In this case, as shown in FIGS. 3 to 5, the fixing portion 27 and the attachment portion 28 are elongated along the arrangement direction of the white keys 7 a.

  Further, as shown in FIG. 4, the attachment portion 28 is inclined toward the rear side (right side in FIG. 4) of the white key 7a by a predetermined angle (for example, approximately 80 degrees) with respect to the fixed portion 27 by the connecting portion 29. It is fixed in the state. On the front surface (left side surface in FIG. 4) of the inclined mounting portion 28, the first substrate 25 is mounted with screws 30. The screw 30 is configured to be attached to the screw 26 fixing the fixing portion 27 in a state where the position is shifted in the arrangement direction of the white keys 7a.

On the upper front surface (left side surface in FIG. 6) of the plurality of protrusions 37, black key light emitting elements 38 for irradiating the front side of each black key 7b are provided.

  In this case, each of the white key light emitting element 32 and the black key light emitting element 38 is a side light emitting diode which is formed in a substantially rectangular parallelepiped chip shape and emits light only from the upper surface which is one side surface thereof. Since the light emitting elements 32 and 38 are formed in a substantially rectangular parallelepiped chip shape, as shown in FIGS. 2 and 3, the rear surface (right side surface in FIG. 2) has the first and second substrates 25. , 33 are mounted in a planar manner in a state of being in close contact with each upper front surface (left side surface in FIG. 2) of each protrusion 31 and 37 and being electrically connected with solder or the like.

  As a result, when the light emitting element 32 for the white key emits light from the upper surface which is one side surface thereof, as shown in FIG. 2, the light is irradiated to the inside of the front side of the white key 7a. A part of the white key 7a is transmitted so that the front side of the white key 7a is illuminated. Similarly to the white key light-emitting element 32, the black key light-emitting element 38 emits light from the upper surface, which is one side surface thereof, and as shown in FIG. 2, the light enters the front side of the black key 7b. A part of the irradiated light is transmitted through the black key 7b so that the front side of the black key 7b is illuminated.

Next, a case where the white key light emitting element 32 is assembled to the keyboard chassis 6 will be described.
In this case, as shown in FIG. 4, first, the light emitting elements 32 are respectively attached to the plurality of protrusions 31 of the white key first substrate 25, and the first substrate 25 is attached to the attachment portion 28 of the substrate attachment member 24. It is arranged on the front surface and attached with screws 30. Thereafter, the fixing portion 27 of the board mounting member 24 is attached to the keyboard chassis 6 by the screw 26.

  At this time, as shown in FIG. 5, the mounting position of the screw 26 for mounting the fixing portion 27 to the keyboard chassis 6 and the mounting position of the screw 30 for mounting the first substrate 25 to the mounting portion 28 are the arrangement direction of the white keys 7a. , The screw 30 with the first substrate 25 attached to the attachment portion 28 does not interfere with the screw 26 for attaching the fixing portion 27 to the keyboard chassis 6 from above the keyboard chassis 6 with a tool such as a screwdriver. Can be tightened.

  As a result, as shown in FIG. 4, the mounting portion 28 of the board mounting member 24 stands on the keyboard chassis 6 with a predetermined angle (for example, approximately 80 degrees) toward the rear (right side in FIG. The one board 25 is erected and attached in a state of being inclined toward the rear (right side in FIG. 4) of the keyboard chassis 6 in the same manner as the attachment portion 28.

  In this state, a plurality of keys 7 are attached to the key support portion 17 of the keyboard chassis 6. At this time, as shown in FIGS. 2 and 3, the plurality of protrusions 31 of the first substrate 25 provided with the light emitting elements 32 are relatively inserted into the respective white keys 7a in a non-contact state. Let As a result, the light emitting elements 32 provided on the respective protrusions 31 of the first substrate 25 are arranged corresponding to the lower side of the white key 7a.

