Field of the Invention The present invention relates to a page turning device for use in a passbook printer used in a financial institution or the like, which is used when printing of the highest print page of a passbook is completed and printing is performed on the next print page.

[0002]

2. Description of the Related Art FIG. 6 is a front view showing an example of a conventional page turning device of a passbook printer.

In a passbook printer used in a financial institution or the like, a conventional page turning device used when printing of the top print page of a passbook is completed and printing is performed on the next print page is as shown in FIG. , Two transfer rollers 20 and 21 provided in parallel and rotatable in both forward and reverse directions, and tension rollers 27 and 28 provided opposite to the transfer rollers 20 and 21 and holding the passbook 4 therebetween.
And a turning roller 22 provided between the conveying rollers 20 and 21 and rotated by a driving source different from the driving source of the conveying rollers 20 and 21, and provided opposite to the turning roller 22 to pinch the passbook 4 Tension roller 29
A guide 24 for guiding the lower surface of the conveyed passbook 4;
Guides 25 and 2 for guiding the upper surface of conveyed passbook 4
6 and a guide 23 provided above the turning roller 22 for restricting the movement of the printed page turned.

[0004] The page turning device configured as described above operates as follows.

First, the passbook 4 is transported in the direction of arrow J in the figure by the transport roller 20 and the tension roller 27 and the transport roller 21 and the tension roller 28. When the print page to be turned reaches the position of the turning roller 22 and the tension roller 29, the conveyance of the passbook 4 is stopped. At this time, the binding section 4a of the passbook 4
Is perpendicular to the transport direction of the passbook 4. When the turning roller 22 is rotated in the direction of the arrow L in this state, the passbook 4
Is separated from the second and subsequent print pages and lifted in the direction of arrow L. Subsequently, when the turning roller 22 is rotated in the same direction, the leading end of the uppermost print page 4b separates from the turning roller 22 and comes into contact with the guide 23 on the turning roller 22 as shown by reference numeral 4c. Next, when the transport rollers 20 and 21 are reversed to transport the passbook 4 in the direction of the arrow K, the turned-up uppermost print page 4b is reversed and mounted on the opposite print page.

[0006]

In the conventional page turning device of the passbook printer as described above, since the direction of turning up the top print page is perpendicular to the binding portion of the passbook 4, the print page is weak. For this reason, there is a drawback that there is a case where there is a failure to turn or a case where two sheets are turned.

[0007]

According to the present invention, there is provided a page turning device for a passbook printer, comprising two parallel transport rollers which are arranged at right angles to the transport direction of the passbook and are rotatable in both forward and reverse directions.

A supporting bracket and a bearing for supporting, and when the separation roller moves in a direction in which the page turning operation is performed, the separation roller is not rotated and the separation roller is in a retreat direction. When moving are those comprising a one-way clutch to rotate the separation roller,
In particular, an arm for holding a separation roller at the tip, two parallel parallel links of the same length with one end pivotally connected to the center and the end of the arm, and an end of the arm. comprising a first pulley provided on the coupled parallel link section, the linear motion drive mechanism having a motor for driving the movement of the arm via a second pulley and a timing belt which is provided on the rotary shaft Things.

[0008]

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

FIG. 1 is a perspective view showing an embodiment of the present invention,
2 to 5 are perspective views showing different operation states of the embodiment of FIG.

The page turning device of the passbook printer shown in FIG. 1 is provided in parallel with two transport rollers 1 and 2 which are driven to rotate in both forward and reverse directions by a motor (not shown).
And tension rollers 3 and 7 (the tension roller 7 is not shown) which are provided opposite to the transport rollers 1 and 2 to sandwich the passbook 4 and are provided between the transport rollers 1 and 2, respectively. And 2, a one-way clutch 6 for rotating the separation roller 5 only in the direction of arrow A, and a separation roller 5 at the tip end via the one-way clutch 6. An arm 14, and two parallel parallel links 15a and 15b of the same length, one end of which is rotatably connected to the center and the end of the arm 14,
A pulley 16 provided on a parallel link 15b coupled to a distal end of the arm 14, a motor 19 for driving the movement of the arm 14 via a pulley 17 provided on a rotating shaft and a timing belt 18, and a side end face of the bankbook 4 A support bracket 10 and an bearing 11 for supporting the end of the transport roller 1 further inside (the bankbook 4). The arm 14, the parallel link 15a, the parallel link 15b, the pulley 16, the pulley 17, the timing belt 18, and the motor 19 constitute a separation roller moving mechanism.

