction to the inside. It is installed. The outermost seat switch 61A has an annular shape except for a portion where the sensor lead-out portion 46 is arranged in plan view, and is also referred to as “substantially annular”. Next, the inner seat switch 61B is the same, but the laying length of the seat switch 61A is slightly longer due to the difference in the radius of curvature. The seat switches 61C to 61E are divided into left and right and are laid at two locations. Each of the sheet switches 61C to 61E has an arc shape, and the outer switch has a longer arc length.

  As will be described later, by the pedal operation, the corresponding actuators 68A to 68E of the elastic portion 63 come in contact with the seat switches 61C to 61E. When each actuator 68 abuts against and presses the corresponding sheet switch 61, each sheet switch 61 outputs a signal indicating that the operation is on. The configuration of each seat switch 61 is the same. As an example, the configuration of the sheet switch 61A will be described. As shown in FIG. 11B, a spacer 42 is interposed between the lower sheet 43 and the upper sheet 44, and a space portion without the spacer 42 constitutes a sheet switch 61A. When the contact portions 43a and 44a provided on the opposing surfaces of the lower sheet 43 and the upper sheet 44 come into contact with each other, a signal indicating that is output, thereby detecting the on state of the operation.

  In the motion detection unit UNT, five sets of the sheet switch 61 and the corresponding actuator 68 are configured. Since the laying surface 60a is horizontal, in the state where the pedal operation is not performed, the distance between the seat switch 61 and the actuator 68 in the radially outer group is smaller (see FIGS. 9 and 10A). When the base portion 65 is raised by the pedal operation, the detection signal is output by being pressed by the corresponding seat switch 61A in order from the outer side seat switch 61A in the radial direction.

  As shown in FIG. 9, the bottom pedestal 80 is supported by the pedestal support portion 84. An insertion hole 84 b is formed at the center of the pedestal support portion 84. The pedestal support portion 84 is fixed to a stand (not shown) with a predetermined fixing tool in a state where the movable column 47 is slidably inserted into the insertion hole 84b, and does not move up and down even during performance. Note that the pedestal support portion 84 may be arranged in any manner as long as the position in the vertical direction is fixed with respect to the installation surface and the movable support 47 is allowed to move up and down. When the pedal 48 is depressed, the movable support 47 slides up and down in the insertion hole 84b. A positioning column 85 protrudes upward from the center of the base support portion 84 in the radial direction.

  On the other hand, the bottom pedestal 80 includes a weight part 81 made of a metal such as aluminum and an elastic member 82, is configured in a donut shape, and has a substantially inverted trapezoidal shape in a side view. The weight part 81 is not limited to metal, and may be made of a material having a certain weight. The elastic material 82 is made of an elastic material such as a rubber material or a hard sponge, but is harder than the elastic portion 63 of the motion detection unit UNT. It is preferable that the material or the configuration be such that it is difficult to be elastically deformed at the beginning when it receives the pressing force and is elastically deformed with a light force once the deformation starts.

  A concave portion 81a is formed in the lower portion of the weight portion 81, and an elastic material 82 is fitted in the concave portion 81a. A thin sliding material 83 is attached to the upper portion of the weight portion 81. Then, the positioning column 85 protruding upward from the pedestal support portion 84 is inserted into the hole in the center in the radial direction of the bottom pedestal 80, and the lower surface 82 a of the elastic material 82 is placed on the support surface 84 a that is the upper surface of the pedestal support portion 84. It is in contact. Therefore, the bottom pedestal 80 is not fixed with respect to the pedestal support portion 84, and is merely placed.

  In this state, a distance CL is ensured between the flat upper surface 80a of the bottom pedestal 80, which is also the upper surface of the sliding member 83, and the lowermost end of the elastic portion 63 of the motion detection unit UNT. Accordingly, the bottom base 80 is separated from the HH pad body PDT, and is disposed immediately below the HH pad body PDT. The distance CL can be arbitrarily adjusted by adjusting the vertical position of the HH pad body PDT with respect to the movable support 47 or by adjusting the vertical position of the pedestal support portion 84 with respect to a stand (not shown). The sliding member 83 is disposed in a range that can sufficiently cover the entire range in which the elastic portion 63 can abut on the basis that the HH pad body PDT descends while swinging.

