Digital pen capable of erasing physical handwriting and synchronously eliminating digital track

Abstract

The invention relates to a digital pen capable of erasing physical handwriting and synchronously eliminating digital tracks. The digital pen comprises a pen shell (2), a refill (1), an erasing suite (13), a processor (5), a pressure sensor (3) and a magnetic sensor (4), wherein the refill (1) contains microcapsule type temperature change ink and can be inserted into or pulled out of the pen shell (2), and the refill (1) writes on paper, and starts the processor (5) through the pressure sensor (3) to synchronously record the digital tracks; the erasing suite (13) comprises a rubber erasing head (7) and a magnetic cylinder (9); the magnetic cylinder (9) is inserted into or pulled out of the pen shell (2), the magnetic sensor (4) senses magnetic flux, and working mode conversion between handwriting recording and digital track eliminating is achieved through the processor (5); and the rubber erasing head (7) rubs against the paper to generate heat to erase microcapsule type temperature change ink handwriting, and the magnetic cylinder (9) triggers the pressure sensor (3) to start the processor (5) to synchronously eliminate the digital tracks.

Description

technical field [0001] The present invention relates to a dot matrix digital pen, in particular to a digital pen that can erase physical handwriting on paper and synchronously eliminate the corresponding digital tracks in digital handwriting records, including an erasable digital pen installed on the digital pen housing. Refills and an eraser kit to replace erasable refills. Background technique [0002] Generally speaking, existing dot-matrix digital pens, such as Chinese patent specification CN104932717B, include the following parts: housing; pen core, the nib of the pen core stretches out from the housing; pressure sensor, connected with the tail end of the pen core, When the pen core is written, the pressure generated is transmitted to the pressure sensor, which generates a sensing signal, starts the processor, the signal transmitter and the signal receiver; the signal transmitter, connected with the pressure sensor, transmits detection to the object to be measured aroun...

Problems solved by technology

[0003] However, the above-mentioned existing dot-matrix digital pen products can only draw physical handwriting on paper and record its corresponding digital traces in digital products such as computers and mobile phones, but cannot erase the drawn physical handwriting and synchronize them from digital records. Delete the corresponding digital track

Therefore, existing dot-matrix digital pens cannot be used to simulate scenes such as the daily use of pencils for writing and erasing handwriting with an eraser for primary school students and the use of pencils for middle school students to fill in answer sheets and erasing handwriting with an eraser. Digitize and store in digital form

The above defects have seriously hindered the marketing of dot matrix digital pen products
