DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. An electronic keyboard instrument 10 as an electronic device shown in Fig. 1 includes a 61-key keyboard 11 and an instrument case 20. In the following description, the front of the keys in the front-rear direction FB of the keyboard 11 is referred to as the front side F, the rear of the keys in the front-rear direction FB is referred to as the rear side B, the left side as viewed from the front of the keyboard 11 is referred to as the left side L, and the right side as viewed from the right is referred to as the right side R. The direction LR in which the keys are arranged on the keyboard 11 is the left-right direction. Also, in the vertical direction UL of the electronic keyboard instrument 10, the top is referred to as the upper side Up, and the bottom is referred to as the lower side Lo.

[0012] The instrument case 20 (receiving member) is a generally rectangular plate with the longitudinal direction being the left-right direction, and comprises an upper case 21 (receiving member) and a lower case 22. The upper case 21 and the lower case 22 are each manufactured by injection molding of a resin material, and are connected by bolts (not shown). Inside the instrument case 20, a circuit board, a battery as a power source, etc. are stored.

[0013] 1 and 2, a top surface member 30 (mounting member) is disposed on the rear side B of the keyboard 11. The top surface member 30 has a console panel 31 (first mounting member) and a speaker cover 32 (second mounting member), both of which are manufactured by injection molding of a resin material. The console panel 31 is long in the key arrangement direction LR, and is provided with an operation unit 310 that includes a power button 311, operation buttons 312, a volume knob 313, and an LED display unit 314 that displays the operation state. The speaker cover 32 is wrapped in fabric 33.

[0014] As shown in FIG. 2, the top surface member 30 is attached to the top surface member attachment portion 21a of the upper surface rear side B of the upper case 21, which is substantially concave. The top surface member attachment portion 21a is provided with pin insertion holes 55 (second female parts) at both ends in the key arrangement direction LR on the front side F of the top surface member attachment portion 21a. The pin insertion holes 55 are slightly elongated holes in the key arrangement direction LR. As shown in the enlarged view of P1 in FIG. 2, which shows an enlarged view of the periphery of the left pin insertion hole 55, the pin insertion hole 55 has a straight part 55a provided in parallel to the front side F and the rear side B, and an arc-shaped part 55b connecting the two straight parts 55a at both ends. The pin insertion hole 55 is provided at a position corresponding to a pin 51 (second male part) described later. The top surface member attachment portion 21a has wall parts 21b erected on the edges of the left and right sides and the rear side B.

[0015] 3, a substrate 315 is provided on the inner surface of the top surface member 30 corresponding to the operation unit 310. The substrate 315 is provided across the console panel 31 and the speaker cover 32 in the front-rear direction FB. Furthermore, a plurality of bosses 34 having female threads for fixing the top surface member 30 to the upper case 21 with bolts 210 (see FIG. 2) are provided near the edges of the front side F and rear side B of the top surface member 30 (i.e., the console panel 31 and the speaker cover 32).

[0016] As shown in Figs. 3 and 7, the console panel 31 has a front plate 31a arranged on the front side F of the electronic keyboard instrument 10, and an upper plate 31b on which an operating unit 310 is provided. The front plate 31a and the upper plate 31b are connected so as to be substantially perpendicular to each other in a side view of the key arrangement direction LR. As shown in Figs. 3 and 4, triangular rib-shaped side plates 31c that connect to the front plate 31a and the upper plate 31b are provided at both ends of the console panel 31 in the key arrangement direction LR. The outer surface of the front plate 31a is provided with a long uneven surface in the key arrangement direction LR. As shown in Fig. 6, a plurality of square column-shaped ribs 31a1 are provided on the inner surface of the front plate 31a. A felt member 36 is arranged between the lower end of the front plate 31a and the upper surface of the keyboard 11 and extends in the key arrangement direction LR.

[0017] 4 and 7, the upper plate 31b of the console panel 31 has an upper plate main body 31b1 on which the operation unit 310 is provided and which is exposed to the outside, and an upper plate connection part 31b2 which is connected to the upper plate main body 31b1 via a step part 31d. The upper surface of the upper plate connection part 31b2 is located on a lower side Lo than the upper surface of the upper plate main body 31b1. Both ends of the upper plate connection part 31b2 in the key arrangement direction LR are provided with arc-shaped parts 31e which imitate the arc-shaped edges of the speaker hole 32a of the speaker cover 32 which will be described later.

