[0014] By configuring the touch sensor without providing a space between the touch surface and the touch sensor, touch detection can be performed well. Therefore, the touch sensor of the conventional touch input device is firmly mounted by bonding or the like so as not to be peeled off from the glass substrate. However, when a touch sensor fails, it is not easy to replace only the touch sensor, and sometimes the glass substrate on which the touch sensor is mounted and the input device including the glass substrate must also be replaced.

[0015] The present disclosure relates to an input device, an electronic device, and an electronic keyboard musical instrument that have excellent repairability and are capable of good touch detection.

The left side L of the step portion 221c is open, and a protrusion 221c1 is provided at the left end of the rear side B of the step portion 221c. In addition, a threaded hole portion 225 is provided on the housing 220, and the threaded hole portion 225 has a threaded hole so as to protrude from the right side R of the rear end to the rear side B.

[0023] The lower end of the protruding plate 224b1 of the right side plate 224 is configured to have a gap between the upper surface of the lower surface plate of the main body shell 30 for isolating the vibration during sound production. In addition, the threaded hole portion 225 is fixed to the chassis (not shown) of the keyboard 20 fixed to the main body shell 30. In addition, the long hole 222b1 of the front plate 222 is engaged with the sheet metal member (not shown) fixed to the main body shell 30. In this way, the shell 220 is fixed to the main body shell 30.

[0024] A plurality of openings 2a (second openings) are provided on the first mounting surface 221a of the upper surface plate 221 along the front-to-back direction FB (the length direction of the upper surface plate 221). The opening 2a is a through hole in a substantially long rectangular shape with the left-right direction as the length direction. In the present embodiment, six openings 2a are provided. Between the openings 2a, openings 2b are provided at three locations, and an opening 2c in a long rectangular shape smaller than the opening 2a is provided at one location. The opening 2b is two small rectangular holes arranged side by side in the left-right direction LR. The configuration of the openings 2a, 2b, 2c of the housing 220 corresponds to the light-transmitting portions 11a, 11b, 11c of the panel 210. Therefore, the openings 2a, 2b, 2c are configured in the order of openings 2a, 2a, 2b, 2a, 2b, 2a, 2c, 2a, 2b, 2a, starting from the front side F.

[0025] like Figure 4 As shown, on the surface of the upper surface plate 221 on the opposite side of the first mounting surface 221a (i.e., the lower surface 221b of the upper surface plate 221), a total of four bosses 226 are arranged at two locations each on the front side F and the rear side B of the upper surface plate 221, and the bosses 226 are substantially rectangular shapes that are longer in the front-to-back direction FB. The bosses 226 are provided with female screws (fixing members). In addition, the tap screws as fastening members are fastened to the inner side of the bosses 226 while performing thread cutting, so that thread cutting is formed on the inner side of the bosses 226. A positioning pin 227 is provided between the two bosses 226 on the front side F and near the two bosses 226 on the rear side B. On the lower surface 221b near the base end of the left side plate 223, circular recesses 228 are provided on the front side F and the rear side B, respectively. On the lower surface 221b near the base end of the right side plate 224, long rectangular recesses 229 that are long in the front-to-back direction FB are provided on the front side F and the rear side B, respectively. A plurality of ribs 22A connected to the right side plate 224 are provided at the right R end edge of the lower surface 221b. Nine ribs 22A are provided between the two long rectangular recesses 229 at the front and rear ends. Two long protrusions 22C are provided in the up-down direction UL on the inner side surface corresponding to the protruding plate 224b1 of the right side plate 224. The protruding plate 224b1 is reinforced by the protrusions 22C to suppress deformation.

[0026] like Figure 3 As shown, the light diffuser 230 is provided in a substantially rectangular sheet shape that is long in the front-to-back direction FB and has the function of diffusing light. A circular hole 238 corresponding to the circular recess 228 of the housing 220 is provided at the front and rear of the left side of the light diffuser 230. In addition, a slit-shaped locking recess 234 is provided at the right side R near the front end of the light diffuser 230. A cut-out-shaped recess 235 is provided at the rear side B of the locking recess 234.

