Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of driving a page-turning device of a printer which inserts a passbook and turns a printed page while performing printing.

[0002]

2. Description of the Related Art FIG. 3 is a front view showing an example of a page turning device of a conventional passbook printer, and FIG. 4 is a front view showing an operating state of the page turning device of FIG.

As shown in FIG. 3, a conventional page-turning device for a passbook printer is provided between two pairs of transport rollers 1 and 2 for sandwiching and transporting a passbook, and between these two pairs of transport rollers 1 and 2. Page turning roller 3 and page turning roller 3
Between the press roller 4 which is pressed from below to the lower paper guide 7 which is provided between the respective lower transport rollers of the two pairs of transport rollers 1 and 2, and between the press roller 4 and the transport roller 1. It is provided with a push-up bar 5 which passes through the lower paper guide 7 to push up and bend the passbook, and an upper paper guide 6 provided above the page-turning roller 3 between the transport rollers 1 and 2. .

The page-turning device thus constructed operates as follows. That is, as shown in FIG. 4, the passbook 8 inserted and conveyed from the left side of the figure is conveyed to the page turning position by the conveying roller 1 and stopped. In this state, the press roller 4 is raised to press the printed page of the passbook 8 against the page-turning roller 3, and the page-turning roller 3 is rotated in the direction opposite to the direction in which the passbook is conveyed. As a result, the highest printed page 9 of the passbook 8 is separated from the second and subsequent printed pages. At this time, in order to facilitate the separation of the uppermost printed page 9, the push-up bar 5 is raised and the passbook 8 is pushed up to be curved. Subsequently, the press roller 4 is lowered and the page-turning roller 3 is further rotated in the direction opposite to the direction in which the passbook is conveyed, whereby the separated highest printed page 9 is flipped up onto the page-turning roller 3. When the flip-up of the print page 9 is completed, the transport roller 1 is operated to move the passbook 8 to the transport roller 2.
Is conveyed to the next position and is conveyed to the next step by the conveyance roller 2 to complete the page turning operation.

[0005]

The conventional page-turning device for the passbook printer as described above, when the page-turning operation is performed,
Since the passbook is continuously conveyed after the printed pages have been flipped up, there is a problem that the separated topmost printed page may be caught in the page-turning roller and broken. are doing.

[0006]

According to the method of driving a page-turning device of a passbook printer of the present invention, a passbook is nipped and conveyed.
A method of driving a page-turning device of a passbook printer having a pair of feed rollers and a page-turning mechanism provided between the pair of feed rollers, wherein the printed page of the passbook is flipped up by the page-turning mechanism. When the passbook is conveyed after the operation is completed, when the center of the passbook reaches the position of the page-turning roller of the page-turning mechanism unit, the conveyance of the passbook is temporarily stopped, and then the conveying roller is operated again. And driving to pass the passbook.

That is, the method of driving the page-turning device of the passbook printer according to the present invention includes two pairs of feed rollers for holding the passbook, and a page-turning roller provided between the two pairs of feed rollers. A lower paper guide provided between the press roller that contacts and presses the page-turning roller from below, and the lower pair of transport rollers of each of the two pairs of transport rollers, and the lower roller guide and the press roller and the pair of transport rollers. Above the page-turning roller between the pair of conveying rollers and the push-up bar that passes through the lower paper guide and pushes up and bends the passbook. A method of driving a page-turning device of a passbook printer, comprising: a page-turning mechanism section having an upper paper guide provided, wherein the operation of flipping up a printed page of the passbook is completed. When conveying the passbook, the center of the passbook contains that causes the transport operation again once stops the conveying operation of the passbook when it reaches to the position of the page turning roller.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a flow chart showing an embodiment of the present invention, and FIG. 2 is a front view showing an operation mode of a page turning device of a passbook printer operating according to the embodiment of FIG.

As shown in FIG. 2 (a), the passbook 8 inserted and conveyed from the left side of the figure is turned by the feeding roller 1 at the page turning position, that is, the print page on the right side of the passbook 8 is turned by the page turning roller 3. The sheet is conveyed to a position that has reached the lower position and stopped (step 51 in FIG. 1). Then, Fig. 2
As shown in (b), the push-up bar 5 is raised to push up the passbook 8 to bend it, and then the press roller 4 is raised to push the printed page of the passbook 8 against the page-turning roller 3 (step 52). . Next, as shown in FIG. 2C, the page turning roller 3 is rotated in the direction opposite to the direction in which the passbook 8 is conveyed (arrow A), and the uppermost printed page 9 on the right side of the passbook 8 is the second sheet. The following printed pages are separated (step 53). Then, Fig. 2
As shown in (d), the push-up bar 5 and the press roller 4
Is lowered (step 54), the page turning roller 3 is further rotated in the direction of arrow A, and the separated topmost printed page 9 is flipped up on the page turning roller 3 (step 55). When the flipping up of the printed page 9 is completed, the carry roller 1 is operated to carry the passbook 8 to the position of the carry roller 2. At this time, when the center of the passbook 8 reaches the position of the page turning roller 3, 8 is once stopped (step 5)
6). After the conveyance of the passbook 8 is temporarily stopped, as shown in FIG. 2E, the conveyance roller 1 is operated again to convey the passbook 8 to the conveyance roller 2, and the conveyance roller 2 continues to convey the page to the next step. Complete the turning motion (Step 5)
7). In this way, when the passbook 8 is conveyed after the flipping of the printed page 9 is finished, when the center of the passbook 8 reaches the position of the page-turning roller 3, the conveyance of the passbook 8 is temporarily stopped and then conveyed again. By driving so that the flipped-up printed page 9 stands still on the page-turning roller 3, the printed page 9 is prevented from being caught by the page-turning roller 3.

[0011]

As described above, according to the method of driving the page-turning device of the passbook printer of the present invention, when the passbook is conveyed after the flip-up operation of the printed page is completed, the center of the passbook is the page-turning roller. When the position is reached, the passbook is stopped from being conveyed and then it is conveyed again.
Since the flipped-up printed page stands still on the page-turning roller, it is possible to prevent the printed page from being caught by the page-turning roller and broken.