Next, the operation of such a keyboard instrument will be described.
When playing with this keyboard instrument, when each key 7 is depressed in accordance with the performance, the light emitting elements 32 and 38 corresponding to the key 7 to be depressed are caused to emit light one after another. The keys 7 can be illuminated sequentially. For example, when the key 7 to be pressed is one of a plurality of white keys 7a, when the light emitting element 32 corresponding to the white key 7a is caused to emit light, the light is emitted to the front side inside the white key 7a, A part of the irradiated light passes through the white key 7a, so that the front side of the white key 7a can be illuminated.

  Further, when the key 7 to be pressed is one of the plurality of black keys 7b, when the light emitting element 38 corresponding to the black key 7b is caused to emit light, the light is irradiated to the front side inside the black key 7b, When a part of the irradiated light passes through the black key 7b, the front side of the black key 7b can be illuminated. As a result, the keys 7 to be depressed can be sequentially illuminated according to the performance, so that even if the performer is a beginner, the performance can be performed satisfactorily.

  Furthermore, in this keyboard instrument, when a performer performs a performance by pressing a plurality of keys 7, the key 7 pressed according to the performance is illuminated by the corresponding light emitting elements 32 and 38. Thus, the performer can confirm which key 7 is pressed, and thereby, it can be determined whether the key 7 is correctly pressed according to the performance.

  By the way, in such a keyboard instrument, since the length and shape of the plurality of keys 7 differ depending on the size and shape of the product, the inclination angle of the mounting portion 28 is set, for example, approximately according to the size and shape of the product. By setting any of 80 degrees, approximately 60 degrees, and approximately 90 degrees, it is possible to optimize the light irradiation region in which the light emitting element 32 emits light to the white key 7a.

  That is, when the board mounting member 24 having an inclination angle of the mounting portion 28 of approximately 80 degrees is used, the first substrate 25 is substantially moved according to the inclination of the mounting portion 28 of the board mounting member 24 as shown in FIG. By tilting at an angle of 80 degrees, the light emitted from the light emitting element 32 can be irradiated to a position near the middle portion of the white key 7a located on the front side (left side in FIG. 8) of the black key 7b.

  Further, when the substrate mounting member 24 having the inclination angle of the mounting portion 28 of approximately 60 degrees is used, the first substrate 25 is approximately moved according to the inclination of the mounting portion 28 of the substrate mounting member 24 as shown in FIG. By tilting at an angle of 60 degrees, the light emitted from the light emitting element 32 is placed at a position near the rear side (near the right side in FIG. 9) of the white key 7a located on the front side (left side in FIG. 9) of the black key 7b. Can be irradiated.

  Furthermore, when the board mounting member 24 with the inclination angle of the mounting portion 28 being approximately 90 degrees is used, as shown in FIG. 10, the first substrate 25 is moved substantially according to the inclination of the mounting portion 28 of the board mounting member 24. By tilting at an angle of 90 degrees, the light emitted from the light emitting element 32 is located near the front side (near the left side in FIG. 10) of the white key 7a located on the front side (left side in FIG. 10) of the black key 7b. Can be irradiated.

  As described above, according to this keyboard instrument, when the plurality of light emitting elements 32 are assembled to the keyboard chassis 6, the plurality of light emitting elements 32 are attached to the protrusions 31 of the first substrate 25 for white keys. The board 25 is attached to the attachment portion 28 of the board attachment member 24 with screws 30, and the fixing portion 27 of the board attachment member 24 is attached to the keyboard chassis 6 with screws 26, whereby the first substrate 25 is raised with respect to the keyboard chassis 6. In this state, the first board 25 can be securely and firmly fixed to the keyboard chassis 6 by the board mounting member 24.

  In this case, by attaching the first substrate 25 in a standing state with respect to the keyboard chassis 6, the light emitting elements 32 can be mounted on the keyboard chassis 6 without having to place the plurality of light emitting elements 32 on the first substrate 25. Can be provided upright. That is, since the plurality of light emitting elements 32 can be provided without standing on the first substrate 25, each light emitting element 32 can be stably placed without using a holding member for preventing the light emitting elements 32 from falling. It can be securely fixed to each protrusion 31 of one substrate 25.