[0027] like Figure 3 and Figure 5 As shown, the touch detection substrate 240 is a substrate of a generally long rectangular shape that is longer in the front-to-back direction FB, and is made of an opaque material. The touch detection substrate 240 is provided with a plurality of openings 4a (first openings) that are penetrated in a generally long rectangular shape that is longer in the left-right direction LR. The openings 4a are provided along the front-to-back direction FB, and are provided at six locations in this embodiment. Between the openings 4a, openings 4b are provided at three locations, and an opening 4c of a long rectangular shape that is smaller than the opening 4a is provided at one location, and the opening 4b is a hole of two small long rectangles arranged side by side in the left-right direction LR. The configuration of the openings 4a, 4b, 4c of the touch detection substrate 240 corresponds to the light-transmitting portions 11a, 11b, 11c of the panel 210 and the openings 2a, 2b, 2c of the housing 220. Therefore, the openings 4a, 4b, 4c are configured in the order of openings 4a, 4a, 4b, 4a, 4b, 4a, 4c, 4a, 4b, 4a, from the front side F.

[0028] The outer periphery of the opening 4a on the upper surface 241 of the touch detection substrate 240 is provided with a substantially long rectangular ring shape. Figure 5 The touch pattern 243 is shown in the middle shaded area. The touch pattern 243 is a capacitive touch sensor and is provided on the periphery of each opening 4a by printing or the like. The touch pattern 243 can detect a change in capacitance inside the substantially long rectangular ring. That is, the touch pattern 243 detects a change in capacitance in the opening area of ​​the opening 4a (the area where the opening 4a is opened).

[0029] A circular through hole 248a is provided on the front side F of the left end of the touch detection substrate 240, and a long hole 248b is provided on the rear side B of the left end of the touch detection substrate 240. The hole 248a and the long hole 248b correspond to the circular recess 228 of the housing 220 and the hole 238 of the light diffusion sheet 230.

[0030] like Figure 3 and Figure 6 As shown in FIG. 1 , the reflector 250 is arranged in a substantially long rectangular shape that is long in the front-to-back direction FB. The reflector 250 has a substantially long rectangular plate-shaped reflector body 251. The front and rear ends of the reflector body 251 swell in the left-right direction LR and have four legs 256 that are formed into a crank shape facing downward. Each leg 256 is provided with a screw hole 256a for mounting, and the screw hole 256a is inserted into the screw member 25b (fastening member). The lower surface of the reflector body 251 is a second mounting surface 253.

[0031] The reflector body 251 is provided with a plurality of light reflecting areas 5a, 5b, and 5c. The light reflecting area 5a is a substantially long rectangular shape that is long in the left-right direction LR and is a quadrangular pyramid-shaped hole that is extended toward the upper surface 252 of the reflector body 251. In addition, the peripheral edge 5a1 of the opening of the light reflecting area 5a on the second mounting surface 253 side of the reflector body 251 is in the shape of a vertical wall (see Figure 8 The light reflection region 5b is a roughly long rectangular shape slightly longer in the front-to-back direction FB, and two quadrangular pyramid-shaped holes are arranged in parallel in the left-right direction LR so as to be expanded toward the upper surface 252 of the reflector body 251. The light reflection region 5c is a roughly long rectangular shape slightly smaller than the light reflection region 5a, and is a quadrangular pyramid-shaped hole arranged so as to be expanded toward the upper surface 252 of the reflector body 251.

[0032] Six light reflection areas 5a are provided in the front-to-back direction FB, three pairs of light reflection areas 5b are provided between two adjacent light reflection areas 5a, and one light reflection area 5c is provided between two adjacent light reflection areas 5a. The configuration of the light reflection areas 5a, 5b, 5c corresponds to the light-transmitting portions 11a, 11b, 11c of the panel 210, the openings 4a, 4b, 4c of the touch detection substrate 240, and the openings 2a, 2b, 2c of the housing 220. Therefore, the light reflection areas 5a, 5b, 5c are configured in the order of light reflection areas 5a, 5a, 5b, 5a, 5b, 5a, 5c, 5a, 5b, 5a from the front side F.

[0033] Positioning pins 258 are provided at the front and rear ends of the upper surface 252 of the reflector body 251 on the left side L of the portion that bulges to the left and right at the front and rear ends. Hook-shaped limiting portions 259 are provided at the front and rear ends of the upper surface 252 of the reflector body 251 on the right side R of the portion that bulges to the left and right at the front and rear ends. A locking protrusion 254 is provided in front of the limiting portion 259 on the front side F. A protruding plate portion 25A that protrudes in a tongue shape toward the front side F is provided at the approximate center of the left-right direction LR at the front end of the reflector body 251. A notched recess 257a is provided on the protruding plate portion 25A. A through circular hole 257b is provided at the approximate center of the left-right direction LR at the rear end of the reflector body 251.

