Embodiment Construction

[0040] A preferred embodiment of the present invention will now be described with reference to the accompanying drawings.

[0041] figure 1 A tape printer 1 according to an embodiment of the present invention is shown. like figure 1 As shown, the tape printer 1 has a keyboard 3 having a plurality of keys such as character keys and control keys on the top surface of the main body 2 . like figure 2 As shown, the tape printer 1 also includes a frame 11 containing the cartridge. The case-containing frame 11 is configured to removably receive a tape-containing case 30 . The frame 11 containing the cassette is provided with a tape driving / printing mechanism 10 and a cutting knife 17 for cutting the tape. An eject port 5 is formed on the side of the main body 2 . A printed tape is pulled out from the tape-containing cassette 30, cut by means of the cutting knife 17, and then ejected to the outside of the main body 2 through the tape eject port 5. In addition, a control circui...

Abstract

A printer prevents displacement of the printing dot matrix caused by reverse rotation of the DC motor when power supply to the DC motor is restored. When the power supply to the DC motor is suspended, the DC motor often rotates in the reverse direction before the motor rotation stops. The amount of reverse rotation is detected by an encoder. This amount of rotation is compensated immediately after the DC motor power supply is restored. After detecting the same amount of forward rotation as the amount of reverse rotation, printing is resumed by the print head.

Description

technical field [0001] The present invention relates to a belt printer which performs line printing on a printing medium using dot patterns. Background technique [0002] A tape printer is a well-known device in unwinding and running a wound long tape using a DC motor (hereinafter referred to as a DC motor), and performing line printing on the unwound tape using a dot pattern. Some of these tape printers are provided with a cutting knife for cutting the tape downstream of the printing station. Since the original tape can be cut manually or automatically after printing, a printed tape having a desired length can be produced. [0003] The above-mentioned tape printer can be provided with an encoder to detect the amount of rotation of the DC motor. The encoder has a rotating disk having a plurality of radial grooves formed at regular intervals in the circumferential direction. The disc is attached to the output shaft of the DC motor. The encoder has a light sensor having a ...
