Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] It is an object of the present invention to prevent the occurrence of defective turning due to double feed or slip when turning pages of a passbook set at a turning point by an automatic page turning mechanism. The second page is pushed back in the early stage of the double feed generation to achieve the purpose.

[Industrial application field]

The present invention relates to an improvement of an automatic page turning mechanism for a passbook.

In a processing device such as an automated teller machine installed at a bank counter or the like, transactions are carried out based on a card or a passbook inserted by a customer. In this case, the passbook inserted from the insertion slot in the opened state often requires a page break when printing the transaction result. At the time of this page break, the passbook is positioned at the turning point, where page turning is performed by the automatic page turning mechanism. This page turning is
It is necessary to perform surely without causing the double feed (double turning) and the turning failure due to slip.

[Conventional technology]

5 and 6 are a front view and a front view showing a conventional automatic page turning mechanism of a passbook, in which 100 is a passbook positioned at a turning point (a) and 1 is an automatic page turning mechanism of the passbook. is there. The automatic page-turning mechanism 1 includes a pair of coaxial turning rollers 2 such as rubber rollers and a pair of coaxial facing rollers 3 such as rubber rollers. Each of these rollers is driven by a drive system (not shown) to rotate in the same direction as indicated by an arrow in FIG. 6, and the counter roller 3 is closed by a solid line which is pressed against the turning roller 2 through the passbook 100. The position (operating position) and the open position (retraction position) of the chain line retracted from the passbook 100 are positioned. Reference numeral 4 is a spring for urging the facing roller 3, and the facing roller 3 in the closed position is given a pressure contact force to the turning roller 2 by the spring 4. Passbook 10 positioned at the turning point (a)
When turning 0 pages, the facing roller 3 is positioned at the closed position indicated by the solid line, and the facing roller 3 and the turning roller 2 are rotated in the directions of the arrows in FIG. As a result, the page of the passbook 100 is turned.

[Problems to be solved by the invention]

In the passbook page turning mechanism having such a configuration and action, double feed occurs when the pressure contact force of the facing roller against the turning roller is large, and when the pressure contact force is small, turning failure due to slip occurs. However, it is difficult to make this adjustment completely, and it is strongly desired to take appropriate external measures.

[Means for solving problems]

The present invention provides an automatic page-turning mechanism for a passbook that can solve the above-mentioned problems, and as a means therefor, in the present invention, a turning roller that rotates in opposition to the passbook positioned at a turning point is provided. , A page of a passbook by an automatic page-turning mechanism provided with an opposing member that is provided so as to face the turning roller and presses against the turning roller via a passbook and can move back and forth between a position retracted from the operating position. In a processing device for turning the page and then sending the passbook to the next processing unit, a double feed preventing roller is provided which engages with the page of the passbook that has been partially turned by the turning roller and rotates in the opposite direction to the turning roller. At the same time, the facing member is retracted from the operating position after the turned-over passbook page is engaged with the double feed prevention roller.

[Action]

At the time of turning the page, the counter member is pressed against the turning roller through a passbook, and the pressing force is made as small as possible within the range where slip does not occur. In this state, the page turning is started, but the facing member is retracted from the passbook after the pages of the passbook which are turned halfway are engaged with the double feed preventing roller. Therefore, even if a double feed occurs when turning the page, the second page is pushed back by the double feed prevention roller. The first page is surely turned in the form of being sandwiched between the turning roller and the double feed preventing roller that rotates in the direction opposite to the turning roller.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 is a plan view showing an automatic page turning mechanism of a passbook according to the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a side view thereof.
11 is an automatic page turning mechanism of the passbook.

The automatic page turning mechanism 11 includes a pair of turning rollers 12 and 13 and turning auxiliary rollers 14, 15 and 16 provided coaxially.
And a pair of opposing rollers (opposing members) 17 and 18 provided coaxially to face the turning rollers 12 and 13, and a pair of double feed preventing rollers 19 and 20 provided coaxially. Each of these rollers is driven by a drive system (not shown) to rotate in the direction of the arrow in FIG.

The auxiliary rollers 14, 15, 16 have an outer diameter (about 2 mm in diameter) slightly larger than the turning rollers 12, 13 and play an auxiliary role of preventing double feed and slip.

Opposing rollers 17 and 18 are turning rollers 12 and 13 through the passbook 100.
The operating position (the position shown by the solid line in FIG. 2) that is pressed against the
It is positioned at the retracted position (the position indicated by the chain line in FIG. 2) retracted from 0. The pressure contact force between the opposing rollers 17 and 18 in the operating position is the spring 21 (see FIG. 2).
Given by.

The double feed preventing rollers 19 and 20 are provided at positions where they are engaged with the pages of the passbook that are partially turned by the turning rollers, and are biased downward by the spring 22 in FIG.

The passbook automatic page turning mechanism 11 is configured as described above,
Next, the operation will be described in relation to the effect.

When turning the page of the passbook 100 set at the turning point, the facing rollers 17 and 18 are positioned at the operating position to start turning the page, but in the case of this example, the turning assist rollers 14, 15 and 16 are provided. Since it has a double feed function and an auxiliary role in preventing slippage, the pressure contact force between the opposed rollers 17 and 18 can be made relatively small. Then, by turning each roller in this state, page turning is started. When the page turning progresses to a certain extent, the double feed prevention roller as shown in FIG.
19 and 20 blind is engaged with the first piece of page 23 ₁ that is being, this page 23 ₁ is held in Yamagata state by turning rollers 12, 13 and double feed prevention roller 19 and 20. here,
The opposed rollers 17 and 18 are positioned at the retracted position. Therefore, even if double-feed occurs when turning pages, the second sheet of page 23 ₂ is pushed back by the double feed prevention roller 19 and 20, double feed is eliminated. In this case, role spring 22 to facilitate the pushing back of the page 23 _3. On the other hand, the first sheet of the page 23 _1, the turning rollers 12 and 13 are turned completely without causing slippage in a sandwich has been shaped by the double feed prevention roller 19, 20 to rotate to the opposite direction.

The passbook that has completed the predetermined page turning is sent to the printing unit, where the transaction contents are printed on the passbook.

〔The invention's effect〕

As described above, according to the present invention, slippage and double feed at the time of turning pages can be prevented.
