In FIG. 3, the right side of the drawing shows the “right” side of the electronic hi-hat cymbal 1, and the left side of the drawing shows the “left” side.

  As shown in FIGS. 1 to 3, the electronic hi-hat cymbal 1 is disposed so as to face the top cymbal pad portion 100, which is a pad hit by a player with a stick or the like, and below the top cymbal pad portion 100. Bottom cymbal pad portion 200, stand portion 400 that supports top cymbal pad portion 100 and bottom cymbal pad portion 200, first fixing means 500 that fixes top cymbal pad portion 100 to extension rod 420, and stand portion 400 The bottom cymbal pad portion 200 is fixed to the hollow shaft 410 by second fixing means 600 and the like.

  The stand part 400 has a structure similar to that of a general hi-hat cymbal stand. For example, as shown in FIG. 1, a hollow shaft 410 capable of adjusting the installation height of the bottom cymbal pad part 200, and its hollow An extension rod 420 that is inserted through the shaft 410 and moves up and down in response to an operation of a stepping pedal (not shown) is connected to the lower portion of the hollow shaft 410 as a member (not shown) to support the stand 400 standing up. It has leg parts to do.

  A felt holding part 411 and a lower felt washer 412 for installing the bottom cymbal pad part 200 are provided at the upper end of the hollow shaft 410, and the bottom cymbal pad part 200 is disposed on the upper side of the lower felt washer 412. The second fixing means 600 is fixed so as to be swingable. On the other hand, the top cymbal pad portion 100 is fixed to a predetermined position of the extension rod 420 so as to be swingable by a first fixing means 500 described later. Note that the manner of fixing the top cymbal pad unit 100 and the bottom cymbal pad unit 200 to the stand unit 400 will be described later.

  Hereinafter, the structure of the top cymbal pad portion 100 will be described with reference to FIGS. 4 to 5 in addition to FIGS. 4 is a front view of the lower surface side of the top cymbal pad portion 100, and FIG. 5 is a partially enlarged view of a peripheral portion including the edge slip tube 140 and the edge slip film 212 in the cross-sectional view of FIG. In the present embodiment, “the upper surface of the top cymbal pad portion 100” and “the lower surface of the top cymbal pad portion 100” indicate the upper surface and the lower surface in a state where they are attached to the stand portion 400, respectively. Are also used in the same meaning.

  The top cymbal pad portion 100 has a substantially circular shape in front view on the upper surface side or the lower surface side, and a cup portion 100a having a dome-like shape in the vicinity of the center on the upper surface side, and an edge portion that is an outer peripheral edge of the top cymbal pad portion 100 100c and a bow part 100b between the edge part 100c and the cup part 100a.

  As shown in FIG. 1, the top cymbal pad portion 100 includes a first top frame 101 that forms the skeleton, a cover 103 that covers the first top frame 101, and an insertion hole 102 b through which the extension rod 420 is inserted. It has a second top frame 102 and a vibration sensor mounting frame 120 for mounting a vibration sensor 110 (for example, a piezo element).

  The cover 103 is formed of an elastic body such as rubber or elastomer that covers the upper surface side of the top cymbal pad portion 100 and a part of the lower surface side such as the edge portion 100c. By this cover 103, the upper surface of the top cymbal part 100 forms a dish-like appearance having a cup part 100a that is raised one step, and a bow part 100b and an edge part 100c that are uniformly flat. In addition, on the upper surface side of the top cymbal pad portion 100, concentric uneven processing (not shown), for example, uneven processing with a groove width of 2 mm, a pitch of 4 mm (groove and groove width), and a depth of 0.1 mm is performed. It has been subjected.

  In addition, a rubber primer (reactive surface modification treatment agent) or the like is applied to the upper surface portion of the cover 103 by a method such as dipping, brushing, spraying, or the like, so that the surface modification treatment is performed. ing. Such a surface modification treatment makes it possible for the stick that strikes the top cymbal pad portion 100 to be slippery, and also improves the wear resistance of the cover 103. Accordingly, the feeling of sliding of the stick at the time of striking is close to the feeling at the time of striking a metal acoustic cymbal, and wear of the cover 103 due to long-time striking can be reduced. As described above, when the top cymbal pad portion 100 whose upper surface is covered with the cover 103 is hit with a stick, the stick jumps up naturally as when an acoustic hi-hat cymbal is hit.

  The first top frame 101 is a frame molded from, for example, a hard plastic material such as acrylonitrile-butadiene-styrene (ABS) resin or polycarbonate resin, and has an opening 101a at the center thereof. It has a dish shape.

  As shown in FIG. 1, the first top frame 101 has a shoulder portion 101b provided around the opening 101a and an arm portion 101c extending from the shoulder portion 101b toward the outer periphery. A step 101d provided on the outer peripheral side of the arm portion 101c and an outer peripheral portion 101e are provided at a position lowered by the step 101d on the front half of the pad portion 100.

  Since the front half of the top cymbal pad portion 100 is formed with a step 101d and an outer peripheral portion 101e, the cover 103 covering the upper side of the outer peripheral portion 101e is thicker than the other portions. Therefore, the vibration of the first top frame 101 due to the impact of the top cymbal pad portion 100 can be made uniform, and the vibration of the outer peripheral portion 101e is suppressed. Therefore, even when the top cymbal pad portion 100 is repeatedly hit, the hitting position and hitting force for each hit can be accurately detected.

  In addition, the cover 103 extends further outward than the outer peripheral portion 101e of the first top frame 101 and is covered, so that it is easily deformed when the edge portion 100c is hit. Therefore, it is possible to reproduce the feeling that the edge portion of the acoustic cymbal is deformed by the impact and absorbs the impact.

  On the other hand, the step 101d and the outer peripheral portion 101e as described above are not formed on the rear half circumference of the first top frame 101, and the radius from the center is shorter than that of the front half circumference. Therefore, in the rear half circumference of the top cymbal pad portion 100, the area where the first top frame 101 does not exist is mainly formed by the elastic body that constitutes the cover 103, as shown in FIG. 1.

  Thus, the rear half circumference of the top cymbal pad portion 100 mainly formed of an elastic body has a hollow portion 103a in the shape of a substantially arc substantially parallel to the outer periphery of the top cymbal pad portion 100 in a top view. Is formed. Inside the hollow portion 103a, a plate-shaped metal weight (weight) 130 having a substantially arc shape in top view that can be included in the hollow portion 103a is disposed. The weight 130 is arranged to balance the weight with members such as the vibration sensor mounting frame 120 mounted on the front side of the top cymbal pad portion 100.

