This lockable mechanism 60 is worked as follows.Usually the time such as Fig. 8 (a) and shown in Figure 10,, projection 613 is sticked on the jog 421, so contact 42 is prevented to the mobile of width of key direction because spring 612 will push away on the slide block 61.When the arrangement pitch of adjusting key, the power of antagonistic spring 612 and from the top with slide block 61 to pressing down.Its result is that shown in Fig. 8 (b), slide block 61 descends projection 613 is broken away from from jog 421.Thus, contact 42 can move on the width of key direction, therefore only it need be moved to after the suitable position, removes that pressing down of slide block 61 got final product.Thus, slide block 61 is pushed away on the spring 612 once more, stops moving of contact 42 thereby projection 613 is engaged with jog 421, and the suitable arrangement pitch of key is kept.
And the jog 421 that is wavy arrangement preferably is made as the shape that wavy, trapezoidal wavy, the sinusoidal curve shape of triangle etc. has inclination, and jut 613 is preferably formed to being sharp mouth shape.So, when removing the pressing down of slide block 61, based on above-mentioned inclination, projection 613 will automatically enter the recess on the jog 421.Thus, can more easily realize multistage position adjustments on the moving direction.For example, as shown in figure 10,, can be that unit carries out multistage position adjustments then with its length p if form jog 421 with tooth pitch p.So, by can carrying out the structure of multistage position adjustments, can be for different key board units, thus represent and adjustment state is carried out specific realization normalization with common grade.
Figure 11 illustrates and is provided with the example that is used to represent by the key guide part 40 of the mark of contact 42 determined adjusting positions.At the mark 423 shown in the upper left side of figure, be set on the contact 42 as the scale of arranging along the width of key direction, make it possible to the overhang of visualization from supporting mass 41.In addition, at the mark 424 shown in the centre of figure, be set on the central portion of contact 42 as the scale of arranging along the width of key direction, and on supporting mass 41, formed form 412, so that mark 424 can be observed, and on the position of this form, be provided with leg-of-mutton index 413.Thus, can observe the amount that contact 42 deviates from from middle position.As mentioned above, by mark visualization adjustment state clearly is set, and then can be easily and correctly implement to regulate.
These marks 423,424 preferably are provided with the spacing identical with the tooth pitch p of jog 421.When being provided with like this, can with the multistage position adjustments of being undertaken by jog 421 as one man, read amount of movement by mark, thus can be easily and correctly implement to regulate.
And the mark 423,424 among Figure 11 also can only be provided with a certain side wherein.In addition, configuration object can also be provided with on the contrary, set mark 424 and index 413 are arranged at respectively on supporting mass 41 and the contact 42.
Figure 12 to Figure 14 illustrates another other example of key guide part, wherein, Figure 12 is the vertical profile front view of key and key guide part, and Figure 13 is the amplification view of key guide part, Figure 14 (a) is the front view with supporting mass and contact exploded representation, and Figure 14 (b) is its vertical view.Below, the key guide part 50 of dialogue key 10W describes, and for the key guide part 50 ' of black key 10B, because its counter structure with key in vain is identical, and its explanation of Therefore, omited.Key guide part 50 has: bar-shaped supporting mass 51, and it is fixed on the keyframe 20 and in the hollow bulb of key and extends; Contact 52, it is supported by this supporting mass.The cylindrical portion of supporting mass 51 upper ends is divided into the fulcrum 511 that is used to install contact 52.Contact 52 has: the installation portion cylindraceous 521 that the upper end is closed, and the operating member 522 that is fixedly installed to this installation portion upper end.Operating member 522 is to be formed by the plectane body of horizontal arrangement, and the central axis (its central axis 511x with fulcrum 511 is identical) of the hollow bulb 521v on its central axis 522x and the installation portion 521 is parallel, and has been positioned at eccentric on the position apart from s (Figure 14).The circumferential part of operating member 522 is set as, and has the shape that edge part is the circle of arcuation section.Contact 52 covers with the form lining that the fulcrum 511 with the supporting mass upper end passes in hollow bulb 521v.On the sidewall of hollow bulb 521v, be formed with circular protrusion 521w, on the sidewall of fulcrum 511, be formed with annular recessed portion 511w on the position corresponding with this jut.Under the state that contact 52 is installed on the fulcrum 511, this circular protrusion 521w and annular recessed portion 511w be by elastic deformation and chimeric, plays the effect that comes off of preventing, thereby keep installment state.So, contact 52 is can be supported around the mode that axis rotates with respect to fulcrum 511.
