DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing apparatus for printing necessary items on a passbook or a slip used in a financial institution or the like. In recent years, the number of jobs printed on passbooks and slips has been steadily increasing due to the passbook processing device installed at the counter of financial institutions, and the processing speed has been further increased from the viewpoint of improving service to customers. Is required.

[0002] Means for realizing high-speed processing include a high-speed conveyance speed, a high-speed magnetic data processing, and a high-speed printing process. Among them, a remarkable effect cannot be expected with respect to the increase in the transport speed because the transport distance is not so long. Further, comparing the time required for magnetic data processing and the time required for printing processing, the latter is longer.

Therefore, the most effective way to increase the speed is to speed up the printing process.

[0004]

2. Description of the Related Art A medium processed by a passbook processing apparatus prints a passbook for printing a customer's transaction history, forms such as a deposit certificate issued at the time of a request from a customer, and management information.
There are a number of slips and the like stored at the bank for later work. Conventionally, as shown in FIG. 2, a medium insertion slot is provided for each of a passbook / form and a slip, and one type of printing medium is shared by two types of media, and the medium is transported to each insertion slot. A passbook processing device which enables parallel processing and interrupt processing is used.

In recent years, as shown in FIG. 3, a passbook processing apparatus of a type equipped with an independent medium transport path and a printing section for a passbook and a slip has begun to be used. In the case of a passbook processing apparatus in which one medium is shared by two types of media as in the former case, when two types of media are inserted into their respective insertion slots, while one medium is being printed by the printing unit, the other medium is It takes a long time to process two media in a waiting state, and if one is interrupted while the other is being processed, one must be temporarily saved, which is not suitable for speeding up the processing.

On the other hand, in the latter case, a passbook processing apparatus equipped with an independent medium transport path and a printing section for a passbook and a slip can execute processing completely in parallel, thereby realizing high-speed processing. Is possible.

[0007]

However, since the printing section of the latter passbook processor is a serial printer which performs printing by reciprocating in the width direction of the medium with a heavy dot impact head, the printing head is activated. And the stop causes shaking. Although the shaking caused by the individual print heads is not so noticeable, when the start and stop operations of a plurality of print heads overlap, the shaking of the entire apparatus is greatly amplified.

Generally, a desk for operator's work is installed adjacent to a passbook processing device installed in a financial institution.
Excessive shaking of the device interferes with the work of the operator.
Further, there is a problem that this fluctuation adversely affects peripheral devices of the passbook processing apparatus. SUMMARY OF THE INVENTION It is an object of the present invention to use a passbook processing apparatus equipped with a plurality of print heads to speed up the processing of the entire apparatus and to reduce the shaking of the apparatus to achieve a stable passbook processing.

FIG. 1 is a diagram illustrating the principle of the present invention. Reference numeral 1 denotes a print control unit, which edits print data received from a host device such as a work station to control a printing operation, and 2 denotes a time counting unit, which counts a time from start to stop of the print head by a timer. And 3A
Is a print head, which prints on the medium A, 4A is a medium transport means, which transports the medium A to a print position, and 5A is a print head moving means, which moves the print head 3A.

Reference numeral 3B denotes a print head, which prints on the medium B, 4B denotes a medium transport means, which transports the medium B to a print position, and 5B, a print head moving means, which moves the print head 3B. Reference numeral 6 denotes communication means for communicating print information on the medium A and the medium B.

[0011]

When the medium A is conveyed by the medium conveying means 4A, the host device instructs the print control means 1 to print on the medium A by the print head 3A. At that time, the other print head 3B
Is checked by using the communication means 6 to determine whether or not is being moved by the print head moving means 5B.

As a confirmation method, when the print head 3B is started, the time from start to stop is counted by the time counting means 2.
If the time counting means 2 is counting, it is determined that the print head 3B is moving, and if the time counting means 2 is not counting, the print head 3B is determined not to be moving. . When the print head 3B is not moving, that is, when the time counting means 2 is not counting, the print control means 1 performs printing with the print head 3A as usual.