  Further, on the lower surface side of the first top frame 101 (that is, the surface side facing the bottom cymbal pad portion 200), a wall 101f is provided at a position inside the outer periphery of the arm portion 101c. In a substantially circular area surrounded by the wall 101f, signals detected by the vibration sensor mounting frame 120 including the vibration sensor 110 and the vibration sensor 110 and the edge sensor 160 disposed on the top cymbal pad unit 100 are Members related to the musical tone generation of the electronic hi-hat cymbal 1 such as the stereo jack 150 for link output to the bottom cymbal pad unit 200 side are arranged.

  As shown in FIG. 4, the lower surface side of the cover 103 (that is, the surface side facing the bottom cymbal pad portion 200) has a substantially annular shape so as to be substantially parallel to the outer periphery of the top cymbal pad portion 100 when viewed from above. An edge sliding tube 140 is attached. The edge sliding tube 140 is transmitted through the contact portion between the top cymbal pad portion 100 that swings by impact and the top cymbal pad portion 100, and the bottom cymbal that swings when the swing of the top cymbal pad portion 100 is transmitted. In the pad part 200, it is a member for accelerating | sliding with these both pad parts 100 and 200. FIG. The details of the sliding mechanism using the edge sliding tube 140 will be described later.

  The edge sliding tube 140 is made of a material excellent in slipping and wear resistance, in particular, a tube material having a substantially circular width direction cross section (short direction cross section) made of a resin such as nylon or Teflon (registered trademark). It will be. The material of the edge sliding tube 140 is preferably made of nylon from the viewpoint of manufacturing cost.

  Further, since the edge sliding tube 140 is a tube material having a substantially circular cross section in the width direction, the edge sliding tube 140 is in contact with the bottom cymbal pad portion 200 (specifically, an edge sliding film 212 described later). Since the area is suppressed to be small, it is possible to make the slipperiness of each other advantageous in a slip mechanism described later.

  Further, the edge sliding tube 140 is an edge provided on the upper surface 201b of the edge cymbal pad portion 200 on the lower surface side of the top cymbal pad portion 100 when the electronic hi-hat cymbal 1 is in a closed state (closed state). The sliding film 212 is disposed at a position corresponding to approximately the center in the width direction. Therefore, when the top cymbal pad portion 100 and the bottom cymbal pad portion 200 swing back and forth and left and right due to the impact, the distance that the edge sliding tube 140 slides (moves) on the edge sliding film 212 in the sliding mechanism described later is maximized. Can be secured.

  The edge sliding tube 140 is attached to the top cymbal pad portion 100 by providing a substantially annular groove (not shown) concentric with the top cymbal pad portion 100 at a predetermined position on the cover 103 covering the lower surface side. This is done by fitting an annular edge sliding tube 140 into the groove.

  The edge sliding tube 140 is attached in a state where a partial arc protrudes from the surface of the cover 103 in the diametrical section of the top cymbal pad portion 100 (see FIG. 5). Since most of the edge sliding tube 140 is provided so as to be embedded in the cover 103, it is possible to prevent the edge sliding tube 140 from falling off the top cymbal pad portion 100. Note that at least a part of the edge sliding tube 140 may be bonded to the cover 103 with an adhesive.

  The second top frame 102 is a frame made of an elastic material such as rubber, which is softer than the material of the first top frame 101. As shown in FIG. 3, the second top frame 102 includes a head portion 102a protruding upward from the central opening 101a of the first top frame 101, and a shoulder that holds the peripheral edge of the lower surface of the opening 101a from below. Part 102c and arm part 102d for holding a part corresponding to bow part 100b in first top frame 101 from below.

  As shown in FIG. 4, the second top frame 102 protects the case portion 102 e that houses the stereo jack 150 and the wiring extending from the vibration sensor 110, and supplementarily engages the vibration sensor mounting frame 120. An integrated wiring holder 102f is also provided. The second top frame 102 is attached to the first top frame 101 with screws 104.

  In the center of the head portion 102a of the second top frame 102, an insertion hole 102b for allowing the extension rod 420 to pass therethrough is provided. In addition, a wedge shape extends from the bottom surface of the head portion 102a of the second top frame 102 to the periphery of the insertion hole 102b as a groove-like bottom portion in the left-right direction of the top cymbal pad portion 100 (left-right direction in FIG. 4). A recessed portion 102g having a hollow shape is provided. An anti-rotation member 501 described later is loosely fitted in the recess 102g. Due to the shape of both the recess 102g and the rotation stop member 501, the top cymbal pad portion 100 swings but is prevented from rotating when hit. The rotation prevention mechanism of the top cymbal pad unit 100 will be described later.

  The rotation prevention mechanism as described above makes it possible to limit the front side of the top cymbal pad portion 100 as a striking surface. Therefore, the vibration sensor mounting frame 120 for mounting the vibration sensor 110 that detects vibration at the time of striking is: It is not necessary to provide the entire circumference of the top cymbal pad portion 100, and it is sufficient if it is provided in a predetermined region in the front half circumference.

  As shown in FIG. 4, the vibration sensor mounting frame 120 is a plate-like member having an outer periphery along the wall 101 f of the first top frame 101. The vibration sensor mounting frame 120 is provided with a shoulder 101g provided on the front half of the first top frame 101 (upper side in FIG. 4) and spaced apart from the shoulder 101g to such a degree that the vibration sensor mounting frame can be inserted. It is inserted between a plurality of locking portions 101h protruding from the wall 101f. Then, the protrusions 121 arranged in the vibration sensor mounting frame 120 are engaged with the engaging holes (not shown) provided in the engaging portions 101h, thereby engaging the top cymbal pad portion 100. Stopped and attached. On the other hand, the free end side of the vibration sensor mounting frame 120 that is not locked by the protruding portion 121 is not thin and has the ribs 122 erected, and thus has rigidity. The vibration sensor mounting frame 120 mounted on the top cymbal pad portion 100 as described above has a partial section of its outer periphery locked along the wall 101f, and a free end that is the remaining section has a free end. Since it has rigidity, when the top cymbal pad portion 100 is hit, it can vibrate integrally with the first top frame 101.

  The vibration sensor 110 is provided substantially at the center of the surface of the vibration sensor mounting frame 120 on the side facing the first top frame 101. As described above, since the vibration sensor mounting frame 120 is integrated with the first top frame 101 and vibrates, the vibration sensor 110 mounted on the vibration sensor mounting frame 120 is used when the top cymbal pad portion 100 is hit. It is possible to detect vibration with high accuracy. Therefore, the striking force and striking position of the top cymbal pad portion 100 can be detected with high accuracy.

