When opening/closing keyboard cap unit UNT was in buttoned-up status, keypad portion KB was covered by keyboard lid 60.Under semi-open state or full open position, keypad portion KB opens wide, so can carry out the operation of performance.Therefore, not only when keyboard lid 60 and header board 65 are in open mode, can carry out the operation of performance, and also can carry out the operation of performance and if only if keyboard lid 60 is opened when header board 65 is closed.

The 65 couples of players of header board that are in closed condition are covered the space of the rear portion KBa top of keypad portion KB, yet when this header board 65 was in open mode, it made the space of rear portion KBa top open wide the player.When the space open of rear portion KBa top, panel part 10 is visible and can operate for the player.Especially, send forward from the space of opening wide of the top of rear portion KBa from the sound of loudspeaker 12, sound can effectively be sent thus.

As Fig. 2 and shown in Figure 5, travelling arm 42 is made up of forearm 43, postbrachium 44 and rack member 40.Forearm 43 and postbrachium 44 are made of metal and form one.Selectively, they can be made respectively, can be fixed together afterwards.Rack member 40 is fixed to the lower surface of travelling arm 42, so that extend to postbrachium 44 places from forearm 43.The lower surface of rack member 40 is formed with tooth bar 41 on its whole length.

As shown in Figure 3, guiding installation component 30 is fixed to the inner surface of the side plate 23 on the proceeds posterolateral of transposition arm 22.This guiding installation component 30 is mounted with slide-and-guide main body 31 (equally referring to Fig. 2 and Fig. 5).As Fig. 2 and shown in Figure 5, slide-and-guide main body 31 has a pair of guide rail 36 that extends parallel to each other along fore-and-aft direction up and down.Middle ways 32 is connected to guide rail 36 slidably by a plurality of not shown cylindrical bearings that go out.In the present embodiment, use to have the assembling parts that middle ways 32 has been assembled to slide-and-guide main body 31, its commercial be the obtainable linear slide plate 4045F of the manufacturing of THK company (for example, by).

Ways 32 in the middle of the postbrachium 44 of travelling arm 42 is slidably connected to.In the process that fore-and-aft direction slides, this centre ways 32 slides on a half-distance of the distance that travelling arm 42 slides at travelling arm 42, and this travelling arm 42 can slide stably with respect to slide-and-guide main body 31 thus.

As Fig. 2 and shown in Figure 5, stopper element 34 is placed in the rear portion of slide-and-guide main body 31, and buffer component 35 is placed in the front portion of stopper element 34.When the rear end of postbrachium 44 touched buffer component 35, the position of travelling arm 42 rear ends was limited (referring to Fig. 8) in sliding process.One stopper element also is provided, not shown, the position of its limit slippage arm 42 front end in sliding process.Fig. 2 and Fig. 5 show the state of travelling arm 42 in front position.In the left side of musical instrument main body 101, the travelling arm on the right side of travelling arm 42 and related elements and musical instrument main body 101 and element symmetry.

In addition, as Fig. 2, Fig. 3 and shown in Figure 5, blocking lever fixator 37 is fixed to side plate 23, and an end of blocking lever 38 is rotatably fixing by blocking lever fixator 37.Rotatably be placed in the end of blocking lever 38 with the pinion wheel 39 of tooth bar 41 engagement of rack member 40.Has same mechanism with the left plate of right side symmetry.Therefore, left and right sides pinion wheel 39 is with blocking lever 38 rotations.When travelling arm 42 was slided on fore-and-aft direction by guide rail 36 guiding, because the engagement of left and right sides pinion wheel 39 and corresponding tooth bar 41, arm 42 mobile phase amount of movement together always horizontally slipped.As a result, travelling arm 42 is prevented from rolling and jolting in the horizontal direction, and slides reposefully on fore-and-aft direction, and is simultaneously always stable on posture.

As shown in Figures 2 and 3, transposition arm 22 within it portion have gathering sill (displacement guiding) 45.Gathering sill 45 by will be by metal etc. that make and individual member that have groove fixedly row transposition arm 22 be provided.Selectively, gathering sill can directly form in transposition arm 22.As shown in Figure 2, gathering sill 45 is made up of continuous arch section 45a that forms and straight part 45b (fixator or lengthwise movement targeting part).This arch section 45a forms along the circumference that with pivot 67 is the center, and straight part 45b forms along fore-and-aft direction.In addition, as Fig. 2 and shown in Figure 5, the ways 33 that extends continuously with the straight part 45b of gathering sill 45 is fixed to the inboard of keyboard base 21.In the left side of musical instrument main body 101, also provide gathering sill 45 and ways 33 with formed gathering sill in musical instrument main body 101 right sides and ways symmetry.