[0018] The console panel 31 is provided with pins 51 (second male parts) protruding in a second direction D2 different from a first direction D1 described later on the inner surface of the upper plate main body part 31b1 near both ends in the key arrangement direction LR. As shown in FIG. 6, the pins 51 are provided in a substantially cross shape with the front-rear plate 51a and the left-right plate 51b intersecting at right angles. Therefore, the edge surface 51a1 of the front-rear plate 51a is disposed facing the front side F and the rear side B. On the other hand, the edge surface 51b1 of the left-right plate 51b is disposed facing the right side R in the pin 51 on the left side L shown in FIG. 6, and is disposed facing the left side L in the pin 51 on the right side R. The base part 51c on the outer side (opposite the edge surface 51b1) of the left-right plate 51b has a reinforcing rib 31g connected to the inner surface of the side plate 31c via a boss 34. The front and rear plates 51a and the left and right plates 51b have tapered tip portions 51d, base portions 51c which are wider than the tip portions 51d, and the tip portions 51d and base portions 51c are connected by a step portion 51e.

[0019] An edge wall 31f is provided on the edge of the rear side B of the upper plate connection part 31b2. A blade member 61 (also called a male part (first male part), protruding piece, or fin) protruding in the first direction D1 from an edge surface 31f1 of the edge wall 31f (i.e., the outer periphery of the console panel 31) is extended near both ends of the edge wall 31f in the key arrangement direction LR (i.e., near both ends of the console panel 31). The blade member 61 is a substantially triangular plate with its oblique side facing inward (the right side R in the left blade member 61, and the left side L in the right blade member 61), and is provided so that its flat surface faces the up-down direction UL. A felt member 62, which is a cloth member, is attached to the flat surface portion, which is the surface from the upper side Up to the lower side Lo of the blade member 61, via the tip portion. Furthermore, three substantially triangular ribs 63 are provided at the base of the blade member 61 in the key arrangement direction LR, connecting the edge surface 31f1 and the surface of the lower side Lo of the blade member 61. The blade member 61 is tapered so that the plate thickness gradually increases from the tip to the base. In this way, the pin 51 and the blade member 61 extend in directions substantially perpendicular to each other. In other words, the first direction D1 and the second direction D2 are perpendicular to each other.

[0020] As shown in Fig. 7, a plurality of boss arrangement portions 37 are provided on the upper plate connection portion 31b2 of the console panel 31. The boss arrangement portion 37 is arranged so that a boss 35 provided on the speaker cover 32 described below is positioned thereon. The boss arrangement portion 37 has a first boss arrangement portion 37a, a second boss arrangement portion 37b, and a third boss arrangement portion 37c, which have different internal shapes. The boss arrangement portion 37 is arranged in the key arrangement direction LR in the following order from the left side L in Fig. 7: the first boss arrangement portion 37a, the third boss arrangement portion 37c, the second boss arrangement portion 37b, the third boss arrangement portion 37c, the second boss arrangement portion 37b, and the first boss arrangement portion 37a.

[0021] As shown in the enlarged views (Q1 to Q3) of FIG. 6 and FIG. 7, the boss arrangement portion 37 has a U-shaped wall portion 37-1 that is substantially U-shaped with the rear side open in a plan view, and a bottom plate 37-2 that connects the U-shaped wall portion 37-1 to the lower side Lo. The U-shaped wall portion 37-1 is connected to the edge wall portion 31f. The U-shaped wall portion 37-1 is tapered so that the width gradually narrows from the upper side Up to the lower side Lo. The bottom plate 37-2 is provided with a hole portion 37-3 through which the bolt 220 (see FIG. 4) is inserted. As shown in the enlarged views of Q1 and Q3 of FIG. 7, the first boss arrangement portion 37a and the third boss arrangement portion 37c are provided in the concave interiors of the first boss arrangement portion 37a and the third boss arrangement portion 37c with arc-shaped restricting wall portions 37a1 and 37c1 that stand up from the surface of the upper side Up of the bottom plate 37-2. The restricting walls 37a1, 37c1 are formed in a convex arc shape toward the rear side B, and ribs 37a2, 37c2 are provided in the approximate center. The length in the front-rear direction FB of the rib 37a2 of the first boss arrangement portion 37a is longer than the rib 37c2 of the third boss arrangement portion 37c. In addition, the surface of the upper side Up of the bottom plate 37-2 of the second boss arrangement portion 37b is flat.

