Description

[Detailed Description of the Invention] [Summary] When the printable lines of a print medium such as a bankbook are set, if one of the front and rear feed rollers of the printer section does not hold the bankbook, reciprocating printing is performed in one direction. The purpose of the present invention is to provide a printer that can switch to print by switching to the printer, and to provide a printer that can prevent line-by-line printing misalignment due to reciprocating printing. a conveyance path having a guide surface on which one end surface of the inserted print medium is guided and a plurality of feed rollers through which the print medium is conveyed; The printer is equipped with a printing device that performs reciprocating printing on a unit, and when a printable line is set at the position of the printing device, a pair of feeding rollers arranged before and after the printing device among the plurality of feeding rollers Both include detection means for detecting whether or not the print medium is being held between them, and when it is detected that either one of the pair of feed rollers is not holding the print medium, printing reciprocating printing in the direction of the guide surface. A switching control means for switching to unidirectional printing is provided, and the switched unidirectional printing is continued until one of the feed rollers that was not nipping the print medium nip it.

[Industrial application field]

The present invention relates to a printer that prints on print media such as passbooks, and particularly when one of the front and rear feed rollers of the printer unit is not holding the print medium when the printable line of the print medium is set in the printer unit. relates to a printer that can switch from reciprocating printing to unidirectional printing.

Recently, automatic deposit payment machines (
Automatic Teller Machine:
Automated transaction devices such as ATMs (hereinafter referred to as ATMs) and counter-recording machines operated by tellers have a built-in passbook printer that records transaction details in a passbook, etc., and reads the already printed lines of the passbook inserted into the device and prints out the information. Transaction processing and bookkeeping are performed after setting possible lines in the printer section.

In this case, printing is performed back and forth line by line, but when it is set in the printer unit, depending on the number of lines that have already been printed, one of the feed rollers at the front and back of the printer unit may not be holding the passbook, etc. Since the reciprocating printing causes printing misalignment from line to line, a method for preventing printing misalignment is desired.

[Conventional technology]

As shown in Fig. 4, the bookkeeping machine includes a device main body 3 equipped with an insertion slot 2a into which a passbook 1a is inserted, a keyboard 4 for inputting the customer's account number, transaction details, etc., and a keyboard 4 for displaying operation processing details, etc. It is composed of a display 5 and a display 5. The device main body 3 is connected to a host computer (hereinafter referred to as host), which is not shown. Also, Fig. 5(a) and O)
) are a side view and a plan view of the passbook printer, showing a conveyance path 6a that continues from the insertion slot 2a into which the passbook 1a is inserted, and a read/write device that reads recorded data from the magnetic stripe of the passbook 1a.
(hereinafter referred to as R/W) Part 7. Printer section 8a + passbook 1a
Feed roller RI "" R3 + presser roller R
a to Rb, sensors Sl for detecting the leading and trailing ends of the inserted passbook 10a, S2. A reading sensor S3 is provided to detect page marks and printed lines. Printer section 8
A is composed of a print head 80 having a print mask 81 on the front side and a platen 82. Also, the feed roller R,
-R3 is connected to pulse motor M1.

With such a structure and function, the teller can use the passbook 1.
When a is inserted from the insertion slot 2a in the direction of arrow A while touching one end surface to the guide surface 60a, the sensor S1 detects the tip, the pulse motor 1 is driven and conveyance is started, and the passbook 1a is inserted into the passbook 1a.
The record data of the account number and balance are read by the R/W section 7, and the sensor S2 is further conveyed until the rear end of the passbook 1a is detected. During this time, the reading sensor S3 reads the record data of the passbook 1a.
It recognizes the page mark printed near the tip of the line, reads the hyphen on the already printed line, moves the number of steps from the last line to the printable line, and conveys the printable position to the printer section 8a to set the line. .

Next, when the teller inputs transaction data from the keyboard 4, it is sent to the host along with record data such as account number and balance amount, is processed, bookkeeping data, etc. is responded, and is sent to the printer section 8a.
Transaction data including the deposit balance is printed on the passbook 1a. When printing extends over multiple lines, reciprocating printing is performed to increase the printing processing speed.

When printing is completed, the passbook 1a is sent in the direction of arrow B, and then
/W section 7 writes the balance data of the transaction results into a magnetic disk drive, and the data is ejected from the insertion slot 2a.

In this way, the bankbook 1a is recorded by the bankbook printer.