The sway caused by the print head becomes large when the sway caused by the start and stop of one print head and the sway caused by the start and stop of the other print head overlap.
FIG. 4 is a diagram illustrating a mode of shaking due to the start and stop of the print head. The horizontal axis represents the magnitude of the shaking, and the vertical axis represents the time. T is a time interval from the start of the start or stop operation of the print head to the convergence of the shake, and is a constant inherent to the structure of the apparatus, and can be easily obtained by a simple experiment using a prototype or the like.

When the print head 3B is moving, that is, when the time counting means 2 is counting, the printing control means 1
Calculates the time when the print head 3A swings due to the start and stop of the print head 3A from the print content of the print head 3A, reads the time when the other print head 3B shakes due to the start and stop of the other print head 3B through the communication means, and In the case where at least one shake caused by the start and stop and the shake caused by the start and stop of the other print head 3B overlap, the start operation of the print head 3A is delayed to prevent the shake from increasing.

According to a second aspect of the present invention, the medium transport means
When the medium A is transported by A, the host device instructs the print control means 1 to print on the medium A by the print head 3A, and the print control means 1
B is being moved by the print head moving means 5B,
That is, the time counting means 2 set in the other print head
Is checked by the communication means 6 and if the print head 3B is not moving, that is, if the time counting means 2 is not counting, printing is performed by the print head 3A as usual.

When the print head 3B is moving, that is, when the time counting means 2 is counting, the printing control means 1
After the printing of the line currently being printed by the print head 3B is completed, the print head 3A and the print head 3B are moved away from the center of gravity of the apparatus by the print head moving means 5A and the print head moving means 5B. Move it closer.

FIG. 5 is a diagram showing the movement of the print head 3A and the print head 3B for canceling the shaking. The vertical axis is time,
The horizontal axis indicates the position from the center of gravity of the device. When each print head moves to the print position, the print control means 2 adjusts the print speed of the print head 3A and the print head 3B to the slower one and simultaneously toward the center of gravity of the apparatus or simultaneously toward the side away from the center of gravity of the apparatus. To perform the printing operation.

A line feed is also performed at the same time, and when the line feed amount is different, a time-consuming one is waited, and a printing operation is performed again simultaneously toward a direction away from the center of gravity of the apparatus or simultaneously toward a center of gravity of the apparatus. This operation is continued during a time interval when both printing operations overlap. The same operation is performed when the print head 3B is activated.

The simultaneous printing of the two heads with the center of gravity as the center cancels the shaking, thereby preventing the shaking of the apparatus from increasing.

W is the time during which one of the print heads is about to start printing while the other print head is moving, and x is the time during which the shaking due to activation when the other print head starts printing at w is converged. In this case, y is the time during which the print head stops, and z is the time during which the shaking during stop converges.

If any one of the time intervals of 0 to s, u to v, w to x, and y to z overlaps each other, it may cause excessive amplification of the fluctuation. FIG. 9 is a flowchart of the control of the CPU according to the first embodiment of the present invention. The first embodiment will be described with reference to FIGS.

Check whether 4B is moving. (Step 32) As a confirmation method, when the other print head 14B is activated, the print head 1B is moved during the movement time of the print head 14B.
The CPU 11A counts the time obtained by adding the time until the shaking at the time of stoppage of 4B to the convergence to the programmable timer 12B, so that the CPU 11A sets the programmable time set on the other print head 14B through the signal lines 21A and 21B. The timer 12B is read, and if the programmable timer 12B is counting, the other print head 14B is moving. If the programmable timer 12B is not counting, the other print head 1B is being counted.
4B determines that it is not moving.

