Abstract

PURPOSE:To provide the titled system carrying out space control at the start time of a new line efficiently in a wasteful time reduced state, constituted from such a mechanism that space operation is initiated at the start time of a new line without waiting the completion of a new line to perform space control so as to be capable of starting printing. CONSTITUTION:Space control is performed in such a manner that, when printing is finished at a time t2, the operation of a new line is started and space motor is decelerated and stopped to start space operation at a time t3' without waiting the completion of a new line. This space operation is started in expectation of the completion in new line operation at a time t4' when printing is started. When operation of the new line is finished, printing operation can be rapidly started.

Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention enables a line dot printer to enter the next space operation without waiting for the end of the line feed when the printing operation moves to the next line. Concerning space control methods for line dot printers.

[Prior art and problems]

FIG. 1 is a diagram showing the operation timing of a space control method of a conventional line dot printer.

The conventional space control method, as shown in Figure 81T1,
When the space operation is entered at the time of to, the printing operation is started at 11 o'clock and printing is performed. Immediately after printing is completed at 5:00 p.m., a new movement operation is started and the space motor starts decelerating and stopping operation. Space operations will stop at 1:00 p.m.
The start of the next space operation is made to wait until the end of the new space operation. When the line feed operation ends at 14:00, the next space operation is started upon receiving a report of the end of the line feed. Generally, it takes about 3 Qms to stop the space motion, and about 50 to 60+ns to change the space motion. Therefore, as shown in Figure 1, 20 to 30 m
5 pause time T%v75! However, even after entering the next space movement, it stops at the start, and it is about 5 times longer than 1 stitch.
Since it takes a part of the time of about 0 ms, time is wasted during this time.

[Purpose of the invention]

The present invention is based on the above consideration, and is based on the above considerations.

In the present invention, as shown in FIG. 2, when printing ends at 12 o'clock, the space motor starts the feed operation, decelerates and stops the space motor, waits for the end of the line feed, and starts the space operation at 1 o'clock with the space control 1rs. It will be done. This space operation is started with the assumption that the paper feed operation will be completed at the time t4' when printing starts. Therefore, if the paper feed operation is full, the printing operation can be started promptly at β.

FIG. 3 shows the nl configuration of the printer control system. In FIG. 3, various commands, addresses, print data, etc. are sent from the sending side to a CPU (processing unit) 1, and a control signal for receiving data is sent to a data reception control circuit 7.

Print data is sometimes sent as an image or as a character code, but in the CPUJ, when print data is sent as an image, it is sent directly to the line buffer section 11 through the selector 10 as an image. The data is stored, and when print data is sent in character code, the character code is converted to image data by the CG-R OM read control circuit 9, and then input selector]0
Control is performed so that image data is stored in the line buffer section 11 through the line buffer section 11. The write address of the line buffer unit 11 is given by the line buffer write control circuit 8.
The write control circuit 8 is controlled by the data reception control circuit 7 and the CPU 1. The print data stored in the line buffer section 11 is sequentially read out and sent to the print pin drive control circuit 12. The CPU 1 controls the print bin drive circuit 12 to control the printing operation, and when the printing operation is finished, controls the T and F control circuit 2 to start a line feed (T, F).
It controls the movement, and controls the space motor control circuit 4 during the change movement to control the stop and restart of the space movement.

Next, while referring to FIG.
] The processing flow will be explained. When the CPUI receives print information, it processes it in the following order.

■ Transfer the print data to the line buffer.

Next, perform the process (■).

■ Check whether or not the insertion into line buffer 8 has been completed.

If No, the process returns to ■, and if Yes, the process of ■ and ■ is performed.

■ Check whether line buffer B is empty.

If the answer is No, wait until the answer is Yes, and if the answer is Yes, perform the process described in (2).

■ Load print data 71 into line buffer B. Next, perform the process (■).

■ Check whether the transfer to line buffer B has been completed.

If No, return to the process of ■; if Yes, proceed to k■
Perform the processing of and ■.

■ Check whether line buffer A is empty.

If the answer is NO, wait until the answer is yes, and if the answer is yes, return to the process of (2).

■ Start Space Motor 5. Next, perform the process (■).

■ Read print data from the line buffer and perform printing. Next, perform the process (■).

■ Check whether printing has finished or not.

In the case of I'Jo, return to the process of ■, and in the case of Yes, perform the [phase] and 00 processes.

[Phase] Start line feed (LF) operation.

■ Stop the space motor 5 and return to the process of ■.

FIG. 5 shows the operation timing according to the above processing. First, print data is drawn into line buffer A. When 71 has been written to line buffer A,
Next, loading into line buffer B is started, and at the same time, a space operation is started. When the space operation reaches a constant speed and enters the print area, a print operation is started.
During this printing operation, vJ filling into line buffer B is completed.

When printing is completed, the line buffer A becomes empty, and the next print data is immediately started to be inserted, and at the same time, the start of the line feed operation and the stop of the space operation are controlled. The space operation will start again without waiting 5 seconds for the line break to end.
When entering the print area, the data read from line buffer B is printed. By the time the thermal printing operation begins, the line feed has finished, and the filling in the line buffer B also ends during the printing operation. When the printing is completed, as described above, the printing data is started to be transferred to the now empty line buffer 13, and at the same time, the start of the line feed operation and the stop of the space operation are controlled. Thereafter, in the same way, the print data is transferred to line buffers A and B, and the complicated print data is read out and printed. This indicates that the entered print data will be printed in the same numbered ■ space, and the print data received in line buffer ■3 will be printed in the same numbered ■ space. The same goes for , lower ■ or [phase].O.The height of the space waveform indicates the speed of the space movement, and although it is not directly related to the present invention, it is similar to ■ or ■ and ■ or [phase]. On the other hand, ■ and ■ are high.This is because the former occurs when, for example, Chinese characters with a high print dot density are printed, and the latter occurs when, for example, alphanumeric characters with a low print dot density are printed.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, space control is performed in such a way that printing can be started without waiting for the end of line feed at the time of line feed, so there is no wasted time at line feed and the system , throughput can be improved.
