To do.

[Industrial application field]

The present invention relates to a page turning mechanism of a passbook printer used in a financial institution or the like, and more particularly to a page turning mechanism capable of detecting a double field in page turning.

Recently, as a part of a computer banking system, an automatic transaction device such as a cash dispenser (hereinafter referred to as CD), an automatic teller machine (hereinafter referred to as ATM), and a bookkeeping operated by a teller at a counter. Machine is widely used.

Of these devices, those having a page turning function in the passbook printing mechanism are often used to simplify the operation of the customer or the teller. Is desired.

[Conventional technology]

The conventional method will be described below with reference to FIGS. The same reference numerals denote the same objects throughout the drawings.

As shown in FIG. 5, the bookkeeping machine has a device body 2 having an insertion slot 1 into which a passbook 5a is horizontally inserted, a keyboard 3 for operationally inputting a customer's account number, transaction details, etc. It is composed of a display 4 for displaying contents and the like. The device body 2 is connected to a computer sensor (not shown) by a line.

FIG. 6 is an internal side view of the passbook mechanism. In FIG.
Is a conveyance path, 7 is a printer section, and 8 is a page turning section.

Therefore, when the teller inserts the passbook 5a through the insertion slot 1, the passbook 5a is conveyed through the conveyance path 6 by the rollers R ₁ and R ₂ and is sent to the printer unit 7. When the keyboard 3 is operated and input, it is displayed on the display 4. When this is confirmed and the confirmation button is pressed, communication with the computer sensor is performed and the printer unit 7 prints transaction data on the passbook 5a.

If the transaction data is printed over multiple lines and the last line of the page is printed in the middle of printing, the passbook 5a is sent to the page turning unit 8 and page turning is performed, and the printer unit 7 prints again. Is continued. After printing, passbook 5a has 1 slot
Is discharged to.

Next, the details of page turning will be described. The page turning section 8 has rollers 81a and 82a for holding the passbook 5a on the conveying path 6 from above and below.
And a spring 84 rotatably wound around the shaft 83 of the roller 81a and provided with an engagement lever 85a and a flip-up detection lever 86a.
a, a plunger magnet 9 for retracting the roller 82a from the conveyance path 6 and a lever 10, and a shield plate 86b at the tip of the flip-up detection lever 86a normally shields the optical sensor 88a. The rollers 81a and 82a are connected to the motors M ₁ and M ₂ , respectively.

First, when the passbook 5a is sent to the position shown in FIG. 7 (a), the rollers 81a and 82a rotate in the arrow directions (the respective rotation directions in this case are defined as positive directions) and move in the arrow A direction. passbook
5a is transferred, and the rollers 81a and 82a stop at the turning position while holding the passbook 5a.

Next, when the roller 81a is rotated in the forward direction and the roller 82a is rotated in the reverse direction, the page of the passbook 5a is loosened and curved due to friction with the roller 81a, as shown in FIG. 7 (b). The engagement lever 85a is pressed against the surface of the spring, the spring 84 rotates in the forward direction, and the flip-up detection lever 86a also rotates in the same direction to release the shielding of the optical sensor 88a. By this cancellation, the progress of page turning is detected.

When the rollers 81a and 82a further rotate, the curved end portion of the page is flipped up above the roller 81a as shown in FIG. 7 (c). Then, the engagement between the page and the engagement lever 85a is released, and the spring 84a is released from the flip-up detection lever 86a.
And the weight of the shielding plate 86b causes it to rotate in the opposite direction to return to the original position, and the shielding plate 86b again shields the optical sensor 88a to detect the flip-up of the page.

Therefore, as shown in FIG. 7 (d), the roller 82a is retracted by the excitation of the plunger magnet 9 and the roller 81a is retracted.
If a double feed page indicated by a chain double-dashed line is returned by rotating a in the opposite direction, and then returning it, as shown in FIG. 7 (e), the roller 82a is closed by deenergizing the plunger magnet 9. Then, the rollers 81a, 82a are rotated in the opposite direction and the passbook 5a is sent in the direction of the printer unit 7, that is, in the direction of arrow B. During this time, the page above the roller 81a is pushed by the roller 81a in the direction of arrow C. The page is turned.

In this way, printing is continued on the page-turning passbook 5a.

[Problems to be solved by the invention]

According to the above-mentioned conventional method, since page turning depends on the frictional force with the passbook due to the forward and reverse rotation of the roller, a plurality of pages may be bent at a time. As described above, the returning operation is performed, but there are cases where the returning operation cannot be completed. As shown in FIG. 7 (f), if the passbook 5a is sent as it is in the B direction, the next page is folded. Then, there is a problem that the passbook 5a becomes defective, it takes time and effort to switch to a new passbook and record and issue the transitional transaction data, and also annoy the customer such as waiting for processing.

It is an object of the present invention to provide a page turning mechanism that can prevent page breaks.