Next, the operation of the page turning apparatus configured as described above will be described with reference to FIGS.

First, as shown in FIG.
Are rotated in the direction of arrow B, and the passbook 4 is conveyed in the direction of arrow C. When the rear end of the passbook 4 has passed the conveying roller 1, the conveying rollers 1 and 2 are stopped. In this case, the separation roller 5 is retracted to a position outside the side end surface of the passbook 4 by operating the separation roller moving mechanism.

[0013] Next, as shown in FIG. 3, the motor 19 is operated to drive the parallel link 15a and the parallel link 15b via a pulley 16 and a pulley 17 and a timing belt 18, the operation arm 14 in the direction of arrow D Let
Thereby , the separation roller 5 is moved to a position inside the side end surface of the book 4. At this time, since the separation roller 5 is prevented from rotating by the action of the one-way clutch 6,
It moves in contact with the top printed page of the passbook 4, moves while pressing the corner of the top printed page of the passbook 4, and lifts the end of the top printed page of the passbook 4 to two sheets. An interpage space 30 is formed between the page and the printed page of the eye. At this time, since the separation roller 5 moves in parallel with the binding portion 4a of the passbook 4, the top printed page of the passbook 4 gradually becomes stiffer as the separation progresses, and the second printed page is surely formed. Becomes larger than the friction force. Therefore, it is difficult to separate
The sheets are not separated, but only one is surely separated.

Next, as shown in FIG. 4, the transport rollers 1 and 2 are rotated in the direction of arrow E to transport the passbook 4 in the direction of arrow F, and at the same time, the motor 19 is operated to operate the arm 14.
And the separation roller 5 is retracted in the direction of arrow G. At this time, a support bracket 10 for supporting the end of the transport roller 1
Since the bearing 11 and the bearing 11 are arranged on the inner side of the side end face of the bankbook 4 (toward the bankbook 4) and located at a position corresponding to the inter-page space 30 (see FIG. 3), the transport roller 1, the support bracket 10, and the bearing 11 is inserted without difficulty between the uppermost printed page and the second printed page. When the separation roller 5 is retracted in the direction of arrow G, it rotates smoothly by the action of the one-way clutch 6 and has no effect on the uppermost printed page separated.

Next, as shown in FIG. 5, the transport rollers 1 and 2 are continuously rotated in the direction of arrow E, and the passbook 4 is moved in the direction of arrow F.
When the sheet is conveyed in the direction, the uppermost printed page that has been separated is turned over and placed on the opposite printed page, and the page turning operation is completed.

In the above embodiment, the separation roller 5
Although a motor and a parallel link mechanism for converting the rotational motion of the motor into a linear motion are employed as a mechanism for driving the linear motion, a linear motion drive mechanism using a solenoid or a ball screw may also be employed.

[0017]

As described above, the page turning device of the passbook printer according to the present invention comprises two parallel transport rollers which are arranged at right angles to the transport direction of the passbook and are rotatable in both forward and reverse directions. In a normal state, a separation roller which is outside the passbook transport path and moves in a direction perpendicular to the passbook transport direction while contacting the top printed page of the passbook to be turned when performing a page turning operation. And a linear motion drive mechanism for driving the linear motion of the separation roller, wherein the end of the transport roller on the print page side of the two transport rollers on which a page is to be turned is located inside the side edge of the passbook. When the separation roller moves in the direction in which the page turning operation is performed, the separation roller does not rotate, and when the separation roller moves in the retreat direction, the separation roller rotates. By the action of Ikuratchi, without or perform turning two or a missed turn, there is an effect that it is possible to reliably perform only one page turning.
