As described later, a part of the music stand 40 is accommodated in this accommodation space SP when the angle of the music stand 40 is adjusted. In addition, as described later, the music stand 40 is brought into abutment with the protruding flange 50 a 3 and the protruding plate 50 b 1 when the music stand 40 is at an angle substantially upright relative to the front upper panel 36F. Here, a plurality of ribs 54 extending in an up-down direction in a rib-like shape are provided at predetermined intervals in the left-right direction on the rear surface 50 bwhich forms a surface facing the accommodation space SP. Each rib 54 is provided in such a manner as to support the protruding flange 50 a 3 to thereby reinforce the protruding flange 50 a 3 in the up-down direction.As shown in FIG. 3, the main fitting fitting 60 includes a first plate (a first plate component) 61 having a substantially rectangular plate shape, a second plate (a second plate component) 62 having a substantially rectangular plate shape, and a third plate (a third plate component) 63 having a substantially rectangular plate shape. An end portion of the second plate 62 is rotatably connected to an end portion of the first plate 61 by a first hinge H 1. The other end portion (the end opposite to the side connected to the first plate 61) of the second plate 62 is rotatably connected to an end portion of the third plate 63 via a second hinge H 2. The main fitting fitting 60 is attached to the front upper panel 36F as a result of the first plate 61 being screwed thereto in such a posture that the first hinge H 1 and the second hinge H 2 rotate about an axis extending along the left-right direction (the X-axis direction). As viewed from one side, the main fitting fitting 60 takes a substantially triangular shape as a result of the second plate 62 being rotated upward and the third plate 63 being rotated toward the first plate 61.As shown in FIG. 4, five screw holes (hereinafter referred to as "first screw holes 61 a") having the same shape are provided at predetermined intervals in the left-right direction while being arranged in two rows in a substantially central portion of the first plate 61. A pair of first pawls 61 bare provided at a predetermined interval in the left-right direction at a portion of the first plate 61 that is close to the first hinge H 1. These first pawls 61 bare each formed in a pawl shape by being bent outward (downward) at substantially right angles from a plate surface of the first plate 61. In addition, a first engagement zone 61 c 1, a second engagement zone 61 c 2, and a third engagement zone 61 c 3 are provided at predetermined intervals in the front-rear direction in this order from the other end portion of the first plate 61 at a portion of the first plate 61 opposite to the portion facing the first hinge H 1. These engaging zones 61 c 1, 61 c 2, 61 c 3 are each formed in a claw shape by being bent inward (upward) at substantially right angles from the plate surface of the first plate 61.Each first claw 61 bis bent into a claw shape in such a manner that both surfaces of a portion thereof bent at substantially right angles are oriented in the left-right direction. The first engagement zone 61 c 1, the second engagement zone 61 c 2, and the third engagement zone 61 c 3 are each provided in such a manner as to extend longitudinally in the left-right direction, and are each bent in a claw shape in such a manner that both surfaces of a portion thereof bent at substantially right angles are oriented in the front-rear direction. The other end portion of the third plate 63 (an end portion of the third plate 63 opposite to the end portion at which the third plate 63 is connected to the second plate 62) is configured to be abutted from a front side with proximal end portions of the engagement zones 61 c 1, 61 c 2, 61 c 3 bent into the claw shape for engagement therewith. The main fitting fitting 60 is held in such a manner that the other end portion of the third plate 63 in the front-rear direction is fixed and the second plate 62 is inclined with respect to the front upper panel 36F as a result of the other end portion of the third plate 63 being engaged with the engagement zones 61 c 1, 61 c 2, 61 c 3.Three screw holes (hereinafter referred to as "second screw holes 62 a 1") having the same shape are provided at predetermined intervals in the left-right direction while being arranged in a single row in a portion of the second plate 62 that is close to the first hinge H 1. Three screw holes (hereinafter referred to as "third screw holes 62 a 2") having the same shape are provided at predetermined intervals in the left-right direction while being arranged in a single row in a portion