Embodiment Construction

[0038] The invention discloses a magnetic roller technology used on a handwriting device, which uses a plurality of Hall components, cooperates with an MCU and multi-pole magnets fixed on the roller to realize continuous data reading and writing of the handwriting device. When the roller rotates, it drives the multi-pole magnet to rotate to generate a changing magnetic field, and the changing magnetic field interacts with multiple Hall components at fixed positions to generate the Hall Effect. Because the position of each Hall component is different, the Hall voltage (phase, current, etc.) induced by each Hall component is different at the same time. The MCU judges and obtains the information of each Hall component according to this phenomenon. The output signal difference is used to judge and calculate the rotation information of the multi-pole magnet (that is, the roller).

[0039] The present invention will be further explained and described below in conjunction with the ac...

Abstract

The invention discloses a magnetic roller device and a rotating information calculation method thereof. The magnetic roller device comprises a multi-pole magnet, an MCU, a plurality of Hall componentsand a roller arranged on a handwriting device. The multi-pole magnet is arranged on the roller and comprises at least a pair of magnetic poles opposite in polarity, and output ends of the Hall components are all connected with an input end of the MCU. The magnetic roller device formed by the multi-pole magnets and the roller replaces a mechanical roller and a touch roller to realize data regulation of the handwriting device, and rotating information calculation and acquisition of the magnetic roller device are realized by cooperation with the Hall components and the MCU, so that the defect oflarge size of the mechanical roller is overcome while problems of proneness to interference and accidental touching of the touch roller and poor production uniformity are solved, and small size, lessproneness to interference, low accidental touching rate and high production uniformity are realized. The magnetic roller device is widely applicable to the field of handwriting devices.

Description

technical field [0001] The invention relates to the field of handwriting equipment, in particular to a magnetic roller device and a method for calculating rotation information thereof. Background technique [0002] In the tablet market, scroll wheels are widely used. The scroll wheel is generally used for continuous data adjustment, which is very convenient and intuitive to use. Currently commonly used scroll wheels mainly include mechanical scroll wheels and touch scroll wheels. Although mechanical scroll wheels have stable characteristics, they are bulky and take up a lot of space on the circuit board. Problems such as poor production consistency. Contents of the invention [0003] In order to solve the above technical problems, the object of the present invention is to provide a magnetic roller device with small size, less interference, low false contact rate and good production consistency and its rotation information calculation method. [0004] The first technical...
