Claims

[Claims for Utility Model Registration] (1) A cartridge including a platen, a carriage reciprocating along a guide means including a guide shaft oriented parallel to the platen, and a printing head, the printing head being connected to the platen. a head assembly that is pivotally connected to the guide shaft or the carriage so as to be able to move toward and away from the head assembly and reciprocates with the carriage; a spool for winding up the ink ribbon provided on the carriage; and movement of the carriage. spool rotation drive means for rotationally driving the spool in a predetermined direction as the spool rotates, the spool rotation drive means comprising a roller operatively connected to the spool and a roller oriented parallel to the platen. and a rail member that operates in a freely connectable manner to the roller, and
A printer characterized in that a frictional engagement means is provided between the roller and the rail member for frictionally engaging them. (2) Claim (1) for utility model registration states that the frictional engagement means is made of a material with relatively high frictional resistance, such as cork, and is attached to at least one of the rollers or rail members. Featured printers. (3) In claim (1) or (2) for utility model registration, the rail member is rotated by a driving means such as a solenoid and is engaged with a rotating plate, and the rotating plate is engaged with the rotating plate. A printer characterized in that it comes into contact with and leaves the roller as it moves. (4) In claim (1) or (3) of the utility model registration, the head assembly includes a second rail member that rotates together with the rail member and moves the head assembly toward and away from the platen. A printer characterized in that the printers are slidably engaged.