  As the sliding material 83, a film based on ultra high molecular weight polyethylene is employed. The sliding material 83 may be any material as long as the elastic portion 63 is in sliding contact with the pedal when operated, and is not limited to the above material. That is, a material having a smooth surface such as a seal mount and high self-lubricating property and wear resistance is desirable. In addition, although the sliding material 83 was made into the sheet form, there is no restriction | limiting in thickness. Further, the above-described materials are also examples, and metals may be used. Alternatively, the upper surface of the weight portion 81 may be coated with fluorine, nylon resin, polyurethane resin, or the like. Alternatively, the material of the weight part 81 may be a material having a sliding function as described above, and a portion corresponding to the sliding material 83 may be configured integrally with the weight part 81.

  In such a configuration, when the player steps on the pedal 48 (see FIG. 9), the HH pad body PDT is lowered together with the movable support 47 in the pedal operation forward stroke, and the elastic portion 63 of the motion detection unit UNT is the upper surface of the bottom pedestal 80. It abuts on 80a. At that time, the HH pad body PDT may be swung by striking with a stick in advance, and does not necessarily descend horizontally but may tilt at the time of contact. Even in such a case, due to the lubricity of the sliding material 83, the elastic portion 63 smoothly slides with respect to the upper surface 80a of the bottom pedestal 80, and the posture of the HH pad body PDT is automatically leveled. Is done.

  Regarding detection of the seat switch 61, first, in the pedal operation forward stroke, the actuator 68A contacts the outermost seat switch 61A, and a detection signal is output. In particular, since the actuator 68A is disposed at four positions on the front, rear, left and right sides spaced apart in the circumferential direction (see FIG. 10A), the HH pad body PDT is in the initial contact between the elastic portion 63 and the bottom base 80. Even if it is tilted in any direction, any of the actuators 68A can contact and press the corresponding sheet switch 61A to detect ON. In addition, although the elastic portion 63 is slightly deformed, the seat switch 61A is configured to be substantially annular, so that even if the contact position of the actuator 68A is slightly deviated in the circumferential direction, the seat switch 61A is reliably pressed. be able to.

  In the pedal operation forward stroke, when the actuator after the next actuator 68B comes into contact with the actuator after the sheet switch 61B, the posture of the HH pad body PDT is corrected almost horizontally. Even if it is not, it will contact reliably. Accordingly, the actuator 68A to the actuator 68E sequentially contact the corresponding sheet switch 61, and the operation on is detected in order. In the pedal operation forward stroke, the angle of the lower surface of the base 65 gradually approaches horizontal, and when all the pairs are turned on, the lower surface of the base 65 becomes substantially horizontal.

  In addition, the stopper 69 comes into contact with the laying surface 60a of the substrate 60 at the same time as the contact of the actuator 68D and the sheet switch 61D which are the fourth stage from the first contact set. The sheet switch 61 is not disposed in a portion of the laying surface 60a of the substrate 60 where the stopper 69 abuts. After the stopper 69 comes into contact with the laying surface 60a, the actuator 68E comes into contact with the seat switch 61E by further stepping in while feeling resistance. Thereby, a real feeling of pedal operation is obtained.

  The sheet switch 61B may also have an arc shape like the sheet switches 61C to 61E. Alternatively, if the design of the actuator 68B and the sheet switch 61B is turned on by design and the inclination of the HH pad body PDT cannot be sufficiently corrected, the actuator 68B is also provided at four locations in the same manner as the actuator 68A. Certainty increases.

  In the performance of the electronic pad PD, an open hi-hat that strikes the pad part pd with a stick without operating the pedal, a closed hi-hat that strikes the pad part pd with the stick while the pedal 48 is depressed, and no stick is used. In addition, there is pedal striking that produces a sound just by depressing the pedal 48.