The external diameter of operating member 522 is confirmed as, than the side wall inner surface of key 10 to deviate from distance smaller, thereby so that it realizes guide function near the key side wall inner surface.Therefore, key 10 is being installed under the state of keyframe 20 and key guide part 50, determined the position on the Width of key by operating member 522, when contact 52 is rotated with respect to supporting mass 51, along with moving of the operating member 522 that is positioned at eccentric position, key 10 changes its position on Width.
By key guide part 50, can be with the arrangement pitch of following this mode adjusting key.State after adjusting when Figure 13 illustrates interval too small between white key, in Figure 13 (a), the leading section that the rotation by contact 52 makes eccentric moves to left, thus, sidewall 13 is moved to left.In Figure 13 (b), the leading section that the rotation by contact 52 makes eccentric moves to right-hand, thus, sidewall 13 is moved to right-hand.Its result is, becomes suitable arrangement pitch thereby the gap between adjacent white key is extended.But, according to the difference of the configuration status of key, regulate in order to carry out arrangement pitch, only need contact with the key of the side in the adjacent key to move sometimes and get final product, also need sometimes the contact of adjacent a plurality of keys is moved to equidirectional.
Figure 15 illustrates an example of the horizontal section of key guide part, in this example, on the sidewall of supporting mass 51, be provided with a plurality of engaging recessed parts 512, the madial wall of hollow bulb of bringing into play the contact 52 of function as movable contact is provided with engaging protuberance 524, and one in engaging protuberance 524 and the engaging recessed part 512 engages.Thus, can set the turned position of contact, and for different key board units interimly, thereby can represent and the rectification state is carried out specific realization normalization with common grade.In addition, can also improve the resistibility of the counter-force that when correcting contact 52 bears from key sidewall 13 by concavo-convex engaging.And engaging recessed part also can be to be configured with above-mentioned opposite mode on supporting mass 51 and contact 52 with the engaging protuberance.
The supporting mass and the contact that constitute key guide part mentioned above can be made of various materials, and for example supporting mass can use metal, plastic or other material to make, and contact can use material such as resin, elastic body, rubber.
The present invention is not limited in above-mentioned embodiment, can also carry out various changes.For example, for contact is regulated at the enterprising line position of width of key direction, as mentioned before, can adopt straight line as contact to move or exercises such as rotation.Under the situation that adopts straight line to move, except slip, can also adopt as on the side face of contact, forming screw thread along straight line, thus the move mode by making the contact rotation that it is moved etc. to the thread spindle direction.In addition, adopting under the situation of rotating, contact only needs the part (circular-arc part) of the circle of off-centre is got final product as the surface of contact with supporting mass, the axis along the vertical direction of pivot center in adopting example as mentioned before, can also adopt the axis of along continuous straight runs.
Can adopt as lockable mechanism, can be in order to carry out that arrangement pitch is regulated and movably contact can be fixed on variety of way on the assigned position with respect to supporting mass, for example can adopt: thus by stepping up the chimeric mode that rubs and keep of utilizing of supporting mass and contact; By between supporting mass and contact, being pressed into the mode that chock is fixed; The stop pin that will insert this hole along a plurality of Kong Yuke of the moving direction setting of contact is arranged on the side and the opposing party of supporting mass and contact, thus mode of the insertion fixed position by stop pin etc.In addition, under the situation that lockable mechanism is not set, also can be after position adjustments contact be fixed on supporting mass by methods such as bonding, welding.Described mark except can the position of supporting mass and contact make relatively the time amount of movement of contact can visualization, can also be set to, the comparison of the position by being fixed in other parts on the keyframe and contact comes the amount of movement of visualization contact.In addition, serve as a mark, can adopt printing, mint-mark, projection, groove, hole, window, scale, make pattern that live width or color etc. change etc. on moving direction.When the position to the contact after the position adjustments keeps, except with the closely chimeric method of the through hole of supporting mass, can also utilize various maintenance methods, threaded through hole for example is set, by dogbolt being screwed into method that makes its front end and contact butt etc. on the sidewall of supporting mass.