[0022] In addition, the first boss arrangement portion 37a and the third boss arrangement portion 37c of the boss arrangement portion 37 are provided so that the distance in the front-rear direction FB of the bottom plate 37-2 is slightly larger than the diameter of the boss 35 of the speaker cover 32 and is substantially the same. On the other hand, the bottom plate 37-2 of the third boss arrangement portion 37c-1 near the volume knob 313 of the third boss arrangement portion 37c is provided in a circular shape as shown in FIG. 8. That is, the diameter of the bottom plate 37-2 of the third boss arrangement portion 37c-1 near the volume knob 313 is slightly larger than the diameter of the boss 35 of the speaker cover 32 and is substantially the same. On the other hand, the boss arrangement portions 37 other than the third boss arrangement portion 37c-1 are provided so that the key arrangement direction LR is larger than the boss 35 so that the boss 35 can escape when positioning.

[0023] That is, when the boss 35 is arranged in the boss arrangement portion 37, it is positioned in the front-rear direction FB by the first boss arrangement portion 37a and the third boss arrangement portion 37c, and is positioned in the key arrangement direction LR by only the third boss arrangement portion 37c-1 near the volume knob 313. Therefore, the first boss arrangement portion 37a and the third boss arrangement portion 37c arranged at a predetermined interval can make the gap between the front end edge of the speaker cover 32 (a front wall portion 32e described later) and the step portion 31d of the console panel 31 uniform. Note that the gap between the front end edge of the speaker cover 32 at both ends (left and right outer sides of the boss arrangement portion 37a) of the console panel 31 in the key arrangement direction LR and the step portion 31d of the console panel 31 is adjusted by fitting a pin 51 described later into a pin insertion hole 55.

[0024] The positioning of the console panel 31 and the speaker cover 32 in the key arrangement direction LR is determined only by the third boss arrangement portion 37c-1 near the volume knob 313, and the gap between the annular rib portion 31b3 around the volume knob 313 (described later) and the cutout portion 32c of the speaker cover 32 corresponding to the annular rib portion 31b3 is adjusted to be uniform. In particular, since the speaker cover 32 is provided with the fabric 33, any unevenness in the gap between the annular rib portion 31b3 and the cutout portion 32c is easily noticeable, so this configuration in which the positioning of the speaker cover 32 relative to the console panel 31 in the front-rear direction FB and the key arrangement direction LR is determined by the third boss arrangement portion 37c-1 near the volume knob 313 is preferable.

[0025] As shown in Figures 8 and 9, an annular rib portion 31b3 formed in an arc shape is provided on the upper surface of the upper plate connecting portion 31b2 on the outer periphery of the volume knob 313. Furthermore, as shown in Figures 8 and 10, a rib portion 31b4 extending in the key arrangement direction LR is provided near the step portion 31d on the upper surface of the upper plate connecting portion 31b2. It should be noted that no rib portion 31b4 is provided on the outer periphery side of the annular rib portion 31b3 (see also Figure 9).

[0026] As shown in FIG. 10, the rib portion 31b4 can receive the surface of the lower side Lo of the front wall portion 32e of the speaker cover 32. Since the rib portion 31b4 is not provided on the outer periphery of the annular rib portion 31b3, the upper plate connecting portion 31b2 does not bend even if the speaker cover 32 is pressed from above. Therefore, the upper plate connecting portion 31b2 does not press the flange portion 313a (see FIG. 9) of the volume knob 313 and inhibit the rotation of the volume knob 313. In addition, the annular rib portion 31b3 reduces the possibility of the fabric 33 being caught when the volume knob 313 arranged adjacent to the overlapping arrangement portion 75 described below is rotated.