When the other print head 14B is not moving, that is, when the programmable timer 12B is not counting, the CPU 11A converges the shaking at the time of starting the print head 14A from the moving direction and the moving distance of the edited print data. The time s, the time u during which the print head stops, and the time v during which the oscillation when the print head stops converge are calculated (step 33), and the time T until the oscillation when the stop stops during the moving time of the print head 14A is calculated. Added time, ie 0-v

The print head 14A is moved by 6A to perform one-line printing. (Step 35) When the printing of one line is completed, it is confirmed whether or not the printing of all the lines is completed (Step 36). When the printing is not completed, the process returns to Step 31 and the printing is performed line by line.

In step 32, the other print head 1
If 4B is moving, the CPU 11A sets the signal line 21
A, the other programmable timer 12B through 21B
Is read (step 37), and when the other print head 14B starts and stops, the shaking during the time period 0 to s,
Read u ~ v. (Step 38) The CPU 11A calculates the time sections w to x and y to z during which the print head 14A starts up at w and where the shaking at the time of stoppage continues. (Step 39) It is checked whether at least one of the time sections of 0 to s, u to v, w to x, and y to z overlaps (Step 40). If they do not overlap, w is set to 0 and x is set to s and y. Is calculated from 0 to s and u to v with u and z being v (step 33), and the time obtained by adding the time T required for the movement of the print head 14A to converge the shaking when the print head 14A stops, that is, 0 to v are set in the programmable timer 12A and counted (step 34), the print head 14A is activated, the head pins are driven by the head pin driving circuit 15A, and the space motor driving circuit 17A and the space motor 1 are driven.
The print head 14A is moved by 6A to perform one-line printing. (Step 35) In step 40, 0 to s, u to v, w to x, and y to z
If at least one time section overlaps, the CPU
11A continues reading the value w of the other programmable timer 12B through the signal lines 21A and 21B (step 3).
7), the time periods 0 to s and u to v during which the shaking when the other print head 14B starts and stops are read (step 3).

Activate the print head 14A and set the head pin drive circuit 1
The head pins are driven by 5A, and the print head 14A is moved by the space motor drive circuit 17A and the space motor 16A to perform one-line printing. (Step 3
5) The speed of the printing process on a plurality of media can be increased by the control of the CPU, and the amplification of the shaking during the start / stop operation of the plurality of print heads can be prevented.

When printing on the medium B, the same control is performed by the CPU 11B. FIG. 10 is a flowchart of the control of the CPU according to the second embodiment of the present invention. A second embodiment will be described with reference to FIGS. CPU11
A receives a print request from a host device such as a workstation (step 41), and receives the medium A from the host device based on the fact that the medium A has been transported to the printing unit by the transport control circuit 20A and the transport motor 19A. The print data is edited into actual print data (step 42), and it is confirmed through the signal line interfaces 21A and 21B whether the other print head 14B is moving. (Step 43) As a method of confirmation, when the other print head 14B is activated, the print head 1 is moved during the movement time of the print head 14B.
The CPU 11A counts the time obtained by adding the time until the shaking at the time of stoppage of 4B to the convergence to the programmable timer 12B, so that the CPU 11A sets the programmable time set on the other print head 14B through the signal lines 21A and 21B. The timer 12B is read, and if the programmable timer 12B is counting, the other print head 14B is moving. If the programmable timer 12B is not counting, the other print head 1B is being counted.
4B determines that it is not moving.

FIG. 11 is a diagram showing the movement of the print head 14A and the print head 14B when the other printing head 14B is moving. The horizontal axis represents the center of gravity from the device, and the vertical axis represents time. If the other print head 14B is moving, that is, if the programmable timer 12B installed on the other print head 14B is counting, C
The PU 11A requests the other CPU 11B for anti-sway printing via the signal line interfaces 21A and 21B.
(Step 44) Here, the anti-shake printing cancels the shaking of both print heads by simultaneously moving both print heads toward the center of gravity of the apparatus or simultaneously moving away from the center of gravity of the apparatus. Refers to printing.