  Further, when a plurality of white keys 7a having optical transparency are attached to the keyboard chassis 6 so as to be rotatable in the vertical direction, the plurality of protrusions 31 of the first substrate 25 are not contacted with each other inside the plurality of white keys 7a. By inserting in a state, the plurality of light emitting elements 32 can be arranged accurately and satisfactorily under the white keys 7a. Thereby, it is possible to suppress the light emitted from each light emitting element 32 from leaking to the adjacent white key 7a by the first substrate 25 and each protrusion 31 thereof, and only the white key 7a to be pressed is good. Can shine.

  In this case, since the mounting portion 28 of the board mounting member 24 stands up at a predetermined angle, the first board 25 can be tilted and attached to the keyboard chassis 6 by the mounting section 28. Therefore, the light irradiation area of the light emitting element 32 with respect to the white key 7a can be selected according to the inclination angle of the mounting portion 28, and the light irradiation of the light emitting element 32 with respect to the white key 7a according to the inclination angle of the mounting portion 28. In addition to being able to optimize the area, the installation location of the first board mounting portion 11 for attaching the board mounting member 24 to the keyboard chassis 6 is not limited, and the degree of freedom of the installation location of the first board mounting portion 11 is increased. be able to.

  As described above, this keyboard instrument has a simple structure and can be easily assembled, so that the productivity is high and mass production can be achieved. In addition, the projection of the first board 25 inserted into the white key 7a can be achieved. The light emitting element 32 can be reliably and firmly fixed in a stable state by the portion 31, thereby preventing the first substrate 25 on which the light emitting element 32 is mounted from falling off even when subjected to an impact such as dropping. Therefore, a thing with high impact resistance can be obtained. In addition, the light emitting element 32 can be accurately and satisfactorily disposed below the white key 7a by the protrusion 31 of the first substrate 25, and light emitted from the light emitting element 32 leaks to the adjacent white key 7a. Can be suppressed.

  In this case, the light emitting element 32 is formed in a substantially rectangular parallelepiped chip shape, and is a side light emitting diode that emits light from the upper surface that is one side surface thereof. The surface (right side in FIG. 2) is securely fixed in a state where it is brought into close contact with the upper front surface (left side in FIG. 2) of the protrusion 31 provided on the first substrate 25 by plane mounting and is electrically connected with solder or the like. can do.

  Therefore, the light emitting element 32 can be securely attached to each protrusion 31 of the first substrate 25 in a stable state, and the light emitting element 32 is attached to the upper front surface of each protrusion 35 of the first substrate 25. As a result, when each light emitting element 32 emits light, the light can be reliably irradiated to the inside of the front side of the white key 7a, so that the protruding portion 31 prevents the emitted light from leaking to the adjacent white key 7a. And the front side of the white key 7a can be shined well.

And a regulating piece 44b that regulates these, and these are integrally formed. As shown in FIG. 12, the angle regulating member 44 is provided at both ends of the board mounting member 40 (only the right end is shown in FIG. 12).

  In addition, since the angle regulating member 44 has different lengths and shapes of the plurality of keys 7 depending on the size and shape of the product, the inclination angle of the mounting portion 42 is regulated according to the size and shape of the product. A plurality of types are prepared so as to optimize the light irradiation area of the light emitting element 32 with respect to the white key 7a. That is, the angle restricting member 44 has three kinds of inclination angles of the restricting piece 44b of approximately 80 degrees, approximately 60 degrees, and approximately 90 degrees, and the white key is the same as in the first embodiment shown in FIGS. The light irradiation area of the light emitting element 32 with respect to 7a can be selected.

  For example, the angle restricting member 44 whose inclination angle of the restricting piece 44b is approximately 80 degrees restricts the inclination of the mounting portion 42 of the substrate mounting member 40 to approximately 80 degrees and tilts the first substrate 25 at an angle of approximately 80 degrees. Thus, as shown in FIG. 8, the light emitted from the light emitting element 32 is configured to irradiate a portion near the middle portion of the white key 7a located in front of the black key 7b (left side in FIG. 8). ing.