The engaging pin 69 and the gathering sill 45 of header board 65 mesh slidably.When header board 65 was in closed condition, engaging pin 69 meshed (referring to Fig. 2) with the front end of arch section 45a.When header board 65 rotated around pivot 67, left and right sides engaging pin 69 was directed to along the arch section 45a of gathering sill 45 separately, and header board 65 can stably rotate thus.When header board 65 is in open mode, the junction of engaging pin 69 between arch section 45a and straight part 45b.

The straight part 45b of gathering sill 45 has when travelling arm 42 slides and the upper surface of engaging pin 69 engagements, rotates on the direction of closing to stop header board 65, thereby header board 65 is maintained open mode.The lower surface 33a of ways 33 also meshes with engaging pin 69, reaches similar effect.The upright position of the lower surface 33a of ways 33 is approximately identical with the upper surface of straight part 45b.As a result, when travelling arm 42 slided, engaging pin 69 was transmitted between the lower surface 33a of straight part 45b and ways 33 reposefully.

When opening/closing keyboard cap unit UNT was fully closed, keyboard instrument 100 was configured to have and the very similar outward appearance of acoustic piano.Even when being in semi-open state in this unit, it also has the similar outward appearance of opening with the keyboard lid of acoustic piano.The position height that is positioned at the panel part 10 at the header board 65 Lower Half rears that are in closed condition approximates the height of the Lower Half of header board 65 greatly.Therefore, when opening/closing keyboard cap unit UNT was in full open position, 10 couples of players of panel part were visible and exercisable.As a result, this musical instrument has the outward appearance of suitable electric keyboard instrument.In Fig. 2, symbol P2 represents the extreme higher position of panel part 10.When main switch is switched on and opening/closing keyboard cap unit UNT when placing semi-open state, this musical instrument operation is so that acoustic piano sound is default sound, and the performance of similar acoustic piano can begin and need not to carry out other operation thus.Selectively, this musical instrument can be configured to main switch and open automatically by opening keyboard lid 60 simply, can begin to have the performance of acoustic piano sound thus immediately.

Next, opening/closing and the operation of holding keyboard cap unit UNT will be explained.

Fig. 6 illustrates the right view that opening/closing keyboard cap unit UNT is in the keyboard lid structure of semi-open state; Fig. 7 is the right view of keyboard lid structure, and in this keyboard lid, the opening/closing keyboard cap unit of being arranged to full open position is received in the musical instrument main body 101; Fig. 8 illustrates to be in the right view that opening/closing keyboard cap unit has been received into the keyboard lid structure of the state in the musical instrument main body fully.

In buttoned-up status as shown in Figure 5, when keyboard lid anterior 62 is booked when being lifted by its handle portion (not shown), this keyboard lid 60 is around pivot 63 rotations, keyboard lid 60 is brought into folded state like this, in this folded state, it is in the face of header board 65, as shown in Figure 6.Afterwards, keyboard lid anterior 62 is further folded, and reaches semi-open state as shown in Figure 2 thus, and wherein keyboard lid front portion 62, keyboard lid 60 and header board 65 are folded up on another by one.In this state, keypad portion KB can be operated and be used for playing.

In off position, because the gravitational equilibrium of header board 65 self, it is pushed counterclockwise around pivot 67 in Fig. 2.In addition, header board 65 covers 60 with keyboard and combines, so the weight of keyboard lid 60 is applied to first end 65a.Therefore, header board 65 is applied in a rotating torque around pivot 67, and described pivot is motion counterclockwise in Fig. 2.As a result, header board 65 is pushed from the direction that closed condition changes open mode in prevention.Therefore, when carrying out the operation of raising keyboard lid 60 simply by the general fashion of catching keyboard lid anterior 62, have only keyboard lid 60 to be rotated, header board 65 is not rotated.This allows the steady opening operation of keyboard lid 60.

