Description

  The present invention relates to an electronic percussion instrument.

  In recent years, electronic percussion instruments simulating percussion instruments such as acoustic cymbals have been widely used.

  In percussion instruments such as acoustic cymbals, a musical sound is generated by vibrating the striking surface by striking the striking surface and the perimeter of the striking surface, whereas electronic percussion instruments have a percussion sensor on the percussion surface and a sheet sensor on the perimeter of the striking surface. By striking the striking surface and the perimeter of the striking surface of the electronic pad equipped with the above, sound generation is performed based on the vibration and pressure detected by these sensors.

  In addition, the silencing operation is performed by pinching the periphery of the striking surface with a finger, similar to the silencing operation in an acoustic cymbal or the like. In the case of acoustic cymbals, the silencing operation of pinching the perimeter of the striking surface with a finger stops the vibration of the striking surface that is the source of sound generation. It is recognized that the silencing operation is being performed by continuing to apply pressure to the sheet sensor for a certain period of time.

  As described above, in the case of the conventional electronic percussion instrument, even if the player detects the pressure by the sheet sensor provided at the perimeter of the striking surface by picking the perimeter of the striking surface with a finger in order to mute the sound being generated. In the seat sensor, the pressure is also detected by striking the perimeter of the striking surface. Therefore, in order to determine whether the pressure is due to the silencing operation or striking the perimeter of the striking surface, the pressure is above a certain level. It is necessary to determine whether or not to continue for a period of time, which causes a problem that actual mute for the mute operation is delayed.

  In view of the above circumstances, an object of the present invention is to provide an electronic pad that can suppress an actual silencing delay with respect to a silencing operation.

  The electronic pad of the present invention that achieves the above object is an electronic pad that receives an impact on the upper surface and detects and outputs the impact, a disc-shaped first frame, and a cover that covers the upper surface of the first frame; A striking sensor that detects striking transmitted to the first frame through the cover, and an operation sensor that is disposed on the lower surface of the peripheral portion of the first frame and detects an operation on the peripheral portion. It is characterized by that.

  The electronic pad according to the present invention is provided with an operation sensor that detects only the operation of the player's batting and operation on the lower surface of the peripheral edge that is hardly hit in normal performance. Operation can be linked to mute in an instant.

  Here, the electronic pad of the present invention supports the first frame from below and has a mounting hole penetrating vertically in the center, and a pole of a stand having a pole supporting the electronic pad is installed in the mounting hole. It is preferable that a second frame made of a soft material is provided as compared with the first frame, which is inserted and supported by the pole.

  As described above, the first frame is supported by the second frame made of a softer material than the first frame from below, and the second frame is fixed to the pole of the stand, so that the first frame becomes the stand. The vibration generated in the first frame is smoothly propagated without being fixed to the frame. For this reason, the impact sensor provided in the first frame can accurately detect vibration caused by impact.

  Further, in the electronic pad according to the present invention, the second frame has a concave portion of a wedge shape extending in a predetermined direction around the attachment hole on the lower surface of the second frame, and the concave portion. Has an insertion hole in the center and has an upper surface protruding into a wedge shape with a peak extending in a predetermined direction. The pole is inserted into the insertion hole and is fitted or loosely fitted to a rotation stop member fixed to the pole. It is preferable that

  The second frame has a recess that fits or loosely fits with an anti-rotation member fixed to the pole around an attachment hole on the lower surface thereof, and is supported by the pole of the stand with the anti-rotation member interposed therebetween. Therefore, the rotation of the electronic pad with the pole as the rotation axis is prevented. For this reason, the player hits within a certain range of the hitting surface of the electronic pad. Thereby, the arrangement | positioning range of the said operation sensor in an electronic pad can be limited, and it becomes possible to reduce manufacturing cost. Further, the situation where the connected cord is entangled with the pole by the rotation of the electronic pad and is pulled by the pole is also prevented.

  In particular, when the anti-rotation member is loosely fitted in the recess around the mounting hole on the lower surface of the second frame, the electronic pad will swing while preventing the rotation. In this case, the performer can perform with a feeling closer to that of an acoustic cymbal.