[0027] 1 and 2, a flat speaker cover 32 having approximately the same width in the key arrangement direction LR as the console panel 31 is provided on the rear side B of the console panel 31. The speaker cover 32 has speaker hole portions 32a with multiple holes corresponding to the speakers 13 arranged near both ends of the top surface of the upper case 21, as shown in FIG.

[0028] As shown in Figures 3 and 4, the speaker hole 32a has an annular wall 32a1 on its outer periphery. The wall 32a1 is an elongated rectangle with semicircular corners at both ends. As shown in Figure 4, a plurality of bosses 35 for connecting to the console panel 31 are erected from the inner surface of the front side F of the speaker cover 32. The bosses 35 are provided with female threads and are arranged in the key arrangement direction LR in correspondence with the boss arrangement portion 37.

[0029] A wall portion 32d is provided on the rear side B and the left and right side edges of the speaker cover 32 so as to protrude to the lower side Lo. A front wall portion 32e is provided on the edge of the front side F of the speaker cover 32 so as to connect the ends of the wall portions 32d on the left and right side edges. As shown in FIG. 5, a step portion 32d1 is provided on the inside of the wall portion 32d. The front wall portion 32e is sufficiently lower in height than the wall portion 32d. A groove portion 32f is provided on the inner surface (the surface of the lower side Lo) of the speaker cover 32 near the inside of the front wall portion 32e, which is the edge portion facing the console panel 31, and extends linearly in the key arrangement direction LR along the edge portion that is the front wall portion 32e (see also FIGS. 9 and 10). In the manufacturing process of wrapping the fabric 33 around the speaker cover 32, the fabric 33 wrapped around the speaker cover 32 is cut with a utility knife or the like, and in the wall portion 32d which is relatively tall, the fabric can be cut along the edge line of the step portion 32d1 of the wall portion 32d. In the front wall portion 32e which is short, the blade of a utility knife or the like for cutting the fabric 33 can be inserted into the recessed groove portion 32f to cut the fabric 33.

[0030] Ribs 32b arranged in a lattice pattern extending in the front-rear direction FB and the key arrangement direction LR are appropriately connected to the wall 32a1 of the speaker hole 32a, the wall 32d erected on the outer periphery of the speaker cover 32, and the bosses 34 and 35 into which the bolts 210, 220 are screwed. Also, as shown in Fig. 7, a semicircular cutout 32c is provided in the speaker cover 32 at a portion corresponding to the volume knob 313 (annular rib 31b3).

[0031] As shown in Fig. 4, the speaker cover 32 has insertion portions 65 provided near both ends on its inner surface. As shown in Fig. 5, the insertion portions 65 are provided at corners of the front side F of the speaker cover 32, which are positions corresponding to the blade members 61. The insertion portions 65 are shaped like a rectangular box that is long in the key arrangement direction LR, and the front side F has flat hole portions 65a (also called first female portions, protruding piece insertion holes, or long holes) that open in a rectangular shape that is long in the key arrangement direction LR. The insertion portions 65 are connected to the wall portions 32a1 of the speaker hole portions 32a, and this connection portion is shaped like a concave arc following the shape of the wall portions 32a1.

[0032] That is, an electronic device according to an embodiment of the present invention includes a first mounting member (console panel 31) having a first male portion (blade member 61) protruding from the outer periphery in a first direction D1, a second mounting member (speaker cover 32) having a first female portion (flat hole portion 65a) with which the first male portion fits, a mounting member (upper surface member 30), and a mounting receiving member (musical instrument case 20, upper case 21) to which the mounting member is attached. The mounting member includes either a second male portion (pin 51) extending in a second direction D2 different from the first direction D1 or a second female portion (pin insertion hole 55) corresponding to the second male portion, and the mounting receiving member includes the other of the second male portion and the second female portion. The first male part and first female part protruding in the first direction D1 suppress bending in the vertical direction, while the second male part (pin 51) extending in the second direction D2 is inserted into the second female part (pin insertion hole 55) to adjust the gap between the first and second mounting parts, thereby enabling the first and second mounting parts and the mounted part to be fixed to one another satisfactorily.

