Description
Technical field
The present invention relates to a kind of book page-turning device, particularly a kind of piano spectrum automatic-turning-page device.
Background technology
At piano, during to the page turning of qin spectrum, often need to stop and play or utilize the gap of playing to free hand to carry out page turning, likely cause play interrupt, discontinuous or affect playing effect, therefore in the urgent need to a kind of piano, compose automatic leaf turner.Automatic leaf turner of the prior art, all be not applicable to the qin spectrum automatic leaf turner that piano is used, as " automatic page-turning music stand (patent No.: ZL95236571.5) " complex structure, the single page music score of Chinese operas of special manufacture is used in requirement, and traditional song, qin spectrum are originally out of use; Also there is complex structure in prior art " foot automatic staff turning frame (patent No. 92212343.8) ", manufacturing cost is high, and inconvenient problem with use is equally all not suitable for the automatic page turning of piano spectrum and uses and can not get applying.
Summary of the invention
Piano spectrum automatic-turning-page device of the present invention, comprises base plate, this backup plate of music for piano, motor, train of reduction gears, sector gear, return spring, limit switch, driving lever, elastic bending steel bar, brake pad, pedal switch.Described motor, train of reduction gears, sector gear, return spring, limit switch are all arranged on base plate; Driving lever, elastic bending steel bar one end are arranged on sector gear planar central position; Brake pad is arranged on the end of elastic bending steel bar, and be pressed in this upper right corner of music for piano, foot pedal switch connection motor power when pianist needs page turning, electric machine rotation slows down and drives sector gear to rotate through train of reduction gears, under the effect of elastic bending steel bar and brake pad, promote page upper right corner protuberance, driving lever turns over the page to the left side subsequently, completes automatic page turning process.After page turning completes, limit switch quits work motor, and sector gear goes back to original position under the effect of spring, waits for the page-turning instruction of pedal switch.
Piano spectrum of the present invention automatic-turning-page device elastic bending steel bar one end is connected in sector gear planar central, the other end arranges brake pad, brake pad is pressed in qin spectrum upper right side under the effect of elastic bending steel bar elastic force, when sector gear rotates, frictional force is composed under the page angle of uppermost one page upper right qin and is pushed protuberance, driving lever subsequently promotes this one page and overturns left and compacting, completes page turning work.Driving lever can also can be with plastics or metal material with composite.
Described piano spectrum automatic-turning-page device sector gear and train of reduction gears engagement, sector gear planar central position arranges plastics driving lever and elastic bending steel bar, and the lower end, the left side of sector gear arranges back-moving spring, and lower right arranges limit switch.After page turning completes, back-moving spring makes sector gear go back to original position, and driving lever, elastic bending steel bar also return to original state, wait for the instruction of next page turning.
Described pedal switch is arranged on the left side of piano foot key, and pedal switch is controlled motor power, gently steps on left foot and just can make very easily page turner work while needing page turning.
Described limit switch is arranged on the lower right of sector gear on base plate, spacing Height Adjustable.Page turner work is rotated sector gear, cuts off motor power when touching limit switch, and sector gear is got back to reset condition under the effect of back-moving spring.
Between described piano spectrum automatic-turning-page device base plate and this backup plate of music for piano, rotation loose-leaf is set, base plate and this backup plate of music for piano can form any angle, conveniently install and use.
Between described driving lever and elastic bending steel bar, shape has a certain degree, and after the assurance page swells under brake pad effect, driving lever climbs over the page.Driving lever tilts from outside to inside from this backup plate of music for piano plane, and elastic bending steel bar tilts from the inside to the outside from this backup plate of music for piano plane.
Piano spectrum automatic-turning-page device beneficial effect of the present invention is: overcome the deficiencies in the prior art completely, can be suitable for various traditional songs, song, spectrum originally, automatic page turning needs while being not only applicable to piano performance, can use equally and need to compose on the various musical instruments of originally playing various, simple in structure, low cost of manufacture, economical and practical, easy to use, be extremely easily widely applied.