Further, the electronic percussion instrument of the present invention is an electronic percussion instrument provided with an electronic pad that receives a hit and outputs a musical tone control signal corresponding to the hit.
A striking sensor for detecting the striking strength;
A first sensor for detecting a hit or operation of the first region;
A second sensor for detecting a hit or operation on the second region;
A third sensor for detecting an operation on the third region;
If there is an output from the batting sensor only,
If there is an output from both the impact sensor and the first sensor, the pronunciation of the second musical sound is
When there is an output from both the impact sensor and the second sensor, the third musical sound is instructed,
If there is an output from the third sensor while the first musical tone or the second musical tone is being generated, the first musical tone or the second musical tone is instructed to be silenced,
When there is an output from the second sensor during the third musical tone, the third musical tone is instructed to be silenced.

Here, in the electronic percussion instrument of the present invention,
The impact sensor output from which the output signal of the impact sensor is output,
The first sensor and the third sensor output terminal from which the output signals of the first sensor and the third sensor are output are defined as a first group,
The impact sensor output from which the output signal of the impact sensor is output,
The second sensor output from which the output signal of the second sensor is output is a second group,
It is preferable that the musical tone control is performed individually for the first group and the second group.

  As described above, according to the present invention, it is possible to mute the mute operation more quickly than before.

  The first embodiment of the present invention will be described below.

  FIG. 1 is a perspective view of an electronic pad 1 used as an electronic cymbal according to the first embodiment of the present invention.

  The electronic pad 1 shown in FIG. 1 includes a cup portion 30 that surrounds the central opening 1a and outputs a dome-like shape, and outputs a sound having a different sound quality depending on the portion to be hit. It can be divided into a peripheral edge portion 32 and an intermediate bow portion 31.

  The upper surface of the electronic pad 1 is covered with a cover 2. As the material of the cover 2, rubber or an elastomer that is a material having both elasticity, which is an advantage of rubber, and productivity, which is an advantage of plastic, is used.

  On the upper surface of the cover 2, concentric irregularities are provided. By this processing, for example, unevenness having a groove width of 2 mm, a pitch of 4 mm (2 mm between the grooves), and a depth of 0.1 mm is provided on the upper surface of the cover 2.

  The top surface of the cover 2 is subjected to a treatment for applying a primer for rubber (reactive surface modification treatment material, scientific reaction type surface treatment material) or the like by dipping, brushing, spraying, etc. The surface has a low coefficient of friction and improved wear resistance. As a result, the sliding of the stick is similar to that when a metal acoustic cymbal is struck, and the wear of rubber when struck with a stick for a long time is reduced. The cover 2 may be formed of a material that has the same effect as the surface treatment and is softer than the first frame 3 described later. Further, the surface treatment such as application of the rubber primer, which will be described later with reference to FIG. Is also applied to prevent wear. In this way, the upper surface of the electronic pad 1 can obtain a good bounce of the stick.

  In the opening 1a at the center of the electronic pad 1 in FIG. 1, a screw part 10a of a pole 10 that supports the electronic pad 1 from below, and a wing nut 13 screwed to the screw part 10a, which will be described later, are sequentially described from the top. A metal washer 12 and a felt washer 11 are shown.

  FIG. 2 is a cross-sectional view taken along the line AA of the electronic pad 1 of FIG.

  FIG. 2B shows an enlarged view of the vicinity of the center of FIG. 2A in which the pole 10, the wing nut 13, the metal washer 12, and the felt washer 11 are removed for convenience.

  The first frame 3 is made of a hard material and has an opening 3c at the center. Further, the upper surface and the lower peripheral edge of the first frame 3 are covered with the cover 2 except for the upper surface of the central opening 3c. As the material of the first frame 3, ABS, polycarbonate, or the like is used.

  In addition, the first frame 3 has an outer peripheral edge 3b having an upper surface that is annularly lowered from the upper surface of the central opening 3c by a step 3a at the outer edge.