After the other print head 14B completes the printing operation of the line currently being printed and waits for a time interval T at which the shaking at the time of stoppage converges, that is, the programmable timer 12B set in the print head 14B counts. When the completion of the operation is notified via the signal line interfaces 21A and 21B (step 45), the CPU 11A sets a programmable timer to a time obtained by adding a time T until the shaking at the time of stop to the moving time of the print head 14A converges. The print head 1 is set to 12A and counted (step 46).
4A is moved to the shake prevention printing start position by the space motor 16A and the space motor drive circuit 17A. (Step 47) Here, the swing-prevention printing start position is a position where both print heads are farthest away from or closest to the center of gravity of the apparatus.

The CPU 11A waits for a time interval T when the print head 14A has finished moving and the shaking during stoppage has converged, that is, the signal line interfaces 21A and 21B indicate that the programmable timer 12A has finished counting.
(Step 48), the other CPU 11 is notified via the signal line interfaces 21A and 21B.
B is notified to move the print head 14B to the shake start print start position. (Step 49) When the respective print heads are moved to the print start position, the above-described sequence is performed, thereby preventing an increase in the swing of the print head at the time of starting and at the time of stopping.

After the other print head 14B has finished moving,
After waiting for the time interval T at which the shaking at the time of stop converges, that is, when the programmable timer 12B set in the print head 14B is notified via the signal line interfaces 21A and 21B that the counting has been completed (step 5).
0), the CPU 11A starts the shake prevention printing.
Informing B, the print heads 14A and 14B perform printing simultaneously toward the center of the apparatus or simultaneously toward the direction away from the center of the apparatus. (Step 5
1) When printing is completed for both, the anti-shake printing ends.
(Step 52) If the other print head 14B is not printing in step 43, the CPU 11A adds, to the programmable timer 12A, the time obtained by adding the time interval T until the shaking at the time of stoppage converges to the movement time of the print head 14A. It is set and counted (step 53), and printing is performed line by line as usual (step 54). When the other CPU 11B receives a notification of a print request for preventing vibration (step 55), the print head 14A prints the current data. After finishing the printing operation for the line that is
That is, after the count of the programmable timer 12A is completed (step 56), the process proceeds to step 46 to perform the anti-shake printing.

In step 55, the other CPU 11B
If there is no notice of the print to prevent the fluctuation, the CPU 11A
Repeats one-line printing as usual, and ends printing.
(Step 57) By the control of the CPU, the shaking due to the movement of the print heads on both medium sides is cancelled, and a high-speed and shaking-free printing process can be realized.

The same control is performed by the CPU 11B when printing on the medium B. In the first embodiment and the second embodiment, a signal line interface is used as communication means of print information. However, a higher-level device such as a workstation receives print information from one CPU, and receives the other CPU.
, It is also possible to communicate between CPUs.

In the first and second embodiments, a plurality of printing units are respectively controlled by a plurality of CPUs, but a plurality of printing units may be controlled by a single CPU.
In this case, the program becomes complicated, but there is no need to provide communication means for communicating the print information of each printing unit.
In the first and second embodiments, the CPU of the printing unit controls the printing, and the signal line interface is used as the communication unit. However, the workstation can perform the printing control and the communication of the printing information. It is.

The workstation 22 reads the programmable timer 12B set on the other print head 14B, and counts the time obtained by adding the time until the shaking when the 4B stops to converge to the programmable timer 12B. If the timer 12B is counting, it is determined that the other print head 14B is moving, and if the programmable timer 12B is not counting, it is determined that the other print head 14B is not moving.

Then, the head pins are driven by the head pin drive circuit 15A, and the print head 14A is moved by the space motor drive circuit 17A and the space motor 16A to perform one-line printing.
(Step 65) When the one-line printing is completed, it is checked whether or not all the printing is completed (step 66). If not completed, the process returns to the step 61 to print one line at a time.

