Abstract

PURPOSE:To prevent printing from shear by removing a bulge to be generated in internal paper of an open passbook. CONSTITUTION:A control means 107 carries a passbook to a position wherein a platen is opposed to near a center hold part of internal paper in which a printing start line recognized by a printing start line recognizing means 106 exists. A pressure roller 45b or 46b being in pressure contact with the internal paper in which the printing start line exists is released by a releasing means. The passbook is moved by driving a stepping motor 31 until a detecting means 100 detects that a carriage 42 comes in contact with the passbook. Then, the pressure roller 45b or 46b being in a released state is again brought into pressure contact with the passbook.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a passbook printing device for a passbook processing device used in financial institutions.

0002

[Prior Art] Conventionally, this type of device was
0673, FIG. 6 is a side sectional view showing the overall configuration of the passbook processing device, and FIG. 7 is a side view of the main part of FIG. 6. The passbook processing device shown in FIG. 6 does not require operator intervention. It has a function to automatically issue a new passbook.

[0003] 1 is a new passbook storage part that stores a newly issued passbook 2 in a folded state, and 3 is a passbook 2.
A passbook insertion/ejection port 4 is used to insert and eject the passbook 2, and 4 is a printing unit that performs printing processing on the passbook 2 by a print head 5.

[0004] FIG. 8 is an explanatory diagram of the passbook 2. As mentioned above, 2 is a passbook, and includes a front cover 2a on which the customer's name, account number, etc. are printed, and a back cover 2b that is paired with the front cover 2a.
, transaction details, etc. are printed, and can be opened and closed using the center hold 2d as a fold. 2e is a page code in which information such as pages is incorporated, and 2f is a magnetic stripe in which various information such as customer information and transaction information is magnetically recorded. The printing lines in this passbook 2 are divided into 1st to 12th lines and 13th to 24th lines on the inner paper 2c with the center hold 2d as a boundary.

Returning to FIG. 6, reference numeral 6 denotes a magnetic read/write unit for magnetically writing information on the magnetic stripe 2f of the passbook 2 with a magnetic head 6a, or magnetically reading information on the magnetic stripe 2f, and 8 a page turning roller. 9 is a page break section for turning the pages of the bankbook 2; 10 is a conveyance path connecting the above parts; 15 is a conveyance path 10 that pinches the bankbook 2 from above and below, and conveys the bankbook 2 along the conveyance path 10 by pressing and rotating it; The conveyance roller system 7 is a main control section that controls the operation of each section mentioned above.

As mentioned above, FIG. 7 is a side view of the main part of FIG. 6, showing the conveyance system in the printing section 4. As shown in FIG. 15a, 15
Reference numeral b denotes a conveyance roller that conveys the bankbook between the page break section 8 and the printing section 4, and 16 denotes a stepping roller that rotationally drives the conveyance roller 15a on the side that comes into contact with the inner paper 2c side when the bankbook 2 is open, via a belt 17. The motor 18 is a conveyance roller 15 on the side that comes into contact with the cover 2a side (back cover 2b side) when the passbook 2 is open.
A stepping motor 20, 21 is a motor control section that controls the rotational drive and conveyance amount (rotation amount) of the stepping motors 16, 18, and the main control section 7 shown in FIG. Control is performed according to instructions. 22 is the passbook 2 for transporting the passbook 2 to a predetermined position.
This is a sensor that detects the upper and lower end surfaces of the passbook 2, and it grasps the position of the passbook 2 and uses it as a trigger for various control switching.

With the above configuration, when the bankbook 2 is inserted through the bankbook insertion/ejection port 3, the magnetic reading/writing unit 6 reads information from the magnetic stripe 2f of the inserted bankbook 2 and sends the information to a center computer (not shown). , receives unrecorded data etc. from the center computer, and prints it to the printing unit 4.
The printing process is performed by In addition, if unrecorded data remains even after all lines of the opened page have been printed, the page break section 8 performs a page break on the inner paper of the passbook 2, and the printing section 4 performs the printing process. When the printing process is completed, the magnetic reading/writing section 6 updates the information on the magnetic stripe 2f of the passbook 2, and the passbook is ejected from the passbook insertion/ejection port 3.