  The outer peripheral peripheral edge 2a of the cover 2 that is in contact with the outer peripheral peripheral edge 3b of the first frame 3 is formed thicker than the other portions by the level difference 3a. Therefore, the upper surface of the cover 2, that is, the electronic The upper surface of the pad 1 is finished in a shape that does not feel the presence of the step 3a.

  Moreover, since the outer periphery peripheral part 2a is formed outside the outer periphery peripheral part 3b of the 1st flame | frame 3, it becomes easy to deform | transform when the edge part 32 is struck. Thereby, when the edge part of an acoustic cymbal is hit, the touch which deform | transforms and absorbs an impact is reproducible.

  FIG. 2B shows the second frame 4. The second frame 4 includes a head 4 a protruding upward from the central opening 3 c of the first frame 3, a shoulder 4 b that supports the lower peripheral edge of the opening 3 c from below, and the first frame 3. The arm part 4c which supports the lower surface of the site | part corresponding to the bow part 31 of FIG.

  At the center of the head 4a of the second frame 4, there is provided a mounting hole 4d penetrating vertically as shown in FIG. Further, around the mounting hole 4d on the lower surface of the center of the head portion 4a of the second frame 4, a concave portion 4e that is fitted into a rotation stopper member 9 described later and is shaped like a wedge extending in a predetermined direction. Is provided. The second frame 4 is made of a soft material such as rubber compared to the material of the first frame 3.

  Further, FIG. 2 shows the piezoelectric sensor 5 which is covered with the arm portion 4c of the second frame 4 on the lower surface of the first frame 3 and is in contact with the position on the player side. The piezoelectric sensor 5 detects the impact on the striking surface and the perimeter of the striking surface of the electronic pad 1.

  In FIG. 2, the piezoelectric sensor 5, the edge upper sheet sensor 7, the edge lower sheet sensor 6, and the cup portion sheet sensor 8, which will be described later, are disposed only on the right half of FIG. 2 and on the left half. Absent. The electronic pad 1 is assumed to be hit only in the right half circumference, and these sensors are disposed only within the hit range. The rotation of the electronic pad 1 is prevented by the fitting of the recess 4e of the second frame 4 and the rotation stop member 9, thereby making it possible to limit the hitting range.

  Since the hitting range can be limited, the arrangement of the sensor outside the hitting range is omitted. As a result, manufacturing costs can be reduced.

Here, as described above, the second frame 4 is formed of a material such as a softer rubber than the first frame 3, and has a structure in which the first frame 3 is lifted by the shoulder 4b. Therefore, the second frame 4 is fixed to the pole 10 of the stand, which will be described later, the first frame 3 is free from fixing to the stand, and the vibration generated in the first frame 3 is the first. Propagates smoothly over frame 3. For this reason, the vibration generated in the first frame 3 due to the impact on the striking surface and the perimeter of the striking surface of the electronic pad 1 is efficiently detected by the piezoelectric sensor 5.

  Further, the cover 2 extends to the lower side of the outer peripheral peripheral edge portion 3b of the first frame 3, and rotates to the lower surface of the outer peripheral peripheral edge portion 3b of the first frame 3 and to the lower side of the outer peripheral peripheral edge portion. An edge lower sheet sensor 6 which is an example of an operation sensor according to the present invention is provided between the cover 2 which is indented. In the edge lower sheet sensor 6, the pressure due to the mute operation by the player is detected, and the hit is not detected.

  Further, an edge upper sheet sensor 7 is provided between the upper surface of the outer peripheral edge 3b of the first frame 3 and the cover 2 covering the upper surface of the outer peripheral edge 3b.

  The edge upper sheet sensor 7 detects pressure due to striking or the like on the edge portion 32 at the outer peripheral edge shown in FIG.

  In addition, a cup portion sheet sensor 8 is provided in contact with the upper surface of the first frame 3 at a location where the base portion 30a of the center cup portion 30 of the electronic pad 1 and the first frame 3 are close to each other. .

  Further, the cup portion 30 of the electronic pad 1 shown in a dome shape in FIG. 2 is formed by the cover 2 in which the core material 19 is integrally formed.

  In the core member 19, when the cup part 30 is hit, the peripheral part of the core member 19 presses the cup part sheet sensor 8 through the inner surface of the peripheral part of the cup part 30 of the cover 2.

