Abstract

PURPOSE:To greatly enhance effective printing speed, by a method wherein a carriage is moved at a high velocity, is decelerated immediately before reaching a printing starting position, and is moved at a normal velocity for printing from the printing starting position. CONSTITUTION:When the carriage is stopped at a position A and receives data or a printing command, a printing starting position B1 for the printing command is calculated, and the carriage is moved at a velocity VQ higher than the velocity VP for printing. The carriage is decelerated immediately before reaching the printing starting position B1, and it is moved at the velocity VP from the starting position B1. Printing is conducted concurrently with the movement of the carriage from the printing starting position B1, and when the carriage reaches a printing finishing position C1, data and each command are received. When a paper-feeding command is received, a paper is immediately fed, and a printing starting position B2 for the subsequent printing region P2 is calculated. When the carriage is not in a stopping mode at the moment the calculation is completed, the velocity is directly changed from VP to VQ. Accordingly, the carriage is immediately started to move at the high velocity without being stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a method for driving a ridge in a printer.

A printer drives a paper cartridge based on a printing command and prints on recording paper using a stone head mounted on the Rokkura Ridge. Then, the received data is arithmetic processed to set the printing start position 11, i'';l output L1. After moving the six-pointed edge to this printing start position, move the one-sided edge at a constant speed of PJf, and print in the printing area. When the printing is completed, the six-way printer is temporarily stopped, the next printing start position is calculated, and the one-way printer is moved again to start printing. Of course, during this time, the recording paper is fed, that is, the paper is fed, and the direction of movement for saving waste is also reversed depending on the data.

By the way, it is necessary for the printing operation of a printer to quickly perform a 1j line, and the effective printing speed (unit: 11.I, number of intermittent printing lines) must be high.

The effective printing speed depends primarily on the speed of movement of the paper stock, and for this purpose it is necessary to move one paper stock high. However, on the other hand, the speed at which the bearing ridge moves across the printing area, that is, the movement speed during printing, is
Since it is controlled by the response speed of the head, during printing, the moving speed of the bearing ridge is limited by the response speed of the head.

FIG. 1 is an explanatory diagram showing a conventional example of a method for driving a bea ridge. The moving speed is always equal to the moving speed during printing, and if the bearing ridge is currently at position tt=AK, then printing in the printing area P1 is started based on the received data and printing command. Position B1 and print end position C
□ and start the bearing ridge at the printing speed vp.

Therefore, when the bearing ridge moves 5 and reaches the printing start position B□, it starts printing at the same moving speed and continues the printing operation until the printing end position C1.
When reaching I, the bearing ridge stops and moves to the next printing area P2.
The printing start position 1t:tB2 and the printing end position C2 are calculated. When the calculation of these positions is completed, the bear ridge moves again at the printing speed vp, and moves to the printing area P.
Perform printing in step 2, and then repeat the same operation.

According to such a method of driving the four-wheeled shaft, the moving speed of the shaft is determined by the response speed of the head, as described above, and it is impossible to move the shaft larger than kneading. In addition, after printing is completed, the printer is temporarily stopped in order to calculate the next printing start position and the printing end position, so the time required for one printing is relatively long. The printing speed cannot be compromised too much.

FIG. 2 is an explanatory diagram showing another conventional example of the Bay Ridge driving force method, and parts corresponding to those in FIG. 1 are given the same reference numerals.

This driving method is such that the moving speed of the carriage until it reaches the printing area is greater than the moving speed during printing, and this driving method will be explained using the flow chart of FIG.

Now, when the bearing ridge is at position A and receives data or a printing command, it calculates the printing start position B□ in the printing area P. When the printing start position tBi is calculated, the four-point printer is activated and moves at a moving speed VQ that is thicker than the activation speed vp during printing. Then, when the bearing ridge reaches just before the printing start position B□, it is temporarily stopped, and is started again and moves at the moving speed Vp during printing. During this movement of the bearing ridge, from the printing start position Ju′i, B1 to the printing end position C
When printing is performed up to 0 and reaches the printing end position C□,
Bear Ridge stops. During this period when the bearing ridge is stopped, when there is a command to feed the paper, the paper is fed, and the printing start position B2 of the next printing area P2 is calculated. . below,
Repeat the same action.

The moving speed of the bearing ridge up to the printing start position is not limited by the response speed of the head, since printing is not performed during this time. The driving method of the above Bay Ridge is as follows.
Make the movement speed during this time thicker than the 8-car speed during printing,
Compared to the drive method of the bearing ridge shown in FIG. 1, it goes without saying that the time required for one printing is shorter and the effective printing speed is higher.

However, the moving speed of the rudder and the bearing ridge up to the printing start position is also greater than the moving speed during printing.1. However, since the bearing ridge is stopped just before the print start position and at the end of the print position, there is a loss in zero rotor during that time, and the effective print speed cannot be increased.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the drawbacks of the prior art described above, to provide a method for driving force of a bay ridge, which reduces the difference in stop periods of the bay ridge, and increases the effective printing speed.