When the holding that recess 64 (referring to Fig. 2) is booked of the first end 60a of keyboard lid 60 and when keyboard lid 60 was elevated, keyboard lid 60 and header board 65 rotated around the pivot 67 of header board together.At that time, engaging pin 69 slides along the arch section 45a of gathering sill 45.As a result, opening/closing keyboard cap unit UNT is brought into full open position as shown in Figure 7.Especially, opening/closing keyboard cap unit UNT is brought into one " lifting state ", in this state its be fold and horizontal-extending.In this state, keypad portion KB can be operated and be used for playing.

In the process that header board 65 is rotated, engaging pin 69 meshes with the arch section 45a of gathering sill 45.Therefore, by this arch section 45a, engaging pin 69 is limited in the motion of fore-and-aft direction.Because this reason, in the process of header board 65 rotational motions, travelling arm 42 is prevented from moving backward, and travelling arm 42 is maintained at front position as a result, and header board 65 can be opened reposefully thus.

After opening/closing keyboard cap unit UNT is elevated, soon, is applied to the power of holding on the recess 64 a little and is acting on the direction backward on the opening/closing keyboard cap unit UNT usually.Because this power, the engagement of the arch section 45a of engaging pin 69 and gathering sill 45 changes the engagement of part 45b straight with it into.When engaging pin 69 meshed with straight part 45b, opening/closing keyboard cap unit UNT no longer closed.Therefore, it keeps full open position, and state although it is so is still unsettled.Even engaging pin 69 does not mesh with straight part 45b, because moment of torsion suppresses unit 66, opening/closing keyboard cap unit UNT also is prevented from suddenly closing.

When opening/closing keyboard cap unit UNT was promoted gently backward, travelling arm 42 slided backward by the guide rail 36 of middle ways 32 with respect to guide body 31.This opening/closing keyboard cap unit UNT also slides backward, and keeps the engaging pin 69 that meshes with straight part 45b and lift state constant.In the process of sliding, engaging pin 69 breaks away from the lower surface 33a engagement of meshing and being brought into ways 33 with straight part 45b, yet, keep the state of raising and continue to slide.

As mentioned above, in the process of sliding, because the engagement between left and right sides pinion wheel 39 and tooth bar 41, the arm 42 that horizontally slips slides reposefully.By travelling arm 42 is slided, in abutting connection with buffer component 35, this opening/closing keyboard cap unit UNT and travelling arm 42 are received in the musical instrument main body 101 (referring to Fig. 8) up to its rear end.Keypad portion KB can be operated in as shown in Figure 7 state and any stage between the state as shown in Figure 8 and be used for playing.

In order to close above-mentioned opening/closing keyboard cap unit UNT, make as shown in Figure 8 be in hold completion status opening/closing keyboard cap unit UNT to front slide, it is drawn out thus.Afterwards, make this unit slide into front position, the engaging pin 69 and the arch section 45a of gathering sill 45 are meshed, so opening/closing keyboard cap unit UNT is owing to the weight of himself is slowly rotated on closing direction, to enter semi-open state.After this, keyboard lid 60 is closed, and keyboard lid anterior 62 is opened, and returns to buttoned-up status thus.

When opening/closing keyboard cap unit UNT is in full open position (lifting state), the extreme lower position of this opening/closing keyboard cap unit UNT (being the position of the first end 60a of P1 represents among Fig. 7 keyboard lid 60) is kept above the extreme higher position P2 (referring to Fig. 2) of panel part 10, and far above the extreme lower position of the opening/closing keyboard cap unit UNT that is in semi-open state (it is identical with the position P1 that keyboard shown in Figure 2 covers 60 first end 60a).As a result, keep it to raise never interference surface board 10 of state opening/closing keyboard cap unit UNT constant and that move at fore-and-aft direction.

Next, the structure of the front portion of panel part 10 will be explained.Fig. 9 is the amplification sectional view that the front portion of panel part 10 is shown.The forward part of this panel part 10 has the lid member 70 of the width of the KB of overlay keyboard portion.Figure 10 is the partial plan layout of this lid member.