  How to control the musical tone according to the detection output of the operation of each seat switch 61 is arbitrary, but the following is given as an example. For example, when an operation such as hitting the pad portion pd is detected by the piezo sensor 41 and the sheet sensors 31f, 31r, and 37 (see FIG. 1 and the like) in a state where the sheet switch 61A is not turned on, it is processed as an open hi-hat. , Generate a sound corresponding to it. If any of the seat switches 61 is turned on and a hit of the pad portion pd is detected, it is treated as a closed hi-hat, and the innermost one of the seat switches 61 that are turned on at that time is selected. A musical tone is generated with a different tone. In particular, when the innermost one is the sheet switch 61D, the tone is the same as that of the closed hi-hat in the acoustic HH.

  At the time of pedal striking, for example, a musical sound corresponding to pedal striking is generated when the seat switch 61D is turned on. The sound volume at that time is set according to, for example, the time from turning on a predetermined seat switch (defined one of the seat switches 61A to 61C) to turning on the seat switch 61D in the pedal operation forward stroke. .

  Further, when a pedal on / off operation is performed while the pad portion pd is struck and sounded, the timbre may be changed in real time according to the seat switch 61 in which on / off is detected. By the way, when the mute operation is detected by the sheet sensors 31f and 31r, the musical sound produced by the pedal striking is also attenuated.

  By the way, in the pedal operation forward stroke, the elastic portion 63 of the motion detection unit UNT is elastically deformed via the skirt portions 64A and 64B (see FIG. 9). Thereby, a reaction force against the pedal operation (referred to as “first reaction force”) is generated. Thereafter, when the stopper 69 comes into contact with the substrate 60, the elastic portion 63 itself does not elastically deform so much. On the other hand, when the elastic portion 63 comes into contact with the bottom pedestal 80, the elastic material 82 of the bottom pedestal 80 starts to receive a pressing force from the support surface 84a of the pedestal support portion 84. Strictly speaking, the elastic material 82 is also slightly elastic. Start transforming. However, since the rigidity of the elastic member 82 is sufficiently larger than the skirt portions 64A and 64B of the elastic portion 63, the elastic member 82 hardly elastically deforms until the stopper 69 comes into contact with the substrate 60 in the pedal operation forward stroke.

  However, when the stopper 69 comes into contact with the substrate 60, the pressing force received by the elastic member 82 from the pedestal support portion 84 rapidly increases, so that the elastic member 82 starts macroscopic elastic deformation. That is, the elastic member 82 undergoes macroscopic elastic deformation after the elastic portion 63 is elastically deformed by a predetermined amount. Due to macroscopic elastic deformation of the elastic member 82, a second reaction force is generated behind the first reaction force.

  Here, in the acoustic HH cymbal, the top cymbal comes into contact with the bottom cymbal by the pedal operation and a reaction force is generated. When the pedal is further depressed, the reaction force rises and then each cymbal is bent slightly in the direction of turning over. The reaction force change due to turning over is pleasant to the player, and further, the reaction force change can be felt and the depression can be stopped with an appropriate strength.

  The reaction force generated from when the top cymbal comes into contact with the bottom cymbal until it begins to bend in the reverse direction corresponds to the “first reaction force” described above. The reaction force generated after both cymbals begin to bend in the reverse direction corresponds to the “second reaction force” described above. Thereby, realistic reaction force change with respect to pedal operation similar to acoustic HH can be produced. In addition, since a preferable reaction force change is a sensory thing, how to set the magnitude | size of a 1st reaction force and a 2nd reaction force is arbitrary.

  According to this embodiment, the rocking angle range of the HH pad body PDT is regulated by the engagement between the rotation prevention pin 54 of the support portion 50 and the rotation prevention hole 40c of the frame 40, The controlled swing angle range is different between the front-rear direction and the left-right direction (see FIGS. 3 and 5). As a result, it is possible to vary the maximum swing amount of the HH pad body PDT according to the direction, thereby generating natural and appropriate swing. In particular, in the present embodiment, not only the front part of the pad part pd but also the left and right side parts are considered as hitting ranges, and the swing angle of the HH pad body PDT is determined by hitting on the front side and hitting on the left or right side. The range can be different.