In order to achieve this objective, the present invention moves the four-wheel at high speed and decelerates it just before the printing start position f62.
and move it from the printing start position at the printing speed,
And, immediately after printing is completed, the next printing start position is calculated, and the weight position of the printing υ1j is calculated. The feature is that the state is switched from a state of moving speed to a state of high speed movement.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Figure εα4 shows the method for driving the type yoke according to the present invention.
This is an explanatory diagram based on the iiQ example, and parts corresponding to those in Figure 811 are given the same reference numerals.

FIG. 5 is a block diagram showing a specific example of a printer for carrying out this embodiment, in which l is the central processing unit (CPU) of the pot, 2 is the interface circuit (I/F
), 3 is the central processing bag g<7 (cP U), 4 is the random access memory (RAM), 5 is the read-only memory (ROM), 6, 7.8 is the motor drive circuit, 9
1 is a cartridge motor, 1o is a head, and 11 is a paper feed motor.

6th J is a flowchart showing the operation of the 51st printer.

In Fig. 4, assuming that one side of the ridge is currently stopped at position A, when data and printing commands are received, the printing start position B1 of the printing command P is moved out, and the Kanakura ridge (
is the moving speed of the printing 112F■P is also a large moving speed V
Press Q to move at high speed. When the printing ridge comes just before the printing start position B1, the printing ridge is decelerated and returns to the printing starting position B1.
Printing is carried out as the carriage moves from the printing start position B1, which moves at a moving speed of p), and now the carriage moves to the printing end position 1f'i, C, Vc: i-Q. When the paper feed command 111 is received, the paper is immediately fed, and the printing start position B2 of the next printing area P2 is calculated.

On the other hand, Rokuyaritsuji has A゛・子ノU for a certain period of time after printing is finished.
When you press A, it enters stop mode and begins to decelerate. The first is that the data for the next print is received after the previous print has finished, but when there is no longer a need to print and the next data cannot be received, the data is automatically reset at 6. This is to stop the Also, when reversing the moving direction of one V ridge, the A ridge is temporarily stopped, but in this case as well, the sixth ridge is stopped after a certain period of time has elapsed after printing is completed.

Therefore, when the printing in the printing area P1 is finished and the next printing start position B2 is calculated, and when the calculation is finished, if the printer is not in the stop mode,
Now change Yaridge's movement speed I and Vp directly to VQ. For this reason, the Yaridge immediately starts moving at high speed without stopping.

When the calculation of the next printing start position B2 is completed, the printer enters the stop mode and starts to decelerate. 0 The movement speed decreases and it stops once. 1.11) Then it starts up and starts high speed 9 movement at the movement speed VQ. 0Furthermore, if the direction of movement of the six-pointed arrow is reversed, the next printing starts. tI'i's details: When the A-yield is out, when there is no one in stop mode, it immediately goes into stop mode, stops once, 7, then Q, 7 in the direction of pass, and both speeds reverse VQ'''C Move.

In this way, Qi Yarinoji moves from position C□ to the next mark "f"
-1(j1) Moves at high speed to start position MB2, decelerates just before the next printing start position ii:c Let's print in area P2.

4. If there is a command to feed the paper after printing in the printing area P1, the one-sided kiritsuji will move from position C1 to position B2.
The paper is fed at step I7 and step 11. Therefore, positions C1, B
If the distance FA'j between 2 and 2 is short, paper feeding may not be completed while the A-yield moves between this distance, and for this reason, the paper feeding status is monitored and the next Printing start position 1k
B2 and D also indicate 0 if paper feeding is not completed at position 1'j a certain distance forward, 1 indicated by single-dot chain MA, V3'.
Thus, the instruction is to temporarily stop the printer, wait for the completion of paper feeding, and then move the printer at the printing speed Vp to print from the printing □ starting position 1iiB2.

From here on, the same operation is repeated as long as the data is not received. In addition, in this embodiment, the word "Escape" is omitted, but the printing end positions gC□ and c2 are also set to 9. It's out.

Next, the construction of the printer Qj9 for carrying out this embodiment will be described using FIGS. 5 and 6.

h) The CPUI is used for printing data and printing J).

These instructions are sent to 'tCPU 3 via I/F2.
The first thing to be sent to. RAM4. ROM5 has a lot ■! ha
15) Desired data, such as data that determines the point at which the movement speed VpVC is switched, is stored from the collection VQ.The first CPU 3 inputs the received data from the CPU, such as the egg starting position and printing. Set the ending position to ↓−.
Data from the RAM 4 or the ROM 5 is used to set the deceleration start position of the six-wheel drive just before the printing start position and the stop mode after printing is completed. In addition, the CPU 3 also operates a paper feed motor 9, a head 10, a paper feed motor 11, and an I/O motor.
/F2's control is handled by interrupt or )*ware.

