Embodiment 1

[0024] Embodiment 1, a kind of portable reel music stand, as figure 1 and figure 2 As shown, it includes a bracket and a panel 1 connected to the bracket. The middle part of the panel 1 is provided with a book slot 2 for clamping the music score 10. The binding end of the music score 10 is clamped in the book slot 2, and then can be fixedly supported on the panel. 1 on. The bracket bracket includes a support seat 1-1, the bottom surface of the support seat 1-1 is provided with a universal roller 1-2 with a brake, and the top of the support seat 1-1 is provided with a support rod 1-3 connected to the panel 1, through which the universal roller 1-2 is arranged. Rollers 1-2 can be easily moved.

[0025] The panel 1 is provided with a lifting mechanism and a page-turning mechanism. The lifting mechanism includes a friction wheel 3 provided on the side of the panel 1. The friction wheel 3 is in contact with the outer edge of the music score 10. The friction wheel 3 is fixedly co...

Embodiment 2

[0029] Embodiment 2, a portable reel music stand, the friction wheels 3 are provided with two, the two friction wheels 3 are respectively arranged on the upper and lower parts of the outer side of the music score 10, and the shaft seat 5 is provided with two, two shafts The seat 5 is arranged between the two friction wheels 3 . Two friction wheels are set, which fully guarantees the reliability of the flapping of the sheet music and effectively reduces the probability of flapping failure.

[0030] Other structures of this embodiment are the same as those of Embodiment 1.

Embodiment 3

[0031] Embodiment 3, a kind of portable scroll music stand, as figure 1 , figure 2 and Figure 6 As shown, two page-turning stepper motors 7 are provided, and the two page-turning stepper motors 7 are symmetrically arranged about the book slot 2 and pass the forward rotation switch K1 of the same page-turning stepper motor, the same page-turning step The motor reversing switch K2 is connected with the single-chip microcomputer 20 . After closing the page turning stepper motor forward switch K1, two page turning stepper motors 7 can be controlled to rotate forward synchronously. bit. The angle between the two page turning levers 8 on the two page turning stepper motors 7 is 90 degrees, which can ensure that the two page turning levers will not affect each other when turning pages in the forward and reverse directions.

[0032] Other structures of this embodiment are the same as Embodiment 1 or 2.

Abstract

The invention discloses a portable scroll music stand. The technical problems that an existing spectrometer turning mechanism has complex structure, huge structure and poor practicability are solved.The portable scroll music stand comprises a panel connected to a bracket, a book groove clamping a fixed music score is formed in the middle of the panel, and a side lifting mechanism and a page turning mechanism are arranged on the panel. The side lifting mechanism comprises a friction wheel arranged on the side part of the panel, the friction wheel is in contact with the outer side page side, the friction wheel is driven by a friction wheel stepping motor, the page turning mechanism comprises a page turning stepping motor arranged on the upper side part of the panel, and the page turning stepping motor is arranged between the book groove and the friction wheel. An output shaft of the page turning stepping motor is connected with an L-shaped page turning rotary rod, the friction wheel stepping motor is connected with a singlechip microcontroller through a friction wheel stepping motor switch, and the page turning stepping motor is connected with the singlechip microcontroller separately through a page turning stepping motor forward switch and a page turning stepping motor reversal switch. The portable scroll music stand is simple in structure and small in size, and automatic pageturning of a closing and opening type music score and a scroll type music score can be realized.

Description

technical field [0001] The invention relates to the technical field of music stands, in particular to a portable scroll music stand. Background technique [0002] Music notation is a method of recording music in notation, either printed or handwritten. Music performers and music conductors need to guide with the help of music scores when performing music performances, and need to flip the music scores along with the performance. But the music performer and the music conductor need both hands to use when performing, and the operation of flipping the music score will disrupt the performance rhythm and seriously affect the quality of the performance. [0003] In order to solve the book-turning problem, book-turning machines and page-turning instruments have emerged at the historic moment. There are two types of existing book-turning machines and page-turning instruments: [0004] 1. Paper suction method: adopts aerodynamic principle and uses atmospheric pressure difference to...