  Further, since the vibration sensor 110 is not directly mounted on the first top frame 101 but is mounted apart from the first top frame 101 via the vibration sensor mounting frame 120, the vibration sensor 110 is not attached to the top frame 101. It is not hit directly when the cymbal pad portion 100 is hit. Therefore, the vibration is made uniform and transmitted wherever the striking surface of the top cymbal pad portion 100 is struck. Therefore, the vibration detection sensitivity when the top cymbal pad portion 100 is hit can be made uniform.

  Furthermore, since the vibration sensor 110 is separated from the first top frame 101 by the vibration sensor mounting frame 120 and is provided at a substantially central portion of the vibration sensor mounting frame 120, the vibration sensor 110 is inserted into the center of the upper cymbal pad portion 100. The distance from the extension rod 420 is moderately separated. Therefore, the sensitivity to the impact and vibration from the extension rod 420 accompanying the opening / closing operation by pedal operation at the time of performance becomes insensitive, so that it is possible to further improve the detection sensitivity of vibration due to hitting of the top cymbal pad portion 100 that is originally required.

  Further, as shown in FIGS. 1 and 4, a pressure-sensitive sensor that detects the hit of the edge portion 100 c on the front half circumference portion of the top cymbal pad portion 100 and above the outer peripheral portion 101 e of the first top frame 101. An edge sensor 160 is arranged. The edge sensor 160 may be attached only to the front half-circumference portion that becomes the striking surface of the top cymbal pad portion 100 by the configuration that prevents the rotation of the top cymbal pad portion 100 as described above. It can be reduced.

  Next, the first fixing means 500 for fixing the top cymbal pad portion 100 and the stand portion 400 will be described. As shown in FIG. 1, the first fixing means 500 is disposed on the upper side of the head portion 102a of the second top frame 102 and the rotation stop member 501 disposed on the lower side of the head portion 102a of the second top frame 102. The clutch top 502 is composed of a clutch screw 503 that is a wing bolt screw, two lock nuts 504, and an upper felt washer 505.

  As described above, the rotation stop member 501 is a member that is loosely fitted in the recess 102g provided in the center portion inside the head 102a. The rotation stop member 501 has a crest (tip portion 501a) having a shape corresponding to the recess 102g, a cylindrical portion having an outer diameter larger than that of the insertion portion 102b, and a pipe portion 501d extending through the center of the tip portion 501a. It is the member which consists of. One end of the pipe portion 501d is inserted from an opening portion 501b provided at a substantially central portion on the tip end portion 501a side of the rotation stopping member 501, and is screwed by a screwing portion (not shown). Furthermore, the pipe part 501d is integrally fixed with respect to the rotation stop member 501 by using the female screw 501c.

  When the pipe portion 501d of the rotation preventing member 501 is inserted into the insertion hole 102b at the substantially center of the top cymbal pad portion 100 and the tip portion 501a is loosely fitted into the recess 102g, the apex portion of the tip portion 501a is the bottom of the recess 102g. Abuts with a trough extending in a groove shape. As a result, the top cymbal pad portion 100 can swing like a balance having the apex portion of the tip end portion 501a as a fulcrum.

  When the pipe portion 501d is inserted into the insertion portion 102b, the pipe portion 501d protrudes from the upper side of the top cymbal pad portion 100. An upper felt washer 505, two lock nuts 504, and a clutch top 502 are arranged in this order from below on a pipe portion 501d protruding from the upper side of the top cymbal pad portion 100. The pipe portion 501d is provided with a screw groove (not shown) in a region in the vicinity of where the two lock nuts 504 are arranged. By screwing the lock nut 504 into the screw groove, the upper felt washer 505 is used. The pressing degree of the top cymbal pad portion 100 can be adjusted. Further, the top cymbal pad portion 100 is pressed against the rotation-preventing member 501 by the lock nut 504 by the lock nut 504 by the lock nut 504, so that the lock nut is also caused by swinging or vibration of the top cymbal pad portion 100 during performance. As a result, the force to press the top cymbal pad portion 100 is unlikely to decrease. In particular, by disposing two lock nuts 504, loosening of the lock nut 504 can be more effectively prevented.

  In this way, the upper felt washer 505 appropriately presses the top cymbal pad portion 100 against the rotation retaining member 501 from the upper surface side, so that the top of the tip portion 501a of the rotation preventing member 501 located on the lower surface side of the top cymbal pad 100 is obtained. The portion is loosely fitted in a moderately close contact with the valley of the recess 102g. In this case, since the extending direction of the crest of the tip 501a and the extending direction of the valley of the recess 102g are limited to the left and right directions of the top cymbal pad portion 100, the top cymbal pad portion 100 is, for example, hitting the front side In addition, as described above, it swings in one direction, like a balance, but the top cymbal pad portion 100 is prevented from rotating around the rotating member 501.

  The clutch top 502 disposed on the upper side of the lock nut 504 is fixed to the end portion of the pipe portion 501d by a clutch bolt 502a. The upper end of the pipe portion 501d is provided on the upper portion of the clutch top 502. The clutch screw 503 is disposed below a screw hole (not shown) for screwing.

  As described above, after the first fixing means 500 is attached to the top cymbal pad portion 100, the extension rod 420 is inserted into the pipe portion 501d from below the top cymbal pad portion 100. Next, the top cymbal pad portion 100 is fixed on the extension rod 420 so as not to rotate around its axis by tightening the clutch screw 503 after arranging the top cymbal pad portion 100 at an appropriate height. The

  Therefore, when the top cymbal pad portion 100 is installed on the extension rod 420 by the first fixing means 500 configured as described above, the top cymbal pad portion 100 is rotated around the axis of the extension rod 420 or rotated at the time of impact. It swings around the fastening member 501 without rotating.

  Further, since the extension rod 420 is inserted into the pipe portion 501d, the vibration of the extension rod 420 or the like is not directly transmitted to the top cymbal pad portion 100, so the vibration sensor 110 detects the vibration of the extension rod 420 as noise. Can be reduced.

  Next, the structure of the bottom cymbal pad portion 200 will be described with reference to FIGS. 1 to 3 and FIGS. 6 and 7. FIG. 6 is a front view of the top surface side of the bottom cymbal pad portion 200, and FIG. 7 is a view in which the bottom cymbal pad portion 200 is separated from the second fixing means 600. In the present embodiment, “the upper surface of the bottom cymbal pad portion 200” and “the lower surface of the bottom cymbal pad portion 200” indicate the upper surface and the lower surface in a state where they are attached to the stand portion 400, respectively. Are also used in the same meaning.