As shown in Figure 9, supporting member 74 is fixed to the bottom (it also is anterior) of panel part 10, and the lid main body 71 of lid member 70 is fixed to the top and the supporting member 74 of the bottom of panel part 10.The leading section of lid main body 71 is bent downwardly, and therefore hides the rear of keypad portion KB.Lid member 70 is placed on the rear portion KBa top of keypad portion KB fully.Especially, from fore-and-aft direction, lid member 70 is on rear end 25a on the black key 25 and the Bai Jian 24 between the 24a of rear end.When opening/closing keyboard cap unit UNT was in full open position, the upper surface of lid member 70 was visible fully to the player.When opening/closing keyboard cap unit UNT is in semi-open state, the slit between the bottom by opening/closing keyboard cap unit UNT and the last rear end 25a of black key 25, the major part of lid member 70 is visible.Especially, because opening/closing keyboard cap unit UNT has the recess of holding 64, so lid member 70 is seen in the scope of holding recess 64 is provided easily.

As Fig. 9 and shown in Figure 10, lid main body 71 side within it is formed with the lens component of being made by transparent resin or analog 72, with corresponding each white key 24 and black key 25.Each lens component 72 has rear end surface 72c, downwards and be positioned at anterior inclined surface 72b, be positioned on the inclined surface 72b and as the upper surface 72a of light-emitting area.This lid main body 71 has the upper surface that is formed with open-work 71a on it, with corresponding each lens component 72.The upper surface 72a of each lens component 72 is positioned at corresponding open-work 71a.In lid main body 71, sheet element (semi-transparent part) 73 is fixed on the whole width that covers main body 71 to cover open-work 71a.The upper surface 72a of lens component 72 is set up approaching and faces sheet element 73.In the bottom of panel part 10, LED 75 is configured to the rear end surface 72c near lens component 72, and corresponding each lens component 72.

Each LED 75 sends the light of predetermined luminance.When LED 75 sends the light time, this light that sends enters into the rear end surface 72c of corresponding lens component 72, shown in arrow among Fig. 9, and the inside of scioptics member 72, by the inner reflection of inclined surface 72b, and from upper surface 72a outgoing.

Sheet element 73 is made by translucent component.Especially, sheet element 73 is made by such material: when corresponding LED 75 was luminous, the light by sheet element 73 (from the light of the upper surface 72a outgoing of lens component 72) was visible; When LED 75 was not luminous, lens component 72 and LED 75 were hidden by sheet element 73 and are sightless.More particularly, can adopt material, as disclosed in Japanese Patent No. 3149107 with the raw material that acts on key.For example, sheet element is by by the base resin of the transparency, as melanic colored plain and have the material that the light scattering medium of light scattering ability forms and make.This sheet element 73 on color without limits.Consider the light emissive porwer of LED 75, be used to make surface color, optical transparency and the light scattering degree of the material of sheet element 73, be adjusted by the composition of determining pigment and will being comprised in the light scattering medium in the material, to satisfy the material properties of above-mentioned expectation.

Though undeclared, keyboard instrument 100 provide the independent operation that is used to detect white key 24 and black key 25 key sensor, the storage part that is used to store the automatic playing data, tone generative circuit, be used for the CPU or the like of comprehensive control of keyboard instrument 100.LED 75 is used to play.For example, under manual performance pattern, when the power that is not less than predetermined dynamics when corresponding key 24 or 25 was pressed, each LED 75 sent light.Under the automatic playing pattern, independent LED 75 sends light according to the automatic playing data, provides so-called performance auxiliary thus.

In the time can carrying out performance, lid member 70 is always visible for the player.On the other hand, when LED 75 was not luminous, lid member 70 was identified as trim or analog individually.Therefore, the existence of lens component 72 and LED 75 is never recognized.Especially, promptly being used in operating under the condition that opening/closing keyboard cap unit UNT is in semi-open state of performance is performed, the existence of lens component 72 is not recognized that musical performance can be performed by the keyboard instrument that has similar acoustic piano outward appearance thus yet.

When lens component 72, LED 75 etc. should be used to play when auxiliary etc., opening/closing keyboard cap unit UNT is placed in full open position, and the part of the open-work 71 that can form sheet element 73 from correspondence is seen the light that sends from lens component 72 easily thus.In addition, at that time, panel part 10 appears at the top of the rear portion KBa of keypad portion KB, opens wide towards the player, and keyboard instrument can be operated the performance that is used for based on electronic musical instrument without difficulty.

Can be provided for detecting the detector of the opening and closing state of opening/closing keyboard cap unit UNT, and LED 75 can be prevented from sending light unlimitedly under semi-open state.In other words, the lighting function of LED 75 only just is allowed under full open position.For such setting, even when the luminous mode of carrying out with button is set, the user only need set opening/closing keyboard cap unit UNT and be in semi-open state, just can carry out the performance operation that is used for similar acoustic piano, need not to stop the operation of lighting function.