[0033] More specifically, the first boss arrangement portion 37a of the top surface member 30 in the key arrangement direction LR is positioned in the key arrangement direction LR and the front-rear direction FB by the shape of the bottom plate 37-2 of each boss arrangement portion 37 described above, and is fixed by the bolt 220 to be positioned in the up-down direction UL. On the other hand, there is not enough space at both ends of the top surface member 30 because the speaker 13 is arranged there, so the boss arrangement portion 37 could not be provided. However, the blade member 61, the flat hole portion 65a, the pin 51, and the pin insertion hole 55 position the keys in the key arrangement direction LR, the front-rear direction FB, and the up-down direction UL. In this way, even in a location with space restrictions, the first attachment member and the second attachment member, and the attachment member and the attached member can be satisfactorily fixed to each other.

[0034] Moreover, the first male part includes a wide protruding piece (wing member 61) that protrudes in the first direction D1, and the length of this protruding piece in the width direction (key arrangement direction LR) is longer than the length in the thickness direction (plate thickness of the wing member 61). Moreover, the first female part into which the protruding piece is inserted includes an elongated hole whose length in the width direction (width direction of the flat hole portion 65a, key arrangement direction LR) is longer than the length in the thickness direction (height direction of the flat hole portion 65a). This ensures the strength of the first male part even if the first male part comes into contact with the first female part in the up-down and left-right directions when the plate-shaped first mounting member and the plate-shaped second mounting member are combined.

[0035] Either the first mounting member or the second mounting member has a boss 35 extending in the second direction D2. The other of the first mounting member or the second mounting member has a boss arrangement portion 37. The first mounting member and the second mounting member are fixed at the boss arrangement portion 37 with the first male part and the first female part extending in the first direction D1 engaged, and then attached to the member to be mounted. Since the first mounting member and the second mounting member are fixed at the boss arrangement portion 37 with the first male part and the first female part extending in the first direction D1 engaged, the first mounting member and the second mounting member have the advantage that they are well combined and difficult to come off.

[0036] Next, a manufacturing method of an electronic device according to an embodiment of the present invention will be described. First, as shown in Fig. 11(a) and Fig. 11(b), in the first step, the first male part (wing member 61) protruding in the first direction D1 from the outer periphery of the first mounting member (console panel 31) is fitted into the first female part (flat hole portion 65a) in the second mounting member (speaker cover 32). Since the volume knob 313 (convex portion) is provided on the first mounting member side and the cutout portion 32c (concave portion) is provided on the second mounting member side, the first mounting member and the second mounting member can be easily fitted together. In addition, the boss 35 provided closest to the cutout portion 32c has the function of determining the positions of the first mounting member and the second mounting member.

[0037] Next, as shown in FIG. 12(a) and FIG. 12(b), in the second step, a second male part (pin 51) extending in a second direction D2 different from the first direction D1 provided on either the first mounting member or the second mounting member is fitted into a second female part (pin insertion hole 55) included in the mounting member (upper case 21) (first embodiment of the second step), or a second male part extending in a second direction different from the first direction included in the mounting member is fitted into a second female part provided on either the first mounting member or the second mounting member (second embodiment of the second step). As a result, the mounting member including the first mounting member and the second mounting member is attached to the mounting member, so that each member can be fixed to each other well. Therefore, even if the assembly work is performed manually, an electronic device in which the gap between the first mounting member and the second mounting member is well adjusted can be manufactured.

[0038] Then, in the second step, when the second male part is fitted into the second female part, the wall surface sliding part 70 provided on either one of the first mounting member and the second mounting member comes into contact with the wall part 21b included in the mounting member. Then, after the wall surface sliding part 70 comes into contact with the wall part 21b, the gap between the first mounting member and the second mounting member (the gap between the front end edge of the speaker cover 32 and the step part 31d of the console panel 31) is adjusted so as to be narrower than before the wall surface sliding part 70 comes into contact with the wall part 21b (i.e., the state of FIG. 12(a)). In this embodiment, the first mounting member and the second mounting member are not fixed at both ends. Therefore, the gap between the first mounting member and the second mounting member at both ends is likely to be larger or smaller in the front-rear direction of the key than the gap in other parts other than both ends. However, by adopting such a manufacturing method, an electronic device in which the gap between the first mounting member and the second mounting member is well adjusted by the wall surface sliding part 70 can be manufactured. That is, it is possible to provide an electronic device with a good appearance.

