Claims

[Scope of utility model registration request]

A type drum having a cylindrical shape and having a plurality of through holes perforated on its circumferential surface has a plurality of digits of type protruding from the outer surface thereof, and a back surface of the type drum which has a plurality of digits of type protruding from the outer circumferential surface thereof and has a plurality of digits of type protruding from the outer surface of the type drum having a cylindrical shape and a plurality of through holes perforated on the circumferential surface thereof. A flat type sheet with protruding pressing parts to be fitted is wound around the type drum, and a hammer mechanism for pressing the desired type against the paper is disposed inside the type drum for each digit, and ink is applied to the type. In a drum-type printer that presses the type onto paper by driving the hammer mechanism and pressing the pressing part in a coated state to press the type onto the paper and perform desired printing, the type drum is attached to the back side of both ends of the type sheet. A drum-type printer characterized by having a protruding fixing protrusion that is inserted into a through hole.
