Abstract

PURPOSE:To obtain uniform-quality printings by varying the driving time of a printing hammer according to the moving distance of a carriage. CONSTITUTION:Key information put in a key board 101 is once stored in a key buffer 102 and then orderly read in CPU 103 where a carriage motor, a printing hammer, etc., are driven according to the key information. In short, when driving the carriage, the moving amount of the carriage makes reference to a predetermined moving amount conversion table 105 by a control program 104 according to the key information. At the same time, the data of UP/DOWN counter 107 displaying the present position of the carriage is added to the moving amount by CPU 103, the result is written down in a carriage position register 108, and at the same time the moving amount is stored in the register 118.

[Detailed Description of the Invention] In recent years, in printing devices such as electronic tie writers, stationary impact printers are often used in which printing is performed after the type elements and bearings are completely stationary in order to improve printing quality. DC servo control, pulse motors, etc. are used to control these printing units, and the speed is controlled according to the distance traveled by the bearing. Then, a stop signal is issued in the vicinity of the first target position of the carrying ring, and in synchronization with this, a driving signal for the printing hammer is issued, and printing is performed immediately after the carrying comes to rest.

その時の静止位置は非常に精度が要求され、かつ高速度

The stationary position at that time required extremely high precision, and the greatest goal was to move it to the target position at high speed.

However, those controlled by DC servo control and pulse motor control cause transient responses to stop signals,
Furthermore, it is difficult to obtain the same transient response for all distances traveled by the bearing.

However, waiting for this transient response to completely converge before printing leads to a decrease in printing speed, and improvements have been desired.

The present invention has aimed at the above-mentioned improvements, and has achieved stable printing quality even when the printing hammer is driven during normal intermittent printing and the movement of the tab printing tab and the like.

FIG. 2 is a time chart showing the transient response when the carrying is stationary and the timing of the carrying signal and printing hammer. In the figure, the target position where the bearing stops is LO
It is shown by . In normal intermittent printing, it is moved from Ll. That is, the moving distance is 11, but when printing a tab, etc., it moves from L2 and the moving distance becomes 12. Also, each transient response is 1. It is represented by a2. Stop signal is at target position L
It is set to occur when reaching a certain distance from O. 1. As can be seen in a2, the transient response is different, so if the printing hammer is driven at the same time T1 from the carrying stop signal, printing will be performed in a2 before the vibration of the carrying ring has disappeared, and as a result, the printing position will change. Accuracy will deteriorate. Therefore, in the present invention, the printer is arranged in such a way that printing can be performed at the maximum printing speed during normal printing, while the printing speed is slowed down by setting the printing door rotation time to T2 only during tab printing to ensure printing position accuracy. .