of the second plate 62 that is close to the second hinge H 2. A pair of second pawls 62 bare provided at a predetermined interval in the left-right direction in a substantially central portion of the second plate 62. These second pawls 62 bare each formed in a pawl shape by being bent outward (forward) at substantially right angles from a plate surface of the second plate 62. The second claws 62 bare each bent into the claw shape in such a manner that both surfaces of a portion bent at substantially right angles are oriented in the left-right direction.Three protrusions 63 aare provided at predetermined intervals in the left-right direction on a plate surface of the third plate 63 (a plate surface oriented toward the first plate 61 when the third plate 63 is rotated toward the first plate 61) in such a manner as to protrude toward the first plate 61 while extending from the one end portion to the other end portion of the third plate 63. Here, as shown in FIG. 8, these protrusions 63 aare arranged so as not to collide with the first engagement zone 61 c 1 when the second plate 62 and the third plate 63 are folded down toward the first plate 61 without the second hinge H 2 being rotated.As shown in FIG. 3, each auxiliary fitting fitting 70 includes a fourth plate (a fourth plate component) 71 having a substantially rectangular shape and a fifth plate (a fifth plate component) 72 having a substantially rectangular shape. An end portion of the fourth plate 71 is rotatably connected to an end portion of the fifth plate 72 by a third hinge H 3. Each auxiliary adjustment fitting 70 is attached to the front upper panel 36F as a result of the fourth plate 71 being screwed thereto in such a posture that the third hinge H 3 rotates about an axis extending along the left-right direction (the X-axis direction). The music stand 40 is attached to each auxiliary adjustment bracket 70 as a result of the music stand 40 being screwed to the fifth plate 72 of the auxiliary adjustment bracket 70. Here, the third hinge H 3 is formed of a torque hinge, so that the fifth plate 72 is configured to be stopped at an arbitrary position to which the fifth plate 72 is rotated with respect to the fourth plate 71 by the third hinge H 3.Next, with reference to FIG. 5, a manner of attaching the main fitting fitting 60 to the front upper panel 36F will be described. The main fitting fitting 60 is attached to the front upper panel 36F in such a state that the first plate 61 is positioned with respect to the front upper panel 36F. That is, positioning holes (not shown) with which the first claws 61 bare engaged are provided in a portion of the front upper panel 36F to which the first plate 61 is attached in such a manner as to correspond to the first claws 61 b, so that the first plate 61 is positioned on the front upper panel 36F as a result of the first claws 61 bbeing engaged with the corresponding positioning holes (see FIG. 5 ). Thereafter, the first plate 61 is attached to the front upper panel 36F by being screwed thereto with first attachment bolts S 1 inserted into the corresponding first screw holes 61 a.Here, in the main fitting fitting 60, the first screw holes 61 aare provided at a position away from the first hinge H 1. Consequently, in an attachment operation of the main fitting fitting 60, when the first plate 61 is screwed to the front upper panel 36F after the first plate 61 is positioned with respect to the front upper panel 36F, a screw driving tool is allowed to easily pass over the first screw holes 61 a, thereby facilitating a screw driving operation.Next, with reference to FIG. 5, a manner of attaching the music stand 40 to the main adjustment bracket 60 will be described. The music stand 40 is attached to the second plate 62 of the main adjustment bracket 60 by being screwed thereto. The second plate 62 is attached to the back surface 40 bof the music stand 40 in such a state that the second plate 62 is positioned with respect to the music stand 40. That is, positioning holes (not shown) with which the second claws 62 bare engaged are provided in a portion of the rear surface 40 bof the music stand 40 to which the second plate 62 is attached in such a manner as to correspond to the second claws 62 b, so that the second plate 62 is positioned on the rear surface 40 bof the music stand 40 as a result of the second claws 62 bbeing engaged with the corresponding positioning holes (see FIG. 5 ). Thereafter, the second plate 62 is attached to the rear surface 40 bof the music stand 40 by being screwed thereto with second attachment screws S 2 inserted into the corresponding second screw holes 62 a 1 and third attachment screws S 3 inserted into the corresponding third screw holes 62 a 