Therefore, the data and print 4g instruction from the CPU
) When sent to U 3, it outputs 9° of the print start position (process 12), and sends 1b1 to the ffi operation circuit 6.
Words are set at the print end position and the movement speed change position at the same time, but I will omit the details and explain.
again sends the control number 9 to the drive circuit 6, operates the gear 1 knob motor 9 at a low speed of 8A, and adjusts the gear 1 knob to the speed ■ (4th
1) (processing 14).

When the print head reaches the printing start position, the CPU 3 sends a control signal to the drive circuit 7, drives the head IO based on the receiving data, and prints in the print area.
Process 15) 0 When the printing is completed, the CPU 3 receives the next data and print command from the CPU, and determines whether or not there is a paper feed command (1'). ).When there is a paper feed command, @ sends a control signal to the 1 drive circuit 8 to start the paper feed motor 11 and start paper feeding (
Process 17), calculate the next print amount 4・t(position) (
Processing 18). If there is no paper feed command, the next printing start position is immediately output.

When this calculation is completed, it is determined whether or not the spear enters the stop mode and starts decelerating (determination 19). If deceleration has started, the gear motor 9 is now stopped to stop the fourth gear (process 22). As mentioned above, the stop mode of the -1-1 printer is established after a certain period of time has elapsed after printing is completed. If the printing start position calculation process continues even after the elapse of time, the process is performed by interrupting. When the calculation of the next printing start position 10 is completed, if the deceleration of the spear has not started, it is determined from the received data whether or not the moving direction of the 4 spear should be reversed (
Judgment 20), in the case of reverse rotation, a control signal is sent to the drive circuit 6 to stop the spear motor 9 now (process 22).
). If there is no command to reverse the moving direction of the spear,
The CPU 3 sends control number 16 to the drive circuit 6 to change the current rotation speed of the spear motor 9 to high speed, and set the carriage at a speed of VQ.
(FIG. 4), it is moved at high speed (process 21), and the moving speed vpK during printing is changed immediately before the next printing start position.

Furthermore, when the printer stops due to the stop mode setting or a command to reverse the transfer direction (process 22), the printer starts again in the desired direction (process 13) until just before the next printing start position. High speed moving crane.

The above-mentioned operation continues on the edge of the key when data is received (5), and when data is no longer received, process 18 is not performed, and the machine inevitably starts decelerating.
9) and stop processing 22), the data and print command are returned to C
The first key is sent to PU3, and now the spear stops and remains in the same state.As mentioned earlier, the paper feed operation is not at the printing start position, but at the position before the telephoto distance. If there is a fourth carriage ridge and the carriage does not end at @, the carriage is temporarily stopped, but this is done in step 14.

Furthermore, control for stopping the paper feed during the paper feeding period is performed by interrupt processing.

According to this embodiment, as long as the data is being sequentially received 1δ't, that is, during the period when all the data with θf constant is printed, the +-y ridge is constantly moving without stopping. There is. However, the spear moves at high speed between the printing areas. However, if the 1+Yaritsuji is in the stop mode while calculating the next printing start position, the 6Kiritsuji will stop after printing is completed, but the period from the end of printing to the time when the stop 7-do is set is limited. By setting the longest period of output period such as the printing start position to be slightly longer), it is possible to prevent the central cartridge from stopping except by reversing the direction of movement of the central cartridge. Well, when the type Yarge reaches position C (position ``lii''), which is one square distance before the next printing start position, if the paper feed is not completed, the Yerridge will temporarily stop. , this first (is a strong expression when the printing area of ij'lJ and the next printing area are very close to each other), and these words are correct.

Furthermore, control of the spear motor, head, paper feed motor, etc. is currently performed using interrupt processing, hard web, etc.
Therefore, data and processing are parallelized and speeded up2, and for this reason, there is no need to stop the processing to wait for data processing.

In the above embodiment, each time printing is completed in each printing area, a printing command for the next printing is received. If only printing areas P□ and P2 are layered, printing area P2 is the last printing/IT area of this printing line)
4. Receives a printing command after printing is completed, and receives data that indicates blank spaces such as space codes and horizontal tab codes between each printing area.4. Even in the case of J, the start position and end position of each printing area can be determined by γ-, and the same effect can be obtained.

As explained above, according to the present invention, the 4-1 ridge is moved at a speed corresponding to the response speed of the head in the print area, but the 4-1 ridge is moved at high speed outside the print area, and Since the straw moving speed is not stopped by changing the straw moving speed, the time from when printing is completed in one printing area to starting printing in the next printing area is significantly reduced. First, the effective printing speed is greatly improved, and a new driving force method with superior functionality can be provided without the drawbacks of the prior art described above.