[Problem to be solved by the invention]

According to the above conventional method, when printing on the passbook 1a,
As shown in FIG. 6(a), the passbook 1a is normally pressed against the printing mask 81 by a platen pressure of about 1 kg, and due to reciprocating printing, the passbook 1a always receives a force that moves in the printing direction, and this is transferred to the conveyance path. Movement is prevented by the guide surface 60a, front and rear feed rollers R2, R3, and presser rollers R5 and R6, and even when printing in a direction away from the guide surface 61a, there is a slight movement (for example, 0.1-0.2 mm).
It is within the acceptable range.

However, the lines near the front or back edge of the page (
For example, when the passbook 1a is set (within 3 lines), a state occurs in which either the pair of front and rear feed rollers R2, R3 and presser rollers R5, R6 do not hold the passbook 1a.

FIG. 6(b) shows a case where the front end of the bankbook 1a is set and the bankbook 1a is not held between the feed roller R3 and the pressing roller R6. Feed roller R2 and feed roller R3
A predetermined distance is required for the print head 80 and the head mask 81 to print in the horizontal direction, and in particular, in the case of a color printing printer, this distance is required because a wide ink ribbon is used. I have no choice but to take it broadly.

Therefore, when the passbook 1a is held between the front and back of the printer section 8a, as shown in FIG. As a result, the movement of the passbook 1a due to reciprocating printing cannot be prevented, and it becomes easier to move when the humidity is high, resulting in even greater printing deviation, as shown in Figure 6 (
As shown in C), there is a problem in that printing misalignment (for example, about 1 mm) occurs and print quality deteriorates.

SUMMARY OF THE INVENTION An object of the present invention is to provide a printer that can prevent line-by-line printing misalignment due to reciprocating printing.

[Means to solve the problem]

FIG. 1 is a diagram showing the principle configuration of the present invention, and (a) is a side view.

[Yes]) is a plan view.

In the figure, 1 is a print medium, 2 is an insertion port, 6 is a conveyance path,
8 is a printing means, 60 is a guide surface, 61 is a feed roller, and 13 is a plurality of feed rollers 61 before and after the printing means 8 when the printable line of the print medium 1 is set at the position of the printing means 8. Detection means 14 detects whether or not the pair of arranged feed rollers 61 are pinching the print medium 1; 14 is a detection means 13 that detects whether one of the pair of feed rollers 61 is pinching the print medium 1; This is a switching control means that switches reciprocating printing by the printing means 8 to unidirectional printing in which printing is performed in the direction of the guide surface 60 when it is detected that there is no guide surface 60 .

Therefore, the one-way printing switched by the switching control means 14 is continued until the one feed roller 61 that was not nipping the printing medium 1 nipping the printing medium 1.

[Effect]

When the printable line of the printing medium 1 is set at the position of the printing means 8, the detection means 13 detects that one of the pair of feed rollers 61 disposed before and after the printing means 8 is not nipping the printing medium 1. When detected, based on the detection output, the switching control means 14 switches the reciprocating printing by the printing means 8 to unidirectional printing in which printing is performed in the direction of the guide surface 60, and the one feed roller that was not holding the printing medium 1 is switched. Unidirectional printing is continued until the printing medium 1 is sandwiched between the printing media 61 and the printing medium 1.

In this way, when either one of the feed rollers arranged before or after the printing means 8 is not holding the printing medium 1, unidirectional printing is performed in the direction of the guide surface 60, thereby preventing printing misalignment. It is possible to improve printing quality.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 2 and 3. The same reference numerals indicate the same objects throughout the figures.

Passbook 1a + printer section 8a+ and switching control section 1 in Fig. 2
4a is the print medium 1. of FIG. Printing means 8. and the switching control means 14, respectively, and the unidirectional printing line table 13a and determination section 13b in FIG. 2 correspond to the detection means 13 in FIG.

The present invention relates to controlling the printing direction in the printer section 8a for the bankbook 1a, and the mechanism is the same as that shown in FIG. 5.

FIG. 2 shows a block diagram of a passbook printer showing an embodiment of the present invention.

In the figure, the conveyance control unit 9 rotates the motor M1 based on the detection and reading of the front/back edge and printed lines of the passbook 1a by the sensors 51, 52 and the reading sensor S3, and drives the feed rollers R1 to R3. and controls the suction of the passbook 1a and the discharge of the set of printable lines.

The line data memo January O stores the number of hyphens in the already printed lines read by the reading sensor S3, that is, the number of already printed lines.

The line editing unit 11 edits the number of steps from the last line to the printable line of the passbook 1a based on the number of printed lines stored in the line data memory 10.

The print control unit 12 controls the print head 80 and the space motor M2.

The one-way printing line table 13a is a memory in which the number of lines to be printed in one direction on the front end and rear end of the passbook 1a is set. For example, assuming that the number of lines from the front end to the back end of the passbook 1a is 20, Three lines at the front end, ie, lines 1 to 3, and three lines at the rear end, ie, lines 18 to 20, are stored.