  Thereby, in this cup part sheet | seat sensor 8, the hit | damage with respect to the cup part 30 is detected.

  As described above, the lower surface of the center of the head portion 4a of the second frame 4 is formed with the concave portion 4e that has a wedge shape extending in a predetermined direction, and is shown in FIG. 2 (b). As shown, the anti-rotation member 9 has a tip portion 9a that is fitted in the recess 4e and protrudes in a wedge shape extending in a predetermined direction.

  Further, the rotation stop member 9 has an insertion hole 9b shown in FIG. 2B through which a pole 10 for supporting the electronic pad 1 from below is inserted. The insertion hole 9b has a shape in which the diameter is once reduced on the way from the bottom to the top.

  On the other hand, the pole 10 has a tip portion 10b having a shape that fits into the insertion hole 9b, that is, a shape in which the diameter becomes smaller on the way to the tip. The rotation stop member 9 is fixed to the pole 10 by a fastener 15 shown in FIG. 3 in a state where the tip end portion 10b of the pole 10 is inserted.

  Furthermore, a screw portion 10 a is provided at the very tip of the pole 10, and this screw portion 10 a protrudes upward from the upper surface of the head 4 a of the second frame 4, and between the anti-rotation member 9, The head 4 a of the frame 4, the felt washer 11, and the metal washer 12 are sandwiched and screwed with a wing nut 13, and the electronic pad 1 is fixed to the pole 10 by the wing nut 13.

  That is, the electronic pad 1 is supported from below by the pole 10 to which the rotation stopping member 9 having the front end portion 9a fitted in the concave portion 4e of the second frame 4 is fixed.

  Here, since the concave portion 4e of the second frame 4 and the tip end portion 9a of the rotation stopping member 9 are fitted, the rotation of the electronic pad 1 around the pole 10 as the rotation axis is prevented. Accordingly, it is possible to prevent a situation in which an output cable 14 (to be described later) of the electronic pad 1 is entangled with the pole 10 or pulled by the pole 10.

  3 is a cross-sectional view of the electronic pad 1 shown in FIG.

  FIG. 3 shows the above-described fastener 15 for fixing the rotation stop member 9 to the pole 10 and the screw 16 for fixing the second frame 4 to the first frame 3.

  In FIG. 3, the lower edge sheet sensor 6, the upper edge sheet sensor 7, and the cup portion sheet sensor 8 are arranged on both the left and right sides of the electronic pad 1. This is because the cross-sectional view shown in FIG. 3 is 90 ° different from the cross-sectional view of FIG. 2, and shows a cross-section when the electronic pad 1 is viewed from the player's position. That's why.

  3 shows an output jack 18 for transmitting output signals from the piezoelectric sensor 5, the edge lower sheet sensor 6, the edge upper sheet sensor 7, and the cup portion sheet sensor 8 to a sound source device (not shown). And output cable 14 is shown.

  The output jack 18 is disposed in a space between the arm portion 4 c of the second frame 4 and the lower surface of the first frame 3 and is fixed to the second frame 4 via the output jack holder 17. . Since the second frame 4 is formed of a material such as rubber, which is softer than the first frame as described above, the second frame 4 is somewhat resistant to pulling on the output cable 14 and vibration of the electronic pad 1. It can be deformed to prevent damage to the output jack. The output jack 18 is composed of two jacks, that is, a first output jack 110 and a second output jack 120 (see FIG. 7). The output signals from the sensors are the first output jack 110 and the second output jack 110, respectively. The sound is output from the second output jack 120 and transmitted to the sound source device (not shown) via the output cable 14. In this embodiment, the number of sensors and the number of terminals are different from each other as described above, but signals from each sensor can be transmitted to the sound source device. This point will be described later.

  FIG. 4 is a perspective view when the electronic pad 1 is viewed obliquely from below.

  FIG. 4 illustrates the cover 2 that wraps downward so as to wrap around the outer peripheral edge of the first frame 3 described above.

  FIG. 4 shows a state in which the electronic pad 1 is supported by a pole 10 to which the rotation stop member 9 is fixed.

