n.活动电影放映机

Edison had a device known as the Kinetoscope. 爱迪生的这种装置叫电影视镜。

His major inventions include phonograph, kinetoscope, dictaphone, incandescent light bulb and tattoo gun etc. 他的主要发明有留声机、活动电影放映机、录音机、白炽灯和纹身枪等。

Although Edison and Dickson made a great contribution to the development of the motion pictures, there was one big problem with the Kinetoscope. 虽然爱迪生和狄克森对电影的发展有很大的贡献，但电影视镜还有个很大的问题。

The kinetoscope, which could only be viewed by one person at a time, was soon replaced by screen projectors, which showed the movie to a whole room of people at once. 电影放映机一开始一次只能有一个观众，不过后来很快就被投影机所取代，这部机器可以让一屋子的人一起欣赏电影。
