Page turner

Abstract

The invention discloses a page turner which starts and turns pages through a guide vane (6), an angle plate (5) and a page turning vane (3). The guide vane is bonded to the back of a page (10.1) which is placed on the angle plate and required to be turned; the guide vane at least partially extends outside the page (10.1); the part which extends outside the page (10.1) is placed on the angle plate; the external side of an overlapped part of the guide vane and the page is bonded to the page; the page turning vane is articulated on a base (7) and connected with a driving device (4); due to the elastic deformation, the free end of the page turning vane in an initial position closely clings to the surface of the part of the guide vane extending outside the page; and the movement track of the free end of the page turning vane passes through the part which is not bonded with the page in the overlapped part of the guide vane and the page. The invention has the advantages of accurate page start, flexibility, simple structure, low manufacturing cost and capability of turning pages of music books or books in a volume form.

Description

technical field [0001] The invention relates to a page turner capable of automatically turning pages. Background technique [0002] When practicing or playing a musical instrument, the musician usually puts the score on the music stand (such as Erhu, Dizi, etc.) or directly on the musical instrument (such as the piano). When needing to turn over the music score, the player has to free his hands to turn the music score while both hands are playing together, which is inconvenient and affects the practice efficiency or performance effect. In addition, for people with hand disabilities, such a simple action as turning a book will require a lot of energy, and it may even be impossible to complete. For this reason, people have designed many devices that can automatically turn pages. Through the analysis of the prior art, the key technology of the page turner is how to start the pages accurately, and the technology for starting pages can be summarized as follows: 1. Page method (...

AI Technical Summary

Problems solved by technology

Among the above methods: the adhesive page method has strict requirements on the bonding strength of the adhesive head. If the viscosity is too strong, the page will be torn easily. The suction page method has a complicated structure, which has requirements for the thickness and smoothness of the paper, and its reliability is not high; the friction rubbing wheel method is similar to the paper feeding principle of a copier. Accurate, and not suitable for booklets or books; the number of pages held by the fixed frame rotation method is limited, not suitable for booklets or books, and the range of motion is too large; the roll method needs to be copied first, Then put it into the page turner in order, and it is not suitable for booklets or books; the LCD screen display method needs to scan and record the scorebook, and the price is too expensive