  Further, the rotation angle range of the HH pad body PDT is restricted by the engagement between the rotation prevention pin 54 and the rotation prevention hole 40c. As a result, the mechanism that restricts the swing of the HH pad body PDT also serves as a rotation stop function, so that the rotation stop can be realized with a compact configuration. In addition, since the swing and rotation prevention mechanism is configured by penetrating the rotation prevention pin 54 made of a rod-like member through the rotation prevention hole 40c which is a through hole, the configuration is simple.

  According to the present embodiment, the back cover 70 has the three arm portions 71 extending radially from the base portion 73 to the peripheral edge portion pda of the pad portion pd (see FIG. 4). The natural oscillation can be realized by collecting the weight at the center of the electronic pad. In addition, since the piezo sensor 41 is arranged at a position where one arm portion 71 (arm portion 71A) of the back cover 70 is located, the striking vibration can be transmitted to the piezo sensor 41 appropriately and efficiently.

  Further, since the signal output units 32 and 33 are respectively arranged at positions where the arm portions 71 (arm portions 71B and 71C) of the back cover 70 are present in plan view and covered by the arm portions 71 from below, the signal output units While protecting 32 and 33, an external appearance can be improved. In particular, the signal output units 32 and 33 are arranged at positions where there are different arm portions, and these arm portions are also different from the arm portion 71A where the piezo sensor 41 is arranged. It is easy to improve. Further, since the signal line 36 (see FIG. 8B) is hidden from below by the back cover 70, the signal line 36 is protected and the appearance is improved. As long as the signal output units 32 and 33 are protected and the appearance is improved, the two signal output units 32 and 33 and the piezo sensor 41 may be arranged so as to be hidden by the same arm unit 71.

  According to the present embodiment, the sheet sensor 31f is disposed in the front half or more of the periphery of the frame 40 of the HH pad body PDT, while the sheet sensor 31r is disposed in the rear area. And each outputs a detection signal independently. Thereby, separately from the peripheral edge part pda of the front part of the pad part pd, it is possible to detect the hit and mute operation hits on the rear part of the pad part pd and the left and right peripheral edge parts pda, and the performance expression power can be expanded. .

  Also according to the present embodiment, the bottom pedestal 80 is fixed, and the HH pad body PDT moves up and down by pedal operation, so that the operation modes are the same as the bottom cymbal and top cymbal of the acoustic HH, respectively. The appearance of the operation when the pedal is struck can be brought close to the acoustic HH cymbal.

  Further, since the seat switch 61A is substantially annular (see FIG. 11), and the actuator 68A is arranged at four positions on the front, rear, left and right sides separated in the circumferential direction (see FIG. 10A), the HH pad. Even if the body PDT is lowered in a tilted state or the elastic portion 63 is slightly deformed, the pedal operation can be accurately detected by reliably pressing the seat switch 61A by the actuator 68A.

  In addition, since each actuator 68 is present at two (or four) positions that are the farthest apart on the circumference corresponding to the sheet switch 61, the actuator 68 operates even if the HH pad body PDT is lowered in any direction. Can be accurately detected.

  From the viewpoint of accurately detecting the operation even when the HH pad body PDT is lowered in an inclined state, the actuator 68 is a range along the circumferential direction corresponding to the corresponding sheet switch 61 in plan view. In addition, it is preferably provided within the laying range of the sheet switch 61 and provided in at least two locations that are farthest apart on the circumference. The number is not limited. In addition, the actuator 68 may be configured as a plurality of protruding portions as illustrated, but may be configured in a ridge shape in an annular shape or a shape close thereto.

  On the other hand, the seat switch 61A is substantially annular, but is not limited to an annular shape. In other words, in consideration of the inclination of the HH pad body PDT and the deformation of the elastic portion 63, it is sufficient to lay it on the laying surface 60a of the substrate 60 on which the actuator 68A can abut.