  As shown in FIG. 1, the bottom cymbal pad portion 200 includes a first bottom frame 201, a second bottom frame 202 provided adjacent to the upper surface side central portion of the first bottom frame 201, and a top cymbal pad portion. The stereo jack 250 for inputting the signals of the vibration sensor 110 and the edge sensor 160 that are output from the 100 stereo jacks 150 and transmitted via the plug 151, the cable 152, and the plug 251, and the input from the stereo jack 250 An output jack 240 and the like are provided for outputting the signals of the sensors, the signals detected by the close switch 220 provided on the bottom cymbal pad unit 200, and the signals from the displacement sensor 610 to the outside. 2 and 10, the cable 152 is not shown in order to simplify the drawing.

  The first bottom frame 201 is made of hard plastic (ABS resin, polycarbonate resin, or the like). Like the top cymbal pad portion 100, the first bottom frame 201 has a substantially circular shape when viewed from the upper surface side or the lower surface side. It has a dish-like shape that rises like a dome.

  An opening 201 a is provided at the center of the first bottom frame 201. The opening 201 a is formed in a substantially circular shape having two grooves corresponding to the two grooves 202 b provided in the second bottom frame 202.

  As shown in FIG.1 and FIG.5, the edge part upper surface 201b of the 1st bottom frame 201 has an annular recessed part along the circumference | surroundings, and metal plates, such as an iron plate and an aluminum plate, on the bottom face of the recessed part 210 is fixed to the first bottom frame 201 by screws 213 as shown in FIG. Although not particularly illustrated, an appropriate number (for example, about 10) of the screws 213 are equally arranged around the metal plate 210 arranged in an annular shape on the first bottom frame 201. .

  A cushion sheet material 211 made of a material having elasticity such as rubber is laminated on the upper side of the metal plate 210, and an edge sliding film 212 is further laminated on the upper side of the cushion sheet material 211. Here, the edge slip film 212 is disposed so as to be a flat surface that is substantially integral with the edge portion upper surface 201b. Further, the laminated portion of the cushion material 211 and the edge sliding film 212 protects a wiring (not shown) extending from a close switch 220 described later to the output jack 240 housed in the second bottom frame 202. Furthermore, it extends so as to cover the two wiring holders 201c through which this wiring passes.

  The edge sliding film 212 is a member for smoothly swinging the top cymbal pad portion 100 and the bottom cymbal pad portion 200 when the top cymbal pad portion 100 and the bottom cymbal pad portion 200 swing while being in contact with each other. It is. The edge slip film 212 is made of a material having good slipperiness and moderate strength, for example, a resin such as polyester or Teflon (registered trademark). Therefore, when the top cymbal pad portion 100 is hit, the edge sliding tube 140 provided on the top cymbal pad portion 100 can smoothly slide on the edge sliding film 212, and as a result, the top cymbal pad portion 100. And the bottom cymbal pad portion 200 swing smoothly while being in contact with each other. A slip mechanism composed of the edge slip film 212 and the edge slip tube 140 will be described later.

  Further, between the metal plate 210 and the cushion material 211, one close switch 220, which is a film-like pressure sensor, is provided in the left-right direction of the bottom cymbal pad portion 200 as shown in FIGS. Is provided. In FIG. 7, the cushion sheet material 211 and the edge slip film 212 that cover the close switch 200 in the peripheral region including one of the close switches 220 (the close switch 220 disposed on the left side of the bottom cymbal pad portion 200). Are partially omitted and the close switch 220 is exposed. In the cross-sectional view of FIG. 3, the close switch 220 should be illustrated between the metal plate 210 and the cushion sheet material 211, but the illustration thereof is omitted to prevent complication of the drawing.

  The close switch 220 is a film-like pressure sensor having a multilayer structure, and is a sensor that detects a closed state (closed state) of the electronic hi-hat cymbal 1. As shown in FIG. 3, when the top cymbal pad portion 100 and the bottom cymbal pad portion 200 are brought into contact with each other by the depression of a pedal (not shown) provided below the stand portion 400 and are brought into a closed state (closed state). In addition, the close switch 220 detects a pressure applied by the edge slip tube 140 provided in the top cymbal pad portion 100, and a signal generated by the detection is transmitted to the output jack 240 via a wiring (not shown). .

  The close switch 220 is pressed by the edge sliding tube 140 of the top cymbal pad portion 100. At this time, the close switch 220 is pressed against the metal plate 210, so that the detection sensitivity of the press is good. To do.

  Further, since the close switch 220 is pressed through the elastic cushion material 211, the pressing force by the edge sliding tube 140 is appropriately dispersed and transmitted to the close switch 220. Therefore, this structure can improve the detection sensitivity of the close switch 220.

  When the top cymbal pad portion 100 is struck, the top cymbal pad portion 100 swings, so that the close switch 220 on either side can often be pressed, so that the closed state (closed state) is detected. Thus, as described above, it is effective to provide a pair of close switches 220 in the left-right direction of the bottom cymbal pad portion 200 and detect whether or not these close switches 220 are pressed simultaneously. That is, even when the striking surface (front side) of the top cymbal pad portion 100 is struck in the closed state (closed state), the pressing force by the edge sliding tube 140 compares the influence of the swing in the center in the front-rear direction due to the striking. Therefore, the closed state (closed state) can be reliably detected.

  Here, the close switch 220 will be described with reference to FIG. FIG. 8 is a diagram for explaining the structure of the close switch 220. FIG. 8A is a partially exploded view of the close switch 220, and FIG. 8B is a view of a cross section taken along the line CC in FIG. 8A from the cross-sectional direction. .

  The close switch 220 is a laminated body including three layers of a first base film 221, a spacer film 222 r, and a second base film 223. Specifically, as shown in FIG. 8A, the first base film 221 that is a layer adjacent to the cushion sheet material 211 and the second base film 223 that is a layer adjacent to the metal plate 210. And a spacer film 222 disposed between these films 221 and 223. In the exploded view of FIG. 8 (a), the first base film 221 is shown on the upper side of the drawing, while the second base film 223 and the upper side (first base film) are shown on the lower side of the drawing. The portion composed of the spacer film 222 laminated on the (221 side) is shown.

  The first base film 221 is an insulating resin thin film, and a first conductive pattern 221a is printed on one surface thereof. In addition, the 1st conductive pattern 221a in Fig.8 (a) shows the area | region where the conductive pattern is printed, and it is not the summary of this invention about the detailed wiring pattern of the 1st conductive pattern 221a. Therefore, it is not illustrated and the description thereof is omitted.

  The second base film 223 is an insulating resin thin film, and a second conductive pattern 223a is printed on one surface thereof. In addition, the 1st conductive pattern 223a in FIG. 8A shows the area | region where the conductive pattern is printed by the area | region of hatching (a part and the part hidden by the spacer film are dotted lines), Since the detailed wiring pattern of the conductive pattern 223a is not the gist of the present invention, it is not shown and description thereof is omitted.