According to present embodiment, make opening/closing keyboard cap unit UNT be in semi-open state by simply opening keyboard lid 60, can carry out the operation that is used to play that has similar acoustic piano outward appearance.Cover 60 by opening header board 65 and keyboard together, thereby make this unit be in full open position, the rear portion KBa superjacent air space of the KB of companion keyboard portion keeps opening wide, and the operation that is used to play can be performed.In addition, because have that the panel part 10 of electronic musical instrument function element is set under full open position the player is to open and present exercisable part, so not only the acoustic emission efficient (referring to Fig. 2) of loudspeaker 12 can be modified, and be used for also being performed without difficulty based on the operation that electronic musical instrument is played.In other words, when musical performance, the inside that can select musical instrument main body 101 is covered still the player player is opened wide, and this makes and can optionally carry out with the musical performance of similar acoustic piano outward appearance or based on the musical performance of electronic musical instrument.

According to present embodiment, by remaining on the state of raising (referring to Fig. 2) at backward direction slip travelling arm 42 and with keyboard lid 60 and header board 65, opening/closing keyboard cap unit UNT can be received in the musical instrument main body 101.When carrying out musical performance, be possible thereby opening/closing keyboard cap unit UNT is received into do not interfere in the musical instrument main body 101 rear that is positioned at keypad portion KB and the space of top, thereby guarantee that the above-mentioned space of mentioning provides a parts installing space.Do not have in the installing space of adverse effect in this opening, can place the panel part 10 that is mounted with music instruments function element keyboard cap unit UNT.Therefore, can save the space of musical instrument main body 101, make simultaneously can optionally to have the musical performance of similar acoustic piano outward appearance or to carry out musical performance based on electronic musical instrument.In musical performance, the opening/closing keyboard cap unit UNT that this is received does not have to constitute the obstacle to eyes, and good displaying is provided.

Because engaging pin 69 is by the arch section 45a guiding (referring to Fig. 2) of gathering sill 45, so the rotational motion of header board 65 is stable when header board 65 rotates around pivot 67.In the process that header board 65 is rotated, engaging pin 69 keeps engagement with the arch section 45a of gathering sill 45, therefore stops travelling arm 42 to move (referring to Fig. 2) backward.As a result, the opening operation of header board 65 and opening/closing keyboard cap unit UNT's raises operation and can stably carry out.

When opening/closing keyboard cap unit UNT was in the state of opening fully, the engagement of the straight part 45b that this state of opening fully can be by engaging pin 69 and gathering sill 45 was kept.This makes the state that the space of the rear portion KBa top be easy to keep keypad portion KB is opened wide the player.Because even the state of opening fully when making opening/closing keyboard cap unit UNT move up in front and back with travelling arm 42 is also kept, there is no need so support above-mentioned opening/closing keyboard cap unit UNT in sliding process, this makes and is easy to carry out the operation that is used to slide.

In addition, because the arch section 45a of gathering sill 45 and straight part 45b form continuously, therefore raise operation and the slide of opening/closing keyboard cap unit UNT can be continuous and stably, and the result opens with keyboard at the keyboard lid to cover improvement operability when holding.

When opening/closing keyboard cap unit UNT was in semi-open state, because the gravity of the gravity of header board 65 self and keyboard lid 60, header board 65 was applied in a rotating torque around pivot 67, and this rotating torque is applied on the counter clockwise direction among Fig. 2.In other words, this turning moment act on the opposing header board 65 be converted on the direction of open mode from closed condition.As a result, when keyboard lid 60 is caused when opening/closing keyboard cap unit UNT is in semi-open state when opening, header board 65 is suppressed to open on the direction by the operation of opening the keyboard lid and rotates, and this makes and is easy to carry out the operation of only opening the keyboard lid.

According to present embodiment, only send the light time at LED 75, the player can see the light that sends from arbitrary LED 75 by the sheet element 73 of lid member 70, therefore, when the operation that is used to play, can optionally carry out the performance that the existence of lighting function do not recognized or carry out the luminous performance of being recognized.When opening/closing keyboard cap unit UNT was in semi-open state and carries out musical performance, if LED 75 is not luminous, the existence of lighting means was not recognized so, and this makes to carry out with the outward appearance of similar acoustic piano and plays.