  Also according to the present embodiment, since the vertical movement of the HH pad body PDT itself that operates in the same manner as the top cymbal of the acoustic HH is detected, a realistic detection is possible, and the relationship between the pedal performance and the generated musical sound is This is close to the acoustic HH. Moreover, realistic detection similar to that of the acoustic HH can be performed by the piezo sensor 41 or the like even when the stick is hit.

  Further, in the operation detection unit UNT, in the pedal operation forward stroke, a contact is sequentially made from the radially outer set of actuator 68 and seat switch 61, and a detection signal is output. Can be detected.

  As for the seat switch 61, the inner one in the radial direction is laid intermittently in the circumferential direction, and the outer one in the radial direction has a wider laying range in the circumferential direction and is closer to an annular shape. This ensures reliable operation detection at the initial contact between the motion detection unit UNT and the bottom pedestal 80 with the seat switch 61 on the radially outer side having a wide laying range, and the contact late stage in which the inclination of the HH pad body PDT is settled. For the seat switch 61 on the inner side in the radial direction for detecting the operation, the configuration can be simplified and the cost can be reduced as a minimum laying range.

  Also according to the present embodiment, since the sliding material 83 is attached to the upper part of the bottom pedestal 80 with which the elastic part 63 of the motion detection unit UNT abuts, the posture of the HH pad body PDT that can be lowered in the inclined state is set. It is possible to correct the movement by the smooth sliding contact on the upper surface 80a of the sliding member 83, and to detect the movement accurately.

  According to the present embodiment, the HH pad body PDT and the bottom pedestal 80 are configured separately, and the motion detection unit UNT having the seat switch 61 for detecting pedal operation is unitized and provided in the HH pad body PDT. It was. Further, a piezo sensor 41 and sheet sensors 31f, 31r, 37 for detecting stick hitting are connected to the signal output unit 32 through the signal line 36, sensor derivation units 31fa, 31ra, etc., and a sensor derived from the sheet switch 61. Together with the signal output unit 33 (FIGS. 4, 6, and 8B) to which the derivation unit 46 is connected, the HH pad body PDT is provided.

  Thereby, the signal output unit 33 and the sensor deriving unit 46 related to the signal output by the pedal operation are integrated into the HH pad body PDT together with the signal output unit and the wiring related to the signal output by the stick hitting to facilitate management. be able to. In other words, in the conventional configuration, when sensors are provided for the top cymbal and pedal, the wiring and signal output section are divided into two locations, upper and lower, which makes the configuration complicated and increases the number of parts. The wiring is complicated and easily caught. However, in the present embodiment, all signal output units and wirings are concentrated and arranged in the HH pad body PDT. Therefore, in the HH pad body PDT that performs the same operation as the top cymbal of the acoustic HH, While making it possible to detect pedal strikes realistically, it is possible to easily manage the handling of wiring and output terminals. Note that the HH pad body PDT need not be circular in plan view, and may be, for example, a fan shape, as long as it is easy to manage.

  According to the present embodiment, the first reaction force is generated when the elastic portion 63 of the motion detection unit UNT elastically deforms via the skirt portions 64A and 64B (see FIG. 9) in the pedal operation forward stroke. After the stopper 69 of the motion detection unit UNT comes into contact with the substrate 60, the elastic member 82 of the bottom pedestal 80 starts macroscopic elastic deformation and generates a second reaction force. By such a two-stage reaction force change, a reaction force change with respect to the pedal operation similar to the acoustic HH is generated, and a pedal operation feeling with a little uncomfortable feeling can be realized. In addition, if it restrict | limits to this viewpoint, the HH pad body PDT may not be circular in planar view.