[0039] A manufacturing method of the electronic keyboard instrument 10 as an electronic device is specifically as follows. When combining the console panel 31 and the speaker cover 32, the blade member 61 is inserted and fitted into the flat hole portion 65a of the insertion portion 65 as shown in Fig. 11(a). The blade member 61 is pressed into the flat hole portion 65a by the felt member 62 and the tapered shape. As a result, the blade member 61 abuts against the flat hole portion 65a in a direction perpendicular to the flat portion. Meanwhile, the blade member 61 has a predetermined clearance with respect to the key arrangement direction LR of the flat hole portion 65a. Therefore, the blade member 61 is positioned in the up-down direction UL of the flat hole portion 65a.

[0040] Further, here, enlarged views of Q1 and Q3 in FIG. 7 and FIG. 10 are referred to. When the console panel 31 and the speaker cover 32 are assembled, the boss 35 is stored in the boss arrangement portion 37. At this time, the boss 35 arranged in the first boss arrangement portion 37a and the third boss arrangement portion 37c abuts against the boss 35 in the front-rear direction FB by the restricting wall portions 37a1 and 37c1 and the lower end of the U-shaped wall portion 37-1. In this manner, the boss 35 is positioned in the front-rear direction FB. The position of the boss 35 in the key arrangement direction LR is approximately positioned by the wall portion of the U-shaped wall portion 37-1 in the key arrangement direction LR. The boss 35 corresponding to the third boss arrangement portion 37c-1 is positioned in the key arrangement direction LR by the bottom plate 37-2 of the third boss arrangement portion 37c-1 near the volume knob 313, and the speaker cover 32 is positioned in the key arrangement direction LR with respect to the console panel 31.

[0041] When the boss 35 is disposed in the boss arrangement portion 37 (the first boss arrangement portion 37a and the third boss arrangement portion 37c), the tip of the boss 35 is guided by sliding contact on the inclined surface of the rib 37c2, so that the boss 35 is smoothly disposed between the U-shaped wall portion 37-1 and the restricting walls 37a1, 37c1. The bolt 220 is screwed into the boss 35 disposed in the boss arrangement portion 37, and the console panel 31 and the speaker cover 32 are fixed.

[0042] When the console panel 31 and the speaker cover 32 are combined, the vicinity of the front side F of the speaker cover 32, including the front wall portion 32e, is disposed on the upper side Up of the upper plate connection portion 31b2 of the console panel 31. In this manner, the console panel 31 and the speaker cover 32 have an overlapping arrangement portion 75 in which one is disposed on the upper side Up and the other is disposed on the lower side and overlaps. As shown in FIG. 11(b), after the console panel 31 and the speaker cover 32 are combined, the bolt 220 and the female thread portion of the boss 35 are screwed together via the boss arrangement portion 37 to fix the console panel 31 and the speaker cover 32 to each other.

[0043] 12(a), the top member 30 including the combined console panel 31 and speaker cover 32 is attached to the upper case 21 of the musical instrument case 20. At this time, the pin 51 is inserted into the pin insertion hole 55. The front edge surface 51a1 of the front / rear plate 51a of the pin 51 abuts against the plate thickness surface of the straight portion 55a on the front side F of the pin insertion hole 55. In this way, since the flat surfaces in the front / rear direction FB can abut against each other, it is easier to set the amount of correction for warping of the console panel 31 compared to engagement between a round pin and a round hole.

[0044] As shown in FIG. 12(b), the wall 32d of the rear side B of the speaker cover 32 and the wall 21b of the rear side B of the top member attachment portion 21a are opposed to each other. The top member 30 has a wall sliding portion 70 on the surface opposed to the upper case 21. The console panel 31 is a member manufactured by injection molding that is long in the key arrangement direction LR, and may warp toward the front side F at both ends and toward the rear side B at approximately the center. Then, a gap may be generated between the edge (front wall portion 32e) of the front side F of the speaker cover 32 and the step portion 31d near both ends of the console panel 31. However, the pin 51 is inserted into the pin insertion hole 55, and the warp of the console panel 31 is corrected. When the amount of correction is large, the wall portion 32d and the wall portion 21b of the wall surface sliding portion 70 slide at approximately the center in the key arrangement direction LR, and the warp of the console panel 31 is corrected together with the correction by inserting the pin 51 into the pin insertion hole 55.

