[Industrial applications]

The present invention relates to a printer that prints on a print medium such as a passbook, and particularly when a printable line of the print medium is set in the printer unit and one of feed rollers before and after the printer unit does not hold the print medium. The present invention relates to a printer capable of switching reciprocating printing to one-way printing for printing.

2. Description of the Related Art In recent years, automatic teller machines such as automatic teller machines (hereinafter referred to as ATMs) used at financial institutions, and teller machines operated by tellers include passbook printers for recording transaction contents in passbooks and the like. The transaction processing and bookkeeping are carried out after reading the already printed lines of the passbook inserted into the apparatus and setting the printable lines in the printer unit.

In this case, printing is performed in a reciprocating manner on a line basis.
In some cases, one of the feed rollers before and after the printer unit does not pinch a passbook or the like, and a reciprocal printing causes a printing deviation for each line. Therefore, a method for preventing the printing deviation is desired.

[Conventional technology]

As shown in FIG. 4, the bookkeeping machine displays an apparatus main body 3 having an insertion slot 2a into which a passbook 1a is inserted, a keyboard 4 for inputting a customer's account number and transaction details, operation processing details, and the like. And a display 5. The apparatus main body 3 is connected to a host computer (hereinafter, referred to as a host) not shown. 5 (a) and 5 (b) are a side view and a plan view of the passbook printer, respectively. FIG. 5 is a perspective view of the passbook 1a. hereinafter referred to R / W) unit 7, the feed roller R ₁ to transfer printer unit 8a, a passbook 1a
RR ₃ , holding rollers R ₄ RR ₆ , sensors S1 and S2 for detecting the leading and trailing ends of the inserted passbook 10a, and reading sensors S3 for detecting page marks and printed lines. Printer section 8a
The print head 80 includes a print head 80 having a print mask 81 on the front surface and a platen 82. The feed roller R ₁ to R ₃ is connected to the pulse motor M1.

With such a configuration and functions, tellers can passbook
When 1a is inserted in the direction of arrow A from the insertion opening 2a while one end face is brought into contact with the guide surface 60a, the sensor S1 detects the leading end, the pulse motor M1 is driven, and the conveyance is started. The record data such as the account number and balance is read by the sensor, and it is transported until the rear end of the passbook 1a is detected by the sensor S2. During this time, the read sensor S3 recognizes the page mark printed near the front end of the passbook 1a. At the same time, the hyphen of the already printed line is read, the number of steps from the last line to the printable line is moved, and the printable position is conveyed to the printer unit 8a to set the line.

Next, when the teller inputs the transaction data from the keyboard 4, the data is sent to the host together with the record data such as the account number and the balance, and is processed.
As a result, the transaction data including the deposit balance and the like is printed on the passbook 1a. When printing is performed over a plurality of lines, reciprocating printing is performed to increase the printing processing speed.

When printing is completed, the bankbook 1a is sent in the direction of arrow B,
The W unit 7 writes the balance data of the transaction result on the magnetic stripe and discharges it from the insertion port 2a.

In this manner, the passbook 1a is recorded by the passbook printer.

[Problems 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 print mask 81 by a platen pressure of about 1 kg. Guide surface 60a and front and rear feed rollers R
Movement is prevented by 2, R3 and holding rollers R5, R6.
Even when printing is performed in a direction away from the guide surface 61a, it is slightly moved (for example, 0.1 to 0.2 mm), which is within the allowable range.

However, when a line (for example, within three lines) near the front end or the rear end of the page is set, one of the pair of front and rear feed rollers R2, R3 and the pressing rollers R5, R6 sandwiches the passbook 1a. Missing condition occurs.

FIG. 6B shows a case where the front end of the passbook 1a is set, and the feed roller R3 and the pressing roller R6 do not sandwich the passbook 1a. The distance between the feed roller R2 and the feed roller R3 requires a certain amount of space for the print head 80 and the head mask 81 to print in the horizontal direction, and especially for color printing printers, use a wide ink ribbon. To do
This interval must be widened.

Accordingly, when only one of the passbooks 1a is sandwiched before and after the printer unit 8a, as shown in FIG. Occurs, and the bankbook 1a
6c cannot be prevented, and it is easy to move when the humidity is high. Therefore, the printing deviation further increases, and as shown in FIG. 6C, the printing deviation (for example, about 1 mm) occurs, and the printing quality deteriorates. There is a problem that.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a printer capable of preventing a print deviation from line to line due to reciprocal printing.

[Means for solving the problem]

FIG. 1 is a diagram showing the principle of the present invention, wherein FIG.
(B) is a plan view.

In the figure, 1 is a printing medium, 2 is an insertion slot, 6 is a conveying path, 8 is a printing means, 60 is a guide surface, 61 is a feed roller, and 13 is a printable line of the printing medium 1 set at the position of the printing means 8. The printing means 8 in the plurality of feed rollers 61
Detecting means for detecting whether or not any of the pair of feed rollers 61 arranged before and after is holding the print medium 1; and 14, detecting means 13 for detecting one of the print media 1 of the pair of feed rollers 61 Switching control means for switching reciprocal printing by the printing means 8 to one-way printing in which printing is performed in the direction of the guide surface 60 when it is detected that the sheet is not nipped.

Therefore, the one-way printing switched by the switching control means 14 is configured to be continued until one of the feed rollers 61 that has not sandwiched the print medium 1 sandwiches the print medium 1.

[Action]

When the printable line of the printing medium 1 is set at the position of the printing means 8, the detecting means 13 determines that one of the pair of feed rollers 61 disposed before and after the printing means 8 does not hold the printing medium 1. Upon detection, reciprocal printing by the printing means 8 is performed by the switching control means 14 based on the detection output,
The one-way printing is switched to the one-way printing in which the printing medium 1 is not nipped, and the one-way printing is continued until one of the feed rollers 61 that has not nipped the printing medium 1 has nipped the printing medium 1.