  In the close switch 220, the first conductive pattern 221a of the first base film 221 and the second conductive pattern 223a of the second base film 223 are provided to face each other, and the first conductive pattern 221a When the second conductive pattern 223a comes into contact, a current is conducted, and the switch ON is detected by the current.

  The spacer film 222 is an insulating resin thin film, and corresponds to the space between the first conductive pattern 221a and the second conductive pattern 223a in the close switch 220 as shown in FIG. 8A. The part is provided with a plurality of through-holes 222a continuously provided in the longitudinal direction.

  The plurality of through holes 222a expose the first conductive pattern 221a and the second conductive pattern 223a to each other, but remain between the adjacent through holes 222a as shown in FIG. 8B. The first conductive pattern 221a and the second conductive pattern 223a are separated by the spacer film 222 when left standing. As a result, when the top cymbal pad portion 100 and the bottom cymbal pad portion 200 are in the open state (open state), the first conductive pattern 221a and the second conductive pattern 223a are separated from each other. Does not flow. On the other hand, as a result of the top cymbal pad portion 100 and the bottom cymbal pad portion 200 being in a closed state (closed state) and the edge sliding tube 140 abutting or pressing the edge sliding film 212, the first base film is pressed by the pressing. 221 bends, the first conductive pattern 221a and the second conductive pattern 223a come into contact with each other, and a current is conducted.

  Further, by providing a plurality of through holes 222a in the spacer film 222, as shown in FIGS. 8A and 8B, the first conductive pattern 221a and the second conductive pattern 223a are separated from each other. A plurality of spacer portions to be supported are formed. Therefore, the first conductive pattern 221a and the second conductive pattern 223a are brought into contact with each other due to bending due to deterioration of the cushion sheet material 211 that may be caused by aging, and as a result, the close switch 220 is prevented from malfunctioning. Can do.

  Positioning holes 220a penetrating the first base film 221, the spacer film 222, and the second base film 223 are provided at both ends of the close switch 220 in the longitudinal direction. The positioning hole 220a is provided at a predetermined position of the first bottom frame 201 and is engaged with a positioning protrusion (not shown) penetrating the metal plate 210, so that the close switch 220 is disposed at the predetermined position. . The close switch 220 positioned based on the positioning hole 220a is fixed on the metal plate 210 with a double-sided tape or an adhesive.

  The structure of the bottom cymbal pad portion 200 will be described with reference to FIGS. 1 to 3 and FIGS. 6 and 7 again. The second bottom frame 202 is a frame made of a soft material, for example, an elastic body such as rubber. As shown in FIG. 3, the second bottom frame 202 includes an opening 202a having a shape along the inner peripheral side of the opening 201a of the first bottom frame 201 and an inner side of the dome 201d of the first bottom frame 201 (see FIG. 3 is provided with a recess 202c having a bottom surface shaped along the upper surface of the paper surface in FIG. 3, and for accommodating two output jacks 240 in the left-right direction of the bottom cymbal pad portion 200, as shown in FIG. And a case portion 202e for receiving a stereo jack 250 for inputting a signal from the top cymbal pad portion 100 in the rearward direction. As shown in FIGS. 1 and 6, the second bottom frame 202 is fixed to the first bottom frame 201 with screws 204.

  As described above, the opening 202a has a circular shape along the inner peripheral side of the opening 201a of the first bottom frame 201, and as shown in FIG. Opening in a substantially circular shape having 202b. A convex portion 601b of a bottom anchor 601 fixed so as not to rotate about the axis of the hollow shaft 410 of the stand portion 400 is fitted into the opening 202a from below. On the other hand, the convex portion 611a of the displacement sensor 610 is fitted from above the opening 202a. At that time, when the projection 611d provided on the projection 611b of the displacement sensor 610 is inserted into the locking hole 601e provided on the projection 601b of the bottom anchor 601, the projection 601b and the projection 611a are opened. It is connected on the inner peripheral side of the portion 202a.

  Since both the convex portion 601b and the convex portion 611a have substantially the same shape as the opening portion 202a having a groove portion 202b protruding from the periphery, as described later, the bottom cymbal pad portion 200 is The bottom anchor 601 that is non-rotatably fixed around the axis of the stand unit 400 and the displacement sensor 610 cannot be rotated. Therefore, even when the bottom cymbal pad portion 200 swings due to the swing of the top cymbal pad portion 100 due to the shape of the opening 202a, the convex portion 601b, and the convex portion 611a, the stand portion 400 Rotation around the axis is prohibited. Accordingly, since the sensors arranged on the bottom cymbal pad portion 200 can be arranged at limited positions, the arrangement of the pair of close switches 220 as in the present embodiment is the most preferable position of the bottom cymbal pad portion 200. Can be limited to the left and right direction.

  As shown in FIG. 7, the recess 202c is provided with two protrusions 202f around the opening 202a excluding the groove 202b provided in the diameter direction corresponding to the front and rear direction of the bottom cymbal pad portion 200. Yes. Each of the protrusions 202f has a shape in which the approximate center thereof is the top and is inclined downward from the top toward both ends. That is, the protrusion 202f is formed such that a portion corresponding to the left and right direction of the bottom cymbal pad portion 200 is raised. As a result, as will be described later, the bottom cymbal pad portion 200 can be fixed to be swingable back and forth by the second fixing means 600.

  Further, the two output jacks 240 are arranged so that the respective opening portions 240a face the left-right direction of the bottom cymbal pad portion 200 and are exposed to the outside of the first bottom frame 201 as shown in FIG. Yes. Since the openings 240a of the two output jacks 240 are directed in the left-right direction, the wiring cords connected to these output jacks 240a are not easily entangled, and the plugs of the wiring cords fall off from the output jack 240a. Can be prevented. Further, since the bottom cymbal pad portion 200 is restricted to swing in the front-rear direction as described above, the wiring cord connected to the output jack 240 with the opening 240a facing in the left-right direction is affected by the swing. As a result, it is difficult for the plug of the wiring cord to fall off the output jack 240.

  Next, the second fixing means 600 that fixes the bottom cymbal pad part 200 and the stand part 400 will be described with reference to FIGS. 7 and 9 to 10. FIG. 9 is a diagram for explaining the second fixing means 600, and FIG. 10 is a partially enlarged sectional view in which a portion of the second fixing means 600 in the sectional view of FIG. 3 is enlarged.