In step 62, the other print head 1

x, y to z are calculated. (Step 69) It is checked whether at least one time section of 0 to s, u to v, w to x, and y to z overlaps (step 70). If they do not overlap, w is 0 and x is s, y. Is calculated as u and z and v as 0 to s and u to v (step 63), and the time obtained by adding the time T until the shaking when the print head 14A stops at the moving time of the print head 14A, that is, 0 to v are set in the programmable timer 12A and counted (step 64), the print head 14A is activated, and the head pins are driven by the head pin drive circuit 15A, and the space motor drive circuit 17A and the space motor 1 are driven.

Ｖv are read (step 68), and time sections w〜x, yz are continued (step 69) in which the print head 14A is activated at the time of starting at the time of starting and stopping and stopping (step 69).
After confirming that at least one of the time sections of u to v, w to x, and y to z does not overlap (step 70), w is set to 0,
x is s, y is u, and z is v, 0 to s and u to v are calculated (step 63), and the time T until the shaking at the time of stoppage converges to the movement time of the print head 14A is calculated by: That is, 0 to v are set in the programmable timer 12A and counted (step 64), the print head 14A is activated, the head pins are driven by the head pin drive circuit 15A, and the print head is driven by the space motor drive circuit 17A and the space motor 16A. 14A is moved to perform one-line printing. (Step 65) By controlling the work station 22, the speeding up of the printing process for a plurality of media can be realized, and the amplification of the shaking during the start / stop operation of the plurality of print heads can be prevented.

The same control is performed by the workstation when printing on the medium B. Next, a fourth embodiment in which printing control and communication of print information in the second embodiment are performed by a workstation will be referred to as a fourth embodiment. FIG. 13 is a flowchart of the control of the workstation in the fourth embodiment.

(Step 73) As a method of confirmation, when the other print head 14B is activated, the print head 1B is moved during the movement time of the print head 14B.
The workstation 22 reads the programmable timer 12B set on the other print head 14B, and counts the time obtained by adding the time until the shaking when the 4B stops to converge to the programmable timer 12B. If the timer 12B is counting, it is determined that the other print head 14B is moving, and if the programmable timer 12B is not counting, it is determined that the other print head 14B is not moving.

When the other print head 14B is moving, that is, when the programmable timer 12B set in the other print head 14B is counting, the work station 22 is currently printing by the other print head 14B. After the end of the printing operation of the line, after waiting for a time interval T at which the shaking at the time of stop converges, that is, the print head 14B

And the print head 14B prints simultaneously toward the center of the apparatus, or simultaneously, away from the center of the apparatus. (Step 80) When the printing is completed for both, the anti-shake printing ends.
(Step 81) If the other print head 14B is not printing in step 73, the workstation 22 sets the programmable timer to the time obtained by adding the time interval T until the shaking at the time of stoppage converges to the moving time of the print head 14A. 12A and counting (Step 82), printing is performed line by line as usual (Step 83), and the other print head 1 is printed.
If the print data to be printed in 4B has been edited (step 84), the print head 14A completes the printing operation of the line currently being printed, and the time interval T at which the shaking at the time of stop converges is converged.
After waiting for a while, i.e., after the programmable timer 12A has finished counting (step 85), the flow proceeds to step 75 to perform anti-sway printing.

In step 84, the other print head 1
If the print data printed in 4B is not edited,
The work station 22 repeats one-line printing with the print head 14A as usual, and ends printing. (Step 8
6) The control of the work station 22 cancels the shaking caused by the movement of the print heads on both medium sides, and realizes a printing process at high speed and without shaking.

The same control is performed by the workstation when printing on the medium B.

[0047]

According to the present invention, in a printing apparatus having a plurality of print heads, since the swings at the time of starting and stopping the print heads do not overlap, it is possible to realize a printing apparatus which is high-speed and has little swing of the apparatus. Becomes possible. In addition, when a plurality of print heads perform printing simultaneously, printing is performed in a direction that cancels out the shaking caused by the print heads, so that it is possible to realize a printing device that is fast and does not shake during the printing operation.

By using the above-described printing apparatus, it is possible to reduce the adverse effect of vibration applied to machines and people around the printing apparatus.