In this way, when one of the feed rollers arranged before and after the printing means 8 is not holding the print medium 1, one-way printing in the direction of the guide surface 60 is performed to prevent printing deviation. Printing quality can be improved.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 2 and 3. The same reference numerals indicate the same objects throughout the drawings.

The passbook 1a, the printer unit 8a, and the switching control unit 14a in FIG.
Are the printing medium 1, printing means 8, and switching control means 14 shown in FIG.
The one-way print line table 13a and the determination unit 13b in FIG. 2 correspond to the detecting means 13 in FIG.

The present invention relates to the control of the printing direction of the passbook 1a in the printer unit 8a, and the mechanism is the same as that of FIG.

FIG. 2 is 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 / rear ends of the passbook 1a and the already printed lines of the sensors S1 and S2 and the reading sensor S3, and
To R3 to control the inhalation of the passbook 1a and the discharge of the printable line set.

The line data memory 10 stores the number of hyphens in the printed line read by the reading sensor S3, that is, the number of printed lines.

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

The print control unit 12 includes a print head 80 and a space motor M2.
To control the drive of.

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

The determination unit 13b determines whether or not the line data stored in the line data memory 10 is in the number of lines set in the one-way printing line table 13a.If the number of lines is not present, the signal a is output.
If there is, the signal b is sent to the main control unit 19. Each time subsequent line printing is performed, the search for the set number of lines in the one-way print line table 13a is repeated with the updated line data in the line data memory 10.

The switching control unit 14a instructs the print control unit 12 to perform reciprocal printing for the signal a and one-way printing for the signal b based on the signals a and b sent from the main control unit 19.

The main control unit 19 controls each unit to perform a bookkeeping process such as inhalation, delivery, reciprocal printing and one-way printing control of the passbook 1a, and in particular, counts the number of already printed lines read by the reading sensor S3. The data is stored in the line data memory 10 and is updated by incrementing the data in the line data memory 10 by one each time printing of one line is completed.

Reference numeral 15 denotes a sensor amplifier, reference numerals 16 and 17 denote motor drivers, and reference numeral 18 denotes a head driver.

Having such a configuration and function, the operation will be described next with reference to the flowchart of FIG.

First, when the passbook 1a is inserted from the insertion slot 2a, the sensor S1
Then, the transport control unit 9 is activated, the feed rollers R1 to R3 are rotated by the driving of the motor M1, the passbook 1a is transported, and the recording data is read from the magnetic stripe by the R / W unit 7.

The passbook 1a is further conveyed, and the printed line data is stored in the line data memory 10 by detecting the leading and trailing ends by the sensor S2 and reading the printed line by the reading sensor S3.

The line editing unit 11 edits the number of transfer steps based on the already-printed line data, and issues a transfer command to the transfer control unit 9.

The transport controller 9 rotates the pulse motor M1 by the commanded number of steps, moves the passbook 1a by driving the feed rollers R1 to R3, and sets printable lines in the printer unit 8a.

Then, when the operator inputs data such as the transaction amount from the keyboard 4, the main control unit 19 communicates with the host,
Receive response data to be recorded.

Therefore, the determination unit 14a searches whether or not the already-printed line data in the line data memory 10 is included in the number of lines set in the one-way printed line table 13a.

If there is no printed line data within the set number of lines, the determination unit 13b notifies the main control unit 19 of the signal a. Then, the signal a is sent from the main control unit 19 to the switching control unit 14a, and the switching control unit 14a instructs the printing control unit 12 to perform normal printing (one of reciprocating printing).

Subsequently, the main control unit 19 sends response data to the print control unit 12, and printing is performed during one of the reciprocating printing.

When the already-printed line data is included in the set number of lines, the determination unit 13b sends a signal b to the main control unit 19. Then, the signal b is sent from the main control unit 19 to the switching control unit 14a, and the switching control unit 14a instructs the print control unit 12 to perform one-way printing.

Subsequently, the main control unit 19 sends response data to the print control unit 12, and one-way printing is performed. That is, printing is performed in the direction from the right end of the passbook 1a toward the guide surface 60a.

When the bookkeeping is completed by the above or the printing of the line, the passbook 1a is sent to the R / W unit 7, the balance and the like are recorded in the magnetic step, and sent out to the insertion slot 2a. When the passbook 1a is returned and the detection of the sensor S1 is released, the row data memory 10 is cleared.

When the data to be printed extends to the next line, the main control unit 19 adds +1 to the line data in the line data memory 10 and stores it in the line data memory 10 again, and then line feed is performed.

Therefore, the subsequent flow is repeated.

In this way, for example, the first to third lines at the tip of the passbook 1a
When the line is a printable line, it is not sandwiched between the feed roller R3 and the press roller R6, so that one-way printing is performed at first, but by printing a plurality of lines, the fourth and subsequent lines are printed. Since the sheet is nipped between the feed roller R3 and the pressing roller R6, reciprocal printing is performed.

In addition, when the line at the rear end of the passbook 1a, for example, the line before line 17 is a printable line, reciprocal printing is performed first, but when it reaches the 18th line by printing multiple lines, the feed roller R2 and the pressing roller are pressed. Since the holding of the roller R5 is released, the printing is switched to the one-way printing.

〔The invention's effect〕

As described above, according to the present invention, when a printable line of a passbook is set at the position of the printing means, if one of the feed rollers arranged before and after the printing means does not hold the passbook, In addition, since one-way printing in the direction of the guide surface of the transport path can be performed, there is an effect that printing deviation for each line due to reciprocal printing can be prevented.