[0008] During the printing process described above, if the printable pages of the passbook 2 run out and the passbook is carried over, or if a new passbook issue command is received, one passbook 2 is taken out from the new passbook storage section 1 and printed. It is transported to section 4, where the account number, name, store number, etc. are printed on the cover 2a, and then transported to page break section 8, where page breaks are made (cover page is turned).
After that, it is transported again to the printing section 4, where unrecorded data is printed on the inner paper 2c, and transported to the magnetic reading/writing section 6, where information is written on the magnetic stripe 2f, and the passbook insertion/ejection port 3 is then transported to the printing section 4.
Then, the process is completed.

[0009]Here, to explain the transportation operation after a new page change (cover turning) of a new bankbook, which is the gist of the technology disclosed in JP-A No. 63-120673, the new bankbook 2 for issuance is closed. Because it is stored in the new passbook storage section 1 in this state, the folds are particularly strong, and when the page break section 8 performs a page break operation after performing the prescribed printing process on the cover 2a, the center page is folded as shown in Figure 9. A bulge occurs in the paper 2c, and the inner paper 2c of the passbook 2 deviates by ΔL from the cover 2a by the bulge.

In order to remove this bulge, when the newly issued passbook 2 with the cover printed is conveyed to the printing section 4 again after a page break operation is performed in the page break section 8, the sensor 22
The transport rollers 15a and 1
5b are rotated by the stepping motors 16 and 18 controlled by the motor control units 20 and 21, respectively, so as to achieve the same conveyance amount. Then, when the control section 7 recognizes that the sensor 22 has detected the leading end of the bankbook 2, the motor control section 20 receives this and increases the amount of transport by the transport rollers 15a for a certain period of time than the amount of transport by the transport rollers 15b. As a result, the inner paper 2c is conveyed slightly more than the cover 2a, thereby eliminating the shift ΔL on the inner paper 2c side and preventing the printing position from shifting due to the shift of the inner paper 2c. Note that depending on the position of the center hold 2d and the conveyance direction of the passbook 2, it is determined whether the conveyance amount of the conveyance roller 15a is increased or decreased relative to the conveyance roller 15b. Needless to say, the conveyance amount must be controlled to a large extent when doing so.

[0011]

However, the conventional passbook printing device described above has the following problems. In other words, the amount of bulge in the inner paper that occurs when the inner paper is opened due to page breaks varies greatly depending on the number of inner paper sheets, paper thickness, and number of page breaks, and the amount of deviation of the inner paper from the cover is also not constant. It is difficult to control the conveyance amount by the conveyance rollers to change the amount of conveyance by the conveyance rollers in accordance with the amount of displacement.The difference in the conveyance amount is set to be constant regardless of the amount of deviation. However, if the difference in transport amount is set to a small value and the difference in transport amount is set to a small value, the amount of deviation cannot be absorbed within a certain period of time if the difference in transport amount is large. Even though the amount of misalignment has been absorbed, the amount of transport by the transport roller that contacts the inner paper remains large, causing a slip condition between the inner paper and the transport roller, resulting in dirt (slip marks) at the same position. There is a problem that this occurs, resulting in a decrease in quality.

Furthermore, in order to change the amount of transport between the transport rollers, a plurality of stepping motors are required to drive the transport rollers, which increases the cost of components including drive circuits, etc., and also increases the size of the device. There is also the problem of doing so.

Furthermore, since the inner paper is stretched by applying force in the direction of conveyance, which is a direction horizontal to the surface of the passbook, the bulge in the inner paper is removed and the amount of deviation is absorbed. Also, depending on the friction coefficient of the paper inside the passbook, the passbook itself may move when the paper inside the passbook is stretched out, resulting in changes in the coefficient of friction (for example, adhesion of paper dust, transfer of ink), and the printing process of the cover of the passbook. Considering the type of passbook and the presence of a magnetic stripe surface, it is extremely difficult to set the surface material and pressure of the conveyance roller.

[0014] In addition, in the case of a distributed passbook that has already been issued, the amount of bulge in the inner paper is small even if a page change is performed, so the amount of transport between the transport rollers is adjusted to correspond to the bulge of the inner paper in a newly issued passbook. If the device is set to have a large difference between Then,
There is a problem that there are multiple control methods and the control becomes complicated.

