日本名古屋大学专家和雅西马公司工程师共同研制成一种带有存储器的圆珠笔样品。在其笔杆中除了装有普通笔芯之外,还装有一个光学传感器——一个超微型电视摄像机。它每秒10次拍摄笔尖下书写的文字。此外,圆珠笔还装有一个压力传感器,可记录书写两个单词之间的间隙。所有数据被输入容量为1兆比特(即500页文字)的存储器中。存储器是一个小盒子,用导线与圆珠笔相连。目前新型圆珠笔还 Japan’s Nagoya University experts and Yashima engineers jointly developed a ball-point pen with memory samples. In addition to the pen cartridge, an optical sensor, an ultra-miniature TV camera, is installed. It takes 10 times per second to photograph the writing under the pen tip. In addition, the ballpoint pen is also equipped with a pressure sensor that records the gap between two words written. All data is entered into memory with a capacity of 1 megabit (500 pages of text). The memory is a small box that is connected to the ballpoint pen by wire. The new ball-point pen also