[Means for Solving Problems] FIG. 1 is a principle diagram of the present invention. In the figure, 5 is a passbook, 81 and 82 are rollers, 88 is detection means for detecting page flipping, and 84 is a shaft 83 of the roller 81 on the page-turning side of the passbook medium 5.
The rotary member 84 is rotatably fitted to the rotary member 84. The rotary member 84 is provided with a bulge that exceeds a predetermined amount of the page when the page is turned and the front end of the rotary member 84 is rotated.
When the page is flipped up, the engagement with the page is released. The first protrusion 86 is provided on the rotating body 84, and the engagement of the first protrusion 85 with the page is released. At the same time, the rotating body 84 is rotated in the opposite direction by its own weight, and the tip end is detected by the detecting means 88.
The protrusion 87 of the rotary body 84 is provided on the rotating body 84, and when the swelling of a plurality of pages occurs in page turning, even if the upper page is flipped up, the rotating body is engaged with the bulge of the lower page. Is a third protrusion that prevents the reverse rotation of the.

Therefore, the rotation of the rotator 84 in the reverse direction is prevented by the third protrusion 87, and the flip-up of the page is not detected by the detecting means 88.

[Action]

When the page turning of the passbook 5 is started by the mutual reverse rotation of the plurality of rollers, the tip of the first protrusion 85 engages with the bulge exceeding the predetermined amount of the page to rotate the rotating body 84,
When the page is flipped up, it disengages from the page. Then, the second protrusion 86 rotates the rotating body 84 in the opposite direction by its own weight, and the tip of the second protrusion 86 causes the detecting means 88.
Detected by.

If a plurality of pages are turned up, even if the upper page is flipped up, the third protrusion 87 is engaged with the bulge of the lower page and prevents the rotating body 84 from rotating in the reverse direction. Then, since the detection means 88 does not detect the tip of the second protrusion 86, it is possible to know that a plurality of pages have been turned, and it is possible to take measures such as discharging the passbook medium.

In this way, it is possible to prevent a page from being folded due to the turning of a plurality of pages.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. The same reference numerals denote the same objects throughout the drawings. In FIG. 3, the components corresponding to those in FIG. 1 are shown surrounded by a one-dot chain line.

FIG. 2 is a side view of the bookkeeping mechanism, showing rollers for the page turning portion 8a.
A spring 84b is rotatably wound around a shaft 83 of 81a.

As shown in FIG. 3, the spring 84b includes an engagement lever 85.
a, a flip-up detection protrusion 86a, and a double feed detection protrusion 87a are provided.

The engagement lever 85a has the same function as the engagement lever 85a described in the conventional example, but is integrally formed with the double feed detection protrusion 87a.

The double-feed detection protrusion 87a is a spring that is engaged with the bulge of the lower page even if the upper page is flipped up when a double feed occurs in page turning.
Prevents reverse rotation of 84b.

The operation is described with reference to the operation process chart of FIG. 4 because of the above-mentioned structure. First, as shown in FIG. 4 (a), the rollers 81a and 82a rotate in the arrow directions to transfer the passbook 5a. And roller 81a, 82
a stops at the turning position while holding the passbook 5a.

Next, as shown in FIG. 4 (b), when the roller 81a is rotated in the forward direction and the roller 82a is rotated in the reverse direction, the page of the passbook 5a is bent and bent. The engagement lever 85b is pressed against the curved surface of the page to rotate the spring 84 in the forward direction, and the flip-up detection lever 86a also rotates in the same direction to release the shielding of the optical sensor S1. By this cancellation, the progress of page turning is detected.

As shown in FIG. 4C, when the turning of the roller 81a is advanced, the curved page is flipped up above the roller 81a. If there is no double feed on the page turned up here, the engagement between the page and the engagement lever 85a is released, and there is nothing that engages with the double feed detection protrusion 87a. Then, it rotates in the opposite direction and returns to its original position, and the shield plate 86b is replaced by the optical sensor
Is blocked to detect page flipping.

If there is a double feed, as shown in FIG. 4 (d), even if the engagement between the page and the engaging lever 85a is released, the second page remains curved and the double feed detecting protrusion 87a is present. , The spring 84a is prevented from rotating back to its original position.

As shown in FIG. 4 (e), the roller 82a is retracted by the excitation of the plunger magnet 10, and the roller 81a is rotated in the opposite direction to perform the returning operation for returning the curving of the page to the flat state.

When the curving of the page is returned by the returning operation, the engagement between the curving page and the double feed detecting protrusion 87a is released, so that the spring 84b rotates in the reverse direction as in FIG. 4 (c) and the shielding plate 86b. Only when the light sensor 88a shields the page, the page flip-up is detected. If the bending does not return by the returning operation, the returning operation is repeated again.

When the bending does not return even by the returning operation again, as shown in FIG. 4 (f), the roller 82a is closed and then the rollers 81a and 82a are rotated to move the passbook 5a in the direction of the arrow B by a predetermined dimension. Roller 82 after removing
The a is evacuated and the returning operation of FIG. 4 (e) is performed again.

If the curve still does not return, the roller 82a is closed and the passbook 5a is moved to the arrow B as shown in FIG. 4 (f).
The guidance is displayed on the display 4 so that the sheet is sent in the direction of the sheet to be discharged, the page is manually turned, and the sheet is reinserted.

In this way, since double feed is detected and the double pass is eliminated and printing of the passbook 5a is continued, it is possible to prevent a passbook defect due to a page break.

Although the above has described the case of the bookkeeping machine, it is needless to say that the present invention can be applied to other transaction devices, such as a CD and an ATM having a bookkeeping mechanism with a page turning function.

〔The invention's effect〕

As described above, according to the present invention, it is possible to detect a plurality of page turnings of a passbook and prevent a passbook medium from being defective due to a page break.