  As shown in FIG. 4, the second frame 4 is fixed to the lower surface of the first frame 3 by screws 16 at several locations.

  FIG. 5 is a diagram conceptually showing the impact of the stick 20 on the central cup portion 30, the intermediate bow portion 31, and the peripheral edge portion 32 of the electronic pad 1 shown in FIG. 1, and FIG. It is a figure which shows notionally a mode that the muffling operation by pinching the outer periphery periphery of is performed with a finger | toe.

  When the electronic pad 1 is struck or silenced as shown in FIGS. 5 and 6, the piezoelectric sensor 5, the edge lower sheet sensor 6, the edge upper sheet sensor 7, and the cup portion sheet shown in FIG. Each sensor of the sensor 8 detects vibration and pressure. The output signals from these sensors are combined in the circuit shown in FIG. 7, output from the output jack 18, that is, the first output jack 110 and the second output jack 120, and output to the sound source device (not shown) via the output cable 14. Communicated.

  In the sound source device, when the parts corresponding to the center cup part 30, the intermediate bow part 31, and the peripheral edge part 32 shown in FIG. The sound of typical tones of each part, so-called cup sounds, bow sounds, timbre sounds simulating edge sounds are stored, and based on the combination of output signals transmitted via the output cable 14 Thus, the tone of the timbre corresponding to the striking part is pronounced or the tone is muted.

  Next, the correspondence between the output of each sensor, the striking position, and the mute operation (edge choke) will be described. Table 1 shows the correspondence.

  The piezoelectric sensor 5 outputs a signal when hitting any of the cup part 30, the bow part 31 and the edge part 32 in FIG. 1, and remains off in the case of an edge part choke. Moreover, the cup part sheet sensor 8 is turned on only when the cup part 30 is hit. The edge upper sheet sensor 7 remains off during the performance of the cup part 30 and the bow part 31, and is turned on when the edge part 32 is hit and when the edge part is choked. Further, the edge lower sheet sensor 6 is turned on only in the case of the edge choke.

  That is, the edge lower sheet sensor 6 does not react to the impact, but detects only an operation on the peripheral edge of the electronic pad 1 called edge choke.

  FIG. 7 is a wiring diagram of a jack portion for transmitting an output signal from each sensor to a sound source.

  Here, two terminals A1 and A2 connected to the first output jack 110 and two terminals B1 and B2 connected to the second output jack 120 are shown. The output signal from the piezoelectric sensor 5 is transmitted to both the terminal A1 and the terminal B1. Further, both the edge lower sheet sensor 6 and the cup portion sheet sensor 8 are connected to the terminal A2, but as shown in Table 1, both the edge lower sheet sensor 6 and the cup portion sheet sensor 8 are simultaneously turned on. It is possible to determine which of the edge lower sheet sensor 6 and the cup part sheet sensor 8 is on by looking at the output of the piezoelectric sensor 5 without the presence of the timing. Therefore, both of the output signals from the edge lower sheet sensor 6 and the cup sheet sensor 8 can be output from the terminal A2.

  The edge upper sheet sensor 7 is connected to the terminal B2 of the second output jack 120.

  Table 2 is a table showing the correspondence between the output of each terminal and the assigned sound.

  Here, only the first output jack 110 or only the second output jack 120 can be connected to the sound source device. When only the first output jack is connected, the cup sound and the bow sound are generated and muted. When only the second output jack is connected, only the edge sound is produced and silenced.

  When there is an output of the piezoelectric sensor 5 from the terminal A1 of the first output jack 110 and there is no output from the terminal A2 of the first output jack 110, a bow sound is assigned as a sound to be generated. When there is an output from both the terminal A1 and the terminal A2 of the first output jack 110, a cup sound is assigned. When there is no output from the piezoelectric sensor 5 from the terminal A1 of the first output jack 110 and there is an output from the terminal A2 (in this case, the edge lower sheet sensor 6 is turned on), the sound is silenced.

