    • An electronic pen comprises a writing means (7) which extends into the interior of the pen, a guiding element (9) for the writing means (7), a sensor (15a) for recording images and an image processor (30) for calculating positions of the pen based on said images. The sensor (15a) is part of an imaging detector unit (15). The guiding element (9) and the detector unit (15) are arranged in a common mounting part (5) which is fixedly mounted in the interior of the pen. In such a pen, it is possible to minimize the tolerance chain between the components that convert a pen stroke on a base into a sequence of positions. This enables serial production of the pen with a small number of rejects.
    • 电子笔包括延伸到笔内部的写入装置(7),用于写入装置(7)的引导元件(9),用于记录图像的传感器(15a)和用于 基于所述图像计算笔的位置。 传感器(15a)是成像检测器单元(15)的一部分。 引导元件(9)和检测器单元(15)布置在固定地安装在笔的内部的公共安装部分(5)中。 在这样的笔中,可以最小化将基座上的笔划转换成位置序列的组件之间的公差链。 这使得能够连续生产具有少量拒收的笔。
