摘要： PURPOSE:To enable to automatically eliminate the sag of a ribbon in an initial period of setting, by a method wherein an initial ribbon take-up quantity is set to be larger than the distance through which a carriage is moved when being returned after printing is started. CONSTITUTION:When a printing-starting switch is turned ON, an initial position detecting part detects the position of the carriage E, and when the carriage E is located at the initial position, a driving circuit is operated to once move the carriage E rightward. In this case, the next decision by the detecting part is negation, and a signal is fed to the driving circuit and a driving circuit for taking up the ribbon. While again returning the carriage E to the initial position, a motor 37 for a ribbon-feeding mechanism I is driven by a preset number of steps to take up the set ribbon by an amount corresponding to the initial sag. Then, the carriage E is moved from the initial position to a printing-starting position. The next decision by the detecting part is negation also when the carriage E is not located at the initial position. In this case, the motor 37 is driven while returning the carriage E to the initial position, thereby taking up the ribbon by an amount corresponding to the initial sag, and the carriage E is moved to the printing-starting position.

摘要： PURPOSE:To maintain a uniform prining pressure and enable a thermal head to be appropriately brought into contact with and separated from a platen, by pressing a thermal head directly by an elastic member. CONSTITUTION:When printing, a solenoid 38 is turned ON to excite an operating rod 40. The operating rod 40 is drawn in the direction of an arrow (a), and a pressing member 42 is released from a head holder 14. The thermal head 10 is pressed by the elasticity of the elastic member 32 through an upper pressing member 38, is rotated counterclockwise, and is elastically pressed against the platen 12 at a fixed pressure. To separate the head 10 from the platen 12, the solenoid 38 is turned OFF to clear the excitation of the operating rod 40. The operating rod 40 tends to return to an initial position in the direction of an arrow (b), and protrudes, thereby pressing the head holder 14 through the pressing member 42. Since a lower elastic member 48 has an elasticity higher than that of the upper elastic member 32, the pressing member 42 presses the head holder 14 as against the elastic member 32. By this, the thermal head 10 is rotated clockwise against the elastic member 32, is separated from the platen 12, and is positioned with a gap 50 left between the head 10 and the platen 12.

摘要： PURPOSE:To enable to impart a stable back tension to a ribbon for a long period of time with a simple construction, by integrally providing a braking member capable of making sliding contact with a spool. CONSTITUTION:At a bottom part position of amain body 34 of a cassette where a thermal printing ribbon body 35a is fitted, the spool 93 of the ribbon body 35a is provided, and the braking members 94 capable of making sliding contact with the ribbon body wound on the spool 93 are elastically provided in an appropriate number by cutting and riasing a bottom part 34c above a bottom surface 34d. Therefore, when the ribbon body 35a is set onto a boss shaft 40, the braking members 94 gives the ribbon body 35a a braking force as a rotation load. In this case, when an upper cover 34a is fitted to the main body 34, the ribbon body 35a is prevented from being levitated from the boss shaft 40, and the braking action is maintained to be constant. The braking members 94, 95 gives a constant braking effect to the rotation of the ribbon body 35a. Accordingly, excessive rotation of the ribbon body 35a in a ribbon letting-out direction due to the tension of the ribbon part down out to a printing mechanism is forcibly braked.

摘要： PURPOSE:To appropriately eliminate the sag of a ribbon generated during printing, by constantly applying an appropriate tension to a ribbon being led out during printing. CONSTITUTION:When a printing-starting switch is turned ON, a solenoid 89 is excited to retract an operating rod 88 leftward, a traction member 87 collides against an elastic member 81 provided at the part of a hole 86, and the member 81 is pulled leftward against the elasticity of the first elastic part 81a. While bending the member 81 by traction, a head holder 75 is rotated clockwise. At the time of printing, a thermal head is brought into contact with a platen by a traction pressure generated by the solenoid 89. When printing 94 is started and a preset number of printed characters is detected by a printed character number deciding part, an affirmation signal is fed to a driving circuit for the next ribbon-feeding motor 37. Upon receiving the signal, the driving circuit drives the motor 37 by a preset number of steps. By this, a driving shaft 39 is rotated in the direction for taking up the ribbon, so that the ribbon led out to a printing part is instantaneously pulled and taken up by an amount corresponding to the sag. The ribbon taking-up operation is conducted between printing timings.