  As shown in FIG. 7, the second fixing means 600 includes a bottom anchor 601 that supports the first bottom frame 201 from below, a displacement sensor 610 that presses the first bottom frame 201 against the bottom anchor 601 from above, and a bottom anchor. The clamp unit 620 fixes the 601 to the stand unit 400.

  The bottom anchor 601 includes an opening 601a formed at the center, two protrusions 601b that fit into the grooves 202b of the second bottom frame 202, a locking hole 601e formed in the protrusion 601b, and the protrusions. It is a metal part such as an aluminum die casting having a recess 601c formed on the opposite side of the surface on which 601b is formed and a hook portion 601d formed on the side surface. An elastic sheet such as a rubber sheet is disposed on the bottom anchor 601 as a cushion material 602 for the bottom cymbal pad portion 200.

  The displacement sensor 610 is a sensor for detecting the amount of displacement of the top cymbal pad portion 100, and the sensor structure will be described later. The lower side (bottom surface) of the outer periphery of the case portion 611 of the displacement sensor 610 is a substantially flat surface, and a convex portion 611a is provided on the substantially flat surface. The protrusion 611a has a shape that fits into the opening 202a having the groove 202b in the second bottom frame, and has a protrusion 611d (see FIG. 1) for insertion into the locking hole 601e of the bottom anchor 601. is doing. Further, the convex portion 611a is provided with an opening 611c which is a part of a through-hole penetrating the displacement sensor 610 up and down.

  Furthermore, as shown in FIG. 10, the displacement sensor 610 is provided with a sleeve 612 disposed so as to vertically penetrate the center of the displacement sensor 610, and the screw portion 612 a projects downward from the displacement sensor 610. ing.

  As shown in FIG. 7, the bottom cymbal pad portion 200 is disposed between the bottom anchor 601 and the displacement sensor 610, and the shape of the convex portion 601 b of the bottom anchor 601 and the convex portion 611 a of the displacement sensor 610 is changed to that of the bottom cymbal pad 200. After matching the shape of the opening 202a having the groove 202b, the protrusion 611b of the displacement sensor 610 is fitted into the locking hole 601e on the bottom anchor 601 side. Then, the nut 605 is screwed into the screw portion 612a that passes through the bottom cymbal pad portion 200 and the bottom anchor 601 from the displacement sensor 610, and thereby the bottom cymbal pad portion 200 is inserted into the recess 601c of the bottom anchor 601. It is fixed to the second fixing means 600.

  In the second fixing means 600, the shape of the convex portion 601b of the bottom anchor 601 and the shape of the convex portion 611a of the displacement sensor 610 are fitted to the shape of the opening 202a having the two groove portions 202b. 200 is fixed around the second fixing means 600 in a non-rotatable manner.

  As described above, the two protrusions 202f provided on the second bottom frame 202 of the bottom cymbal pad portion 200 have a high portion corresponding to the left or right direction of the bottom cymbal pad portion 200, respectively. It is formed so as to incline downward toward both ends of the portion 202f. Therefore, the bottom cymbal pad portion 200 is restricted from swinging in the front-rear direction along the shape while contacting the outer peripheral bottom surface of the case portion 611 of the displacement sensor 610. Therefore, the bottom cymbal pad portion 200 is fixed to the stand portion 400 so as to be swingable only in the front-rear direction by the fixing manner by the second fixing means 600 as described above.

  As described above, since the swinging direction of the bottom cymbal pad portion 200 is regulated in the front-rear direction, the pair of close switches 220 arranged in the left-right direction of the bottom cymbal pad portion 200 as in the present embodiment is caused by hitting. The closed state (closed state) can be detected with high accuracy without being affected by the oscillation of the center in the front-rear direction.

  The displacement sensor 610 not only functions as a sensor described later, but also functions as a part of the second fixing means 600 by the case portion 611. Therefore, the number of parts of the electronic hi-hat cymbal 1 can be reduced, and thereby the manufacturing cost can be reduced.

  When the bottom cymbal pad part 200 is disposed between the bottom anchor 601 and the displacement sensor 610, the bottom anchor 601 is fixed to the stand part 400 by the clamp part 620 as shown in FIG. The clamp unit 620 includes a clamp 621 and an arm 622 made of an elastic body such as an elastomer, a clamp holder 623, and a screw 624 that holds the free end of the clamp holder 623.

  The clamp portion 620 sandwiches the hollow shaft 410 by the clamp 621, further sandwiches it from the outside by the clamp holder 623, and fastens both free ends of the clamp holder 623 with screws 624, so that the clamp portion 620 is placed on the hollow shaft 410. Fixed non-rotatable.

  On the other hand, the bottom anchor 601 on which the bottom cymbal pad portion 200 is placed is disposed on the lower felt washer 412 that is a felt washer, and the arm 622 is fitted to the hook portion 601d provided on the side surface of the bottom anchor 601. The mating part 622a is fitted. Since the fitting portion 622a has a diameter slightly larger than the diameter of the main body portion of the clamp 620 and the inner diameter of the hook portion 601d, the fitting portion 622a, which is an elastic body, is deformed by pressing and becomes a hook portion 601d. Mated. Therefore, the fitting part 622a is difficult to drop off from the hook part 601d.

  In addition, the clamp portion 620 is flexible because it is made of an elastic material as described above, and even if the shape of the felt holding portion 411 that holds the lower felt washer 412 in various commercially available stands varies, Since 622 curves appropriately according to its shape, it can be attached. Therefore, the bottom cymbal pad unit 200 can be installed on the commercially available stand unit 400.

  Next, the structure of the sensor portion of the displacement sensor 610 that is a part of the second fixing means 600 will be described. As shown in FIG. 10, the displacement sensor 610 includes a case portion 611 that is a hollow cylinder having an open top surface, a circular sensor sheet 613 that is housed in the bottom inside the case portion 611, and the sensor sheet 613. A hard substrate 614 that is substantially the same shape as the sensor sheet 613 disposed below, a conical coil spring 615 that is disposed on the sensor sheet 613 and extends in a direction from the top cymbal pad portion 100 toward the bottom cymbal pad portion 200; It is comprised from the cover part 616 which has an upward convex shape which contacts the upper part of the coil spring 615. As shown in FIG.

  In addition, an opening 611 c is provided at the center of the case 611, and this opening 611 c is a part of a through-hole that passes through the top and bottom of the displacement sensor 610. Although not particularly illustrated, an opening serving as a part of the through hole is also provided at the center of each member of the sensor sheet 613, the hard substrate 614, and the lid 616. A sleeve 612 for inserting the extension rod 420 is inserted through each opening including the opening 611 c and the center of the coil spring 615.

