ABSTRACT:
A printer allowing attachment and detachment of an external device for improving a paper feed system. The printer allows either an automatic sheet feeder for successively feeding a plurality of cut sheets of paper or a tractor device for feeding a continuous sheet of paper as the external device to be selectively mounted, and the printer itself includes a permanent tractor, in which the permanent tractor and the external device can be driven by a common driving source. More specifically, the printer includes a printing mechanism, a paper feed path communicating with the printing mechanism, a driving source for the paper feed system, and an output gear connected to an output shaft of the driving source. The permanent tractor is located so as to communicate with the paper feed path, and includes an input gear connected to the output shaft of the driving source. The selective transmission of a drive force from the driving source to either the input gear of the permanent tractor or the output gear is effected by a drive force selecting mechanism operated by an operating member in the printer.