2.When the music rack 40 is attached to the front upper panel 36F by the main adjustment bracket 60 and the auxiliary adjustment bracket 70 in the above-described manner, the inclination angle of the music rack 40 can be adjusted in accordance with players by changing the engagement position of the third plate 63 of the main adjustment bracket 60 from the engagement zones 61 c 1, 61 c 2, 61 c 3 and rotating the respective fifth plates 72 of the auxiliary adjustment brackets 70. Here, when the music stand 40 is inclined at a certain angle with respect to the front upper panel 36F, at least a part of the lower end portion (on the front surface 40 a) of the music stand 40 is accommodated in the accommodation space SP (see FIGS. 6A to 7B ).In addition, as shown in FIG. 8, the rack 40 with the main adjustment bracket 60 can be folded down rearward by rotating the first hinge H 1 in such a manner that the second plate 62 and the third plate 63 are folded down toward the first plate 61 without rotating the second hinge H 2. When this occurs, as described above, the protrusions 63 aof the third plate 63 do not collide with the first engagement zone 61 c 1, which allows the first hinge H 1 to be rotated to such an extent that the first engagement zone 61 c 1 abuts against a plate surface of the third plate 63, whereby the rack 40 can be folded down to such an extent that the rack 40 becomes parallel to the front upper panel 36F. When the rack 40 is folded down in such a state, the lower end portion of the rack 40 moves away from the accommodation space SP.Next, referring to FIGS. 6A to 7B, a concrete adjustment method for adjusting the inclination angle of the music stand 40 with respect to the front upper panel 36F will be described. Here, in the following description, only the operation of the main fitting fitting 60 will be described, and with respect to each auxiliary fitting 70, it is assumed that the fifth plate 72 is rotated and held in accordance with the inclination angle of the second plate 62 of the main fitting fitting 60. The second plate 62 and the third plate 63 are rotated from the state shown in FIG. 8 in which the rack 40 is folded down, and the rack 40 is caused to rise, after which the other end portion of the third plate 63 is engaged with the first engagement zone 61 c 1 as shown in FIG. 6A. As a result, the music stand 40 can be supported by the main adjustment bracket 60 in such a state that the music stand 40 is left standing with an inclination angle θ 1 of the music stand 40 with respect to the front upper panel 36F set to, for example, 56.6 degrees.In addition, the lower end portion on the front surface 40 aof the music stand 40 penetrates into the accommodation space SP at a predetermined inclination angle resulting while the music stand 40 is caused to rise from the state shown in FIG. 8 in which the music stand 40 is folded down to the state shown in FIG. 6A in which the music stand 40 is at the inclination angle θ 1. Then, when the inclination angle of the music stand 40 remains equal to or greater than the predetermined inclination angle, the lower end portion on the front surface 40 aof the music stand 40 remains within the accommodation space SP. As a result, adjustment of the inclination angle of the music stand 40 is permitted while the music stand 40 is close to the music holder 50, as in the present embodiment. When the note stand 40 is at the inclination angle θ 1, as shown in FIG. 6A, a gap G 1 defined between the front surface 40 aof the note stand 40 and the distal end portion of the protruding flange 50 a 3 of the note holder 50 is set to, for example, 4.6 mm.In the state shown in FIG. 6A, although an excessive downward force F 1 is applied to a position on the front surface 40 aof the music stand 40 that is higher than the main adjustment bracket 60, detachment of the music stand 40 from the main adjustment bracket 60 is limited because the portion of the second plate 62 that is close to the first hinge H 1 is screwed to the music stand 40 with the second attachment screws S 2.The note stand 40 is caused to rise further from the state shown in FIG. 6A by rotating the second plate 62 and the third plate 63, and the other end portion of the third plate 63 is engaged with the second engagement zone 61 c 2 as shown in FIG. 6B. As a result, the music stand 40 can be supported by the main adjustment bracket 60 in such a state that the music stand 40 is left standing with an inclination angle θ 2 of the music stand 40 with respect to the front upper panel 36F set to, for example, 64.6 degrees. In this state, the distance of a gap G 2 defined between the front surface 40 aof the note stand 40 and the distal end portion of the protruding flange 