Problems solved by technology

In order to change the circuit or rewrite the ROM, it is difficult to do it easily because it involves the operation of disassembling the printer.
[0029] As described above, in the serial printer, in addition to the fluctuation of the play between the shaft of the drive motor and the carriage, there is a delay from the application of voltage to the pulse motor to the start of movement of the carriage due to changes in the environment or over a long period of time. There is a problem of positional deviation in the printing position during reciprocating printing due to fluctuations in time, etc.

Abstract

In generating a timing of print drive for controlling the printing of a printhead on the basis of a detection signal of an encoder, the timing of print drive is adjusted by adjusting the detection signal of the encoder to correct a displacement of the printing position in reciprocating printing. A serial printer comprises a motor for reciprocating a carriage with a printhead and an encoder for detecting the rotation of a motor shaft. The serial printer controls the timing of print drive of the printhead on the basis of a detection signal detected by the encoder and adjusts the duty ratio of the detection signal of the encoder.

Description

technical field [0001] The present invention relates to a serial printer that drives a print head while reciprocating a carriage on which the print head is mounted, a control method thereof, and an encoder suitable for controlling the serial printer. Background technique [0002] Conventionally, a serial printer is known that drives a print head to perform printing while reciprocating a carriage by rotating a pulse motor in forward and reverse directions. [0003] In such a serial printer, as a method of controlling the driving of the carriage or the print head, a method of using the timing of a pulse motor drive signal for driving the pulse motor for driving, or detecting the timing of the pulse motor for driving with an encoder is known. Rotate and utilize the method to detect the signal. [0004] In such a serial printer, in order to prevent printing misalignment, it is necessary to control the driving of printing elements of the print head in addition to controlling the...
