摘要：
A pin-tractor type paper feed mechanism is disclosed which includes feed belt with pins for feeding paper having perforations along the edges of the paper, the pins of the feed belt being engageable with the perforations of the paper. An endless film is provided between the top surface of the paper and a fixed first pressure plate so as to press against the top surface of the paper. A second fixed pressure plate is provided. The endless film and the feed belt are rotated in synchronism such that adjacent runs of the film and the belt advance in the same direction. As a result, no frictional force is applied to the top surface of the paper, and damage to the paper and improper feeding of the paper are prevented.