[0034] On the right side R of the second mounting surface 253, positioning pins 25D protruding toward the lower side Lo are provided at the front and rear, respectively. The positioning pins 25D correspond to the front and rear holes 248a, the long hole 248b, the hole 238 of the light diffusion sheet 230, and the recess 228 of the housing 220 of the touch detection substrate 240. In addition, at the rear end of the reflector body 251, a long rectangular hole 254a that is long in the left-right direction LR and a recess 254b that is substantially at the center left edge in the front-back direction FB are provided. The hole 254a and the recess 254b are used to avoid interference with the input device 200 or other electronic components provided on the substrate.

[0035] The reflector 250 is integrally formed of a resin material. In this embodiment, the reflector 250 is made of a white resin material so that the light from the light emitting portion 6s of the light emitting regions 6a, 6b, 6c is easily reflected in the light reflecting regions 5a, 5b, 5c.

[0036] like Figure 3 As shown, the control substrate 260 is a substrate of a generally long rectangular shape that is longer in the front-to-back direction FB and is made of an opaque material. A plurality of light-emitting areas 6a, 6b, and 6c having a plurality of light-emitting portions 6s are provided on the control substrate 260. In the present embodiment, the light-emitting portion 6s is an LED. The light-emitting area 6a is configured in such a manner that three LEDs are arranged in parallel in the left-right direction LR, except for the second light-emitting area 6a1 from the front. The second light-emitting area 6a1 from the front is configured in such a manner that five LEDs are arranged in parallel in the left-right direction LR. The light-emitting area 6b is configured in such a manner that two LEDs are arranged in parallel in the left-right direction LR.

[0037] The configuration of the light-emitting areas 6a, 6b, and 6c corresponds to the light-transmitting portions 11a, 11b, and 11c of the panel 210, the light-reflecting areas 5a, 5b, and 5c, the openings 4a, 4b, and 4c of the touch detection substrate 240, and the openings 2a, 2b, and 2c of the housing 220. Therefore, the light-emitting areas 6a, 6b, and 6c are sequentially configured in the order of the light-emitting areas 6a, 6a1 (6a), 6b, 6a, 6b, 6a, 6c, 6a, 6b, and 6a from the front side F. In addition, the width (the length in the left-right direction LR) of the light-emitting areas 6a, 6b, and 6c at the left and right ends thereof is substantially the same. Therefore, the light-emitting area 6a1 configured with five LEDs has the smallest interval with the adjacent LEDs, and the light-emitting area 6b configured with two LEDs has the largest interval with the adjacent LEDs.

[0038] A long through hole 26D1 that is long in the front-to-back direction FB is provided on the front side F of the right side R of the control substrate 260, and a through circular hole 26D2 is provided on the rear side B. The long through hole 26D1 and the hole 26D2 correspond to the positioning pins 25D in front and back of the second mounting surface 253 of the reflector 250. In addition, an IC chip (not shown) that controls the lighting of the LEDs of the light-emitting areas 6a, 6b, and 6c is provided on the control substrate 260.

[0039] The panel 210 is mounted on the first mounting surface 221a of the housing 220. The edges of the front side, rear side, and right side R of the panel 210 are close to or contact the step portion 221c of the housing 220 and are positioned on the first mounting surface 221a. The panel 210 and the first mounting surface 221a can be mounted using an adhesive including a double-sided tape.

[0040] The touch detection substrate 240 is sandwiched between the lower surface 221b of the upper surface plate 221 opposite to the first mounting surface 221a of the housing 220 and the upper surface 252 of the reflector body 251 opposite to the second mounting surface 253 of the reflector 250. Specifically, the mounting is performed as follows.

[0041] The right edge of the touch detection substrate 240 is engaged with the limiting portion 259 of the reflector body 251 relative to the reflector 250, so that the movement of the touch detection substrate 240 in the up and down direction is limited. At the same time, on the touch detection substrate 240, the front and rear positioning pins 258 of the reflector 250 are respectively inserted into the front and rear holes 248a and the long hole 248b of the touch detection substrate 240. In this way, the touch detection substrate 240 is positioned relative to the reflector 250. The dimensional error between the positioning pins 258 is absorbed by the long hole 248b.

[0042] A light diffuser 230 is provided between the lower surface 221b of the housing 220 and the touch detection substrate 240. The positioning pins 258 of the reflector 250 are inserted into the holes 238 of the light diffuser 230. Since the light diffuser 230 does not require high-precision positioning, the positioning pins 258 are loosely embedded to avoid interference with the holes 238. In addition, the locking recess 234 of the light diffuser 230 is locked with the locking protrusion 254 of the reflector 250, so that the movement of the light diffuser 230 relative to the reflector 250 and the touch detection substrate 240 is restricted. The recess 235 of the light diffuser 230 prevents the light diffuser 230 from interfering with the limiting portion 259 on the front side F of the reflector 250. In addition, the light diffuser 230 can be omitted according to the diffusibility of the light emitted from the light emitting areas 6a, 6b, and 6c.

