The substantially overall of the face exposed of top covered by the cap assembly 26 of artificial leather etc..Although the 1st housing 21 and the 2nd housing 22 are logical
Fastened by screw is crossed, but the screw is covered without showing in appearance by cap assembly 26.
In the structure shown here, when using music stand 20 and music score pressing element 10 to load music score 103, user makes keyboard
Lid 101 is open mode, and then makes music stand 20 be open mode.Then, user to turn to necessary music score pressing element 10 vertical
Play position.For example, in the case of it is desirable that keeping a music score 103 in the left and right directions center of keyboard instrument 100, as long as making four
Two, center in individual music score pressing element 10 is erected.Or, it is desirable that the feelings for keeping two music score 103 with arranging in left and right
Under condition, it is more appropriate that four music score pressing elements 10 are erected.In addition, it is desirable that keeping finding pleasure in only in bass side, only in treble side
In the case of spectrum 103, it is also contemplated that the mode for erecting two music score pressing elements 10 of two of left side or right side.In a word, stand
Rise music score pressing element 10 pressing component 12 ensure that behind (face opposed with the back side of cover of keyboard 101) area it is more wide
Wealthy, compared with the music score pressing element obliquely erected of conventional type, the area that can be contacted with music score 103 is larger.Pressing component 12
Music score 103 is pressed from front.
However, in set-up positions, bed flat position in music score pressing element 10, each tabular surface of holding section 14,15 is with being crimped
Portion 24,25 is crimped.Make music score pressing element 10 from set-up positions to lie low direction rotate when, the 1st holding section 14 tabular surface from
While opening the 1st and be crimped portion 24, the corner 14a (Fig. 3) of the 1st holding section 14 is connected to the 1st and is crimped portion 24.If further making
Music score pressing element 10 is rotated to the direction that lies low, then corner 14a and the 1st is crimped the sliding contact of portion 24, then, and corner 14a also leaves
1st is crimped portion 24, moves to the stage for rotating midway.Here, it is right because the 1st holding section 14 with the 1st is crimped crimping for portion 24
In that will produce resistance from set-up positions to the rotation in the direction that lies low, particularly, in corner, 14a is crimped portion 24 with the 1st and supported
Connect during being then departed from, produce maximum resistance.Therefore, rotation initial stage of set-up positions, production are departed from music score pressing element 10
The peak value of raw resistance.
On the other hand, when music score pressing element 10 is rotated between set-up positions and bed flat position, by axis mechanism portion 11
Outer peripheral face 11a and the 1st is crimped which discontiguous stroke (Fig. 4 (a)) that portion 24 and the 2nd is crimped portion 25.Therefore,
The maximum of the resistance produced when music score pressing element 10 departs from set-up positions, than rotating the minimum for the resistance that midway is produced
Value is big.
In this regard, can also assert in the same manner when making music score pressing element 10 be rotated from the direction that lies low to set-up positions.That is,
While the tabular surface of 2 holding sections 15 leaves the 2nd and is crimped portion 25, the corner 15a (Fig. 3) of the 2nd holding section 15 is connected to the 2nd quilt
Pressure contact portion 25.Afterwards, after corner 15a and the 2nd are crimped the sliding contact of portion 25, it is crimped portion 25 from the 2nd and leaves, moves to and turn
The stage of dynamic midway.Therefore, rotation initial stage of bed flat position is departed from music score pressing element 10, the peak value of resistance is produced.In music score
Pressing element 10 departs from the maximum of the resistance produced during bed flat position, bigger than in the minimum value for rotating the resistance that midway is produced.
So, the maximum ratio of the resistance produced when music score pressing element 10 departs from set-up positions or bed flat position is turning
The minimum value for the resistance that dynamic midway is produced is big, therefore the stable posture of the music score pressing element 10 of set-up positions, bed flat position.And
And, in music score pressing element 10 from when reaching set-up positions or bed flat position in the stage for rotating midway, also pass through and produce resistance
The stage of peak value.Thereby, it is possible to obtain restraining sense (Japanese in the firm place of set-up positions, bed flat position：The sense of Festival degree), can
Realize along with being comfortably caught in sense (Japanese：The sense of Network リ ッ Network) rotating operation.Further, since in the rotation of music score pressing element 10
On the way, music score pressing element 10 is nearly free from friction or resistance, it is ensured that the smoothly rotation of music score pressing element 10 and durability.
, can in addition, by forming blank part 11b between holding section 14,15, it is easy in the radial direction bend holding section 14,15
Play the pressing force of appropriateness.Moreover, structure can be simplified.