[0015] The present invention solves the above-mentioned problems of difficulty in reliably removing misalignment of inner paper, complicated control for removing misalignment of inner paper, increased cost of materials, and enlargement of the device. The purpose of this invention is to provide a passbook printing device that removes bulges in the inside paper of a passbook without changing the amount of transport by the transport rollers and eliminates printing misalignment.

[0016]

[Means for Solving the Problems] In order to achieve this object, the present invention includes a print head that prints on a passbook, a carriage that supports the print head and moves in a direction perpendicular to the surface of the passbook, and a carriage that supports the print head and moves in a direction perpendicular to the plane of the passbook. The apparatus comprises a carriage driving means for moving, a detection means for detecting that the carriage has contacted the passbook, and a platen provided facing the carriage and the print head, and after detecting that the carriage has contacted the passbook, The passbook printing device has a print head gap adjustment mechanism that moves the carriage a small amount in a direction away from the passbook to create a print head gap between the print head and the passbook, and the passbook printing device has a print head gap adjustment mechanism that moves the carriage a small amount in a direction away from the passbook. first and second conveying means, which are provided and convey the passbook in pressure contact with the passbook by receiving power from the driving means, and are independently released from the pressure contact state with respect to the passbook by a release means; A print start line recognition means for recognizing a print start line, and a conveyance means that transports the passbook to a position where the platen faces the vicinity of the fold side of the page where the print start line exists, and is in pressure contact with the page where the print start line exists. The present invention is characterized in that it is provided with a control means for releasing the page, moving the carriage to bring it into contact with the page, and shifting the conveyance means to the pressure contact state again.

[0017]

[Operation] In the present invention having the above-described configuration, when printing on a passbook, the printing start line is recognized by the printing start line recognizing means. Based on this recognition result, the bankbook is transported to a position where the platen faces the vicinity of the fold side of the page where the print start line exists. When the passbook is conveyed to a predetermined position, the first or second conveying means that is in pressure contact with the page where the printing start line exists is released, and the carriage is moved to come into contact with the page. When it is detected that the carriage has come into contact with the passbook, the movement of the carriage is stopped, and the first or second conveying means, which had been released from the press-contact state with respect to the passbook, is again brought into the press-contact state. Thereafter, the carriage is moved in a direction away from the passbook, and the first and second transport means transport the passbook to a position where the print head faces the recognized printing start line, and the carriage is moved to connect the print head and the passbook. Printing is performed by forming an optimal print head gap between the two.

Then, the bankbook 2 is conveyed by rotating the feed roller 46a while holding the bankbook 2 while the pressure roller 46b is moved in a direction to press against the feed roller 46a.

The control system of this embodiment will be explained below using FIG. As mentioned above, 42 is a carriage, and 31 is a stepping motor that is a driving means for the carriage. Reference numeral 100 denotes a detection means for detecting that the carriage 42 has come into contact with the passbook 2, and here it is composed of the slit disk 37 and the slit detection element 38, which detect the rotation of the stepping motor 31, as explained in FIG. .

is a control means for controlling each of the above-mentioned parts to remove the bulge in the inner paper of the passbook.

A method of adjusting the print head gap in the print section 4 shown in FIG. 2 will now be described. At this time, it is assumed that the bankbook 2 has already been conveyed onto the platen 13 to the position where printing is to be performed. When the stepping motor 31 is rotated clockwise, the motor gear 32 and the idle gears 33a, 3
3b, the rotation is further transmitted to driven gears 35a, 35b, and a cam 36 coaxial with driven gears 35a, 35b
a, the cam 36b rotates, and the main shaft 39 is pushed down against the tension of the coil spring 44. That is, the carriage 42 starts descending toward the platen 13. When the stepping motor 31 continues to rotate,
The carriage 42 and the passbook 2 come into contact, and then the platen 13
be forced to. In this state, stepping motor 3
Even if the motor 1 attempts to rotate, the carriage 42 cannot descend, and the rotation of the stepping motor 31 is forcibly stopped.