  Since the extension rod 420 is inserted through a sleeve 612 that passes through the inside of the displacement sensor 610, the deflection of the extension rod 420 is not directly transmitted to the displacement sensor 610. With such a structure, when the displacement sensor 610 detects the displacement amount of the top cymbal pad portion 100 as described later, the displacement amount can be detected with high accuracy without being affected by the bending of the extension rod 420.

  In this displacement sensor 610, when a pedal (not shown) is depressed, the extension rod 420 is lowered, and the space between the top cymbal pad portion 100 and the bottom cymbal pad portion 200 is in an open state (open state) according to the amount of depression. The state shifts from the state shown in FIG. 1 to the closed state (closed state) (the state shown in FIG. 2). Since the top cymbal pad portion 100 is fixed to the extension rod 420 by the first fixing means 500, when the extension rod 420 is lowered by stepping on the pedal, the rotation stopping member 501 is also lowered together. When the rotation stop member 501 is lowered, the lid 616 is pushed down by the lower side of the rotation stop member 501. Thereby, the coil spring 615 is pressed against the sensor sheet 613 and the hard substrate 614 and compressed, and is deformed in the vertical direction by the compression force.

  In this way, the deformation caused by the compression of the coil spring 615 in the vertical direction is electrically detected using the sensor sheet 613, and output to an external processing device via a wiring (not shown) via the output jack 240. The amount of vertical displacement of the extension rod 420 due to depression of the pedal, that is, the amount of displacement of the top cymbal pad portion 100 due to depression of the pedal is detected.

  Here, the sensor portion of the displacement sensor 610 will be described with reference to FIG. FIG. 11 is an exploded view of the sensor portion of the displacement sensor 610 in the direction in which the extension rod 420 is inserted. The “sensor portion of the displacement sensor 610” means a portion constituted by the coil spring 61, the sensor sheet 613, and the hard substrate 614.

  The sensor sheet 613 is a laminated body as shown in FIG. 11, and in order from the side adjacent to the coil spring 615, a pressing film 613a, a base film 613b, a conductive printing portion 613c printed on the base film 613b, and a base A carbon printing portion 613d printed on the film 613b and a spacer film 613e are disposed.

  The pressing film 613a is a thin film made of a plastic film such as polyester, and has a substantially annular outer peripheral portion 613a1 having an outer diameter substantially the same as the wide mouth portion 615a of the coil spring 615 and a width on which the wide mouth portion 615a can be placed. , Two elongated pressing portions 613a2 that traverse in the diameter direction, and an annular inner peripheral portion 613a3 having an inner diameter through which the sleeve 612 can be inserted.

  The base film 613b is an insulating resin thin film, and an annular conductive printing portion 613c is printed on a surface opposite to the surface facing the pressing film 613a so as to cover the conductive printing portion 613c. A carbon printing portion 613d is printed on the surface. The carbon printing part 613d has an annular ring part 613d2 that covers the conductive printing part 613c, and two elongated resistor parts 613d1 that protrude outward in the diameter direction of the annular part 613d2. In the sensor sheet 613, the resistance portion 613d1 is disposed at a position where it can be pressed by the pressing portion 613a2.

  The spacer film 613e is an insulating resin thin film, and has a through hole 613e2 having an inner diameter through which the sleeve 612 can be inserted, and two penetrations that expose the vicinity of the position corresponding to the resistance portion 613d1 in the sensor sheet 613. And a hole 613e1. Moreover, the width | variety remaining in the outer peripheral part of the spacer film 613 by formation of the through-hole 613e1 has a width | variety which can mount the wide opening part 615a.

  The hard substrate 614 is a thin plate substrate made of a glass base epoxy laminated plate or the like, and can contact the resistance portion 613d1 on the surface facing the sensor sheet 613 and the through hole 614c through which the sleeve 612 can be inserted. Two elongated conductive patterns 614a provided at a position and a drawer provided on a surface opposite to the surface facing the sensor sheet 613 and connected to the conductive pattern 614a through a through hole (not shown) Pattern 614b. Note that each of the conductive pattern 614a and the lead pattern 614b is a conductive pattern formed of a metal such as a copper foil.

  In the sensor part of the displacement sensor 610, the resistance part 613d1 and the conductive pattern 614a are exposed to each other through the through hole 613e2 of the spacer film 613e. Therefore, at the time of standing, resistance part 613d1 and conductive pattern 614a do not contact, and an electric current is not conducted.

  On the other hand, when the coil spring 615 is pressed from the top to the wide-mouthed portion 615a by the lowering of the rotation stop member 501 due to depression of a pedal (not shown), the coil spring 615 is compressed and a wire rod of the coil spring 615 (described later). The wire 615b) presses the pressing portion 613a2 of the pressing film 613a. The pressing force is transmitted to the resistance portion 613d1, and as a result, the contact is made with the conductive pattern 614a of the hard substrate 614, and current is conducted through the lead pattern 614b.

  Next, an outline of detection of the displacement amount of the top cymbal pad unit 100 by the sensor unit of the displacement sensor 615 will be described with reference to FIG. FIG. 12 is a diagram for schematically explaining the detection of the displacement amount of the top cymbal pad portion 100 by the displacement sensor 610, in the order of FIG. 12A → FIG. 12B → FIG. 12C. 615 shows a case where the pressing force accompanying the displacement due to the lowering of the top cymbal pad portion 100 is increased. 12 shows a case where each member is cut at a position corresponding to the DD line shown on the pressing film 613a in FIG. 11 in a state where the sensor portion of the displacement sensor 610 shown in FIG. 11 is assembled. It is sectional drawing. In FIG. 12, for the sake of simplification, layers other than the spacer film 613e in the sensor sheet 613, that is, the pressing film 613a and the base film 613b, and the conductive printing portion 613c and the carbon printed on the base film 613b are illustrated. The printing unit 613d is collectively shown as a sensor layer 613A.

  When the coil spring 615 is not pressed, the wire of the wide-mouthed portion 615a of the coil spring 615 is only placed on the outer peripheral portion of the spacer film 613. Therefore, the resistance portion 613d1 included in the sensor layer 613A and the conductivity of the hard substrate 614 No contact is made with the pattern 614a, and no current is conducted.

  As shown in FIG. 12A, when the coil spring 615 is slightly pressed by the lowering of the top cymbal pad portion 100, the coil spring 615 is compressed and deformed, and the wire 615b other than the wide-mouthed portion 615a in the coil spring 615 moves the sensor layer 613A. When pressed, the pressure is transmitted to the pressing portion 613a2 and the resistance portion 613d1 of the pressing film 613a, and as a result, the resistance portion 613d1 and the conductive pattern 614a come into contact with each other, and the current is conducted.

