在华特曼发明自来水笔4年后的1888年,美国的劳比想发明一种完全不同于自来水笔的新式笔。这是在笔尖上装一个圆珠,写时,随着圆珠的滚动,把墨水留在纸上,这就是我们通常所说的“圆珠笔”。 In 1888, four years after Waltman invented the fountain pen, Loughby of the United States wanted to invent a new type of pen that was completely different from the fountain pen. This is to put a ball on the tip of the pen. When writing, with the rolling of the ball, the ink is left on the paper. This is what we usually call a “ballpoint pen.”