  Further, the timing at which the stopper 69 abuts against the substrate 60 is designed to coincide with the abutment between the actuator 68D and the sheet switch 61D, which is the fourth (predetermined) stage group. Thereby, the timing of detection of the closed hi-hat by the seat switch 61D and the start of the second reaction force generation can be matched to realize a more realistic pedal operation feeling. From this point of view, matching the contact timing with the timing at which the stopper 69 contacts the substrate 60 is not limited to the combination of the actuator 68D and the sheet switch 61D, and can be arbitrarily designed. For example, a set of the actuator 68E and the sheet switch 61E may be used. The number of sets is not limited to five, but even if the number of sets is other than five, the set that matches the contact timing with the stopper 69 is preferably one or more sets before the last set. Is desirable.

  In addition, the motion detection unit UNT that generates the first reaction force also has a function of detecting the motion of the HH pad body PDT by the pedal operation, so that a realistic detection of the vertical motion of the HH pad body PDT can be performed with a compact design. It can be carried out.

  In addition, since the elastic material 82 that generates the second reaction force is provided in a portion of the bottom pedestal 80 that is supported by the pedestal support portion 84, the bottom pedestal 80 supports the pedestal by the elasticity of the elastic material 82 when the pedal is turned off. It is easily adsorbed by the portion 84. Accordingly, the bottom pedestal 80 is prevented from being taken away by the HH pad body PDT, and the bottom pedestal 80 can be supported by placing or the like without being fixed to the pedestal support portion 84, and the configuration and handling are simple. .

  Further, according to the present embodiment, the support portion 50 is integrally configured including the detent pin 54 (see FIG. 5), and the HH pad body PDT supported by the support portion 50 is connected to the support portion 50. , And can swing while the relative rotation is restricted. In addition, the support 50 mounted with the HH pad body PDT can be attached to and detached from the movable column 47 of the stand by operating the knob 49 in the column fixture 59. Moreover, the movable column 47 can be fixed to the upper half of the column fixing tool 59 by a simple pressure contact mechanism. Therefore, since the movable support 47 may be a simple rod-shaped body, a commercially available stand can be used for general purposes. Therefore, the HH pad body PDT can be easily attached to and detached from a commercially available stand in a state in which the swinging and detent functions are secured. Further, since the HH pad body PDT can be handled separately from the support portion 50, the HH pad body PDT is convenient without being bulky at the time of sale or transportation.

  In the present embodiment, the position at which the detent pin 54 (see FIG. 5) protrudes does not have to be the base 51a, and protrudes from a fixed position with respect to the movable column 47. That's fine.

  Note that the motion detection unit UNT detects the vertical motion of the HH pad body PDT using the combination of the actuator 68 and the sheet switch 61. However, the detection mechanism is not limited to this, and the signal is caused by being pressed. Can be output. For example, instead of the sheet switch 61, a fixed contact pattern may be provided, and a contact type switch provided with a movable contact at the tip of the actuator 68 may be used. Further, as long as the detection function is secured, the actuator 68 and the seat switch 61 may be reversed in the vertical relationship.

  From the viewpoint of detecting the realistic motion similar to that of the top cymbal, the motion detection unit UNT may be fixedly disposed at a position corresponding to the bottom cymbal as well as bringing the appearance of the motion closer to the acoustic HH cymbal. Good. In that case, a portion corresponding to the sliding material 83 is disposed in a portion disposed on the HH pad body PDT and in contact with the motion detection unit UNT.

  In the present embodiment, the first reaction force is generated by the motion detection unit UNT, and the second reaction force approximated to the flipping of the hi-hat cymbal is generated by the bottom pedestal 80. From the viewpoint of approximating the force change to an acoustic one, the place where the reaction force generation mechanism is provided does not matter. Each may be provided on either side of the HH pad body PDT or the bottom pedestal 80, and the provided side may be the same. There is no limitation on the positional relationship. Further, the number of reaction force generation mechanisms may be three or more, and three or more step changes may be realized. In addition, as far as reaction force is generated, the elastic member 82 of the bottom pedestal 80 may be provided not on the lower side of the bottom pedestal 80 but on the upper side, and may be brought into contact with the motion detection unit UNT.
