Abstract: A tape creating apparatus, including a printing device that prints characters on label tape that includes a winding margin portion that is wound around a periphery of a cylindrical member and a flag portion that is uniformly formed with the winding margin portion, wherein the characters are printed on the flag portion, a first input device for inputting a diameter of the cylindrical member, and a first setting device for setting a length of the flag portion and a length of the winding margin portion on the basis of the diameter of the cylindrical member as input by the first input device.

Abstract: A tape printer that prevents shifting of a printed dot due to a reverse rotation caused by the DC motor stop when power supply to a DC motor is resumed. When the power supply to the DC motor is suspended, the DC motor often rotates in a reverse direction immediately before rotation of the motor stops. The amount of reverse rotation is detected by an encoder. This amount is compensated immediately after the power supply to the DC motor is resumed. After the amount of forward rotation identical to the amount of reverse rotation amount is detected, printing is resumed by the printing head.

Abstract: A tape printer for securing a time period sufficient for processing printing data even if the rpm of a DC motor increases, when an encoder is used for detecting rotation of the DC motor. When the DC motor does not rotate at a constant speed, in principle, the encoder detects an amount of rotation of the DC motor. Accordingly, a thermal head is driven for printing, every time a predetermined angle of rotation is sensed. On the other hand, when the DC motor rotates at a constant speed, the thermal head is driven for printing at constant intervals.