As shown in Fig. 4 (b), in bed flat position, music score pressing element 10 is in the range of the thickness T1 of music stand 20, not from pleasure
Music rack 20 is protruded.In addition, in bed flat position, the face as upside of the pressing component 12 of music score pressing element 10 is upper with music stand 20
Surface can also turn into a face.In addition, the thickness T2 of the pressing component 12 of music score pressing element 10 is the thickness T1 of music stand 20
Less than half.Thereby, it is possible to maintain the rigidity and thinness of music stand 20.Particularly, it is easy to avoid the dorsal part in music stand 20
(bottom surface when using) shows screw, can avoid degraded appearance.
Fig. 6 (a), (b) are to close the schematic diagram near the keyboard KB in the state of cover of keyboard 101.Due to pressing component
12 is thin, not thick thus, it is possible to which music stand 20 is also configured as.Therefore, as shown in Fig. 6 (a), the state of music stand 20 is being closed
Under, even if close key disk cover 101, music stand 20 is also without interference with keyboard KB.In the present embodiment, further by music score pressure
Projecting height H of the pressing component 12 away from music stand 20 of the set-up positions of tool 10 is set as, even if forgetting to close music score pressing element
10 and the ground close key disk cover 101 of music stand 20, music stand 20 is also without interference with keyboard KB.That is, projecting height H (Fig. 3) is set
It is set to following height：Even if music score pressing element 10 is carried out rotating operation to music stand 20 with keeping set-up positions, and then as pressing
The leading section of splenium part 12 is connected to the state of cover of keyboard 101, and cover of keyboard 101 is also turned off, and music stand 20 will not also connect
Touch in keyboard KB (Fig. 6 (b)).Thus, even if unintentionally being operated, the dry of keyboard KB and cover of keyboard 101 can also be avoided
Disturb.
According to present embodiment, center of rotation C is located at player's side end 20a of the music stand 20 when using.In addition, happy
Spectrum pressing element 10 is rotated freely centered on the almost parallel center of rotation C of the orientation with key, is taken when in use
Set-up positions, pressing component 12 presses music score 103 from front.That is, the diameter parallel with the rotary shaft of music score pressing element is in front and back
To conventional structure it is different.Hereby it is possible to ensure it is longer to the distance of rotary shaft 102 from center of rotation C, can will be orthogonal to turn
The length (height) of the pressing component 12 of music score pressing element 10 on dynamic center C direction is also set to longer.Also, due to from pleasure
The reaction forces that bear of spectrum 103 be with center of rotation C orthogonal directions and and nonparallel direction, therefore be pressed without excessively thickening
Splenium part 12, the limitation of the thickness of music stand 20 is also less.In addition, the length of the music score pressing element 10 on left and right directions can be free
Ground is designed, and can press music score 103 in wider scope if longer.Therefore, it is possible to improve the design of music stand 20 certainly
By spending, and ensure that the contact area of pressing component 12 and music score 103 is larger.
According to present embodiment, relative to music score when music score pressing element 10 departs from set-up positions and when departing from bed flat position

Midway produces larger resistance friction, it is ensured that smoothly rotates, and can suppress the deterioration of abrasion, the drop of durability
It is low.Further, since retainer portion 23 is located at into music stand 20, therefore music score pressing element 10, energy are born relative to excessive rotatory force
Enough improve durability.Further, since music stand 20 is rotatably disposed in the back side of cover of keyboard 101, therefore, it is possible in keyboard
The back side mounting music score 103 of lid 101, can also apply to erect type piano.
However, the conventional bar-shaped music score pressing element obliquely erected is almost only with leading section in the way of the points of proximity are contacted
Press music score.On the other hand, in the present embodiment, pressing component 12 is also longer in the lateral direction, left and right directions which
Individual position can play the function of pressing music score 103.Thus, it is also possible to realize with a music score pressing element 10 while pressing two
Application method as music score 103.For example, by being located at the right-hand member of the music score 103 in left side and the left end of the music score 103 on right side
The left and right directions center of one pressing component 12, so as to play the function of the single page of two music score 103 of pressing.If lengthening pressing
The length of the left and right directions of part 12, it becomes possible to fully realize this point.Therefore, by setting three music score pressing elements 10, energy
It is enough to press two music score 103 simultaneously.Such application method is extremely difficult in conventional type.
In addition, for set-up positions, the viewpoint of the stable posture of bed flat position of music score pressing element 10 is made, it is also contemplated that such as
Under.First, the maximum ratio of the resistance produced when music score pressing element 10 departs from set-up positions or bed flat position is in rotation
The minimum value for the resistance that way is produced is big.Therefore, rotated between music score pressing element 10 is opened in set-up positions and bed flat position
