Electromagnetic pen with a multi-functions tail part

Abstract

The present invention relates to a multi-function electromagnetic pen, and particularly relates to an electromagnetic pen with a multi-function tail part. This electromagnetic comprises a body, a pen-tip part, and a multi-function electromagnetic ring. The pen-tip part is disposed on the front part of the electromagnetic pen and the multi-function electromagnetic ring is disposed on the tail part (or rear end part) of the electromagnetic pen. The multi-function electromagnetic ring can emit different electromagnetic signals with different frequencies. These electromagnetic signals with different frequencies are defined by a tablet to represent different functions (or modes), for example erasing function (or mode), magnifying function (or mode), and palette knife function (or mode). A user can control and change the frequency of the electromagnetic signal emitted form the multi-function electromagnetic ring by pressing the switch on the body of the electromagnetic pen. By this way, the function of the multi-function electromagnetic ring can be controlled and changed. Therefore, it has no need to perform or start the function (or mode) of the tail part of the electromagnetic pen (or the multi-function electromagnetic ring) by the contact between the back part the electromagnetic pen (or the multi-function electromagnetic ring) and the tablet. Accordingly, the tail part the electromagnetic pen (or the multi-function electromagnetic ring) can work above the tablet without contact with the tablet, and it can prevent the tail part the electromagnetic pen from the damage caused by the contact.