Here, the slit of the slit disk 37 disposed coaxially with the cam 36a generates an ON/OFF signal by the detection element 38 as it rotates, and controls the rotation of the stepping motor 31 from the start of rotation to a forced stop. The amount of movement is detected. The stepping motor 31 is out of step after the carriage 42 contacts the passbook 2, and even if a rotation command is given to the stepping motor 31 for a predetermined number of steps, if an ON/OFF signal is not generated from the slit detection element 38, a clockwise rotation command is issued. Terminate it. Then, when a predetermined number of steps is selected and the stepping motor 31 is rotated counterclockwise so as to obtain the optimum print head gap, the carriage 42 rises by a minute amount and the print head 5
The optimal print head gap is set between and passbook 2,
The printer is ready to print.

Thereafter, the carriage 42 is moved in the direction of the printing digits using a spacing means (not shown) to execute the printing process. When the printing process is completed, the stepping motor 31 is given a counterclockwise rotation command again, and the carriage 42 moves toward the passbook 2. It rises in the direction further away and returns to the origin position.

Next, a method for removing the bulge in the inner paper in this embodiment will be explained. FIG. 4 is a flowchart in this embodiment, and FIG. 5 is an explanatory diagram showing the mechanical action in this embodiment. Note that, in addition to issuing a new passbook from the new passbook storage section 1, the case of an already issued circulating passbook inserted from the passbook insertion/ejection port 3 will also be described as removing the bulge in the inner paper.

A part of the newly issued passbook 2 is taken out from the new passbook storage part 1, and after the predetermined printing process is performed on the cover 2a in the printing part 4, it is returned to the page break part 8, a page break operation is performed, and then the page break is performed again. Either transport the issued passbook 2 to the printing section 4 or insert it through the passbook insertion/ejection port 3 by opening a predetermined page, read the information from the magnetic stripe 2f with the magnetic head 6a, and insert the passbook into the printing section 4. When conveying (S1), the control means 107
recognizes the print start line via the print start line recognition means 106. In the case of a newly issued passbook 2, the printing start position is basically the first line, and in the case of an already issued circulation passbook 2, the printed line is detected by an optical sensor, or the previous line is marked on the magnetic stripe. There is a method of storing the information of the printed lines up to the present time and reading and recognizing the information (S2).

In S2, the printing start line is 1 of the inner paper 2c.
~If it is determined that it is located at the 12th line, 1~ of the inner paper 2c
Near the center hold 2d on the 12th row side, here the 10th row two rows before the center hold 2d and the platen 13
Then, the feed rollers 45a and 46a are driven by the stepping motor 105 to convey the passbook 2 to a position where the print head 5 faces. At this time, the release means 102, 104
The pressure rollers 45b and 46b are both moved in the direction in which they come into pressure contact with the feed rollers 45a and 46a to grip and convey the bankbook 2, and a sensor (not shown) measures the amount of conveyance.
This can be controlled by counting the number of steps of the stepping motor 105 after detecting the tip of the S
3).

When the passbook 2 is conveyed to a predetermined position, the stepping motor 105 moves the feed roller 45a,
46a is stopped to stop the passbook 2. and,
The pressure roller shaft 46e is released by the release means 104.
is rotated by a certain angle, the pressure roller 46b is moved in a direction away from the feed roller 46a, and the state of pressure contact with the inner paper 2c on which printing of the passbook 2 is to be performed is released (S
4). This state is shown in FIG. 5(a).

Next, the control means 107 controls the stepping motor 3 in the same way as in the print head gap adjustment method described above.
1 is rotated clockwise, and the carriage 42 starts descending toward the platen 13 (S5). When the stepping motor 31 continues to rotate further, the carriage 42 and the passbook 2 come into contact with each other and are in pressure contact. In this state, the bulge of the inner paper 2c to be printed is crushed by the carriage 42,
It is extended toward the pressure roller 46b side. At this time, since the pressure roller 46b is no longer in pressure contact with the inner paper 2c, the above action is not hindered.

Even if the stepping motor 31 attempts to rotate further from the state in which the carriage 42 is in pressure contact with the inner paper 2c, the carriage 42 cannot descend, and the rotation of the stepping motor 31 is forcibly stopped. Therefore, regardless of the amount of bulge in the inner paper 2c, the bulge is reliably removed, and at this time, the passbook 2 has a
In other words, force is applied in a direction perpendicular to the transport direction, and no force is applied to the passbook 2 in the transport direction.