[0045] That is, when the pin 51 is inserted into the pin insertion hole 55 to attach the mounting member (top member 30) to the mounting base member (upper case 21, instrument case 20), the wall surface sliding portion 70 of the mounting member comes into contact with the mounting base member, thereby adjusting the gap between the first mounting member and the second mounting member.

[0046] 12(b), the upper surface member 30 is fixed to the upper case 21 by screwing the bolt 210 into the female thread of the boss 34. Here, the bolts 210 on the rear side B screw into the female thread of the boss 34 (see FIGS. 3 and 4) on the rear side B of the speaker cover 32 through the corresponding bolt hole 21c on the rear side B of the upper case 21 as shown in FIG. 2. The bolt hole 21c has a seat 21c1 against which the tip of the boss 34 abuts. The seat 21c1 of the substantially central bolt hole 21c of the multiple bolt holes 21c is provided in a substantially circular shape (see the enlarged view of P2 in FIG. 2). On the other hand, the length in the key arrangement direction LR of the bolt hole 21c other than the substantially central bolt hole 21c (representatively, the enlarged view of P3 in FIG. 2) is larger than the diameter of the boss 34. Therefore, in the key arrangement direction LR, the top surface member 30 is positioned relative to the upper case 21 by the seat surface 21c1 of the bolt hole portion 21c at approximately the center. Since the bolt hole portion 21c is provided across the key arrangement direction LR of the top surface member attachment portion 21a of the upper case 21, the top surface member 30 can be arranged in a well-balanced manner on the upper case 21 by using the bolt hole portion 21c at approximately the center as the positioning point. As described above, the pin insertion hole 55 is provided in an elongated hole shape with the key arrangement direction LR as the major axis direction, so that the pin 51 is allowed to escape in the key arrangement direction LR. Furthermore, the length in the front-rear direction FB of the seat surface 21c1 of the bolt hole portion 21c is slightly larger than and approximately equal to the diameter of the boss 35.

[0047] After the top surface member 30 is attached to the upper case 21, the upper case 21 with the top surface member 30 attached is assembled to the lower case 22, to which other components such as the keyboard 11 are attached, by using a bolt (not shown) that screws into the female threaded portion of the fixing boss 21d that stands upright from the upper case 21, thereby manufacturing the electronic keyboard instrument 10 as shown in Figure 13.

[0048] In this way, the warp of the console panel 31 is corrected, the gap between the console panel 31 and the speaker cover 32 is made uniform in the key arrangement direction LR, and further the upper plate main body portion 31b1 of the console panel 31 and the upper surface of the speaker cover 32 are made into a substantially continuous flat surface, resulting in an attractive-looking electronic keyboard instrument 10.

[0049] Although the embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and various modifications can be made to the present invention. For example, the pin 51 and the pin insertion hole 55 may be arranged such that the pin insertion hole 55 is provided in the console panel 31, and the pin 51 is provided in the upper case 21. Similarly, the blade member 61 and the flat hole portion 65a may be arranged in the reversed manner.

[0050] According to the above embodiment of the present invention, the electronic keyboard instrument 10, which is an electronic device, has a top surface member 30, which is a mounting member, including a console panel 31, which is a first mounting member, having a blade member 61, which is a first male portion, protruding from the outer periphery in a first direction D1, and a speaker cover 32, which is a second mounting member, having a flat hole portion 65a, which is a first female portion corresponding to the blade member 61, and an instrument case 20 (upper case 21), which is a mounting receiving member to which the top surface member 30 is attached. The top surface member 30 includes either a pin 51, which is a second male portion extending in a second direction D2 different from the first direction D1, or a pin insertion hole 55, which is a second female portion into which the pin 51 is inserted, and the instrument case 20 (upper case 21) includes the other of the pin 51 and the pin insertion hole 55.