  When there is an output from the terminal B1 of the second output jack 120 and there is no output from the terminal B2, no sound is generated and the sound is kept silent, and there is an output from both the terminal B1 and the terminal B2. When an edge sound is generated. Further, there is no output from the terminal B1, and when there is an output from the terminal B2, that is, when the edge upper sheet sensor 7 is ON, the sound is silenced. At this time, without using the edge lower sheet sensor 6, an operation for muting (edge choke) can be immediately detected by a combination of the output of the piezoelectric sensor 5 and the output of the edge upper sheet sensor 7. . However, the electronic pad 1 as a whole requires the edge lower sheet sensor 6 that detects the choke at the edge without detecting the hitting in order to instantaneously detect the mute operation (choke at the edge).

  As described above, when the cup portion 30 of the electronic pad 1 in FIG. 1 is hit, signals are transmitted from the terminals A1, A2, and B1, and the sound generator generates a cup sound. Similarly, when the middle bow portion 31 is hit, a signal is transmitted from both the terminal A1 and the terminal B1, and the sound generator generates a bow sound. Further, when the outer peripheral edge 32 is hit, a signal is transmitted from each of the terminal A1, the terminal B1, and the terminal B2, and the sound source device generates an edge sound. As shown in Table 2, when the edge sound is pronounced, the bow sound is also pronounced at the same time, but the edge sound is often used as an accent, and the volume is set to be large. Since the sound is masked by the edge sound and the edge sound originally includes the characteristic of the bow sound, even if the edge sound is overlaid with the bow sound, the influence can be almost ignored.

  Further, as shown in FIG. 6, the edge lower sheet sensor 6 and the edge upper sheet are respectively detected from the terminals A2 and B2 by an operation of picking the edge of the striking surface of the electronic pad 1 with a finger (edge choke). The signal of the sensor 7 is transmitted, and the sound source device is silenced.

  Further, the sound source device monitors not only the presence or absence of output of the pressure sensor 5 but also the magnitude of its output signal, and the sound output of each of the above-mentioned sounds depends on the magnitude of the output signal of the piezoelectric sensor. Pronunciation at a certain volume. In general, a sheet sensor detects on / off in the same manner as a switch. Compared to a conventional method of selecting a timbre after monitoring a vibration by a piezoelectric sensor or the like and determining a striking position, the sheet sensor. The timbre can be selected more quickly by using the signal to monitor the on state of the sheet sensor. In the present embodiment, a sheet sensor is used, and therefore, it is possible to deal with pronunciation such as a cup sound that is used as an accent, that is, a quick sound is necessary for performance, and the edge sound described above. In this case, the sound generation of the sound is quickly performed at a certain volume, and then an envelope process for adjusting the volume according to the hitting force is performed.

  Thus, in the above-described embodiment, the sound of the timbre corresponding to the striking part is generated at a volume corresponding to the striking force by striking the striking surface and the perimeter of the striking surface of the electronic pad 1, and by the mute operation shown in FIG. The sound being pronounced will be muted more quickly than before.

  Here, even when only the first output jack 110 of the first output jack 110 and the second output jack 120 is connected to the sound source device, the edge lower sheet sensor 6 disposed at a position avoiding the position that reacts to the hitting. By turning on the sound by the mute operation, the performer can mute the cup sound and bow sound that are being generated more quickly than before. It should be noted that control may be performed so as to suppress the sound of the bow sound when the sound source device performs sound generation of the edge.

  FIG. 8 is a view showing a state where the electronic pad 1 supported by the pole 10 is hit by the stick 20 and tilted.

  The anti-rotation member 21 shown in FIG. 8 has a wedge-shaped tip portion 21a as compared with the anti-rotation member 9 shown in FIG. For this reason, the wedge shape of the distal end portion 21a of the rotation stop member 21 is in a loosely fitted state without completely fitting with the concave portion 4e of the second frame 4, and is easily received when hit as shown in FIG. Will tilt.

  In this way, several types of anti-rotation members with different wedge-shaped angles are prepared, and by using this anti-rotation member properly depending on the size and weight of the acoustic cymbal to be simulated, it is different for each cymbal while preventing the rotation of the striking surface, The degree of shaking due to the impact can be adjusted, and it is possible to perform with a feeling close to that of an acoustic cymbal. The degree of shaking can also be adjusted by the degree of tightening of the wing nut 13 of the threaded portion 10a of the pole 10.