The stepping motor 31 is connected to the carriage 42
After contacting the passbook 2, the stepping motor 31 loses synchronization, and even if a rotation command is given to the stepping motor 31 for a predetermined number of steps, if an ON/OFF signal is not generated from the slit detection element 38, the clockwise rotation command is terminated.

Furthermore, the pressure roller shaft 46e
is rotated by a certain angle in the opposite direction to the above, and the pressure roller 46b is brought into pressure contact with the inner paper 2c. This results in
The passbook 2 has a feed roller 45a and a pressure roller 45.
b, feed roller 46a and pressure roller 46b
Because of this, the inner paper 2c is held without any bulge (
S6). This state is shown in FIG. 5(b).

Next, the stepping motor 31 is rotated counterclockwise to raise the carriage 42 to the origin. At this time, the number of steps of the stepping motor 31 when the carriage 42 is moved from the state in contact with the inner paper 2c of the bankbook 2 to the origin is counted (S7). Feed roller 45
a, 46a to transport the passbook 2 to a position where the print head 5 and the print start line face each other, and the stepping motor counted when the carriage 42 was moved from the state in contact with the inner paper 2c of the passbook 2 to the origin. Based on the number of steps 31, the number of steps required to move the carriage to the position where the optimum print head gap is obtained between the print head 5 and the inner paper 2c is determined, and the stepping motor 31 is activated by the number of steps. Rotate clockwise to obtain the optimal print head gap and start printing.

Note that if the printing start line is at the position where the carriage 42 compresses the bulge of the inner paper, here the 10th line, the carriage 42 is not returned to the origin,
As shown in the print head gap adjustment method, by raising the carriage by a predetermined amount, printing becomes possible immediately, and processing time can be shortened.

[0042] In the above S2, the printing start line is on the inner paper 2c.
If it is determined that it is located in the 13th to 24th line of
The feed rollers 45a and 46a are driven by the stepping motor 105 to a position where the platen 13 and the print head 5 face the vicinity of the center hold 2d on the 13th to 24th lines, here the 15th line two lines after the center hold 2d. and transport the passbook 2. At this time, the release means 102,
Reference numeral 104 indicates that the pressure rollers 45b and 46b are both moved in the direction of pressure contact with the feed rollers 45a and 46a to grip and convey the bankbook 2, and the amount of conveyance is determined by a stepping motor after a sensor (not shown) detects the tip of the bankbook 2. 10
Control is possible by counting the number of steps of 5 (S8).

When the bankbook 2 is conveyed to a predetermined position, the stepping motor 105 moves the feed roller 45a,
46a is stopped to stop the passbook 2. and,
The pressure roller shaft 45e is released by the release means 102.
is rotated by a certain angle, and the pressure roller 45b is moved in a direction away from the feed roller 45a to release the pressed state with the inner paper 2c on which printing of the passbook 2 is to be performed (S
9). This state is shown in FIG. 5(c).

Next, the control means 107 controls the stepping motor 3 in the same manner as in the print head gap adjustment method described above.
1 is rotated clockwise, and the carriage 42 starts descending toward the platen 13 (S10).

When the stepping motor 31 continues to rotate further, the carriage 42 and the passbook 2 come into contact with each other and are in pressure contact. In this state, the bulge of the inner paper 2c on which printing is to be performed is crushed by the carriage 42 and stretched toward the pressure roller 45b. At this time, since the pressure roller 45b is no longer in pressure contact with the inner paper 2c, the above action is not hindered. Carriage 4
Even if the stepping motor 31 attempts to rotate further from the state in which the inner paper 2c is in pressure contact with the inner paper 2c, the carriage 42 cannot be lowered, and the rotation of the stepping motor 31 is forcibly stopped. Therefore, regardless of the amount of bulge in the inner paper 2c, the bulge is reliably removed, and at this time,
A force is applied to the passbook 2 in a direction parallel to the plane of the passbook, that is, in a direction perpendicular to the transport direction, and no force is applied to the passbook 2 in the transport direction.