[0051] This allows the top member 30 to be accurately positioned relative to the upper case 21, while correcting any warping of the console panel 31 and optimizing the gap between the console panel 31 and the speaker cover 32. Therefore, the top member 30 can be satisfactorily fixed to the instrument case 20.

[0052] Moreover, the blade member 61 is a wide protruding piece protruding in the first direction D1, and the length in the width direction is longer than the length in the thickness direction. The flat hole portion 65a includes an elongated hole into which the blade member 61 is inserted, the length in the width direction being longer than the length in the thickness direction. This makes it possible to easily arrange the blade member 61 on the plate-shaped console panel 31 or the speaker cover 32 while ensuring the strength of the blade member 61.

[0053] Moreover, the upper surface member 30 (speaker cover 32) has a wall surface sliding portion 70 on the outer surface of the wall portion 32d which faces the inner surface of the wall portion 21b of the upper case 21. This makes it possible to adjust the gap between the console panel 31 and the speaker cover 32 as the pin 51 is inserted into the pin insertion hole 55.

[0054] Furthermore, the console panel 31 and the speaker cover 32 have an overlapping arrangement portion 75 where one of the console panel 31 and the speaker cover 32 overlaps the other, and the console panel 31 is provided with a rib portion 31b4 that receives the speaker cover 32. As a result, even if the speaker cover 32 is pressed, it can be received by the rib portion 31b4, so deformation of the speaker cover 32 and the console panel 31 can be reduced.

[0055] Furthermore, the speaker cover 32 has a recessed groove 32f provided along the front wall 32e in the vicinity of the front wall 32e, which is an edge portion facing the console panel 31. This allows efficient cutting of the fabric 33 after it has been wound in the manufacturing process, even if the height of the front wall 32e cannot be increased because it is an edge portion facing the console panel 31.

[0056] Additionally, the top surface member 30 and the instrument case 20 (upper case 21) are provided in an elongated shape, and the pins 51 and the pin insertion holes 55 are provided near both ends in the longitudinal direction, respectively. This makes it easier to correct warping of the console panel 31 of the top surface member 30, which is elongated, and allows the top surface member 30 to be positioned appropriately.

[0057] Further, the felt member 62, which is a cloth member, is attached to the flat surface of the blade member 61. This makes it possible to reduce the generation of abnormal noise caused by the blade member 61 colliding with the inside of the flat hole portion 65a even when the electronic device vibrates (for example, while the electronic keyboard instrument 10 is being played).

[0058] Moreover, the electronic keyboard instrument 10, which is an electronic device, has a keyboard 11. This makes it possible to provide an electronic keyboard instrument 10 in which the top surface member 30 is fixed to the instrument case 20 in an excellent manner.

[0059] In addition, the manufacturing method of the electronic keyboard instrument 10, which is an electronic device, includes fitting the vane member 61, which is a first male portion protruding in a first direction D1 from the outer periphery of the console panel 31, which is a first mounting member, into the flat hole portion 65a, which is a first female portion, of the speaker cover 32, which is a second mounting member. Then, the pin 51, which is a second male portion extending in a second direction D2 different from the first direction D1 provided on either the console panel 31 or the speaker cover 32, fits into the pin insertion hole 55, which is a second female portion, included in the instrument case 20, which is the mounting member. This adjusts the gap between the console panel 31 and the speaker cover 32, and allows the electronic keyboard instrument 10 to be manufactured with the top surface member 30 attached to the instrument case 20 in a good condition.

[0060] Furthermore, when the pin 51 fits into the pin insertion hole 55, the wall surface sliding portion 70 of the top surface member 30 comes into contact with the wall portion 21b of the upper case 21. This allows the top surface member 30 to be attached to the upper case 21 while being properly guided.

[0061] In addition, the gap between the console panel 31 and the speaker cover 32 is adjusted to be narrower after the wall surface sliding portion 70 comes into contact with the wall portion 21b compared to before the wall surface sliding portion 70 comes into contact with the wall portion 21b. As a result, even if the console panel 31 is injection molded so as to be curved in a bow shape when viewed from above, the gap between the console panel 31 and the speaker cover 32 is uniform from the center to both left and right ends, making it possible to manufacture an electronic keyboard instrument 10 with a good appearance.

[0062] Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