  Further, the angle restricting member 44 whose inclination angle of the restricting piece 44b is approximately 60 degrees restricts the inclination of the mounting portion 42 of the substrate mounting member 40 to approximately 60 degrees and tilts the first substrate 25 at an angle of approximately 60 degrees. Accordingly, as shown in FIG. 9, the light emitted from the light emitting element 32 is located near the rear side (near the right side in FIG. 9) of the white key 7a located on the front side (left side in FIG. 91) of the black key 7b. It is comprised so that it may irradiate.

  Furthermore, the angle regulating member 44 whose tilt angle of the regulating piece 44b is approximately 90 degrees regulates the tilt of the mounting portion 42 of the board mounting member 40 to approximately 90 degrees and tilts the first substrate 25 at an angle of approximately 90 degrees. Thus, as shown in FIG. 10, the light emitted from the light emitting element 32 is approximately near the front side (near the left side in FIG. 10) of the white key 7a located on the front side (left side in FIG. 10) of the black key 7b. It is comprised so that a location may be irradiated.

  According to such a keyboard instrument, in addition to the same effects as in the first embodiment, the connection portion 43 of the board attachment member 40 is formed so that the inclination angle of the attachment portion 42 with respect to the fixed portion 41 can be adjusted. The connecting portion 43 can adjust the inclination angle of the attachment portion 42 to adjust the inclination angle of the first substrate 25 attached to the attachment portion 42, so that the light emitting element 32 attached to the first substrate 25 can emit light. Can be adjusted to an optimum state.

  In this case, since a plurality of types of angle regulating members 44 that regulate the angle of the mounting portion 42 with respect to the fixed portion 41 of the board mounting member 40 are provided, the inclination of the mounting portion 42 is set to a predetermined angle by the plurality of types of angle regulating members 44. Thus, the tilt angle of the first substrate 25 can be stabilized and fixed.

  That is, each of the plurality of types of angle restricting members 44 includes a fixing piece 44 a fixed on the fixing portion 41 by the screw 26 and a restricting piece 44 b that restricts the inclination of the attaching portion 42. Depending on the inclination of the mounting portion 42, the inclination angle of the restricting piece 44b is different. For example, the plurality of angle restricting members 44 have three kinds of inclination angles of the restricting pieces 44b of approximately 80 degrees, approximately 60 degrees, and approximately 90 degrees, as in the first embodiment shown in FIGS. The white key 7a can be selected according to the light irradiation region where the light emitting element 32 emits light.

  For example, the angle restricting member 44 whose inclination angle of the restricting piece 44b is approximately 80 degrees restricts the inclination of the mounting portion 42 of the substrate mounting member 40 to approximately 80 degrees and tilts the first substrate 25 at an angle of approximately 80 degrees. As a result, as shown in FIG. 8, the light emitted from the light emitting element 32 can be applied to a portion near the middle portion of the white key 7a located on the front side (left side in FIG. 8) of the black key 7b.

  Further, the angle restricting member 44 whose inclination angle of the restricting piece 44b is approximately 60 degrees restricts the inclination of the mounting portion 42 of the substrate mounting member 40 to approximately 60 degrees and tilts the first substrate 25 at an angle of approximately 60 degrees. As shown in FIG. 9, the light emitted from the light emitting element 32 is located near the rear side (near the right side in FIG. 9) of the white key 7a located on the front side (left side in FIG. 9) of the black key 7b. Can be irradiated.

  Furthermore, the angle regulating member 44 whose tilt angle of the regulating piece 44b is approximately 90 degrees regulates the tilt of the mounting portion 42 of the board mounting member 40 to approximately 90 degrees and tilts the first substrate 25 at an angle of approximately 90 degrees. Thus, as shown in FIG. 10, the light emitted from the light emitting element 32 is approximately near the front side (near the left side in FIG. 10) of the white key 7a located on the front side (left side in FIG. 10) of the black key 7b. It is possible to irradiate the spot.