50 a 3 of the note holder 50 is set to, for example, 3.5 mm. This results in a state in which the music stand 40 comes closer to the protruding flange 50 a 3 than the state shown in FIG. 6A (a state closer to the upright position of the music stand 40).The note stand 40 is caused to rise further from the state shown in FIG. 6B by rotating the second plate 62 and the third plate 63, and the other end portion of the third plate 63 is engaged with the third engagement zone 61 c 3 as shown in FIG. 7A. As a result, the music stand 40 can be supported by the main adjustment bracket 60 in such a state that the music stand 40 is left standing with an inclination angle θ 3 of the music stand 40 with respect to the front upper panel 36F set to, for example, 72.6 degrees. In this state, the distance of a gap G 3 defined between the front surface 40 aof the note stand 40 and the distal end portion of the protruding flange 50 a 3 of the note holder 50 is set to, for example, 2.2 mm. This results in a state in which the music stand 40 comes closer to the protruding flange 50 a 3 than the state shown in FIG. 6B (a state closer to the upright position of the music stand 40).The music stand 40 is caused to rise still further from a state shown in FIG. 7A by removing the third plate 63 from the third engagement zone 61 c 3 and rotating the second plate 62 and the third plate 63, and the music stand 40 is caused to rise in a substantially upright position with respect to the front upper panel 36F until the inclination angle of the music stand 40 with respect to the front upper panel 36F becomes set to an inclination angle θ 4 of, for example, 82 degrees as shown in FIG. 7B. Then, a lower end of the music rack 40 is abutted with a plate surface of the second protrusion 50 b 1 extending in the plate shape, thereby preventing the music rack 40 from inclining further forward. That is, the second protrusion 50 b 1 functions as a stopper for preventing the music stand 40 from excessively inclining forward.In the state shown in FIG. 7B in which the music stand 40 is in a substantially upright position relative to the front upper panel 36F (the state in which the lower end of the music stand 40 abuts against the second protrusion 50 b 1), the distance of a gap G 4 defined between the front surface 40 aof the music stand 40 and the distal end portion of the protruding flange 50 a 3 of the music holder 50 (see an enlarged view E 1 shown in FIG. 7B ) is set to, for example, 0.3 mm. In this way, the music stand 40 is prevented from tilting further forward in such a state that the very small gap is defined between the music stand 40 and the protruding flange 50 a 3 (in other words, the state in which the front surface 40 aof the music stand 40 is closer to the protruding flange 50 a 3), whereby the music stand 40 is prevented from being abutted with the protruding flange 50 a 3, and this prevents the front surface 40 aof the music stand 40 from being scratched or dent by the protruding flange 50 a 3.In addition, although an excessive force is applied to the music stand 40 to thereby bring the music stand 40 into collision with the distal end portion of the protruding flange 50 a 3, when the music stand 40 is caused to rise to the state where the music stand 40 is in a substantially upright position as shown in FIG. 7B, since the distal end portion of the protruding flange 50 a 3 is chamfered, scratching or denting of the front surface 40 aof the music stand 40 is limited by the protruding flange 50 a 3. Here, in the state shown in FIG. 7B, although an excessive upward forward force F 2 is applied to a position on the rear surface 40 bof the music stand 40 that is farther upward than the main adjustment bracket 60, a distance of the music stand 40 from the main adjustment bracket 60 is limited because the portion of the second plate 62 that is close to the second hinge H 2 is screwed to the music stand 40 with the third attachment screws S 3.Thus, as described above, with the electronic keyboard instrument 1, the inclination angle of the music rack 40 can be adjusted to the inclination angles θ1, θ2, θ3at which the other end portion of the third plate 63 is respectively engaged with the engagement zones 61 c 1, 61 c 2, 61 c 3, whereby the music rack 40 can be supported by the main adjustment bracket 60 in these individual circumstances. When the inclination angle of the music rack 40 is adjusted as described above, at least a part of the lower end portion of the music rack enters the accommodation space, thereby preventing the music rack from colliding with the music rack. As a result, the note stand can be provided close to the note holder, whereby the space on the front upper panel 36F can be saved.