  Alternatively, the anti-rotation member may be fixed to one kind of anti-rotation member that can be sufficiently shaken, and the clearance between the anti-rotation member and the recess 4e of the second frame 4 may be adjusted with a spacer or an adapter. While preventing the striking surface from rotating, it is possible to perform with a feeling similar to an acoustic cymbal to be simulated.

  Further, the center axis of the shaking of the electronic pad 1 that occurs when the electronic pad 1 is struck is in the cross section when the cross section is taken along the arrow BB shown in FIG. Here, since the output jack 18 is disposed in the vicinity of the center axis of the shaking, the vertical movement of the output cable 14 due to the shaking is suppressed. Therefore, overloading to the output cable 14 itself and the portion to which the output cable 14 is connected due to the weight of the output cable is prevented, and the life of the electronic pad 1 can be extended.

  Next, a second embodiment of the present invention will be described.

  FIG. 9 is a diagram showing an electronic pad 41 used as an electronic cymbal according to the second embodiment of the present invention.

  FIG. 9 shows a frame 43 and a cover 42 that covers the upper surface of the frame 43, and the left half surface of the cover 42 is removed to make it easy to see the later-described features of the frame 43.

  An outer peripheral edge 43a similar to that of the electronic pad 1 is provided on the outer peripheral edge of the frame 43 of the electronic pad 41. The outer peripheral edge 43a has a portion 43b that avoids the hitting range by the player. Thus, the shape is cut off.

  A portion 42b of the outer peripheral peripheral edge portion 42a of the cover 42 is in close contact with the portion 43b. For this reason, the portion 42b of the cover 42 has a shape in which a space portion corresponding to 43b that is partially cut off of the frame 43 is clogged. Is formed.

  The electronic pad 41 is different from the electronic pad 1 of FIG. 1 in two points, namely, the partial cut-off of the outer peripheral edge 43a of the frame 43 and the partial shape change of the peripheral edge 42a of the cover 2. Accordingly, as shown on the frame 43 of FIG. 9, the head 4a and the insertion hole 4d of the second frame 4 protruding in the center, the cup seat sensor 8 near the center, and the frame 43 are shown. As the upper edge sheet sensor 7 on the outer peripheral edge 43a, the same type as shown in FIG. 2 is used. Although not shown in FIG. 9, the lower edge sheet sensor 6 is also provided on the lower surface of the outer peripheral edge 43a of the frame 43, as in the electronic pad 1 of FIG.

  The arrows CC and DD in FIG. 9 correspond to the arrows AA and BB in FIG. 1, and the edge upper sheet sensor 7 in FIG. 9, the edge lower sheet sensor 6 not shown, and the cup portion The sheet sensor 8 is arranged in the same range as the arrangement range of the sensors in the electronic pad 1 described above.

  That is, these sensors are arranged in the right half of FIG. 2, that is, in the lower half of D from D to D in FIG. 9, and are not arranged in the upper left of D to D. For this reason, the manufacturing cost is reduced by arranging the sensors only on the player side half circumference.

Furthermore, by partially cutting off the outer peripheral edge 43a of the frame 43, the shape becomes a rotating body and the balance of rigidity is lost. In contrast, since the shape of the cover 2 is partially different as described above, the weight balance of the electronic pad 41 centered on the insertion hole 4d of the electronic pad 41 is not lost, and the balance of rigidity of the frame 43 is delicately balanced. This collapses and suppresses acoustic resonance, and in the electronic pad 41 of the second embodiment, unnecessary vibration generated in the frame 43 is further suppressed.
Further, the center of gravity of the electronic pad 41 is deviated from the center of the appearance of the electronic pad 41, that is, the insertion hole 4d in FIG. On the other hand, the electronic pad 41, like the electronic pad 1 of FIG. 1, is inserted from the bottom by inserting a pole 10 (not shown) to which the anti-rotation member 9 is fixed into the insertion hole 4d shifted from the center of gravity. It is supported.