Adopt the vitrina that allows the light from lens component 72 to pass through because cover the sheet element 73 of the open-work 71a of main body 71, therefore make separately with a plurality of sheet elements and be used for open-work 71a, compare thereby satisfy above-mentioned specific demand, can make sheet element 73 with low cost.

In the present embodiment, because the engagement between the engaging pin 69 of the straight part 45b of gathering sill 45 and header board 65, the semi-open state of opening/closing keyboard cap unit UNT is kept.Yet this is not restrictive.Figure 11 A illustrates the partial side view that gathering sill 45 changes.Shown in the example of Figure 11 A, can provide the elastic component of making by metal or analog 46 as fixator, this elastic component 46 is located at the junction between the contiguous arch section 45a and straight part 45b on the upper surface of gathering sill 45.

This elastic component 46 is designed to be projected into and withdraws from arch section 45a.Especially, when elastic component 46 was in free state, it was projected into the inside of the arch section 45a shown in Figure 11 A, and when it was pressed by the inside of arch section 45a, this elastic component 46 outwards withdrawed from.When header board 65 is in open mode so that engaging pin 69 is when arriving the rear portion of arch section 45a and getting over elastic component 46, this engaging pin 69 is seized by elastic component 46.As a result, even openhanded opening, header board 65 can not rotate yet, and thus opening/closing keyboard cap unit UNT is maintained semi-open state.

From the angle of simplified structure, can not be provided for the mechanism that travelling arm 42 is slided in the present embodiment.Opening/closing keyboard cap unit UNT can be configured to only be transformed into full open position from buttoned-up status.In this case, make header board 65 be in the mechanism of open mode,, can adopt the rotation of header board to support by the engagement between the arch section 45a of pivot 67 or engaging pin 69 and gathering sill 45 as being used to.Just, in the present invention, engaging pin 69 and gathering sill 45 are used for the sliding motion of auxiliary travelling arm 42 and the state of header board 65 changes, because for the present invention, the two is optional, so it can be removed.Under the situation of the pivot 67 that does not have to be used for header board, there is no need to make the arch section 45a of gathering sill 45 to form circle, as long as it forms a kind of header board 65 and utilizes it to be directed into the shape of open mode.Even when removing the pivot 67 that is used for header board or arch section 45a, preferably provide a mechanism that is used to keep the full open position of opening/closing keyboard cap unit UNT, as elastic component 46.By under the pivot 67 rotatably supported situations, preferably the correct position in musical instrument main body 101 is provided for keeping the mechanism of the open mode of header board 65 65 of header boards.

Though in the present embodiment, the sheet element 73 of lid member 70 is made by trnaslucent materials, and this is not restrictive.Lid member 70 just is required and only is configured to when arbitrary LED 75 is luminous, and by the part of lid member 70, light is visible for the player.Figure 11 B illustrates to cover the sectional view that member changes.

Shown in the example of Figure 11 B, by double-colored resin molding, fixed part 81 and lens component (optics display part) 82 can be formed in the holistic lid member 80.Fixed part 81 by be used for sheet element 73 similar trnaslucent materials and make.Lens component 82 is by making with being used for lens component 72 similar transparent resins, and has upper surface 82a, inclined surface 82b and rear end surface 82c, and upper surface 72a, inclined surface 72b and the rear end surface 72c of they and lens component 72 are similar.The upper surface 82a of lens component 82 faces the lens of fixed part 81 to face portion (semi-transparent part) 81a, and lens are the same thin with sheet element 73 to face portion 81a.

Mounting hole 83 forms in the following rear portion of fixed part 81, and by using mounting hole 83, lid member 80 is positioned in panel part 10.Though undeclared, LED 75 is to arrange with same way as shown in Figure 9.Lens have and sheet element 73 identical functions facial 81a, so scioptics are to face portion 81a, only when arbitrary LED 75 is luminous, from the upper surface of lens component 82 send only visible.Just now the simple structure of mentioning and be easy to make.

In the present embodiment, the mechanism that is used for supporting the mechanism of header board 65 rotationally and is used to make travelling arm 42 to slide (slide-and-guide main body 31, blocking lever fixator 37 etc.) is provided at left side plate 23 and transposition arm 22.This is not restrictive.The support portion that is used to support them can be by being fixed to keyboard base 21 and part or member that provide in two or more positions separated from one another on left and right directions are formed.