The determining unit 13b determines whether or not the line data stored in the line data memory 10 is within the number of lines set in the unidirectional printing line table 13a, and if the number of lines is not present, a signal a is sent.
When there is, a signal is sent to the main control section 19. Then, each time subsequent line printing is performed, the search for the set number of lines in the unidirectional printing line table 13a is repeated using the updated line data in the line data memory 10.

The switching control section 14a receives a signal a sent from the main control section 19.
, b, the print controller 12 is instructed to perform reciprocating printing when the signal is a, and to perform unidirectional printing when the signal is ``s''.

The main control section 19 controls each section to inhale the passbook 1a.

Performs bookkeeping processing such as control of sending, reciprocating printing, and unidirectional printing, and in particular counts the number of already printed lines read by the reading sensor S3 and stores them in the line data memo 1 month O, and finishes printing of the - line. Each time, the data in the row data memory 10 is updated by +1.

Also, 15 is a sensor amplifier, and 16.17 is a motor driver.

18 indicates a head driver.

Since it has such a configuration and function, the operation will be explained next with reference to the flowchart shown in FIG.

■First, when the passbook 1a is inserted through the insertion slot 2a, the conveyance control unit 9 is activated by the detection of the sensor Sl, and the feed rollers R1 to R3 are rotated by the drive of the motor, and the passbook 1a is conveyed. Recorded data is read from the magnetic stripe in the W section 7.

(2) The gla is further conveyed, and the leading and trailing ends are detected by the sensor S2, and the already printed lines are read by the reading sensor S3, so that the already printed line data is stored in the line data memo January 0.

(2) The line editing section 11 edits the number of transfer steps based on the already printed line data and issues a transfer command to the transfer control section 9.

(2) The conveyance control section 9 rotates the pulse motor M1 by the instructed number of steps, moves the bankbook 1a by driving the feed rollers R1 to R3, and sets printable lines in the printer section 8a.

(2) Then, when the operator inputs data such as the transaction amount from the keyboard 4, the main control section 19 communicates with the host and receives response data to be recorded.

(2) Then, the enactment unit 14a searches whether the already printed line data in the line data memory 10 is within the number of lines set in the unidirectional printing line table 13a.

(2) When there is no already printed line data within the set number of lines, the determination unit 13b notifies the main control unit 19 of a signal a.

Then, the main control section 19 sends a signal a to the switching control section 14a, and the switching control section 14a causes the printing control section 12 to perform normal printing (
(one side during reciprocating printing).

(2) Next, the main control section 19 sends response data to the print control section 12, and printing is performed during one of the two-way printing.

(2) Also, when there is already printed line data within the set number of lines, the determination unit 13b sends a signal to the main control unit 19. Then, a signal is sent from the main control section 19 to the switching control section 14a, and the switching control section 14a instructs the printing control section 12 to perform unidirectional printing.

[Phase] Next, the main control section 19 sends response data to the print control section 12, and unidirectional printing is performed. That is, printing is performed from the right end of the passbook 1a toward the guide surface 60a.

■When the book entry is completed by printing that line in the above ■ or [phase], the bankbook 1a is sent to the R/W section 7, the balance amount is recorded on the magnetic step, and the bankbook 1a is sent to the insertion slot 2a.

When the passbook 1a is returned and the detection by the sensor Sl is canceled, the row data memory 10 is cleared.

@When the data to be printed extends to the next line, the main control unit 19
is incremented by 1 to the row data in the row data memory 10 and stored in the row data memory 10 again, and then a line feed is performed.

■Then, the flow after ■ is repeated.

In this way, for example, lines 1 to 3 at the tip of the passbook 1a
When the line is a printable line, it is not held between the feed roller R3 and the presser roller R6, so printing is performed in one direction at first, but by printing multiple lines, from the fourth line onwards, printing is performed in one direction. Since it is held between the feed roller R3 and the presser roller R6, reciprocating printing is performed.

For example, when the 17th line or earlier at the rear end of the passbook 1a is a printable line, reciprocating printing is performed at first, but when the 18th line is reached due to multiple lines of printing, the feed roller R2
Since the holding roller R5 is released, the printing can be switched to unidirectional printing.

〔Effect of the invention〕

As explained above, according to the present invention, when the printable line of the passbook is set at the position of the printing means, if either one of the feed rollers arranged before or after the printing means is not holding the passbook, Since unidirectional printing can be performed in the direction of the guide surface of the conveyance path, it is possible to prevent printing misalignment from line to line due to reciprocating printing.