The stepping motor 31 is connected to the carriage 42
After contacting the passbook 2, the stepping motor 31 loses synchronization, and even if a rotation command is given to the stepping motor 31 for a predetermined number of steps, if an ON/OFF signal is not generated from the slit detection element 38, the clockwise rotation command is terminated. Furthermore, the pressure roller shaft 45e is rotated by a certain angle in the opposite direction to the above, and the pressure roller 45b is brought into pressure contact with the inner paper 2c. As a result, the passbook 2 is held between the feed roller 45a, the pressure roller 45b, and the feed roller 46a and the pressure roller 46b with the inner paper 2c having no bulge (S11).

Next, the stepping motor 31 is rotated counterclockwise to raise the carriage 42 to the origin. At this time, the number of steps of the stepping motor 31 when the carriage 42 is moved from the state in contact with the inner paper 2c of the bankbook 2 to the origin is counted (S7). Feed roller 45
a, 46a to transport the passbook 2 to a position where the print head 5 and the print start line face each other, and the stepping motor counted when the carriage 42 was moved from the state in contact with the inner paper 2c of the passbook 2 to the origin. Based on the number of steps 31, the number of steps required to move the carriage to the position where the optimum print head gap is obtained between the print head 5 and the inner paper 2c is determined, and the stepping motor 31 is activated by the number of steps. Rotate clockwise to obtain the optimal print head gap and start printing.

Note that when the printing start line is at the position where the carriage 42 compresses the bulge of the inner paper, here the 15th line, the carriage 42 is not returned to the origin,
As shown in the print head gap adjustment method, by raising the carriage by a predetermined amount, printing becomes possible immediately, and processing time can be shortened.

[0049] In this embodiment, the bulge in the inner paper is also removed for issued circulation passbooks, but even if the printing start position and the page to be pressed to remove the bulge in the inner paper are the same. For example, as mentioned above, the position where the optimal gap for printing can be immediately obtained between the print head and the passbook from the origin without having to go through the entire process of adjusting the print head gap again after removing the bulge in the inner paper. The carriage can be lowered up to a maximum of 100 degrees, and the effect on the overall processing speed is almost negligible. In this way, this embodiment uses the existing print head gap adjustment mechanism provided in the passbook printing device, so there is almost no increase in material costs and there is no need to perform complicated controls to suit individual conditions. .

[0050]

As explained above, the present invention provides a print head that prints on a bankbook, a carriage that supports the print head and moves in a direction perpendicular to the surface of the bankbook, and a carriage drive means that moves the carriage. , a detection means for detecting that the carriage has come into contact with the passbook, and a platen provided facing the carriage and the print head, and after detecting that the carriage has come into contact with the passbook, the carriage is removed from the passbook. This passbook printing device has a print head gap adjustment mechanism that moves the print head a small amount in the direction away from the passbook to create a print head gap between the print head and the passbook. The first and second conveying means transport the passbook in a pressure-contact state by receiving power from the drive means, and the release unit independently releases the pressure-contact state with respect to the passbook, and recognizes the print start line of the passbook. conveying the passbook to a position where the print start line recognition means and the platen face the vicinity of the fold side of the page where the print start line exists, and releasing the conveyance means that is in pressure contact with the page where the print start line exists, A control means is provided for moving the carriage so as to bring it into contact with the page and again shifting the conveying means to the press-contact state.

[0051] Therefore, we decided to apply force in the direction perpendicular to the plane of the passbook using the carriage to crush the inner paper on which printing will be performed near the crease, thereby removing the bulge in the inner paper and absorbing the shift of the inner paper against the cover. This can prevent misalignment of the printing position. At this time, the amount that the carriage moves is until the carriage presses the passbook against the platen, but it is easy to recognize this, and even if the amount of bulge in the inner paper changes, it can be firmly crushed. Can be done.

Furthermore, since no force is applied in the direction horizontal to the transport surface of the passbook, that is, in the transport direction, the entire passbook may move when trying to correct misalignment, or the passbook that cannot be moved may be moved in the transport direction. By applying force to the paper, you won't stain your bankbook. In this way, since the displacement of the inner paper can be reliably absorbed, the position of the page code recorded on the inner paper is also accurately positioned with respect to the reading means, and reading errors are reduced.