[0043] The control substrate 260 is mounted on the second mounting surface 253 of the reflector 250. At this time, the positioning pin 25D on the front side F of the reflector 250 is inserted into the long hole 26D1 on the front side F of the control substrate 260, and the positioning pin 25D on the rear side B of the reflector 250 is inserted into the hole 26D2 on the rear side B of the control substrate 260. In this way, the control substrate 260 is positioned relative to the reflector 250. An adhesive including a double-sided tape can be used to fix the control substrate 260 and the reflector 250.

[0044] like Figure 7 As shown, the reflector 250 is fixed relative to the housing 220 by screwing the screw member 25b (fastening member) into the boss 226 via the threaded hole 256a of the leg 256 of the reflector 250. Figure 3 , Figure 4 and Figure 6 As shown, when the reflector 250 is fixed to the shell 220, the cut-out recess 257a at the front end of the reflector 250 engages with the positioning pin 227 on the front side F of the shell 220, and the reflector 250 is positioned relative to the shell 220 by inserting the positioning pin 227 on the rear side B of the shell 220 into the hole 257b of the reflector 250.

[0045] In addition, interference between the positioning pin 258 of the reflector 250 and the upper surface plate 221 of the housing 220 is avoided by the recess 228 of the housing 220. Similarly, interference between the limiting portion 259 of the reflector 250 and the upper surface plate 221 of the housing 220 is avoided by the long rectangular recess 229 of the housing 220. In addition, the plurality of ribs 22A of the housing 220 are close to or in contact with the right edge end surface of the reflector body 251, and provide rigidity to the housing 220. Thus, when the user operates the touch switch, the plurality of ribs 22A provide a sense of rigidity.

[0046] Thus, when the input device 200 is assembled, the panel 210, the upper surface 221 of the housing 220, the touch detection substrate 240, the reflector 250, and the control substrate 260 are as shown in FIG. Figure 8Here, the light-emitting portion 6s of the LED as the light-emitting area 6a is arranged in the area of ​​the opening 4a of the touch detection substrate 240 (within the range of the opening 4a as viewed from the vertical upper side of the touch surface 211). In addition, the light-emitting portion 6s of the light-emitting area 6a is arranged corresponding to the light-reflecting area 5a of the reflector 250. In other words, the light-emitting portion 6s of the light-emitting area 6a is arranged in the area of ​​the opening of the light-reflecting area 5a of the second mounting surface 253 as the lower surface of the reflector body 251. Moreover, the opening 2a of the shell 220 (upper surface 221) is arranged in the area of ​​the opening 4a of the touch detection substrate 240. In other words, the opening 4a of the touch detection substrate 240 is set larger than the opening 2a of the shell 220, and the shell 220 (upper surface 221) is arranged directly above the touch pattern 243.

[0047] In the input device 200 configured in this manner, even if the touch pattern 243 of the touch detection substrate 240 fails, the touch detection substrate 240 can be easily removed by removing the reflector 250 fixed to the housing 220 by the screw member 25b (fastening member). That is, the housing and the reflector are detachably fixed by the screw member 25b (fastening member). In addition, since there is no air layer directly above the touch pattern 243, the lower surface 221b of the upper surface plate 221 of the housing 220 is close to or in contact with the touch pattern 243, so that the touch detection of the touch pattern 243 can be performed well.

[0048] Here, as described above, the lower surface of the panel 210 is painted black, but the area other than the area corresponding to the light-emitting areas 6a, 6b, 6c and the openings 4a, 4b, 4c, 2a, 2b, 2c is painted black so that the light from the light-emitting portion 6s of the light-emitting areas 6a, 6b, 6c can be visually confirmed. The portion of the panel 210 that is not painted black is the light-transmitting portions 11a, 11b, 11c that transmit light corresponding to the light-emitting areas 6a, 6b, 6c and the openings 4a, 4b, 4c, 2a, 2b, 2c. The light emitted by the light-emitting portion 6s is emitted to the outside through the openings 4a, 4b, 4c, the openings 2a, 2b, 2c, and further through the light-transmitting portions 11a, 11b, 11c.