  FIG. 12B shows a state in which the top cymbal pad portion 100 is further lowered from the state shown in FIG. 12A and the coil spring 615 is further compressed and deformed, and more wire rods than in FIG. 615b presses the sensor layer 613A. As a result, the contact position between the resistance portion 613d1 that is carbon printing and the conductive pattern 614a changes. Therefore, the electrical resistance value between the contact positions is smaller than in the case of FIG.

  FIG. 12C is a view showing a case where the top cymbal pad portion 100 is further lowered from the state shown in FIG. 12B. The coil spring 615 is further compressed and deformed, and more than FIG. 12B. The wire 615b presses the sensor layer 613A. As a result, the distance between the contact positions of the resistance portion 613d1 and the conductive pattern 614a, which are carbon printing, is smaller than in the case of FIG. Therefore, the electrical resistance value between the contact positions is smaller than in the case of FIG.

  That is, as the top cymbal pad portion 100 descends, the contact position between the resistance portion 613d1 that is carbon printing and the conductive pattern 614a changes, so the distance between the contact positions changes. Therefore, by detecting the electrical resistance value between the contact positions, the vertical displacement amount of the top cymbal pad portion 100 can be detected.

  Since the pressing portion 613a2 that transmits the compression deformation due to the pressing of the coil spring 615 to the resistance portion 613d1 is formed to be elongated, the pressing amount applied to the coil spring 615 can be transmitted to the resistance portion 613d1 in a concentrated manner. Therefore, it is possible to detect a change in electrical resistance value with a change in the amount of pressing applied to the coil spring 615 with high accuracy.

  Next, in the electronic hi-hat cymbal 1 of the present invention, a case where the top cymbal pad portion 100 and the bottom cymbal pad portion 200 are link-connected will be described. FIG. 13 is a rear view of the electronic hi-hat cymbal 1 of the present invention. An L-shaped plug 151, which is one end of a flexible cable 152, is inserted into an opening (not shown) of the stereo jack 150 provided on the rear side of the case portion 102 e of the top cymbal pad portion 100. On the other hand, an L-shaped plug 252 provided at the other end of the cable 152 is an opening (not shown) of the stereo jack 250 provided on the rear side of the case portion 202e of the bottom cymbal pad portion 200. Is inserted.

  As shown in FIG. 13, since both the opening portions of the stereo jack 150 and the stereo jack 250 face the rear side, the cable 152 can be as short as possible and wired in a space-saving manner. In addition, when both the opening portions of the stereo jack 150 and the stereo jack 250 are on the rear side, space saving in the closed state (closed state) of the electronic hi-hat cymbal 1 can be achieved. On the other hand, both the opening portions of the stereo jack 150 and the stereo jack 250 can be provided on the right side or the left side. In this case, the swing of the top cymbal pad portion 100 and the bottom cymbal pad portion 200 is both in the front-rear direction. Therefore, the plug 151 and the plug 251 are difficult to drop off.

  Further, since the plug 151 and the plug 252 are both L-shaped plugs, even if the cable repeats extending or bending according to the vertical movement of the top cymbal pad portion 100, the stereo jack In the openings of 150 and the stereo jack 250, the fitting portions of the plug 151 and the plug 252 can be freely rotated around the major axis as appropriate. Therefore, the plug 151 and the plug 252 can be prevented from being pulled out from the stereo jack 150 and the stereo jack 250, and the load on the plug 151 and the plug 252 can be reduced, and the plug can be prevented from being damaged.

  Next, a sliding mechanism between the top cymbal pad portion 100 and the bottom cymbal pad portion 200 in the electronic hi-hat cymbal 1 of the present invention will be described with reference to FIG. FIG. 14 is a cross-sectional view of the electronic hi-hat cymbal 1 of the present invention that is tilted forward when it is struck in the closed state (closed state), cut along the same cutting line as in FIG. For ease of explanation, only the case of the closed state (closed state) will be described.

  As described above, the top cymbal pad portion 100 is fixed to be swingable in the front-rear direction by the first fixing means 500, while the bottom cymbal pad portion 200 is fixed in the front-rear direction by the second fixing means. It is fixed so that it can swing. Therefore, when the upper side of the top cymbal pad portion 100 is hit, the top cymbal pad portion 100 swings in the front-rear direction, and the swing of the top cymbal pad portion 100 is transmitted to the bottom cymbal pad portion 200, and the bottom cymbal pad The part 200 also starts to swing in the front-rear direction.

  Since the edge sliding tube 140 and the edge sliding film 212 made of a material having sliding properties are provided at the contact portions between the top cymbal pad portion 100 and the bottom cymbal pad portion 200, respectively, The edge sliding tube 140 slides smoothly. As a result, the top cymbal portion 100 and the bottom cymbal pad portion 200 swing smoothly, and as a result, the feel of hitting becomes a natural feel similar to an acoustic hi-hat cymbal.

  Further, as shown in FIG. 14, when the top cymbal pad portion 100 and the bottom cymbal pad portion 200 are inclined forward, the edge slip tube 140 reaches the end of the left side of the paper surface on the edge slip film 212. Yes. Although not shown, in a state where the top cymbal pad portion 100 and the bottom cymbal pad portion 200 are inclined rearward, the edge slip tube 140 reaches the end on the right side of the paper surface on the edge slip film 212. That is, when swinging in the front-rear direction, the edge slip tube 140 moves from end to end of the edge slip film 212. Therefore, by forming the edge slip film 212 wide in an appropriate range, it is possible to sufficiently secure a region where the edge slip film 212 can slide with the edge slip tube 140 at the time of swinging.

  As described above, according to the electronic hi-hat cymbal 1 of the present invention, since both the top cymbal pad portion 100 and the bottom cymbal pad portion 200 are fixed so as to be swingable, a performance feeling close to that of an acoustic hi-hat cymbal is obtained. be able to.

  In addition, since the top cymbal pad unit 100 and the bottom cymbal pad unit 200 are provided with the edge sliding tube 140 and the edge sliding film 212, respectively, The rocking while the bottom cymbal pad portion 200 is in contact is as smooth as the acoustic hi-hat cymbal. Therefore, a natural feel similar to an acoustic hi-hat cymbal can be obtained.

  Furthermore, neither the top cymbal pad part 100 nor the bottom cymbal pad part 200 rotates around the axis of the stand part 400 and the extension rod 420, and the swinging direction is restricted in the front-rear direction. Convenient for placement of cables and cables.

  The present invention has been described above based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications and changes can be easily made without departing from the spirit of the present invention. Can be inferred.

  For example, in the above embodiment, the edge sliding tube 140 is arranged in a ring around the top cymbal pad portion 100. However, instead of this, a projecting sliding member may be provided. Good.