[0049] More specifically, the light-transmitting portions 11a, 11b, and 11c are provided by printing or the like so that characters, symbols, and the like indicating the contents operated by touch operation can be recognized by the transmitted light. Specifically, the surroundings of the characters or the like are printed in a dark color in a slightly light-shielding manner, and the characters or the like are set to be transparent. Figure 8As shown in (b), the range of the light-transmitting portion 11a on which characters are recorded is defined as the display range T. Moreover, the center CT in the left-right direction LR of the display range T is set to the right of the center CH in the left-right direction LR of the openings 2a, 4a and the light-reflecting area 5a. That is, the center CT is offset relative to the center CH.

[0050] The input device 200 is arranged on the left key cover 38L on the left side L. Therefore, when the player who is located at the approximate center in the left-right direction LR of the keyboard 20 observes the input device 200, as shown by the line of sight E, the display range T is observed from the upper right. Assuming that the center CT of the display range T is aligned with the center CH of the openings 2a, 4a and the light reflection area 5a, the left end T3 of the display range T is close to the edge of the left side L of the opening 2a. Then, as shown by the line of sight E, when observed from the perspective of the player, the vicinity of the left end T3 of the display range T is located closer to the left side L than the edge of the left side L of the opening 2a, so the light from the light-emitting area 6a cannot be transmitted, and the characters close to the left end of the characters recorded in the display range T appear to be missing. Therefore, the center CT of the display range T is arranged on the right side R of the center CH of the openings 2a, 4a and the light reflection area 5a. In addition, since the line of sight E does not overlap with the right side R of the opening 2a, the characters on the right end of the display range T can be visually recognized even if they are close to the edge of the opening 2a. That is, as shown in FIG. Figure 2 As shown in the block diagram of , the area TL on the left side L of the display range T and the area TR on the right side R of the display range T are set to TR<TL.

[0051] According to the above-mentioned embodiment of the present invention, the input device 200 includes: a touch detection substrate 240 having an opening 4a as a first opening, and a touch pattern 243 is provided on the outer periphery of the opening 4a; a control substrate 260 having a light emitting portion 6s; a reflector 250 provided between the touch detection substrate 240 and the control substrate 260, and having a light reflection area 5a configured corresponding to the light emitting portion 6s; a panel 210 including a touch surface 211; a housing 220 having an opening 2a as a second opening, and the panel 210 is mounted; the light emitted by the light emitting portion 6s is emitted to the outside through the opening 4a and the opening 2a, and the housing 220 and the reflector 250 are fixed in a detachable manner by a screw member 25b as a fastening member. That is, the opening area of ​​the second opening (opening 2a) is smaller than the opening area of ​​the first opening (opening 4a).

[0052] Thus, since the touch detection substrate 240 is sandwiched between the lower surface 221b of the upper surface plate 221 of the housing 220 and the upper surface 252 of the reflector 250, even in the case of a touch pattern failure, only the reflector 250 can be removed from the housing 220 to easily replace only the touch detection substrate 240. Furthermore, since the lower surface 221b of the upper surface plate 221 of the housing 220 is arranged just above the touch pattern, an air layer is excluded, and touch detection can be performed well.

[0053] Furthermore, a light diffusion sheet 230 is provided between the housing 220 and the touch detection substrate 240. Thus, even when a semiconductor light emitting element such as an LED is used as the light emitting unit 6s, diffused light can be irradiated to the light transmitting unit 11a of the panel 210, and the light transmitting unit 11a can be uniformly irradiated.

[0054] In addition, the reflector 250 and the touch detection substrate 240 are positioned by the positioning pins 258. Therefore, once the position of the reflector 250 relative to the housing 220 is determined, the touch pattern 243 can be easily positioned relative to the panel 210.

[0055] The touch surface 211 is provided with a display range T of characters, symbols, etc. arranged in the region of the opening 2a. This facilitates setting work and improves the design of the appearance by emitting light from the operation touch panel.

[0056] The light emitted by the light emitting unit is released to the outside through the first opening and the second opening. The center CT of the display range T is offset from the center CH of the left-right direction LR of the opening 2a, etc. Thus, even if the input device 200 is observed from an oblique direction, the end of the characters, etc. recorded in the display range T can be clearly observed without being missed.

[0057] In addition, the electronic keyboard instrument 1 as an electronic device is provided with an input device 200 on the key cover. Thus, it is possible to provide an electronic keyboard instrument 1 (electronic musical instrument) that has high repairability and has an input device 200 that can perform touch detection well. In addition, the electronic device has the input device disclosed in the present invention, a control unit, and an output device that outputs according to the input from the input device.

In addition, the equivalent scope of the changes made according to the description in the scope of the claims that are irrelevant to the main purpose of the present invention is also included in the technical scope of the present invention.
